Specifically, EPA sought to identify whether there were examples of pollution caused by activities within these industries that occurred under an environmental regulatory structure like today's that required taxpayer funded cleanups. EPA believes that this type of cleanup case would be indicative of the potential need for CERCLA 108(b) financial responsibility requirements. EPA prioritized identifying and analyzing Superfund National Priorities List (NPL) sites as those tend to be the largest cleanups with the greatest likelihood of significant taxpayer expenditures. However, to supplement this evaluation, EPA also examined a number of sites that are not listed on the NPL, but that required removal actions. This report is focused specifically on EPA's identification and evaluation of such non-National Priorities List (NPL) Removal Sites within the Petroleum and Coal Products Manufacturing industry. SEMS Query In order to establish a universe of non-NPL sites to investigate, in November 2018 EPA queried the EPA's Superfund Enterprise Management System (SEMS) database.1 Within SEMS, EPA filtered the 83,000 records for sites that were not on the NPL. EPA also excluded sites at which cleanup occurred under the Superfund Alternative Approach (SAA) from this analysis. EPA considers those sites in its analysis of NPL sites.2 This resulted in 7,565 sites. These sites include, sites designated in SEMS as Removal Only Sites (where no site assessment work needed), Referred to Removal - Needs Further Remedial Assessment, and Referred to Removal - No Further Remedial Action Planned. This approach erred on the side of over identifying potential damage cases as some of these candidate sites would be already accounted for as part of other NPL sites. Next, EPA filtered the 7,565 sites using SEMS industry identification category (Primary and/or Secondary Subcategory Name in SEMS), which EPA used as a proxy for the type of industrial activity that took place at the site. EPA specifically looked at those identified as oil and gas refining, coke production, chemicals and allied products, chemicals/chemical waste, and electric power generation and distribution. This filtering yielded 363 removal sites. Petroleum and Coal Products Manufacturing Sites The 363 removal sites included sites at which any of the three additional classes - Chemical Manufacturing, Petroleum and Coal Products Manufacturing and the Electric Power Generation, Transmission and Distribution - were identified as the industry Primary and/or Secondary Subcategory Name3. At this point in the analysis, EPA turned its focus to Petroleum and Coal Products Manufacturing. To evaluate whether the removal actions resulted from pollution that occurred under a modern 1 SEMS data for removal cases capture CERCLA responses but are not comprehensive of all potential releases. Alternative data sources reveal releases unrelated to CERCLA, and therefore not tracked in SEMS (e.g., non-CERCLA enforcement cases related to the Clean Air Act and Clean Water Act) 2 EPA-HQ- SFUND-2019-0087 3 SEMS industrial designations within SEMS were used to identify sites (damage case) for evaluation. Incomplete or misplaced designations may result in some cases going unidentified. No additional reviews of non-selected sites were performed unless EPA experience and program knowledge revealed omissions from the list. 1 ------- regulatory regime for these sites, EPA then further eliminated the Electric Power Generation, Transmission and Distribution, chemicals and allied products, and chemicals/chemical waste sites. This left the sites for which SEMS listed petroleum and coal products manufacturing as the Primary and/or Secondary Subcategory Name. From the original 363 removal sites as identified, EPA found that 51 of these 363 removal sites potentially fall within the North American Industry Classification System (NAICS) codes 324110 for Petroleum Refineries, and 324199 for All Other Petroleum and Coal Products Manufacturing. EPA narrowed its scope to focus on evaluating these 51 sites Screening Out Potentially Responsible Party (PRP) Funded Actions The focus of EPA's investigation was to identify sites at which pollution occurred in a modern environmental regulatory structure that required taxpayer funded cleanup. As a result, EPA conducted a preliminary review of the available site documents for each of the 51 Petroleum and Coal Products Manufacturing removal sites through the EPA's SEMS and On Scene Coordinator Response (OSC Response) databases. The information collected as part of this review is available in the docket to this action.4 The documents available through the SEMS and OSC Response databases largely comprise Pollution Reports and Removal Action Memoranda. From this initial review, EPA identified23 sites that appeared to possibly require government funded action or a mix of government and PRP funded action warranting further review. Twenty-eight sites PRP lead sites were screened out of the analysis. Screening Out Additional Non-Petroleum and Coal Products Manufacturing Sites Once EPA identified these 23 Removal sites at which removal actions were funded in part or in full by the government, EPA conducted initial reviews of site-specific data from the documents available through the SEMS and OSC Response databases. The data generally included information on the nature of the operations at the site. With this information, EPA determined that 12 of the 23 removal sites with government funded removal actions did not have Petroleum and Coal Products Manufacturing Industry operations and were therefore outside of the scope of the rulemaking. Once these additional sites were screened out, 11 Petroleum and Coal Products Manufacturing Industry sites that possibly required government funded removal actions remained. Screening Out Sites with Insufficient Response Documentation EPA conducted thorough reviews of the available site-specific information and documents for each of those 11 petroleum and coal products manufacturing sites with government funded actions. However, when EPA consulted the SEMS and OSC Response databases about these sites, there was insufficient information about removal actions at four of the sites to conduct a thorough analysis of the site. At three of the 12 sites, there was no removal action documentation at all: E-Biofuels (INN00510768); Petroleum Products Corporation #2 Fuel Spill (PAN00305647); and New Castle Catalyst Release (WYN000801987).5 At the Suncor Refinery Yellow Plume site (CON000802548) EPA was able to locate an OSC pollution report for the site. The pollution report indicated that no response or removal actions occurred at the site and thus there were no removal documents to analyze. 4 EPA-HQ- SFUND-2019-0087 5 The OSC Response website does have a webpage for the E-Biofuels site. The E-Biofuels webpage lists the site as "pending." See EPA OSC, "E-Biofuels LLC," accessed May 15, 2019 at: https://response.epa.gov/site/site profile,aspx?site id=7936. 2 ------- As a result, EPA focused on the remaining seven Petroleum and Coal Products Manufacturing Industry removal sites for which the agency located sufficient documentation to conduct analyses of those removal actions. Analytical Steps and Methodology Once EPA identified these seven Petroleum and Coal Products Manufacturing Industry removal sites at which removal actions were funded in part or in full by the government and EPA confirmed that sources documenting the removal actions at those sites were available, EPA collected site-specific data from the documents available through the SEMS and OSC Response databases. The data collection included site operation and contamination dates to determine if the site may have operated and/or experienced contamination under a modern environmental regulatory regime. EPA also collected data on the nature of the operations at the site, the cleanup activity that occurred at the site, the contamination at the site, descriptions of the incident that caused the contamination, the sources of contamination, and the media at the site that was contaminated and was removed in the removal action. The data collected as described was entered into a spreadsheet for comparative purposes and can be reviewed within the docket.6 Of the seven Petroleum and Coal Products Manufacturing Industry removal sites that featured government funded cleanup activities for which EPA collected data, seven were classified as fully funded by the government. Table 1 - Funding Sources for Cleanup Activities at Government Funded Petroleum and Coal Products Manufacturing Industry Removal Sites Funding Source Count Government 7 Mixed 0 Total: 7 Of the eight Petroleum and Coal Products Manufacturing Industry removal sites that featured solely government funded activities for which EPA collected data, seven were associated with industry specific activities for NAICS 324110 - petroleum refining, one was associated with industry activities for NAICS 324199 - other petroleum and coal products manufacturing. These are shown in Table 2 below with the associated North American Industry Classification System (NAICS) codes. Table 2 - Six Digit NAICS Classifications for Government Funded Petroleum and Coal Products Manufacturing Industry Removal Sites Six Digit NAICS Industry Classification Count 324110 Petroleum refineries 6 324199 Other petroleum and coal products manufacturing 1 Total: 7 6 EPA-HQ- SFUND-2019-0087 3 ------- EPA also determined whether the contamination at the non-NPL sites were the result of a single, immediate releases or catastrophic incidents, versus a long-term, gradual release. Of the eight Petroleum and Coal Products Manufacturing Industry removal sites that featured only government funded cleanup activities for which EPA collected data, there were three sites that had single/catastrophic incidents and six sites with long-term releases. Note that the total count in Table 3 is more than eight because a single site may have experienced both long-term releases and a catastrophic incident. Table 3 - Contamination Timing at Government Funded Petroleum and Coal Products Manufacturing Industry non-NPL Sites Contamination Timing Count Single Incident 3 Long-term Releases 6 Total: 97 EPA also collected the contaminants that necessitated the removal action. At the seven Petroleum and Coal Products Manufacturing Industry non-NPL sites that featured only government funded cleanup activities for which EPA collected data, volatile organic compounds (VOCs) required removal at six sites, lead required removal at two sites, and asbestos, mercury, polychlorinated biphenyl (PCB), sulfides, and sulfur dioxide all required removal at one site. Note that the total count in Table 4 is more than seven because at some sites, there was more than one contaminant that necessitated a removal action. Table 4 - Contaminants that Necessitated Removal at Government Funded Petroleum and Coal Products Manufacturing Industry non-NPL Sites Contaminant Count Petroleum Hvdrocarbons/VOCs 6 Lead 2 Asbestos 1 Mercury 1 PCB 1 Sulfides 1 Sulfur dioxide 1 Total: 14 EPA also collected data on the cause or causes of single/catastrophic types of incidents that led to contamination. At the three Petroleum and Coal Products Manufacturing Industry non-NPL sites at which a single release necessitated a removal action, mechanical failure led to contamination at two sites, and flaring led to contamination at the other site, as shown in Table 5 below. 7 The figure does not add up to 7 sites, because multiple issues can occur at one site. 4 ------- Table 5 - Causes of Contaminating Incidents at Government Funded Petroleum and Coal Products Manufacturing Industry non-NPL Sites Cause of Contaminating Incident Count Mechanical Failure (e.g., leaks from tanks and drums; malfunctioning regenerative thermal oxidizer) 2 Flaring 1 Total: 3 EPA also collected data on the sources of contamination or the contamination vectors that occurred at each site. Of the seven Petroleum and Coal Products Manufacturing Industry non-NPL sites that featured government funded cleanup activities for which EPA collected data, five involved releases from hazardous substances or waste stored in abandoned drums or tanks (primarily abandoned tanks and drums containing polychlorinated biphenyls (PCBs) or volatile organic carbons (VOCs), three involved contaminated soils (e.g., PCB discharges from equipment or storage containers), two involved abandoned asbestos-afflicted material (e.g., debris piles), and one each involved buried drums or tanks containing waste, mismanaged onsite runoff, waste disposal pits or depressions, flaring causing air emissions, and equipment malfunction causing air emissions. Note that the total count is more than because a single site may have had multiple sources of contamination, as shown in Table 6. Table 6 - Contamination Sources/Vectors at Government Funded Petroleum and Coal Products Manufacturing Industry non-NPL Sites Contamination Source Count Storage of hazardous substance or waste in drums or tanks (primarily abandoned tanks and drums containing PCB or VOCs) 5 Contaminated soil - 3 Abandoned asbestos afflicted material (e.g., debris piles) 2 Buried drums or tanks containing waste 1 Mismanaged onsite runoff 1 Waste disposal pits (unlined) or depressions (natural or excavated) 1 Flaring causing air emissions 1 Equipment malfunction causing air emissions 1 Total: 15 Finally, EPA also collected information about the contaminated media at each site that needed to be removed or contained as part of cleanup activities. At the seven Petroleum and Coal Products Manufacturing Industry non-NPL sites that featured government funded cleanup activities for which EPA collected data, cleanup involved: the removal of debris at four sites; soil at four sites; the removal of building and structures (primarily storage tanks) at three sites); the containment and monitoring of air emissions at two sites; the removal of liquid wastes at two sites; the removal of, specifically, surface soil, at two sites; the removal of sludge at one site; and the removal of, specifically, subsurface soil at one site. Note that more than one type of media may have been contaminated at a site, which is why the total number of contaminated media shown in Table 7 is greater than seven. 5 ------- Table 7- Contaminated Media at Government Funded Petroleum and Coal Products Manufacturing Industry non-NPL Sites Contamination Source Count Debris 4 Soil 4 Buildings and structures (primarily storage tanks) 3 Air 2 Liquid waste 2 Surface soil 2 Sludge 1 Subsurface soil 1 Total: 19 Based on Tables 6 and 7, abandoned tanks and drums containing hazardous substances and wastes, particularly PCB and VOCs, as well as corresponding leaks of hazardous materials from those abandoned containers to surrounding soils, were the primary causes of contamination that necessitated response actions at the seven Petroleum and Coal Products Manufacturing Industry removal sites. Screening Out Legacy Issues After compiling information about the risks and history of each site EPA sought to identify instances where issues arose under a regulatory structure like today's that resulted in taxpayer funded response actions. To do so, EPA first screened out the removal sites where the date of the pollution incident or activity was pre-1980. EPA chose 1980 as a cutoff point to screen out legacy issues because it was the year that Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980 was enacted, as well as the initial establishment of regulations under RCRA Subtitle C governing hazardous waste treatment, storage, and disposal facilities in May 1980. EPA believes this is a conservative screen in that only the initial RCRA regulations were in place in 1980 and would be refined, expanded and enhanced several times over the next decade. Moreover, the Agency's enforcement authorities expanded in the 1980s as the RCRA program matured. Notably, the passage in 1984 of Hazardous and Solid Waste Amendments (HSWA) resulted in many regulatory changes and enhanced enforcement mechanisms. The dates of RCRA and CERCLA were given greatest consideration due to the large number of instances of waste management, land disposal and contaminated soil issues identified in the review of the removal cases. In many cases, the Superfund site documents would not date where specific releases occurred or polluting activities (e.g., land disposal in unlined impoundments) ceased. At sites where there were multiple releases and/or activities with varying dates, EPA used the most recent date to err on the side of being over inclusive. For example, if a removal site had documented issues in 1968 and 1981 the site would not have been screened out because at least one of the dates occurred in 1980 or later. In instances where EPA could not identify pollution activity or release dates with sufficient confidence, EPA used the relevant operation's end date. For example, at a facility where the exact dates of releases were unknown but industrial activity ceased at the site in 1985, EPA would have used 1985 as the date for applying the screen. In such an example, the site would not have been screened out of the analysis. This analytic approach resulted in EPA erring, again, on the side of being over inclusive. 6 ------- Based on the data collection about site operations, dates of operation, and contamination dates at the seven Petroleum and Coal Products Manufacturing Industry sites that required government or mixed funded cleanup activities, EPA determined that the pollution at two of the sites was related to legacy practices. In accordance with the methodology, EPA views such legacy occurrences as not representative of the types of current-day risks that would warrant regulation under CERCLA 108(b). The two legacy sites that EPA identified and determined were not representative of modern risks and therefore did not warrant further investigations were Ida Refinery & Dump (LAN00067364) in Ida, Louisiana, and Hot Springs Refinery (SD0010171860), in Hot Springs, South Dakota. At both sites, contamination resulted from refinery operations prior to the 1970s. At the Ida Refinery & Dump, Grand National Oil Company constructed and operated a petroleum refinery from the 1940s to 1957, at which point Ida Oil and Gas Company took over the facility and continued operations to 1966. There was no industrial activity at the site after 1966. Refining operations at the Hot Springs Refinery started in 1932 and continued into the 1940s. According to the site documents, the operators of the refinery disposed of waste products from the refining process in earthen pits approximately 20 by 30 feet and covered the pits with teakwood planks. Although refining operations ceased in the 1940s, the site continued as a bulk petroleum storage facility into the 1990s. Contamination at the site was impacted by the construction of a state highway over the main waste pit from the legacy refining operations. The removal of the above legacy sites left five sites where the pollution at issue may have occurred under modern regulatory regimes. For these five sites, EPA cross referenced the site operation and contamination dates with the implementation of relevant federal and, if available, state environmental regulations to determine if those relevant regulations were in place at the time of operations and when the pollution occurred. Detailed case narratives were prepared for each of these five cases and are included in Appendix III. The key findings of EPA's detailed evaluations for these five sites are summarized below. Summary of Findings from the Detailed Review of Petroleum and Coal Products Manufacturing Industry Removal Sites with SYienlial Modern Regulation Releases and Risks To assess the five sites that remained after those screens, EPA first conducted a detailed review of case files to compare the environmental issues at the sites to the regulations applicable today. At two of the five removal sites (United Energy in Evanston, Indiana; and Browns Island Emergency Response in Weirton, West Virginia), while the environmental releases had occurred recently, EPA concluded that they had resulted from legacy waste management practices. For instance, at the United Energy site, the refinery operations ceased during the 1970s and the site was abandoned. Though long abandoned, the presence of former tars pits and waste oil lagoons, PCB-stained soil, and PCB oils tanks at the site posed threats to public health and the environment resulting EPA's removal response in 2012s. Similarly, at 8 2012 Action Memorandum - Request for Approval and Funding for Removal Action at the United Energy Site, Spencer County, Evanston, Indiana. 7 ------- the Browns Island site, while operations at the former coke by-product plant ceased in 1982, in March 2008, 300 gallons of liquid organic chemicals (primarily naphthalene) spilled from an abandoned tank, as the current owner of the facility was in the process of facility demolition. EPA's case files on site showed the current owner notified the National Response Center (NRC) to report the spill and subsequently conducted the cleanup activity with EPA's oversight; total fund expenditure reported at this site was $6,700. At two other sites (Benicia Valero Refinery in Benicia, California; and St. Rose Air Assessment Site in St. Rose, Louisiana), EPA concluded that the releases were caused by a one-time incident (e.g., malfunctioning of sulfur removal equipment at the St. Rose site and power outage at the Benicia) which resulted in release of air pollutants (e.g., hydrogen sulfide and other organic vapors at the St. Rose Site and sulfur dioxide at Benicia).910 Although not designated as PRP-lead actions in the SEMS database, according to EPA's review of site documents, the PRPs largely financed and performed the response actions with oversight of EPA and state agencies. SEMS expenditure data show EPA incurred $75,000 in Fund expenditures to conduct an air quality monitoring and assessment at the St. Rose site, after the state requested assistance from EPA. No Fund expenditures were reported at the Benicia site. Finally, the remaining removal site was Lake Charles NRG, located in Lake Charles, Louisiana. Petroleum refinery operations occurred at this site from 1983 to 1999. The refinery operations consisted of processing petroleum feedstocks into naphtha, fuel oil, and residual fuel oil. Rebel Energy, Inc. constructed the site and began intermittent operation in 1983. Following several ownership changes and bankruptcies, the site was transferred to NRG in 1998. NRG operated the facility for a short time during 1999 and subsequently abandoned it. Site assessment beginning in 2000 identified hundreds of storage systems (including above-ground tanks, sludge boxes, vessels, and drums) and process equipment containing over 200,000 gallons of hazardous liquids, solid sludge, and acid liquid.11 A subsequent visit by EPA also revealed a tank that had failed, and oil was leaking from the secondary containment structures. EPA concludes this site represents a case where a release or threatened release of hazardous substances took place under the modern regulatory framework and required taxpayer funded cleanup. As described in more detail in the Role of Federal and State Programs section below, the primary regulations governing Above Ground Storage Tanks (ASTs) used for storing oil and petroleum products are the Spill Prevention, Control, and Countermeasure (SPCC) regulations, 40 CFR 112. These regulations have been in place since 1990. Tank systems used to store hazardous waste have also been regulated under RCRA (40 CFR Parts 264 and 265) since 1986. Moreover, according to EPA's records, no financially viable PRPs were identified for this site, and SEMS expenditure data show that EPA incurred an estimated cost of $2.3 million for response and enforcement activities. Table 8 below presents an overview of EPA's methodology for determining the five sites that warranted further investigation, and EPA's conclusions regarding whether the release events that occurred at those sites are representative of contemporary risks. 9 2017 Pollution Report for Benicia Valero Refinery Site. 10 2014 and 2015 Pollution Reports for St. Rosa Air Assessment. 11 2012 Pollution Report for Lake Charles NRG site. 8 ------- Table 8 - Overview of EPA's Review of Petroleum and Coal Products Manufacturing Industry Removal Sites and Results of Detailed Review of Sites Potentially Representing Contemporary Risks Total superfund removal cases evaluated Number of removal cases screened out based on pre-1980, or PRP lead status Detailed review concluded release occurred prior to modern regulations Detailed review identified a possible modern regulation release, but minimal or no taxpayer expenditures Cases with release(s) under modern regulation that required taxpayer funded response 51 30(16)12 2 2 1 More information about the five sites subject to the detailed review is available in Appendix III of this document. Appendix III provides the operational history of each site, an overview of any regulatory and enforcement actions that occurred, and EPA's evaluation of the applicable regulations for the types of releases that occurred at each site. 12 The number in parenthesis indicates the sites that were also removed at this stage in the analysis: 12 sites for which EPA determined the industrial activities did not involve either petroleum refining or coal products manufacturing, and four sites for which there was not enough documentation to be included in the analysis. 9 ------- Appendix I.

Detailed Case Narratives of Petroleum and Coal Products Manufacturing Industry Removal Sites with Potential Modern Regulation Releases and Risk EPA sought to identify examples of releases in the petroleum and coal products manufacturing industry that occurred under an environmental regulatory structure like today's and that required a taxpayer funded cleanup. EPA used these examples to evaluate the current risk of release at Petroleum and Coal Products Manufacturing Industry facilities. As part of this effort, EPA developed the risk profile using petroleum and coal products manufacturing sites that experienced releases requiring assessments and/or removal actions, but that were not on the NPL. To identify this universe of petroleum and coal products manufacturing facilities, EPA used the Superfund Enterprise Management System (SEMS) database and queried for non-NPL sites. EPA further winnowed the results to Petroleum and Coal Products Manufacturing Industry facilities, which resulted in 51 petroleum and coal products manufacturing facilities that experienced a release that were not on the NPL. From these 51 facilities, EPA further screened out PRP funded assessments and actions, sites for which operational activities were not in Petroleum and Coal Products Manufacturing Industry and were therefore outside the scope of the rule, and sites which did not have enough response documentation to conduct a detailed analysis, which left eight facilities. Finally, EPA collected data from the seven sites at which the government either fully or partially funded assessment or removal actions to determine if the releases that occurred were the result of legacy issues or if they occurred under modern conditions. This data collection process yielded five sites, which EPA designated for further investigation to determine if the releases at the sites were relevant to risks at currently operating petroleum and coal products manufacturing sites. Those sites are: Benicia Valero Refinery (CAN000900063;United Energy (INN000610822); St. Rose Air Assessment (LAN000605343); Lake Charles NRG (LAN000607016); and Browns Island Chemical Spill (WVN000306615). EPA collected additional data in order to develop release case narratives for each of these sites. To assess whether the releases at those sites are potentially indicative of the risk profile at currently operating facilities, EPA then compared those case narratives with the regulations under which those sites were operating at the time of the releases. As part of its rulemaking effort, EPA collected information about the implementation dates and contents of federal environmental and safety regulations relevant to petroleum and coal products manufacturing facilities. At each of the five sites listed above, EPA investigated the relevant federal environmental and safety regulations that were in place at the time of releases EPA also reviewed state environmental and safety regulations relevant to petroleum and coal products manufacturing facilities. In order to focus its review, EPA selected a sample of states that comprised the 11 states with the highest number of petroleum refineries and coal products manufacturing facilities that in the aggregate constitute over 50 percent of the petroleum refineries and coal products manufacturing facilities in the United States. The states for which EPA collected regulatory information are: Texas, Louisiana, California, Alaska, Oklahoma, Utah, Washington, Wyoming, Pennsylvania, Illinois, 13 ------- and Virginia. Four of the five sites are in states for which EPA conducted a review of state regulations. For the remaining two sites, the standing federal policy at the time illuminates the implications and risks at petroleum and coal products manufacturing sites. 14 ------- 1) Benicia Valero Refinery Facility Name: Benicia Valero Refinery EPA Region/State: R9 - California EPA SEMS ID: CAN000900063 FRSID:110033145353 Contamination Dates: 5/5/2017 Operation Dates: 1968 - present Response Action Lead: Mixed Lead Expenditures: None Reported Site Background/Description: The Benicia Valero Refinery is an oil and gas refining site. Built in 1968, the site has undergone significant modifications and upgrades to become one of the most complex refineries in the United States. The refinery's products include propane, butane, California Air Resource Board (CARB) gasoline, ultra-low-sulfur diesel (ULSD), jet fuel, fuel oil, residual oil, and asphalt. Currently, CARB gasoline makes up about 70% of the refinery's total production, but it also produces a significant portion of northern California's asphalt supply. The facility occupies 800 acres in an industrial park on the Carquinez Strait, a tributary of San Francisco Bay, Benicia, Solano County, California. Businesses immediately surround the industrial park, with residential neighborhoods within one mile. Benicia has approximately 30,000 residents. On May 5, 2017, a power outage triggered a flaring event at the site, releasing sulfur dioxide into the air. Valero blamed the power company, Pacific Gas and Electric (PG&E), for the power outage but Superfund documents indicate Valero is the responsible party. Sulfur dioxide is an irritant smoke which causes acute respiratory issues. This significant release impacted the surrounding neighborhoods, including businesses, residences and schools. Solano County ordered a shelter-in-place for the city of Benicia. Sources differ on the duration and quantity of the release. The September 29, 2017 Pollution Report notes that flaring ceased at the site the same day flaring began. EPA's OSC response page for the Valero Benicia Refinery notes 50,000 pounds of sulfur dioxide were released from the refinery over two days. KQED, National Public Radio's Northern California branch, reports that the Valero Benicia Refinery flaring released 31,000 pounds of sulfur dioxide on May 5, 2017, the day of the power outage, but that it released a total of over 80,000 pounds of sulfur dioxide over several weeks as a result of the same power outage. By comparison, the refinery released an estimated total of 13,800 pounds of sulfur dioxide over the entirety of 2016, and 15,400 pounds of sulfur dioxide in 2015. An EPA spokesman quoted in a local news story stated that concentrations of toxic gases from the flares, such as hydrogen sulfide, peaked at 10 times normal background levels for the area. A report that Valero issued to the California Office of Emergency Services in June 2017 further indicated that monitoring did not show an increase in ambient sulfur dioxide levels outside the refinery site and that exposure to sulfur dioxide was limited to people at the refinery. 15 ------- Regulatory Compliance/Action/Response: On May 5, 2017, approximately one hour after the outage and subsequent flaring, warning systems were activated in Benicia. EPA's Superfund Technical Assessment and Response Team (START) arrived at the incident command post (ICP) at the Benicia Fire Department at 1115 hours. EPA START personnel integrated into unified command with representatives from Solano County and Valero Corporation and participated in all response decisions and communications throughout the day. At 11:30 AM, Solano County issued a shelter-in-place order for all areas of Benicia and advised businesses and structures downwind from the refinery to evacuate and for all persons to avoid the refinery area. START performed clearance sampling to assist with Solano County's Health Department decision-making regarding the shelter-in-place order. Bay Area Air Quality Management District and the California Air Resources Board also collected limited air samples in canisters for documentation. Valero Corporation conducted some monitoring and handled securing the response. START first performed air monitoring at two schools: Matthew Turner Elementary, located at 540 Rose Drive, and Robert Semple Elementary, located at 2015 E 3rd Street. The wind was blowing out of the west/southwest at approximately 15 to 20 miles per hour and both schools were located upwind of the flaring at the refinery. Using AreaRAEs to measure sulfur dioxide and hydrogen sulfide and a Personal DataRAM (PDR) to measure particulates, START monitored air at seven locations at each school beginning at 1145 hours. All seven locations at Matthew Turner Elementary measured readings of 0.0 parts per million (ppm) for sulfur dioxide, 0 ppm for hydrogen sulfide, and 0.015 milligrams per cubic meter (mg/m3) for particulates. All sampling locations at Robert Semple Elementary measured readings of 0.0 ppm for sulfur dioxide, 0 ppm for hydrogen sulfide, and particulates equal to or below 0.040 mg/m3. The Occupational Safety and Health Act (OSHA) permissible exposure limit (PEL) is 2 ppm for sulfur dioxide, 10 ppm for hydrogen sulfide, and 10 mg/m3 for particulates. Following the clearance of the elementary schools, START conducted air monitoring at 4201 Industrial Way in the Benicia Industrial Park, downwind of the flaring at the refinery. From this location, the smoke plume appeared to be descending onto Suisun Bay in the direction of the Ghost Fleet. Sulfur dioxide measured readings of 0.0 ppm, hydrogen sulfide measured 0 ppm, and particulates measured 0.070 mg/m3. At 1640 hours, flaring was not occurring. After this time, START conducted air monitoring at three locations in the Benicia Industrial Park using the AreaRAE and PDR. There were no visible smoke emissions from the stacks at the refinery at that time. At the first location, directly downwind of the flaring at corner of Stone Road and Getty Court, sulfur dioxide and hydrogen sulfide readings measured at background (0 ppm) and particulates measured at 0.012 mg/m3. At 1700 hours, START again monitored the location adjacent to 4201 Industrial Way. START observed hazy air and a slight sulfur/tar- like odor but no longer saw smoke descending on Suisun Bay. Sulfur dioxide and hydrogen sulfide readings were not detected above background and particulates ranged from 0.016 to 0.033 mg/m3. At 1725 hours, at the final location on the corner of Stone Road and Park Road, START noted a similar sulfur/tarlike odor. Sulfur dioxide and hydrogen sulfide readings did not measure above background and particulates readings were 0.043 mg/m3. The September 29, 2017 Pollution Report notes that flaring ceased at the site sometime before 1650 hours on May 5, 2017 and does not document EPA involvement at the site after May 5, the day flaring began. 16 ------- The Bay Area Quality Management District issued four notices of violation against Valero: three for excessive smoke and one for causing a public nuisance. Two investigations, by the California Division of Occupational Safety and Health and the Solano County Environmental Division, cleared Valero of wrongdoing. Benecia Valero has been the subject of three federal enforcement actions, one each in CAA, EPCRA and RCRA statutes. The inflation adjusted total enforcement values of these three cases is $200,533,304. The RCRA case concluded in March 2005, and involved the contaminants benzene, benzo(a)pyrene, chrysene, lead, chromium, and sulfuric acid. The November 2005 judicial CAA case was a Region 9 portion of EPA's national petroleum refinery initiative. It included violations at Valero Refining Company-California's Benicia Refinery and Ultramar, Inc.'s Wilmington Refinery. The violations were for new source review and prevention of significant deterioration requirements; new source performance standards codified at 40 C.F.R. Part 60, Subparts J, VV, GGG; and national emission standards for hazardous air pollutants codified at 40 C.F.R. Part 61, Subparts J, V, and FF, and Part 63, Subparts F, H, and CC. Finally, the September 2016 EPCRA case cited the facility for violations discovered during routine compliance evaluation inspections. Discussion - Applicable Federal Regulations and Ongoing Risk Profile: Modern environmental regulations were in place at the time of the 2017 release at this site. The National Ambient Air Quality Standards (NAAQS), 40 CFR Part 50, include primary and second air quality standards for sulfur dioxide and particulate matter. Sulfur dioxide was the principal contaminant released at the site. California's ambient air quality standards, 17 CCR 70100-70201, are more stringent than NAAQS for sulfur dioxide and particulate matter, and further establish standards for visible pollutants and hydrogen sulfide. Emissions of sulfur dioxide at petroleum refineries are governed by 40 CFR Part 60.104, within Subpart J, New Source Performance Standards (NSPS) for Petroleum Refineries. Under Part 60.104(f(a)), these standards do not apply to combustion in a flare that is released as a result of emergency malfunctions. EPA also monitored hydrogen sulfide. All the monitoring EPA conducted at and near the site measured during the 2017 release showed all sulfur dioxide, hydrogen sulfide, and particulates at or below background levels. Public media reports that the flaring event at this site also released the gas carbonyl sulfide. Carbonyl sulfide is a hazardous substance under 40 CFR Part 63, National Emission Standards for Hazardous Air Pollutants (NESHAPS), Subpart CC, which governs emissions at petroleum refineries. 40 CFR Part 63.655 of this subpart dictates hazardous air pollutant release reporting requirements. Carbonyl sulfide is also a hazardous and toxic chemical under the Superfund, Emergency Planning, and Community Right-to-Know Programs (40 CFR Parts 300-399). Release reporting of carbonyl sulfide is therefore also regulated under 40 CFR Part 302, Designation, Reportable Quantities, and Notification and 40 CFR Part 372, CERCLA Toxic Chemical Release Reporting. In addition to reporting requirements, the CERCLA rules specify emergency preparedness and response provisions for facilities handling toxic and hazardous substances. For example, 40 CFR Part 355, the CERCLA Emergency Planning and Notification regulation, requires disclosure of facility information to 17 ------- allow state and local authorities to develop and implement chemical emergency response plans. 40 CFR Part 370, CERCLA Hazardous Chemical Reporting: Community Right to Know, further establishes Material Safety Data Sheet (MSDS) and inventory reporting requirements for hazardous materials held over certain thresholds at a facility. Separately, 40 CFR Parts 63.670 and 63.671 dictate requirements for flare control and for flare monitoring systems, respectively. General emergency planning and response regulations also applied to the Valero Benicia Refinery at the time of the release. For example, employers are required to have Emergency Action Plans (EAPs) under the OSHA (29 CFR Part 1910). EAPs must include procedures for reporting a fire or other emergencies, procedures for emergency evacuation, and other procedures (29 CFR Part 1910.38 Subpart E). In 1977, the State of California promulgated 8 CCR 1, Subchapter 15, Petroleum Safety Orders - Refining, Transportation and Handling. These rules govern equipment maintenance, gas and vapor testing, and other safety practices at California petroleum refiners. 19 CCR Part 2631, Immediate Reporting of a Release or a Threatened Release, requires reporting or releases of hazardous materials to the California Emergency Management Agency. The Benicia Valley Refinery was thus subject not only to federal emergency planning, response, and reporting regulations, but also California regulations, at the time of the release. On October 1, 2017, five months after the flaring incident, the California Environmental Protection Agency implemented new California Division of Occupational Safety and Health worker safety regulations and California Accidental Release Prevention Program regulations. The regulations can be found at 19 CCR 2735.1, Chapter 4.5). Specifically with respect to refineries, the regulations increased employer accountability for the mechanical integrity of refinery equipment, requires refineries to adopt safer designs and systems, requires that refineries conduct investigations to determine the root causes of any incidents that occur and develop interim and permanent corrective measures, and require refineries to submit annual, public reports of safety metrics. Despite the significant release of contaminants that resulted from the flare, it does not appear that Valero Corporation violated any air quality standards as a result of the release. The only agency that noticed violations to Valero Corporation was the Bay Area Air Quality Management District; the violations were for excessive smoke and a public nuisance. While public press documents indicated significant public health concerns regarding the release, all sampling was below OSHA PELs. Further, it appears that Valero Corporation was compliant with all federal and state emergency response regulations. The only Pollution Report available for this site only describes the removal assessments and response actions that took place and does not describe or anticipate any future removal actions associated with this release. This review therefore demonstrates that modern environmental regulations applicable to the flaring event were in place at the time of the release, and that Valero Corporation was not in violation of these regulations. EPA therefore concludes that this non-NPL removal case represents an example of current risk within the petroleum and coal products manufacturing industry. Additionally, Valero Corporation handled the response and conducted monitoring in conjunction with EPA and Solano County, which indicates that the company bore at least some of the response costs at the site. 18 ------- References: • Pollution Report #1, September 9, 2017 • "New Regulations Improve Safety at Oil Refineries/' California Environmental Protection Agency, August 4, 2017.

The site operated under the names Troy Refining, Jarvis Refining Company, Somerset Oil, Inc., and United Energy. The site, built in the 1920s, functioned as a refinery, a petroleum distribution facility, and a gasoline station until the 1970s. There have been no operations at the site since the 1970s. The site is divided by State Road 66, and there is a public park between the abandoned refinery and Anderson Creek. United Energy obtained the site in 1980 and transferred it to Fremon Kline in 1996. A significant flood of the Ohio River occurred in 1997, which put 75 percent of the site underwater and exacerbated contamination. The Spencer County government obtained title to the site property from Fremon Kline in 2001. As of 2012, tar pits, waste oil lagoons, semi-buried storage tanks, above ground storage tanks (ASTs), abandoned drums, and debris were still present at the site. Many of the tanks had dark staining in the surrounding soil. EPA documented polychlorinated biphenyls (PCB) contaminated soils and the release of PCB oils that resulted from historic operations at concentrations which exceed levels that warrant a removal action. Analysis of the site contamination revealed that PCB concentrations in the soils were above TSCA remediation waste clean-up standards of 25 milligrams per kilogram, and elevated levels of PCB-1242 were found in the waste oils in the USTs. Ultimately, 6,000 gallons of PCB oils were found in the underground storage tanks (USTs) and 30,000 gallons of other waste oils in ASTs were found at the site. Significant levels of total petroleum hydrocarbons - gasoline range organics, total petroleum hydrocarbons - extended range organics, lead, selenium, mercury, benzene, ethylbenzene, xylene, n- hexane, naphthalene, and other petroleum related compounds were observed in soils at the site. Regulatory Compliance/Action/Response: In March 1997, the Immediate Removal Section of the Indiana Department of Environmental Management (IDEM) conducted a site assessment of the property in response to the flooding along the Ohio River. Approximately 75 percent of the property was underwater. A mass of floating oil sludge and heavy sheen of oil could be seen from the highway. IDEM observed the presence of former tars pits and waste oil lagoons, PCB stained soils, and PCB oils in two semi-buried horizontal tanks. Between March 20 ------- and July 1997, IDEM removed soils contaminated with petroleum and PCBs from the property. Oil, sludge from tanks and settling basins and 3,000 waste tires were removed from the site. In the summer of 2009, the Indiana 15 Regional Planning Commission, in conjunction with the site owner, Spencer County, contracted ATC Associates, Inc. (ATC) to perform a Phase I Environmental Assessment (ESA) of the site. The ESA was funded through a U.S. EPA Brownfield Grant. The ESA identified, documented, and evaluated environmental conditions. One year later, in the summer of 2010, ATC was retained by the Indiana 15 Regional Planning Commission to perform an Asbestos Investigation Report and a Phase II Limited Subsurface Investigation to further assess areas of concern that the 2009 ESA identified. None of the subsequent site response documents noted the presence of asbestos or the need to remove asbestos following the Asbestos Investigation Report. In July and August of 2011, ATC returned to the site to inspect the ASTs and USTs and collect representative samples of each tank's contents. As a result of ATC's assessments of the site, in August of 2012 EPA mobilized ERRS and START contractors to assist with the removal of PCB impacted oils contained in the ASTs and USTs and impacted soil at the site. The EPA contractors conducted clearing and grubbing activities at the site, removed liquids from the tanks, decommissioned and scrapped the ASTs and USTs, removed other debris found on site, removed petroleum impacted soils, and disposed of contaminated materials offsite. Spencer County aided the response activities by providing coal ash to solidify the contents of ASTs prior to removal. No federal enforcement actions were found at the United Energy site. Discussion - Applicable Federal Regulations and Ongoing Risk Profile The Toxic Substances Control Act (TSCA) at 40 CFR Part 761 (PCBs Manufacturing, Processing, Distribution in Commerce, and Use Prohibitions) regulates the handling and disposal of PCBs. EPA implemented 40 CFR Part 761 in 1979. Under the TSCA, United Energy, Fremon Kline, Spencer County, and any other owners and operators of the site were responsible for determining the concentration of PCBs in the storage tanks being stored on site and the PCBs that contaminated soils at the site. The site owners and operators failed to manage the PCB wastes and PCB contamination in compliance with the TSCA. Upon acquiring the site, United Energy and subsequent owners and operators were required to dispose of the PCB liquids in the ASTs and USTs in accordance with 40 CFR Part 761.60. TSCA requires that facilities dispose of PCB waste within one year of the date when the facility placed the waste in storage. None of the owners or operators of the site since 1980 complied with these regulations. In 1998, Subpart D of the 40 CFR Part 761, which regulates the disposal and storage of PCB materials, underwent substantial revisions and additions. Provisions added at this time further governed how the facility owners should have cleaned up the site. For example, 40 CFR Part 761.79 sets forth decontamination standards and procedures for PCB containers. 40 CFR Part 761.61 governs the cleanup and management of PCB waste generated as the result of PCB spills. With respect to the PCB soil contamination, the owners and operators of the site failed to follow TSCA regulations at 40 CFR Part 761.125. That subpart requires sampling of PCB concentrations present in the spill and categorizes responses the spill based on PCB concentrations and total weight spilled. Spills that exceed one pound 21 ------- or more of PCBs by weight necessitate the owner or operator report the spill to the National Response Center. Spills that exceed ten pounds or more of PCBs by weight require the owner or operator to notify the EPA regional office about the spill, cordon off or delineate the area, record the area of visible concentration, and remove visible traces of the spill fluid and affected media. Based on the total amount of PCB liquids found at the site in the storage tanks, it is possible that the contaminated soil at the site contained at least ten pounds of PCBs by weight, which meant these regulations would have applied to the site. Additional standards and practices are in place under 40 CFR Part 761.125 for spills that contaminate surface water, sewers, or drinking water, and it appears these practices may have applied to the site, as well. None of the owners and operators at the site since 1980 complied with these regulations. Removal actions at the site were also required under the Resource Conservation and Recovery Act (RCRA), which states that facilities must remove, treat, or dispose of PCB waste within one year of the date when the facility placed the waste in storage. RCRA regulations with respect to the storage of PCB wastes were effective on July 8, 1987 (52 FR 25791). United Energy was the owner of the site at that time, and Fremon Kline and Spencer County were subsequent owners of the site. Additionally, the Standards for Owners and Operators of Hazardous Waste Treatment Storage, and Disposal Facilities, 40 CFR Part 264-265, establishes minimum national standards defining acceptable hazardous waste management. Part 265 of Hazardous Waste Management and Disposal outlines general facility standards, preparedness and prevention, recordkeeping and reporting, ground-water monitoring system, closure and post-closure plans, use and management of containers, tanks, and more. Effective since May 19, 1980 required the owners of the site to safely dispose of PCB and other hazardous waste. RCRA regulations under 40 CFR Part 268, Subpart E require that prohibited wastes, including PCBs, be stored in containers at disposal facilities and may only be stored to facilitate their property recovery, treatment, and disposal. The subpart prohibits storage of PCBs for more than one year, unless storage is necessary to accumulate sufficient waste to facilitate recovery, treatment, or disposal. Further, the subpart requires that liquid hazardous wastes containing PCBs at concentrations of above 50 parts per million are stored in proper facilities and treated or disposed within one year of storage. These regulations were effective as of November 8, 1986, and all of the owners subsequent to that date stored PCB liquids for longer than one year at the site and failed to treat or dispose those liquids. It appears that the legacy PCB contamination at the site was associated with historical operations. This review demonstrates, however, that contamination continued and worsened because owners of the site were not in compliance with relevant regulations for PCB storage, disposal, and contamination. EPA did not review Indiana state environmental and safety regulations relevant to petroleum and coal products manufacturing.

The site is currently under the corporate names Equilon Enterprises LLC, Shell St Rose, and IMTT. This facility is located within the IMTT campus in St. Rose at 11842 River Road (29.9385° N, 90.3301° W) and primarily processes bitumen to produce asphalt. Residential homes, industrial facilities, an IMTT tank farm, forested swamp area, and the Mississippi River surround the facility. The residential neighborhoods extend approximately 0.24 miles to the east of the facility and 0.15 miles to the west of the facility. Around 130 people from these neighborhoods complained of sulfurous odors and resulting illness emanating from the Shell Refinery and IMTT Joint Bitumen Project beginning June 8, 2014. The Louisiana Department of Environmental Quality (LDEQ) investigated these complaints and documented the presences of sulfur and petroleum odors. LDEQ interviewed personnel from the facility and determined that a malfunction in a regenerative thermal oxidizer (RTO) used by the facility to remove sulfur compounds and organic vapors from its exhaust resulted in the odors and emissions. IMTT/Shell and LDEQ identified the use of a high bitumen crude oil not normally used in IMTT/Shell's processes for creating asphalt compounds as a potential cause of the malfunction. The facility addressed the RTO issues and removed the high bitumen crude from the site, and LDEQ noted that the odors receded within one week. St. Rose residents continued to complain of odors and health problems at least into May 2015, leading LDEQ and EPA to establish an air monitoring program in St. Rose. Regulatory Compliance/Action/Response: In October 2012, Shell Chemical St Rose was the subject of a CAA federal judicial enforcement case. The 2017 inflation adjusted total enforcement value of this case is $3,133,728. The case was a Region 6 portion of EPA's national petroleum refinery initiative. It included violations at Shell Chemical petroleum refineries in Saraland, Alabama and St. Rose, Louisiana. The Consent Decree also resolved separate but related state law claims brought by co-plaintiffs Alabama and Louisiana. It resolved allegations asserted in complaints filed under Section 113(b) of the Clean Air Act, 42 (JSC 7413(b). In addition to the payment of civil penalties, the settlement required Shell to perform injunctive relief to reduce emissions of nitrogen oxides, sulfur dioxide, volatile organic compounds, and benzene. 23 ------- More recently, after the initial reports of odor and illness in June of 2014, LDEQ investigated the emissions causing these issues and identified the malfunctioning RTO at the Shell Refinery and IMTT Joint Bitumen Project. Shell and IMTT acknowledged its facility released emissions over ten days in June. LDEQ, in coordination with EPA R6, directed Shell IMTT to perform maintenance on the malfunctioning RTO and remove the waste generated by the cleanup of the RTO. At the end of September 2014, LDEQ, Shell and IMTT, and St. Charles Parish officials met with St. Rose residents, many of whom continued to report health issues from emissions from the facility. In October of the same year, in response to ongoing community mobilization, complaints, and health concerns of residents, including plans to rally at the Shell/IMTT facility, the LDEQ requested assistance from EPA to conduct air monitoring in St. Rose. Upon receiving the LDEQ's request to assist in the assessment of air quality, the EPA began discussing monitoring capabilities and logistics. LDEQ compiled a monitoring and sampling plan for hydrogen sulfide (H2S) and VOC monitoring at 18 locations in the area of concern. The monitoring and sampling plan detailed air monitoring to be conducted with Summa canister at one or more of the monitoring locations each day, as determined by the LDEQ's Project Leader. Additionally, the plan called for LDEQ to monitor air at four-hour intervals at the 18 locations over two weeks. After reviewing the plan and discussing project objectives with the LDEQ, the EPA agreed to independently check H2S and VOC levels at each of the monitoring locations during the last four days of the LDEQ assessment. If monitoring results exceeded action levels (70 ppb for H2S and five ppm for VOCs) at any locations, EPA agreed to collect 24-hour air samples using Summa canisters at the locations where the exceedance was detected and at an upwind location. LDEQ met with community leaders to communicate this plan and its objectives prior to initiating the air assessment program. On October 31, 2014 an EPA representative mobilized to the site to meet with the LDEQ Project Leader and a resident who granted access to private property for deployment of an air monitoring instrument. EPA and LDEQ also reviewed and discussed the other monitoring locations, the history and issues which prompted the response, and EPA's plan to mobilize to the site on November 3 at 0830. The EPA mobilized to the site on Monday, November 3, 2014 at 0830 and deployed Honeywell Single Point Monitors (SPM) with low level H2S specific sample media at two locations: the American Legion Hall near the Oaklawn subdivision west of the facility (monitoring point 15) and a Preston Hollow residence east of the facility (near monitoring point 7). The SPMs were programmed to alarm at a low- level setting of four ppb and a high-level setting of 80 ppb over a four-day period. After placing the SPMs, EPA began air monitoring at the LDEQ monitoring points using a Jerome H2S Analyzer to detect hydrogen sulfide and a MultiRAE monitor to detect VOCs. EPA recorded monitoring information along with any observations related to the monitoring activities on field data sheets. Monitoring of all 18 LDEQ points was completed approximately once every 34 hours and continued throughout the day and night. Personnel detected hydrogen sulfide in exceedance of the 70 ppb action level at location 12 at approximately 0630 on Tuesday, November 4. Location 12 sits at the north end of 4th Street near St. Charles Parish's wastewater and stormwater lift stations. EPA used a Summa canister to sample six liters of air over a 24-hour period at both location 12 and the American Legion Hall upwind of location 12. Air monitoring continued throughout the day and night, and no other exceedances were detected. 24 ------- On Wednesday, November 5, personnel again detected a H2S exceedance at location 12. After the 24- hour sample period, EPA collected the Summa canisters deployed on November 3 and deployed new canisters to the same locations to collect air samples over the next 24 hours. Air monitoring activities continued throughout the day and night, and no other exceedances were detected. On Thursday, November 6, EPA continued to conduct air monitoring activities and collected the Summa canisters from location 12 and the American Legion Hall. During this operational period, EPA personnel interviewed a St. Charles Parish wastewater maintenance representative to determine the operation and design of the wastewater lift station near location 12. The representative provided access to the lift station and information on its functions. The lift station is comprised of two large pumps, piping, and a below ground concrete sump. Wastewater flows into the sump until it reaches a specific level which activates the pumps to lift the material from the sump via the associated piping. The wastewater representative lifted the manhole cover and allowed the EPA to conduct air monitoring at the opening. EPA personnel detected 30 ppm H2S and documented possible cross contamination from the lift station. Thursday afternoon, EPA and LDEQ met with a Parrish official to discuss the assessment and delivery of the final report. The official did not express any concerns and requested that both EPA and LDEQ attend a future community meeting to report the results of the assessment. Air monitoring activities continued throughout the day and night, and no other exceedances were detected. On Friday November 7, 2014, the EPA concluded air monitoring activities at 0800 hours. Air samples were shipped to ALS Laboratories in Simi Valley, CA. All equipment and personnel demobilized from the site by 1030. EPA planned to compile and send the information gathered during the response to LDEQ for inclusion into a comprehensive assessment report. LDEQ assumed responsibility for distributing all data and information regarding this assessment to the public. EPA did not conduct any enforcement activities. The Shell Refinery and IMTT Joint Bitumen Project was identified as a potentially responsible party. In June 2014, Shell and IMTT released a joint statement asserting all emissions for its St. Rose Bitumen Project facility met EPA air quality standards according to sampling conducted by LDEQ. The companies also stated at this time that they were working to install additional odor control equipment and improve their process for notifying state and local officials. In May of 2015, residents conducted a rally outside of the facility and continued to complain of health concerns as a result of its emissions. Discussion - Applicable Federal Regulations and Ongoing Risk Profile: The primary pollutant of concern at this site was hydrogen sulfide. EPA also monitored VOCs but did not measure any exceedances. According to the Occupational Safety and Health Administration (OSHA), hydrogen sulfide is a "colorless, flammable, and extremely hazardous gas" which occurs naturally in crude petroleum. Repeated exposure to hydrogen sulfide can result in adverse health impacts ranging from irritation of the eyes and respiratory system to convulsions and asphyxiation, depending on the exposure concentrations. According to local media reporting, Shell and IMTT admitted to releasing emissions over ten days in June 2014 but claimed these emissions did not lead to any exceedance of state-wide regulations. Federal regulations do not establish ambient air criteria for hydrogen sulfide; neither the National Ambient Air 25 ------- Quality Standards (NAAQS, 40 CFR Part 50) nor the National Emissions Standards for Hazardous Air Pollutants (NESHAPS, 40 CFR Part 63) include standards for hydrogen sulfide. The state of Louisiana regulates ambient air concentrations of hydrogen sulfide under LAC 33: III 51, Comprehensive Toxic Air Pollutant Emission Control Program, effective in December of 1991. In addition to adopting the federal NESHAPS, this Chapter sets ambient air standards for toxic air pollutants in Part 5105 and Table 51.2. Under this rule, the eight-hour average of ambient air concentrations of hydrogen sulfide may not exceed 330 ug/m3 (approximately 230 ppm). The response documents do not describe any air monitoring performed by LDEQ or EPA at the time of the initial release in June 2014. EPA therefore cannot conclude if the June release violated Louisiana regulation. The highest reading of hydrogen sulfide registered during the EPA's November 2014 monitoring efforts was 30 ppm at the lift station near location 12. Though EPA did not document any exceedances of federal or state ambient air quality regulations from the Shell Refinery and IMTT Joint Bitumen Project between June and November of 2014, releases of sulfide were reportable under several federal and Louisiana state laws at the time of the incident in June 2014. Hydrogen sulfide is a hazardous and toxic chemical under the federal Superfund, Emergency Planning, and Community Right-to-Know Programs (40 CFR Parts 300-399). 40 CFR Part 302.4 (Designation of hazardous substances), requires reporting of hydrogen sulfide releases of 100 pounds or more. 40 CFR Part 372, CERCLA Toxic Chemical Release Reporting, requires reporting of releases of toxic substances, including hydrogen sulfide, of any quantity from applicable facilities. 40 CFR Part 372.23 (SIC and NAICS codes to which this Part applies) and 40 CFR Part 372.25 (thresholds for reporting) indicate the facilities to which this regulation applies. As a petroleum and coal manufacturing facility (NAICS 324), the Shell Refinery and IMTT Joint Bitumen Project facility was required to report the 2014 hydrogen sulfide release under 40 CFR Part 372.23. 40 CFR Part 372.25 requires release reporting for facilities using 10,000 pounds or more of the hydrogen sulfide. Response documents indicate that the Louisiana Department of Environmental Quality learned of the June 2014 release from St. Rose community members rather than from Shell and IMTT, suggesting the companies may not have reported the release. In addition to these reporting requirements, the Shell Refinery and IMTT Joint Bitumen Project facility was also subject to the federal Chemical Accident Prevention Provisions (40 CFR Part 68), adopted by Louisiana in LAC 33: III 59 (Chemical Accident Prevention and Minimization of Consequences). These regulations require and/or set guidance for the prevention and detection of accidental releases of hazardous substances including hydrogen sulfide (as set forth in 40 CFR Part 68.130) from stationary sources of over certain threshold amounts of the subject substance. The rules address the use, operation, repair, and maintenance of equipment to monitor, detect, inspect, and control releases, including the training of personnel. Subchapter G of this Part includes the requirement for regulated facilities to submit Risk Management Plans (RMPs), comprising hazard assessments, prevention programs, and emergency response programs. The Shell Refinery and IMTT Joint Bitumen Project may have been in violation of these regulations. Finally, the Occupational Safety and Health Administration regulates hydrogen sulfide as a highly hazardous substance under 40 CFR Part 1910. These rules prohibit worker exposure to hydrogen sulfide and other toxic and hazardous substances over 20 ppm or over 50 ppm if no other measurable exposures occur within an eight-hour period. While EPA was not involved with sampling at the time of the acute hydrogen sulfide release in June of 2014, monitoring efforts in October 2014 measured 26 ------- hydrogen sulfide at 30 ppm, suggesting concentrations could likely have been above OSHA permissible exposure limits (PEL) during the release cause by the RTO malfunction. This review demonstrates that modern federal and state ambient air quality standards, toxic release reporting requirements, worker safety rules, and emergency response and preparedness regulations were in place and applicable to the 2014 hydrogen sulfide emissions releases. It further demonstrates that the IMTT and Shell Joint Bitumen Project likely violated toxic reporting and worker safety regulations and may also have violated ambient air quality and emergency response and preparedness rules. EPA therefore concludes that this non-NPL removal case represents an example of current risk within the petroleum and coal products manufacturing industry.

Undeveloped, wooded lots border the site on the north, east, and west. Commercial and light industrial activity zones are in the area surrounding the site. The site is also approximately 2,500 feet from the closest residential properties. Refinery operations occurred at the site from 1983 to 1999. The refinery operations consisted of salvaging petroleum feed stocks into naphtha, number 2 fuel oil, and residual fuel oil. Rebel Energy, Inc. constructed the site in 1983 and sold it to Westate, Inc. 1989. Westate, Inc. subsequently filed for bankruptcy in 1994. National Resources, Inc. acquired the site in 1996 and operated it as the National Resources Refinery, although some site materials indicate that National Resources, Inc. leased the site with an option to purchase that it never exercised; National Resources, Inc. entered involuntary bankruptcy in 2001. The site was then transferred to NRG in 1998. Site operations ceased in 1999, and remediation and removal have been the only site activities since 2000. In 2003, Primergy International, LLC expressed the intention to purchase the property, but the sale never went through. The Calcasieu Parish Police Jury adjudicated the property on back taxes in 2008, and Calcasieu Parish currently controls the property. Of the former non-governmental owners of the site, no viable PRPs were identified. The site contains a refinery plant, 24 above ground cylindrical steel tanks, two frac-tanks, two sludge boxes, a tractor trailer truck with attached tank trailer, nine poly tote tanks, one rectangular wastewater treatment steel tank, 25 steel and poly drums, and a roll-off box. Secondary containment structures are in place around the tanks, though site reports note that those containment structures are leaking. A 2010 site visit discovered that a tank had failed, and oil was leaking from the containment structure surrounding its tank farms. It appeared that containment liquid had overflown onto the adjacent property north of the site. Subsequent site inspections uncovered oil staining at a second tank farm due to the failure of another tank. Tanks and drums at the site contained approximately 200,000 gallons of hazardous liquids. These liquids were an oily-water mixture and included volatile and semi-volatile organic compounds (VOCs). Samples collected from the vertical tanks and frac-tanks at the site detected VOCs at concentrations in the percent range, specifically for naphthalene. Hazardous sludge and an additional hazardous acid liquids were present at the site. Analysis of soil at the site reflected contamination by Total Petroleum Hydrocarbons (TPH), Poly-Aromatic Hydrocarbons (PAH), and VOCs. 28 ------- These contaminants were present in the soil at levels deemed to require removal but were not classified as hazardous. Regulatory Compliance/Action/Response: During a January 25, 2010 site visit by representatives from EPA and the Louisiana Department of Environmental Quality, a layer of oil was discovered in the containment structure for one of the tank farms (900 series tanks), with evidence that the containment had overflown onto the property north of the site, due to the failure of one of the three tanks in the tank farm. During sampling for characterization of the site for NPL assessment conducted in May 2010, oil staining was found in a second tank farm (400/500 series tanks), due to failure of an additional tank. An NPL site assessment determined the site is not eligible for NPL ranking. Secondary containments continued to collect rainwater and overflow liquids potentially containing oil or waste from leaking tanks. Ultimately, the assessment determined that the tanks and drums contained approximately 200,000 gallons of hazardous substances (not including the liquids in the secondary containments). The following year, on February 14, 2011, EPA mobilized to the site to begin emergency stabilization. Emergency removal action (stabilization) is a temporary step to prevent the ongoing release of hazardous substances from the site and prevent unimpeded access to the property. From February 15 to February 18, 40,000 gallons of contaminated liquid was removed from the secondary containments, open drums, and sumps. EPA also conducted sampling for disposal profiling on February 17 and 18. Site stabilization activities concluded on February 18, 2011. EPA activities restarted at the site in July 2011 and continued through March 2012. Site work included the re-gauging of tanks and collecting oil and sludge samples prior to off-site disposal. EPA removal actions transported 220,803 gallons of hazardous liquids, 240 cubic yards of hazardous solid sludge, and 4,375 gallons of hazardous acid liquids. Additionally, EPA removed 49,456 gallons of non-hazardous contaminated water, 39.4 tons of naturally occurring radioactive material debris, 190 cubic yards of non- hazardous debris, 576 cubic yards of non-hazardous soils, and 591,360 pounds of scrap metal for off-site disposal and/or recycling. The tanks, process equipment, and ancillary tank piping at the site were cut, pressure washed, and removed. Once EPA removed hazardous material from on-site tanks and associated equipment, those tanks were decontaminated and sent off-site as scrap metal. EPA also decontaminated the containment structures at the site to prevent additional rainwater contamination. The removal of the 100/200 series tanks uncovered stained soil in the tanks' footprint. EPA excavated and stockpiled the top layer of the affected soil. EPA sent samples of the soil for analysis for disposal preparation and contamination assessment. EPA also collected soil samples from other areas of concern at the site. The samples contained low levels of TPH, PAH, and VOC contamination. The contamination necessitated removal and disposal of the affected soil but did not classify the soil as hazardous material. EPA ultimately removed 576 cubic yards of this non-hazardous, contaminated soil. The tanker truck and tanker trailer remained on site, but EPA removed the contents and a vendor cleaned and decontaminated the tanker. No federal enforcement actions were found at the Lake Charles NRG site. 29 ------- Discussion: Applicable Federal Regulations and Ongoing Risk Profile In 1980, the Standards for Owners and Operators of Hazardous Waste Treatment, Storage, and Disposal Facilities went into effect through the Resource Conservation and Recovery Act (RCRA). For the following 19 years, additional regulations were added that, had Lake Charles NRG owners and operators followed, would have mitigated the extent of the contaminations. Effective since 1981, 40 CFR Part 264, Subpart I, requires owners and operators of hazardous waste facilities to keep containers closed, ensure containers are handled and stored in such a manner to avoid rupture or leakage, and conduct weekly inspections. At closure, all hazardous wastes and hazardous waste residues must be removed from the containment system and containers must be decontaminated. In 1992, Subpart DD of the 40 CFR Part 264, which establishes design and operating standards for containment buildings that treat or store hazardous waste, went into effect. The regulation requires owners and operators of facilities with containment buildings to remove or decontaminate all waste residues, containment system components, subsoils, and structures and equipment contaminated with waste or leachate, and manage them as hazardous waste. Owners and operators must generate closure plans and cost estimates, perform closure activities, and acquire financial responsibilities for containment buildings. If owners and operators cannot remove or decontaminate contaminated components, subsoils, structures, and equipment, they must close the facility and perform post-closure care, including acquiring financial responsibility. The owners of Lake Charles NRG, since 1992, failed to comply with these regulations. RCRA regulations under 40 CFR Part 268, Subpart E require that prohibited wastes, be stored in containers at disposal facilities and may only be stored to facilitate their property recovery, treatment, and disposal. The subpart prohibits storage of prohibited wastes for more than one year, unless storage is necessary to accumulate enough waste to facilitate recovery, treatment, or disposal. These regulations were effective as of November 8, 1986, and all of the owners subsequent to that date stored hazardous wastes in tanks and drums on site for longer than one year and failed to treat or dispose those liquids. Finally, the owners and operators of Lake Charles NRG did not follow closure and post-closure requirements which apply for 30 years after closure and include implementation of closure standards, implementation of closure plan, and time allowed for closure activities. Owners and operators much also submit a post-closure plan, post-closure property use and care guidelines, and notification and security requirements if hazardous waste remains on the facility after post-closure period. These regulations were effective as of October 29th, 1986 per 42 U.S.C. 6905, 6912(a), 6924, 6925, 6935, 6936, and 6937 under RCRA. The regulations establish guidelines for disposal or decontamination of equipment, structures, and soils. Upon completion of closure of a hazardous waste disposal unit, owners and operators must submit a certification of closure to the EPA regional office. This is yet another regulation with which Charles Lake NRG owners and operators failed to comply, contributing to the site contamination and necessitating the removal actions. Louisiana has a suite of hazardous waste regulations at LAC Title 33 Part V that largely adopt the federal regulations relevant to this site. Additionally, LAC Title 33 Part V Chapter 15 establishes siting requirements for the construction of hazardous waste facilities that includes regulations applicable to onsite discharges and preparedness and prevention. These regulations were effective in 1984, the year after the Lake Charles NRG plant went into operation. Given the abandonment, tank failures, and 30 ------- contamination related to leaks that occurred at the Lake Charles NRG site, it appears that the site's owners and operators were not in compliance with these state regulations. Several owners and operators at the Lake Charles site entered bankruptcy proceedings both during the site's operation and after its closure. As a result, EPA was unable to locate any viable PRPs to aid with removal actions at the site. It therefore appears that contamination occurred at the site under the modern environmental regulatory regime at both the federal and state level, and bankruptcies shifted the cost of the removal action at the site to the taxpayer.

It is located on Browns Island in the Ohio River in Weirton, West Virginia. The facility is currently owned by Arcelor Mittal Tecumseh Redevelopment Corp. (Arcelor), which was in the process of facility demolition and environmental cleanup activities at the time of the spill. Asbestos abatement activities were ongoing for several months prior to the chemical spill. Two previous issues at the site (coal tar tanks and a Prussian blue release) had resulted in corrective actions with the US EPA. The facility is listed in CERCLIS as the National Steel Corp (WVD980538607). The facility is accessed from a backwater bridge on the west side of the river, in Costoni, Ohio. On Thursday, March 20, 2008, Arcelor Mittal Tecumseh Redevelopment Corp. contacted the National Response Center (NRC, report # 865550) to report a spill of approximately 300 gallons of an unknown liquid at the facility. Analytical results from the tank's material indicated the largest constituents of the leaked material were naphthalene at 20,600 ppm, 1,2,4 trimethylbenzene at 9,240 ppm, and total xylenes at 3,380 ppm. The tank was actively leaking from a weld of saddle support and the spill path extended approximately 25-30 feet away from the leak, reaching water puddles along the south end of process area. Regulatory Compliance/Action/Response: EPA arrived on scene at about 1345 hours on March 20, 2008 and met with a representative from the Arcelor. An emergency response and environmental cleanup contractor hired by the PRP was on scene and had already laid out absorbent pads around the pooled areas of spilled liquid. West Virginia Department of Environmental Protection (WVDEP) representatives arrived later. EPA noted the leaking tank was labelled #36 and painted with lines and arrows. EPA used a Raytec noncontact thermometer to record a ten-degree difference approximately one foot from the top of the tank. The PRP at first believed the tank to be empty. However, upon inspection, the PRP contractor determined approximately two feet of material remained in the tank. A vacuum tanker was ordered to offload the remaining material from tank #36. The following day, March 21, 2008, EPA returned to the site to document the progress on spill containment and recovery. The PRP contractor had transferred approximately 1,100 gallons of liquid from tank #36 to tank #143 as an emergency temporary storage measure. Tank #143 was secure, not 32 ------- leaking, and in relatively better shape than tank #36, but its valve area showed signs of deterioration and past spill events. The contractor also moved tank #36 from the spill area, scraped the spill area, placed contaminated soil into a covered roll off present on site, and covered the spill area in plastic. In a low area of the original tank location where the saturated soils had begun to seep out liquid material, the contractor set up an earthen berm. EPA took no further action for this site. Arcelor disposed of the material and continued securing the site, while WVDEP continued to investigate conditions at the facility. Although there were extensive federal enforcement activities at National Steel, no federal enforcement actions were found at the Browns Island site. Discussion - Applicable Federal Regulations and Ongoing Risk Profile: Naphthalene, xylenes, and 1,2,4 trimethylbenzene were the primary constituents of the liquid in the tank that spilled. The Resource Conservation and Recovery Act (RCRA) defines hazardous wastes through 40 CFR Part 261, which was effective November 19, 1980. That regulation designates both naphthalene and xylenes as hazardous wastes. The facility's generation and storage of hazardous wastes meant that a suite of RCRA regulations applied to its waste handling, storage, and disposal, including the liquid that ultimately spilled in the 2008 incident. Effective since 1981, 40 CFR Part 264, Subpart I, requires owners and operators of hazardous waste facilities to keep containers closed, ensure containers are handled and stored in such a manner to avoid rupture or leakage, and conduct weekly inspections. At closure, all hazardous wastes and hazardous waste residues must be removed from the containment system and containers must be decontaminated. It appears that both Weirton Steel and Arcelor failed to comply with this regulation. Subpart J of 40 CFR Part 264, which was effective as of January 12, 1987, addresses the storage of hazardous waste in tank systems, such as the tanks present at the Browns Island Chemical Spill site. The regulations under Subpart J require facility owners and operators to assess the integrity of existing tank systems that do not have a secondary containment structure to determine that the tank system is not leaking and is fit for use. Because the leak at the site traveled directly to the surrounding soil, it does not appear that a secondary containment system existed for the tank storing the spilled substance. As a result, it appears that, depending on the time of the transfer of ownership of the facility, at least one of - if not both - Weirton Steel and Arcelor did not comply with this regulation. Subpart J of 40 CFR Part 264 also establishes requirements for responses to leaks or spills from hazardous waste storage tank systems at 40 CFR Part 264.196. It requires owners and operators of a facility that experiences a leak from a tank to remove the tank from use, contain any visible releases to the environment, and report the leak to EPA. Arcelor's conduct following the leak appears to have put it in compliance with this section of Subpart J. RCRA regulations under 40 CFR Part 268, Subpart E require that prohibited wastes, be stored in containers at disposal facilities and may only be stored to facilitate their property recovery, treatment, and disposal. The subpart prohibits storage of prohibited wastes for more than one year, unless storage is necessary to accumulate enough waste to facilitate recovery, treatment, or disposal. These 33 ------- regulations were effective as of November 8, 1986. It is unclear when ownership of the facility was transferred from Weirton Steel, but at least one of Weirton Steel and Arcelor and possibly both entities stored hazardous wastes in tanks and drums on site for longer than one year and failed to treat or dispose those liquids. Naphthalene and xylenes are also designated as hazardous substances under 40 CFR 302. Regulations under this part were effective April 4, 1985, and were implemented under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). In addition to hazardous substance designation, 40 CFR Prat 302 also establishes reporting requirements for releases of hazardous substances above certain reportable quantity thresholds. If releases contain hazardous substances in amounts above reportable quantities, the regulations require the facility owner or operator to immediately notify the NRC. With respect to the Browns Island Chemical Spill site, it does not appear that the amount of naphthalene or xylene in the 300-gallon spill exceeded the reportable quantity for either substance. Nonetheless, Arcelor, the current owner of the Browns Island Chemical Spill site, contacted the NRC after it discovered the spill, which would have put the facility in compliance with 40 CFR 302 had the spill contained reportable quantities of a hazardous substance. Thus, while it appears that Arcelor complied with modern environmental hazardous substance release reporting regulations under CERCLA, neither Arcelor nor the site's previous owner, Weirton Steel, complied with the hazardous waste storage, maintenance, and disposal regulations under RCRA. Additionally, while Arcelor did move the hazardous waste from the leaking tank to a secure tank, EPA response personnel noted that the new storage tank's valve area showed signs of deterioration and past spill events, potentially putting Arcelor in violation of 40 CFR Part 264, Subparts I and J, with respect to insuring the integrity of hazardous waste storage systems.
