In 1978, Johnson Controls constructed the facility to manufacture, assemble and charge automobile batteries. By 1984, plant production ranged from 6,000-11,000 batteries per day. Around 1992, the plant expanded operations with current production estimated at between 14,000-22,000 batteries per day. The facility is currently listed as a RCRA large quantity generator. The facility generates hazardous wastestreams containing antimony, barium, lead and waste petroleum naphtha, which are shipped offsite for treatment or disposal. In addition, the facility reported at least 13 unpermitted releases of hazardous substances from the plant to onsite soils or sedimentation basins since 1979. The facility also reported fugitive or stack air emissions of antimony, arsenic, barium, barium compounds, carbon monoxide, hydrogen gas, lead, lead compounds, nitrogen oxides, selenium, sulfuric acid and sulfur dioxide. The site is located near the top of a small hill that slopes northwest toward Lowery Mill Creek and west toward an unnamed tributary to Lowery Mill Creek. Surface runoff from the facility collects in catch basins and travels through underground pipes to three splash pads at the heads of three sedimentation basins along the west boundary of the site. These three basins collect stormwater runoff from the site which is then discharged to two unnamed tributaries to Lowery Mill Creek. Lowery Mill Creek flows into Salem Lake . 401 OBERLIN ROAD, SUITE 1 SO, RALEIGH, NC 27605 PHONE 919-733-4996 FAX 919-715-3605 AN EQUAL OPPORTUNITY/ AFFIRMATIVE ACTION EMPLOYER· 50% RECYCLED/I 0% P0ST•C0NSUMER PAPER I I I I I I I I I I I I I I I I I I I Letter to Mr. Vorsatz Johnson Controls ESI September 30, 1998 Page2 Approximately 66,767 people are served by a drinking water intake located about 2.1 miles downstream of the site at Salem Lake. People routinely fish at the Old Greensboro Road bridge over Salem Lake, approximately 0.8 mile downstream of the site. A palustrine scrub-shrub type wetland exists along the unnamed tributary that connects Basin # I to Lowery Mill Creek, for 0.25 mile of wetland frontage, about 1200 feet west of the site. The National Wetland Inventory Maps identify 1.13 miles of wetland frontage bordering Lowery Mill Creek between the confluence of the unnamed tributary and Salem Lake. Salem Lake has 0.24 miles of marshy wetland frontage at its headwaters above the Old Greensboro Road bridge. There are approximately 43,662 people within a 4 mile radius of the site. There are two known drinking water wells within a 0.25 mile radius of the site. On August 11-13, 1997, the NC Superfund Section collected soil samples from three source areas, soil samples in the overland runoff pathway from the site. The three source areas include soils from an Acid Storage Tank area, a Lead Oxide Unloading area and a Drum Storage Area. Groundwater samples and numerous surface water and sediment samples downstream of the site were also collected to characterize any releases from the site that could impact known target receptors. Elevated levels of numerous polynuclear aromatic hydrocarbons and metals were detected in surficial soil samples collected from the three source areas at the site. Of these contaminants, benzo( a)anthracene, benzo(b/k)fluoranthene, benzo( a )pyrene, indeno( 1,2,3-cd)pyrene, dibenzo(g,h,i)perylene, arsenic and lead were found in the lead oxide unloading area soil samples or overland drainage soil samples in excess of either the August 1996 EPA Superfund Chemical Data Matrix (SCDM) human health-based soil screening benchmarks, or the August 1998 North Carolina Inactive Hazardous Sites Branch soil remediation goals (NC RG's). There are 630 employees working within 200 feet of source areas at the site. Though elevated levels of barium, copper, lead, manganese and zinc were identified in the nearest residential well about 400 feet east of the site, the levels of contaminants did not exceed their respective EPA Maximum Contaminant Levels, or State of North Carolina 2L groundwater standards, and are not considered a health risk to residents. Historic releases of barium and lead were reported in surface water samples collected from the unnamed tributary below Basin #I. The current analytical results demonstrate an observed release oflead from the site to surface water at levels that pose a significant threat to a nearby downstream wetland. In addition, historic releases of phenanthrene, fluorantliene, pyrene, benzo(a)anthracene, chrysene, benzo(b )fluoranthene, bis(2-ethylhexyl)phthalate, chromium and lead were reported in sediment samples collected from the unnamed tributary below Basin # I. The current round of samples showed decreased levels of these contaminants in sediments downstream of the site. I I I I I I I I I I I I I I I I I I I Letter to Mr. Vorsatz Johnson Controls ESI September 30, 1998 Page 3. Based on the analytical results, the site appears to be releasing lead to surface water at concentrations that could pose a significant threat to a nearby wetland below Basin # I. The NC Superfund Section therefore recommends this site for further remedial action under CERCLNSARA.

The plant was constructed in I 978 to manufacture automobile batteries. The site was undeveloped prior to 1978. In 1978, Johnson Controls constructed the facility to manufacture, assemble and charge automobile batteries. By 1984, plant production ranged from 6,000-11,000 batteries per day. Around 1992, the plant expanded operations with current production estimated at between 14, 000- 22, 000 batteries per day. Raw materials used in the production of batteries include pig lead, lead oxide, barium sulphate, carbon black and sulfuric acid. The facility is currently listed as a RCRA large quantity generator. The facility generates hazardous wastestreams containing antimony, barium, lead and waste petroleum naphtha, which are shipped off site for treatment or disposal. The wastewater treatment plant process uses sodium hydroxide to raise the pH, then precipitates with ferrous sulfate, filters to remove the large solids, and filter presses to produce the lead sludge filter cake. The facility ships filter cake and lead contaminated solid wastes off-site to lead smelters. Hazardous wastes generated during the operation are stored at the plant in 5 5 gallon drums and IO mil polyethylene bags. Hazardous wastes generated at the plant consist of pasting conveyer belts, floor sweeping compounds, fiber and plastic separators, waste paper toweling, wipe cloths, cheese cloths, work gloves, whole HEP A filters, fabric bag filters, wastewater treatment plant residue and wet scrubber (rotoclone) sludge. Wastewater treatment plant residue and rotoclone sludge are removed on a batch basis and stored in a separate container storage area, and subsequently shipped to a smelter. Disposal practices prior to 1980 are not well documented. The dry waste is containerized and segregated in a separate waste storage area, prior to shipment to a smelter. The facility operates the three surface impoundments for storm water runoff management under a general stormwater management permit NCG030224, issued on August 20, 1993. The facility has never been permitted under the National Pollutant Discharge Elimination System. The facility operates air emissions control equipment under air quality permit #00725R8, issued by the Forsyth County Environmental Affairs Office. The facility operates under the "synthetic minor source" category that places maintenance and operation restrictions on the air emissions control equipment to avoid being subject to Title V of the Clean Air Act. The facility reported at least 13 unperrnitted releases of hazardous substances from the plant to onsite soils or sedimentation basins since 1979. The facility reported fugitive or stack air emissions of antimony, arsenic, barium, barium compounds, carbon monoxide, hydrogen gas, lead, lead compounds, nitrogen oxides, selenium, sulfuric acid and sulfur dioxide. The site is located near the top of a small hill that slopes northwest toward Lowery Mill Creek and west toward an unnamed tributary to Lowery Mill Creek. Surface runoff from the facility collects in catch basins and travels through underground pipes to three splash pads at the heads of three sedimentation basins along the west boundary of the site. These three basins collect stormwater runoff from the site which is then discharged to two unnamed tributaries to Lowery Mill Creek. Lowery Mill Creek flows into Salem Lake. Approximately 66,767 people are served by a drinking water intake located about 2.1 miles I I I I I I I I I I I I I I I I I I I downstream of the site at Salem Lake. People routinely fish at the Old Greensboro Road bridge over Salem Lake, approximately 0.8 mile downstream of the site. A palustrine scrub-shrub type wetland exists along the unnamed tributary that connects Basin #1 to Lowery Mill Creek, for 0.25 mile of wetland frontage, about 1200 feet west of the site. The National Wetland Inventory Maps identify 1.13 miles of wetland frontage bordering Lowery Mill Creek between the confluence of the unnamed tributary and Salem Lake. Salem Lake has 0.24 miles of marshy wetland frontage at its headwaters above the Old Greensboro Road bridge. There are approximately 43,662 people within a 4 mile radius of the site. There are two known drinking water wells within a 0.25 mile radius of the site. On August 11°13, 1997, the NC Superfimd Section collected soil samples from three source areas, soil samples in the overland runoff pathway from the site. The three source areas include soils from an Acid Storage Tank area, a Lead Oxide Unloading area and a Drum Storage Area. Groundwater samples and numerous surface water and sediment samples downstream of the site were also collected to characterize any releases from the site that could impact known target receptors. Elevated levels bf numerous polynuclear aromatic hydrocarbons and metals were detected in surficial soil samples collected from the three source areas at the site. Of these contaminants, benzo( a)anthracene, benzo(b/k)fluoranthene, benzo( a)pyrene, indeno( 1,2,3-cd)pyrene, dibenzo(g,h,i)perylene, arsenic and lead were found in the lead oxide unloading area soil samples or overland drainage soil samples in excess of either the August 1996 EPA Superfund Chemical Data Matrix (SCDM) human health-based soil screening benchmarks, or the August 1998 North Carolina Inactive Hazardous Sites Branch soil remediation goals (NC RG's). There are 630 employees working within 200 feet of source areas at the site. The NC Superfund Section personnel collected a groundwater sample from the nearest residence. Though elevated levels of barium, copper, lead, manganese and zinc were identified in the nearest residential well about 400 feet east of the site, the levels of contaminants did not exceed their respective EPA Maximum Contaminant Levels, or North Carolina groundwater standards, and are not considered a health risk to residents. Of these contaminants, elevated levels of lead, manganese and zinc were also found in onsite source soil samples collected during this investigation. Historic releases of barium and lead were reported in surface water samples collected from the unnamed tributary below Basin # 1. The current analytical results demonstrate an observed release oflead from the site to surface water at levels that pose a significant threat to a nearby downstream wetland. In addition, historic releases ofphenanthrene, fluoranthene, pyrene, benzo(a)anthracene, chrysene, benzo(b )fluoranthene, bis(2-ethylhexyl)phthalate, chromium and lead were reported in sediment samples collected from the unnamed tributary below Basin # I. The current round of samples showed decreased levels of these contaminants in sediments downstream of the site. Based on the analytical results, the site appears to be releasing lead to surface water at concentrations that could pose a significant threat to a nearby wetland below Basin # 1. The NC Superfund Section therefore recommends this site for further remedial action under CERCLNSARA. I I I I I I I I I I I I I I I I I I I 1.0 INTRODUCTION Under authority of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) and the Superfund Amendments and Reauthorization Act of 1986 (SARA), the NC Superfund Section conducted an Expanded Site Inspection (ESI) at the Johnson Controls- Globe Battery Division site, 2701 Johnson Controls Road, Winston-Salem, Forsyth County, North Carolina. The purpose of this investigation was to collect information concerning conditions at the site sufficient to assess the threat posed to human health and the environment and to determine the need for additional CERCLNSARA or other appropriate action. The scope of the investigation included review of available file information, a comprehensive target survey, onsite and offsite reconnaissances (May 8, 1997, June 3, 1997, July 30, 1997 and March 4, 1998), interviewing neighbors and collecting environmental samples (August 11-13, 1997). 2.0 2.1 SITE DESCRIPTION Location The Johnson Controls-Globe Battery Division ("Johnson Controls") site is located at 2701 Johnson Controls Road, Winston-Salem, Forsyth County, North Carolina (Fig. 1). The coordinates forthe site are 36° 07' 09" North Latitude and 80° 09' 40" West Longitude (Ref. 1). The two year- twenty four hour rainfall for Forsyth County averages 3.5 inches (Ref. 2). Normal annual total precipitation averages 48 inches, while mean annual lake evaporation averages 3 8 inches, therefore, net annual precipitation averages 10 inches near the site (Ref. 3). 2.2 Site Description Johnson Controls operates an lead-acid automotive battery manufacturing facility at the 7 5. 15 acre site. The facility consists of a large manufacturing plant, a trailer maintenance building, a battery storage facility, a concentrated acid storage and acid mixing building, a wastewater pretreatment system, and offices. The site layout is presented in Figure 2. Asphalt parking surfaces, bare soil, grass lawn, and woods comprise the soil cover around the facility. A chain link fence encloses the facility with access controlled by a security guard (Ref 4). The site is located near the top of a small hill that slopes northwest toward Lowery Mill Creek and west toward an unnamed tributary to Lowery Mill Creek (Figs. 1, 3). Surface runoff from the main facility collects in catch basins and travels through underground pipes to three splash pads at the heads of three sedimentation basins along the west boundary of the site. These three basins collect storm water runoff from the site, allowing particulates to settle out before being discharged through a large diameter vertical overflow pipe in the dam to unnamed tributaries (Ref. 4; Fig. 3; Photos 1-4). Basin # 1 discharges to a small unnamed intermittent tributary that directs runoff northwest to Lowery Mill Creek. Basins #2 and #3 discharge to a second unnamed intermittent tributary that directs runoff north to Lowery Mill Creek. The stormwater retention basins lie outside the fenced areas of the site (Ref. 4). Light commercial industry and residences bound the site along 3 I JOHNSON CO,~TRDLS . ~ I SL!

By 1984, plant production ranged from 6,000-11,000 batteries per day (Ref 5, p. B-2). Around 1992, the plant expanded operations with current production estimated at between 14,000- 22,000 batteries per day (Ref 4). Raw materials used in the production of batteries include pig lead, lead oxide, barium sulphate, carbon black and sulfuric acid (Ref 5, pp. B-l ,B-2). The wastewater pretreatment process uses sodium hydroxide to raise the pH, then precipitates with ferrous sulfate, filters to remove the large solids, and filter presses to produce the lead sludge filter cake. The facility ships filter cake and lead contaminated solid wastes off-site to lead smelters (Ref 4). The treated wastewater is either recycled back through the operation (in the case of the lead oxide mill) or discharged to the City ofWinston-Salem publicly owned treatment works (POTW) (Ref 4, p. 1). Hazardous wastes generated during the operation are stored at the plant in 5 5 gallon drums and 10 mil polyethylene bags. Hazardous wastes generated at the plant consist of pasting conveyer belts, floor sweeping compounds, fiber and plastic separators, waste paper toweling, wipe cloths, cheese cloths, work gloves, whole HEP A filters, fabric bag filters, wastewater treatment plant residue and wet scrubber ( rotoclone) sludge. Wastewater treatment plant residue and rotoclone sludge are removed on a batch basis and stored in a separate container storage area, and subsequently shipped to a smelter (Ref 5, pp. C-1 ). Disposal practices prior to 1980 are not well documented. The dry waste is containerized and segregated in a separate waste storage area, prior to shipment to a smelter. Since 1980, the facility has generated and shipped offsite hazardous wastestreams containing antimony, barium, lead and waste petroleum naphtha. The following table summarizes available file information on facility shipments. Table 1.

On October 8, 1981, the USEP A withdrew the facility from its active permit file, indicating the site activities no longer involved storage of hazardous wastes (Ref 7). On November 9, 1981, the USEPA reclassified the site as a generator and interim status storer of hazardous wastes (Ref 8). On December 2, 1981, a RCRA Interim Status Inspection cited the facility for failure to maintain personnel training records and job descriptions and failure to adopt an emergency contingency plan (Ref 9). A December 1984 RCRA Interim Status Inspection noted surface water runoff as a concern (Ref I 0). Johnson Controls submitted an RCRA Part B application in I 984 for permission to construct a hazardous waste storage area (Ref 5). Johnson Controls withdrew its RCRA Part B application opting to establish an alternative means of disposal for hazardous wastes instead of storing hazardous wastes onsite for more than 90 days (Ref 11 ). The facility is currently listed as an RCRA large quantity generator (Ref 12). On May 22, 1984, the North Carolina Superfund Section conducted a Preliminary Assessment of the facility that recommended no further action under CERCLA (Ref 13). On September 12, 1990, NUS Corporation, under contract with the EPA, conducted a Phase I Site Screening Investigation of the facility, which recommended the site progress to a Phase II Site Screening Investigation (SSI) (Ref 10). On May 9, 1991, Greenhorne & O'Mara, Inc., under contract with North Carolina Superfund Section, conducted a Phase II SST, that included collection and analyses of nine (9) environmental samples at the site. The Phase II SST identified releases from the site and recommended that the Johnson Controls site progress to the next phase of the pre-remedial process (Ref 14). On August 11-13, 1997, the North Carolina Superfund Section conducted an Expanded Site Inspection (ESI) which included collection of on-site soil samples, off-site surface water and sediment samples and off-site drinking water well samples (Ref 15). The facility operates the three surface impoundments for storm water runoff management under a general stormwater management permit NCG030224, issued by the state on August 20, 1993 (Ref 16). There are no limitations or industry standards stated in the general permit. The facility uses the sample results to assess the effectiveness of its stormwater management program. The facility has never been permitted under the National Pollutant Discharge Elimination System (Ref 16). The facility was granted Industrial User Pre-treatment discharge permit # I 044 beginning October I, 1978. The permit authorizes discharge of wastewater from the facility pre-treatment system and sanitary sewer sources. The wastestreams originate from battery wash, laundry, showers and cooling tower blowdown. The permit places restrictions on levels of copper, lead, nickel, chromium, cadmium and zinc discharged to the Winston-Salem/Forsyth County publicly owned treatment works (POTW) (Ref 48). The facility reported at least 13 unpermitted releases of hazardous substances from the plant since 1979. In I 979, the company reported a 3,000 gallon spill of sulfuric acid to the plant 8 I I I I I I I I I I I I I I I I I I I property, which was neutralized, shoveled into steel drums and shipped to a municipal landfill in Forsyth County. They also reported a release of lead oxide dust covering about I acre which occurred while changing filter bags from air ventilation equipment at the plant (Ref. 17). On August 11, 1981, approximately 1,000 gallons oflead oxide and lead sulphate containing wastewaters spilled to sedimentation basin # I (Ref. 17, p. 2) . The facility removed and shipped 324 tons of lead contaminated soil from the basin and disposed the soil to the RCRA landfill in Pinewood, S.C. (Ref. 18, p. 18). An unknown amount spilled from a leaking valve in a sulfuric acid transfer line in 1996 (Ref 4). According to the EPA's Toxic Release Inventory, the facility reported discharges to surface water of 250 pounds of lead in 1987, I 00 pounds oflead compounds in 1988, 250 pounds oflead compounds in 1989, 5 pounds oflead in 1990, 5 pounds of lead compounds in 1991, 1992 and 1993, and 10 I pounds oflead compounds in 1994. The facility reported a one-time release of 114 pounds oflead compounds to a surface impoundment in 1995 (Appendix A). The facility operates air emissions control equipment under air quality permit #00725R8, issued by the Forsyth County Environmental Affairs Office. The facility operates under the "synthetic minor source" category that places maintenance and operation restrictions on the air emissions control equipment to avoid being subject to Title V of the Clean Air Act (Ref. 19). The permit regulates roughly 49 lead and particulate point source emissions according to lead-acid battery industry standards (Ref 19, 20). On September 18, 1996, the facility received one violation due to visible emissions released from a failed baghouse. There are no current violations reported at the facility (Ref.20). The facility reported fugitive or stack air emissions of antimony, arsenic, barium, barium compounds, carbon monoxide, hydrogen gas, lead, lead compounds, nitrogen oxides, selenium, sulfuric acid and sulfur dioxide. The following table summarizes available information on air emissions from the facility.

These three sources include contaminated soils at the acid storage tank area, the lead oxidJ unloading area and I the drum storage area. All source samples were collected according to the May ) 996 EPA Environmental Investigations Standard Operating Procedures and Quality ~ssurance Manual. Johnson Controls, through RMT Consultants of Greenville, S.C, received f Plit samples of all environmental samples collected during the August 1997 Expanded Site 11spection sampling investigation (Ref 15). \ The sampling plan was chosen to determine the presence of contaminants at the three I identified potential site source areas (Ref 21 ). Source sample locations are described in Table 3 and shown in Figure 3. I Lead deposited by fugitive air emissions easily adsorbs to clay-rich soils. Since air emissions could influence background soil lead concentrations, the sample plan incorpora!ed a background location from geologically similar soils least affected by emissions from the site (Ref 5, Page B-6; Ref 21 ). A background soil sample and duplicate background soil sample were collected from surficial soils located in a wooded area northwest of the site (Ref 15). Table 3.

The US EPA arranged for analyses and shipment of all soil samples to laboratones participating in the US EPA Contract Laboratory Program (CLP). The CLP labdratories analyzed the soil samples for inorganic analytes (Target Analyte List), purgeable and ex~ractable organics compounds (Target Compound List), as specified in the CLP Statement of Work. \us EPA Special Analytical Services requested the CLP laboratory perform Toxicity Characteristic Leaching Procedure for inorganics (TCLP-Metals) per EPA Method 1311. US EPA Region IV, Sciende and Ecosystem Support Division (SESD) or its contractors validated and attached Data Qualificir Reports to the analytical results provided to the NC Superfund Section. Complete copies of the v~lidated data and Data Qualifier Reports were also provided to Johnson Controls (Ref 22) and arb attached in the Appendix B of this report. \ EPA considers a contaminant "significantly above background", if detected at concentrations equal to, or greater than three times the background concentrations, or if detected in\ the sample, but not detected in the background. Routine sampling and analysis variations can introduce a degree of error into the analytical data. Data validation checks the usability of the analytical dta for HRS and identifies the error (bias) present. The validation process assigns qualifiers, such Js "J", to biased data. For example, "J" qualified results indicate the sample concentrations are estimated, but may be used to determine an observed release. Where "J" qualified results are reported,\EPA guidance directs the user to detennine the actual sample bias for that compound and arithmetically manipulate the sample results by a predetennined factor, if appropriate. The new results are then\used to decide if the compound in question is "significantly above background". The EPA guidance on using "J" qualified data is attached as Ref 23 . Where multiple background samples were 1collected, the 1 1 I I I I I D I I I I g H I I I I I I I determination whether contaminants detected were "significantly above backgroun " was made based on the higher concentration of the detected contaminant in either of the backgrohnd sample(s). The initial data review revealed quality control problems with the T AL anal~es generated for onsite soil samples by the CLP laboratory (Ref 24). The US EPA Region IV requested the CLP laboratory generate a new chain-of-custody, and submit the samples to the Scienpe and Ecosystem Support Division (SESD) inorganics laboratory in Athens, Georgia for reanalyses. The CLP laboratory reanalyzed the original extracts using furnace atomic absorption for 1Jad only, and then submitted the samples and new sample results to EPA SESD-Athens. Both the C~P laboratory and EPA-SESD maintained proper chain-of-custody for the onsite soil samples (Ref :115). EPA-SESD reanalyzed the samples for T AL inorganics in the Athens, Georgia laboratory following EPA standard laboratory procedures (Ref 26). A copy of all three sets of analytical results is attached in Appendix B. EPA-SESD validated the T AL sample results and submitted the results to t~e NC Superfund . I Section for review. No significant quality control problems were noted in the T AL sample results submitted by EPA-SESD. The EPA SESD instructed the NC Superfund Section \to use the SESD analytical results for evaluating TAL contaminants in onsite soil samples (Appendix B). 3.1 Source Areas 3.1.1 Acid Storage Tank Area As noted previously, the facility reported at least two spills of sulfuric acid at the facility. In I 979, the company reported a 3,000 gallon spill of sulfuric acid to the plant proJerty, which was neutralized, shoveled into steel drums and shipped to a municipal landfill (Ref 1\7). The facility remediated the I 996 spill by lime application to surface soil, but did not excavate c<l>ntaminated soil due to the small scale (Ref 4, p. 2). A composite surface soil sample (JC-SS-02) c~llected near the acid storage tank area in I 992 exhibited elevated levels of arsenic and calcium, compared with the background soil sample (JC-SS-01). A soil boring, advanced to 11 feet below gra~e near the acid storage area (JC-SB-02) in 1992, also exhibited elevated concentrations of arsenic and calcium, compared with the background soil boring (JC-SB-OJ) (Ref 14, p.2, Table I, Figu~e 2). On August 13, 1997, the NC Superfund Section collected surface soil graJ samples in the vicinity of the Acid Storage Area (JB-010-SL), the Acid Transfer Line (JB-003tSL), the Acid Mixing/Formation Area (JB-004-SL), and at the head of a drainage pipe between the Acid Storage and Battery Storage Areas (JB-005-SL) (Table 3; Figure 3). The samples were tollected using precleaned stainless steel sampling scoops and pyrex pans. The soil types varied frorri a light brown, medium to coarse-grained sand to a dark brown, fine-grained silty sand or clayey sa~d (Ref 15, p. 17-19; Photos 7, 13). On August 13, I 997, the NC Superfund Section collected a background surface1 soil grab (JB- 00 I-SL) sample from a wooded area, approximately 800 feet northwest of the main facility. The soil background soil sample was collected from a location least likely to be affected by dmissions from the site and from a soil profile similar to source soil samples collected at the site\ A duplicate background surface soil grab sample (JB-10 !-SL) was collected from the same locatioA to determine the amount of sample handling variability. The soil type was medium brown, fine to m~dium-grained silty sand (Ref I 5, p. 17; Photo 6). As shown in Table 4, eighteen inorganic analytes were 12 I I I I I I I I I I I I I I I I I I I Table 4.

The low variability noted between the two background soil samples (less then 20"/o Relative Percent Deviation in all 18 analytes) provides evidence of good field soil sampling technique, and suggests a strong confidence in the laboratory analytical precision for the soil matrix (Appendix B). Compared to the background soil samples, the surficial soil grab sample (JB-003-SL) exhibited elevated levels of calcium (3,000 mg/kg) and sodium (600 mg/kg) near a historic spill at the Acid Transfer Line. Compared to the background soil samples, surficial soil grab sample (JB-004- SL) exhibited elevated levels of calcium (2,100 mg/kg), lead (130 mg/kg), manganese (1;100 mg/kg), molybdenum (4.2 mg/kg) and zinc (140 mg/kg) in a drainage swale near the Acid Mixing/Formation Area. Compared to the background soil samples, surficial soil grab sample (JB-005-SL) exhibited elevated levels of calcium (5,800 mg/kg), molybdenum (8.2 mg/kg) and strontium (26 mg/kg) at the head of a drainage pipe between the Acid Storage and Battery Storage Areas. Compared to the background soil samples, surficial soil grab sample (JB-010-SL) exhibited an elevated level of zinc (430 mg/kg) at the comer of the Acid Storage Building. None of the contaminant concentrations found in these samples exceed the August 1996 EPA Superfund Chemical Data Matrix (SCDM) human health-based soil screening benchmarks, or the North Carolina Inactive Hazardous Sites Branch soil remediation goals (NC RG's) (Refs. 27, 28). The sample points covered an triangularly shaped area 50 feet x 150 feet x 150 feet, or 3,454 square feet (Fig. 3; Ref. 15) Overland runoff from this area is directed north underneath the main facility to a splash pad where it discharges to surface soils (Fig. 2) . From there, the overland runoff crosses open grass- covered soil for about 100 yards to a culvert that directs the drainage under an asphalt drive. The culvert discharges to a drainage swale that directs the runoff for another 100 yards to Basin 3. Two surface soil grab samples were collected in the overland runoff pathways between the Acid Storage Area and Basin 3-one soil sample about 25 feet below the splash pad, north of the main facility (JC- 011-SL), and a second soil sample about 10 feet downgradient of the culvert of the asphalt drive (JC- 012-SL) (Table 3; Figure 3; Ref. 15, pp. 17-18). The soil collected below the splash pad was a light brown, fine to medium-grained sand deposited in two small bars in the overland runoff pathway. The soil collected below the culvert was a red-brown, silty clay with little fine to medium-grained sand deposited in a small bar formed by an eddy current below a pile of vegetation (Ref. 15). Compared to the background soil samples, no elevated levels of either TCL or T AL contaminants were identified in the soil grab samples from the overland runoff pathway connecting the north end of the facility to Basin 3 (Appendix B; Table 4; Photos 14, 15). 3.1.2 Lead Oxide Unloading Dock Lead oxide is unloaded from train cars or trucks at the east side of the main facility (Ref. 4; Fig. 2). Prior to the ESI, no samples had been collected near the lead oxide unload point. In 1980, the facility reportedly used the area for hazardous waste storage (Ref. 7, p. 13). According to the Kirk-Othmer Encyclopedia of Chemical Technology, the following metals are reportedly present in lead alloys used in automotive batteries: antimony, arsenic, barium, calcium, 14 n I I I I I I I I n I I I I I I I I runoff pathway that discharges to Basin I (Appendix B; Table 4). The levels ofbenzo(a)anthracene, benzo(b/k)fluoranthene, benzo(a)pyrene and indeno (1,2,3- cd)pyrene found in the overland runoff pathway soil sample exceeds either the August I 996 EPA Superfund Chemical Data Matrix (SCDM) human health-based soil screening benchmarks, or the August 1998 North Carolina Inactive Hazardous Sites Branch soil remediation goals (NC RG's) (Refs. 27, 28). Results exceeding EPA SCDM benchmarks are highlighted in bold above and in Table 4. 3.1.3 Drum Storage Area In 1980, the facility reportedly stored hazardous waste at the southeast corner of the site (Ref. 7, p. 13). In a May 1991 reconnaissance, Greenhorne and O'Mara, Inc. noted that materials such as plastic battery cases, aluminum flake paste, battery terminals, 55-gallon drums of petroleum-based lubricants and broken battery parts were stored in this area (Ref. 14, p. 4). A composite soil sample collected at that time near a loading dock/drum storage area (JC-SS-03) exhibited elevated levels of calcium and lead (Ref. 14, p. 2, Table I, Figure 2). On August 13, I 997, the NC Superfund Section collected two surface soil grab samples (JB- 008-SL and JB-009-SL) from the former drum storage area (Table 3; Figure 3). The soil in this area was light brown, fine to medium-grained sand or silty sand (Ref. 15, p. 21; Photos 11, 12). Compared to the background soil samples, the surface soil grab sample (JB-008-SL) exhibited elevated levels oflead (94 mg/kg), manganese (1,500 mg/kg) and potassium (6,900 mg/kg) near the railroad tracks. Likewise, the surface soil grab sample (JB-009-SL) exhibited elevated levels of manganese (1,100 mg/kg) near a yellow fire hydrant (Appendix B; Ref. 15, p. 21). None of the contaminant concentrations found in this area exceed the August 1996 EPA Superfund Chemical Data Matrix (SCDM) human health-based soil screening benchmarks, or the August I 998 North Carolina Inactive Hazardous Sites Branch soil remediation goals (NC RG's) (Refs. 27, 28). The sample points cover an area 200 feet long by 10 feet wide, or 2,000 square feet (Figure 3; Ref. 15, p. 21). 3.2 Conclusions The August 1997 analytical results found elevated levels of phenanthrene, fluoranthene, pyrene, benzo(a)anthracene, chrysene, benzo(b/k)fluoranthene, benzo(a)pyrene, indeno(l,2,3- cd)pyrene, benzo(g,h,i)perylene, carbazole, arsenic, calcium, lead, manganese, total mercury, molybdenum, potassium, sodium, strontium and zinc in surficial soil samples collected from three source areas at the site. Of these contaminants, benzo(a)anthracene, benzo(b/k)fluoranthene, benzo(a)pyrene, indeno(l,2,3-cd)pyrene, dibenzo(g,h,i)perylene, arsenic and lead found in the lead oxide unloading area soil samples exceed either the August 1996 EPA Superfund Chemical Data Matrix (SCDM) human health-based soil screening benchmarks, or the August 1998 North Carolina Inactive Hazardous Sites Branch soil remediation goals (NC RG's). 16 I I I I I I I I I I I I I .~ I I I A soil sample from the overland runoff pathway connecting the site to Basin 1 exhibited elevated levels of phenanthrene, fluoranthene, pyrene, benzo(a)anthracene, chrysene, benzo(b/k)fluoranthene, benzo(a)pyrene, indeno(l ,2,3-cd)pyrene , benzo(g,h,i)perylene and lead. The levels of benzo(a)anthracene, benzo(b/k)fluoranthene, benzo(a)pyrene and indeno (1,2,3- cd)pyrene exceed either the August 1996 EPA Superfund Chemical Data Matrix (SCDM) human health-based soil screening benchmarks, or the August 1998 No.rth C\lrolina Inactive Hazardous Sites Branch soil remediation go~ls (NC RG's). ;,: 4.0 GROUNDWATER PATHWAY 4.1 Hydrogeology Forsyth County is located in the Milton Belt of the Piedmont Physiographic Province (Ref. 30). The Piedmont Province is typically underlain by three zones; (I) a regolith zone (2) a transition zone and (3) underlying fractured crystalline bedrock. The regolith zone is composed of saprolite ( clay rich residual materials derived from inplace weathering of bedrock), alluvium ( deposits of unconsolidated sediments by streams and rivers) and soil (the uppermost layer called the natural medium for plant growth) (Ref. 31, p. 7-8). The transition zone is where the unconsolidated material grades into bedrock consisting primarily of saprolite and partially weathered bedrock (Ref. 31, p. 9). The fractured bedrock has a crystalline texture with many closely spaced fractures near the bedrock surface. Fracture frequency and size decrease with depth due to increasing lithostatic pressure (Ref. 31, p. 20). Biotite gneiss and schists comprise the bedrock of the Milton Belt (Ref. 30). Recharged by rainfall, groundwater stores in the regolith zone and gradually percolates into the transition and fractured bedrock zones (Ref. 31 ). Both the transition zones and the fractured bedrock zones act as transfer zones for groundwater. However, most wells are cased beyond the transition zone into bedrock (Ref. 31 ). The fractures in the bedrock act as conduits that serve to transfer water to discharge points such as wells (Ref. 31 ). The depth to groundwater under the site is about 60 feet below grade, based on the difference between the onsite surface elevation (903 feet ams!) and the elevation of the closest known groundwater seep (844 feet ams!) (Figures 3, 4-1 ). A nearby resident, Mr. Otis Crews, reported the depth to groundwater in his well at 50 feet below land surface (Ref. 15, p. 20). Groundwater flow would be expected to follow gravity and topography from areas of high to low elevation. Groundwater at the site is expected to flow west and north towards the unnamed tributaries of Lowery Creek and Lowery Creek (Figure 2). 4.2 Groundwater Targets Most of the residents within a 4.0 mile radius of the site obtain their water from the Winston- Salem/Forsyth County Water System. Forsyth County operates a surface water intake at the Salem Lake dam, approximately 2.1 miles downstream of the site, that provides the drinking water for the 17 I I I I I I I I I I I I I I I I I I I Winston-Salem/Forsyth County municipal system (Ref. 32; Fig. 1; Photo 34). The system provides drinking water for the city of Winston-Salem, the towns of Clemmons, Kernersville and Rural Hall and for parts of rural Forsyth County (Ref 32). The city of Walkertown obtains drinking water from groundwater wells located between 3 and 4 miles from the site. The municipal water system collects groundwater from four wells, screened at 175 feet and deeper. The Winston-Salem/Forsyth County municipal water system provides a backup supply for the city of Walkertown (Ref. 33; Fig. 1). The Yorktown Subdivision operates a community well that serves 274 residents, approximately 2.6 miles southwest of the site. The Green Acres Mobile Home Court operates a community well that serves 40 residents, approximately 3.8 miles north of the site (Ref 49). A windshield survey and review of the available Forsyth County Water Line maps identified three wells within a 0.5 mile radius of the site that currently use groundwater as their drinking water supply. The number of houses within a 0.5 -4.0 mile radius that depend on private groundwater wells for their drinking water supplies was estimated by multiplying the number of houses in this sector that do not have access to municipal water supply lines by 2.40, the 1990 US Census average of persons per household for Forsyth County (Ref. 34; Figure 1). The nearest well is adjacent to the Henry Moore residence at 263 5 West Mountain Road, approximately 400 feet east of the site (Ref. 15, p. 20; Figure 3). Table 5.

On August 13, 1997, the NC Superfund Section collected two groundwater samples from two nearby drinking water wells. The first sample (JC-00 I-PW) was collected from the Henry Moore residence at 2635 West Mountain Road, about 400 feet east of the facility. The second sample (JC- 002-PW) was collected from the Otis Crews residence, about 2100 feet southwest of the facility. The 19 I I I I I I I I I I I I I I I I I I Superfund Section purged both wells for 15 minutes before sampling the groundwater, and field tested the samples for pH, conductivity, temperature, turbidity and total dissolved solids (TDS) (Ref 15, p. 20; Figure 4-1 ). On August 13, 1997, the NC Superfund Section collected a water sample from a groundwater spring located about 1200 feet west and downgradient of the facility (Figure 4-1 ). The spring sample was collected to determine if groundwater below the facility was discharging contaminants to the surface water pathway. Due to the low discharge rate from the spring, the sample was collected by digging a 2-foot diameter basin in the overland runoff path below the spring to collect the runoff After recharging the collection basin long enough to settle the solids, the Superfund Section collected an aqueous sample (JC-005-SW). After sampling, the aqueous sample from the basin was field tested for pH, conductivity, temperature, turbidity and TDS. A soil sample was collected of a shallow bar located in the overland path below the spring, following collection of the aqueous samples. The soil was an olive-gray, medium to fine-grained sand and silt mix with a moderate organic content and a slight decay odor. The soil sample was labeled "JC-005-SD" (Ref 15, p. 12, 15, 16; Photo 21 ). 4.4 Groundwater Analytical Results Numerous quality control samples were collected during the sampling event to verify the integrity ofthe sampling and handling procedures. A pre-preservative blank (JC-001-PB) and post- preservative blank (JC-002-PB) were prepared in the field to determine if any Target Analyte List contaminants were introduced into the aqueous samples during preservation. The analytical results did not detect any Target Analyte List inorganic contaminants at concentrations above the contract required detection limits in the preservative blanks. Two sets of volatile organic aqueous trip blanks (JC-00 I-TB and JC-002-TB) were prepared in the field prior to sampling. The trip blanks were placed inside each of the sampling vans to determine if any volatile organic contaminants were introduced into the samples during the entire sampling trip. The analytical results did not detect any Target Compound List volatile organic contaminants at concentrations above the contract required detection limits. A volatile organic soil trip blank (JC-003-TB) was prepared before arrival at the site. The soil trip blank was prepared following EPA procedures using oven-baked play sand and organic free water. The trip blank was placed inside a sampling team van to identify any Target Compound List volatile organic contaminants introduced into the soil samples during the sampling event. The analytical results detected a qualitative hit of toluene at a concentration (2 Jug/kg) below the contract required detection limit (IO U ug/kg). Overall, the quality control samples verify that Target Analyte List and Target Compound List contaminants were not introduced into the aqueous samples during the sample event (Ref 15, pp. 1-2; Appendix B). Compared to the background private well sample collected at the Otis Crews residence (JC- 002-PW), a drinking water well sample (JC-00 I-PW) collected from the Henry Moore residence well exhibited elevated levels of barium (31 ug/1), copper ( 490 ug/1), lead (I I ug/1), zinc (26 ug/1) and manganese (8 J ug/1). The well sample from the Henry Moore residence exhibited a pH of6.02@ 19.9 ° Celsius, a specific conductivity of 57.1 uS, TDS of 28.0 mg/I, and turbidity of 0.4 Nephelometric Turbidity Units (NTU). None of the contaminants exceed their current August 1996 20 I I I I I I I I I I I I I I I I I I I EPA SCDM drinking water benchmarks, or State of North Carolina groundwater standards (Table 7-1; Appendix B; Refs. 27, 35). Compared to the background surface water sample from the unnamed tributary (JC-00 I-SW), an elevated concentration of vanadium (6 J ug/1) was detected in the aqueous sample (JC-005-SW) collected below the spring. The concentration of vanadium found in the spring sample does not exceed the applicable August 1996 EPA Superfund Chemical Data Matrix benchmark. There are no current State of North Carolina groundwater standards for vanadium (Ref 35). The aqueous sample from the spring exhibited a pH of 6. 78 @23. I ° Celsius, a specific conductivity of 79. 5 uS, TDS of 41.6 mg/I, and turbidity of 5.1 Nephelometric Turbidity Units (NTU) (Table 7-1; Appendix B; Ref 15; Ref 27). No elevated levels of T AL or TCL analytes were detected in the soil sample (JC-005-SD) collected below the spring (Table 7-2). 4.5 Groundwater Pathway Conclusions On August 13, 1997, The NC Superfund Section personnel collected a groundwater sample from the nearest residence (JC-001-PW). Compared to the background well sample, elevated levels of barium, copper, lead, manganese and zinc were identified in the nearest residential well about 400 feet east of the site. Of these contaminants, elevated levels of lead, manganese and zinc were also found in onsite source soil samples collected during this investigation. Fortunately, the levels of contaminants did not exceed their respective EPA SCDM drinking water benchmarks, or State of North Carolina groundwater standards. Results of well samples were reviewed by a toxicologist with the North Carolina Occupational and Environmental Epidemiology Section, who concluded that the water should be considered safe for drinking, cooking and bathing purposes. The well owners were notified of the results and recommendation for continued normal usage (Ref 36). Since the nearest well could not be visually observed (i.e. a subsurface buried wellhead), relevant information on the well construction method could not be obtained. Due to its age, there was no available well log information filed with the NC groundwater section. Therefore, it is not clear whether the contaminants resulted from degradation of materials used in the construction of the older well, or whether they originally migrated from the site. The spring sample contained an elevated level of vanadium. Since vanadium was not detected in onsite sources or in surface water runoff samples from the site, it is not believed to have migrated from the site. 5.0 SURFACE WATER PATHWAY 5.1 Hydrology The site is located near the top of a small hill that slopes northwest toward Lowery Mill Creek and west toward an unnamed tributary to Lowery Mill Creek (Figs. I, 3, 4-1 ). Surface runoff from the main facility collects in catch basins and travels through underground pipes to three splash pads at the heads of three sedimentation basins along the west boundary of the site. These three basins collect storm water runoff from the site, allowing particulates to settle out before being discharged 21 I I I I I I I I I I I I I I I I I I I through large diameter vertical overflow pipes in each dam to unnamed tributaries (Ref 4; Fig. 3; Photos 1-4). Basin # 1 discharges to a small unnamed intermittent tributary that directs runoff northwest to Lowery Mill Creek. Basins #2 and #3 discharge to a second unnamed intermittent tributary that directs runoff north to Lowery Mill Creek. The stormwater retention basins lie outside the fenced areas of the site (Ref 4). The three sediment collection basins are located on the slope of the small hill, immediately downgradient of the site (Figs 3, 4-1 ). Consequently, the two tributaries that receive drainage from these basins follow the decline of the slope with flow concentrated in irregularly shaped, deeply carved, permanent channels. Since the recharge area draining into these channels near the site is small and interrupted by the sedimentation basins, the flow of water into these tributaries is intermittent. However, the grade of the channel creates enough current to transport most of the finer-grained sediments downgrade to the transition zone near the bottom of the hill. The transition zone is marked by a change in the grade of the hill, reducing the current energy. At these transition zones, the intermittent tributaries deposit the finer-grained sediments in the original stream channel, filling the original stream bed and creating a braided stream that exhibits an irregular sheet flow pattern (Photo 22). These transition zones correspond to wetland areas shown in Figures 3 and 4-1. There is sufficient upland drainage area above the transition zones to create perennial flow within the wetlands (Figure 4-1 ). On June 3, 1997, Mr. John Thomas of the United States Army Corps of Engineers, surveyed the two main tributaries below sedimentation Basins # 1, # 2 and # 3. Mr. Thomas identified two wetland areas with boundaries originating near the general transition zones (Ref 37, 38; Figure 4-1). The wetland area boundaries occur very close to the 100 year floodplain boundary for Lowery Mill Creek (Ref 39). Mr. Thomas concluded that jurisdictional wetlands are present at these locations. Under current EPA policy, the probable point of entry (PPE) of contamination to surface water begins at the head of either wetland along the tributaries. The flow in either of the two first segments averages 1.0 cubic feet per second (cfs). Runoff from Basin #1 travels about 1,200 feet overland to the first PPE (PPE1), and about 900 feet from Basins #2 and #3 to the second PPE (PPE2) (Figure 4-1). The highest scoring overland flow pathway was used to evaluate the site --from Basin # I to the first PPE (PPE1). The first segment of the surface water pathway would therefore extend from the beginning of the wetland downstream 0.13 miles from PPE1 to the mouth of the unnamed tributary on Lowery Mill Creek. The second segment of the surface water pathway continues along Lowery Mill Creek, and extends 0.6 miles downstream to the headwaters of Salem Lake, near the Old Greensboro Road bridge (Figures 1; 4-1 ). Lowery Mill Creek exhibits a characteristic meandering pattern common to mature streams with strongly eroded banks and deep pools on the outer bends and depositional point bars on the inside of the bends (Photo 28). Each bend of the meander is typically separated by a riffle. The flow within the second segment averages 9.0 cfs. Lowery Mill Creek is a class WS-III stream, protected as a water supply and suitable for aquatic life propagation and survival, fishing, wildlife, 22 I I I I I I I I I I I I I I I I I I I secondary recreation, and agriculture (Ref 40, 41 ). The third segment of the surface water pathway begins at the headwaters of Salem Lake near the Old Greensboro Road bridge and extends 1.4 miles downstream to the Salem Lake Dam. Salem Lake is a Class WS-III lake, protected as a water supply and suitable for aquatic life propagation and survival, fishing, wildlife, secondary recreation, and agriculture. Salem Lake discharges to Salem Creek with a flow estimated to be 27 cfs (Ref 40, 41 ). The fourth segment of the surface water pathway begins in Salem Creek below the Salem Lake Dam and extends 12. 9 miles downstream to the end of the 15 mile target distance limit. Salem Creek is a Class C water suitable for aquatic life propagation and survival, fishing, wildlife, secondary recreation, and agriculture. The flow for this segment was estimated to be 71 cfs near the end of the segment (Ref 40, 41 ). 5.2 Surface Water Targets Forsyth County operates a surface water intake at the Salem Lake dam, approximately 2.1 miles downstream of PPE1, that provides the drinking water for the Winston-Salem/Forsyth County municipal system (Ref 32; Fig. I; Photo 34). The system provides drinking water for the city of Winston-Salem, the towns of Clemmons, Winston-Salem and Rural Hall and for parts of rural Forsyth County (Ref 32). The population served by the entire system is reportedly 222,557 people, with an estimated 30% contribution from the Salem Lake intake, for an apportioned population of 66,767 people served by the Salem Lake intake (Ref 32). According to Officer Cary Bostic, District 7 Wildlife Enforcement Officer, Salem Lake is regularly fished by boat. People fish from the Old Greensboro Road bridge over Salem Lake, approximately 0.8 mile downstream of PPE1 (Ref 42). No fishery production data was available for Salem Lake. As previously reported, a palustrine scrub-shrub type wetland exists along the unnamed tributary that connects Basin #I to Lowery Mill Creek, for 0.25 miles of wetland frontage (Figs. 3, 4-1). The National Wetland Inventory Maps identify 1.13 miles of wetland frontage bordering Lowery Mill Creek between the confluence of the unnamed tributary and Salem Lake. Salem Lake has 0.24 miles of marshy wetland frontage at its headwaters above the Old Greensboro Road bridge. According to the National Wetland Inventory Maps, 0. 70 miles of wetland frontage borders the segments of Salem Creek between the Salem Lake dam downstream to the end of the 15 mile surface water target distance limit (Ref 43). According to the NC Natural Heritage Program, there are no occurrences of rare, threatened, or endangered plant or animal species within the 15-mile target distance limit below the site (Ref. 44). 5.3 Previous Surface Water Investigations 23 I I I I I I I I I I I I I I I I I I I On June 25, 1991, personnel from Greenhome and O'Mara sampled surface water and sediment samples from the two main tributaries that receive runoff from the site. One set was collected from the unnamed tributary that connects sedimentation Basin # 1 to Lowery Mill Creek ("SW-02" and "SED-02"), and the other set was collected from the unnamed tributary that connects sedimentation Basins #2 and #3 to Lowery Mill Creek ("SW-01" and "SED-01 "). The samples were submitted to the North Carolina State Laboratory of Public Health for purgeable and extractable organics (TCL) and inorganics (TAL) analyses (Ref 14). Compared to the surface water sample collected north of the site (SW-01), surface water sample (SW-02) exhibited elevated levels of barium (90 ug/1), and lead (1,035 ug/1) from the unnamed tributary below Basin #1 (Ref 14, p. 3). The concentration oflead found in the surface water below Basin #1 exceeds the August 1996 EPA SCDM ambient water quality criteria benchmark of3.2 ug/1 for determining chronic risk posed to aquatic organisms (Ref 27, p. B-55). Using the sediment sample collected north of the site (SED-01) as the background, the sediment sample (SED-02) exhibited elevated levels of phenanthrene (367 ug/kg), fluoranthene (2, 167 ug/kg), pyrene (1,700 ug/kg), benzo( a) anthracene (800 ug/kg), chrysene ( 1, 783 ug/kg), bis(2- ethylhexyl)phthalate (4,683 ug/kg), benzo(b)fluoranthene (1,667 ug/kg), chromium (45 mg/kg) and lead (4,700 mg/kg) from the unnamed tributary below Basin # 1. Lead was shown to leach from the same sediment sample (SED-02) at levels (144.87 mg/I) roughly 29 times greater that the RCRA regulatory levels that would classify a hazardous waste (5.0 mg/I) (Ref 14, p. 2-3). There are currently no promulgated EPA SCDM benchmarks for determining the ecological risk posed by contaminated sediments. However, the levels of lead and benzo(b )fluoranthene found in sediment would exceed the current EPA human health-based soil screening benchmark or State of North Carolina Inactive Hazardous Sites branch soil remediation goals (Ref 27, 28). 5.4 Surface Water Sample Locations During the May 1997 onsite reconnaissance, three sedimentation basins were observed that retain runoff along the west boundary of the site (Ref 4). The basins are part of a permitted stormwater management plan for the facility. The discharge from the basins enters two tributaries where it is then directed through wetlands to Lowery Mill Creek (Ref 16; Figures 3, 4-1 ). Since the facility recently dredged and rebuilt the sedimentation basins, the ESI sampling design incorporated collection of soil samples in the runoff pathway entering each basin (JC-012-SL, JC-013-SL and JC- 014-SL) and below the spillway from each basin (JC-002-SD, JC-003-SD and JC-004-SD) (Ref 15; Photos 1-4; Table 3, 6; Figure 4-1). Water samples were also collected below the spillway from Basins 1 (JC-004-SW) and 3 (JC-002-SW). No water sample was obtained below Basin #2 due to insufficient flow (Ref 15, pp. 13, 15, 19). The contaminant levels detected in soil samples from the runoff pathway entering each basin were previously discussed in Section 3. 0 of this report. The ESI sample teams collected numerous surface water and sediment samples from the unnamed tributaries leading from the site to Lowery Mill Creek, from Lowery Mill Creek and from 24 I I I I I I I I I I I I I I I I I I Salem Lake, to determine if contamination could be identified in surface water or sediments from each of the primary targets. In addition, the teams collected numerous surface water and sediment control samples as a quality control measure to evaluate whether any alternate sources may be discharging to Lowery Mill Creek between the site and the nearest fishery. Each team recorded the surface water sample locations by Global Positioning System (GPS) along with pH, temperature, conductivity and turbidity readings of each aqueous sample point and the physical characteristics of each sediment sample ( color, sheen, odor, etc ... ) in a log book dedicated to this. investigation (Ref 15, Attachment). The sample locations are described in Table 6 and marked in Figures I and 4-1. The ESI sample teams collected duplicate surface water and sediment samples from either surface water or sediment locations considered critical to the ~S score for the site to confirm the presence of any contaminants that were detected in these samples. In addition, a double volume of surface water samples was collected from the background location on Lowery Mill Creek to be used as the matrix spike and matrix spike duplicate sample by the contract laboratory. For quality control purposes, the sample investigation included two trip blanks, a field blank, a soil trip blank, a pre- . I preservative blank and a post-preservative blank to evaluate the potential for cross contamination (Ref 16, 21). There are several mixing zones between the site and the nearest fishery. Sample locations from mixing zones were chosen to collect a well-mixed representative sample. Since the site contaminants consist primarily of metals which are known to easily sorb to organic sediments, sediment samples were collected from fine, silty, dark-colored sediments containing relatively high organic contents, where possible (Ref 16, 21 ). Since surface water from Salem Lake may contain a naturally higher turbidity than surface water from Lowery Mill Creek, a background surface water and sediment sample was collected from the south wing of Salem Lake at the Old Greensboro Road brid~e for comparison (JC-021-SW/SD). The sampling technique for surface water from Salem Lake involved collection of a three-point vertical composite of the water column, using a peristaltic pump/vacuum jug arrangement (Photos 30, 32). A surface water grab sample was collected from the drinking water intake on Salem Lake (JC-020-SW) to address any potential public health concerns (Ref 16, 21; Figure I). I Table 6.

US EPA Region IV, Science and Ecosystem Support Divi~ion (SESD) validated and attached Data Qualifier Reports to the analytical results provided to the NC Superfund Section. EPA considers a contaminant "significantly above background", if detected at concentrations equal to, or greater than three times the background concentrations, or if detected in the sample, but 27 I I I I I I I I I I I I I I I I I I I not detected in the background. Routine sampling and analysis variations can introduce a degree of error into the analytical data. Data validation checks the usability:ofthe analytical data and identifies the error (bias) present. The validation process assigns qualifiers, such as "J", to biased data. For ' example, "J" qualified results indicate the sample concentratioris are estimated, but may be used to determine an observed release. Where "J" qualified results are reported, EPA guidance directs the user to determine the actual sample bias for that compound and arithmetically manipulate the sample results by a predetermined factor, if appropriate. The new results are then used to decide if the compound in question is "significantly above background". The EPA guidance on using "J" qualified data is attached as Ref 23 . Where multiple background samples were collected, the determination whether contaminants detected were "significantly above background" was based on the higher concentration of the detected contaminant in either of the background sample(s). Several TCL extractable samples were qualified as "JN", due to exceeding holding times. The holding times are designed to ensure against unacceptable losses in transit and in the laboratory that would create unreliable results and an inaccurate representation, of the original sample result. Any sample result flagged as "JN" was not used in evaluating the site score. The QNQC sample results demonstrate that no TCL or T AL analytes were introduced into the field aqueous samples during the sample preservation. Toluene was reported in the soil trip blank, at a concentration below the CRDL. Since it was also found in several sediment samples at concentrations below the CRDL, and is a possible lab artifact, toluene was not used in evaluating a release to soil or sediments at the site. The US EPA shipped spike samples to the analytical contract laboratories. The validated results did not report any problems associated with the Blind Spi,ke recoveries for aqueous samples, suggesting that the sample handling and analytical procedures performed by the laboratories were acceptable, and suggesting a strong confidence in the laboratory accuracy. A blind spike recovery problem was reported for the sodium analyte, which would affect any hits of sodium in soil and sediment samples. However, sodium was not detected at '.concentrations significantly above background in any of the soil or sediment samples. Two sets of matrix spike/matrix spike duplicate aqueous' samples were collected in the field for analyses by the contract laboratories. The validated re~ults did not report any problems associated with the matrix spike/matrix spike duplicate recoveries in the aqueous samples, providing evidence of good field sampling technique, and suggesting a strong confidence in the laboratory analytical precision for the aqueous matrix. The sediment sample handling variability was determined through analyses of split samples (JC-008-SD and JC-108-SD) collected in the field, and a statisticalicomparison of the relative percent deviation between the reported analytical results. No organic T~L compounds were reported in the two samples. The low sample variability between the two sediment samples (less than 20% relative percent deviation between 12 of the 13 inorganic T AL analytek) provides evidence of good field sampling technique, and suggests a strong confidence in the laboratory analytical precision for the ' 28 I I I I I I I I I I I I I I I I I I I sediment matrix. Only aluminum exhibited a RPO greater than 20 % (21.2 %). 5.5.2 Surface Water Pathway Analytical Results 5.5.2.1 Ihc Unnamed Tributar:y ~ Basin #I The surface water analytical results are summarized in Talile 7-1. Compared to an upgradient aqueous background sample for Basin # I (JC-00 I-SW), aqueous sample JC-004-SW exhibited I elevated concentrations of lead (22 ug/1) and manganese (270 ug/1) in the unnamed tributary (UT) below Basin #1. Further downstream in the UT, surface water sample JC-006-SW exhibited elevated concentrations oflead (5 ug/1), manganese (360 ug/1), and iron (2,600 ug/1). The surface water was collected approximately 332 feet below the head of the first wetland along the unnamed tributary below Basin #1 (Ref. 15; Fig. 4-1; Photo 22). A duplicate surface water sample (JC-106-SW) collected at the same location confirmed the presence of lead (5 1ug/l), manganese (350 ug/1), nickel (3J ug/1) and iron (2,500 ug/1) in the surface water. Iron and nickel were not attributable to the site. According to EPA guidance, manganese bioaccumulates in aquktic organisms. However, EPA has not promulgated an associated ecotoxicity factor, nor an 1ecologically-based aquatic SCDM benchmark for manganese. According to EPA guidance, lead is' highly toxic to and bioaccumulates in aquatic organisms. The concentrations oflead found in both surface water samples exceed the EPA's ecologically-based ambient water quality criteria benchm~rk of3.2 ug/1. Thus, a release ofa highly toxic and bioaccumulative substance found at concentrations above the aquatic benchmarks within a wetland constitutes a potential ecological risk that warrants further action (Ref. 27). The sediment sample analytical results are summarized in Table 7-2. Compared to an upgradient background sediment sample from the UT (JC-OOl~SD), sediment sample JC-004-SD exhibited an elevated concentration oflead (340 mg/kg) collected from the unnamed tributary below Basin # I. Further downstream in the UT, sediment sample JC-006-SD exhibited elevated concentrations of methyl ethyl ketone (89 ug/1), lead (300 mg/kg), antimony (5 J mg/kg), thallium I (6.4 J mg/kg) and iron (73,000 mg/kg). This sample was collected approximately 332 feet below the head of the first wetland (Ref. 15; Fig 4-1). There are currently no promulgated EPA ecologically- based SCDM benchmarks for making a determination of the eco,logical risk posed by contaminated sediments (Ref. 27). 5.5.2.2 Ihc Unnamed Tributar:y belfilv Basins #1,, Jl.!!.!l. #3 The surface water analytical results are summarized in Table 7-1.

Further downstream, surface water sample JC-007-SW exhibited elevated concentrations of manganese (1,700 ug/1) and iron (16,000 ug/1). This sample was collected from the unnamed tributary below Basins #2 and #3 near its confluence with Lowery Mill Creek. A duplicate surface water sample (JC- 107-SW) collected at the same location confirmed the presence of manganese (1,600 ug/1) and iron (I 5,000 ug/1). Iron is not attributable to the site. According to EPA guidance, manganese bioaccumulates in aquatic organisms. However, EPA has not promulgated an associated ecotoxicity factor, nor an ecologically-based aquatic SCDM benchmark for manganese (Ref. 27). The sediment sample analytical results are summarized in Table 7-2. Compared to an upgradient background sediment sample (JC-00 I-SD), sediment sample JC-002-SD collected from the unnamed tributary below Basin #3 exhibited elevated concentrations of selenium (3. I mg/kg), silver (3.8 mg/kg) and manganese (5,600 mg/kg). No elevated concentrations of any TCL or T AL contaminants were found _in sediment sample JC-003-SD collected from the unnamed tributary downgradient of Basin #2. Further downstream, sediment sample JC-007-SD exhibited elevated concentrations of arsenic ( 5. 9 mg/kg), antimony ( 5. I J mg/kg), total mercury (I. I mg/kg) and iron (71,000 mg/kg). This sample was collected from the unnamed tributary below Basins #2 and #3 near its confluence with Lowery Mill Creek (Ref. 15). There are currently no promulgated EPA ecologically-based SCDM benchmarks for making a determination of the ecological risk posed by contaminated sediments (Ref. 27). 5.5.2,3 Lowery Mill~ The surface water analytical results are summarized in Table 7-1. Compared to the upstream background surface water sample (JC-008-SW) collected upstream in Lowery Mill Creek, surface water sample (JC-009-SW) exhibited elevated concentrations of aluminum (230 ug/1), chromium ( 15 ug/1) and total mercury (0.34 ug/1). This sample was collected from Lowery Mill Creek, about 300 feet downstream of the confluence with the unnamed tributary below Basins #2 and #3 (Ref. 15). According to EPA guidance, chromium exhibits low bioaccumulation and moderate ecotoxicity in aquatic organisms, and has a published ecologically-based benchmark of 11 ug/1. Mercury exhibits a high bioaccumulation and ecotoxicity to aquatic organisms and has a published aquatic benchmark of0.012 ug/1. (Ref. 27). Compared to the upstream background surface water (JC-008-SW), surface water sample JC- 012-SW exhibited elevated concentrations of chromium (29 ug/1), nickel (15 J ug/1) and lead (3 J ug/1). The sample was collected from Lowery Mill Creek, about 200 feet downstream of the confluence with the unnamed tributary below Basin # I. Of the three contaminants, lead exhibits a high bioaccumulation and high ecotoxicity in aquatic organisms and has a published ecologically- based benchmark of 3.2 ug/1 (Ref. 27). The presence of a highly ecotoxic and bioaccumulative substance at concentrations below the aquatic benchmarks within a wetland suggests an attenuated ecological risk may be posed to wetland organisms. The wetland frontage subject to this attenuated ecological risk extends from sample point JC-006-SW, downstream to sample point JC-012-SW, for a total of 480 feet of frontage (0.09 miles) (Figure 4-1). 32 I I I I I I I I I I I I I I I I I I I The sediment sample analytical results are summarized in Table 7-2. Compared to the upstream sediment sample (JC-008-SD), no elevated concentrations ofTCL or TAL analytes were detected in the two sediment samples (JC-009-SD and JC-012-SD) to Lowery Mill Creek (Table 6-2; Figure 4-1; Photos 26-28). Neither of the intervening surface water or sediment control samples (JC-010-SW/SD, JC- 011-SW/SD) collected between the JC-009-SW/SD and JC-012-SW/SD sample points exhibited elevated concentrations of lead, as compared to their respective background surface water and sediment samples (JC-001-SW/SD) (Appendix B). 5,5,2,4 Salem Lake The surface water analytical results are summarized in Table 7-1. Compared to the background surface water sample (JC-021-SW) collected from the south wing of Salem Lake, surface water sample JC-018-SW exhibited an elevated concentration of zinc (40 ug/1). This sample was collected from the Old Greensboro Road bridge over the north wing of Salem Lake (Photo 32). The 3-point vertical composite of the ~urface water column could document a release to the nearest fishery and additional wetland targets. According to EPA guidance, zinc is persistent in aquatic environments, exhibits a moderately high bioaccumulation and a low ecotoxicity to aquatic organisms. Zinc also has an ecologically-based SCDM screening benchmark of 110 ug/1 for determining risks to wetlands (Ref. 27). Thus, the zinc concentrations found in the surface water sample suggest that it does not pose a serious risk to aquatic organisms in wetlands. Nonetheless, an attributable release of zinc from the site was not established during the ESI or previous SI investigations. Compared to the background surface water sample (JC-021-SW), an elevated concentration of zinc (26 ug/1) was detected in a grab sample JC-020-SW collected near the raw drinking water intake near the Salem Lake dam, about 2.1 miles downstream of the site (Ref 15; p. 3; Photo 34). According to EPA guidance, zinc is persistent in aquatic environments, exhibits a low human toxicity, and has a published human health-based drinking water reference dose screening concentration of 11 mg/L (Ref 27). Thus, zinc does not pose a serious drinking water threat to humans at the concentrations found in the surface water sample. Compared to the background sediment sample (JC-021-SD) collected from the south wing of Salem Lake, an elevated concentration of selenium (3 J mg/kg) was detected in sediment sample JC-019-SD collected about I 00 feet upstream of the Old Greensboro Road bridge over the north wing of Salem Lake (Ref 15, p. 5; Photo 33). The presence of selenium was not confirmed in sediment sample JC-018-SD at the same location. According to EPA guidance, selenium bioaccumulates in and is highly toxic to aquatic organisms. Selenium is moderately toxic to humans (Ref 27). There are currently-no promulgated EPA ecologically-based benchmarks for determining the risk posed by contaminated sediments to aquatic organisms. Therefore, the risk posed by selenium contaminated sediments to terrestrial and aquatic organisms, and humans is indeterminate. 33 I I I I I I I I I I I I I I I I I I I I Compared to the background sediment from the upgradient UT (JC-001-SD}, an elevated concentration of selenium (2.3 mg/kg) was detected in a sediment control sample (JC-014-SD) collected from a unnamed tributary that discharges to Lowery Mill Creek, about 1000 feet downstream of the unnamed tributary of Basin #I. No other elevated levels of selenium were detected in the intervening surface water or sediment control samples from the tributaries that discharge to Lowery Mill Creek between the site and Salem Lake. 5.6 Surface Water Pathway Conclusions Historic releases of barium and lead were reported in surface water samples collected from the unnamed tributary below Basin #I. The concentration of lead would exceed the current EPA ecologically-based benchmark. In addition, historic releases of phenanthrene, fluoranthene, pyrene, benzo(a)anthracene, chrysene, benzo(b )fluoranthene, bis(2-ethylhexyl)phthalate, chromium and lead were reported in sediment samples collected from the unnamed tributary below Basin# I. Lead was found to be capable of leaching from the sediment at levels roughly 29 times greater than the regulatory levels that would classify it as a hazardous waste under the RCRA program. Likewise, the lead and benzo(b )fluoranthene concentrations would exceed their respective EPA human health- based soil screening benchmark or State remediation goals (Ref 27). The current analytical results reported elevated levels of phenanthrene, fluoranthene, pyrene, benzo( a)anthracene, chrysene, benzo(b )fluoranthene, benzo( a)pyrene, indeno( I ,2,3-cd}pyrene, benzo(g,h,i)perylene and lead discharging from the site to Basin # 1, and elevated levels of lead in sediment and aqueous samples collected from the unnamed tributary below Basin #1 (Section 3.0). The most recent set of sediment samples below Basin # I also exhibited fluoranthene, pyrene and benzo(b )fluoranthene, but at concentrations too small to be considered reliably quantified. Comparing the current to the historic analytical results, it appears that many similar compounds are present in onsite soils and in the overland runoff pathway from the site, but the concentrations appear to have shown a decrease within the last 6 years. The current analytical results from source, attribution and target samples demonstrate an observed release oflead from the site to a wetland that exists along the unnamed tributary connecting Basin # 1 to Lowery Mill Creek. Elevated levels of lead have been found in onsite soil samples (JC- 006-SL & JC-007-SL}, in overland runoff samples that connect the site to the sedimentation Basin #1 (JC-014-SL}, in samples of runoff below Basin #1 (JC-004-SW/SD}, and in samples of surface water and sediment from the nearest known wetland (JC-006-SW/SD & JC-106-SW/SD). According to EPA, lead exhibits a high bioaccumulation and high ecotoxicity to aquatic organisms, and an observed release oflead has been demonstrated at levels that may pose a significant threat to the nearest wetland (Ref 27). The segment affected by this observed release extends 332 linear feet downstream from the head of the wetland, for a total of664 feet of wetland frontage (or 0.13 miles). An observed release oflead was found in a surface water sample (JC-012-SW) from Lowery Mill Creek at levels that would not exceed the ecologically-based benchmark (Ref 27). This is an observed release that would extend the affected area downstream for an additional 500 feet to the 34 I I I I I I I I I I I I I I I I I I I sample point (JC-012-SW}, for a total of700 feet of additional wetland frontage (or 0.13 miles). Zinc was detected in a surface water sample collected from the Old Greensboro Road bridge over the north wing of Salem Lake and selenium was detected in one of the two sediment samples collected about I 00 feet upstream of the Old Greensboro Road bridge. However, the sample results do not demonstrate a pattern of zinc or selenium contamination originating from the site that would affect downstream targets. More importantly though, neither zinc nor selenium pose a serious enough health threat to humans or aquatic environments at their respective concentrations to warrant federal action. Zinc was detected in a grab sample collected near the raw drinking water intake at the Salem Lake dam, about 2.1 miles downstream of the site. According to EPA, there is very little threat posed to human populations at the concentrations found in surface water. In addition, the sample results do not demonstrate a pattern of zinc contamination originating from the site that would affect downstream targets. 6.0 SOIL EXPOSURE AND AIR PATHWAYS 6.1 Physical Conditions The 75-acre site is located in a rural setting. The surrounding area is used for light commercial industry and residences along West Mountain Road and Walkerton-Guthrie Road to the east and south, and agriculture to the southwest (Ref 4; Photo 5). Johnson Controls operates an automotive battery manufacturing facility at the site. The facility consists of a large manufacturing plant, a truck maintenance building, a battery storage warehouse, an acid storage building, a wastewater pretreatment system, and offices. The site layout is presented in Figure 2. The remainder of the site is covered with asphalt parking surfaces, bare soil, grass lawn, and woods. The facility is surrounded by a chain link fence and access is controlled by a security guard (Ref 4,5; Photo 5). The site is located near the top of a small hill that slopes northwest toward Lowery Mill Creek and west toward an unnamed tributary to Lowery Mill Creek (Figs. I, 3). Surface runoff from the main facility collects in catch basins and travels through underground pipes to three splash pads at the heads of three sedimentation basins along the west boundary of the site. These three basins collect stormwater runoff from the site, allowing particulates to settle out before being discharged through a large diameter vertical overflow pipe in the dam to unnamed tributaries (Ref 4; Fig. 3; Photos 1-4). Basin #I discharges to a small unnamed intermittent tributary that directs runoff northwest to Lowery Mill Creek. Basins #2 and #3 discharge to a second unnamed intermittent tributary that directs runoff north to Lowery Mill Creek. The stormwater retention basins lie outside the fenced areas of the site (Ref 4; Figures 3, 4-1). The site is underlain by Madison Series soil complex, except on sideslopes where it is mapped 35 I I I I I I I I I I I I I I I I I I I as Pacolet Series soil. Madison soils are formed from in-place weathering of mica schist and mica gneiss. The typical Madison soil profile exhibits a 6 inch surface layer of reddish-brown fine sandy loam, followed by a 22 inch layer of red clay, a 6 inch layer of red clay loam and a 22 inch layer of mottled red and yellowish-brown, partly weathered mica gneiss and schist that crushes to a sandy clay loam. The permeability of Madison series soil is moderate and the soil is medium to strongly acid (Ref. 45). 6.2 The prevailing wind direction for the site is from the southwest (Ref. 5, figure B-3). Soil Exposure and Air Pathway Targets At the time of the ESI investigation, there were 630 workers employed at the Johnson Controls facility working within 200 feet of the onsite source areas (Ref. 4). There are no schools, day care facilities or residents on or within 200 feet of known areas of soil contamination (Figure I). The nearest school is the East Forsyth High School, located approximately 0.4 miles east of the facility. East Forsyth High School has 1,300 students and 135 employees (Ref. 4). According to the North Carolina Center for Geographic Information and Analysis (CGIA), the population estimates within specified distance rings around the site are presented below in Table 8 (Ref. 46). Table 8. Population Estimates within a 4.0 mile radius. -· »-~·-·· -. 1,...,0: ..... r-.. . -. Onsite 610 630 0-0.25 m;J, 53 683 0.25 -0.50 m;Je I 618 2 301 n SQ • I O m;1.

Wetlands within a 4.0 mile radius are identified on the National Wetland Inventory maps (Ref. 43). The nearest wetland was approximately 900 feet north-northwest of the site (Ref. 37, 38; Figures 3, 4-1 ). There are no State or Federally designated endangered or threatened species located within a 4.0 mile radius of the site. No other sensitive environments were located within a 4.0 mile radius of the site (Ref. 44). 6.3 Previous Soil and Air Sample Investigations Johnson Controls currently operates air quality control equipment under air quality permit #00725R8, issued by the Forsyth County Environmental Affairs Office. The facility operates under the "synthetic minor source" category that places maintenance and operation restrictions on the air 36 I I I I I I I I I I I I I I I I I I I quality control equipment, in order to avoid being subject to Title V of the Clean Air Act. The permit regulates lead and particulate emissions from roughly 30 point source stacks at the facility in accordance with lead-acid battery industry standards. On September 18, 1996, the facility received one violation due to visible emissions released from a failed baghouse. There are no current violations reported at the facility (Ref. 19, 20). Historic air emissions are summarized in Table 2. Historic soil samples collected at the site are discussed in Section 3.0 titled "Waste/Source Sampling". The historic soil sample results demonstrated elevated levels of arsenic, calcium and lead onsite. The facility reported that arsenic and lead are generated by the production of lead-acid batteries, and the levels of both constituents found in onsite soils exceed current published EPA human health-based soil screening benchmarks, or August 1998 State Inactive Hazardous Sites Branch soil remediation goals for residential use (Ref 27, 28). 6.4 Soil Exposure and Air Pathway Sample Locations On August 11-13, 1997, the NC Superfund Section collected 8 soil samples at or downgradient of 3 potential source areas identified at the site. The soil sample locations are described in Table 3 of Section 3.0 titled "Waste/Source Sampling" and sample locations are marked on Figures 3 and 4-1. Since surficial soil samples were collected, no air monitoring was conducted during the sampling investigation. No formal air sampling investigation was conducted during the ESI since the facility operates in compliance with its air quality permit. All ESI samples were collected by NC Superfund Section personnel in accordance with the ~ 122§ EPA Environmental Investigations Standard Operating Procedures aud Quality Assurance Manual . 6.5 Soil Sample Analytical Results The soil samples were submitted to laboratories participating in the US EPA Contract Laboratory Program (CLP) and analyzed for inorganic compounds (Target Analyte List), purgeable and extractable organics compounds (Target Compound List), as specified in the CLP Statement of Work. US EPA Special Analytical Services requested the CLP laboratory perform Toxicity Characteristic Leachate Procedure for inorganics (TCLP-Metals) per EPA Method 1311. Data was validated through the US EPA Region IV, Science and Ecosystem Support Division, and the validated data along the attached Data Qualifier Reports were provided to the NC Superfund Section. Complete copies of the validated data and Data Qualifier Reports are provided in the Appendix B of this report. Soil sample analytical results from the 3 source areas have been summarized in Table 4 of Section 3.0 titled "Waste/Source Sampling". Based on the August 1997 analytical results, elevated levels ofphenanthrene, fluoranthene, pyrene, benzo(a)anthracene, chrysene, benzo(b/k)fluoranthene, benzo(a)pyrene, indeno(l,2,3-cd)pyrene, benzo(g,h,i)perylene, carbazole, arsenic, calcium, lead, manganese, total mercury, molybdenum, potassium, sodium, strontium and zinc were detected in surficial soil samples collected from three source areas at the site. Of these contaminants, benzo( a)anthracene, benzo(b/k)fluoranthene, benzo( a)pyrene, indeno( 1,2,3-cd)pyrene, 37 I I I I I I I I I I I I I I I I I I I dibenzo(g,h,i)perylene, arsenic and lead found in the lead oxide unloading area soil samples exceed either the August 1996 EPA Superfund Chemical Data Matrix (SCDM) human health-based soil screening benchmarks, or the August 1998 North Carolina Inactive Hazardous Sites Branch soil remediation goals (NC RG's). A soil sample from the overland runoff pathway connecting the site to Basin I exhibited elevated levels of phenanthrene, fluoranthene, pyrene, benzo(a)anthracene, chrysene, benzo(b/k)fluoranthene, benzo(a)pyrene, indeno(l,2,3-cd)pyrene, benzo(g,h,i)perylene and lead. The levels of benzo(a)anthracene, benzo(b/k)fluoranthene, benzo(a)pyrene and indeno (1,2,3- cd)pyrene exceed either the August 1996 EPA Superfund Chemical Data Matrix (SCDM) human health-based soil screening benchmarks, or the August 1998 North Carolina Inactive Hazardous Sites Branch soil remediation goals (NC RG's). 6.6 Soil Exposure and Air Pathway Conclusions The analytical results from onsite soil samples demonstrate elevated levels of numerous hazardous substances remaining in soils at various locations at concentrations exceeding published human health-based screening benchmarks. There are 63 0 workers employed at the facility within 200 feet of these contaminated soils. There are no residences, schools or day care facilities within 200 feet of any of the known areas of soil contamination at the site. Although the facility reports annual fugitive emissions oflead and lead compounds, the results of the stack tests as reported during conversations with Forsyth County regulators indicate that the facility is operating within compliance ofits air quality permit limitations. Since the facility stacks are part of a process that is actively regulated under the direction of Forsyth County Department of Environmental Affairs, the stack releases are not considered CERCLA-eligible. Based on their low particulate mobility and limited volume, there is little probability of the onsite soil contaminants at the three CERCLA eligible sources being entrained to air at quantities that could affect enough air pathway receptors to warrant federal action. 7.0 SUMMARY AND CONCLUSIONS The NC Superfund Section conducted an Expanded Site Inspection of the Johnson Controls- Globe Battery Division site to determine the need for further action under CERCLA. The scope of the investigation included review of available file information, a comprehensive target survey, onsite and offsite reconnaissances (May 8, June 3, and July 30, 1997), interviewing neighbors, collecting environmental samples (August 11-13, 1997) and collecting additional non-sampling information to document Hazard Ranking System factors. Samples were collected from onsite and offsite soil, groundwater, surface water and sediments. On August 11-13, 1997, the NC Superfund Section collected soil samples from three source areas and in the overland runoff pathway from the three source areas. Compared to their appropriate background soil samples, elevated levels ofphenanthrene, fluoranthene, pyrene, benzo(a)anthracene, 38 I I I I I I I I I I I I I I I I I I I chrysene, benzo(b/k)fluoranthene, benzo(a)pyrene, indeno(l ,2,3-cd)pyrene, benzo(g,h,i)perylene, carbazole, arsenic, calcium, lead, manganese, total mercury, molybdenum, potassium, sodium, strontium and zinc were detected in surficial soil samples collected from three source areas at the site. Ofthese contaminants, benzo(a)anthracene, benzo(b/k)fluoranthene, benzo(a)pyrene, indeno(l,2,3- cd)pyrene, dibenzo(g,h,i)perylene, arsenic and lead found in the lead oxide unloading area soil samples exceed either the August 1996 EPA Superfund Chemical Data Matrix (SCDM) human health-based soil screening benchmarks, or the August 1998 North Carolina Inactive Hazardous Sites Branch soil remediation goals (NC RG's). A soil sample from the overland runoff pathway connecting the site to Basin 1 exhibited elevated levels of phenanthrene, fluoranthene, pyrene, benzo( a )anthracene, chrysene, benzo(b/k)fluoranthene, benzo(a)pyrene, indeno(l,2,3-cd)pyrene, benzo(g,h,i)perylene and lead. The levels of benzo(a)anthracene, benzo(b/k)fluoranthene, benzo(a)pyrene and indeno (1,2,3- cd)pyrene exceed either the August 1996 EPA Superfund Chemical Data Matrix (SCDM) human health-based soil screening benchmarks, or the May 1997 North Carolina Inactive Hazardous Sites Branch soil remediation goals (NC RG's). No formal air samples were collected during the ESI investigation since the site is in compliance with the restrictions ofit air quality permit. Since the facility stacks are part of a process that is actively regulated under the direction of Forsyth County Department of Environmental Affairs, the stack releases are not considered CERCLA-eligible. Based on their low particulate mobility and limited volume, there is little probability of the onsite soil contaminants at the three CERCLA sources being entrained to air at quantities that could affect enough air pathway receptors to warrant federal action. During the August 13, 1997 ESI, The NC Superfund Section personnel collected a groundwater sample from the nearest residence and an upgradient background well. Compared to the background well sample, elevated levels of barium, copper, lead, manganese and zinc were identified in the nearest residential well to the site. Of these contaminants, elevated levels of lead, manganese and zinc were also found in onsite source soil samples collected during this investigation. Fortunately, the levels of contaminants did not exceed their respective EPA Maximum Contaminant Levels, or North Carolina groundwater standards. Due to the low levels of contaminants, the site does not pose a sufficient threat to groundwater users to warrant federal action. Historic releases of barium and lead were reported in surface water samples collected from the unnamed tributary below Basin # 1. In addition, historic releases of phenanthrene, fluoranthene, pyrene, benzo(a)anthracene, chrysene, benzo(b)fluoranthene, bis(2-ethylhexyl)phthalate, chromium and lead were reported in sediment samples collected from the unnamed tributary below Basin # 1. The ESI analytical results reported elevated levels of phenanthrene, fluoranthene, pyrene, benzo( a)anthracene, chrysene, benzo(b )fluoranthene, benzo( a)pyrene, indeno( 1,2,3-cd)pyrene, benzo(g,h,i)perylene and lead discharging from the site to Basin # 1, and elevated levels of lead in sediment and aqueous samples collected from the unnamed tributary below Basin # I. The most 39 I I I I I I I I I I I I I I I I I I I recent set of sediment samples below Basin # I also exhibited fluoranthene, pyrene and benzo(b )fluoranthene, but at concentrations too small to be considered reliably quantified. Comparing the current to the historic analytical results, it appears that many similar compounds are present in onsite soils and in the overland runoff pathway from the site, but the concentrations have shown a decrease within the last 6 years. The current analytical results from source, attribution and target samples demonstrate an observed release oflead from the site to surface water collected from a wetland that exists along the unnamed tributary connecting Basin # I to Lowery Mill Creek. Elevated levels of lead have been found in onsite soil samples (JC-006-SL & JC-007-SL), in overland runoff samples that connect the site to the sedimentation Basin #1 (JC-014-SL), in samples of runoff below Basin #1 (JC-004- SW/SD), and in samples of surface water and sediment from the nearest known wetland (JC-006- SW/SD & JC-106-SW/SD). Lead exhibits a high bioaccumulation and high ecotoxicity to aquatic organisms, and an observed release of lead has been demonstrated in surface water samples at levels that pose a significant threat to the nearest wetland. The segment affected by this observed release extends 332 linear feet downstream from the head of the wetland, for a total of664 feet of wetland frontage (or 0.13 miles). An observed release oflead was found in a surface water sample (JC-012-SW) from Lowery Mill Creek at levels that would not exceed the ecologically-based benchmark. This is an observed release that would extend the affected area downstream for an additional 500 feet to the sample point (JC-012-SW), for a total of700 feet of additional wetland frontage (or 0.13 miles). Based on the analytical results, the site appears to be releasing lead to surface water at concentrations that could pose a significant threat to the nearby wetland. Based on these findings, The NC Superfund Section recommends the site for further remedial action under CERCLNSARA. 40 i/ I I I I I I I I I I I I I I I I I I I Volume I/ References 1 -18 I I I I I I I I I I I I I I I I I I I Volume II/ References 19 -34 I I I I I I I I I I I I I I I I I I I I. 2. 3. 4. 5. 6. 7. 8. 9.
