On behalf of 3M, in June 2012, Exponent, Inc. collected surface water and sediment samples from a thirty-three mile stretch of the Tennessee River (River) in the vicinity of Decatur, AL. This work also included sampling of certain tributaries to the River for the same matrices and an evaluation of historical and current information on industrial and other sources of perfluorinated chemicals to the River in this area aside from the 3M Decatur facility. The results from this study have been compiled and summarized in the enclosed report. Surface water data for this portion of the Tennessee River has been previously generated and submitted to the subject docket. For certain analytes and locations, the enclosed report includes data that "overlaps" with previous study results. In such instances, the current data is consistently lower than the historical results. It should be noted that the enclosed report also includes data for certain analytes and locations that have not been included in previous 3M sampling campaigns. While 3M does not believe that any of these data taken alone or cumulatively meet the "substantial risk" reporting threshold, we nevertheless recognize the ongoing work by U.S. EPA to assess fluorochemical exposure pathways. Therefore, we are placing these results in the 8(e) docket as a supplement to previous submissions. If you have any questions, please contact Deanna Luebker at 651-737-1374 or djluebker@mmm.com.

The research included the evaluation o f historical and current information on industrial and other sources o f perfluorinated chemicals (PFCs) to the Tennessee River (river) in the Decatur area aside from the 3M Decatur facility. Historical PFC data from previous sampling o f surface water and sediment were also evaluated. In addition, surface water and sediments from the Tennessee River and its tributaries were collected and analyzed to provide a current view of the PFC concentrations that could have been affected by nearby sources, other than the 3M Decatur facility. Approximately 30 potential sources were identified including the following: Publically-owned wastewater treatment plant effluent. Decatur Utilities wastewater treatment plant (WWTP) and City o f Moulton WWTP discharges. Effluent from the Decatur Utilities WWTP sampled in 2005 contained a perfluorooctane sulfonate (PFOS) concentration o f 2,850 nanograms per liter (ng/L) (parts per trillion) and a perfluorooctanoic acid (PFOA) concentration of 17,400 ng/L. One year later in 2006, effluent from the Decatur Utilities WWTP contained a PFOS concentration o f 571 ng/L and a PFOA concentration o f 7,080 ng/L. In 2011, PFOA and PFOS in wastewater discharged from the Moulton WWTP ranged from 1,240 to 9,860 ng/L and 619 to 5,440 ng/L, respectively. Releases from agricultural areas where Decatur Utilities sludge had been land-applied. PFOS and PFOA were detected in soil and surface water sampled at some o f these agricultural areas by the U.S. Environmental Protection Agency (EPA) in 2008 and 2009. PFOS was detected in soil from 715 to 1,409 nanograms per gram (ng/g) (parts per billion), and PFOA was detected in soil from 818 to 2,531 ng/g. In surface water, PFOS ranged from undetectable to 66.3 ng/L and PFOA ranged from undetectable to 750 ng/L. 1203477 000 0201 1112KW08 VI November8, 2012 Releases from landfills where Decatur Utilities sludge had been disposed. Landfills that received sludge for disposal include Morris Farms Landfill and Morgan County Regional Landfill. PFOS and PFOA in leachate generated at these landfills have ranged from 43,200 to greater than 55,000 ng/L and from 48,700 to 91,600 ng/L, respectively. The abandoned hazardous waste site of Biological Processors of Alabama (BPA). In 2009, PFOS and PFOA were detected in waste liquids stored on the property. The maximum concentrations of PFOS and PFOA detected were 76.000 ng/L and 2,400 ng/L, respectively. PFOS and PFOA were also detected in a drainage pathway from the BPA site. Surface water collected from this drainage, upgradient o f BPA, had concentrations of PFOS and PFOA o f 15,100 and 29,000 ng/L, respectively. In contrast, a surface water sample collected downgradient of BPA had concentrations o f PFOS and PFOA o f 279,000 and 128.000 ng/L, respectively. Releases from BPA could have contributed to these elevated concentrations; however, more focused sampling is needed to evaluate the relative contribution o f the BPA site compared to the former sludge application fields located on 3M property. Surface water and/or groundwater releases from Daikin America/MDA Manufacturing and Toray Fluorofibers. Between December 2008 and December 2011, PFOA was detected between 4,540 and 307,000 ng/L in effluent discharged from Daikin America to Bakers Creek. Daikin America's National Pollutant Discharge Elimination System permit was recently modified in May 2012 to include quarterly monitoring o f PFOS. In September 2012, PFOS was detected between 27,000 and 60,000 ng/L in effluent discharged from three outfalls to Bakers Creek. In 2006, surface water was sampled from Bakers Creek, directly east o f the Daikin America facility and PFOS and PFOA were both detected at this location at a concentration of 27,700 ng/L. In 2004, PFOA was detected in groundwater at the Toray Fluorofibers facility at a concentration o f 470 ng/L. 1203477 000 0201 1112 KW08 v ii November8, 2012 More research is needed to evaluate the significance of current and/or historical discharges from these and other sites and facilities that are discussed in this report. In June 2012, Exponent sampled surface water and, where available, sediments in the Tennessee River and its tributaries within the sampling areas listed below. These areas were selected to evaluate potential additional sources o f PFCs and/or to update/supplement sampling previously conducted by others. The PFOS concentrations ranged from 2.7 to 153 ng/L and PFOA ranged from 1.8 to 101 ng/L in surface water. For each area, the approximate river mile, range of PFOS and PFOA concentrations in surface water in June 2012, and potential sources are described below. The concentrations for PFOS and PFOA are also shown for each area in Figure ES-1. Average concentrations for locations with duplicate samples and locations with shallow and deep samples are shown on Figure ES-1. 180-, 160- J 140- O) S 120- O 100 1 80- c n PFOS PFOA HmflMh f t i h <<0DlQZ_ -OQ 5 5 hc- 3 S0) D o 5 Sampling Area Figure ES-1.

Potential PFC sources are releases from agricultural areas where Decatur Utilities sludge had been applied and the City of Moulton WWTP that received leachate from the BFI Morris Farms Landfill where sludge from Decatur Utilities and others has been disposed. International Paper Plant area, River Mile 283, PFOS ranged from 38.4 to 45.9 ng/L and PFOA ranged from 24.9 to 27.1 ng/L. Potential PFC sources are releases from an agricultural area where Decatur Utilities sludge had been applied and discharges from International Paper. Browns Ferry Nuclear Power Plant area, River Mile 294, PFOS ranged from 10 to 32.4 ng/L and PFOA ranged from 6.5 to 17 ng/L. Potential PFC sources are erosion of surface soils and/or groundwater migration to the Tennessee River that may have been impacted with PFC-containing aqueous film-forming foam (AFFF). Mallard Creek area, River Mile 294, PFOS ranged from 35 to 36.7 ng/L and PFOA ranged from 20.1 to 23.4 ng/L. Potential PFC sources are releases from an agricultural area where Decatur Utilities sludge had been applied, BFI Morris Farms Landfill where sludge from Decatur Utilities and others was disposed, and Bert Jeffries Landfill that may have accepted PFC-containing wastes. Fox Creek area, River Mile 296, PFOS ranged from 53.1 to 153 ng/L and PFOA ranged from 31.3 to 101 ng/L. Potential PFC sources are releases from the Morgan County Regional Landfill where sludge from Decatur Utilities and others had been disposed and releases from the nearby Mallard-Fox Creek Industrial Park (Industrial Park). The Industrial Park area located along the shoreline o f the Tennessee River, River Mile 298, PFOS ranged from 75.9 to 101 ng/L and PFOA ranged from 34.1 to 50.6 ng/L. Potential PFC sources are releases from the Industrial Park and sediments dredged from the river and placed along the shoreline that may have contained PFCs. 1203477 000 0201 1112 KW08 IX November 8, 2012 Bakers Creek area, River Mile 301, was not sampled in June 2012. Potential PFC sources, aside from the 3M Decatur facility, are releases from an agricultural area where Decatur Utilities sludge had been applied, Daikin America/MDA Manufacturing, Toray Fluorofibers, Ascend Performance Materials (APM), and BPA. APM area, River Mile 302, PFOS ranged from 5.31 to 6.29 ng/L and PFOA ranged from 3.68 to 5.25 ng/L. A potential PFC source is discharges from APM. Betty Rye Branch area, River Mile 303, PFOS ranged from 20.8 to 53.4 ng/L and PFOA ranged from 9.14 to 19.2 ng/L. Potential PFC sources are releases from current and historical industrial and commercial facilities including APM and Nichols Aluminum. Dry Branch area, River Mile 303, PFOS ranged from 19.3 to 22.3 ng/L and PFOA ranged from 9.58 to 9.8 ng/L. Potential PFC sources are releases from current and historical paper, fabric, box, and furniture manufacturers. Pryor Field Regional Airport area1, River Mile 303, PFOS ranged from 2.71 to 3.75 ng/L and PFOA ranged from 2.25 to 2.47 ng/L. Potential PFC sources are releases from an agricultural area where Decatur Utilities sludge had been applied and the potential use of PFC-containing AFFF at the airport. Decatur Utilities WWTP area, River Mile 303.5, PFOS ranged from 2.76 to 4.31 ng/L and PFOA ranged from 1.8 to 3.08 ng/L. The source o f PFCs in this area is the discharge o f PFC-containing effluent from the WWTP. PFC contributors to the WWTP have included 3M, Daikin America/MDA Manufacturing, Toray Fluorofibers, and the Morgan County Regional Landfill. 1 Subsequent to sampling, a surface water discharge point was located downriver o f the sampling locations. Surface water samples should be collected downriver o f these sampling locations in the fall 2012 sampling program. 1203477 000 0201 1112 KW08 X November 8, 2012 Wolverine Tube area, River Mile 307, PFOS ranged from 6.83 to 9.15 ng/L and PFOA ranged from 5.22 to 5.89 ng/L. Potential PFC sources are releases from agricultural areas where Decatur Utilities sludge had been applied and discharges from historical facilities that may have used PFCs (Wolverine Tube and HCI Coatings). The results of the surface water and sediment sampling demonstrated that there are other sources contributing PFCs to the river besides 3M. As a result o f the potential source research and recent sampling, a comprehensive fish sampling program to determine the levels of PFCs in fish tissue as a result o f these multiple potential sources to the river is recommended. Specifically, largemouth bass and channel catfish should be sampled in most of the areas that were sampled for surface water in June 2012, as well as in the Bakers Creek area in the vicinity of the 3M Decatur facility and other PFC sources. Surface water samples would be collected concurrently to provide information on the PFCs that the fish are currently exposed to. The water samples will provide a more robust data set for assessing chemical fingerprinting opportunities. Surface water sampling should also be performed along at least eight cross-river transects to provide current information on PFC levels throughout the Wheeler Reservoir. 1203477 000 0201 1112 KW08 XI 1 Site Background November 8, 2012 The 3M Decatur facility covers approximately 900 acres and is located at 1101 State Docks Road in Decatur, Alabama, along the south shoreline of the Wheeler Reservoir o f the Tennessee River at approximate River Mile 300.5. 3M began operations at the Decatur facility in 1961 with the construction of a chemical manufacturing plant to produce perfluorinated chemicals (PFCs) and other products. In 1962, the facility was expanded to include a film manufacturing plant. Between 1961 and 1962, 3M also constructed an onsite wastewater treatment plant (WWTP) with discharge to the Tennessee River. Dyneon, located on the southern portion o f the 3M Decatur facility, began operations in 1996. Dyneon manufactures vinylidene fluoride and polyvinylidene fluoride (PVDF). Process wastewater generated at Dyneon is managed at 3M 's WWTP prior to discharge to the Tennessee River. Several other manufacturing facilities have been constructed upriver and downriver of the 3M Decatur facility along the approximate 10-mile industrial area located along the south shore of the Tennessee River. Some o f these facilities, either currently or in the past, manufactured PFCs, used them as part of their manufacturing process, and/or used PFC-containing aqueous film-forming foam (AFFF) for fighting fires, responding to other emergencies, and/or conducting emergency response training. In June 2012, Exponent conducted research along with surface water and sediment sampling to identify potential sources of PFCs to the Tennessee River and its tributaries upriver and downriver o f the 3M Decatur facility. The results o f the research and sampling activities are discussed in the following sections. 1203477 000 0201 1112KW08 1 2 Methodology November 8, 2012 This section describes the methodology used by Exponent to evaluate, generate, and analyze PFC data in the project area. As described below, Exponent researched existing information and completed sampling and analysis in June 2012. 2.1 Research Exponent researched historical sampling data and the history of potential sources to develop an understanding of conditions in the project area. This research is described in the sections below. 2.1.1 Historical Sampling Data Surface water and sediment samples have been collected and analyzed in the project area by several researchers. Exponent reviewed these historic sampling data; these data are summarized in Appendix A. Figures showing historical sampling locations are also provided in Appendix A. Pertinent results are discussed in Section 3. 2.1.2 Potential Source Evaluation Research was conducted concurrently with June 2012 sampling activities to identify potential sources o f PFCs to the Tennessee River and its tributaries. This research included identifying facilities where PFCs may have been used or manufactured and where AFFFs may have been used. Surface water drainage from these facilities was also reviewed to evaluate possible pathways to the Tennessee River. The following research activities were conducted: Obtained an Environmental Data Resources report that lists industries in the City of Decatur with environmental records Conducted an area reconnaissance near/along the Tennessee River 1203477 000 0201 1112 KW08 2 November 8, 2012 Conducted a reconnaissance o f upland areas, where groundwater and surface water may ultimately discharge to the Tennessee River Reviewed historical maps Reviewed historical reverse street directories from 1952 to 2004 Reviewed the yellow pages o f phone books from 1952 to 2004 Reviewed pertinent newspaper articles from the 1970s to the present Reviewed available U.S. Environmental Protection Agency (EPA) Section 308 Clean Water Act information requests regarding the manufacture and use o f PFCs at facilities in the Decatur area and whether or not those PFCs were discharged to the Decatur Utilities WWTP Contacted the local fire department to obtain information about historic fires where AFFF may have been used. Potential sources o f PFCs to the Tennessee River and its tributaries based on this review are discussed in Section 3. 2.2 June 2012 Sampling Activities In June 2012, Exponent collected samples o f surface water and sediment (where possible) from 12 areas in the Tennessee River and its tributaries upriver and downriver o f the 3M Decatur facility (Figure 1). The areas were selected to evaluate potential additional sources o f PFCs and/or to update/supplement sampling previously conducted by others. Sampling was not conducted within Bakers Creek in June 2012 because the concentrations o f PFCs from several potential sources in this tributary are generally known and 3M 's and Daikin's National Pollutant Discharge Elimination System (NPDES) discharges to Bakers Creek are monitored for PFCs on a regular basis. The sampling areas were proximate to: 1203477 000 0201 1112 KW08 3 November 8, 2012 Mouth of Big Nance Creek Shoreline of International Paper Plant Shoreline o f Browns Ferry Nuclear Power Plant and near the outfall diffuser Mouth of and upstream in Mallard Creek Mouth of and upstream in Fox Creek Shoreline of the Mallard-Fox Creek Industrial Park (Industrial Park) Shoreline of Ascend Performance Materials (APM) Mouth of and upstream in Betty Rye Branch Mouth of and upstream in Dry Branch Shoreline west-southwest o f Pryor Field Regional Airport Area o f the Decatur Utilities WWTP outfall diffuser Shoreline of Wolverine Tube. These sampling areas are shown on Figure 1 and Figures B-2 through B -l 1 in Appendix B. The collected surface water and sediment samples were analyzed by AXYS Analytical Services (AXYS). Detailed laboratory reports can be found in Appendix B. The following PFCs were analyzed by AXYS as part o f their standard analytical suite: Perfluorobutanoic acid (PFBA) Perfluoropentanoic acid (PFPeA) Perfluorohexanoic acid (PFHxA) Perfluoroheptanoic acid (PFHpA) Perfluorooctanoic acid (PFOA) 1203477 000 0201 1112 KW08 4 November 8, 2012 Perfluorononanoic acid (PFNA) Perfluorodecanoic acid (PFDA) Perfluoroundecanoic acid (PFUnA) Perfluorododecanoic acid (PFDoA) Perfluorobutane sulfonate (PFBS) Perfluorohexane sulfonate (PFHxS) Perfluorooctane sulfonate (PFOS) Perfluorooctane sulfonamide (PFOSA). Sampling areas, surface water sampling methodology, sediment sampling methodology, quality assurance and quality control (QA/QC) samples, decontamination procedures, and sampling results are discussed in Appendix B. Pertinent results are discussed in Section 3. 1203477 000 0201 1112 KW08 5 3 Results and Discussion November 8, 2012 Results o f the June 2012 sampling activities and potential source review are presented in the sections below. Unless otherwise noted, the results discussed below are for individual samples or the average measurements taken at one location during one event (e.g., the sample and a field or laboratory duplicate). These results are presented without distinguishing whether they are "individual" or "average." The discussions in this section also describe averages across multiple sampling locations, which are distinguished as "average." 3.1 June 2012 Sampling Activities In June 2012, surface water and sediment samples were collected from the Tennessee River and its tributaries to evaluate potential sources of PFCs and/or to update/supplement sampling previously conducted by others. Sampling activities were completed within the 12 sampling areas discussed previously located between River Mile 274 (just downriver of the Wheeler Dam) and River Mile 308 (just downriver o f Flint Creek) (Figure 1). A summary o f sampling activities and results is provided in the following sections and in Appendix B. 3.1.1 Surface Water Surface water samples were collected from each sampling area and analyzed for the 13 PFCs noted in Section 2.2., total dissolved solids, and total suspended solids. Samples were also measured in the field for temperature, conductivity, pH, dissolved oxygen, and turbidity. PFOA and PFOS were detected in all collected samples. Surface water samples collected from the Big Nance Creek, International Paper Plant, Browns Ferry Nuclear Power Plant, and Mallard Creek sampling areas had an average PFOS concentration of 33.04 nanograms per liter (ng/L) and an average PFOA concentration o f 20.81 ng/L. 1203477 000 0201 1112 KW08 6 November8, 2012 The highest concentrations of PFOS and PFOA were detected in samples collected in Fox Creek and near the Industrial Park. These areas had an average PFOS concentration o f 92.92 ng/L and an average PFOA concentration o f 49.28 ng/L. Sampling areas located upriver of Bakers Creek had an average PFOS concentration of 4.73 ng/L and an average PFOA concentration o f 3.37 ng/L, with the exception o f Betty Rye Branch and Dry Branch. These areas had an average PFOS concentration o f 28.95 ng/L and an average PFOA concentration o f 11.93 ng/L, with the highest PFOA and PFOS concentrations detected in the upstream sample collected in Betty Rye Branch. PFBS, PFHxS, and PFOSA were detected at average concentrations of 24.4 ng/L, 8 ng/L and 3.3 ng/L, respectively, in samples collected downriver o f Bakers Creek. The highest concentrations were detected in samples collected in Fox Creek and near the Industrial Park. Samples collected upriver of Bakers Creek had average concentrations o f 3.2 ng/L, 4.8 ng/L and 1.4 ng/L o f PFBS, PFHxS and PFOSA, respectively. PFBA and PFHxA were detected in samples collected downriver of Bakers Creek at average concentrations o f 25.7 and 29.6 ng/L, respectively, with the highest concentrations detected in a sample collected in Fox Creek. PFBA and PFHxA were detected in samples collected upriver of Bakers Creek at average concentrations of 9.7 ng/L and 3.2 ng/L, respectively. PFPeA and PFHpA were detected at levels less than 11 ng/L with the exception o f Fox Creek and near the Industrial Park. The average PFPeA and PFHpA concentrations in Fox Creek and near the Industrial Park were 14.5 ng/L and 22.7 ng/L, respectively, with the highest concentrations detected in a sample collected in Fox Creek. PFNA was not detected or was detected close to the reporting limit (maximum detection of 1.04 ng/L near the Industrial Park). PFDA, PFUnA, and PFDoA were not detected in any samples. A complete summary o f surface water sample results and water quality parameters is presented in Appendix B. 1203477 000 0201 1112 KW08 7 November 8, 2012 3.1.2 Sediment Sediment samples were collected in all sampling areas with the exception o f two areas, International Paper Plant and Browns Ferry Nuclear Power Plant. The river bottom at these areas consisted mainly o f shells and gravel. Collected sediment samples were analyzed for the 13 PFCs noted in Section 2.2, total organic carbon, total solids, and particle size. Sediment samples collected from the Big Nance Creek and Mallard Creek sampling areas had an average PFOS concentration o f 3.51 nanograms per gram (ng/g) and an average PFOA concentration o f 0.2 ng/g. The highest concentrations o f PFOS were detected in samples collected in Fox Creek and near the Industrial Park. These areas had an average PFOS concentration o f 8.21 ng/g and an average PFOA concentration of 0.5 ng/g. Sampling areas located upriver o f Bakers Creek had an average PFOS concentration o f 1.1 ng/g, with the exception of the upstream sample collected in Dry Branch. PFOS was detected in this sample at 11.9 ng/g. PFOA was either not detected or was detected at sub-parts per billion levels (highest PFOA concentration o f 0.23 ng/g) in these sampling areas. PFBS and PFHxS were not detected in any samples, with the exception o f samples collected from Fox Creek and near the Industrial Park. PFBS was detected near the Industrial Park at 0.228 ng/g and PFHxS was detected in Fox Creek at 0.197 ng/g. The concentrations o f PFOSA in collected samples ranged from non-detect to 1.84 ng/g, with the highest concentration detected in a sample collected near the Industrial Park. PFBA, PFpeA, and PFNA were not detected in any collected samples. PFHxA, PFHpA, PFDA, PFUnA, and PFDoA were not detected or detected at low levels. The maximum concentrations of PFHxA, PFHpA, PFDA, PFUnA, and PFDoA were 0.27 ng/g, 0.179 ng/g, 0.124 ng/g, 0.106 ng/g, and 0.234 ng/g, respectively. These maximum 1203477 000 0201 1112 KW08 8 November8, 2012 concentrations were detected in samples collected at Big Nance Creek, Fox Creek, Mallard Creek, and Pryor Field Regional Airport. A complete summary o f sediment sample results is presented in Appendix B. 3.2 Potential Source Evaluation Based on the research conducted, several facilities were identified as potential sources of PFCs to the Tennessee River. These potential sources are discussed below by areas that they may influence within the Tennessee River. These areas were sampled in June 2012 (Appendix B). The selection was based on 1) the general proximity to the areas sampled and 2) the potential surface water drainage pathways to those sections of the river sampled. These areas include, from downriver to upriver (generally): Big Nance Creek International Paper Plant Browns Ferry Nuclear Power Plant Mallard Creek Fox Creek Industrial Park APM Betty Rye Branch Dry Branch Pryor Field Regional Airport Decatur Utilities WWTP Wolverine Tube. 1203477 000 0201 1112 KW08 9 November 8, 2012 Although Bakers Creek was not sampled in June 2012, potential sources o f PFCs to Bakers Creek (other than 3M) identified during research activities are also discussed below. The locations o f the potential sources o f PFCs are shown on Figures 2 and 3. 3.2.1 Big Nance Creek Area Big Nance Creek discharges to the Tennessee River at approximate River Mile 274, downriver of the Wheeler Dam. Upstream creeks that flow into Big Nance Creek include Muddy Fork and Crow Branch (Figure 2). Potential sources o f PFCs to Big Nance Creek include the land-application of sewage sludge (biosolids) and discharges from the City o f Moulton WWTP. From approximately 1996 to 2008, biosolids from the Decatur Utilities WWTP were land-applied to approximately 5,000 acres o f privately-owned agricultural land in Lawrence, Morgan, and Limestone Counties (U.S. EPA 2011). In September 2008 and February 2009, EPA collected surface soil and surface water samples from some o f these agricultural lands to determine if the biosolids generated at the Decatur Utilities WWTP were contaminated with PFCs and if the land application o f these biosolids resulted in potential releases o f PFCs to the environment. Two o f the agricultural areas that received sludge applications are located downgradient of the City o f Moulton WWTP and potentially drain to Crow Branch and Muddy Fork. EPA collected surface soil and surface water samples from the agricultural area that potentially drains to Crow Branch. PFOS was detected in surface soil at 715 ng/g and PFOA was detected in surface soil at 818 ng/g (U.S. EPA 2009a). PFOA was detected in surface water at 33.7 ng/L and PFOS was not detected (U.S. EPA 2009b). Samples were not collected from the agricultural area whose run-off potentially flows to Muddy Fork. PFC-containing surface water from these agricultural areas may have discharged to Crow Branch and Muddy Fork, which discharge into Big Nance Creek and ultimately to the Tennessee River. After November 2008, biosolids from the Decatur Utilities WWTP were no longer land-applied and were sent instead to area landfills for disposal, including the BFI Morris Farms Landfill. Leachate generated at this landfill was sent to the City o f Moulton WWTP for treatment. Wastewater discharges from the City o f Moulton WWTP to Crow Branch, which ultimately 1203477 000 0201 1112 KW08 10 November8, 2012 discharges to Big Nance Creek, were found to contain PFOS and PFOA. In 2011, PFOS ranged from 619 to 5,440 ng/L and PFOA ranged from 1,240 to 9,860 ng/L in wastewater discharged to Crow Branch (U.S. EPA 2012b). PFOS was detected at 92.3 ng/L and PFOA was detected at 295 ng/L (Hansen et al. 2002) in a surface water sample collected in November 2000 at approximate River Mile 273 (near the mouth of Big Nance Creek). These detections were close to the average PFOS and PFOA concentrations detected in samples collected downriver o f Fox Creek in November 2000 (average PFOS concentration o f 114 ng/L and average PFOA concentration o f 389 ng/L). Surface water samples collected from the mouth o f Big Nance Creek in June 2012 (Figure 1) contained 18.3 and 45.7 ng/L o f PFOS and 15.3 and 30.2 ng/L o f PFOA (Appendix B). 3.2.2 International Paper Plant Area International Paper Plant is a large paper manufacturing facility located along the south shoreline of the Tennessee River at approximate River Mile 283. Potential sources o f PFCs in the vicinity o f this paper plant include the land-application o f biosolids and discharges from this plant to the Tennessee River. As stated above, biosolids from the Decatur Utilities WWTP were land-applied to privately-owned agricultural land until November 2008, when the land-applied biosolids were found to contain PFCs. One o f the agricultural areas that received sludge applications is located near Spring Creek that discharges just upriver o f the International Paper Plant. This agricultural area was not sampled by EPA in September 2008 or February 2009. PFC-containing run-off from this agricultural area may have discharged to Spring Creek which discharges into the Tennessee River, just upriver of the International Paper Plant. The International Paper Plant may be a source of PFCs due to the potential past and/or current use of PFC-containing coatings during paper manufacturing. Paper coating has been a common use of PFCs to water-proof and grease-proof paper used for a variety of uses such as food 1203477 000 0201 1112 KW08 11 November 8, 2012 wrapping and pet food bags (EFSA 2012; Trier et al. 2011; Kissa 2001; Walker 2005; Tittlemier et al. 2007). In 2009, this facility reported an average production o f 23.7 million pounds o f coated paper per month (International Paper 2009). This facility also has a NPDES permit for discharges to the Tennessee River. The main constituents monitored as part of this permit are chlorophenolic compounds. Monitoring for PFCs has not been required in this NPDES permit. Surface water samples were collected in November 2000 and July 2005 at approximate River Mile 283 and in June 2012 along the shoreline of International Paper Plant. In November 2000, PFOS was detected at 106 ng/L and PFOA was detected at 355 ng/L (Hansen et al. 2002). In July 2005, PFOS was detected at 61.6 ng/L and PFOA was detected at 38.9 ng/L (Weston 2008a,b). Surface water samples collected in June 2012 (Figure 1) contained 38.4 to 45.9 ng/L o f PFOS and 24.9 to 27.1 ng/L o f PFOA (Appendix B). These data and the presence of PFC-generating activities near this location indicate that there are potential local sources. 3.2.3 Browns Ferry Nuclear Power Plant Area The Browns Ferry Nuclear Power Plant is located along the north shore o f the Tennessee River at approximate River Mile 294. Shortly after this plant began operations in January 1975, a fire occurred in the cable spreading room and Unit 1 reactor building. Another fire occurred in 1986 that destroyed a cooling tower. Potential sources of PFCs at this plant include the potential use o f PFC-containing AFFFs during these fires that may have contaminated groundwater and surface soils which periodically migrated/eroded into the Tennessee River. Surface water samples were collected in November 2000 and July 2005 at approximate River Miles 293 and 295 and in June 2012 along the shoreline o f this facility. In November 2000, PFOS was detected at 74.8 and 96.4 ng/L and PFOA was detected at 140 and 203 ng/L 1203477 000 0201 1112 KW08 12 November8, 2012 (Hansen et al. 2002). In July 2005, PFOS was detected at 74.2 ng/L and PFOA was detected at 67.3 ng/L (Weston 2008a,b). Surface water samples collected in June 2012 (Figure 1) contained 10 to 32.4 ng/L o f PFOS and 6.5 to 17 ng/L o f PFOA (Appendix B). These data indicate a potential trend in decreasing PFOS and PFOA concentrations from 2000/2005 to 2012 in this area. It is unclear if there are local or upriver sources influencing these results. 3.2.4 Mallard Creek Area Mallard Creek is a small tributary that drains into the Tennessee River at approximate River Mile 294. Potential sources of PFCs to Mallard Creek include the land-application o f biosolids and discharges from BFI Morris Farms Landfill and Bert Jefferies Landfill. As stated above, biosolids from the Decatur Utilities WWTP were land-applied to privately-owned agricultural land until November 2008, when the land-applied biosolids were found to contain PFCs. One o f the agricultural areas that received sludge applications is located upgradient of Mallard Creek. In September 2008, EPA collected surface soil samples from this agricultural area. PFOS was detected in surface soil at 1,296 and 1,409 ng/g and PFOA was detected in surface soil at 1,895 and 2,531 ng/g (U.S. EPA 2009a). Based on a review o f topographic maps, surface water from this agricultural area likely flows toward Mallard Creek and PFC-containing run-off from this agricultural area may discharge to Mallard Creek, which discharges into the Tennessee River. Beginning in approximately 2009, biosolids from the Decatur Utilities WWTP were disposed of at BFI Morris Farms Landfill. This landfill also accepted sludge from the treatment o f process wastewater at 3M, Daikin America, and others. Leachate generated at this landfill was found to contain PFOS and PFOA. PFOA and PFOS were reportedly detected in landfill leachate at 91,600 ng/L and greater than 55,000 ng/L, respectively (Decatur Daily 2009a). In March 2011, groundwater was sampled from wells located upgradient and along the perimeter o f the landfill. PFOS and PFOA were detected in shallow groundwater in an upgradient well at 242 ng/L and 1203477 000 0201 1112 KW08 13 November 8, 2012 325 ng/L, respectively (Weston 2011; 3M 2011). PFOS and PFOA were detected in a shallow downgradient well at 22,500 ng/L and 24,300 ng/L, respectively (Weston 2011; 3M 2011). Based on a review of topographic and hydrogeological maps, surface water and groundwater from this landfill likely flow toward Mallard Creek and potential PFC-containing run-off and groundwater from this landfill may discharge to Mallard Creek, which discharges into the Tennessee River. The Bert Jefferies Landfill is a former waste disposal site previously operated by Bert Jefferies Construction Company located approximately 0.5 miles south o f the mouth o f Mallard Creek. This facility recycled drums and received several types o f wastes (e.g., scrap rolls of plastic film, pallets, and drums o f solidified resins and plastics) from 1977 to 1982. This landfill reportedly had a contract with 3M to dispose o f non-chemical wastes (film, paper, cardboard, and drums o f solid plastic) during the 1970s (Times Daily 1991); although it may have also accepted PFC-containing wastes from other companies as well. A hydrogeologic investigation at this site identified a volatile organic compound groundwater plume migrating toward Mallard Creek. In 2011, 3M acquired the former Bert Jeffries site. Groundwater, surface water, and sediment were sampled on the site in 2012 and analyzed for PFOA, PFOS, PFHS, and/or PFBS (Weston 2012c; 3M 2012a,b,c). PFOS and PFOA were detected in groundwater at 22,500 ng/L and 8,260 ng/L, respectively, in a well located downgradient of the suspected waste disposal area. PFOA and PFOS ranged from undetectable to 112 ng/L and 30.2 to 303 ng/L, respectively, in surface water collected from a drainage feature located along the east side o f the site. PFOA and PFOS in sediment in the same drainage ditch ranged from 0.629 to 2.39 ng/g and 3.95 to 23.8 ng/g, respectively. This east drainage flows in a northerly direction, ultimately discharging into Mallard Creek. Surface water samples were collected in December 2004, December 2006, and June 2012 from Mallard Creek. In December 2004, PFOS was detected at 275 ng/L and PFOA was detected at 212 ng/L at the mouth o f Mallard Creek (Weston 2008a,b). In December 2006, samples were collected again at the mouth of Mallard Creek and PFOS was detected at 48.3 ng/L and PFOA was detected at 51.1 ng/L (Weston 2008a,b). 1203477 000 0201 1112 KW08 14 November 8, 2012 Surface water samples were collected from Mallard Creek in June 2012 (Figure 1) upstream and at the mouth. PFOS was detected at 35 and 36.7 ng/L and PFOA was detected at 20.1 and 23.4 ng/L, with the higher concentrations in the sample collected at the mouth o f Mallard Creek (Appendix B). 3.2.5 Fox Creek and Industrial Park Areas Fox Creek is a small tributary that drains into the Tennessee River at approximate River Mile 296. Potential sources of PFCs to Fox Creek include operations conducted in the nearby Industrial Park and run-off from the Morgan County Regional Landfill. The Industrial Park was completed in 1991 and is located along the south bank o f the Tennessee River and east of Fox Creek. Prior to completion o f the Industrial Park in 1991, approximately 133,000 cubic yards o f sediment from the Tennessee River was dredged to open a channel for barge traffic. The dredged material was placed in a 99-acre dredge disposal area on the bank of the river. PFC-containing sediments may have been dredged from the river and placed along the shoreline. Current companies located within this Industrial Park that may be potential sources o f PFCs to the Tennessee River include the following: Neo Industries-- Conducts hard chromium electroplating which may use a PFOS-containing mist suppressor (currently and/or historically) during plating operations. Surface water drainage from this facility appears to flow to the northwest, toward Fox Creek. Hexcel-- Currently produces a precursor material used in carbon fiber and may have historically used PFC-treatment on textiles during textile manufacturing. Hexcel is located on the south shore of the Tennessee River, at approximate River Mile 298, and has a NPDES permit for discharges to the Tennessee River; however, monitoring for PFCs is not required at this time. 1203477 000 0201 1112 KW08 15 November 8, 2012 Nucor Steel (formerly Tricor Steel)-- Produces hot-rolled, pickled, and cold-rolled sheet metal. PFOS can be present in metal sludge from electroplating. Some steel manufacturers are known to recycle electroplating metal sludge and, as a result, PFOS can enter the steel manufacturing waste stream. Trico Steel, which began producing steel in 1997, applied for a NPDES permit for the discharge o f approximately 600 gallons per minute o f treated wastewater to the Tennessee River and an unnamed tributary o f the Tennessee River. This facility may have also used PFC-containing AFFF during a fire in March 1998 o f direct-reduced iron, a coke material used in steel processing (Decatur Daily 1998). Surface water drainage from this facility appears to flow to the northwest, toward Fox Creek. This facility has a NPDES permit for discharges to the Tennessee River and a tributary o f the Tennessee River; however, monitoring for PFCs is not required at this time. The Morgan County Regional Landfill is located approximately 3.5 miles south o f the mouth o f Fox Creek. Biosolids from the Decatur Utilities WWTP were disposed o f at this landfill and leachate generated at this landfill was found to contain PFOS and PFOA (Decatur Daily 2009b). This landfill also accepted sludge from the treatment of process wastewater at 3M and possibly other companies. In June 2005, leachate from this landfill was analyzed and contained a PFOS concentration o f 43,200 ng/L and a PFOA concentration of 43,100 ng/L (3M 2008). The landfill leachate was tested again in April 2006 and contained a PFOS concentration o f 27,400 ng/L and a PFOA concentration of 48,700 ng/L. In approximately April 2011, a treatment system was installed to treat PFCs in the landfill leachate. Following treatment, the concentration o f PFCs in leachate was reportedly reduced (Decatur Daily 2011). In November 2010, groundwater was sampled from wells located upgradient and downgradient o f the Morgan County Regional Landfill (Weston 2010; 3M 2010). PFOS and PFOA in the downgradient wells ranged from 30.6 to 14,800 ng/L and undetectable at the reporting limit of 25 ng/L to 7,130 ng/L, respectively. In the upgradient well, PFOS was not detected above the reporting limit o f 25 ng/L and PFOA ranged from undetectable at the reporting limit o f 25 ng/L to 148 ng/L (depending on the well depth at the one location sampled). The upgradient well 1203477 000 0201 1112 KW08 16 November 8, 2012 was sampled again in March 2012 and PFOA ranged from undetectable at the reporting limit of 24 ng/L to 85 ng/L (Weston 2012d). Surface water and groundwater from this landfill appear to flow to the northwest, toward Fox Creek. Leachate generated at this circa 1980 landfill may not be completely captured and could result in releases to Fox Creek. Surface water samples were collected in June 2000, December 2004, and December 2006 from the mouth of Fox Creek and in July 2005 along the shoreline of the Industrial Park. Additional samples were collected from Fox Creek and along the shoreline o f the Industrial Park in June 2012. In June 2000, PFOS ranged from 486.5 to 585.5 ng/L and PFOA ranged from 1,985 to 3,460 ng/L (Entrix 2001). In December 2004, PFOS was detected at 192 ng/L and PFOA was detected at 190 ng/L (Weston 2008a,b). In December 2006, PFOS was detected at 63.8 ng/L and PFOA was detected at 76.4 ng/L (Weston 2008a,b). A surface water sample was also collected along the shoreline of the Industrial Park in July 2005. PFOS and PFOA at this location were detected at 123 ng/L and 137 ng/L, respectively (Weston 2008a,b). Surface water samples collected from Fox Creek, at the mouth and upstream in June 2012 (Figure 1), contained 53.1 and 153 ng/L o f PFOS and 31.3 and 101 ng/L o f PFOA, with the highest concentrations in the upstream sample. Surface water samples collected in June 2012 along the shoreline o f the Industrial Park area contained 75.9 to 101 ng/L o f PFOS and 34.1 to 50.6 ng/L o f PFOA (Appendix B). There appears to be a decreasing trend over time in PFOS concentrations in water samples in this area. However, the recent data still show levels above background concentrations. 3.2.6 Bakers Creek Area Bakers Creek is located to the east o f the 3M Decatur facility and potential sources o f PFCs to this creek, aside from the 3M Decatur facility, include the land-application of biosolids and discharges from current and historical companies located in the Bakers Creek drainage area. 1203477 000 0201 1112 KW08 17 November 8, 2012 As stated above, biosolids from the Decatur Utilities WWTP were land-applied to privately-owned agricultural land until November 2008, when the land-applied biosolids were found to contain PFCs. One o f the agricultural areas that received sludge applications is located near the Bakers Creek tributary. In February 2009, EPA collected surface water samples from this agricultural area. PFOA concentrations in surface water ranged from non-detect to 30.1 ng/L. PFOS concentrations in surface water ranged from 21.1 to 31.7 ng/L (U.S. EPA 2009b). Surface water drainage in the area o f this agricultural area appears to flow to the north, toward/with Bakers Creek, which discharges into the Tennessee River. PFC-containing surface water from this agricultural area may have discharged to Bakers Creek and ultimately to the Tennessee River. Current companies, other than 3M, that are potential sources o f PFCs to Bakers Creek include: Daikin America/MDA Manufacturing, located adjacent to the 3M Decatur facility, began operations in approximately 1993. Daikin America stores/ handles perfluorohexane and produces UnidyneTM, a fluorinated water and oil repellant. PFC-containing AFFFs may have also been used during fires in May 1999, January 2008, and March 2008. PFOA has been analyzed as part o f Daikin America's NPDES permit beginning in approximately December 2008. Between December 2008 and September 2012, PFOA was detected between 4,540 and 307,000 ng/L in effluent discharged from three outfalls to Bakers Creek (U.S. EPA 2012a; ADEM 2012). Daikin America also has an outfall that discharges directly to the Tennessee River. This outfall is located approximately 2,900 feet north-northwest o f the mouth o f Bakers Creek. PFOA measured in discharge to this outfall ranged from 758 to 27,500 ng/L between December 2008 and September 2012 (U.S. EPA 2012a; ADEM 2012). Daikin America's NPDES permit was recently modified in May 2012 to include quarterly monitoring of PFOS and other PFCs. In September 2012, PFOS was detected between 27,000 and 60,000 ng/L in effluent discharged from three outfalls to Bakers Creek (ADEM 2012). PFOS was also detected 1203477 000 0201 1112 KW08 18 November 8, 2012 at 580 ng/L in effluent discharged directly to the Tennessee River (ADEM 2012). Toray Fluorofibers, located east o f the 3M Decatur facility, manufactures polytetrafluoroethylene (PTFE) fiber. PTFE was introduced by DuPont and given the name Teflon. Toray Fluorofibers purchased the business from DuPont and began production of PTFE at the Decatur facility in August 2004. PFOA has been essential for the synthesis and manufacture of PTFE. PFOA functions as a polymerization aid but is not structurally incorporated in the final product. Much of the manufacturing processes conducted at the facility are confidential; however, it is likely that Toray Fluorofibers is a source o f PFOA and other PFCs to the Tennessee River. Some wastes from Toray Fluorofibers were also disposed o f at Morgan County Regional Landfill, a landfill with known PFC-containing leachate. Sampling conducted at/around Toray Fluorofibers (actual locations not known) in December 2004 (Toray Fluorofibers 2011) detected the following: - 470 ng/L o f PFOA in a monitoring well - 6.5 ng/g o f PFOA in subsurface soil - 7.7 ng/g o f PFOA in surface soil. As mentioned in Section 3.2.11, PFOA was detected in wastewater discharged from the Toray Fluorofibers facility to the Decatur Utilities WWTP. Toray Fluorofibers has a current NPDES permit for the discharge of non-contact cooling water, cooling tower blowdown, and boiler blowdown to Bakers Creek; however, monitoring for PFCs is not required. As discussed in Section 3.2.7, APM, located to the east o f the 3M Decatur facility, may have used PFCs during their manufacturing processes. Discharges from these processes may have drained to the Tennessee River via several NPDES permitted storm water outfalls to Bakers Creek. 1203477 000 0201 1112 KW08 19 November 8, 2012 Biological Processors o f Alabama (BPA), located to the west of the 3M Decatur facility, was an industrial liquid waste treatment facility for several businesses2 that may have treated PFC-containing wastes. This facility operated from approximately 2004 to 2008, treated wastes onsite, disposed of certain treated wastes at landfills, and/or discharged the treated wastes to the Decatur Utilities WWTP. During its operation, BPA was cited for more than 100 illegal discharges to the Decatur Utilities WWTP. When BPA ceased operations in 2008, thousands of gallons o f waste liquid and sludge were left behind. In 2009, EPA directed the Alabama Department of Environmental Management (ADEM) to assess the site under the Comprehensive Environmental Response, Compensation, and Liability Act. Samples of liquid and sludge wastes were collected in May 2009 and analyzed for PFCs. Several PFCs were detected in the samples analyzed, including PFOA and PFOS. The maximum PFOA and PFOS concentrations detected in sludge samples were 110 ng/g and 360 ng/g, respectively. The maximum PFOA and PFOS concentrations detected in liquid samples were 2,400 ng/L and 76,000 ng/L, respectively. During site visits conducted by ADEM in 2009, a drainage ditch located on the BPA site was identified that flows north along the west side o f Finley Island Road, then southeast onto the 3M Decatur facility, then east along Highway 20, and finally northeast into Bakers Creek (Figure 3) (ADEM 2009). Based upon the observations made by ADEM, it appears that surface water run-off and/or groundwater seepage could be transported to 2 In 2001, a number o f companies that had allegedly contributed waste to the BPA site signed a settlement agreement for recovery o f past response costs for the BPA site. These companies included: Action Resources, Inc.; Armor Environmental Services, Inc.; Ashland Inc., on behalf o f itself and its customers (Alcoa, Inc.; Caterpillar Inc.; Fuji Copian Corporation; Hanil E-Hwa Interior Systems; Honda Manufacturing o f Alabama, LLC; Hyundai Motor Manufacturing Alabama, LLC; International Flavors & Fragrances; Leading Edge Aviation Mississippi, Inc.; Mercedes-Benz U.S. International, Inc.; Oak Technical, LLC; and Tower Automotive Products Company, Inc.); Cedar Ridge Landfill, Inc.; Cytec Industries, Inc.; Hyundai Motor Manufacturing Alabama, LLC; Maverick Tube LLC; NemakUSA; OmniChem L.L.C.; One Stop Environmental, LLC; Premier Industrial Services, LLC; Printpack Inc.; Quail Hollow Landfill, Inc.; Safety-Kleen Systems, Inc.; Spectrum Industrial Services, Inc.; and TK Aluminum North America Inc. (also referred to as "Teksid"). 1203477 000 0201 1112 KW08 20 November 8, 2012 Bakers Creek from the BPA site via this drainage pathway. However, the ditch crosses the 3M property in the former sludge incorporation area, where sludge was injected into the subsurface in several fields or zones. The drainage appears to cross the northern part o f Field 14, a "control" field where sludge was reportedly not injected, and then along the southern boundary o f Field 10, a field that reportedly received 4,158 metric tons o f sludge (Weston 2008a). Surface water sampling was conducted in this drainage in April 2006 (Weston 2008a,b). A surface water sample collected upgradient of BPA had a PFOA concentration of 29,000 ng/L and a PFOS concentration of 15,100 ng/L. A surface water sample collected downgradient o f BPA had a PFOA concentration of 128,000 ng/L and a PFOS concentration of 279,000 ng/L (Weston 2008a,b). Releases from BPA could have contributed to this elevated concentration; however, more focused sampling is needed to evaluate the relative contribution o f the BPA site compared to the former sludge application Field No. 10. Other companies located upstream along Bakers Creek that may have used PFCs include: Whittaker Coatings & Chemicals, a protective coatings manufacturer HCI Coatings, an industrial coatings manufacturer. PFC-containing run-off from these facilities may have discharged to Bakers Creek. Surface water samples were collected in Bakers Creek in December 2004, April 2006, December 2006, and April 2012. In December 2004, PFOS was detected at 3,420 ng/L and PFOA was detected at 1,707 ng/L (Weston 2008a,b). In April 2006, five samples were collected and PFOS ranged from 62.7 to 27,700 ng/L and PFOA ranged from 106 to 27,700 ng/L. In April 2006, the highest concentration o f PFOS and PFOA was detected in the sample collected east o f the Daikin America/MDA Manufacturing facility. In December 2006 and April 2012, additional surface water samples were collected at the mouth of Bakers Creek. In December 2006, PFOS 1203477 000 0201 1112 KW08 21 November 8, 2012 was detected at 53 ng/L and PFOA was undetectable at the reporting limit o f 25 ng/L (Weston 2008a,b). In April 2012, PFOS was detected at 691 ng/L (Weston 2012b). 3.2.7 Ascend Performance Materials Area APM (formerly Chemstrand, Monsanto, and then Solutia) is located along the south shore o f the Tennessee River at approximate River Mile 302 between Bakers Creek and Betty Rye Branch. Historically, this facility manufactured chemical fibers, polystyrene plastics, and chemicals for use by textile mills and furniture manufacturers. APM may have used PFCs during these manufacturing processes. Discharges from these processes may have drained to the Tennessee River via several NPDES permitted outfalls to Bakers Creek, Betty Rye Branch, and the Tennessee River. Surface water samples were collected in November 2000, April 2012, and June 2012 near the shoreline o f the APM facility. In November 2000, PFOS was detected at 39.4 ng/L and PFOA was not detected above the reporting limit o f 25 ng/L. In April 2012, PFOS was detected at a concentration o f 23.7 ng/L (Weston 2012b). In June 2012, PFOS was detected from 5.31 to 6.29 ng/L and PFOA was detected from 3.68 to 5.25 ng/L (Appendix B). 3.2.8 Betty Rye Branch Area Betty Rye Branch is a small tributary that drains into the Tennessee River at approximate River Mile 303. This area may be potentially impacted by discharges from industrial and commercial sources including: APM, as discussed above. Nichols Aluminum (formerly Decatur Aluminum Corporation), a producer of painted aluminum sheets used in the construction and automotive markets. Between 1996 and 2005, Nichols Aluminum used a wet chrome pretreatment step as part of the coating operation, a process that may have used PFCs. 1203477 000 0201 1112 KW08 22 November 8, 2012 PFC-containing AFFFs may have also been used at this facility during fires in 1994 and 1998. No historical sampling was previously conducted in this area. In June 2012, surface water samples were collected from Betty Rye Branch at the mouth and upstream (Figure 1). These samples contained 20.8 and 53.4 ng/L o f PFOS and 9.14 and 19.2 ng/L o f PFOA, with the highest concentrations in the upstream sample (Appendix B). 3.2.9 Dry Branch Area Dry Branch is a small tributary that drains into the Tennessee River at approximate River Mile 303. Several industrial and commercial companies and a major municipal WWTP (Decatur Utilities WWTP) are located along Dry Branch and may be potential historic and/or current sources of PFCs. The Decatur Utilities WWTP receives wastewater from residential and industrial sources, including local facilities that manufacture or use PFCs and may discharge PFC-containing wastewater to the WWTP. A detailed discussion of the Decatur Utilities WWTP is presented in Section 3.2.11. Companies located along Dry Branch may have used PFCs to enhance the water repellency and stain resistance of fabric, paper, fiber, or other materials during their manufacturing processes. Discharges from these processes may have impacted Dry Branch. The historic companies located along Dry Branch include: Champion Paper, listed in historical documents as a paper manufacturer, not a paper mill. Actual paper manufacturing processes conducted at this facility are not known. Clement Paper, listed in historical documents as a paper manufacturer, not a paper mill. Actual paper manufacturing processes conducted at this facility are not known. Browns Brothers, listed in historical documents as a paper manufacturer, not a paper mill. Actual paper manufacturing processes conducted at this facility are not known. 1203477 000 0201 1112 KW08 23 November 8, 2012 Cover Stitch, a textile manufacturer. Bilt-Rite Box Company, a box manufacturer. Lakeside Industries, a waterproof fabric manufacturer. Pinecraft, a furniture manufacturer. Riddle Furniture Manufacturing, a furniture manufacturer. Six surface water samples were collected from the mouth o f Dry Branch in June 2000. PFOS was detected from 33.05 to 65.5 ng/L and PFOA was detected from 14.45 to 31.35 ng/L (Entrix 2001). Surface water samples were collected from Dry Branch at the mouth and upstream in June 2012 (Figure 1). These samples contained 19.3 and 22.3 ng/L o f PFOS and 9.58 and 9.8 ng/L o f PFOA (Appendix B). 3.2.10 Pryor Field Regional Airport Area Pryor Field is a small regional airport located at approximate River Mile 305. Potential sources of PFCs in this sampling area are the land-application of biosolids and the potential use of PFC-containing AFFFs at Pryor Field Regional Airport. As stated above, biosolids from the Decatur Utilities WWTP were land-applied to privately-owned agricultural land until November 2008, when the land-applied biosolids were found to contain PFCs. One o f the agricultural areas that received sludge applications is located north o f Pryor Field Regional Airport near a tributary that discharges to the Tennessee River. In February 2009, EPA collected surface water samples from this agricultural area. PFOS was detected in surface water at 13.2 ng/L and PFOA was not detected (U.S. EPA 2009b). This agricultural area is located near Swan Creek which flows to the southwest eventually discharging into the Tennessee River just downriver o f the Pryor Field Regional Airport. PFC-containing run-off from this agricultural area may have discharged to Swan Creek and 1203477 000 0201 1112 KW08 24 November 8, 2012 ultimately into the Tennessee River. Surface water samples were collected in December 2004 and 2006 near the mouth o f Swan Creek and PFOS and PFOA were not detected above the detection limit of 25 ng/L (Weston 2008a,b). This sampling location was located downriver of the June 2012 Pryor Field Regional Airport sampling area. Surface water samples collected in the Pryor Field Regional Airport area in June 2012 (Figure 1) contained 2.71 to 3.75 ng/L o f PFOS and 2.25 to 2.47 ng/L o f PFOA (Appendix B). Information uncovered after the June 2012 sampling indicated that run-off from both Pryor Field Regional Airport and the agricultural area that received sludge applications discharge into the Tennessee River downriver o f the June 2012 sampling area in the vicinity of Swan Creek (Figure 2). Therefore, samples collected from this area in June 2012 are likely not representative o f surface water that may have been impacted by discharges from these potential sources. 3.2.11 Decatur Utilities WWTP Area The Decatur Utilities WWTP receives wastewater from residential and industrial sources, including local facilities that manufacture or use PFCs and may discharge PFC-containing wastewater to the WWTP. PFC-containing effluent was historically discharged from the Decatur Utilities WWTP to the Tennessee River between River Miles 303 and 304 at the outfall diffuser (Figure 3). Effluent from the WWTP sampled in May 2005 contained a PFOS concentration of 2,850 ng/L and a PFOA concentration o f 17,400 ng/L (3M 2008). Effluent from the WWTP was sampled again in April 2006 and contained a PFOS concentration of 571 ng/L and a PFOA concentration o f 7,080 ng/L. The 3M Decatur facility has never knowingly discharged any process wastewater to the Decatur Utilities WWTP. From 2001 through 2009, 3M discharged sanitary wastewater to the Decatur Utilities WWTP (3M 2008, 2009). Sanitary wastewater from 3M sampled in April 2006 contained a PFOS concentration o f 4,480 ng/L and a PFOA concentration of 4,630 ng/L (3M 2008). Samples collected in April 2009 contained a PFOS and PFOA concentration o f 2,560 ng/L and 3,650 ng/L, respectively (3M 2009). 1203477 000 0201 1112KW08 25 November 8, 2012 Other facilities that have known discharges o f PFC-containing wastewater to the Decatur Utilities WWTP include: Daikin America/MDA Manufacturing--Prior to 2009, Daikin America discharged process wastewater to the Decatur Utilities WWTP (Decatur Daily 2009d). PFOS was detected in these discharges; however, Daikin America claims that it has never used PFOS (Decatur Daily 2009c). Toray Fluoroflbers-- Wastewater discharged from Toray Fluorofibers to the Decatur Utilities WWTP was monitored for PFOA between April 2009 and March 2011. PFOA in wastewater ranged from a high o f 43,200 ng/L in September 2010 to a low o f 47 ng/L in January 2011 (Toray Fluorofibers 2011). Other facilities that may have discharged PFC-containing wastewater to the Decatur Utilities WWTP include: Nichols Aluminum-- Used a wet chrome pretreatment step as part o f the coating operation that may have used PFCs. BPA-- This was an industrial liquid waste treatment facility for several businesses that may have treated PFC-containing wastes. The wastes were treated onsite and disposed of at landfills or discharged to the Decatur Utilities WWTP. As discussed above, from approximately 1996 to 2008, biosolids from the Decatur Utilities WWTP were land-applied to approximately 5,000 acres o f privately-owned agricultural land in Lawrence, Morgan, and Limestone Counties. Biosolids from New York City were also land-applied to some agricultural areas in the Decatur area for more than 10 years (U.S. EPA 2009a). In September 2008, EPA collected samples o f biosolids from the Decatur Utilities WWTP and New York City, surface soil samples where biosolids were land-applied, and surface soil samples where no biosolids were land-applied (i.e., background samples). PFOS was detected in biosolids collected from both Decatur Utilities (405 and 418 ng/g) and 1203477 000 0201 1112 KW08 26 November 8, 2012 New York City (32 to 77 ng/g). PFOA was also detected in biosolids collected from both Decatur Utilities (59 and 128 ng/g) and New York City (8 to 20 ng/g). PFOS ranged from 715 to 1,409 ng/g and PFOA ranged from 818 to 2,531 ng/g in surface soil samples collected from fields where biosolids were land-applied. PFOS and PFOA were not detected above the detection limit o f 100 ng/g in the background samples. The land application o f biosolids ceased in November 2008. After November 2008, biosolids from the Decatur Utilities WWTP were sent to area landfills for disposal, including the Morgan County Regional Landfill. Flowever, PFC-containing leachate generated at Morgan County Regional Landfill was sent to the Decatur Utilities WWTP for treatment prior to discharge to the Tennessee River. In June 2005, leachate from this landfill was analyzed and contained a PFOS concentration of 43,200 ng/L and a PFOA concentration of 43,100 ng/L (3M 2008). The landfill leachate was tested again in April 2006 and contained a PFOS concentration of 27,400 ng/L and a PFOA concentration o f 48,700 ng/L (3M 2008). In June 2012, surface water samples were collected in the area of the Decatur Utilities WWTP outfall diffuser (Figure 1) and PFOS was detected from 2.76 to 4.31 ng/L and PFOA was detected from 1.8 to 3.08 ng/L (Appendix B). No historical sampling was previously conducted in the area o f this outfall diffuser. Surface water samples were also collected from along the west side o f the Decatur Utilities WWTP within Dry Branch in June 2000 and June 2012. In June 2000, six surface water samples were collected from the mouth o f Dry Branch and PFOS was detected from 33.05 to 65.5 ng/L and PFOA was detected from 14.45 to 31.35 ng/L (Entrix 2001). Samples collected in June 2012 from the mouth o f and upstream in Dry Branch contained 19.3 and 22.3 ng/L o f PFOS and 9.58 and 9.8 ng/L o f PFOA (Appendix B). The surface water concentrations at the outfall diffuser were below background but may not reflect the highest concentrations at the mouth o f the outfall pipe. Fish may be attracted to this location at certain times of the year. 1203477 000 0201 1112 KW08 27 November8, 2012 3.2.12 Wolverine Tube Area Wolverine Tube is located at approximate River Mile 307. Potential sources of PFCs in the Wolverine Tube sampling area include the land-application o f biosolids and discharges from historical facilities that may have used PFCs. As stated above, biosolids from the Decatur Utilities WWTP were land-applied to privately-owned agricultural land until November 2008, when the land-applied biosolids were found to contain PFCs. Two of these agricultural areas that received sludge applications are located southwest of Wolverine Tube, likely within the drainage basin for Flint Creek. In September 2008 and February 2009, EPA collected surface soil and/or surface water samples, respectively, from these agricultural areas. PFOS was detected in surface soil at 972 ng/g and PFOA was detected in surface soil at 1,598 ng/g (U.S. EPA 2009a). PFOA concentrations in surface water ranged from non-detect to 750 ng/L. PFOS concentrations in surface water ranged from non-detect to 66.3 ng/L (U.S. EPA 2009b). Surface water drainage in the vicinity of these agricultural areas appears to flow to the east, toward Flint Creek which discharges into the Tennessee River just upriver o f the Wolverine Tube sampling area. PFC-containing surface water from these agricultural areas may have discharged to Flint Creek and ultimately to the Tennessee River. Historical companies located in the Wolverine Tube sampling area that may be potential sources o f PFCs include: The Wolverine Tube facility is located upriver of the 3M Decatur facility at approximate River Mile 307. Wolverine Tube, which began operations in 1948, produced copper and copper-based alloy tubing, aluminum tubing, and extruded aluminum shapes. This facility conducted plating operations and discharged some process wastes to the Tennessee River via three outfalls (Outfalls 1 through 3). This facility may have used PFCs as a mist suppressor during plating operations. Wolverine Tube also disposed o f some wastes at BFI Morris Farms Landfill, a landfill with known PFC-containing leachate (Decatur Daily 2009a). 1203477 000 0201 1112KW08 28 November8, 2012 HCI Coatings, an industrial coatings manufacturer, was historically located along the south bank o f the Tennessee River at approximate River Mile 305.5. This company may have used PFCs and PFC-containing run-off from this facility may have discharged to the Tennessee River. Surface water samples were collected in November 2000, December 2004, July 2005, December 2006, and June 2012 in the vicinity o f the Wolverine Tube facility. Between November 2000 and December 2006, PFOS concentrations ranged from undetectable to 52.6 ng/L and PFOA was not detected above the detection limits (Hansen et al. 2002; Weston 2008a,b). PFOS was also detected in November 2000 at 51.9 ng/L at a location approximately 1.5 miles upriver o f the Wolverine Tube facility near the mouth o f Flint Creek (the creek may have received PFC-containing run-off from agricultural areas where Decatur Utilities WWTP sludge was applied). Surface water samples collected in June 2012 (Figure 1) contained 6.83 to 9.15 ng/L o f PFOS and 5.22 to 5.89 ng/L o f PFOA (Appendix B). Consistently low PFOS and PFOA concentrations at this location indicate that there does not appear to be a substantive source o f PFCs in this area. 1203477 000 0201 1112 KW08 29 November 8, 2012 4 Conclusions and Recommendations 4.1 Conclusions The recent surface water and sediment sampling together with historic surface water and sediment sampling suggests that there are multiple sources o f PFCs to the Wheeler Reservoir and the Tennessee River and its tributaries. This is based on the presence o f PFC-generating sites, other than the 3M Decatur facility, and the spatial distribution o f PFOS and PFOA in surface water samples collected in June 2012. Additional sampling is needed to evaluate effects on fish tissue concentrations as well as to develop more comprehensive surface water chemistry data for source evaluation. 4.2 Recommendations Based on the preliminary research and sampling conducted to date, a comprehensive fish and water sampling program is recommended. The purpose of comprehensive fish sampling program is to provide updated information on PFOS levels in edible fish tissue in the Wheeler Reservoir and the Tennessee River and its tributaries. The sampling methodology will be guided by previous sampling investigations for PFCs in fish tissue and surface water, as well as information evaluated by Exponent on potential sources for PFCs in the Tennessee River besides the 3M Decatur facility. 4.2.1 General Sampling Approach Sampling locations for fish collection should be similar to those previously identified in the June 2012 water and sediment sampling investigation (Figure 4). Proposed sampling areas include: 1203477 000 0201 1112 KW08 30 November 8, 2012 1. Tennessee River, River Mile 320-- Sampling reach located below Triana at approximate River Mile 320. Previously sampled by ADEM as TENR-320 in 2007, 2008, and 2009. 2. Point Mallard-- Sampling reach located on the southern shoreline o f the main channel near Point Mallard above the City of Decatur at approximate River Mile 307.5. Previously sampled by 3M in 2004 and 2006. 3. Tennessee River, River Mile 307.5-- Sampling reach located in the backwater area to the north o f the main channel near Point Mallard above the City o f Decatur at approximate River Mile 307.5. 4. Mouth o f Betty Rye Branch and Dry Branch-- Sampling reach located at the confluence o f Betty Rye Branch and Dry Branch with the Tennessee River. Sampling reach is along the southern shoreline o f the Tennessee River at approximate River Mile 303. 5. Bakers Creek Mouth-- Sampling reach located at the confluence o f Bakers Creek with the Tennessee River at approximate River Mile 301. The sampling reach extends along the southern shoreline of the Tennessee River. Previously sampled by 3M in 2004, 2006, and spring 2012. Previously sampled by ADEM as WHEL-11 in 2007, 2008, and 2009. 6.

Sampling reach is upstream of the confluence o f Fox Creek with the Tennessee River. 8. Round Island Creek Mouth-- Sampling reach along the northern shoreline of the Tennessee River at the mouth o f Round Island Creek at approximate River Mile 298. 1203477 000 0201 1112 KW08 31 November 8, 2012 9. Fox Creek Mouth-- Sampling reach along the southern shoreline o f the Tennessee River at the mouth o f Fox Creek at approximate River Mile 296. Previously sampled by 3M in 2004 and 2006. 10. Browns Ferry Nuclear Power Plant-- Sampling reach along the northern shoreline of the Tennessee River in the vicinity o f Browns Ferry Nuclear Power Plant at approximate River Mile 294. 11. Mallard Creek Mouth-- Sampling reach along the southern shoreline o f the Tennessee River at the mouth of Mallard Creek at approximate River Mile 293.5. Previously sampled by 3M in 2004 and 2006. 12. Elk River Mouth-- Sampling reach along the northern shoreline o f the Tennessee River at the mouth of Elk River at approximate River Mile 285. 13. Tennessee River, River Mile 281-- Sampling reach along the southern shoreline of the Tennessee River below the mouth of Spring Creek at approximate River Mile 281. Previously sampled by ADEM as TENR-281 in 2007, 2008, and 2009. At each sampling location, five o f each species (largemouth bass and channel catfish) should be collected, consistent with the total number targeted per reach by Weston (2012a). Surface water samples should be collected within each fish sampling area. In addition, to provide current information on PFC concentrations throughout the Wheeler Reservoir, a minimum o f 10 evenly spaced water samples should be collected along 8 cross-river transects. This transect sampling should be conducted at the following locations: 1. Transect T1-- Below Triana, coincides with the fish sampling reach located below Triana at approximate River Mile 320. 2. Transect T2-- Coincides with the fish sampling reaches at approximate River Mile 307.5. This transect will span across the main flow channel as well as the backwater area to the north of the main channel. 1203477 000 0201 1112 KW08 32 November 8, 2012 3. Transect T3-- Immediately downstream from the mouth o f Betty Rye Branch and Dry Branch, coincides with the fish sampling reach at approximate River Mile 303. 4. Transect T4-- Immediately downstream from the mouth o f Bakers Creek, coincides with the fish sampling reach at approximate River Mile 301. 5. Transect T5-- Immediately downstream from the mouth o f Round Island Creek, coincides with the fish sampling reach at approximate River Mile 298. 6. Transect T6-- Immediately downstream from the mouth o f Fox Creek, coincides with the fish sampling reach at approximate River Mile 296. 7. Transect T7-- Immediately downstream from the mouth o f Mallard Creek, coincides with the fish sampling reach at approximate River Mile 293.5. 8. Transect T8-- Below Spring Creek and the Elk River, coincides with the fish sampling reach at approximate River Mile 281. Both fish tissue and water samples should be shipped to the 3M Environmental Laboratory in St. Paul, Minnesota. Split samples (minimum o f 10 percent) should also be submitted to AXYS in Sidney, British Columbia, Canada. Fish and surface water samples should be analyzed for the following PFCs monitored as part o f 3M's NPDES permit: PFBA PFHxA PFHpA PFOA Perfluorobutane sulfonamide acid 2-(N-ethyl-PFOSA) acetic acid 2-(N-methyl-PFOSA) acetic acid 1203477 000 0201 1112 KW08 33 November8, 2012 PFBS PFHxS PFOS PFOSA. 4.2.2 Fish Sampling Methodology The fish sampling should be conducted using methods that are generally consistent with previous sampling efforts in this area (e.g., Weston 2012a). The sampling plan should include the following elements: 1. Species: Largemouth bass and channel catfish should be sampled (both species have been previously sampled). 2. Sample Types: Fish tissue should be collected to evaluate exposure to fishermen. Skin-off fish fillets should be collected in the field, as specified in Weston (2012a) based on input from ADEM. Duplicates and other quality control samples will also be collected in a manner that is generally consistent with Weston (2012a). 3. Fish Size: The sampling effort should target fish between 13-18 inches in length with a minimum length of 8 inches for largemouth bass and at least 13 inches in length for channel catfish, for consistency with ADEM and Weston (2012a) sampling. 4. Target Fish Sample Number: Five o f each species per sampling area, consistent with the total number targeted per reach by Weston (2012a). 5. Collection Method: Electrofishing using a boat-mounted electrofishing unit and trotlines will be the primary sampling methods. If necessary, electrofishing and trotlines may be augmented by other fish collection techniques such as rod and reel angling. 6. PFC Analytes: Fish tissue will be analyzed for the 11 PFCs listed above. 1203477 000 0201 1112 KW08 34 November 8, 2012 4.2.3 Surface Water Sampling Methodology Surface water sampling should be conducted using methods that are generally consistent with the June 2012 sampling conducted by Exponent. The sampling plan should include the following elements: 1. Target Sample Number: Three locations within each fish sampling area. For the cross-river transects, a minimum o f 10 evenly spaced samples will be collected over the length of the transect. 2. Collection Method: At each sampling location, grab surface water samples should be collected using a 2.5-L Niskin (polyvinyl chloride) sampler or a peristaltic pump located at approximately 0.6 o f the total water depth. At sampling stations where the average water depth is greater than 10 ft, samples should be collected at two depths, 0.2 and 0.8 o f the total water depth, consistent with previous sampling events (Weston 2012b). The shallow and deep samples collected at each location will be composited into one sample. 3. PFC Analytes: Surface water samples should be analyzed for the 11 PFCs noted above. In addition to the laboratory analyses, surface water samples should be measured in the field for the following parameters: - pH - Conductivity - Temperature - Dissolved oxygen - Turbidity. 1203477 000 0201 1112 KW08 35 5 References November8, 2012 3M. 2008.

The goal o f the program was to identify sources and the presence of PFOA in environmental media, including surface water and sediment, on- and offsite. Between June 2000 and April 2012, several surface water and sediment samples were collected in the Tennessee River and its tributaries, upriver and downriver of the 3M Decatur facility and at the 3M Decatur facility. Some o f these sampling events were in response to the MOU. Collected samples were analyzed for various perfluorinated chemicals (PFCs). In June 2012, Exponent conducted additional surface water and sediment sampling in the Tennessee River and its tributaries in areas upriver and downriver of the 3M Decatur facility. The purpose o f this investigation was to provide more current data on PFC concentrations at previously sampled locations and additional data in other locations that have not been as well characterized. 1203477 000 0201 1112 KW08 B -l 2 Site Setting and History November 8, 2012 The 3M Decatur facility covers approximately 900 acres and is located at 1101 State Docks Road in Decatur, Alabama, along the south shoreline o f Wheeler Reservoir o f the Tennessee River at approximate River Mile 300.5 (Figure B -l). Wheeler Reservoir was created by Wheeler Dam, which is located approximately 25 miles downriver o f the 3M Decatur facility at approximate River Mile 275. Wheeler Lake and its tailwaters feed into Wilson Lake located on the west side of Wheeler Dam. 3M began operations at the Decatur facility in 1961 with the construction o f a chemical manufacturing plant to produce PFC-related products. In 1962, the facility was expanded to include a film manufacturing plant. Between 1961 and 1962, 3M also constructed an onsite wastewater treatment plant (WWTP) with discharge to the Tennessee River. Dyneon, located on the southern portion o f the 3M Decatur facility, began operations in 1996. Dyneon manufactures vinylidene fluoride (VDF) and polyvinylidene fluoride (PVDF). Process wastewater generated at Dyneon is managed at 3M 's treatment plant prior to discharge to the Tennessee River. During the investigation described in this report, samples were collected in Wheeler Reservoir between River Miles 282 and 308 and in Wilson Lake at approximate River Mile 274. 1203477 000 0201 1112 KW08 B -2 3 Summary of Field Activities November 8, 2012 In June 2012, Exponent collected samples of surface water and sediment (where possible) from 12 areas in the Tennessee River and its tributaries upriver and downriver o f the 3M Decatur facility (Figure B-2). These areas were selected to evaluate potential sources o f PFCs and/or to update/supplement sampling previously conducted by others. Sampling areas, surface water sampling methodology, sediment sampling methodology, quality assurance/quality control (QA/QC) samples, and decontamination procedures are discussed in the following sections. 3.1 Sampling Areas Areas within the Tennessee River sampled in June 2012 by Exponent are shown on Figure B-2 and are listed below. Sampling was not conducted in June 2012 within Bakers Creek because the concentrations of PFCs from several potential sources in this tributary are generally known and 3M 's and Daikin's National Pollutant Discharge Elimination System (NPDES) discharges to Bakers Creek are monitored for PFCs on a regular basis. These sampling areas were proximate to: Mouth of Big Nance Creek Shoreline of International Paper Plant Shoreline o f Browns Ferry Nuclear Power Plant and near the outfall diffuser Mouth of and upstream in Mallard Creek Mouth of and upstream in Fox Creek Shoreline o f Mallard-Fox Creek Industrial Park (Industrial Park) Shoreline o f Ascend Performance Materials (APM) Mouth of and upstream in Betty Rye Branch Mouth o f and upstream in Dry Branch Shoreline west-southwest of Pryor Field Regional Airport Decatur Utilities WWTP outfall diffuser area Shoreline of Wolverine Tube. Within each sampling area, sample locations were assigned numerical global positioning system (GPS) waypoints from the boat's GPS system (GPS waypoints 115 through 152). These sample location designations are shown on Figures B-3 through B -l 1. 1203477 000 0201 1112 KW08 B -3 November 8, 2012 3.2 Surface Water Sampling Methodology Grab surface water samples were collected using a 2.5-L Niskin (polyvinyl chloride) sampler approximately 2 ft from the bottom o f the river (sediment surface) at all locations. At locations where the river depth did not allow for use of the Niskin sampler, surface water samples were collected directly with the sample container. In addition, at sampling areas where the average water depth was greater than 10 ft, a second water column sample was collected at approximately 0.2 of the total water depth. Only one shallow surface water sample was collected per sampling area. Samples were poured from the Niskin sampler directly into laboratory-supplied 1-L and 500-mL plastic bottles. The 1-L bottle was submitted to AXYS Analytical Services (AXYS) and the 500-mL bottle was submitted to Columbia Analytical Services (CAS) (Analytical Laboratory Services [ALS] Group). Prior to sample collection at each location, the total estimated depth was recorded and field parameters were measured by lowering a multi-meter probe to the desired sampling depth. Measured water quality parameters included the following: pH Specific conductivity Conductivity Temperature Dissolved oxygen Turbidity. Samples submitted to AXYS in Sidney, British Columbia, Canada, were analyzed for PFCs by Method MLA-060 (Revision 10). This analysis included the following 13 PFCs: Perfluorobutanoic acid (PFBA) Perfluoropentanoic acid (PFPeA) Perfluorohexanoic acid (PFHxA) Perfluoroheptanoic acid (PFHpA) Perfluorooctanoic acid (PFOA) Perfluorononanoic acid (PFNA) Perfluorodecanoic acid (PFDA) Perfluoroundecanoic acid (PFUnA) Perfluorododecanoic acid (PFDoA) Perfluorobutane sulfonate (PFBS) 1203477 000 0201 1112 KW08 B -4 November 8, 2012 Perfluorohexane sulfonate (PFHxS) Perfluorooctane sulfonate (PFOS) Perfluorooctane sulfonamide (PFOSA). Samples submitted to CAS in Jacksonville, Florida, were analyzed for total suspended solids (TSS) by Standard Method (SM) 2540 D and total dissolved solids (TDS) by SM 2540 C. Field parameters are shown in Table 1-1 in Attachment 1. Sampling results are shown in Tables 1-2 and 1-3 in Attachment 1. The complete analytical laboratory reports for AXYS and CAS are provided in Attachments 2 and 3, respectively. 3.3 Sediment Sampling Methodology Sediment samples were collected using a petite Ponar grab sampler (stainless-steel sampler with zinc-plated arms and a neoprene flap to prevent fine material from escaping). Sediment samples were collected from the top 0-6 in. o f sediment. Following sample collection, the sediment sample was placed in a clean container and non-sediment materials (e.g., sticks, stones, garbage, etc.) were described and removed. The samples were then placed in laboratory-supplied 250 mL and 500-mL plastic containers. The 250-mL containers were submitted to AXYS and the 500-mL containers were submitted to CAS. During sediment sampling, observations were also made and recorded regarding fish habitat features at each location. Features noted included the following: Extent to which an area is shaded (e.g., shaded by overhanging vegetation or shaded by another structure) Presence or absence o f aquatic vegetation Presence or absence of aquatic structures (e.g., dead trees, rocks, piers/floats, and beaver dams) Depth and depth changes over an area (e.g., is there a hole or sharp drop-off in an area) Backwater or area sheltered from strong currents Sediment type (e.g., sand, soft organic material, etc.). Samples submitted to AXYS in Sidney, British Columbia, Canada, were analyzed for PFCs by Method MLA-041 (Revision 09). This analysis included the 13 PFCs noted above in Section 3.2. 1203477 000 0201 1112 KW08 B -5 November 8, 2012 Samples submitted to CAS in Jacksonville, Florida, were analyzed for particle size by American Society for Testing and Materials (ASTM) Method D422, total organic carbon (TOC) by EPA Method 9060M, and total solids by EPA Method 160.3 Modified. Sampling results are shown in Tables 1-4 and 1-5 in Attachment 1. The complete analytical laboratory reports for AXYS and CAS are provided in Attachments 2 and 3, respectively. 3.4 Quality Assurance and Quality Control Samples QA/QC samples were collected during the investigation and included field duplicate, projectspecific matrix spike/matrix spike duplicate (MS/MSD), and blank samples. 3.4.1 Field Duplicates Surface water and sediment field duplicate samples were collected daily for the analysis of PFCs.

Decontamination was performed by rinsing the equipment with site (i.e., river) water and scrubbing with non-phosphate soap (e.g., Alconox Tergajet) to remove any visible residual material. The scrub brush used was a non-Teflon/non-coated brush. Scrubbing was followed by a second rinse using site water. The equipment was then rinsed with methanol followed by a final rinse with deionized/distilled water. If equipment was not immediately used after decontamination, it was placed in a clean/decontaminated container. 1203477 000 0201 1112 KW08 B -8 4 Summary of Sampling Areas November 8, 2012 4.1.1 Big Nance Creek Big Nance Creek discharges to the Tennessee River at approximate River Mile 274, downriver of the Wheeler Dam. Upstream creeks that flow into Big Nance Creek include Muddy Fork and Crow Branch (Figure B -l). Potential sources of PFCs to Big Nance Creek include the landapplication of sewage sludge (biosolids) and discharges from the City of Moulton WWTP. Surface water and sediment samples were collected from the confluence o f this creek with the Tennessee River. Sediment could not be collected at Sample Location 119 as this location contained a thick bed of leafy material and small sticks. Because sediment could not be collected at Sample Location 119, the field crew attempted to collect sediment at an alternate location, Sample Location 120. This location was closer to the Tennessee River channel and did contain enough sediment for sample collection. A summary o f collected samples is listed in Table B -l and shown on Figure B-3. Water quality parameters and sample results are presented in Tables 1-1 through 1-5 in Attachment 1. Table B-1.
