1. Summary This study compiles and analyzes a dataset of 9,262 environmental incidents that occurred between 1996 and 2012 and were attributed to the major bitumen operations in the lower Athabasca River region. It describes the Alberta Environment and Sustainable Resource Development (AESRD) routine disclosure process and documents errors in that process. The study describes the frequency of environmental incidents over time by incident type and company and provides annotated examples of the incidents that elucidate the performance of the bitumen operations in the context of air, water, groundwater, and land management and reporting. The study documents public complaint-related incidents, places air-related incidents in the context of ambient air quality and quantifies contraventions in relation to enforcement actions. It explains why environmental incidents are frequent in the region and identifies questions that require further investigation. Recommendations as to how to improve environmental management in the bitumen sands region are provided. The study finds the following: Data Management and Records Disclosure The Alberta government’s routine disclosure process fails to deliver timely, accurate, errorfree, and complete information. Procedures used to store, manage, and disclose information from the Environmental Management System database are dysfunctional. The system cannot be remedied by minor modifications and should be replaced. The AESRD routine disclosure process provides information to the public, after significant delay, that is essentially unusable without significant programming expertise and line by line editing; different records are released for essentially identical information requests; the information lacks an indeterminate number of records to which the public have right of access. The practice of not updating the EMS database when incident status changes from open investigation to closed deprives the public of critical information and prevents public involvement in environmental enforcement. Evidence is presented that indicates that the most serious incidents are never made available to the public. Repeated attempts to address deficiencies in the AESRD disclosure process met with no success. A meeting to be held between the authors and senior bureaucrats was abruptly cancelled by government after it was provided with an agenda of discussion items. For a government that is attempting to portray itself as open and transparent, its actions suggest that openness and transparency have not yet progressed beyond policy statements. Industrial self-reporting as the foundation of the environmental record, both on the part of Alberta government and the Alberta Energy Regulator, fails the test of openness and transparency that are essential to good governance. Responsibilities for reporting should be shifted to monitoring agencies that report directly to the public. Launching of the Alberta government’s open data portal in May 2013 did not address deficiencies in government transparency in regard to environmental incidents. Querying the portal with various search terms failed to find real-time data, monitoring reports, or any relevant information on spills, leaks, public complaints, or other environmental incidents.

Environmental Incidents A minimum of 9,262 environmental incidents are documented in the EMS database within the study region over the 1996-2012 period. The incidents documented represent an unknown fraction of the true number of incidents occurring per unit time because of the combined effect of missing records, redacted records, multiple contraventions subsumed under a single incident, under-reporting, and the fact that other kinds of incidents, such as pipeline spills, are typically not reported to the EMS database. A recurrent feature of the incidents is that the volume, duration, and chemical composition of the releases to air, and spills, leaks, and discharges to land or water are unspecified or unknown. This lack of basic data limits the ability to understand industrial impacts and represents a significant deficiency in government and industrial monitoring. Overall, environmental incidents from the period 1996 through mid-2012 reached the highest frequency of occurrence during the period 2008 through 2011. Incidents related to air emissions and air quality were the most frequent, and comprise 64.9 % of the total incidents. The bitumen operations process large volumes of potentially hazardous materials, are technologically complex, operate within narrow engineering tolerances, and are characterized by feedbacks, which render them sensitive to upsets that result in environmental incidents. Small events can have large impacts on plant operation; examples are provided. An engineering and environmental audit that is consistent across all company approvals should be conducted to identify whether particular processes, machinery, and practices give rise to a disproportionate number of incidents. Incidents demonstrate that industry increases the sediment loading of the region’s waterbodies above natural background levels. Little is known of the environmental incident record prior to 1996. There is a 29-year data gap from the beginning of operations in 1967 through 1995 about which no incident information is currently available. This lack of information constitutes a major environmental uncertainty. Examination of the Alberta Energy Regulator pipeline releases database further characterizes the industrial disturbance regime of the region. There were 1,179 pipeline releases in the study region over the period of record. The reliability and completeness of the releases data and the regulators’ practices as they relate to data verification and public disclosure are evaluated. Questions posed to the Alberta Energy Regulator were not answered as of the date of release of this report. An audit of the Alberta Energy Regulator is recommended. The performance of industry as it relates to public disclosure of information is examined in relation to issues and recent incidents attributed to CNRL, Syncrude, Suncor, Plains Midstream, Penn West, Enbridge, and Apache. Public disclosure by industry is found to be inadequate.
7
Enforcement A minimum of 4,063 alleged contraventions (perceived violations of legislation) occurred between 1996 and mid-2012. Syncrude Mildred Lake (46.95 %) and Suncor Oil Sands (39.65 %) were responsible for the majority (86.6 %) of the 4,063 alleged contraventions. The contraventions were chronic and repetitive and indicated little progress towards better management practices. The environmental enforcement rate in the bitumen sands region of northeastern Alberta is 0.9 % of the alleged contravention rate. In comparison, the average enforcement rate for violations of the Clean Water Act in the United States for the period 2004-2007 was 16.0 %, over 17 times the environmental enforcement rate in Alberta’s bitumen sands region. Public involvement and media attention may increase the frequency of enforcement actions. Because enforcement is rare, and most enforcement actions impose only minor financial penalties (median penalty $4,500.), industry may have little incentive to undertake improvements that might result in increased costs. The Alberta government monitors for a small number of substances released to the environment. A larger set of substances is reported by industry to the National Pollutant Release Inventory (NPRI). However, these compounds are not federally-regulated per se but are simply tabulated, nor is the NPRI list of compounds a complete enumeration. There is no systematic monitoring or tabulation of releases for a large number of substances such as naphtha, diesel, gasoline, total hydrocarbons, sewage, and coke particulates. This presents a significant set of unknowns. Given the revolutionary changes in communications technology that are transforming civilization, the internet may be a key to facilitating improvements in environmental management. There is little to lose and much to be gained. If, as the Alberta government has stated, it is a “good steward” with “nothing to hide”, then effective disclosure of objective information is needed to allow the citizenry to grant government the social license to continue. Conversely, if there are serious issues disclosed, the public, through democratic processes, can participate in the discussion as fully-informed citizens. In either case, a comprehensive information and video network might be effective in ensuring transparency, encouraging improved management, and restoring trust in government. The time for “open government” has arrived. Government should adopt a “big data”, free-market approach to information. If the public deems the information worthwhile, it will use the data. Media will produce news items. If the public deems the information worthwhile, the news items will continue. If the public does not see worth in the news, then that news will cease to be reported. Let the free market decide what is valuable information. “Big data”, “open government” is the future. It is cost-effective, inclusive, and democratic. In order to improve environmental management of the bitumen industry, three changes in government procedure are recommended. (1) Alberta’s environmental laws must be more effectively enforced. (2) Environmental incident information should be made available in real-time format via the internet. Incident descriptions should be posted online as they occur (with real-time redactions to 8
protect personal privacy). Data, toxicity results, ambient air quality, and spill volumes and locations should be posted online as they become available. The format of text should be truetext, not images of text. Seven-day letters and monthly and annual environmental monitoring and compliance reports submitted by industry to government should be posted online. (3) Remote, real-time cameras should be installed and brought online at a network of selected locations, including tailings ponds, wastewater ponds, river reaches below outfalls, and major emissions sources. The combination of online real-time incident information and comprehensive video feeds would increase government transparency and encourage improvements in management.
2. Introduction International interest and discussion about the exploitation of western Canada’s bitumen deposits has taken various forms ranging from investment opportunities, “energy security”, “ethical oil”, “dirty oil”, royalty regimes, pipelines, aboriginal rights, pollution, climate change and greenhouse gases, environmental regulations, enforcement, and monitoring. One of the chief concerns identified by a number of recent reviews (e.g., Dowdeswell et al. 2010; Auditor General of Canada 2010) is insufficient high quality monitoring data. Few would dispute the view that bitumen development has proceeded more rapidly than has accumulation of scientific understanding about the effects of that development. As such, it is imperative that increased efforts are made to gather as much relevant data as possible in the shortest time. There are three ways to approach that task. One approach is to improve existing monitoring, such as recent improvements in the Wood Buffalo Environmental Association air monitoring program. Another approach is to design and implement new monitoring programs in order to gather new data that will, over time, provide a clearer understanding of the effects of industrial development. Another approach is to compile pre-existing archival data in order to reconstruct the history of environmental events and management. One source of archival data is Alberta’s Environmental Management System (EMS) database, which is the focus of this study.
2.1 Environmental Management System (EMS) The Alberta Environmental Management System (EMS) is a database that contains environmental incidents related to air, land, and water that have been reported by industry, the public, and by government agencies. Each incident reported to the system contains a number of fields that identify the record, such as call date, call time, incident number, approval number (see Appendix 2 for definition of “approval”) and company name of the responsible party (if applicable), followed by incident information, comments, and incident details (if any). Until recently, incidents were recorded into the database by Alberta Environment environmental protection officers (EPOs). Presently, calls into the EMS are fielded by a privatized call center. The EMS database is a potentially valuable resource for both environmental scientists and the concerned public. Because the database contains information as to date, time, location, and nature of an incident, it can be used to determine critical details about environmental history of a region—the what, who, when, where, how, and why.

Request for EMS data are made via the “routine disclosure” process and are submitted to the Access and Privacy Branch of Alberta Environment and Sustainable Resource Development (AESRD, i.e., the Freedom of Information and Protection of Privacy Office, in short, the FOIPP office). The requesting party submits a deposit along with a form that specifies the kind of query to be conducted. In the case of this study, e.g., a list of approval numbers (company operations), a time frame, and the kind of information needed. The FOIPP office responds with an estimate of the cost of the routine disclosure. If the cost estimate is accepted, the routine disclosure proceeds. The records are queried by administrative staff who then send the results to the FOIPP office for vetting. The FOIPP office redacts (deletes) entire records, ostensibly if the records pertain to open investigations or redacts partial records that contain personal information. Apparently improper redactions and failures to disclose valid records are discussed in the report.
2.2 Scope and Objectives This study focuses on incidents attributed to a subset of large, well-established bitumen operations in the bitumen sands region over the period 1996-2012. Smaller companies or those not directly involved with bitumen exploitation were not included in the study (Box I.). As a consequence, the number and type of environmental incidents documented in this study are a subset of the incidents in the region. Therefore, the total effect on the environment caused by industry operating in the region is greater than the effect that can be documented from the incidents in this report. Although an information request was Box I. This Study Focusses on a Subset of the submitted to government (see Methods) for all Companies Operating in the Region. incidents in the bitumen sands region from the Other industrial operations have been found to cause beginning of the records to the present, there environmental impacts such as loss of wetlands and are essentially no electronic records prior to impact to the aquatic environment. 1996 (there were five records out of a total of 9,262). The fact that the lowest incident One example: Wood Buffalo South Industrial Park Ltd. number disclosed was 3 (dated 31 March (MD of Wood Buffalo, Plan 7620627, Lot A), Administrative Penalty, Assessed: $4,500. under the 1996) reinforces the view that there are Water Act 36(1), 142(1)(h); “The Company conducted an essentially no pre-1996 electronic records. unauthorized activity, the construction and operation of Inspection of incident numbers and dates for the Works, specifically, infilling of all or portions of the earliest electronic records further indicates wetlands; changing the direction, location and flow of that the electronic records system was water; and causing siltation in an unnamed creek, all of which caused an effect on the aquatic environment. Paid 1 probably established in March 1996 and that October 2012.” (Alberta Government 2012). incident numbers were non-sequential until September 1996. According to James Greengrass (Chief Information Officer, AESRD, pers. comm. 3 April 2013), “The records and information prior to 1996 are held in various places depending on the nature of the record. Some will have been transferred to the Provincial Archives and, as you may remember, these are not accessible at this time while critical structural repairs are made to the storage facility.” As a result, the data analyzed in this study are restricted to the period 1996 to mid-2012 even though bitumen operations began in the region in 1967. Further investigation revealed that a small amount of pre-1996 information exists for Suncor and Syncrude, but was not made available in spite of requests. The essential point is that this study was limited to the period 1996-2012. 10
Because concerns arose early in the process in regard to record retrieval and freedom of information, the original scope of the project was expanded to include both the environmental record and the process of ascertaining that record. The objectives of this study were to: (1) compile a searchable database of environmental incidents that have occurred in the bitumen sands region of Alberta and make that available to the public; (2) describe and evaluate the AESRD routine disclosure process as it relates to EMS data; (3) describe the frequency of environmental incidents over time by incident type and company; (4) document a representative subset of the incidents that elucidate the performance of the bitumen operations in the context of air, water, groundwater, and land management and reporting; (5) document public complaintrelated incidents; (6) place air-related incidents in the context of ambient air quality; (7) place the contraventions in the context of management and enforcement, (8) explain why environmental incidents are frequent in the study region; (9) identify questions that require further investigation; (10) evaluate “freedom of information” as practiced by government and industry in relation to environmental incidents; and (11) recommend how environmental management in the bitumen sands region can be improved. Note to the reader: This is not a reader-friendly report. After much correspondence and discussion with the Alberta government, we were presented with an error-filled dataset of incident descriptions. The data, as presented to us, were not amenable to standard statistical analysis and deduction. Therefore presentation of the data required that we first document the disclosure process itself and then provide representative incidents accompanied by context and commentary to allow the reader to reach his/her own conclusions. We recognize that our discussion of a subset of the 9,262 incidents may not satisfy all readers. The incidents were chosen to illustrate particular topics of discussion. In the spirit of full disclosure, the entire database is available to readers who request it. For the convenience of readers, an abbreviated version of the incident data is provided in Appendix 7.
3. Methods 3.1 Disclosure and Processing of EMS Records 3.1.1 The Retrieval Process It is relevant to review the information structure and retrieval process. Until recently, information was entered into the system by environmental protection officers (EPOs) who staffed the phone lines and responded to information and complaints. Environmental Protection Officers are knowledgeable people. They understand the database, the operations, and the technical information. Under the current Alberta government system, the public does not have direct access to environmental incident information. In order to access this information, an application is filed with the AESRD FOIPP office. The request is assigned a FOIPP agent. The FOIPP agent does not have access to the database, has no knowledge of the database, the operations, or the technical information contained in the database. The FOIPP agent serves as a liaison between the government and the public. The FOIPP submits the information request to clerical staff. The clerical staff have access to the database but no knowledge of the database structure or its technical information. Information technicians are knowledgeable of the database structure and maintain the system but they are unavailable to the public. Enforcement (compliance) staff are 11
involved in the request. They provide information to the FOIPP agent as to what incidents are open files. Open incident files must be redacted by the FOIPP agent. Once clerical staff have produced the results, either a paper or electronic copy of the disclosure is sent to the FOIPP agent. The procedure then followed has changed over time and differs among FOIPP agents. Typically, if the results are in paper copy format, the paper is scanned to become an electronic copy. The FOIPP agent, working with an electronic copy, then reads all of the records and then (using Adobe Professional) redacts incidents that have been flagged by enforcement staff and removes any personal information from other records. The redacted routine disclosure is then provided to the requesting party as paper and/or electronic copy. 3.1.2 The EMS Data Requests Two routine disclosure requests were submitted to the Access and Privacy Branch of Alberta Environment and Sustainable Resource Development. The first request, for call summaries, was submitted on 23 July 2008 for incidents attributed to a set of company approvals (Table 1, Figure 1) from the beginning of records until the end of records in July 2008. Approval numbers (company operations) were identified a priori from study of incidents on file at the Alberta Environment records library. Company operations that were not found in the initial search of incident records at the Alberta Environment library were not included in the routine disclosure request; therefore the company approvals analyzed in this study comprise a subset of currently approved bitumen operations. The currently approved bitumen operations and the leases that they occupy are themselves a subset of the companies operating in the study region and of the total bitumen leases (Table 2, Figure 2), most of which are currently inactive. Virtually the entire region has been leased for bitumen exploitation. The company approvals (Table 1, Figure 1) tied to the routine disclosure incidents correspond to the companies listed in the lease map (Table 2, Figure 2), albeit loosely. For example, Suncor Fort Hills (approval 151469) corresponds to “Fort Hills”; Canadian Natural Horizon (149968) corresponds to “Canadian Natural”; Suncor Base Operations (94) corresponds to “Suncor”, and Suncor – MacKay River (82973 and 48408) corresponds to “Suncor” in Figure 2. The situation is dynamic and complex and the vernacular use of similar but non-identical names for the same operations highlights the need to use unique approval numbers for accurate attribution of incidents. Errors were noted in the routine disclosure information from the outset. For example, the FOIPP advisor indicated that the 1700 pages of records pertained to notification releases for Syncrude Canada for 1970-2008 and for Suncor, Great Canadian Oil Sands, Steepbank, Millennium properties for 1967-2008, and for Albion [sic] Sands, Devin [sic] Canada, and Canoco [sic] Phillips. The records, however, pertained to all types of incidents, not only to notification releases, and the records released essentially began in 1996, not 1967 or 1970. Additionally, the paper copy contained truncated words, typographic errors, and mis-spellings that made automated text recognition difficult. The records were evaluated and found to contain environmentally significant information. Therefore, because the records were delivered in paper format and in paragraph form, the documents were scanned and text recognition software was used to extract the information. Data manipulations were used to create a structured excel spreadsheet of records and fields containing true text and numeric values. 12
The first set of routine disclosures was provided in paper copy. Digitizing the 1700 pages of call summaries was completed with a flatbed scanner and the computer program PDF2XL OCR (CogniView). The original scanned files were saved as text searchable PDFs, which were then converted to an Excel spreadsheet. The PDF2XL OCR software allowed for comparison with originals to correct text recognition errors, as well as cell alignment such that the appropriate content was captured in each cell. Once all documents were digitized into the Excel format, hyperlinks were inserted to allow the user to view the original pdf files. The second request was submitted on 31 August 2012 for incidents attributed to company approvals (Table 1) for the period 1 January 2008 to 31 August 2012. The request was for call summaries, call information, and incident details. The temporal overlap with the first request was done so that the consistency and reliability of the disclosed information could be evaluated. The data output was requested to be electronic file, readable text, and as paper copy. Materials began to be delivered in November 2012. There were numerous errors and problems with the output such as text being delivered as images, ghostly text not being retrievable as text, text recognition software being unable to recognize corrupted text, and call information and incident details missing. A request was made that the data output be delivered in its native text format in either a spreadsheet or a comma delimited csv data. This request was denied. AESRD stated that the only format available for output was pdf. They were asked why. AESRD stated that, depending on the date and source, software did not exist to do what was requested, that the expertise was not present to deliver that kind of output, and/or that policy required that the material be delivered in pdf format. It was then communicated to the FOIPP advisor that the original EMS data are in a database or spreadsheet format containing true text and numeric values; that this information is evidently printed onto paper, which is then scanned, converting the original information from a structured database into pdf format; that the pdf material must then be reconverted to true text and numeric values and reformatted into a usable spreadsheet format before it can be used. The FOIPP advisor was informed that the process followed by the FOIPP office introduced errors and was extremely inefficient. AESRD responded that there were no alternatives. Over the ensuing three months, the FOIPP office continued to produce iterations of errorprone, corrupted output. By February 2013, it was clear that clean, error-free, text and numeric output would not be delivered and that other means would be needed to render the information usable. Therefore, the various pdf files were sent to a data programmer who was tasked with extracting the information into a structured excel spreadsheet of records and fields containing true text and numeric values. The text output supplied by the government derived from scanning of printed pages resulted to two qualities of output. One type of output was readable and relatively consistent in layout and resulted in text that could be manipulated via programming to create a spreadsheet of reformatted data. The second type of output resulted in unpredictable ordering of data items. Although all text was present, it could not be associated reliably with a data field. This problem arose because the text was recognized incorrectly by the OCR during the initial scanning process (e.g., zeroes as OHs (0,O), ones as ELs or EYEs (1,l,I), fives as ESs (5,S), TEE as EFF (t,f) as well as missing characters) and because the OCR process during scanning inserted spaces into words where none should have been. This rendered the text unsearchable by any pdf display program. As a result, over 1000 lines of conditional regular expression code (example: if this, then rearrange in way 1, else, if that, then rearrange in way 2) was written to reconstruct the data in an 13
automated fashion. Some of the scanned documents contained sections that were, unfortunately, images rather than pdf and needed to be typed into the spreadsheet manually. The image problem was brought to the attention of the FOIPP Office months earlier, but the office was unable to rectify the problem for pages that contained redactions. Using the incident number as a unique identifier for all records, call summaries were merged with call information and incident details into individual records in one spreadsheet that contained all the data formerly in the pdf files. This approach processed more than 90 % of all records and the remaining ones were checked for errors manually. Some of the original data were incorrect, such as call times that ended before they began. These errors complicated the process of error checking because the program code looked for consistency in the original data which were sometimes inconsistent. After all data were merged, the output was compared manually against the originals in the pdf reports, and residual errors were corrected. After the material was rendered as a spreadsheet, the spreadsheets for the first and second routine disclosures were merged, the file was corrected for errors (as described below in Results), and a series of analyses began. The analyses were in three phases. Phase 1 described the frequency of incidents by approval and over time, by caller type, call type, and call reason. Tabulations of frequencies were based on the government’s categorization of each incident (see Appendix 1 for definitions). For example, for the call types “Alleged Contravention”, “Impact”, “Information Request”, “Notification”, “Pro-active Notification”, “Release”, “Waste”, and “Waste Management”, the number of incidents classified as that call type was tabulated, which allowed a description of how incident types varied over time and by company approvals. Phase 2 examined the incident details within the major categories of call types and call reasons in order to characterize the industrial incident regime. Phase 3 placed the incident data within the context of other datasets (described below) and studies. Note: In the text and in text boxes, when incident descriptions are quoted from the database, they are set in blue font to distinguish them from normal text. Glossaries provide the meaning of terms and abbreviations (Appendix 1, 2) used in the EMS database and in this report.

3.2 Other Data In addition to the routine disclosure data, relevant ancillary datasets and information were incorporated into the analyses as time and availability allowed. These were: Air quality monitoring station data collected by the Wood Buffalo Environmental Association (WBEA) were provided by WBEA Director, Dr. Kevin Percy. Air quality parameters included the hourly concentrations of H2S, TRS, SO2, and total hydrocarbons. Trace gas data derived from an overflight of the bitumen sands region were provided by Dr. Donald Blake (University of California, Irvine) and are published in Simpson et al. (2010). Air quality measurements included 77 different hydrocarbon gases measured from air canisters filled while onboard a specially-equipped aircraft, and high-frequency real-time measurements of SO2, NO, NO2, NOy, CO, CO2 and O3. Excerpts of annual, monthly, and quarterly environmental reports by industry to government were photocopied from the Alberta Environment Twin Atria records library. Company approvals were downloaded from http://environment.alberta.ca/01519.html. These documents specify the conditions under which the companies operate. They define a set of regulatory criteria such as reporting requirements and limits for emissions and releases. Pipeline releases within the study region that were reported to the Energy Resources Conservation Board (ERCB) between 1975 and 2013 were provided by Leslie Young (pers. comm. June 2013; Global News (2013)). The full dataset for the province of Alberta consists of 61,587 pipeline incidents and that for the study regions consists of 1,179 pipeline incidents. Each record contains a variety of attributes that include incident number, date, location, source, failure type, licensee name, environment affected, pipeline damage type, substance released, volume released, and volume recovered.
4. Results 4.1 Errors in the Record Disclosure 4.1.1 A Comparison of Two Routine Disclosures for the Same Time Period In order to assess the consistency with which AESRD disclosed records, the second routine disclosure overlapped in time with the first routine disclosure. The information request was for the same set of company approval numbers and spanned the period 1 January 2008 to 31 July 2008. If there were complete consistency of record disclosure, the first and the second routine disclosures should have produced the same set of records during the period of overlap. There were 1,073 records during the period of overlap, composed of 447 “old” records and 626 “new” records. The records were then merged if the incident numbers matched in the old and new records. Records without an incident number (e.g., “closed, information only”) were inspected manually based on attributes of the record (company, and day, month, time and description of the incident) to determine if any were shared in the “old” and “new” datasets. Of the 1073 records, 416 incidents were found in both datasets (832 records). There were 221 uniquely numbered incidents (composed of 17 incidents in the old dataset and 204 incidents in the new dataset). There were 20 unique unnumbered incidents (composed of 14 incidents in the old dataset and six incidents in the new dataset). Unique incidents were found in one or the 19
other of the datasets and are therefore an index of inconsistency in record disclosure, i.e., errors. The error rate for the production of records during the period of overlap was 241/1073, or 22.46 %. This is a high error rate and raises the question whether the records disclosed represent a subset of the true incident record. 4.1.2 A Comparison of Two Methods of Record Retrieval Although the second routine disclosure request specified complete records (the “YYN option), the first attempt by government to produce those records instead delivered basic records (the “NNN” option). This setback provided an opportunity to further examine the consistency of record disclosure. The consistency of record disclosure was compared for two methods of data retrieval within the second routine disclosure. The first method (“NNN”) provided basic call summaries such as incident, sheet, and call numbers, dates, company, and basic comments (Figure 3). The second method (“YYN”) provided all of the preceding information and further call information and incident details if they existed (Figure 4). In theory, the two methods should produce an identical set of incidents; the salient difference is that YYN records should contain additional information. The output was compared by incident for the combined NNN and YYN output. There were 3,647 valid records, of which 2,436 records had both NNN and YYN output, 1,099 records lacked NNN output, and 112 records lacked YYN output. There was a total of 1,211 inconsistent records or an error rate of 33.21 %. The lack of consistency indicates serious problems with data retrieval and government transparency. For example, the NNN query that provided only call summaries was missing a minimum of 1,099 records.

The high error rates in the record disclosure prompted a query to AESRD as to how such erroneous results might arise. AESRD wrote: “... the two line contacts were providing me [the FOIPP advisor] with different search criterias [sic] for the reports which I think is the problem. I've had discussions with both contacts and I think that is where the problem lays [sic]” (C. Hamelin, AESRD, pers. comm. March 2013). The search criteria used by two staff to search the same operation (Syncrude Mildred Lake) for the same “incident date” period were attached to the email. Staff member (a) set “incident type/sub type” to include Approval Requirement, Discharge, EPEA, and Spill but did not define a “call date” period. Staff member (b) did not define incident type but did set a “call date” period. It is not clear why the staff used different criteria (they were not specified in the routine disclosure request) nor is it clear how or even if these criteria would affect the search results. The AESRD Chief Information Officer (CIO), James Greengrass, added: “The ‘executive summary’ answer to your question 1 is that different operators are using disparate search parameters in response to the same query. Why that is happening is, of course, a whole separate conversation. As you may be aware, our FOIPP Analysts do not have direct access to EMS; they have to access this information through Business Unit personnel. Depending on the nature of the information being gathered they may have to deal with operators from different Business Units, 21
sometimes in different parts of the province.” The response is significant for two reasons. (1) It assumes that because different criteria were used, the discrepancies are explained, but this statement is a hypothesis, not an explanation. (2) It does not provide a remedy. The implicit message is that this is the way the system works, that the errors are inherent in the process, and that this is acceptable from the Alberta government’s perspective. There appears to be a lack of recognition as to what constitutes acceptable results. The second routine disclosure query, for example, was for all incidents in the EMS database between the dates of 1 January 2008 and 1 September 2012 for a defined set of company operations. For such a query there is only one correct answer. For the CIO to state that the erroneous results were due to different people querying the system is similar to maintaining that the correct sum for 2 + 2 depends upon who does the sum. The different search parameters that were used were as follows: (a) the “NNN” search provided the incident summaries; and (b) the “YYN” search provided the incident summaries plus call details and incident details. In both cases, the searches were for all records between a set of dates for particular approvals. The query results should have produced an identical set of records that differed only in level of detail, but that was not the case. The intent in using two queries of the same set of records was to evaluate the reliability of the output from the FOIPP office. The results demonstrated that the routine disclosures were not reliable. 4.1.4 Errors in the Data In addition to the missing records (above), the records were often missing information such as incident details and call details (see the above section). Secondly, in many cases, insufficient information was released to ascertain what substances were involved in an air contravention. Thirdly, a given incident may involve several contraventions, such as for hourly and daily exceedances, or involve more than one substance or regulated attribute such as sulfur dioxide and flaring. It is therefore difficult to ascertain the overall frequency of air contraventions for specific substances. Fourthly, because optical character recognition was used in the government’s scanning process (prior to releasing the records), many words were rendered as non-words, with either deletion or insertion of spaces or rendering of incorrect letters or numbers. Spelling mistakes and word abbreviations were exceedingly common. These problems were corrected as far as possible, but correcting thousands of non-words is difficult to achieve. Many non-words can be valid entries, such as “AMS 12”, while many other non-words are errors, such as “AMS 112”. In other cases, “AMS 12” is incorrect and should have been rendered as “AMS 2”. Because of these considerations, normal spell checking cannot be used. Each record has to be read and corrected manually against a paper original. In the present information request, the introduction of thousands of transcription errors by the FOIPP office seriously damaged the database and resulted in hundreds of hours of line by line corrections. The number of permutations in word renderings due to the combination of poor spelling in the AESRD data and the insertion and/or deletion of letters or spaces, and the insertion of incorrect letters (such as the numeral one rendered as the letter l (ell)) in the digital data supplied by AESRD resulted in gibberish that required significant effort to translate back to English. The word “exceedance”, an important one in such a dataset, provides an example. Search for “exceedance” would not find incidents with the following alternate spellings: “excedeeence”, “exccedance”, “excediance”, “excecdance”, “exceeence”, “excendence”, “exeeedenee”, “exceedanee”, “eceddance”, “excedeence”, “exceedace”, “excednence”, “excednece”, 22
“exceendence”, “xceedence”, “excceedence”, “exceedan”, “exce”, “exceeda”, “exc”, “exeedance”, “exeeedence”, “exceddance”, “exceedence”, “esxeedance”, “exceendence”, “sexceedence”, “excedance”, and so on. A typical comment (extracted from incident 448245), with 52 inserted or deleted spaces (which created non-word errors) in yellow highlight, follows as provided by AESRD: “Commenffi: Ca l l er reporting a f l aring event t h a t resulted i n > 2 0tons S02 being rel eased. The compressor, 2K4 02 , tripped due to h i gh temperat u re . This c aused f l ari ng from from 52C309 . I nitia l c a l c u l a t i on yest erday put the value b e l ow 20tons and rec a l c u l a t i on t oday i ndi c ated t ha t t hey were over.” When limited to valid text strings, the comment would read: “... reporting a event resulted > 2 S02 being. The compressor tripped due to. This from from 52C309 . put the value and were over.” After corrections, the comment was rendered as: “Comments: Caller reporting a flaring event that resulted in > 20 tons S02 being released. The compressor, 2K402, tripped due to high temperature. This caused flaring from 52C309. Initial calculation yesterday put the value below 20 tons and recalculation today indicated that they were over.” More than five thousand corrections were made before analyses could begin. Although it might appear pedantic to correct spelling errors, such errors can render a database unusable. Because this type of database is text-intensive and largely consists of comments, keyword searches are the most powerful method available to extract relevant information. If a keyword is spelled incorrectly, it does not exist to the search algorithm. As a result, some text searches may fail to find matches. For example, search for a term such as search for “contravention” would not find incidents with the spelling of “contravetion” or “contravent ion”, or “contrvention”. If the term of interest is “spill”, records with the word rendered as “sp ill”, “spi ll” or “spi11” (the latter word with the numeral one in place of the letter l), would not be found. The onerousness of the task of correcting mis-rendered words is exacerbated when it is realized that the original data held by AESRD are in text format. It is the disclosure process used by AESRD that introduces the majority of the errors. Considerable effort was expended to produce a usable, error-free database. Poor English usage and spelling mistakes were corrected when they made the material ambiguous or difficult to read. The database, which is available upon request at no charge, contains notes [in square brackets] added to clarify text entries. When questions arose about the disclosed material, it became clear that the only people qualified to answer questions were the EPOs. As a result, early in the study, technical questions were posed directly to the EPOs, who were helpful and knowledgeable. After some queries were answered, however, AESRD stated that questions could no longer be directed to an EPO, that questions should be directed to the regional compliance manager. Soon thereafter, the regional compliance manager stated that questions should be directed to the FOIPP office. The researchers were then informed that questions should be directed to a “Single Point of Contact with ESRD.” 4.1.5 Redaction Follow-up There is a two-year limitation on the Alberta government’s ability to lay charges under the Environmental Enhancement and Protection Act and the Water Act (A. Driedzic, pers. comm., 2 July 2013). After two years, there would appear to be little reason to maintain incidents as open investigations. Therefore incidents that were redacted from the 2008 routine disclosure 23
as open investigations should have been closed four years later (by 2012, when the second routine disclosure was made). As a consequence, the authors requested that AESRD release those incidents that were redacted from the first routine disclosure. Four files were received in March 2013, one each for Syncrude Mildred Lake (approval 26), Suncor Oil Sands (approval 94), CNRL Horizon (approval 149968), and Shell Canada Jackpine (approval 153125, also referred to as Shell Canada Fort McKay). Redacted records were requested for other approvals, such as Petro-Canada Fort Hills (approval 151469), that were not provided with the above documents (for the results of the Petro-Canada request, see Test 3 (below)). Inspection of the files provided no earlier-redacted records. Instead it raised concerns about the government’s ability to retrieve records. Earlier-redacted records for incidents that occurred prior to late July 2008 were requested. Instead, an assortment of records was received that bore no resemblance to the request. It is difficult to summarize the output for the simple reason that the material appears unrelated to the requested information. Instead, the results of three tests of the responsiveness of the information are provided. 4.1.5.1 Test 1 Test 1 provides two sets of examples, both of the first ten newly-released records from two approvals. Suncor: 270847. Was not received previously, but the incident had closed on 2 November 2007 and therefore should have been disclosed in both of the earlier routine disclosures. 270842. Had already been received. 270737. Op cit., closed 18 November 2007. 270739. Ibid., closed 2 November 2007. 270838. Ibid., closed 2 November 2007. 270857. Ibid., closed 7 November 2007. 270963. Had already been received. 270745. Op cit., closed 7 November 2007. 270747. Ibid., closed 2 November 2007. 270715. Ibid., closed 2 November 2007. Of the first ten Suncor incidents inspected, eight of the ten had already been resolved and therefore should have been delivered in the routine disclosures. The other two incidents had already been disclosed and therefore should not have been part of the redacted list. The error rate in this sample is 100 %. The test also demonstrates failure to release records that were closed at the time of the request (in this test, eight out of ten records). Syncrude: 214889. Had already been received. 223117. Had already been received. 223119. Had already been received. 223113. Had already been received. 223006. Was not received previously, but the incident had closed on 5 June 2006 and therefore should have been disclosed in both of the earlier routine disclosures. 222921. Had already been received. 24
222852. Had already been received. 222858. Had already been received. 222800. Had already been received. 222740. Had already been received. Of the first ten Syncrude incidents inspected, one of the ten had already been resolved and therefore should have been delivered in the routine disclosures. The other nine incidents had already been disclosed and therefore should not have been part of the redacted list. The error rate in this sample is 100 %. 4.1.5.2 Test 2 As another test to determine if earlier redacted records were released in the follow-up request, the following approach was used. For each of the redacted records in the first routine disclosure, there is an approval (company), an incident date, and in some cases a sheet number (also a unique identifier). Searching that approval for that date and/or sheet number in the newlyreleased records indicated the following: Suncor, 3 January 2008, sheet number 196574. Not found in the new records. [Suncor incident 321358 (of 3 January 2008) was released in the second but not the first disclosure despite the fact it was a closed incident before the first RD was submitted, which demonstrates another failure to disclose requested records.] CNRL, 16 April 2008, sheet 199568. Not found in the new records. CNRL, 1 March 2008, sheet 198217. Not found in the new records. CNRL, between 15 November and 14 December 2007. Not found in the new records. [The CNRL file of “earlier-redacted” records contained three incidents, as follows: 290333 and 291588, both already released, and 288382, not received previously, but the incident had closed on 28 April 2008 and therefore should have been disclosed in both of the earlier routine disclosures.] Shell Canada – Fort McKay, between 30 April and 15 May 2008 (redacted space was sufficient for multiple incidents). No relevant records were released. There were eight incidents released for that period (302751, 301847, 301727, 301610, 301379, 301208, 301097, 300691), all of which had already been received. Screen captures of four pages from the first routine disclosure are presented (Figure 5) to illustrate multiple redactions on consecutive pages from incidents that occurred in spring 2008. These earlier redacted incidents were requested but not provided. The results of this second test for the disclosure of earlier-redacted, now closed, incidents corroborates the findings of the first test: a 100 % error rate. 4.1.5.3 Test 3 Although AESRD was requested in March 2013 to provide the earlier redacted incidents for Petro-Canada Fort Hills Energy (approval 151469), it did not do so. Reminder emails were sent in June 2013. On 19 June 2013, materials were received by email. As discussed with AESRD, there were nine redacted incidents that were requested, as follows: (a) four incidents between 4 December 2007 and 24 March 2008; (b) four incidents between 24 March 2008 and 6 May 2008; and (c) one incident between 14 May 2008 and 2 June 2008. The response: for (a) AESRD incorrectly defined the date range and provided information for 24 March 2007 to 4 December 2007—in other words the information provided did not pertain to the request; for (b) the date range provided was 24 March to 4 May 2008, not 6 May 2008 as specified; for (c), the 25
date range was correct. As for the production of earlier redacted records, the results were as follows: (a) four records were requested, but zero relevant records were provided and the incorrect date range was used; (b) four records were requested, one record was produced that had already been provided (incident 300670), therefore zero relevant records were provided; (c) one record was requested, one record was produced that had already been provided (incident 303363), therefore zero relevant records were provided. There were no disclosures of earlierredacted, now closed, incidents; the error rate was 100%. 4.1.5.4 Conclusions When asked to produce incidents that had earlier been redacted and were now “closed”, AESRD produced no records that corresponded to the request. The request revealed that many records that AESRD failed to disclose earlier were in fact “closed” at the time of the earlier requests and therefore should have been disclosed in the routine disclosures. The number of incidents released is a subset of the actual number of incidents. Therefore, the incident rates and degree of environmental disturbance indicated by the incidents are underestimates of the true values. From conversations with AESRD staff, it was revealed that “closed” incidents may be redacted if they are related to open investigation incidents. How this is decided, how “closed” incidents would be categorized closed if they relate to an open investigation, and whether such a nuanced justification for redaction is lawful are unclear. It is clear, however, that such a process fails the test of openness and transparency. 4.1.5.5 A “Mistake” Provided a Further Opportunity to Test the Reliability of AESRD Information In attempting to determine the number and kinds of redacted incidents, the authors corresponded via email and spoke by phone with a number of AESRD staff. In one set of exchanges (early in 2013), it was disclosed that there were 11 incidents redacted from the second routine disclosure for Syncrude, accompanied by two open investigations, and four incidents redacted from the Suncor data, accompanied by one open investigation. The incident numbers were provided. We then requested the numbers for incidents redacted from the other company approvals and were denied this information. After much correspondence, government stated that it had made a mistake in providing the redacted incident numbers for Syncrude and Suncor. Mistakes can provide an opportunity to learn and this was no exception. Recall that each incident in the EMS database is accompanied by a sequential incident number. Because our dataset contained a collection of dated, numbered incidents, it was possible to attach a date to the redacted incident numbers by bracketing. For example, if the lowest numbered redacted incident was 123456, by looking up the dates of incidents 123455 and 123457, the approximate date of the redacted incident could be determined. We did this for the Syncrude and Suncor redacted incidents. The oldest redacted incidents were dated approximately 14-15 February 2011 (Syncrude) and 23-25 March 2011 (Suncor). The oldest open status incidents dated from about two years prior to the request. Therefore, all incidents that were older than about 24 months should have been available for public disclosure. With the preceding information, we assessed the accuracy of the statements about the number of redacted records. When blacked-out (redacted) sections of the second routine disclosure original report were tallied for Syncrude, it was found that there were a minimum of 13 redacted incidents in the time window from 29 August 2012 back to 14-15 February 2011 26
(government indicated that there were 11). Beyond the oldest redaction date, there should have been no redacted incidents (because the government had provided the redacted incident numbers, the oldest of which was 14-15 February 2011 for Syncrude). There were, however, a minimum of ten more redacted incidents in the Syncrude report, for a total of a minimum of 23 redacted incidents. For Suncor, the results were more accurate. There were three redacted incidents found in the time window that extended back to 23-25 March 2011 (government indicated that there were four), and none found prior to that date. Our tallies for the redacted incidents included only those in which the entire record was redacted. Redactions of line segments, which are typical when personal information is redacted, were ignored. Therefore the records were redacted for reasons other than containing personal information. Secondly, each blacked out section was tallied as one record when in some cases the redaction might have consisted of more than one record. Therefore, we are confident that the redacted records were done so for other than privacy concerns, and, that the number of redactions that we tallied is less than or equal to the number of redacted incidents. What was the authority under which the additional Syncrude incidents were redacted and why were these incidents not included in the list of the redacted incidents? Additionally, there were 66 incidents disclosed with a status of “pending”. A source within AESRD compliance staff informed us that “pending” incidents should not be disclosed and was surprised that this had been done. The observation provides more evidence that AESRD records management and retrieval require a system replacement.

4.2 The Significance of Erroneous Disclosure The EMS data retrieval and disclosure process is cumbersome, inefficient, and errorprone. The reports provided in the routine disclosure lacked an indeterminate number of records and contained thousands of errors. Each component in the EMS system operates in a silo-type environment. Information control appears to be the overriding product of the system such that information accuracy, completeness, and timeliness are sacrificed. The system cannot correct its mistakes because those who detect mistakes (the users) are not allowed to communicate with the administrative staff who conduct the queries or with the data managers who can correct the errors. The EMS database and retrieval process is a large and complex system that has become entrenched. The results indicate that there are significant data retrieval problems in the AESRD routine disclosure process. As for the current study, the use of two methods of data retrieval may have minimized the loss of records. However, there is no way to ascertain, short of bringing the EMS data online, how many records were not disclosed in either the NNN or YYN queries. Therefore, the number of incidents and the analyses of incident rates should be viewed as minimum estimates of the true incident rate. As will be shown in other sections, there were other kinds of errors found in the disclosure, such as failure to release important records. The current AESRD information retrieval process does not deliver that information. The system does not provide timely and accurate data in a transparent manner (Figure 6). Delivery of all relevant requested information and confidence in the reliability and transparency of the disclosure is central to democracy and faith in government. Records retrieval and data management as practiced currently by AESRD falls below an acceptable standard for “open government.”

As practiced in Alberta, the public receives, after a significant delay, a subset of the records to which they are entitled and into which a large number of errors has been introduced. In the case of this study, with multiple queries, errors and omissions in the retrieval process were documented. Original figure courtesy of Roland Penner.

4.3 Overview of Incident Frequencies by Types The following sections tabulate the frequencies of various kinds of incidents by caller type, call type, and call reason. Because (a) some incidents apply to more than one category, (b) there is overlap in some categories (e.g., call reason “no impact” vs. “regulation/reporting” and call reason municipal vs. potable water), and (c) there is frequent misclassification of types, the frequencies of the incidents are less important than are the descriptions of the incidents themselves. The sections provide ample illustrations of the nature of the incidents, industrial impacts, and lack of enforcement, but the material presented is necessarily only a sample of the database. The reader is invited to examine the entire database. 4.3.1 By Caller Type The vast majority of incidents reported to the AESRD Environmental Management System derive from industry because industry is required to submit incident occurrences for parameters defined in regulatory approvals (Table 3). Incidents not stipulated in approvals may be reported at the discretion of the approval holder. The total of 9,262 incidents is a minimum estimate, one reason for which was that it was often unclear how many incidents were redacted and this information is not provided by government. Whenever a redacted section of a report was encountered (indicated by a blacked out area), it was assumed to be a single redaction. One “incident” in the database (from the first routine disclosure) is a compiled collection of at least 51 incidents. The number of incidents related to public complaints should not be construed as the number of public complaints. Each incident related to a public complaint may be linked to one-to-many public complaints. Table 3. Frequency of incidents by caller type, call type, and call reason. For further explanation of terms, see the glossary of EMS terms.

4.3.2 By Call Type The most frequent call types are alleged contraventions, releases, and notifications (Table 3). All three of these common call types may involve releases to air or land, exceedances of permitted emissions, notifications of plant upsets such as flaring, and other incidents. 4.3.3 By Call Reason About two-thirds of the incidents are related to air (Table 3). Incidents related to air are followed in frequency by those related to land, regulations and reporting, no impact, and surface water.

4.4 Overview of Incident Frequencies by Approval 4.4.1 Incident Frequencies by Approval Of the 9262 incidents the majority are due to two bitumen operations. These are Suncor Oil Sands (4216 incidents + 5 (10 shared with Syncrude Mildred Lake), for 4221 total incidents or 45.6 %, and Syncrude Mildred Lake (3948 incidents + 5 (10 shared with Suncor Oil Sands), for 3953 incidents or 42.7 %. Together, Suncor Oil Sands and Syncrude Mildred Lake were responsible for 88.3 % of all bitumen operation incidents over the period 1996 to July 2012 (Table 4). CNRL Horizon was responsible for 359 incidents since September 2004 or 3.9 % of the total incidents over the 1996-2012 period. Table 4. Overview of incident frequencies by Approval.

4.4.2 Incident Frequencies Over Time by Approval Overall, the total number of quarterly reported incidents increased asymptotically over the period of record from 1996 until late 2009 then declined to a rate of about 100 incidents every quarter similar to the rate observed from 1996 to 2001 (Figure 7). The overall temporal pattern of incidents is strongly-influenced by two operations. For Syncrude Mildred Lake, since mid-1996, most three-month periods have registered between 20 and 127 incidents with no clear trend over time. For Suncor Oil Sands, most three-month periods have registered between 40 and 170 incidents with a peak of 279 incidents in the final quarter of 2009. Since 2011, quarterly incidents rates at Suncor Oil Sands have ranged from 19 to 34. The temporal patterns of incident frequencies at four other operations deserve comment (Figure 8). At CNRL, since late 2004, the quarterly number of incidents has increased; since mid-2009, the quarterly incident rate has ranged from 12 to 38. At Cenovus, peak incident rates were observed during the 2003 to 2005 period soon after beginning operations; since 2006, there have been 1 to 6 incidents per quarter. At Shell Albian Sands, the quarterly incident rate has ranged between 1 and 12 incidents, with most quarters registering 1 to 7 incidents. At Shell Jackpine, the quarterly incident rate has ranged between 1 and 25 incidents with most quarters registering 1 to 9 incidents. Over the last calendar year of the data record (1 August 2011 to 31 July 2012), there were 397 incidents. In order of abundance, the operations responsible for most of the incidents were Syncrude Mildred Lake (152 incidents), CNRL Horizon (98 incidents), and Suncor Oil Sands (95 incidents).

4.5 Frequencies and Characterizations of Major Call Types The following sections document the frequency of major call types by approval and over time, then describes and comments upon a sample of the typical incidents within the major call type categories. The EMS definitions of the four most common call types (further details in Appendix 1) are as follows: Alleged Contravention = “Perceived contravention of legislation.” Impact = “Noticeable change in the environment.” Notification = “Providing of information as required by an approval or other legislation (this is not a release report or report of an impact).” Release = “Exposure of a substance to the environment that is occurring or has already occurred.”
4.5.1 Alleged Contravention Frequencies 4.5.1.1 Alleged Contraventions by Approval Syncrude Mildred Lake (46.95 %) and Suncor Oil Sands (39.65 %) are responsible for the majority (86.6 %) of the 4063 alleged contraventions (Table 5). CNRL (3.9 %) and Cenovus (2.2 %) rank third and fourth in number of alleged contraventions. 4.5.1.2 Alleged Contraventions Over Time and Approval Overall, since mid-1996, alleged contraventions have varied between 15 and 131 incidents per quarter with a mean of 62.0 contraventions per quarter or one contravention every 1.5 days (Figure 9). At Syncrude Mildred Lake, since mid-1996, alleged contraventions have varied between 7 and 91 incidents per quarter with a mean of 29.2 contraventions per quarter or one contravention every 3.1 days. At Suncor Oil Sands, since mid-1996, alleged contraventions have varied between 6 and 73 incidents per quarter with a mean of 24.6 contraventions per quarter or one contravention every 3.7 days. Temporally, overall peak rates of alleged contraventions during the period 1996 to mid2012 occurred in mid- and late-2001, early and mid-2008, and mid-2009. Peak incident rates are driven by incidents at Syncrude Mildred Lake and Suncor Oil Sands (Figure 9). There is no apparent trend in the number of alleged contraventions over time. 4.5.1.3 Alleged Contraventions by Call Reason The majority of alleged contraventions relate to air (65.4 %), followed by “no impact” (including regulation/reporting, 18.8 %), water (6.6 %), potable water (6.2 %), municipal (1.4 %), land (1.3 %), waste (0.2 %), and vegetation (0.1 %) (Table 6). A sample of the alleged contravention incidents by call reason follows.

4.5.2 Alleged Contravention Characterizations 4.5.2.1 Air Contraventions Air contraventions are exceedingly common in the data. Two companies are responsible for most of the air contraventions. These are Syncrude Mildred Lake (1368.5 incidents, or 51.5 %) and Suncor Oil Sands (1111.5, or 41.8 %), for a total of 93.3 % of all air contravention incidents. CNRL is responsible for 92 incidents or 3.5 % of the total number of air contraventions. The data suggest that, based on their consistently high frequency of incidents, some companies have difficulty remaining within their allowed emission limits. Before the focus is turned to questions of ambient air quality and environmental impacts, it is necessary to describe some of the features of the data and the incidents. Air contraventions are defined by legislation. There can be contraventions only for substances that are described in the relevant legislation; for all other releases there can be no contraventions. Thus, even if there are environmentally significant releases of naphtha, benzene, methane, PM2.5, coke dust, or other substances, those releases would not be contraventions because they are not regulated under legislation. Therefore, substances documented in air contraventions, such as SO2, NOx, and H2S, are a small subset of the total substances released. The most common air contraventions involve those of sulfur dioxide, NOx, H2S, total reduced sulfur (TRS), stack temperatures, stack opacity, and R22 refrigerant. Other types of air contraventions include hydrocarbons, volatile organic compounds, flaring (often involves sulfur dioxide), SWAG (sour water acid gas) flaring, tank venting (a chronic problem at Syncrude: see the EMS database), ammonia, particulates, and other refrigerants such as R44 and R507. Additionally, other air contraventions include exceedances of allowable downtimes (set in the approval documents) for pollution monitoring or abatement equipment such as vapour recovery unit (VRU), total vapour pressure unit, continuous emissions monitoring system (CEMS), failed relative accuracy test audit (RATA) test, and missed samples. A survey of a variety of alleged contraventions for air incidents is provided. The incidents are provided verbatim and set in blue font followed by comments follow within brackets[]. For brevity, other incident details, such as dates, are not included in the incident accounts; these can be determined by looking up the incident number in the EMS database. S02 hourly exceedance on stack -8F5 due to problem of heat incinerator. CM: S02 exceedance from 8F-5 incinerator stack (Approval limit= 3.0 te/hr) from 07:00 to 08:00 at a rate of 5.04 te/hr. Sulphur readings during the time period were 20602 ppm (20000 ppm limit). (299526, Suncor Oil Sands). [This incident illustrates a stack-specific approval limit for SO2 releases, how an exceedance may come about, and the high sulphur concentrations in the stack emissions]. Major plant emergency. CO boiler 4 tripped and rerouting tail gas lineups and therefore plant 12 (sulphur plant) got blocked in and flaring acid gas. No evacuations. Started flaring at 13:42. To mitigate situation, cutting feed rates. Emergency plan has been initiated. (453609, Syncrude Mildred Lake). [This incident illustrates a common cause of flaring-- tripping of a unit in a complex production system. It also illustrates a discrepancy in the government records. In the NNN query (section 4.1.2), the status of the incident is “pending”, 22 Aug 2012; yet in YYN query, the status is “closed”, 7 Sept 2012].
39
Significant flaring event occurring at 1350 hrs today. Caused by sulphur unit 12-3 tripping. Flaring is still ongoing. Fuel [flue?] gas recovery unit 26-1 has upset as well and there may be a potential for offsite odors. (452837, Syncrude Mildred Lake). [As in the previous example, this incident illustrates a common cause of flaring-- tripping of a unit in a complex production system, which may result in other operational upsets.] Opacity exceedance on Stack 31. Boiler #3 start up caused exceedance. (449951, Suncor Oil Sands). [Opacity of stack emissions is a measure of amount of materials such as particulates. An opacity exceedance indicates a high level of emissions.] Caller reporting a flaring notification -source flaring event produced >20 tons of S02. Flaring event began on June 23rd and ended on July 1st (unknown time). The cause is unknown -caller will include details in letter. (447306, Suncor Oil Sands). [This is a prolonged flaring event (8-9 days) of unknown cause. There is no evidence in the government records released of what caused the flaring.] Stack 1 emission exceedance for ammonia. 19:40-20:40, 1200 ppm, limit is 300 ppm. Starting up plant caused exceedance. (447233, Syncrude Mildred Lake) [The incident documents release of ammonia at a rate four times the regulatory limit.] Four incidents of the same type over an eight-day period at the same operation (Syncrude Mildred Lake): R22 release - cause unknown. It was discovered during a service call so they have isolated. It will be repaired and recharged. More details will be in the 7-day report. (440918, 2 May 2012) R22 release from HAV [HVAC?] unit, Unit 41R-157, Building 241, isolated and in process of being repaired. (441005, 3 May 2012) Release of R22, volume unknown. Repaired and is being recharged. (441489, 9 May 2012) Release of R22 from an HVAC unit, isolated and repair is scheduled. (441456, 9 May 2012), [Releases of R22 freon and other freon refrigerants are common in the EMS data. The data do not permit a total release to be calculated because often the volumes released are not specified. Releases of R22 freon are noted in 354 incidents.] 24hr rolling exceedance of S02 limit of 360 ton. Don't have any actual values at this time, will be included in the 7 day letter. Plant trip at 07:20 in 11-1C4 caused a flaring of acid gas causing the exceedance. (432648, Syncrude Mildred Lake) [The Syncrude approval for the main stack specifies an emission limit of 292 tonnes per calendar day, which appears to be the limit contravened in this case. An emission limit of 245 tonnes per day is also specified based on a 90day rolling average (Alberta Environment 2007b). The combined limit for the main stack, the MLUEP flue gas desulphurization unit stack, the five flare stacks, and the three CO boiler diverter stacks is set at 250 tonnes per day based on a 90-day rolling average.] Evacuation at the coke disposal area. There was a small fire in the waste coke pile, that caused H2S to be released. The structure units rated area at 23 ppm. The upper threshold is 15 ppm, so this caused hazmat to come out. Hazmat put water on fire area. Hazmat's readings could not match the 23 ppm and their readings were much lower. Hazmat evacuated 15 people as a precaution. Hazmat gave the all clear at 2100 hrs. No injuries to report. Cause of fire unknown, 40
fire was small. More info to come in the 7 day letter. (423632, CNRL Horizon). [Fires are fairly common in the region. Most of the fires are small, but they can release high levels of toxins due to the nature of the material being burned.] Caller reporting hourly NOx exceedances. Source is having problems with heat recovery (CoGenunit -valve that controls steam injection to burner came apart). Source is in the process of trying to repair it but they may have multiple exceedances. Caller will update AENV with the exceedance values. (415845, CNRL Horizon). [Illustrates how a single event can represent multiple exceedances. It also illustrates the sensitivity to disruption of the complex operating systems and how those disruptions can lead to exceedances.] Contravention: main stack analyzers below 90 % availability for month of June 2011. (410318, Syncrude Mildred Lake). [Excessive downtime of sensors and data recorders for emissions and pollution monitoring equipment are common. Concerns about instrument and sensor “down time”, “downtime”, “uptime” and “up time” are found in 92 incidents.] Venting from tank 7. 04:05-04:20 hydrocarbon vapors and "natural natural" [natural gas?] . SK Tank 20D-7 experiencing trips. Bitumen introduced at a rate too fast and had poor vapour recovery due to compressors unable to concentrate. Vented for 0.25 hrs. (394551, Syncrude Mildred Lake). [Venting is a common occurrence, noted in 1329 incidents, and can lead to emissions of a variety of hydrocarbons and other compounds such as H2S.] Flaring is happening due to fire & explosion. There is a NOX exceedance. Amount unknown. (391902, CNRL Horizon). [It is common for an incident to be a combination of environmentally relevant incidents. In this case, there was flaring, a fire, and an explosion. Also, “unknown” volumes of releases are common. Flaring was noted in at least 1057 incidents. ERCB (2012) recently stated it continues to be concerned with increased gas flaring and venting in relation to bitumen production. For all upstream oil and gas sources, the total volume flared in 2011 was 831 million m3, up 30.7 % from 2010 (ERCB 2012). Venting is a related process in which gases are released to the atmosphere without combustion. For all upstream oil and gas sources, the total volume vented in 2011 was 389 million m3, up 6.1 % from 2010 (ERCB 2012). The most significant source of gas venting in Alberta is that from in situ crude bitumen batteries (ERCB 2012). Recent increases in flaring and venting are related to both increased production and the low price of gas (ERCB 2012).] Odour complaint called in to caller by AENV Investigator. Public Complaint Impact Air: Smell of diesel gas - burning the throat - smell is getting stronger as caller is passing by source on highway. Vlad- reported to a very strong odour around Syncrude Energy. Follow up with Stalk holders (Suncor/Syncrude) [stakeholders] reveals both are potential contributor to the GLC [ground level concentration]. Was advised to seek medical help at the nearest clinic/hospital. (294406, Syncrude Mildred Lake). [This is an example of a health effect of poor air quality; it also illustrates a public complaint that was filed under “Industry” caller type rather than under public complaints, per se.]
41
High H2S in sour water - just received sample results from lab. Water is from flare knockout drum "19-C10-C" and will go to the effluent pond. (228019, Syncrude Mildred Lake). [Illustrates that effluent and tailings ponds are sources of air emissions.] Company does not have an approval for rotary dryer system/brine dryer stack within list of approved effluent emissions. Application was made Sept 27, 2007-was never confirmed. LM {EPO initials] Awaiting approval for rotary dryer system/brine dryer stack. Had not received approval and installed stack before written approval given. Had conducted emissions modeling, negligible results. Was given approval 15-May-09 with amendment 48408-00-03. LM triaged to MA who decided incident to be dealt with at incident level. Approvals ended up giving approval. No further action taken. (318389, Petro Canada Mackay River). [This incident illustrates an example of industry proceeding with work without regulatory approval, then being given approval after the fact with no enforcement actions taken.] H2S release C11 site glas (sour naphtha 10 barrels), clean up in progress.; Release of sour naphtha (~2000 L) - went to ground, was contained by oil/water sewer. No waterways affected Cause - broken sight glass. Isolated. Flushing to sewer. All on site. No injuries or evacs. (245838, Syncrude Mildred Lake). [Illustrates that spills can also lead to air emission contraventions. It also raises the question of what proportion of a contaminant spill to ground, in this case of 2000 L of naphtha and H2S, is captured by “cleanup” operations and what proportion escapes to the environment.] On site odour complaints. Looking for source. (245341, Syncrude Mildred Lake). [This incident is interesting for two reasons: (1) Although the incident was categorized under alleged contravention, air, the incident is an air complaint. (2) There is no evidence in the data of any “on site odour complaints” prior to this incident in which the company was looking for the source of the odour. It suggests that odour complaints were received but not recorded, which would further suggest that the number of complaint-related incidents is being underestimated.] 24 hr exceedance. VLAD [EPO initials] - 7 PPB TRS. Cloudy with low wind speed. Suncor did not record the actual wind direction and speed in their 7-day. The reason for the GLC's is largely due to the SWAG Flaring. The impacts included stations 1, 2, 11 and station 9 (Barge landing). This is a potential violation of clause 4.1.14 and possibly clause 4.1.15 of their approval #94-0200. Also incidents from the 11th -15 January are related to these GLC's (See public complaint reference # (196914 &19631). (293178, Suncor Oil Sands). [This incident illustrates a total reduced sulphur exceedance caused by flaring of sour water acid gas (SWAG) that was detected at four air monitoring stations. The EPO points out which clauses of their approval are likely in contravention.] Source has violated section 3.6.5 of Approval 94-01-21 - Clearing & Timber Salvage. Late 1999Early 2000... [redacted]...and that burnt timber was in log decks (They did haul some away). ...[redacted]...has transcripts. Source reclamation officer has stated he hid info from AENV before… [redacted]... also has info about huge unreported spills of oil and bitumen. (126411, Syncrude Mildred Lake). [This incident is troubling in several ways. (1) Syncrude reportedly burned and therefore wasted timber (hence the air contravention designation). (2) “Source reclamation officer has stated he hid info from AENV before…” suggests an admission of illegal 42
practices such as the contraventions themselves and hiding those incidents from the regulator. (3) The source reportedly had “info about huge unreported spills of oil and bitumen.” This indicates important spills of contaminants going undetected, unmonitored, and unprosecuted. (4) What did the government do to investigate? AESRD was asked to provide the status of this incident, but the Chief Information Officer declined to provide an answer. Taken together, items 1-4 suggest a systematic lack of due diligence, oversight, and enforcement. Incidents such as these undermine statements made by government that Alberta has high environmental standards and sustainable management.] 4.5.2.2 “No Impact” (Regulation/Reporting) Alleged Contraventions “No impact” (also referred to as regulation and reporting) incidents are the second-most common type of alleged contraventions. There were 764 of these incidents (18.8 %) in the record. These incidents involve failures of plant equipment, failures of pollution monitoring sensors or pollution abatement equipment, failures to meet minimum “up time” for monitoring equipment, power outages, and late reporting or failures to report. Some examples follow. Reclamation and Industrial Approvals Team Leader, AENV, advised caller they are in contravention - a mine reclamation plan was to be submitted to AENV December 31, 2004 for Mildred Lake Plant site - never RECEIVED - reason under investigation. (191568, Syncrude Mildred Lake). [The date of the incident note is 4 March 2005. Thus, Syncrude was a minimum of two months late in filing a report required under approval. It is also unknown when or if Syncrude submitted the required reclamation plan.] High TVP (total vapour pressure) on sour water tank #53D100. Sample taken this morning. Reason - ever since start-up in Sept, they have had problems keeping oil out of the sour water system. (211781, Suncor Oil Sands). [The incident indicates that from September 2005 until at least the date of the incident, 9 November 2005, Suncor was having difficulty keeping oil out of the sour water system. The incident illustrates the persistent technical difficulties faced by the bitumen operations, a common and recurrent theme in this report.] Did not achieve SO2 recovery on flue gas desulfurization unit for a 24-hr period. This is a contravention. The unit's performance is deteriorating and this contravention will probably continue until Feb 13 when they have a planned outage to address the problem. (217558, Suncor Oil Sands). [This incident illustrates that, although classified as “no impact”, this and other incidents in this category can result in excessive releases to the environment, which renders the term “no impact” misleading.] There has been a shutdown on the main coke fire boilers which has caused the refinery to shutdown. They have had flaring. Vol unknown . They anticipate more flaring during startup. They are in the process of evacuating the plant.; Provided an update on the plant shutdown/startup as well as an odour potential from startup of cokers. They are bringing the cokers on line. Will keep the extraction plant and NRU down. Upgrading water will be going straight to pond 1.; Flaring sour water acid gas because of startup of sour water stripper. The naphtha unifiner id [unifier is?] down and they are flaring to protect the amine unit from hydrocarbon carryover.; Flaring from plant shutdown; When the cokers were shutdown, 5-C-9 may have been damaged. They have put the cokers on circulation and shutdown 5-C-9. While 43
shutting down, there will be an ugly looking flaring because thick stuff will go to flare during depressurization of the unit.; Ambient H2S readings may have been caused by steaming vessels in upgrading, the extraction plant going on diluent recycle, draining vessels to the pond, sour water stripper, or the sour water pump out system. (6781, Suncor Oil Sands). [This incident illustrates several salient features. These are: (1) Operational complexity and functional linkages. (2) Unknown volumes of flared material. (3) Plant evacuation. (4) Potentially dangerous H2S emissions. (5) The classification of “regulation/reporting” for this incident obscures its significance and potential impacts. (6) The incident number, although attributed to Suncor, is listed in both the Suncor Oil Sands and Syncrude Mildred Lake routine disclosure reports released by AESRD, which demonstrates erroneous record keeping by government.] Reporting an explosion at the extraction plant. Possible HC [hydrocarbon] vapour cloud ignited. 4 people taken to hospital. Investigating cause.; Wanted update on Suncor incident.; Due to the incident at the extraction plant, sour water from the upgrading plant is being diverted to tailings pond. Odour potential. (89014, Suncor Oil Sands). [The incident illustrates an industrial accident and release of sour water to a tailings pond, both of which would be difficult to classify as simple “regulation/reporting” events.] Reporting a spill of 800-1000 litres of diesel in open pit at Aurora Mine Site. A quick coupler failed. (89271, Syncrude Mildred Lake). [Again, the incident demonstrates that some “regulation/reporting” incidents would be better classified as air, land, or water incidents. Regulation/reporting and “no impact” incidents are not necessarily harmless. No information was provided on clean-up.] Update to diverting incident. Diverting stopped at 19:05 hrs. 13 steam tubes were bypassed. Reporting opacity due to startup of CO boiler.; Update to diverting incident. Have determined that an additional 8 tubes are leaking will be extending diverting period for 24 hours.; Reporting that operations have started diverting. Expect some carry over of coke fines, producing black smoke.; Reporting a diversion due to tube leaks on CO boiler. Stack #1 will be reducing coker 81 feedrates to 75,000 barrels to reduce sulfur and coke. increase steam.; Notification that they are going to operate diverter stack this weekend. There will be lots of black smoke. They will call at the time they start and get a reference number then. The smoke will last for a few days.; Reporting ongoing co [CO] violations due to startup of CO boiler. Instrument technician was called out from town; still working on the problem. (91003, Syncrude Mildred Lake). [Regulation/reporting and “no impact” incidents are sometimes prolonged.] Continuous Emissions monitoring for NOX did not reach 90 % or January. bs [EPO initials] On-going since Dec 2007, plan to have repairs completed and re-installation of the flow rate analyzer by the end of Jan 2008. (292716, Suncor, Oil Sands, Alleged Contravention, No Impact). [The incident documents a failure to monitor emissions of NOx that had been ongoing since December 2007 and that would continue until the end of January 2008.] Waste water pond (pond C-> sampling machine is broken). Closed outfall -> water level dangerously high chances of overflow. Going to manually sample pond every 2-4 hrs. Might be repaired today but not sure. VLAD [EPO initials] -Pond C water released to the Athabasca River via pond C outfall. The overflow into the river was due to a faulty valve (60CV39/40). This is a 44
potential contravention of clause 4.2.22 of the approval. (294220, Suncor Oil Sands, Alleged Contravention, No Impact). [This closed incident illustrates an unplanned release of industrial wastewater from Suncor’s Pond C and no enforcement of a contravention. The reader should also be aware that Suncor has a license to discharge industrial wastewater from Pond C. In 2007, discharge from Suncor’s wastewater pond system was roughly 11.9 billion L (Suncor 2008a), equivalent to an annual loading of about 36.2 tonnes of metals (including tonnages of 8.6 for aluminum, 5.4 for boron, 9.1 for iron, 4.1 for strontium, 0.186 for mercury) and 6,373 tonnes of sulphate, 15.9 tonnes of oil and grease, 192 tonnes of chemical oxygen demand, and 121 tonnes of total suspended solids. These volumes and loadings are from one company’s wastewater; the current total discharge of all companies discharging wastewater and tailings seepage are unknown. Tailings adjacent to the Athabasca River constitute long-term liabilities (Figure 10).]

Figure 10. Two long-term unquantified liabilities have been incurred with the initiation of active mining and placement of Suncor’s Tailings Pond 7 adjacent to the east bank of the Athabasca River. In the same location, the long-term tendency of the Athabasca River will be to migrate eastward towards the contaminated landscape. The geological stability of this meander should be investigated. Google Earth image, 22 July 2010.
Have been disposing of coke byproduct in an area on site for the past couple of years & have not been reporting it in annual waste report. Will be in this year's report. (305280, Syncrude Mildred Lake, Alleged Contravention, No Impact). [This incident illustrates a failure of oversight by government. Syncrude Mildred Lake was disposing of coke on site “for the past couple years” and not reporting it. It illustrates that industrial self-reporting and government oversight are dysfunctional.] 3 water samples weren't collected. Cause -unknown. Samples are for mine drainage -likely required weekly -will find out. weir 1-Aug 13, McLean Cr -Aug 13, Pond R -Aug 23 were missed. (313846, Suncor Oil Sands, Alleged Contravention, No Impact). [Failure to take water samples, losing samples, and failing to report sample results are common occurrences.] Notification. Release of PCB containing oil -it just went to tailings pond. Occurred approx 1 hour ago. Caused by a contractor error. It was supposed to go offsite and contractor took it into pond. The oil will not be removed from the pond; the amount of PCB would be negligible compared to the size of the pond. (324919, Suncor Oil Sands, Alleged Contravention, No

Impact). [The incident illustrates the unauthorized dumping of hazardous chemicals into a tailings pond. Human error is one cause of unauthorized activities.] Source is re-routing excess tail gas from sulfuring unit to boilers - not going to atmosphere. Ongoing since Feb 20, 2009. No values for volumes diverted. Late report due to confusion with the wording in the approval. 15-MAR-2009 02:40 Comments: CO (4) boiler tripped and diverted notification. 14-MAR-2009 16:03 Comments: Upset in fuel boiler. Were shutting down # H-3 coker. Burner level excursion caused low oxygen in boilers 3 and 4. Had to partially divert H-3 coker boilers to atmosphere. Not quite done yet (1/2 hour yet). 2-MAR-2009 19:03 Comments: Ambient air exceedances. Picked up b/t incident location with mobile van by source. Coming from plant 25-1 which has had issues the past few days with boilers. 11-MAR-2009 16:29 Comments: New leak on CO3 boiler. Flu [flue] gas. Just informed 5 min's ago. Believe happened a couple of hours ago. Unknown rate. Plant not evacuated. Have internal people on scene now assessing. 22-JAN-2009 16:24 Industry Alleged Contravention Air Comments: All gas supposed to go to CO boiler. There is a split in ducting expansion joint. Gases going to atmosphere. Gas is SO2. Cannot estimate volumes at this point. First noticed split yesterday but when checked it today, it had grown. Working on repairs as we speak. Unsure of what caused the split. (322797, Syncrude Mildred Lake, Alleged Contravention, No Impact). [This incident illustrates how a complex production system operating at full capacity can be prone to repeated upsets. It illustrates uncertainty as to how long an upset condition has been occurring, how much contaminant has been released, and what caused the problem. The incident is troubling for four other reasons: (1) The initial statement that gases were not going to atmosphere was false. (2) The condition apparently persisted from at least 22 January to 15 March 2009. (3) There was late reporting due to “confusion.” (4) Government categorized this persistent incident as “No Impact” and did not enforce regulations even though notes by government staff referred to the incident as “Alleged Contravention”.] Missed toxicity test on Pond C. Caller thinks they missed both Feb and March. Caller has no info on why the samples were missed. Will ensure that sample for Apr is taken. TK [EPO initials] Comments: Screening bioassays where [were] completed prior to opening Pond C for 12 hours and 7 days in February and March, respectively. Formal bioassays were not completed throughout the month as the outfalls were closed over 95 % -80 % of the time. Since water was screened/tested prior to the opening of Pond C, I believe no adverse environmental impact took place. However, until the definition of 'open' is set in place, I will disagree with Suncor's request to retract the incident. No adverse environmental impact. No further action taken. Incident closed. (330239, Suncor Oil Sands, Alleged Contravention, No Impact). [This is another illustration of failure to take samples required under a company’s approval and of government’s predilection to not lay charges. There are many incidents of failure to take samples, failure to monitor emission levels of sulphur, NOx, ammonia, etc., and failure to report values or to report on time. A few examples follow.] Exceedance on the clean water discharge for the last 2 days. These exceedances were for total suspended solids. North Mine muskeg dewatering. On October 21st, 2010 at approximately 09:50 contractor sampled from North Sump discharge. Syncrude's maximum daily average for TSS is 50mg/l exceedance on the clean water discharge for the last 2 days with levels of 95 mg/l and 156 mg/l. These exceedances were for total suspended solids. North Mine muskeg 46
dewatering. Alberta Environment was notified and a seven day letter received. File closed. (385308, Syncrude Mildred Lake, Alleged Contravention, No Impact). [A seven-day letter is a weekly report from industry to government. The incident illustrates industrial loading of TSS into surface water and no enforcement.] Approval contravention: Caller told by EPO to call in failure to implement wildlife mitigation and monitoring plan. Plan currently under review. (446307, CNRL Horizon, Alleged Contravention, No Impact). [This is an illustration of failure to implement a mitigation and monitoring plan on time.] Quarter 2,3,4 of 2008; all settling ponds on site failed to have sulphate and chloride tests done due to oversight; will make correction from now on. TK [EPO initials]: Reviewed written report. Incident letter summary: Due to an oversight during analysis, the following required parameters were not tested for during the Q2, Q3 and Q4 sampling periods: Sulphate, Chloride. Sampling did not occur in Q2 2008 for the NNLL [No Net Loss Lake] settling pond as required by Table 4.2-B. TK Comments: No further action taken. Incident closed. (328856, Fort Hills Energy, Alleged Contravention, Potable Water) [This incident illustrates a failure to take required water samples for nine months indicative of lack of sufficient oversight by government. Furthermore, it illustrates a common problem with “Potable Water” call reason incidents. Many “Potable Water” incidents are misclassifications. In many cases, the call reason should have been “Surface Water” or in this case, the most appropriate call reason was probably “Regulation/Reporting” (i.e., “No Impact”). The resolution of “closed” illustrates that the government is reluctant to prosecute for failing to report.]
4.5.2.3 Water-Related Alleged Contraventions Water-related incidents are the third most common type of alleged contraventions. There were 269 such incidents (6.6 % of all alleged contraventions). Many pertain to exceedances for total suspended solids and biochemical oxygen demand in waters released to the environment. A sample of incidents follows. Similar incidents are discussed in the section of that focuses on water-related incidents. Exceedance of diluent losses to tailings pond. Cause - under investigation. CM [EPO initials]: Total volume of diluent loss to Pond 2/3 = 1406 bbl/d [barrels/day], limit is 1400 bbl/d. Decreased Plant 4 diluent recovery, high percentage of diluent in NRU feed, and two holes in the overhead line of the NRU were the reasons. (296048, Suncor Oil Sands). [This is a large volume of diluent released to a tailings pond, much of which outgases to the atmosphere. This incident could have been classified as an air contravention. No enforcement action was taken.] At an ongoing extension project, they have 4 containment ponds for surface water runoff. Due to heavy rains, the ponds started to overflow at 0900 hrs. This is ongoing although flow has been reduced over the last few hours. Suspect high TSS -don't have any readings yet; samples have been sent to the lab. Drain to Steep Bank River; not sure if this goes to Athabasca River. (305244, Suncor Oil Sands). [The incident illustrates industrial release of water high in suspended solids. Why would the writer, presumably an environmental protection officer based on the sentence structure, not know that the Steepbank River flows into the Athabasca River?] 47
Ammonia exceedance in sedimentation pond (weekly sample). Ongoing problem from earlier incident -> Nov 08. Values are trending downward from last couple weeks. TK [EPO initials]: Reviewed written report. Incident letter summary: On May 11, 2009 lab results indicated that the Ammonia level was 1.71 mg/L in Pond 6 discharge waters. Ammonia levels have dropped from 4.41 mg/L on April 27 to 1.71 mg/L on May 11. TK [EPO initials] Comments: Viewed pumps and ammonia mitigation measures at Pond 6 on June 1st. No adverse environmental impact. No further action taken. Incident closed. (332721, Shell Canada Jackpine). [The release of waters high in ammonia was an ongoing problem for weeks. A visit to the site by an EPO concluded there was no impact, yet no data were presented to support that conclusion. The volume of the discharge was not specified. No enforcement action was taken.] Water quality issue on North Steep bank. Surface runoff for disturbed land. COD limit is 200 mg/hr [mg/L?] at N.S OF 01 (Pond 1). Caller was notified today - data had been lost from April 20/09 AA [EPO initials] / reported late, exceeded COD 205 mg/L, NSE outfall 01 (NS_OF_01, release rate and duration unknown). (333467, Suncor Oil Sands). [The incident illustrates industrial loading of water high in chemical oxygen demand of unknown volume and duration to the North Steepbank River, the loss of monitoring data, late reporting, and failure to enforce regulations.] Doing an open pipeline crossing of the Tar River. This activity caused high TSS in excess of 25 mg/L above background. They are monitoring the situation and maintaining the pump flow because there is a low volume of water in the river. (245805, CNRL, Horizon). [Increasing the suspended sediment load of a river can have implications for the biota of the river, including an increase in the contaminant loading. The effects can be exacerbated during periods of low natural flows.] Exceeded BOD for June, Millennium WW Treatment Plant. Valve unknown but definitely above 25 mg/L TK [EPO initials]: Location: Suncor Waste Water Pond outfall to Athabasca River. June 2009 Incident: CBOD concentration was above approval limit of 25 mg/L (section 4.4.9 for June 2009). Cause: An investigation into this event determined that the elevated CBOD concentration is an annual seasonal phenomenon related to the pond water temperature increasing. Follow-up: A micro aeration system was installed (June 7, 2009) in the sewage treatment polishing pond. A consultant was retained to assist in developing a corrective action plan. The micro aeration system is expected to enhance bio-treatment of material in the polishing pond. TK Comments: No further action taken. Incident closed. (336108, Suncor Oil Sands). [No details were provided on the BOD concentrations nor on the total sewage released to the river. Inadequately treated sewage was released to the Athabasca River for the month of June. No enforcement actions were taken.] Continuation of TSS exceedance due to rain events. A lot of water is going through system. Khahago Creek is affected. Comments: TSS exceedance for sedimentation pond. Volume released to Khahago Creek is unknown. Cause - rain events in the recent days. TSS exceedance for sedimentation pond. Volume released to Khahago Creek is unknown. Cause - rain events in the recent days. CS [EPO initials] - TSS result from the Pond 4 discharge on June 2, 2009 was 69 mg/L, June 4, 2009 was 74 mg/L, June 25, 2009 was 48 mg/L, June 26, 2009 was 74 mg/L, 48
June 30, 2009 was 78 mg/L, in exceedance of the approval discharge limit of 25 mg/L. (336205, Shell Canada Jackpine). [The incident illustrates four features common to many incidents: (1) Released volumes are unknown. (2) Nature is attributed as the cause for releases to the environment. (3) Repeated exceedances are observed. (4) No enforcement action is taken (incident “closed”).] Exceedance - dewatering within construction site and releasing into Athabasca River. Exceedance on TSS occurred Feb 13 and lab results received Feb 14 at noon. (246132, CNRL, Horizon, Alleged Contravention, Potable Water). [This incident illustrates that construction activities, in this case dewatering, can also contribute to suspended sediment loading of the Athabasca River. It also illustrates a misclassification of the call reason; this is a surface water contravention, not a potable water contravention]. Contravention of discharge high TSS returned water from pond into the river. Sample was taken at 0809 hrs and lab result come back at 1509 hrs, pump was shut off immediately. Estimate of water discharged at 14,000 gal per minutes. CS [EPO initials] - The release of pond 4G2 water to the river began on July 16, 2009 with TSS levels below 60 mg/L. On July 21, lab results were received at 14:58 hrs indicating that TSS was 237 mg/L exceeded the limits of 100 mg/L. (338197, Suncor Oil Sands). [Release for seven hours at 14,000 gallons per minute indicates a release a high TSS water of about 5.88 million gallons. Assuming Imperial gallons, the release totals about 26.7 million L at a concentration of 237 mg/L, or a total loading of about 6,341 kg of suspended solids. No enforcement action was taken.] H2S going to effluent pond > than 472 ppm. Unit 16-1 is off spec. Troubleshooting and optimizing. Pond water is contained on site. Value was 1945 ppm. Happened @ 1100 hrs. No adverse effects at this time. (420466, Syncrude Mildred Lake). [Because this a hydrogen sulphide incident, this could also have been classified as an air incident. The statement that the pond water is contained on site is misleading in that seepage is not accounted for nor is outgassing to the atmosphere. The volume of sour water released was not specified. Sour water of 1945 ppm H2S is toxic.] Reporting an over-withdrawal on their temporary diversion licenses. They have two TDL's from the same source point. The two license numbers are 299384 and 303438. The cumulative limit on both licenses is 7240 m3 (6000 m3 and 1240 m3. They discovered today that they withdrew a cumulative total of 7287 m3 since Dec 16, 2011, which is an over-withdrawal of 47 m3. They discovered that the water truck drivers were not recording accurate volumes. They shut down the job Feb 6 for this reason. (433820, Japan Canada OS, JACOS). [If the truck drivers were not recording accurate volumes, then how does the company calculate the exceedance of 47 m3?] Caller reporting a contravention. One of their contractors removed water from a water body without the proper license. Water was removed from a wetland/marsh area. The water was used for road maintenance and service rig requirements. 23m3 were removed. (446396, Conoco Phillips Surmont) [Depending on the size of the wetland, removal of 23 m3 of water could be a significant impact. Numerous examples of contractors not following environmental guidelines are in evidence in the database.]

4.5.2.4 Potable Water Alleged Contraventions Potable water incidents pertain to failures to provide safe drinking water or to meet other terms of approvals. The “Municipal” call reason similarly pertains primarily to drinking water incidents. Such contraventions can arise for a host of reasons including mechanical and power failures, errors in procedure, and laboratory results that are submitted late, are missing, or are in exceedance of guidelines for various parameters. A number of potable water incidents appear to be misclassifications of other incident reasons such as: “Sour water release to effluent pond, higher than allowable limit. Due to unit upset on plant 16-0.” (366808, Syncrude Mildred Lake). Another example: “High diluent loss went into containment pond; potential of odour complaint; cause unknown. VLAD-Diluent losses to tailings pond 2/3 occurred over a 24hr period on March 2nd. Exceedance of allowable limit of 1400b/d was lost to the pond. There is a possible discrepancy between DCS on-line diluent loss totalizer and the final reconciled daily diluent loss result. This is a potential contravention of EP0-2007/02-NR.” Both of these incidents could have been classified under a surface water or air contravention. Other incidents suggest persistent problems at the water treatment plants, such as: May be in conflict of potable water limits. Contradiction between Cdn drinking water guideline and AENV approval. Turbidity limit is above Cdn drinking water guidelines but under approval limit. Same for THM and HHA - ongoing since approval started. CM: Limit does not have to be met until Dec. 21, 2010. (304824, Syncrude Mildred Lake). [This incident, dated 17 June 2008, documents persistent exceedances of Canadian drinking water guidelines for turbidity, trihalomethanes, and haloacetic acids that were known to the Alberta government and allowed under the lenient terms of an approval.] 4.5.2.5 Land Alleged Contraventions Some incidents within this category are misclassifications of other incident reasons, such as: “S02 hourly exceedance. Limit is 3 ton/hr, value was 4.16ton/hr for 15:00-16:00. Plant upset.” (429958, Suncor Oil Sands). Incidents in this category of contraventions document problems with industrial land management and with government oversight. Source is removing overburden and placing it into their tailings pond. Materials are supposed to be stockpiled and saved for reclamation. Caller heard that this is occurring on the night shift and not during the day which leads her to believe that they are trying to hide it. There are three areas of soil handling that could have been mistaken by lay-person as placing reclamation materials in tailings pond. – DW [EPO initials] (435759, Syncrude Mildred Lake). [It is difficult to get to the bottom of this incident because no other information is provided and the incident is “closed”. It is possible that a caller might mistake a soil handling area for a tailings pond, but this does not seem particularly likely. Secondly, if the observation that the work was being conducted only at night is true, it suggests wrong-doing. The incident was “closed” two weeks after being entered as a complaint. Other incidents, however, lend support to the view that industry is not handling reclamation materials as it should. The following four incidents are provided to illustrate.] Approval contravention. Last night, discovered digging in an area where reclamation material had not been salvaged, wasting that material. CS [EPO initials]-The new mining limits were issued, staked in the field and mining commenced, without checking the new mining limits 50
verses [versus] the reclamation salvage limits. (341102, Syncrude Mildred Lake). [Incident is “closed”; no enforcement action was taken.] Disturbance of reclaimed land - had vegetated piece of ground, reported to AENV as being revegetated and then dug a ditch through it. Area is 1.2 hectares - discovered June 10. Will stop further disturbance and will remediate area and investigate how it occurred. (334043, Syncrude Mildred Lake). [Incident is “closed”.] Contravention - wasting of reclamation material. Approval requires that the material be salvaged under approval but it ended it up being covered with 5 metres of other material so cannot be recovered. This probably occurred two days ago, but was discovered at 1500 hours May 13. CM [EPO initials]: Dump was constructed beyond limits. Area of limit exceedance is approximately 2600 m3. (301621, Syncrude Mildred Lake). [This is a dual contravention: the wastage of reclamation materials and construction of a dump beyond approval limits. The incident is “closed”.] Gravel pit - Cl [chloride] levels at 1200 mg/l sample taken yesterday - just got results. Pit is getting older - saline levels higher. Water from gravel pit goes to environment (allowed under approval). Has been stopped until further notice. (292029, Syncrude Mildred Lake, Alleged Contravention, Land). [The incident illustrates high salinity on the mined landscape and how landscape salinity may increase with time. It also illustrates release to the environment of harmful materials and that this is allowed under approval.] Failure to salvage subsoil. Investigating cause. Third party operating on the site wasted the material. They were clearing for the North mine relocation project. 120,000 m3 was mixed with normal burden waste material from below and sent it to the dump. Discovered on Tuesday, Jan 25, 2011. CS [EPO initials] -Project contactor excavated 83,000 cubic meters of good/fair upland subsoil along with underlying waste material and placed it into an overburden dump making it inaccessible for future salvage. (393617, Syncrude Mildred Lake, Alleged Contravention, Land). [This incident illustrates another kind of dump issue—a failure to salvage subsoil. This is a large volume of soil to be wasted without detection. It suggests a failure of oversight and monitoring.] Other incidents suggest soil contamination is common. As with waste-related alleged contraventions noted below, some of the contaminated sites were discovered by chance. Eleven examples follow: Preparing for construction of new sulfur plant, soil testing site which was the location of an old sour water tank - found some HC [hydrocarbon] contamination. They are working with soils group on this. (155068, Suncor Oil Sands). Have a condition on the east side of their tailings pond. Area identified as seeping from pond to ground water and was addressed in annual report and also reported to AENV in 1999 (Ref. #88583). Area was looked at this morning and noticed vegetation stress from this seepage. Investigating this. (96363, Syncrude Mildred Lake).

Found a historic contaminated site where doing an excavation by their wastewater pond system. A layer of bitumen was identified as being there a while. SETA cleaning. Still investigating source. (107784, Suncor Oil Sands). Groundwater well is overflowing water and seeping into vegetation suspect vegetation may be impacted. Sampled today - sending to lab ASAP Location-reclaimed mine area; lease 86-17. (121508, Suncor Oil Sands). Inspecting lines after last leak and suspect new leak at new location. Processed water. Thin fine tailings. Did conductivity test, found high conductivity. Investigation on-going. Excavation soon. (125756, Syncrude Mildred Lake). Reporting they were doing random sampling on the Aurora site and discovered hydrocarbons in one of their monitoring wells. They have pumped the well enough to say with confidence there was very little hydrocarbon (~10 L). They believe it may have come from a pump. (130801, Syncrude Mildred Lake). While conducting some work at the millennium upgrade site, located an UST [underground storage tank] with possible soil contamination. (57656, Suncor Oil Sands). Found contaminated soil around 34V6 HC [hydrocarbon] recovery basin, investigating, crack in system confirmed. (71681, Suncor Oil Sands). Notification of a leaking underground natural gas line on site. ATCO Gas on site, bleeding down line to make repairs. (96105, Syncrude Mildred Lake). Potential PCB spill. Old spill discovered in storage yard where old transformers are. Field test indicated >50 ppm PCB. Sending sample for analysis. Cleaning. (40742, Suncor Oil Sands). Reporting they were excavating hole for new sewer line, found gasoline and stained soil. Don't know how much area affected, spill seems to be old. Probably a buried tank. Will find out area effected [sic] and clean up. (51278, Suncor Oil Sands, Alleged Contravention, Land). [Because the EMS electronic record began in 1996, incidents that occurred during most of the years of the bitumen operations not readily available (see Methods). There have been no studies to date of hidden contamination.] 4.5.2.6 Waste-Related Alleged Contraventions Although waste-related alleged contraventions are not numerous, they are important in that they document industrial impacts that were discovered by chance. Together they suggest that were robust monitoring in place, the true number of waste-related incidents would be greater. In the context of incident data, a waste-related incident does not take place if it is not reported, and because waste incidents are not formally-monitored, their true frequency must exceed the reported frequency. Patch of used oil in ground where heavy equipment oil was changed. Looks as if it has been there [a] while. Found 2-3 weeks ago. (29006, Syncrude Mildred Lake). [How often are oil and 52
fuel spills not discovered or not reported? How much oil soaked into the ground and escaped to the environment?] Sent sand samples to lab for testing to see if hazardous. Sand is hazardous with leachable toluene. Have been disposing of 30 one gallon cans/day sand to landfill. (32705, Suncor Oil Sands). [The total amount of toluene released to the environment is not specified, nor is the amount of sand involved. How many cans of toluene were disposed of in the dump? Is a landfill an appropriate place to dispose of toluene?] Have an oily duck on the plant site. Need F&W phone number. (Closed – Referred, Suncor Oil Sands). [The number of birds oiled each year in the region is unknown.] Friday afternoon - discovered a few improperly stored drums in East mine. Contents - mixed bag. Also in this area - poorly managed run- off. They are cleaning the whole area up. (139812, Suncor Oil Sands). [The incident illustrates chance discovery of undescribed materials and also poorly managed runoff. The cleanup operation is not described. What materials were found? How much contamination remains on the site? No other information was provided.] They were excavating and found an old garbage dump full of old drums. It is not on their records. He has talked to Sadiq already. They will be dealing with it accordingly. (113368, Syncrude Mildred Lake, Alleged Contravention, Waste). [This incident was categorized under “Waste”, which is an underused category in the EMS; events of this sort are typically categorized under “Land”. This incident offers a glimpse into the hidden legacy of contamination. Like the previous oil and toluene incidents, this incident illustrates a chance discovery of industrial product drums in a garbage dump. The number of such dumps in the region is unknown. The potential for widespread hidden contamination requires study.]

No details on off site impact. CS-The Base plant Upgrader Gas Recovery Unit inadvertently caused a release of sour coker gas. The entire event lasted approx 15 to 20 minutes. The volume of gas released during the event is unknown. (350390, Suncor Oil Sands) [The incident illustrates system sensitivity to human error, the extremely toxic nature of the sour coker gas stream, and that the volume of gas released was unknown.] Fire at plant 5. Ongoing and started at midnight. Not sure of cause. Still fighting fire. No injuries. The area was evacuated; the plant was not evacuated. The EOC has been activated (Emergency Operations Centre; deciding what to do from there.). Not sure how large fire is. Not sure what 56
exactly is engulfed in flame. JC [EPO initials]; Fire at Suncor's upgrader 1, burned for approximately 51 hours and was extinguished on February 11 [2010]. A fire investigation report was produced by Suncor which included the following findings; -a gas oil line located in Plant 5 of the upgrader cracked and released hot gas oil that was above its auto ignition temperature. As the fuel source could not be isolated immediately, the fire spread to include slop oil exchanger 10E-13A and Fractionator exchangers SE59A and 5E-7B. AENV continues to work with Suncor on such emergency issues such as this fire. No further action taken by AENv at this time. (353224, Suncor Oil Sands) [The incident is a good illustration that the combination of system complexity, interconnectedness, and the processing of hazardous and flammable materials makes environmental incidents and resultant impacts essentially inevitable. The text string “AENV continues to work with [industry]” is standard script in relation to odour complaints.] They have a release of sour water. It is a constant leak, volume currently unknown. They are diluting it with fresh water currently, using the fire suppression system. They are making moves to bring the units down in order to isolate it (it is located at a common header that involves more than one unit). The area has been cordoned off. A strong sour smell is recognizable nearby. Their onsite ERP has been activated. The immediate units have been evacuated except for essential personnel. There are no injuries or other issues as a result of the release. This is in a common area called "Houston Rack". The liquid portion of the spill is contained to the site with no potential to go offsite. He has no other information at this time but will update CIC when he gets the opportunity. (431670, Syncrude Mildred Lake). [The incident again demonstrates system interconnectedness and a release of unknown volume of sour water.] Release of propane, 2200 gallons. Caller doesn't know any other information as to the cause or time of the event etc. She said there is limited staff on site so she won't be able to follow up until Monday. (441176, Suncor Oil Sands). [The incident documents a release of propane, a lack of information as to cause, and the fact that limited staff prevented a timely response. No information was provided on clean-up or mitigation.] The effluent pond is release [releasing] hydrocarbons and benzene vapours to atmosphere. Cause unknown. This was [There were] odour complaints onsite. (441749, Syncrude Mildred Lake). [The incident documents release of VOCs including benzene from a Syncrude effluent pond; both the cause and the volume of the release were not provided.] Notification required by their approval. Their "Degasser" (pollution abatement equipment) has gone down. The overhead line has failed but there is no other details known right now. This happened approximately an hour ago. There was an H2S release linked to the degasser going down. There was no adverse effects. They are not sure of the exact duration. They do not believe they are required to submit a written report (in regards to the H2S release and would like a call back from an EPO to discuss whether this is a proper assessment. (444579, CNRL Horizon) [The incident illustrates another type of equipment failure leading to increased emissions. It also demonstrates the common practice of concluding there were no adverse effects in the absence of study and without knowing the duration of the release of H2S. Finally it demonstrates a lack of knowledge by the company as to their reporting requirements. The fact that the Alberta government does little if a company fails to report or reports late provides no incentive for the companies to improve their reporting record.] 57
Flaring event on a site right. [??] Pump got tripped on high vibration and caused upset of sulphur plant. Both sulphur trains tripped due to low acid gas flow. Flaring to restore the trains. Started flaring shortly after 20:00. Still flaring. Trying to find out what is going on. Will become clear in the morning. Will call with update. Will call back with approval number. (422453, CNRL Horizon). [The incident illustrates yet another of the many causes for flaring. The incident did not provide information as to “what is going on” or when the flaring stopped. An update was not found and it is unclear what was meant that the caller will call back with approval number. In EMS parlance, an “approval number” is the approval number for the company’s operations, a number presumably known to both parties on the call.] 4.5.4.2 Releases to Land (Often as Spills) Releases to land, typically in form of spills or malfunctions of pipelines, are common in the bitumen sands region. Sufficient documentation was disclosed to suggest that spot contamination may be widespread and in need of further investigation. Spills at fuel depots are common in the EMS database. It is known from studies elsewhere that contamination of groundwater has been observed at fuel depots and there is no reason to suspect that the fuel spills in the bitumen sands region would not lead to contamination. Although the incidents reported by industry frequently state that vacuum trucks were dispatched to clean up the spills, significant unknowns remain. These are: (1) What proportion of a liquid spill is captured when the spill is into water, onto sand, or onto organic substrates? (2) How long does it take for infiltration of the liquids to prevent effective capture? (3) What liquids infiltrate the fastest? (4) What liquids bind to soil particles rendering them difficult to capture? (5) How does vegetation affect the ability to vacuum spilled material? (6) How does temperature (summer vs. winter) affect vacuum effectiveness? (7) What is the fate of the materials that are removed; what proportion is placed in dumps, presently and in the past? (8) Where are the contaminated materials dumps; are they monitored; are they leaking? (9) What is the fate of spilled materials that escape to the environment? (10) Is there monitoring of groundwater contaminant plumes at known dumps and spill sites? A selection of releases to land follows to illustrate the scope of the problem. 7500 litres diesel spilled when a vehicle drove off while refueling. Contained in bermed area. 500 litres soaked into tarsand. 7000 litres in bermed area will be vacuumed & 500 litres in tarsand will be reclaimed. (33796, Suncor Oil Sands). [This incident illustrates a typical spill. It raises the question of what proportion of a spill is captured and how much escapes to the environment. The proportion likely varies with the nature of the material spilled and the nature of the receiving materials. The question has not been studied. Incidentally, the incident also illustrates use of the term “tarsand” by industry.] He just heard about a spill of processed material that may not be in containment. Not sure if its [it’s] his company's or the site's company's responsibility to report. He has not [no] more info but will provide update ASAP.; Clarification on report #153276. Contractor would normally call it in to her company and then she would call AENV. They found hole in gypsum line at tank farm which was isolated and purged. Moved gyp. line to emergency line - now there's a problem with emerg. line so tank is overflowing - lost 3-400 gallons. Gypsum diverted to flyash pond (pond c outfall is closed) . Contained on site. This type of spill is generally nonreportable 58
because it is under 10,000 gallons and contained. Notification only. (178882, Suncor). [This incident illustrates some of the complexity of the bitumen operations. A single incident may ripple through the system. It also illustrates a lack of clarity in reporting responsibilities and lax reporting requirements (e.g., under 10,000 gals not reportable). Finally it illustrates uncertainty about the fate of the material spilled.] Reporting spill of sand & slurry from tailings line. Spill contained on site, some into buffalo pasture. (43494, Syncrude Mildred Lake). [This incidents illustrates contamination of Syncrude’s buffalo pasture. No other information was available on the spill as to its volume, chemistry, and whether any actions were taken.] At 0430 they were commissioning a portion of the intersite pipeline (between Aurora and Base Plant) A vent line was left open and they lost 1000 bbl [barrels] of bitumen to the ground at base plant. Mostly flowed into their dirty water ditch. Cleaning up now, vac truck and excavator. (127698, Syncrude Mildred Lake). [The incident illustrates a common cause of a spill—a line or valve left open by human error. It also raises the question of how much is captured when vacuuming and/or excavating a spill.] The hydro-line from Steepbank to refinery (upgrading) cracked. Quantity of bitumen & hot water spilled into east side of ditch. Product was contained. Nothing into river. 36' dia line. (79257 Suncor Oil Sands). [The writer must mean 36 inch, not feet, diameter pipeline. How much bitumen and process water was spilled? How does the writer know that all of the spill was contained, that nothing escaped? There was no follow up documentation to support the dismissal of the incident. What is the status now?] Leigh took a call from. ...earlier today.... has some questions/concerns possible gasoline contamination of an aviation site, and a possible oil spill under ice from Suncor... wants an investigator to call. (90928, Suncor Oil Sands). [This call also includes Release to Water. This call pertained to two incidents. The caller type was “in-house” (i.e. AESRD employee). There is no indication that an investigation of the two incidents was undertaken. Unless government can produce evidence that these incidents did not happen, it can be assumed that they did. Would a government employee phone these incidents into the system without reason?. An oil spill under the ice would be relatively easy to conceal and would result in unwelcome publicity and scrutiny. Therefore the incentive to conceal the incident would be great.] Spill of 2500 L caustic at train 2 slurry prep. Drain valve left partially open when filled Dec 11, 2005 hrs. Discovered Dec 13, 0210 hrs. Closed valve, neutralized spill - inside dyke. will clean in morning. Should have been discovered earlier - will investigate internally. Possibly due to many new employees – preventative details in 7-day report. Spill of 50 % caustic. Valve left open. No other details available; believe it went into ditch and eventually into their system. Contained inside dyke. (213950, Syncrude Aurora Mine). [This incident illustrates the complexity of the operation, poor training of employees, lack of critical information, and reliance on the opinion of vested interests (e.g., “believe it went into ditch”).] East tank farm -contractor was hydro testing a line - elbow failed. Release of 62000 L of glycol. No drains or waterways. Went to ditch, cleanup is underway. No injuries. No ERP activation. 59
Spill is on site. bs [EPO initials] Site inspection conducted. All contained in ditch (bermed onsite). Vac trucks on-site to haul to existing Eveready storage containment on-site. Spill result of pressure test of pipeline 200 psi, catastrophic failure (240 psi required test pressure). (295203, Suncor Oil Sands) [The incident illustrates a pipeline spill.] Spill of 200 L of hydraulic oil. Cause: from broken hose fitting on an 8000 shovel. Spilled to ground in the mine pit. Fully contained. Will excavate and take soil to their hydrocarbon contaminated soil dump. Caller is requesting a waiver. (357389, Shell Canada Jackpine). [This incident raises the question of dumps used by industry for contaminated materials such as hydrocarbon contaminated soil. How does industry prevent the escape of contaminants from these dumps in perpetuity? Does government monitor these dumps?] Spill of bitumen, ~50 barrels. Cause: had a problem with pump on one of the conveyer belts and diverted bitumen to emergency dump pond which was full already and the excess of bitumen went to side of roadway. Did not enter any waterways. Occurred on Dec 17, 2011 at 16:00. It soaked into roadway. Will dig up the dirt and dispose of it appropriately. (428363, Syncrude Mildred Lake). [This incident illustrates uncertainty as to what was done with bitumencontaminated soil.] Reporting a 250 gallons hydraulic oil spill. Cause was an o-ring fastener failure on the propel line of a shovel. Was contained on the crane pad. Sand added. Will haul to dump? (128651, Syncrude Mildred Lake). [This incident indicates that the oil-contaminated soil was hauled to a dump.] Spill of 1200 L hydraulic oil. Bleeding truck -connection tube disconnected. Spilled in mine area. Oil covered with sand - will be removed and dumped. All on site. No drains. (350255, CNRL Horizon) [This is another incident in which contaminated soil is being dumped. Where is it being dumped? ] Spill of contaminated water from tailings line, thousands of gallons so far, more to come, potential spill into Beaver Creek. South end of the lease. (244766, Syncrude Mildred Lake) [No further information was available on this spill of tailings to land and/or surface water.] Leak of Ammonium Sulphate. Due to catastrophic failure on G1 pump for plant 26-1. Was leaking 37000 gal/min for ~ 15 min, starting @ 0006 hrs [spill total of about 555,000 gallons]. Slow leak rate now. Slurry mix and no release to air. Contained on plant site and cleanup underway. (399468, Syncrude Mildred Lake) [This incident illustrates one of the many kinds of chemical spills. How much is cleaned up and how much escapes?] Caller reporting a leak from a tailings return line. A high density polyethylene line carrying recycled water with 30 MFT is leaking underground along Hwy 63. The leak is visible in the ditch. There is bubbling over the soil near a water pond. The leak is contained in the ditch. The line will need repairs. (163593, Syncrude Mildred Lake). [This incident illustrates a common source of contamination: leakage from pipelines containing tailings. How much was captured, how much escaped to the environment? What monitoring was conducted after the spill, if any, and what did the monitoring indicate?] 60
Reporting they struck oil from oil pipeline on plant, leaking HVGO, product oil. Being excavated now & will haul to landfill. Amount unknown. Valves closed on abandoned pipeline. (59249, Suncor Oil Sands). [This incident illustrates a pipeline spill of oil of unknown volume. Contaminated soil was then hauled to landfill where it may then migrate to contaminate elsewhere.] Finally, it must be remembered that incidents are often misclassified in the database and that many incidents may pertain to more than one call reason. As a result, important incidents can escape scrutiny. The following incident illustrates New contractor @ landfill not handling & operating the waste properly. Disposing of anything there. No certified landfill managers. Noticed since August its [it’s] been getting worst [worse]. CM [EPO initials]: Advised by Dean Litzenberger that it is an industrial landfill and does not require certified operators/managers. Should be inspected however because flammable/hazardous liquids are apparently being disposed of there. (315233, Suncor Oil Sands). [As with many incidents, although the information is sparse, it raises serious concerns about industrial practices and environmental unknowns. The incident documents that flammable and/or hazardous substances were being disposed of in a landfill. The incident was noted on 15 October 2008, had been ongoing since August, and the incident was closed on 23 November 2008 without enforcement action. What materials were being disposed? Why would an industrial landfill not require certified operators and managers? The incident, exposed by a public complaint and not by industrial self-reporting suggests chronic poor management practices, under-reporting, poor oversight, and lax enforcement.] Spill - boiler feed water. Unknown amount, investigating. Most caught in berm, the rest went to snow covered gravel. Vac truck used for clean up. Cs [EPO initials] -Power outage caused the steam generators to Emergency Shut Down and vent steam or blowdown to the blowdown tank causing tank to vent to atmosphere creating approx. >1m3 and exceeded allowable oil and grease values. Not sure what caused the exceedance. There is no production equipment in that area. Putting rush on other samples that were sent to lab. TK [EPO initials]: TSS and COD [chemical oxygen demand] test results were within acceptable limits. A lab error resulted in a late reporting of sample results for O&G [oil and grease]. Oil skimmers have been installed at the entrance to Pre-Sed 07. Daily inspections of pumps to be completed. Estimated Total release: 81,250,474 litres. O&G: 17mg/L (limit: 10 mg/L). (330775, Suncor Oil Sands, Alleged Contravention, Surface Water). [This appears to have been a significant pollution event, yet there is no evidence that government monitored for impacts or prosecuted the contravention. The incident is “closed”. Finally, the incident illustrates that there is little monitoring and reporting by the media of pollution events.] Effluent discharge to environment -oil and grease exceedances. Not sure of cause -> caller does not believe that these are true values. They have never has [had] exceedances before [according to caller]. Could have been misanalysis from lab. CS [EPO initials] -On 7th and 15th of May 2009, the O&G sample results exceeded Canadian Natural approval limit of 10 mg/L. The exact cause is not known but it is believed that samples were contaminated at the sampling location or at the laboratory. (335451, CNRL, Alleged Contravention, Surface Water). [The 7 May 2009 96
sample indicated 86.3 mg/L of oil and grease; the 15 May 2009 sample indicated 20.1 mg/L of oil and grease. The incident text illustrates how a contravention can be dismissed without apparent investigation. The dismissal of exceedances as due to error is common. No enforcement action was taken.] High TSS reading on north steep back [Steepbank] mine. Sedimentation pond. LM [EPO initials] Release of 23998 m3 water from outfall NS OF 03B between 14-OCT to 1320 15-OCT. TSS 110 mg/L, approval limit 100 mg/L. Outfall shut down 15-OCT 1310 when sample results were found. Consists of surface water runoff following a period of heavy rainfall. Increased turbidity levels taken in field on 14-oct were high but a decision was made not close the outfall as the TSS-turbidity relationship did not suggest a TSS exceedance. Outfall was closed within 10 mins of receiving lab results. TSS exceedance changed to 190 mg/L from 110, turbidity value changed to 180 NTU from 60, date changed to 15-OCT from 14-OCT and therefore released volume changed, section discussing decision to keep open based on ntu values and relationship removed. Spoke with Travis Kendal of Suncor 11:20 19-Nov-08 in regards to changes. Retested sample from 14-OCT, found to be under TSS limit, but 15-OCT sample was above. New volume released was 2296 m3. Call to CIC was made day after results were received and outfall closed. 10 % over approval limit for 24 hours. Should be followed up in an inspection when taken in context with prior incidents.(315291, Suncor Oil Sands, Alleged Contravention, Surface Water). [Given the volume of the discharge of water high in TSS, this event may have impacted the health of the receiving stream course. The note from the EPO that “section discussing decision to keep open based on ntu [turbidity] values and relationship removed” and “Should be followed up in an inspection when taken in context with prior incidents” suggests that industry modified a report that may have reflected on their management, and, that government had observed prior incidents that were cause for concern.] Pond E outfall oil & grease sample exceeded limit. Discharges into Athabasca river. Have closed the outfall & resampling. LM Summary: exceedance of OG on Pond E outfall of 5.8 mg/L (limit 5.0 mg/L) reported. Sample taken prior and after that sample were a max. of 0.5 mg/L. They consider the exceedance sample to be an anomaly. The outfall was temp. closed until additional samples were collected and analyzed to ensure below OG limits. Outfall reopened as sample results were 0.2 mg/L. No release occurred. OG exceedance appears to be either sample or lab error. All results after the fact and results before are consistent with the exceedance being an anomaly. (315186, Suncor, Alleged Contravention, Surface water) [This incident illustrates release of water to the Athabasca River. It also illustrates dismissal of a discharge incident as an anomaly.] Source released raw water from pond #14 into the Athabasca River. Approval stated they must sample the pond everyday if they are to release it into the river. This was not done - last sample that was analyzed was taken July 16, 2007. Another sample was taten [taken] on wed. July 25, 2007 but no analysis reports are available. Volume not known - release occurred from July 22, 2007 to 9 AM on July 24, 2007. (269788, Petro-Canada, Alleged Contravention, Surface Water) [This incident illustrates release of untested water of unknown volume to the Athabasca River by Petro-Canada. It also illustrates both failure to sample and failure to report.]

While fuelling barge, couple [coupling?] leaked under water and 50,000 litres gasoline spilled. All contained in berm area and will be pumped to the tailings area. No release. No affect to environment. (30574, Syncrude Mildred Lake, Alleged Contravention, Surface Water). [The incident raises questions. How much of the gasoline would have been captured? How can an underwater gasoline leak of 50,000 L be contained in a bermed area? How much gasoline escaped or percolated to groundwater? In what waterbody was the barge? Without testing, how can it be concluded there was no effect to environment and no release?] Raw water from utilities cooled compressor system and went into industrial sewer. The sewer could not handle the volume and the water overflowed to the sanitary sewer. All water is to go to river through Pond E. (1637, Suncor Oil Sands, Notification, Surface Water) [The incident illustrates a release to the environment of untested water of unknown volume. Pond E releases directly to the Athabasca River. Why is this a notification and not an alleged contravention or release?] Notification of possible adverse effects, Experiencing abnormally low flows coming from the polishing pond (last pond in sewage treatment). Noticed 2 days ago and thought that it was evaporation. It is still occurring so it must be something else. Suspect it could be leaking somewhere else, but still within pond system - will investigate and submit report. (172421, Suncor Oil Sands, Notification, Surface Water). [The incident illustrates system complexity, lack of competent real time monitoring and inevitability of incidents in a tightly-linked complex system running at full capacity.] H2S in water to effluent pond. Daily test. Previous sample was only 2.9 ppm. They have reduced the sour water feed and are taking extra samples (could have been a bad sample). They have been treating sour water on coker. JC [EPO initials]; On July 23, 2009 Syncrude reported fluctuations in their 8-1 Coker Sour Stream Stripper which resulted in the 8-1 Coker Stripped Sour Water [being released] to the effluent pond to be measure at 593 ppm H2S. This exceeded Syncrude's internal reporting trigger of 472 ppm H2S. Operations reduced sour water feed and then resampled. The new sample measured 2 ppm. As a result of this event at the time of the exceedance (01:00 - 3:30 hrs) there were no odour complaints or AAAQO exceedances measures at any WBEA AMS. (337309, Syncrude Mildred Lake, Alleged Contravention, Surface Water). [Again, this is a good illustration of system complexity. It also illustrates the high H2S concentrations characteristic of sour water.] Pond 3 polishing pond recorded two TSS exceedances due to an overload of surface runoff water. Pond 2 also recorded a TSS exceedance for the same reason but they will have an ongoing issue with this pond - they will release high TSS water on an ongoing basis, as discussed with AENV approvals. They would like a call back from investigator to work out something in terms of reporting. (253647, Shell Canada, Alleged Contraventions, Surface Water). [The incident illustrates a chronic problem of high TSS at this operation without evidence enforcement. It also illustrates that industry increases TSS loading to the Athabasca River.] Fish weir in Tar River blew out and caused high TSS in river. Reason: large rain storms preceding this. (269689, CNRL Horizon, Release, Surface Water). [The incident illustrates yet another means by which industry activities increase TSS loading, in this case construction of a 98
weir that later failed. Attributing the cause of the incident to rain storms or some other natural event is common in the record.] Pushing or dumping large amounts of waste into a small river or stream in area just before the barricade to the Fort Chipewyan Road. Caller didn't know name of river or creek. Going on for about a week. Call from stakeholder -waste being disposed of wrongfully. Being investigated now. Anonymous caller. Notification only. (301674, Fort Hills Energy, Notification, Surface Water). [This is a troubling incident. The fact that the EPO referred to the caller as a stakeholder and the caller type as “Industry” indicates that an anonymous tipster from industry was reporting environmentally damaging activities. Yet the incident is categorized as “Notification”, and there is no evidence of investigation. No enforcement actions took place. The resolution status is “closed”. Why was there no investigation or enforcement?] At this juncture, it is relevant to point out to the reader that the company approvals permit releases of wastewater to the environment (Tables 22, 23). Perhaps the best example is the Suncor approval (Alberta Environment 2007a), which stipulates that industrial wastewater may be released to the Athabasca River from 28 locations (Box III.). Box III. Suncor’s 28 approved locations for release of industrial wastewater and runoff to the Athabasca River “The approval holder shall only release industrial wastewater and industrial runoff to the Athabasca River watershed from the following locations, unless otherwise authorized in writing by the Director: (a) the Pond C Duckpond; [see Figure suncor ponds] (b) the Pond E Duckpond; [it is interesting that Ponds C and E are referred to as “Duckpond”[s] as both of these ponds do not provide a healthy setting for ducks; release from this pond may contain up to 5 mg/L of oil and grease] (c) Mid-Plant Drainage (Weir #10); (d) North Mine Drainage (Weir #7); (e) South Mine Drainage (Weir #1); (f) Pond R; (g) Pond A East; (h) McLean Creek Wetland Runoff Pond; (i) Steepbank Runoff Collection Ditch; (j) Millennium Runoff Collection Ditch; (k) Millennium Runoff Pond; (l) Millennium Extraction Pond; (m) Millennium Mine Gravel Pit; (n) North Steepbank Extension - Unnamed Creek outfall NS_OF_01; (o) North Steepbank Extension - Unnamed Creek outfall NS_OF_02; (p) North Steepbank Extension - Unnamed Creek outfall NS_OF_03; (q) North Steepbank Extension - outfall NS_SED_01; (r) North Steepbank Extension - outfall NS_SED_02; (s) North Steepbank Extension - outfall NS_SED_03; (t) North Steepbank Extension - outfall NS_SED_04; (u) North Steepbank Extension – outfall NS_SED_05; (v) Voyageur Upgrader Ruth Creek construction outfall; (w) Voyageur Upgrader Ruth Creek outfall; (x) Voyageur Upgrader- East Temporary Settling Pond (VU_SED_01); (y) Voyageur Upgrader - West Temporary Settling Pond (VU_SED_02); (z) Voyageur Upgrader - Permanent Sedimentation Pond (VU-SED_03); (aa) Voyageur Upgrader – East Tank Farm holding pond; and 99 (bb) Voyageur Upgrader – camp settling pond outfall.

4.7 Were All Relevant Surface Water Incidents Disclosed? Study of the surface water records raises a broader question: have all relevant surface water incidents been disclosed? The following evidence indicates that the answer is no. Missing records derive from three sources: (1) As has been documented, the AESRD routine disclosure process was characterized by high error rates. It is possible that hundreds of valid records were never produced. (2) Of the records that were produced, hundreds of incidents were redacted. When the government was asked to release previously redacted incidents that were now closed, the resultant reports produced no records that matched those criteria. Two examples of serious incidents that were not disclosed and for which no record of redaction were found, which suggest that there were more records withheld than indicated in the incident reports. And when asked how many records were redacted from the recent Syncrude disclosure, the government underestimated the number of records it had redacted. (3) Finally, valid redaction is a third source of missing records for surface water incidents, an example of which is provided from a March 2011 incident. Taken together, the evidence documents that the incidents disclosed in the database are a subset of the true number of incidents. 4.7.1 The Suncor September 2007 Incident In early September 2007, industrial wastewater was diverted to Emergency Pond D to prevent materials high in oil and grease from reaching the Pond A-B-C system. As levels rose in Pond D, pumping to Pond A began. On 8 September (reportedly due to human error),the water level of Pond D fell below the intake of the transfer pumps, at which time oil and grease and other contaminants were pumped into Pond A. Materials then flowed through Ponds B and C and into the Athabasca River. A sheen was observed on the Athabasca River below the Pond C outfall. The Pond C outfall was closed in September and remained closed until 30 January 2008 (Suncor 2008b). A total of 9.8 million L were reportedly spilled into the Athabasca River. See Figure 19. This incident was “subject of an ongoing investigation/law enforcement matter” as of 12 February 2009 (M. Aiton, AESRD, pers. comm.). Then, on 30 July 2010, Mr. Aiton (AESRD, pers. comm.) stated that “This incident is now closed and is no longer an ongoing investigation.” The incident number was given as 283162, and dated 8 September 2007. It is unclear why AESRD chose to close the incident without enforcement action. The incident is troubling for both the nature of the event and the way in which it was later handled by government and industry. The incident was revealed to the public through an anonymous tip, not by industrial self-reporting. In response to the revelation, Suncor representatives travelled to Fort Chipewyan (Suncor 2008b) and explained at a public meeting (6 May 2008, recorded on film in a documentary), that it would not happen again. It happened again (see the following “Notification” incident). Perhaps most troubling is that the incident was not disclosed during three requests for incident information (these were the first routine disclosure request (August 2008), the second routine disclosure request, which itself was two requests (the NNN and YYN types described earlier in results, August 2012), then in response to a request to release all earlier redacted incidents that were now “closed” (materials received March 2013)). That this incident was not disclosed after repeated requests and when the incident is closed suggests a contravention of freedom of information legislation. It also raises the question 102
of how many other incidents have not been disclosed. It is difficult to answer such a question because it demands knowing that the information exists before it can be determined that it was not disclosed. In the preceding incident, enquiries to AESRD staff revealed the incident number and its status. Without that information, it would not be possible to determine that the information had not been disclosed. The incident highlights a dysfunctional system of record keeping, access to information, and enforcement of environmental regulations. The related incident (noted above) follows. Notification -have closed Pond E outfall. Had high inlet sample to pond of oil and grease. Outlet to Athabasca River. Have done two more sets of samples on inlet and outlet while pond blocked in. Outlet result was one high (42 ppm and one low (0.2 ppm). Inlet result was one high (8.9 ppm and one low (0.6 ppm). No sheen on samples or pond. Closed loop pond. Could be a sample problem -still investigating. (3 February 2009, 323617, Suncor Oil Sands, Alleged Contravention, Surface Water, Resolution: Closed). It is unclear whether this incident is the same as one reported on CBC radio on 5 February 2009 in which Suncor Oil Sands reportedly spilled ~ 0.5 million L of wastewater into Athabasca River.

4.7.2 The Suncor Millennium Wastewater Incidents of September 2005 to January 2007 This is a complex set of incidents that involved release of wastewater into the Athabasca River over an extended period, failing to report violations, and provision of false or misleading information. No evidence of the incidents was found in the routine disclosures, despite the fact that the incident(s) were closed prior to the filing of the second routine disclosure. The information summarized below was found in searching old enforcement records. In brief, the incidents illustrate further examples of important environmental incidents missing from the environmental record disclosed by AESRD, illegal discharge of wastewater, failing to report, and falsification of records. The incident(s) are summarized as follows (see Table 28 for details). “On or between the 1st day of September 2005 and the 1st day of January, 2007, ... [Suncor] did contravene a term or condition of an approval, to wit: Section 5.1.2 of Approval 72754-01-00 issued for the Suncor Millennium Wastewater System with respect to the monthly arithmetic mean of daily samples for Total Suspended Solids (TSS),... On 2 April 2009 Suncor Energy Inc. ["Suncor"] and co-accused Compass Group Canada Ltd. ["Compass"] each plead [sic, pled] guilty ... This incident was related to prosecution of “Compass Group Canada (Beaver) Ltd.”, a contractor for Suncor: “Count 1: On or between the 1st day of September 2005 and the 1st day of January 2007, both dates inclusive, at or near Fort McMurray, in the Province of Alberta did contravene a term or condition of an approval, to wit: Section 2.1.1 of Approval 72754-01-00 issued with respect to the Suncor Millennium Wastewater System, which provides as follows: The approval holder shall immediately report by telephone any contravention of the terms and condition of this approval to the Director at 1-780-422-4505 by failing to report violations of section 5.1.2 of the said Approval with respect to the monthly arithmetic mean of daily samples for the parameter Total Suspended Solids (TSS), ...” Also related to this incident was the prosecution and conviction of Rodney Tyrone McCabe (and R&D McCabe Ltd.) on 12 counts related to providing false or misleading information about the Suncor Millennium Wastewater System and related facilities.” 4.7.3 The Suncor March 2011 Incident Suncor released toxic wastewaters to the Athabasca River in March 2011. The Suncor routine disclosure incident report revealed a fully redacted page in mid-late March 2011 which corresponded to this incident. The essentials of the incident are as follows (from AESRD 2013): “Whereas on March 24, 2011, Suncor reported a rainbow trout bioassay failure from a March 21 bioassay sample, when monitoring the release of industrial wastewater from the Pond C Duckpond, known as ‘Pond C’, to the Athabasca River... “Whereas the chronic toxicity bioassay test taken on March 21, 2011, also indicated chronic toxicity at 2.5 % concentration of the effluent from Pond C; [i.e., the wastewater diluted by a factor of 40 times remained toxic to rainbow trout]... “Whereas from March 21-24, 2011 industrial wastewater, which failed to meet approval limits for acute lethality toxicity testing, was released to the Athabasca River from Pond C at the Suncor Oil Sands Processing Plant and Mine north of Fort McMurray, Alberta...
105
“Whereas a number of additional bioassay tests were conducted on the Pond C wastewater treatment system, at a location in Pond C, as part of Suncor’s investigation, and thirty-nine additional bioassay failures have occurred with the discharge closed... “Whereas the source of the toxicity is still unknown, a Toxicity Identification Evaluation / Toxicity Reduction Evaluation identified the likely source of the toxicity to be a dissolved, unknown soluble organic acid compound or compounds, which may include naphthenic acids and free fatty acids... “Whereas although the dissolved air floatation [sic] improvements are effective at removing hydrocarbons using a physical removal process, the relative effectiveness of this treatment process on the soluble toxicity being observed is not known...” As a consequence, the Alberta government ordered Suncor to suspend discharge from the Pond C system, submit and implement a monitoring plan and an audit plan, and submit monthly reports. Upon acceptance of the audit plan, the suspension of discharge from the Pond C system is to be lifted. No financial penalties were levied. It is significant that an audit plan is all that is required to re-open the Pond C discharge rather than requiring that the discharge be rendered less toxic. The incident begs questions: after more than 40 years of operation, has a new toxic compound (or compounds) been found? Has the compound(s) been present for years and not detected? If it is a new compound, what is Suncor doing differently that is creating the compound?
4.8 Public Complaints 4.8.1 Complaint Frequencies It bears reiteration that the number of incidents related to complaints should not be construed as the number of complaints. Each incident may be linked to one or more complaints. The largest number of public complaints linked to a single incident was 33, associated with incident 224703, which was a period of poor air quality from 16-18 May 2006 traced to emissions from both Syncrude Mildred Lake and Suncor Oil Sands. Additionally, some public complaints are logged under the caller type “Industry” if the caller contacted industry instead of government. Because of these bookkeeping issues, the number of incidents linked to public complaints, and the total number of public complaints, are underestimated by a superficial appraisal of the data. 4.8.1.1 Complaint-Related Incidents by Approval Of the 326 incidents that involved complaints, 275 were public complaints filed directly by calling the Alberta government environmental management system and 51 complaints were filed by calling industry. Of those 51 incidents linked to industry-filed complaints, some were registered by the general public, some were registered by industrial workers, and in some incidents it is unclear whether the public or industrial workers filed the complaint. The frequency of complaint-related incidents among the company operations is stronglydominated by Syncrude Mildred Lake (59.35 %) and Suncor Oil Sands (38.45 %) who combined are responsible for 97.8 % of the 326 complaint-related incidents (Table 24).
106
4.8.1.2 Complaint-Related Incidents Over Time and by Approval Overall, between mid-1996 and mid-2012, complaint-related incidents varied between 0 and 31 incidents per quarter with a mean of 5.0 complaint-related incidents per quarter or one incident every 18.0 days (Figure 20). For complaints reported directly to government, incidents varied between 0 and 31 incidents per quarter with a mean of 4.2 complaint-related incidents per quarter or one incident every 21.4 days. For complaints reported to industry, incidents varied between 0 and 6 incidents per quarter with a mean of 0.8 complaint-related incidents per quarter or one incident every 112.5 days. At Syncrude Mildred Lake, between mid-1996 and mid-2012, complaint-related incidents varied between 0 and 15 incidents per quarter with a mean of 2.9 complaint-related incidents per quarter or one incident every 31.0 days. At Suncor Oil Sands, between mid-1996 and mid-2012, complaint-related incidents varied between 0 and 16 incidents per quarter with a mean of 1.9 complaint-related incidents per quarter or one l incident every 47.4 days. Temporally, the number of complaint-related incidents peaked during the period 2006 through early 2011 (Figure 20). The frequency of complaint-related incidents varied widely from over time. Complaints reported to industry peaked from 2006 to 2008. Complaints reported to government peaked from mid-2006 through early-2011. The quarterly frequency of complaints reported to government was not correlated significantly with that of complaints reported to industry (Spearman r = 0.23, df = 64, p>0.1).

4.8.2 Characterization of the Complaints The incident number, date, company responsible, call type, call reason, incident status, and incident particulars of the 326 complaint-related incidents (Table 25) provide insight into the history of environmental management in the region. The table documents a host of public concerns. This section highlights some of the incidents to explore the relationships between people, the bitumen industry, and government. In an Alberta-wide study of 12,452 incidents in the EMS database registered between January 1996 and September 2002, Eckert (2006) observed that the frequency of public complaints differed between industrial sectors. Public complaint-related incidents about the food and beverage industry comprised 49.2 % of all public complaint incidents in the province and 63.7 % of all incidents within the food and beverage industry. For the oil and gas sector, province-wide, public complaint-related incidents comprised only 1.3 % of all incidents within the oil and gas industry. In comparison, in this study the proportion of complaint-related incidents to all incidents within the bitumen sands operations was 3.0 % for public complaints and 3.5 % for all complaint-related incidents. This finding suggests that complaints about the bitumen industry occur about two and one-half times more frequently than they do for the oil and gas industry overall in Alberta. Most of the complaints are related to air. It is relevant to ask if the frequency of airrelated complaints is related to the frequency of air incidents. Of the 6,013 air incidents, the vast majority are air quality events, such as 2,657 alleged contraventions, 1,685 releases, 1,445 notifications, and 208 impacts for a total 5,995 or 99.7 % of all air incidents. The frequency of air incidents over time is correlated with several measures of the number of complaints (Table 26, Figure 21), demonstrating that complaints are a reliable measure of air quality and are not simply nuisance calls. The relationship between the quarterly frequencies of air incidents and complaint-related incidents, although significant (r = 0.565, p 1 call type for the >1 calls pertaining to the incident. Under call reason, a semicolon indicates >1 reason for the >1 calls pertaining to the incident. Under comments, a semicolon that immediately follows a period denotes a new set of comments (typically a separate complaint) pertaining to the same incident. Comments by the authors are set in square brackets. Incidents informative of air quality concerns are set in blue font. Approval 94

Odour started around 2000... was in the gym and could smell the odour through the vents. Tarsand odour. Noticed an awful odour about 20 minutes ago. There is an oilsands odour in the air which... thinks is coming from Suncor. lt has been present for about an hour. It smells very bad today. It started this morning & I thought it would go away. Plant smells... smelled it as... drove by this morning. The stacks are "just a·going." The odour is almost enough to bring tears to the eyes. [Information removed] There is an incredible odour from the plant this morning. It is unbearable. It is particularly terrible at Finney. Just noticed a bad smell in the air this morning. Smells like tar, the plants. Odour is coming from plants. Cannot describe smell. Strong odour of oil sands. There is a strong odour north of the oil sands plants [this is evidently a public complaint that was coded under "agency" caller type] Caller is doing work at the plant and noticed oil has been sprayed for dust suppression. The oil is splashing on his vehicle. Caller has concerns about the amount of oil/hydrocarbon that company puts into tailing ponds. Can see a brownish/grey cloud coming from plant and wonders what it is. Winds blowing SE. Blue haze is coming from the stack and heading toward town. Diverter stack will be down for repairs due to boiler tube leak. Odour potential.; Concerned about black smoke from plant stack since morning. Flaring ammonia gas.

Due to the shutdown, there are several contraventions to report. They had a low stack temp; an SO2 violation on incinerator stack and an odour from north tank farm.; Update to Suncor incident, planned shutdown delayed due to continuing plant upsets during shutdown; odour potential.; Air quality complaint; believes the source is Suncor. Smells like their stack emissions, burnt odour.; Ambient air contravention from station 5 Mannix.; Opacity contravention, black smoke due to the loss of a boiler during shutdown.; Strong odours in the area.; Odour complaints; has been noticeable since Monday and is now more apparent in the downtown area. There is black dust blowing from the pond to the highway. It is so dense that it is difficult to see through. Called to say... was driving by Syncrude tailings ponds and the smell is very strong...wanted to report... Caller complaining of poisonous yellow gas coming from Syncrude,… [redacted] There is a strong wind in the area, and it is blowing dust off the source tailing pond. It is very difficult to even see the road in the area. Strong winds are blowing dust off sources tailings pond dyke across the road. Reporting a sewage release from a broken line at building B-792 in mine. Approx. 50 gallons released. Complaining about odours north of source. Noticed night before also. Could be from tank venting. Caller complaining of brown plume from Syncrude, visible from town migrating east of town.; Checked plume, did observe some colour; yellow-green colour. Checked with utilities, no problems; incinerate ammonia from sour water stripper. 2 deg C increase in stack temp. Details in earlier incident. Caller reporting a strong foul odour from source. Similar to the one he reported yesterday. It's coming from a source pond. Reporting H2S smell as she was driving north past Syncrude gate. Wants to know if there is anything going on. Very strong sour gas smell on the highway at the Syncrude gate. Odour complaint, caller believes odours coming from sour water tanks. Strong odour coming from source this morning @ ~ 08:50. Strong onion smell from source on Saturday . It was a problem prior to that as well. 18000 litre tank of propane being burned off at Muskeg River Mine site due to valve being stuck open while unloading.; Reporting burning propane tank. Upset about how things were handled as far as ER [emergency response] and evacuations etc.; Received more info at 11:50 on the propane tank that was burning. Fire was extinguished at 18:00 March 18th. The water used formed ice and put it out. At 0700 March 19, they received a 3 " flange that will allow them to transfer the remaining propane (~12,000L; 66 %). Difficulty connecting the flange. Expect transfer to take 4-6 hours, once they get it started. Will flare off the remaining vapours. Two ICG Propane Experts from Edmonton are on-site. A Workplace Health and Safety Rep also on-site. See call sheet for Albian... Update. Albian Sands propane truck issue is still unresolved. Could not offload product because coupler is damaged. Still assessing options. No action will be undertaken tonight.; Update on propane fire. Incident is now over. Last night at 22:00, they decided to transfer the rest of the product out of the tank, instead of moving the tank itself. This went from 22:00 to 01:30 this morning.

Closed Two complaints -first complaint: driving into Fort McMurray from the north and noticed large fire with black smoke plume on Source site -in the steep bank mine area across river from Upgrader. Wind is north so plume heading towards town to the south. Vlad-This incident is related to the public complaint 202803.; Comments: Approximately one hour ago they had a fire start on a mine haul truck. They weren't able to extinguish it; letting it burn itself out. There were no injuries. Heavy bitumen on the truck. Not sure how it started. Closed Received anonymous complaint from former employee.

Followed up with shift supervisor at Syncrude, asked for a manual stack survey to be completed. Results came back as nothing, in normal operation. Issue is ongoing, Barb Saunders is looking further into the ammonium stack issues at Syncrude. AENV continues to monitor. Odour complaint. Very strong sulphur rotten egg smell. No idea where it is coming from exactly. JC; From 9:00-10:00 hrs on August 17, 2009 there was an exceedance at AMS 2 measuring 62 ppb (incident 215674). At around that same time a Fort McKay resident called in with an odour complaint of rotten egg sulphury smell. This was the second complaint received within the hour. The Odour protocol was enacted and Syncrude, Suncor, CNRL, and Shell Albian were contacted. Based on the 62 ppb, 147 degree and wind speed of 10 km/h at the time of the complaint, it is probable that the source was Suncor. AENV continues to work with Suncor on these exceedance issues. [Standard script] Odour of sulphur smell (rotten egg smell) very strong now. JC; complainant calling in indicated that he smells an odor of sulphur (rotten egg smell near Suncor) (Hwy 63 North bound). Odor protocol still in effect. Message left for Dan to check updates on the WBEA information line. Wind direction at the time of the complaint indicates Suncor as the probable source.

Spoke to the complainant on another odour complaint (ref 239531) and she indicated that she smelt ammonia at 15:30 hrs, August 24, 2010. A review of WBEA data shows no exceedances at the time of the complaint but at AMS 2 wind direction was 199 degrees, 10.65 km/hr which would indicate Syncrude is the probable source for the ammonia odour. JC spoke to CIC and the call sheet was re-sent the following day. AENV is working with the public and industry on such odour events and will

continue to monitor them as they arise. [Standard script] Caller reporting hydrocarbon odour. Very strong between the tailings ponds (7 out of 10, now that caller is at work the odour is a 5 out of 10 but may get worse. JC; spoke to Karla Buffalo member of the public/Fort McKay IRC regarding her complaint. AMS 2 exceedance (239485) recorded at 19ppb 143 degrees. Spoke to Sylvie Harper of Suncor, no flaring, venting events occuring and upgrader is on spec. Based on information we know and wind direction, probable source is Suncor Ponds. AENV is working with Suncor on the issues and will continue to monitor odour events as they occur in the region. No further action taken on this particular issue at this time. [Standard script] Odour, hydrocarbon. Caller noticed the odour this morning. Continuous strong hydrocarbon odour. Light breeze in the area. JC; left a message for Doris Lacorde a member of the public from Fort McKay to call me back regarding the hydrocarbon odour complaint. Ref 239485 Stn 2 exceedance of 19 ppb 143 degrees which would indicate Suncor as the probable source. Very strong odour in the area. Caller had to turn off AC because she's had a coughing fit and is concerned about coworkers working outside. Clear day and light wind .... caller believes the odour is coming from the north. JC; Called the complainant and left a message. No call back was received. At the time of the complaint according to AMS 2 the wind direction was 83 degrees at 10.85 km/hr. This would indicated that Suncor Ponds are the probable source for the odours. AENV continues to work with Suncor on their pond issues but no further action regarding this incident at this time. Odour at Hwy 63, north of Source. Mixture of hydrocarbon and gas. Strongest at 4-5 km north of where the Hwy turns into a single lane. (Level 3) Odours on Hwy 63 - likely from source. Ammonia smell. Just north of the tailings ponds as the highway turns into a single lane heading north. It is a 4 on a scale of 1-10. She would like a call back from an EPO. (Level 3) Odour -oil sands and plant smell -noticed this morning when caller woke up and it is still lingering. Smell is worse than normal as it is raining and the smell is lingering. JC; Odour complaint in the city of Fort McMurray. There was an H2S exceedance measuring 10 ppb from AMS 5 at 359 degrees. Probable source is Suncor ponds. Caller did not like a call back so one was not given. Strong odours of hydrocarbon and sulphur from Source. He is currently driving 2 km south of Source entrance. (Level 3) JC; At the time of the odour complaint a AMS 5 exceedance Ref 239930 was noted. 12.5 ppb, 39.44 degrees wind speed 1.77 km/hr. At the time of the exceedance and complaint Suncor reported a flaring event which is most likely attributing [contributing?] to the exceedance and complaint. A message was left with Dr. John O'Connor's administrative assistant and the information was taken down as he was unavailable at the time to talk. Smelling THC in the air. They have just noticed it. Two kilometers from Fort McKay. On Hwy 63 north. Bad enough for her to call AENV. SK-KEARNEY phoned CN back to discuss. Source likely Suncor Ponds Received odour complaint from resident. There is a plume leaving source, leaving a foggy smokey haze - causing visibility issues on Hwy 63, stinks. CS-As per the WBEA website SO2 was 13.17ppb, H2S 2.03 ppb and THC 2.40 ppb. Smelling Total Hydrocarbons in Fort McKay. JC; spoke to the complainant. At the time of the complaint there was an H2S exceedance of 17 ppb at AMS 11 165 degrees. Probable source would be the Suncor Tailings Pond. Caller worked for a company that released refrigeration gases out of their service trucks from the recovery bottles. They also do not log and report releases. This company has a contract for a major plant. He feels that our legislation is not tight enough on refrigerant releases - not so much as the rest of Canada. JC; follow-up to allegations of an R22 release into the atmosphere from Aircon Technologies, email to Brooke Bennet and John Ellingsen of Syncrude. Internal investigation showed that the company does report its releases and their log of repairs. The quantities in the log are fairly low totals of between 3 and 5 lbs. The allegations are most likloy [sic] from a discruntalled [sic] employee. Syncrude and Aircon Technoligies [sic] took these allegations very seriously and could not find any truth into [sic] the allegations. [Selfinvestigation] Thousand litre of naphtha spilled 3 weeks ago from a line break, contaminated dirt and snow was put into the bins and still on the site. Some of the spill is still on the ground and was not cleanup properly. He just checked his phone messages and had received an odour complaint from 19:00 hours Jan 15. This was near source, on Hwy 63 northbound. The location is near Beaver Creek and on the east side of the plant site. The odour was not the usual odours they get -it is described as hydrocarbon / fuel odour. He would like a call back tomorrow after 8 am. (level 3). Odour complaint. Hydrocarbon smell, ongoing. bs at time of call, no industry upsets received. However late reporting Suncor valve open since Dec 28/10, sour gas emitting. [Valve left open for three weeks] Odour complaint smells like sulphur and hydrocarbon. More so sulphur. In Timberly and Dickensfield area. Score of 1-10 this is 5 or 6. This is a nuisance smell. Would like a call back. Odour complaint, noticed odour at 16:15. Sulphur and ammonia odour. Odour complaint. Started at 4:00am. Terrible smell. Industrial smell -Sulfur/onion odour.

Odour potential notification. Emergency tailings tank vent popping open for 1 minute several times during the day. They cannot stop it because of the tank design and the pressure build-up. Odour complaints will consist of hydrocarbon. [Illustrates the difficulty of preventing incidents] Odour potential due to maintenance on outage on NRU; checked around plant site. Nothing unusual. Had a lightning strike in the SW mine area which caused a compressor to trip, resulting in some flaring of hydrogen.; There is a very bad odour from tarsands projects.; Can smell the ponds while driving down highway past the plant turnoff. Wind is from NW.; Confirmed there is an odour. Will check plant operations and ambient stations.; Complaining about odour coming from ponds.; Ambient H2S reading due to naphtha in tailings pond. NRU is down at Suncor.; Ambient H2S reading caused by NRU being down. Readings are still high. Follow up from odour complaint. A transfer from one tank to another of untreated naphtha and flow agitated the material and caused it to vent. Update to public complaint regarding NH3 odours. Conducted ambient monitoring between gate and Buffalo view point, all ok. In response to the odour complaint. Calm winds and hazy conditions. Will check the plant status.; Checked the stations. Had a peak on HC at 14: 00 hrs. at Buffalo Viewpoint otherwise nothing. No plant upsets. Really smoky flare - not sure why. May be due to start-up of a train happening this week. Will call back with any major details, minor details in follow up letter. May get public complaints.; Had another smoky flare for about 10 min at 1630. Had liquid run down sides of flare and catch fire. Fire team went out. Still investigating into problem.; Update - cleaning out system with nat. gas - flushing flare lines - blower is damaged so there may be smoke with opacity just over 40 % can not see from Hwy. May need to keep going though night. AD suggested he update ref# 141833. Regarding odour complaint - did not find any unusual plant operations - however caller and AD agree Source of odours may be the source pond. Complainant was also concerned with brown haze in area not sure of cause but they are experiencing higher levels of NOx and SO2. He is confident in these readings since they are currently conducting a stack survey. Investigating. They have isolated the leaking line and will repair before being used again. (CEPA reportable).; [Redacted] ...wants to complain about own company creating off site odour from sour water tanks. {Redacted] ... noticed it as [redacted] bus pulled up to the site this morning.

Odour complaint on site. Think it is from draining down a section line from plant 13-2 for psvao removal. One of their employees complained of an onsite odour at 1650 hrs. The odour of ammonia correlates to an ammonia truck which was unloading at the time causing intermittent odours. Odour complaint from a worker. Strong hydrocarbon odour. Area 41Y. They are investigating. [Incident unrelated to another 41Y worker odour complaint (incident 68893)] Caller received notice of odour complaint from AENV investigator. Flaring acid gas. Unit instability. Not contravention as of yet, just a notification. Vlad- Various plants upsets caused by 11-1 and 11-2 plant Amine Treaters process upset and subsequent multiple plants flaring that occurred on the 29th of January, 2008. Syncrude did not exceed the SO2 limits, no odour complaints. However there were 4 Alberta Ambient Air Quality Objective exceedances that resulted from the flaring and plant diverting events. This is a potential contravention of clause 4.1.16 Table 4 .1A and 4.1.1 Odour complaint called in to caller by AENV Investigator. 01-FEB-2008 00:08 Smell of diesel gas - burning the throat smell is getting stronger as caller is passing by source on highway. vlad- Reported a very strong odour around Syncrude Energy. Follow up with Stalk holders (Suncor/Syncrude) [stakeholders] reveals both are potential contributor to the GLC [ground level concentration]. Was advised to seek medical help at the nearest clinic/hospital. [Incident unrelated to another diesel incident complaint (incident 229087)] AENV had called him regarding an odour complaint. He has no info on whether they are responsible but will update when he gets more info. High diluent loss went into containment pond; potential of odour complaint; cause unknown. VLAD-Diluent losses to tailings pond 2/3 occurred over a 24 hr period on March 2nd. Exceedance of allowable limit of 1400b/d was lost to the pond. There is a possible discrepancy between DCS on-line diluent loss totalizer and the final reconciled daily diluent loss result. This is a potential contravention of EP0-2007/02-NR Investigating odour complaint. ...Does not think it is coming from their plant but they will look into it.
Tank venting. Hydrocarbon vapour from diluted bitumen tank. Not sour. Feed rate into tank was high. 3 times: 1409-1540 hrs, 1644-1724, 1811-1826. Problem now solved. CM: Between 14:09 on June 14th and 4:58 on June 15th, Tank 20D-2 vented N, HC's, and S compounds intermittently for a total of 5 hours. Reason was a sudden influx of hot dilbit into 200-2. 1 Odour complaint (Ref 202780) can be attributed to this incident. Acid gas flaring. Blower tripped on Plant 12-3. Started high, ended low. Acid gas flaring. Blower tripped on Plant 12-3. Started high, ended low. V0-Possibly linked to the public complaint # 205403. The wind speed was relatively calm at 75 m elevation, meaning the acid flaring could be the source of the public complaints.

Venting from VRU -hydrocarbons. VL-Probably linked to public complaints (204945) LM Stage 2 of VRU offline 03:58 to 04:00 19-Aug, Stage 1 vented intermittently 12:19 to 13:13 19-Aug. Stage 2 offline 2 minutes, flow rate of vapour untreated was 1100 SCFM, stage 1 PSV lifted intermittently for 53 min. Vapours released contained light end HC, VOCs and treated process vapours (treated for H2S). Unknown cause of Stage 2 trip, possible low-temperature trip causing refrigerant compressors to trip. Stage 1 result of process gas outlet piping of refrigerant coolers in stage 2 freezing, resulting in higher pressure drop across stage 2. The increased pressure at the outlet of Stage 1 to above PSV set point. HVAC personnel responded and troubleshot problems. "Operations and HVAC personnel will work towards improving VRU Stage 2 operation". If continuing issue an inspection should be planned by AENV. Tank Venting on the weekend -20D-2 Tank -Diluted bitumen. LM Summary: 3 tank venting events over 3 days, total of 501 minutes from 20D-2 tank PVRV in south tank farm. Tank contains diluted bitumen, vapour released contains light hydrocarbons and assorted sulphur compounds. When managing incoming diluted bitumen, operators diverted portion of fresh DB to stagnant 20D-2, influx of hot DB caused pressure in tank to increase. Most vapours treated via VRU, but excess pressure caused opening and release from PVRV. 25th incident result of malfunctioning pressure control. When venting noticed, DB inflow was adjusted and on 25th corrected malfunctioning valve. No odour complaints received 26 and 27th Aug. No further action at this time. Future inspection RE: tank venting to be considered. [Event illustrates that a prolonged venting event may not result in public complaints] Tank Venting from #D7. Maximized Vapour Recovery Unit. LM Summary: venting from bitumen tank 20D-7 03:55 to 10:00 of natural gas and hydrocarbon vapours. High rundown rates to the tank, a missed alarm and high pressure were the cause for the incident. Operational moves decreased the extraction rundown rates. Several odour complaints were received during and after this time frame, but are thought to be associated with the diverting incident at Syncrude that occurred during and after this incident. No further action taken at this time. High turbidity on potable water at building 160. The sample was taken today at 15:00 hours. The reading 13 NTU, but she does not know the approval limit. A complaint was received about discoloured water in a toilet. Actions taken: sampled and flushed the lines. Signs were hung to notify users to not use water and to leave the taps on for flushing.

Table 26. Correlation (Spearman) between number of quarterly complaints and air incidents (66 year quarters, 65 df). Correlation with Quarterly Air Incidents (r, p) Total Complaints 0.614, p diluted bitumen tank. Hydrocarbon vapours , some sulfur compounds. Cause unknown. CM [EPO initials]: Tank 3 vented N, HC, and H2S for 31 minutes. 22 September 2009. Ambient air exceedance. [This type of incident comment is common. Incident details may provide contaminant concentrations, but there is no explanation as to how the incident occurred nor at what air monitoring station the exceedance was observed.] 23 September 2009. Hydrogen sulfide, sulfur dioxide smell. Caller can see that industry is flaring. 4.10.3.3 Salient Features Taken together, the incidents illustrate several salient features. These are: exceedances are often of unknown cause; there is a concern expressed by EPOs as to whether there were complaints associated with the incidents; when causes are identified, they are diverse; H2S incidents are common and chronic; Alberta Environment relies upon industry to investigate and provide further information (it does minimal verification); Alberta Environment tacitly permits the exceedances by failing to take enforcement actions. Exceedances to air for H2S, TRS, and SO2 are common at Suncor. They are seldom tracked to a particular source within the operation. The incidents illustrate an obvious fact that bears stating: the number of contravention incidents in the EMS data is a subset of the number of air contraventions recorded at the air monitoring stations. For example, for hydrogen sulphide at four monitoring stations over the period of record, there were 3363 hourly air exceedances, which translates to 62.6 incidents per year at each of the four stations or roughly 250 exceedances for hydrogen sulphide each year at the four air monitoring stations. Inspection of the EMS records during period covered by the AMS data (1998-2012) indicates 227 alleged air contravention incidents attributed to H2S. Relative to the number of hourly exceedances at the four AMS during that period (n = 3363), the combined data suggest that the true incident rate for H2S exceedances may be approximately 14.8 times higher than the rate indicated in the EMS data.

4.10.4 Total Hydrocarbons (THC) The chemistry of total hydrocarbons in air is complex. In order to gain a better understanding of the total hydrocarbon concentrations in the region, the data should be corrected for the global background concentration of total hydrocarbons, in particular for methane, the dominant component of total hydrocarbons in the atmosphere. The global background concentration of methane varies by latitude and season and has been rising over time (I. Simpson, University of California at Irvine, pers. comm. 19 April 2013). Because global background values are variable and increasing over time, and some relevant data on global values are not available, it is not possible to adjust the total hydrocarbon values at the air monitoring stations with a high degree of precision. Therefore, in order to provide a rough approximation of the global background, an average global background comparison of 1.849 ppm was applied (Appendix 3: Table 4; total hydrocarbon concentration is dominated by methane; near the ground, roughly 99.6 % was attributable to methane in the data gathered in the study region). When this approximate global background value is used as a threshold for the THC measurements at the 14 air monitoring stations, the data indicate that THC concentrations lie above the background concentration about 62-97 % of the time. A portion of the elevated THC concentrations would be due to local industrially-produced methane such as outgassing from tailings ponds. Holowenko et al. (2000), for example, estimated that the equivalent methane production of 500,000 cattle/day is emitted from Syncrude’s Mildred Lake Settling Basin. Methanogenic bacteria are thought to anaerobically degrade components of naphtha, e.g., toluene, xylenes, and C6-C10 n-alkanes, into methane at rates of up to 40 million L methane per day (Simpson et al. 2010). The temporal pattern of elevated THC concentrations at two air monitoring stations is illustrated in Figure 29. Examples follow of incidents that involved releases of hydrocarbons in relation to periods during which station exceedances were observed. 4.10.4.1 Incidents, Mid-December 2006 to early January 2007 (AMS 12) Syncrude Incidents 18 December 2006. Venting from tank D-33 (light gas oil). Not sure of cause. Vented from 1716-1724 hrs. will include more info in written report if they find out more. 19 December 2006. Brief tank venting HC vapour. Occurred ~1 hr ago, duration was ~5 min. Cause likely run down rate and temp. No other details available. 19 December 2006. Venting of NRU unit, Plant 6.

Coker gas is being flared and may exceed 20 ton SO2 limit. Periods with elevated THC concentrations were frequent at AMS 12 over the period from late December 2007 through 2012. One such period is considered below as an example. It is unknown whether the incidents listed below were the direct causes of the elevated THC concentrations at AMS 12, but such incidents would have elevated the THC concentrations in air. 4.10.4.2 Incidents, 12 December 2007 to 8 January 2008 (AMS 12) Syncrude Incidents 12 December 2007. Tank venting - > sour/hydrocarbons. Still venting, taking steps to stop. Plant upset some units down. 12 December 2007. Tank venting (tank #13) hydrocarbon vapours. Switched to another tank to stop it and also detuned the product in tank. 14 December 2007. Tank D13 venting hydrocarbon vapour. Reason: slopping volatile product. 22 December 2007. Venting from D-53 (dry bitumen tank). Started at 1303 hrs and is ongoing. Tank contains hydrocarbon vapour which is likely not sour. Cause - offgas vapour recovery system tripped. Currently trying to restart. Suncor Incidents 18 December 2007. SRU #3 and 4 are down on upgrader # U2. Flaring swag (sour water acid gas) from upgrader. Not related to flaring at U1.

Reporting flaring of over 20 tons Dec 1-2. Trip on SRU #4 on high level reading in knockout drum, was the cause. Initially was not reported because valves were only partially open. They exceeded their limit of SO2 released in a 24-hour period. (Limit - 360 tons - flaring + venting). Exceedance was from midnight Dec 3 to midnight (00:00) Dec 4. They had some minor venting this morning from tank 20-D-4. The cold weather caused a blip on new instruments. They have a potential to flare over 20 tons of SO2. flaring began Dec 3, at 1931. Ongoing. Cause is that the valve is now open continuously. Reporting a sour water leak at plant 13-2, the naphtha hydrotreater line froze and split. Operators flushed waste into oily water sewer, ends up in effluent pond. will be bringing the hydrotreater #2 up; therefore will be flaring butane during start up.

Regulation/ At 0700 they had a leak on their gypsum line from the flue gas desulfurization plant. Approx 200-300 gallons Reporting per minute entered the waste water pond system which is closed to river. They shut down the line from the gypsum the gypsum tank which overflowed approx 30000 gallons of gypsum into the coke pit area. Some has frozen and some flowed with the waste water pond system. This was their best choice. Additionally 15-20 employees were exposed to upgrader oily mist (a He chemical), source unknown, and went to first-aid area. Municipal High turbidity in potable water distribution system. Plant 86 (Millennium Extractor). Cause - a leak in the piping system meant shutting down for repairs. Fixed leak - but while starting up, stirred up debris. Flushing system currently, testing turbidity every 30 min until within limits. Regulation/ Flow meter 19FT-36 was becoming unreliable so it was removed from service between 1500 and 1610. Reporting Regulation/ Gypsum line leaking - have to bring down FDG to fix.

Municipal Notification - have to meet 100 mg/L TSS-hasn't been confirmed. will call back once confirmed. Upset in sulfur unit - resulted in flaring. K48 compressor problems caused sulfur recovery unit #2 to trip. There is still flaring. They are working at getting another sulfur unit going. There is a potential for an exceedance. Sewage pond bleach containment. Amount spill unknown yet. Did not spill into river. Fax in to notify of flaring excess fuel gas, will end once boiler is brought back into service. Cloudy sky; colour spread out; not near stack; probably due to weather and regional contribution. Refrigerant leak 13 kg from unit 13-1. Details to follow (type of refrigerant, cause). Heavy hauler on site. Ground is soft because of rain. Heavy hauler bottomed out and took fuel tank out of vehicle. Contained on ground. Sandy soil, but will introduce more sand then clean up. One tank venting #13. Venting sour naphtha/hydrocarbon vapour. Swung tank to stop venting. Tank venting from tank D100. Investigating as to why it happened. Tank venting on tank #13 (naphtha). Suspect its been going on for ~3 hrs (tracking odour). Major trip on plant 9-4 may be the cause; entire system was backed up.

The caller reported that a pipeline ruptured and spilled a coke and water mixture on the ground. All was contained in the oily water sewer system. None left the facility. No waterways were affected. Partially treated sewage spill. Routine maintenance on two train unit - a hose broke on vacuum truck contained (absorbed into ground). Drained into ditch leading to recycled water pond. Flaring event; upgrading discovered stream going into header that goes to flare stacks. Don's know where its coming from; think its a leak on data collection line because no valves are open. Increase since Sep 21 and they can't identify. Have taken sample - 3 tons per day of SO2 emissions - now in excess of 90 tonnes. Will retest and investigate cause. Small flare. Flaring SWAG but flare is out. Cause: unknown why it went out - have had trouble recently. will have measurements on 7 day letter. The caller reported that the potable water had low chlorine levels. The problem was rectified 12 hours later. A pool for treated water had abnormal chlorine levels. Pond effluent water (PEW) line over pressured and relief valve released onsite in upgrader. Happened yesterday @ 1200 hrs. Has been leaking since and crews have been unsuccessful at fixing so far. Contractor vac-truck working to clean. The amount may have reached reportable. Pump turned off yesterday and sewage reached the sump top this morning (11:30). Resulted in ~200 L spill. All onsite. All cleaned up. H2S alarm on 8-2 - reason: they were steaming some sour equipment nearby. Potential exceedance of daily/monthly samples of SO2. No idea of cause but probably relates to plant expansion. They are currently preparing amendment to approval to accommodate expansion. H2S alarm. Investigating cause ; possibly due to testing of new units that are coming online or possibly sour water leak. Cleared now. H2S alarm in area 8-2 due to steaming sour equipment nearby. No adverse impacts. Leak of sour gas - discovered when 2 contract workers became ill and were sent to the hospital in Fort McMurray. Working in plant 8-2. Still investigating the cause and source. Spill of 50% caustic at Aurora site. Cause of spill was valve partially closed.

Flare knockout drum, diversion seal over flows to flare settling pond and water would have no H2S but there is now. Something sending material down. investigating. Air Flaring notification. Have been flaring from 53PC1045B. SWAG is being flared (sour water acid gas), ~ 3.3 tonnes/hr of SO2. Have been flaring since 10:37 and is ongoing, should be finished in next few hours. Cause is problem with 53C101 vessel (leveling off pressure). Air Flaring event for 52PC4015 was open to flare. Air The caller reported that there is intermittent flaring in their stack. They are troubleshooting the system and gas from the boilers is being rerouted to the stack for flaring. No Impact Missed reporting security cost estimate by 2 days. Approval contravention. Cause was late preparation of report. Report due Nov 1. was submitted Nov 3. Air sulfur unit 120D is down. Land Air Air Air No Impact
Spill - hose broke when emptying trailers. clean up - vac truck enroute with lime to do a through job. H2S release - flushing equipment set H2S alarm off. Everything under control now. Flaring LPN/HP flare 82K2 trip due to knockout drum high level. NRU unit venting naphtha vapour and steam. High TVP (total vapour pressure) on sour water tank #53D100. Sample taken this morning. Reason - ever since start-up in Sept, they have had problems keeping oil out of the sour water system. Air Lab samples came back and the Source of the H2S emissions was pinpointed. Plant 16-0 and 16-1 are off-spec and have high H2S in their streams. This is a reportable event as a sour water release.; H2S alarms are going off at the effluent pond. They suspect this is due to the sour water treaters experiencing an upset. They are sampling to confirm. No Impact She had sent a letter last week to approval office and Ft Mc Investigator re: pilot light installation which will result in a noncompliance - pilot system will be off from 2-12 hours (approval requires it continually burns) .

H2S Alarms for effluent pond going off - sour water treater going through an upset. The caller reported that flaring occurred due to instrumentation problems with a vacuum unit. Low temperature on base plant sulphur incinerator stack - under 455 deg C for 15 min and ongoing. Working on repairing; lost flame scanner; fixing ignitor. Flaring of H2S from sulfur recovery unit #2 upgrader. Substantial flaring, most likely over 20 tons temperature related problems due to cold snap. H2S alarms at 0540 and ongoing. Investigating cause. H2S alarms possibly due to: steaming lines to Sewer. Hourly SO2 exceedance at base plant sulfur incinerator stack. possible cause - furnace startup. Methane gas release from open mining pit. H2S alarm; Thawing frozen sample point which splashed out and caused alarm. Flare flame out on hydrocarbon flare, 19-F-3. No identifiable cause yet; investigating. Spill of tailings water to ground. Lasted no more than one hour. Contained onsite in same general area. No idea of cause - investigating. Flaring for - 1 hour which exceeds 6 min flaring limit in approval. Caused by a plugged fan. Flaring of solvents. a sulfur recovery unit went down. Flaring was necessary to stop hydrogen sulfide from being released. The hourly mass limit was exceeded. The caller reported that flaring occurred when a gas compressor was shut down. The flaring mass limit may have been exceeded. The caller reported that a power trip caused the venting of a tank. A vapour recovery compressor was shut down. Hydrocarbon vapour was vented for six hours. Sour water release - regular process stream with high H2S content going to effluent pond contained onsite. Cause of high H2S is process upset. Feed has been reduced to lower H2S level. Alarms at effluent pond are not in alarm. Flare flameout - flare pilot system out. Approval requirement to have continuous flare. SWAG flare is out in #2

Had some odour complaints from sulfur loading area, south of town. Sent out mobile monitoring van and found elevated levels of H2S. Land Spill of sulfuric acid in WTP building due to crack in pipe weld. Mostly contained - some under bldg wall. pipe isolated - covering with soda ash - will wash to sewer with fire hose. Air Flaring incident; ongoing. Compressor tripped. Flaring source is 52 PC 1682 (valve pc pressure control) . No Impact Two flare flow meters are malfunctioning. they are giving erratic readings. The approval requires 100% operational time. Air Venting from tank 4 (diluted bitumen tank). possible instrument failure. Investigating. Air Released some uncombusted hydrocarbons due to intermittent flame out. Air Developed hole in vent gas lines to the flu gas desulfurizer - now have fugitive emissions (flu gas gone through precipitators) but not going through flu gas desulfurizer (condition 4.1.4 of approval) . Air Had trip on SRU # 4 (sulfur Recovery Unit) so will be flaring. Air Tank may be venting. Reason: plant is down; running more to untreated gas oil tank. Has not visually confirmed venting yet. Venting was indicated electronically, which is why they are investigating. Air Tripped sulfur plant and are flaring. Land Treated gas oil spill (~400 L) at Pump station 4. Pump developed a seal leak (pump 21-GM-BA). Spill in contained area. Pump is down. Spilled to ground, no waterways affected. Vac truck en route for cleanup. Spill to be transferred to effluent pond. Air H2S recovery 10 kg - cause unknown. Strip sour water to effluent pond (normally zero) has exceeded approval limit (472 ppm). Reason: H2S stripper unit upset.

Flaring was caused by an instability in plant operations. Repairs are in progress. High H2S in strip water to effluent pond. Cause unknown - suspect fluctuating feed H2S conc. will add steam to stripping samples. will call back to update. H2S alarms are not ringing in. Pond is contained to site. no waterways affected. Plant #64 tailings diverted from naphtha recovery unit - volume unknown - Reason: unit upset in extraction. Missed sewage treatment plant sample last week (effluent sample). Contravention of plant power outage to upgrade transformer, will be another one later.
Surface Potential contravention - may exceed monthly average BOD limit of 25 mg/L. One of the causes was missed Water sewage sample for Feb 22 which was reported in ref# 168570 No Impact Power outage Feb 25, 10:00-10:45. This causes disinfection equipment to go down but everything else shuts down also - so no untreated water went through the system Air Venting from tank D100 (hydrocarbon/ gasoil) due to excess rundown. Air Flaring - commenced because of wet gas compressor trip. Air Flaring event - wet gas compressor trip. Release is of SO2 at 10 tonnes per hour. Still ongoing so final measurement unknown.

Cause was unit instability. A vapour recovery compressor was tripped. So far the compressor could not be restarted. Hydrocarbon vapours were vented to the atmosphere.; 21-K-2 tripped last night (as reported in ref# 169755). They restarted it at 0530 today (Mar 30) and it tripped again at 0710 hrs. They may have to take unit apart for maintenance. Spill - concentration of HCL 1.3% - water wash. Leaked from tank pinhole on connection. Drawing contents of tank down with vac trucks. will soak up and neutralize and dispose of. Failure of control structure on small silt pond and discharged silty water into Tar River. Have contacted DFO to report and caller responding to their direction - caller checking every hour. Caller will provide update tomorrow. Volume unknown.
oil spill - used motor oil. Just found - looks like equipment blew line. Loader coming to scoop up and take to pit to recycle. No drains or water affected. Tank venting of hydrocarbon (natural gas). Vapour from heavy gas tank, due export rate to tank is too high. Due to ongoing venting, they will exceed 20 ton flaring, threshold tonight at -midnight. Venting/flaring is due to compressor down. Flaring from 5PIC793B. Ambient air monitoring violation. Could be data collection problem. main stack has a colorful plume, not a contravention, color due to weather. Spill - raw liquid sewage. Port a potty tank - line broke to holding tank. Has been repaired. Tailings and solvent mixed with sand. emergency dump pond. Sump overflowed to ditch and emergency dump - 30 m3 spilled to ditch and pond. Cause was valve left open accidentally when bringing equipment online. Contained onsite. Will likely pull out and put back into system. SO2 violation - ambient air measurements taken at air monitoring station #11.

ended. No Impact Sedimentation pond releases water to Tar River. 11 samples shipped and 4 were broken. Samples taken 3X weekly (oil increase samples. Samples will be in 7 day report. Surface Polishing pond had high turbidity readings at 1230 hrs today and also 2 subsequent samples. These are field Water samples and have not been confirmed by the lab. The lab's TSS limit is SO mg/L. Cause is snow dam gave away at No Net Lost Lake. Snow dam is being rebuilt. The polishing (settling pond is continuously released to the Athabasca River. After high turbidity found, they stopped flow to the river until resolved. No Impact Small spill of domestic waste water -6-7m3. All cleaned up. Caller thinks controls were shut off by accident, will know more in 7-day letter. Call Reason No Impact Land Leak on weld on sour ammonia water discovered at 1245 hrs. Noticed drip and had to pull off insulation to uncover leak. Evacuated (precautionary) any permit workers in the area. Will try to clamp it off. It that doesn't work, the unit (16-4) will have to be shut down. Fire Hall on standby but not ERP activation at this point. Drip is from crack on weld - small amount by ammonia noticeable. Called in extra help to find a permanent fix for crack. Air Tanks venting - hydrocarbon & nitrogen vapours. No H2S. Instrumentation failure. Started 0400 - 0417 Air Tank 20-D100 is venting natural gas and hydrocarbon vapours. Reason: under investigation. 00172043 196380 27-JAN-2008 13:40 Industry Notification Air Comments: Tank venting on tank 100. Compressor had tripped. Air Caller received notice of odour complaint from AENV investigator. Air Heating on U2 flare stack is lower than it should be. Value reported@ 11.5 megajoules/m2. Limit-> 12 megajoules/m2. Brought flare online in Nov -> thinks the heat has been low since then. Moisture in stream going to flare might be to blame. No Impact Spill of tailings -no naphtha (just water and sand. Volume unknown. Hot water of tailings caused frozen part of dyke to let go so material went into containment area. No waterways affected. Will pump back into pond where it was originally designated to go. Air Stage two of VRU went down at 2300 hours and still not back up. 00172152 197307 29-JAN-2008 05:07 Industry Alleged Contravention Air Comments: Stage 2 of VRU is down; down on January 28 (time not known. Having problems with temperature and equipment tripping. Air Notification -emissions went "off spec". Added anti-foam to amine unit which caused a reaction and now emissions for that went off spec (does not know what that means. Will call back with more information. Air Flaring over 20 tonnes of SO2. Started Jan 24 at 12:04 and is still ongoing. Unsure of cause - has to do with K 100's being down. Air Flaring -> acid gas. Unit instability. Not contravention as of yet -> just a notification. Air
High NOx emissions from G21. Lost generator breaker cooling fan.
Air Air
Diverting valve open to atmosphere, off 8-3. Negligible impacts to env. Ongoing - in recovery mode now. Release of NOX - went as high as 210 kg/hr for fifteen minutes then came back to normal. Reason: started up pump (G20) and exceeded limit for fifteen minutes. Air Tank venting hydrocarbon vapour from 2340 hours to 2350 hours. Reason: compressor K-31-32 not working at full capacity. No Impact Waste water pond (pond C-> sampling machine is broken. Closed outfall -> water level dangerously high chances of overflow. Going to manually sample pond every 2-4 hrs. Might be repaired today but not sure. Air Tank venting -> nitrogen and some sour vapours. Pressure control issue. Stopped @ 1020hrs. Air Possible exceedances for SO2/day due to flaring yesterday. Nothing confirmed yet. Air Land
Surface Water Air
H2S exceedance. Cause unknown. Na hypochlorite spill of 10-20 gallons. Cause -were transferring material. A part on the truck failed and started leaking. No injuries. Cleaned up. No waterways or drains affected. Leak was stopped. No ERP activation. Spilled to a cement pad -snowed over. Potential release of naphtha to effluent pond. Plant is down and trying to get it back up so there could be a potential release. Exceedance is for NOX. Reason: glycol pump failure. Exceedance occurred from GTS and ID Station U6829.

Main stack SO2 exceedance. Greater than 16.4 tonnes/hr. Bringing up sulphur unit & brought up residual. Actual value not avail. Exceedances - had TSS failures on Pond 2 for April 16, 17 and 18, and TSS failure on Pond 6 for April 16. Measurements will be in letter. Reason: frost in ground; gone to liquid mud; affecting TSS numbers. They have done full sweep of all ditches attempting to locate the problem and will rectify when problem located. Refrigerant release R-22, greater than 10 kg. Cause unknown. Flaring events -valve was open to the flare stack. Occurred from 1016 to 1037 hours; from 1044 to 1049 hours and from 1105 to 1149 hours. High level of acid gas in knockout room -they had to open valve to flare. Call Reason Air 22 release from A/C unit; repair in progress at Building 1260, RV2, System A. Reporting potential odour problem. The catalyst beds on the VRU (used for H2S removal are spent, so breakthrough of H2S is happening. H2S emissions to atmosphere measure 40-80 ppm at Source. Not affecting workers (no evacuations. Will take beds out of service and replace them, which will take 6-7 days. Possible offsite odours in the meantime. Will monitor concentration with portable monitors at and around site. Call Reason Air Clean water diversion -> TSS limit is 50 mg/L -> had exceedance. Not sure why. Exceedance in sediment discharge pond #2. Grab sample sent to lab and exceeded limit. Likely due to problems encountered because frost is coming out of the ground and area is being flushed. Creating a temporary sediment pond to correct it. Sample at Shelley Creek showed no impacts (3 mg/L TSS). Their temporary water system for the camp ran out due to weather. They have to turn on their water plant (potable) 2 days early. Will be adding to types of disinfectant, so they will neutralize themselves. Don't have time to flush lines. Issuing a boil water advisory now. Camp capacity is 2500 people. CIC advised that they notify local public health authority. R22 release from Mildred Lake Facility, Bldg 151, unit 41-IRV22. Not sure of reason / cause. Repaired.

Venting from VRU stage i2. Not sure what caused it. Hydrocarbon vapours would have been vented (likely not sour. No other details at this time. Call Reason Air Settling pond # 2 and No Net Loss lake, release sediment with TSS exceeding limit due to extreme temperature. [this seems to be a misclassification of call reason; should be surface water] Exceeded 3 hr TPL (true pressure limit& coming back to normal. Cut back production. Exceedance on Cl2 leaving the plant. Due to failure on automatic chlorinator. Operator currently doing bench test every 30 minutes. Submitted work order to have chlorinator repaired and calibrated in the morning. Tank venting. Hydrocarbon vapours. No H2S. Intermittent b/t 2355 & 0110. Sample on strip water to effluent pond was high in H2S. Reason: probably cold weather related; may be instrumentation; will resample. Two spills of raw sewage; found during an inspection on Dec 16. Spills are in a confined area in a worker's camp. All frozen up; no liquid; thawed out and sucked up by vacuum truck. Treated with water/lime solution, vacuumed again and treated with dry lime powder. Not reported right away because they had no information due to being unable to safety investigate in the confined space. Reason for spill is probably due to pipes contracting and expanding from cold and working apart. Tank venting hydrocarbon vapour. Reason: radar gauge (level indicator) was out of service during the night shift. Tank reached low level and aspirators opened and caused venting. tailings slurry spill (sand, H2O, bitumen) 1000 m3. In a clean H2O ditch. Not migrating. Berm was breached in tailings area. Will remove once frozen. Tailings pond shut down & berm repaired. Stage 1 VRU venting. intermittent on weekend. Second stage was freezing, causing back pressure on first stage. Venting from Tank 20D3. Dilute bitumen, possible H2S. Ongoing over weekend (intermittent. Problem with upstream rates. Call Reason Air Flaring incident -exact start time unknown. Occurred Dec 20th -believe it exceeded 20 tonnes S02. Cause -wet gas compressor trip. 52-K-402 tripped -flaring went through main stack. Additional info -in written report. Call Reason Air Venting from Plant 4 extraction unit -venting light hydrocarbons to atmosphere. Could be ongoing intermittently throughout the day. Reason: managing tank levels (pressures not balanced. When that occurs, it caused Plant 4 to vent to atmosphere. Call Reason Air Unable to complete required testing for FTG stack due to they'll be below required rates while performing RATA. Testing will not be completed for Dec 31, 2008 due date. Lost power to site on Sunday, boilers went down and relieves to blowdown. Release of boiler water -contained in bermed area, surrounding blowdown tank. All on site. No waterways affected. Unknown volume released (1-5 m3. Contravention of approval. Have cleaned surface, but a large portion of it froze, will use a steamer to clean once ambient temp comes up. Call Reason Land Hourly average exceedance on TOU (thermal Oxidizing Unit(converts H2S to S02.
No Impact One of boilers out of the JBR (Jet Bubble Reactor. So boiler is burning Natural Gas now instead of Coke, so that S02 emissions remain the same. Notified @ 1000 hrs today. Not sure when they started. Call Reason No Impact Air Venting from Plant 4. IPS unit was being brought on line, caused a pressure disruption. Call Reason Air Air Tank venting. Gas passed down one of outlets going into tank from one of units. Issue resolved. Hydrocarbon vapours (sour) vented. Air Plant 4 venting. Vapours from extraction process (hydrocarbons, H2S. Due to increased vapour pressure while flushing filters. Will continue to flush filters -there may be venting ongoing periodically. Vented from 2:302:35. Call Reason Air Potable Contamination of potable water clear well with raw water. Reason: under investigation; believe raw water valve Water failed in open position. Volume unknown. Caller will advise health Region who will likely issue a "boil water" order. As of 1410 hours, "Do not drink" signs were posted. Surface Missed industrial waste water and surface run off sample. Not sure why it was missed -under investigation. Water Supposed to have been taken Nov 9. Taken on Nov 11 instead. Air Venting from VRU stage 1. Not a lot. 1 minutes Dec 29 from 0838 to 0839 and 12 minutes Dec 30 from 0438 to 0430. Cause is low temp in VRU Stage 2 that causes freezing and back pressure in stage 1. Time Wind

Spill of diethylamine because of valve failure on pipeline. Is contained within lease -went into closed loop which ends up in storm water pond which goes to tailings pond. If they don't get permission from ERCB to go into the tailings pond, they will use a vacuum truck to suck it out. No other water bodies involved. Time Wind Dir/Speed 15:00 Call Reason Land High oil and grease readings in outfall ponds that leads to Athabasca River; sample not at the usual place.
Venting due to vacuum issues. Light end hydrocarbons. Call Type Release Call Reason Air. Opacity exceedance on the main stack. Reason - preparing for CO boiler #2 outage. Corrective action taken and just had one hourly violation so far. No Impact Spill - sewage leak on 2 tanks. Noticed during inspection. Inlets have small leaks, ice is forming. Approx. 2 L in each case. Contained - frozen. No vegetation affected. Supervisors notified, investigating. No Impact Notification. Release of PCB containing oil -it just went to tailings pond. Occurred approx 1 hour ago. Caused by a contractor error. It was supposed to go offsite and contractor took it into pond. The oil will not be removed from the pond; the amount of PCB would be negligible compared to the size of the pond. No Impact CO boiler #2 has a tube leak. So unit down for repair & bypassing Air Opacity exceedance on main stack No Impact Stage 2 VRU was down for 15 mins. Air Low pressure stacks are flaring. Air Opacity on the main stack for one hour.

Based on Syncrude's internal investigation, they considered themselves as not a likely source for these TRS exceedances. Suncor indicates that the increased TRS levels originated from the Suncor site from the area of Tailings Pond 7. break up. It likely occurred as a result of ice. They had a overflow of bitumen slurry at plant 82. Estimated volume of >4 m3. None went offsite -it went into a containment area. Trying to fire up system and a plug may have caused the bitumen to overflow from the breaker. CEDA has been called to vacuum up the spill. No other issues such as injuries. Call Reason Land Hourly TRS exceedance at station 12. Settling pond discharges into Athabasca River, it is coming back into the settling pond due to break up of water. Water break up started Saturday. Possibility of high TSS. Will monitor. No plant site at this location. Continuing hourly TRS exceedances at station U2. Five minutes venting from stage 2 VRU. Not sure if sour gas or not. Reason or cause unknown. COD violation -surface water ponds collecting runoff. Daily value taken 205 mg/L, limit 200 mg/L. TSS excursion on NSE project. Cause -unknown. Surface runoff -ultimately flows to Steepbank River. Hourly Average -TRS exceedance. Station il2 Tank 20D14 is venting natural gas - now sporadic but they are working to get it to stop completely. Reason: under investigation. Not a high volume of gas venting. Tank is a naphtha tank. TSS exceedance due to new construction (C2 pond) and spring runoff from plugged culvert (Pond 2). Water from Pond 2 is released to a waterway (Muskeg River) ~2 km away. Exceedance at settlement pond #6 of residue ammonia level due to ammonia discharge from sewer pond since last winter; will monitor on daily basis; has been following guideline for aquatic lives.

Opacity exceedances -loss of fuel causing high pressure, created problems with ID send. All over 40% no exact values given. Had to swing the boilers out of the JBR (Jet bubbling reactors. Leak on boiler 1-internal -steam. So routing emissions through stack 31 instead of stack 37. Still happening. Working to fix problem. Potential for elevated S02 &/or particulate. AA/ On August 29, 2009, Boiler 1 experienced a tube leak at 04:48 hours at which time it was routed to out of the JBR. Opacity exceedance occurred from 05:12 to 05:24 hrs, 06:36 to 06:48 and 07:48 to 07:54 hrs as boiler was take out of JBR. The point of release was the Old Power House Stack 31F-7. The average opacity reading was 68.10 70.45 61.69 49.81 50.74 The released staff from stack 31 consisted of light fly ash from combustion of coke. A tube leak on Boiler 1 resulted in very hot flue gas entering JBR which triggered an Emergency Shut Down which caused the boiler to transfer out of JBR and in+BL7642to Plant 31 Stack. The FD and ID continued to run to cool the boiler. The fans carried all the remaining furnace and debris into stack 31 which resulted in the opacity excursions. Spill of tailings from Millennium from north booster pumphouse. This is just water and sand. 410 m3 went to pipe corridor & contained & 40 m3 to adjacent ditch.

Notification of a small failure in a pipe and subsequent leak from the amine unit. A pinhole leak was noticed a few days ago (not exactly sure which day -yesterday or the day before. As a result a small amount of liquid amine and H2S were released. They assessed it and decided to put a sleeve on it as a temporary fix until they could shut down. However, the sleeve did not work. They will instead commence a staged (slow shutdown to fix the pipe. An hour ago, two workers who were working on the pipe had liquid splash on their hands. They were taken to the clinic for observation because there was H2S involved. There were no injuries. The pipe should be fixed by Monday. He will update if this does not occur.

JC; On August 6, 2010 the Fort McMurray on call officer received 3 odour complaints from Fort McKay in a span of 30 minutes. The Industrial Odour Protocol was enacted. Syncrude, Suncor, CNRL, and Shell all called into the air info line with updates. Syncrude, Suncor, and Shell indicated there plants were on spec and CNRL was shut down. Based on wind direction and information received in this office, the probable source is Suncor. AENV and Suncor are meeting to discuss their message on the air information line on Thursday August 12, 2010. AENV continues to monitor odour events and will work with industry and public at such times. No further action taken by AENV at this time.

The chlorine pump vapour locked so therefore not feeding properly. Fixed problem. minimum is supposed to be 0.1 mg/L Cl but was at 0.04 mg/L. This lasted for 2 hours. 11 NOX exceedance at cogeneration plant. Lost fuel/steam injection. Call Type Call Reason Alleged Contravention Air Exceedances of NOX at the hydrogen plant, secondary upgrading stack: 46-F-50. 0800-1000 Aug 4, was at 58.8 kg/h and limit is 57kg/h. Don't know what occurred, will include in 7 day letter. Stripped water going from Plant 16-4 to effluent pond exceedance of 472 ppm H2S in the water. Cl residual level for potable water at plant was recorded at 4.3 mg/L. They were using a temporary pail trailer and a 45 gallon drum with hypo for disinfection. Reduced frequency of pump and the residual was reduced. At 4:00am it was down to 3.8 mg/L. Limit is 4. Caller reporting flaring event. Unit 81K2 tripped resulting in sour gas flaring for 17min. As a result of the high volume of gas, they blew the seal from the low pressure flare to the high pressure flare. They could not atomize the high pressure flare and it lead to incomplete combustion and black smoke in the flare. Caller is not sure when the incident took place but will find that information and update AENV. NOX exceedance. COGEN had a boiler trip. Pump stopped working last night due to a power surge. Loss of pressure in distribution system. Went for 20 minutes. Potable water for Elk Point Camp (unsure of how many people. Nobody affected by this. Lab samples sent for analysis. Everything came back fine. Will include in 7 day letter. Caller reporting venting from VRU due to compressor problems. Vented from 20:22-21:34hrs and the again at 21:42hrs (ongoing.

acid caustic storage building. The release is contained within a building. Not sure how much has currently spilled, but is is leaking 5 gallons per minute when the pump is operational. The pump runs periodically through the 24 hour period. This started as a small leak that has gotten worse. They have parts on order estimated parts arrival is Aug 22. The caustic is currently running to the oily water sewer and is being diluted with water before it enters the sewer. Tank venting of hydrocarbon vapors and nitrogen from Tank D-1. Unsure how long it'll vent but venting because they are having issues with their vapor recovery system. Turbidity of .1 Ntu's not to be over for 15 mins. during the day. The units that were taking the reading are supposed to shutdown before the 15 min sessions but did not. There are 6 units within the system, two of the units have been taken out of service for repairs. Grab samples for turbidity showed less than .1 NTU's and particle counts were not over 20 and the membrane integrity tests were okay. They will recalibrate the two units in the morning. This is on the potable water system. Driving by source and there's a smell of ammonia. There's a coloured beige/grey plume coming from the smoke stack when it's usually white. R22 release, greater than 10 kg, does not know exact amount. Discovered this morning. In the process of being repaired. Caller reporting dissolved oxygen exceedance. Weekly DO Average was below 6.5 on 3 occasions in July. Sample taken from sedimentation pond. Pond is discharged into surface water (fish bearing). Cause - not a lot of water running into pond (not dewatering); pond has got really stagnant. On July 23, the source set up an aerator to increase oxygen levels. On Aug 2, the pond has stopped discharging - ran out of water. Caller reporting a release of R22, >10kg. Unit is being repaired as we speak.

Spill of condensate contaminated with sour water, 3 m3. Cause: sour water system backing up to condensate system and the condensate overflowed. The spill went to a containment ditch onsite. No waterways nearby. Spill did not go offsite. Spill was cleaned up. Happened on August 23, 2011 at 18:00. Not called in at that time as the cause of the spill was being determined at that time. Time Wind Dir/Speed Call Reason Land Caller reporting accidental release of Catacarb -corrosion inhibitor. Caller is not sure how much was released. Release happened last night and again today. Source is having some problems with Plant 6 (no details available. Caller is not sure where the product was released from -maybe the tower. Could have been over pressured and a little mist was released. Product localized to immediate operating area. Product would have been released to cement and top of building. Call Reason Land Caller reporting a notification -source exceeded the allowable S02 emissions. Source was flaring due to temperature and pressures issues in the plant. Plant started up last week -could be a contributing factor. CSConversation with environmental staff stated that AENV in Edmonton (Approvals have asked CNRL to report every time they exceed the 20 tonne/day limit, as per their approval they are not required to report when they exceed 20 tonnes/day. From lAug to 25 Aug 2011 they have been flaring VRU for greater than 10 tonnes S02. This 10 tonnes is for the 25 days. Stopped flaring at present. Tank venting from D-1. The constituents would be hydrocarbon vapours and nitrogen. They have high back pressures in the vapour recovery system. Started at 0850 and is ongoing and intermittent. They are trying to optimize and balance that VRU. Leak of 98% Sulphuric Acid. Releasing about 1 gal per min, first observed at 0730hrs today and caller just notified at 0910hrs. Leaking from the water treatment plant (caller assuming its potable water), a blocked valve on the regen system. Spilling into the oily water sewer, where it's being diluted by water. Sewer goes back into process system. No way for spill to reach environment. To contain spill they will bring up back up system, and shut down current system. There has been a power outage and the PSV lifted on the exchangers. Released produced water. happened at Jackfish 1. There was 10 cubes released and all Vacced up Call Reason Land A potable water contravention allowed 4.0 mg/L Cl readings conducted at 1315 hrs showed 4.2 mg/L. End users are testing every 15 mins at this time. Flaring is part of their regular route of the system but it has now gone over their limit of 20 tons of S02. Not an exceedances, but they always report to Alb Env when over 20 tons, and write a 7 day letter. Call Reason Air

Evacuation at the coke disposal area. There was a small fire in the waste coke pile, that caused H2S to be released. The structure units rated area at 23ppm. The upper threshold is 15ppm, so this caused hazmat to come out. Hazmat put water on fire area. Hazmat's readings could not match the 23ppm and their readings were much lower. Hazmat evacuated 15 people as a precaution. Hazmat gave the all clear at 2100 hrs. No injuries to report. Cause of fire unknown, fire was small. More info to come in the 7 day letter. Suspected high TSS in surface H20 released to River. Pumping accumulated surface H20 to River. Sample collected @ 0830 hrs and the results indicated TSS @ 157 mg/L.

They noticed through the trending that they went below the license limit for stack top temperature, but they are unsure of the exact hourly average. The limit is 624 deg C. She will confirm if there was a contravention and put the details in the 7-day report -they may have brought it back up quickly enough to avoid an hourly contravention. No Impact Spill of recycled water (water used within the base plant process). ~ 2000 gal. Due to breach of dyke on the East side. The water runs off into a seepage area which leads to a sump back into the recycle area. No potential for offsite impacts. Air Odor complaint there is a sulfur smell that's stronger than normal. Caller just drove by the plant and the flares are huge. Call Reason Air Air Flaring produced sweet gas due to power outage last night. Still on going, but the power is back so it will stop soon.

Flaring lasted until after 6pm. >20 tons/S02 were released. Land 100 m3 of processed water went to ditch and froze. Caused by a pipe that over flowed. They have opened up another line to handle the flow because the other pipe froze, causing the spill. Caller believed they will clean up when thaws. Caller wasn't provided any info about the clean up. Spill remained onsite. Call Reason Land Land Release of 5L of grey water. Workers were asked to provide a heater to a system to assist another contractor with a wash car. And the workers placed the insulated tarp and heater around waste tank. When they returned they found a spill of 5 L of grey water on the ground. Clean up complete. Call Reason Land Air Caller reporting an hourly opacity exceedance. Cause - nutriator dip leg plugged on coker 81. Source is trying to dump coke from vessel - some light materials are being carried over to CO boiler. Air NOx exceedance. Hourly for one hour. Due to excessive boiler firing rates from high steam loads on steam header. Air Lose sulphur recovery unit, has plant upset, might have a possible exceedance of S02 at the oxidizers between 1300 to 1400 hours, cannot confirm the amount of exceedance yet till Monday.

Flaring from 25 PIC 862.Thinks it was 100 km/hr. Notification - there is fouling on the back end of the hydrotreater unit. They are planning a chemical injection cleaning for Wednesday. If unit goes down before that, they may have some faring of butane. Notification of flaring from bldg 5-C-15, at the base plant upgrader. Reason - naphtha system down for preventative maintenance. No violations. Started plants up over the weekend. Starting 15 minutes ago, air blower issues, and have some black smoke coming off the flare Reporting high potential for odours over the next 3 weeks during shutdown. Potential for odour increases when NRU is down and naphtha is sent to untreated tailings pond. Caller could not say odours were bad at time of call. C/N also advised air monitoring bus is down for repair - will be ready to go tomorrow. Reporting pumping sour water to tailings pond #1. Associated with base camp shutdown. Odour potential. Due to Williams shutdown, they will be flaring June 11-20. Williams Energy normally takes their rich gas (low sulfur). Bright flare - low SO2.Expect no adverse effects wants to waive 7-day letter. Also notifying of Source main startup June 15-17. Big flare. Air monitoring van will be touring site. Had an exchanger fail that is causing wet gas to be sent to flare. Has potential to knock out flare pilot. Will call back if it does. Reported that an engine malfunction on heavy hauler lost 175 litres of hydraulic oil. Have recovered with sand put contaminated sand back into process. Rec'd letter Oct 3. 16:02. Reporting that a D7 cat is on fire at plant site. Were burning brush at the time. This morning had to send diluent from upgrader #1 to south tank farm. Reason is frozen tank. Potential for odour because there are light ends in the diluent. Courtesy call. Flaring event from swag system 53C10 - SO2 hit is possible - sour water went into circulation and lost system 2150 - ongoing. Notification that VRU will be shutdown for ~8 hours creating odour potential. If issues/incidents arise she will update and provide letter. Flaring - ongoing - for a while yet.
