INTRODUCTION

This Phase II Environmental Site Investigation (Phase II ESI) has been conducted at the request of Chrysler LLC (Chrysler) to investigate potential impacts to soil, groundwater and other media, which could have resulted from certain Recognized Environmental Conditions (RECs) at the Chrysler Assembly Plant, located in Newark, Delaware (hereinafter referred to as the “Site”). The RECs were identified during a Phase I Environmental Site Assessment (Phase I ESA) conducted by ATC Associates Inc. (ATC) in August 2008 and documented in a report dated August 15, 2008. In this Phase I ESA report, ATC identified the following RECs that would require further assessment or investigation: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13.

The Former Paint Mix Area The MCI Tower Area The Former Drum Storage Area The Former North Tank Farm Former Tank 10 Former Tank Y Former Tanks R-1 and R-2 Former Tank 11 Former Executive Garage UST The Former Hydraulic Lifts The Wood Block Flooring The Former Water Test Pool A Soil Stockpile

The scope of the Phase II ESI was in accordance with a Site Investigation Work Plan (SIWP) prepared by ATC and dated September 10, 2008. At the request of Chrysler, the consulting firm of Leggette, Brashears & Graham, Inc. (LBG) performed the investigations at the Former Paint Mix Area, the MCI Tower Area, and the Former Tank 11. ATC performed the investigations at the remaining ten RECs. The focus of the LBG investigation was to evaluate the extent of light non-aqueous phase liquids (LNAPL) at those three RECs. LBG prepared a report, dated October 28, presenting the scope, methodology and findings of their investigation. A copy of LBG’s report is provided in Appendix A.

ATC FIELD ACTIVITIES

From September 29 through October 6, 2008, Zebra Environmental Corporation of Lynbrook, New York (Zebra), under the observation of ATC, advanced 38 soil borings throughout the 10 RECs. Soil boring locations are shown on Figures 1 through 4. Soil borings were advanced using a truck-mounted Geoprobe® direct-push drilling rig. Soil borings were advanced to 15 feet below grade at all soil boring locations, with the exception of the two borings in the Wood Block Flooring area of the Main Manufacturing Building (MMB), which were advanced to five feet below grade. Soil borings advanced through the concrete floor of the MMB were first cored with a water-lubricated corer to minimize dust generation and then advanced using the Geoprobe® rig. Continuous soil samples were collected using 2-inch diameter, 46-inch long Macro Core (MC) open samplers, which will were fitted with removable cutting shoes and clear acetate liners. Samples were screened with a photo-ionization detector (PID). Soil samples for laboratory analysis were collected using pre-cleaned, dedicated polyethylene spoons. In general, the samples were collected from the 6-inch interval exhibiting the highest PID impact. If the PID readings were at ATC ASSOCIATES INC.

background or zero, the samples were collected from the 6-inch interval exhibiting the greatest visual (staining/discoloration) or olfactory (odor) impact. If there was no visual, olfactory or PID evidence of impacts, the soil samples were collected from the 6-inch soil/water interface interval. Concrete and wood block flooring samples were chipped/chiseled, as necessary. Boring logs are provided in Appendix B. Groundwater was encountered at approximately 9.5 to 10.5 feet bgs. One-inch diameter temporary well points (TWPs) with 5-foot long screens were installed in most borings. Groundwater samples were collected utilizing a peristaltic pump and dedicated high-density polyethylene (HDPE) tubing. All drilling equipment was decontaminated with Alconox and water between boreholes. Polyethylyne tubing, acetate liners and sampling spoons were dedicated to each sampling location and were discarded after use. Upon completion of drilling, thje borings were filled to the near grade surface with the residual soil generated during the advancement of the borehole and bentonite chips, as required, to fill the borehole. The surface was repaired with a concrete patch or asphalt to match the surrounding area. No residual soil was generated that required off-site disposal. Trip and field blanks were collected for quality assurance purposes. One trip blank was collected for each field day and analyzed only for VOCs. Field (rinsate) blanks were collected one per day for each type of sampling equipment used that day (spoon or tubing). In general, field blanks were analyzed for the same parameters as the environmental samples collected that day. Soil and groundwater samples were placed in laboratory supplied containers and cooled to 4 degrees centigrade (wet ice) during shipment to the laboratory. ATC completed all chain of custody documents prior to sample shipment. Samples were submitted to Accutest Laboratories (Accutest) in Dayton, New Jersey and analyzed for TCL VOCs via Environmental Protection Agency (EPA) Method 8260; TCL SVOCs via EPA Method 8270; PP Metals via 6010B; PCBs via EPA Method 8082 (soil only); and GRO/DRO via EPA Method 8015. Specific sample analyses for each REC are described in the following sections. The analytical results were compared to the Delaware Department of Natural Resources and Environmental Control (DNREC) Uniform Risk-Based Remediation Standards (URS) and Delaware Risk-Based Corrective Action Program (DERBCAP) Risk-Based Screening Levels (RBSLs). More specifically, the soil sample analytical results were compared to DNREC URS for Non-Critical Water Resource Area Unrestricted and Restricted Use standards. The laboratory analytical results for soil and groundwater samples are summarized in Tables 1 through 18. The laboratory analytical results for field and trip blanks are summarized in Table 19. Copies of the laboratory analytical reports are provided in Appendix C.

REC BACKGROUND, SCOPE OF INVESTIGATION AND RESULTS

3.1 Former Paint Mix Area Background Prior reports indicated the presence of soil and groundwater contamination in the area of former paint mix building. A fire occurred in this area in 1980. In addition, a 7,500 gallon release of purge solvent occurred in this area. A January 10, 1986 report identified an organic substance floating on water within the excavation adjacent to the paint mix building. The material was identified as Clean Purge Solvent composed of 33% toluene, 33% xylene and 33% methyl ethyl ketone (MEK). A Final Effectiveness Report prepared in August 2007 stated that a multi-phase extraction/soil vapor extraction (MPE/SVE) system installed in this area was effective in removing product from the Paint Mix Area. However, due to the periodic detection of small amounts of free product in a few wells, it was evident that product is present just outside the area of influence of the remediation system.

Scope of Investigation and Field Observations Twenty-four soil borings were advanced in this area. Six soil samples were collected and analyzed for VOCs. Six borings were converted to monitoring wells because LNAPL was observed in the soil. A detailed description of the field methodologies is provided in the LBG report in Appendix A. Results VOCs exceeding one or more DENREC standards were detected in three soil samples. LNAPL was observed in several monitoring wells with a maximum thickness of 0.91 foot. A detailed description of the results is provided in the LBG report in Appendix A. 3.2 MCI Tower Area Background Prior reports identified the presence of soil and groundwater contamination at the MCI Tower Area, likely associated with a historic gasoline release. A MPE/SVE system was installed to address the contamination. As stated in a Final Effectiveness Report prepared in August 2007, the system was effective in removing product from all wells present in this area. Scope of Investigation and Field Observations Two soil borings were advanced in this area. One soil sample was collected and analyzed for VOCs. A detailed description of the field methodologies is provided in the LBG report in Appendix A. Results LNAPL was not observed in the soil boring. Benzene and acetone exceeding one or more DENREC standards were detected in the soil sample. A detailed description of the results is provided in the LBG report in Appendix A. 3.3 Former Drum Storage Area Background A Preliminary Assessment (PA) prepared by DNREC for the Environmental Protection Agency (EPA) dated December 1985 stated that during a 1982 inspection of the former hazardous waste accumulation area, located on the north side of the plant, poor housekeeping practices were noted. Drums were placed on long racks with no secondary containment for spills. The former drum storage area was identified by Chrysler personnel as being an asphalt-paved area approximately 200 feet long by 10-15 feet wide. Scope of Investigation and Field Observations Four borings (DS-04 through DS-07) were advanced within the former drum storage area and three borings (DS-01, DS-02 and DS-03) were advanced at estimated downgradient locations. Boring locations are shown on Figure 3. Subsurface soil in this area consisted primarily of light brown to dark brown sand with some clay. Groundwater was encountered at approximately 10 feet below grade at all boring locations. With the exception of gray/black staining and a petroleum odor in shallow soils (approximately 4 feet below grade) at DS-07, none of the borings in this area showed evidence of impacts. PID readings up to 54 parts per million (ppm) were measured in the stained soils. Soil sample DS-07 was, therefore, collected from the interval with the greatest observed impacts. Soil samples from the remaining six borings were collected from the six-inch interval above the soil/groundwater interface. All soil samples were analyzed for VOCs, SVOCs, PP Metals, and PCBs. TWPs were installed at all boring locations to facilitate the collection of groundwater samples. One groundwater sample was collected from each TWP and analyzed for VOCs, SVOCs and PP Metals.

Laboratory Analytical Results Soil and groundwater analytical results are summarized in Tables 1 and 2, respectively. VOCs, SVOCs, or PCBs were not detected above DNREC standards in any of the soil samples. Arsenic was detected in soil samples DS-01 and DS-07 at a concentration of 3.4 mg/kg. This concentration is above the DNREC URS Unrestricted Use (0.4 mg/kg) but below the Restricted Use (4 mg/kg) standard. Other metals were not detected above DNREC standards. VOCs. SVOCs, PP Metals, and PCBs were not detected above DERBCAP RBSLs. 1,2-dichloroethane was detected in groundwater sample DS-01 and chloroform was detected in groundwater samples DS-03 and DS-04 at concentrations slightly above the corresponding DNREC URS standards. However, the detected concentration of 1,2-dichloroethane (0.23 µg/l) is significantly below the RBSL of 33,000 µg/l. Bis(2-ethylhexyl)phthalate was detected in groundwater samples DS01 and DS-03 and naphthalene was detected in groundwater samples DS-06 and DS-07 at concentrations slightly above DNREC URS standards. The detected concentrations of naphthalene (2.4 µg/l and 2.6 µg/l) are significantly below the RBSL of 31,000 µg/l. 3.4 Former North Tank Farm Background The North Tank Farm was located north of the main assembly plant and to the west of the Power House. The tanks were identified as Tanks 1 through 9 and consisted of eight (8) 15,000 gallon USTs and one (1) 20,000 gallon UST. A McLaren/Hart Tank Condition Report dated November 1992 indicated that all 9 USTs in the North Tank Farm area were installed in 1956. Materials stored in these tanks included transmission fluid, engine oil, power steering break fluid, gasoline, ethylene glycol (anti-freeze), and No. 2 fuel oil. The North Tank Farm was closed in 1992. According to the McLaren/Hart Tank Condition Report, none of the tanks showed evidence of a release at the time of closure. Reportedly closure documentation for the North Tank Farm is a UST Closure Report – North Tank Farm prepared by McLaren/Hart Environmental Engineering Corporation in January 1993. Scope of Investigation and Field Observations Three borings (NTF-01 through NTF-03) were advanced within the Former North Tank Farm and two borings (NTF-04 and NTF-05) were advanced at locations estimated to be downgradient of the tank farm. Boring locations are shown on Figure 3. Subsurface soil in this area consisted primarily of light brown to black sand underlain by light brown to black clay. Groundwater was encountered at approximately 9.5 to 10 feet below grade at all boring locations. Black stained soils exhibiting a strong petroleum odor and PID readings between 80 ppm and 980 ppm were encountered at depths ranging from 4.5 to 10 feet below grade in NTF-01 through NTF-03. Strong petroleum odors and saturated soils were encountered in NTF-04 within a sandy layer at 12 feet below grade. No evidence of petroleum impacts were encountered in NTF-05. TWPs were installed at all five boring locations to facilitate the collection of groundwater samples. Based on the presence of petroleum impacts, soil samples at NTF-01 through NTF-03 were collected at the interval of highest observed impact, approximately 7.5 feet below grade. No soil samples were collected at NTF-04 and NTF-05 as these borings were advanced to assess groundwater quality only. The soil samples were analyzed for VOCs, SVOCs, PP Metals, and TPH-DRO. One groundwater sample was collected from each TWP and analyzed for VOC’s, SVOCs, and PP Metals. Laboratory Analytical Results Analytical results for soil samples are summarized in Table 3. Benzene was detected in sample NTF02 at a concentration that exceeds the DNREC URS Restricted Use standard but is below the Unrestricted Use standard. Concentrations of antimony, cadmium, copper, and zinc in NTF-03 were detected above DNREC URS Unrestricted Use standards but below Restricted Use standards. Arsenic ATC ASSOCIATES INC.

was detected in samples NTF-01 through NTF-03 at concentrations ranging from 17.6 mg/kg to 327 mg/kg. These concentrations are above both the DNREC URS Unrestricted Use (0.4 mg/kg) and Restricted Use (4 mg/kg) standards. Lead was detected in NTF-03 at a concentration of 1,580 mg/kg, which exceeds the URS and DERBCAP RBSL standards. TPH-GRO concentrations were detected at 25.9 mg/kg in NTF-01 and at 2,060 mg/kg in NTF-02. The TPH-GRO concentration of 2,060 mg/kg in NTF-02 exceeds the DERBCAP Tier 0 Action Level of 100 mg/kg. TPH-DRO concentrations were detected at 578 mg/kg in NTF-02 and at 662 mg/kg in NTF-03. These concentrations are below the DERBCAP Tier 0 Action Level of 1,000 mg/kg. SVOCs were not detected above DNREC standards. At least one VOC (benzene, chlorobenzene, ethylbenzene, xylene, acetone) and at least one SVOC were detected in groundwater samples NTF-01 through NTF-04 at concentrations above DNREC URS standards. Arsenic was detected in four of the five groundwater samples at concentrations ranging from 3.6 µg/l to 308 µg/l. The URS standard is 0.5 µg/l. 3.5 Former Tank 10 Background A 1,000 gallon No. 2 Fuel Oil tank located north of the Power House was removed in 1988. The tank identified as Tank 10, was reportedly installed in 1970 and removed from service in 1986. Scope of Investigation and Field Observations ATC advanced one boring immediately to the west of the former UST (T10-01) and one immediately to the north of the former UST (T10-02). Boring locations are shown on Figure 3. Due to the presence of utilities and transformers, no borings could be advanced directly within the former UST location. Subsurface soil in this area consisted primarily of light brown to black sand underlain by reddish brown to gray/black clay. Groundwater was encountered at approximately 10 feet below grade at both boring locations. Black stained soils exhibiting a petroleum odor and PID readings ranging from 5 ppm in T10-02 to 35 ppm in T10-01 were encountered in soils from 4 to 7 feet below grade. Soil samples were collected at the interval of highest observed impact: from 6 to 7 feet below grade at T10-01 and from 4-5 feet below grade at T10-02. TWPs were installed at both boring locations to facilitate the collection of groundwater samples. Soil samples were analyzed for TPH-DRO and groundwater samples were analyzed for VOC’s and SVOCs. Laboratory Analytical Results Soil and groundwater analytical results are summarized in Tables 5 and 6, respectively. TPH-DRO concentrations were detected in soils at 150 mg/kg in T10-01 and at 233 mg/kg in T10-02. These concentrations are below the DERBCAP Tier 0 Action Level of 1,000 mg/kg. Pentachlorophenol was detected in groundwater sample T10-02 at a concentration of 4.8 µg/l, which is above DNREC URS standard of 0.6 µg/l. No other SVOCs or VOCs were detected above DNREC URS standards. 3.6 Former Tank Y Background Tank Y was a 10,000 gallon gasoline UST, located beneath the current Body Shop Extension building. The tank was removed in February 1987, when the City of Newark installed a sanitary sewer line crossing this area. Scope of Investigation and Field Observations ATC advanced four borings (TY-02 through TY-05) in the area of the former Tank Y. One additional boring (TY-01) was advanced at a downgradient location outside the building to assess potential impacts to groundwater. Boring locations are shown on Figure 4. Subsurface soils in this area ATC ASSOCIATES INC.

consisted primarily of light brown to medium brown sand with light brown to medium brown clay. Groundwater was encountered at approximately 9.5 to 10 feet below grade at all boring locations. Gray/black stained soils were encountered at 12 feet below grade in TY-02 in saturated soils; however no odors or PID readings were detected in these soils. Soil samples were collected at TY-02 through TY-05 from the six-inch interval above the soil/groundwater interface. No soil sample was collected at TY-01 as this boring was advanced to assess groundwater quality only. Soil samples were analyzed for VOCs, SVOCs, and lead. TWPs were installed at all five boring locations to facilitate the collection of groundwater samples. One groundwater sample was collected from each TWP and analyzed for VOCs, SVOCs, and lead. Laboratory Analytical Results Soil and groundwater analytical results are summarized in Tables 7 and 8, respectively. VOCs, SVOCs, and lead were not detected in the soil samples above DNREC standards. VOCs and lead were not detected in the groundwater samples at concentrations above DNREC standards. Benzo(a)anthracene; benzo(a)pyrene; carbazole; dibenzofuran; and naphthalene were detected in TY-03 at concentrations slightly above DNREC URS standards. 3.7 Former Tanks R-1 and R-2 Background R-1 and R-2 were located under the current Body Shop Extension. The USTs sizes were 250 and 400 gallon, were of steel construction, and stored fuel oil. Reportedly both tanks were installed in the 1950s and were removed on September 19, 1988. Scope of Investigation and Field Observations ATC advanced four borings in the immediate vicinity of the former Tanks R-1 and R-2. Boring locations are shown on Figure 4. Subsurface soil in this area consisted primarily of light brown to medium brown sand with light brown to medium brow clay. Groundwater was encountered from approximately 10 to 10.5 feet below grade at all boring locations. No visual or olfactory evidence of impacts were identified and no volatile organic vapors were detected with a PID in any of these borings. Soil samples from all four borings were collected at the six-inch interval above the soil/groundwater interface and analyzed for TPH-DRO. TWPs were installed at both boring locations to facilitate the collection of groundwater samples. One groundwater sample was collected from each TWP and analyzed for VOCâ&#x20AC;&#x2122;s and SVOCs. Laboratory Analytical Results Soil and groundwater analytical results are summarized in Tables 9 and 10, respectively. TPH-DRO concentrations were detected in soil sample TR-04 at 8.31 mg/kg. This concentration is below the DERBCAP Tier 0 Action Level of 1,000 mg/kg. The VOCs bromodichloromethane and chloroform and SVOCs 1,4 dichlorobenzene, benzo(a)anthracene, and bis(2-ethylhexyl)phthalate were detected in groundwater sample TR-03 above DNREC URS standards. None of the remaining groundwater samples collected contained concentrations above DNREC URS standards.

3.8 Former Tank 11 Background Prior investigations detected the presence of soil and groundwater contamination in the area of former Tank 11 (Old Shipping Gate tank) associated with a former 2,000 gallon gasoline tank, which was located near the shipping office. The UST was removed in December 1989. A leak was discovered during the excavation. The tank was observed to be in poor condition and free product was observed in the excavation. Contaminated soil was removed in December 1990 and three monitoring wells were installed near the excavation. Between February 1991 and December 1992, approximately two 55-gallon drums of product were reportedly removed from monitoring well MW-2. Scope of Investigation and Field Observations Six soil borings were advanced in this area. Two soil samples were collected and analyzed for VOCs. Two borings were converted to monitoring wells because LNAPL was observed in the borings. A detailed description of the field methodologies is provided in the LBG report in Appendix A. Results VOCs exceeding one or more DENREC standards were detected in both soil samples. LNAPL was detected in one pre-existing monitoring well and a newly installed well with a maximum thickness of 0.63 foot. A detailed description of the results is provided in the LBG report in Appendix A. 3.9 Former Executive Garage UST Background Drawings provided by Chrysler identified the presence of a gasoline UST of unknown capacity that was formerly located at the former Executive Garage, near the northeast corner of the main assembly plant. Scope of Investigation and Field Observations Two borings (EG-01 and EG-02) were advanced to the north of the Main Manufacturing Building. A third boring (EG-03) was advanced at a presumed downgradient location to the east of the Main Manufacturing Building. Boring locations are shown on Figure 3. Subsurface soils in this area consisted primarily of gray to medium brown clay underlain by light brown sand. Groundwater was encountered at approximately 10 feet below grade at all boring locations. Light brown sandy soils exhibiting a petroleum odor and PID readings between 6.2 ppm and 25 ppm were encountered at the soil/groundwater interface in EG-01 and EG-02. No evidence of petroleum impacts were encountered at EG-03. One soil sample was collected from each boring at the six-inch interval above the soil/groundwater interface and analyzed for VOCs, lead, and TPH-GRO. TWPs were installed at all boring locations to facilitate the collection of groundwater samples. One groundwater sample was collected from each TWP and analyzed for VOCs and lead. Laboratory Analytical Results Soil and groundwater analytical results are summarized in Tables 11 and 12, respectively. No VOCs, lead, or TPH-GRO concentrations were detected in soil samples above DNREC URS Restricted Use standards or Restricted Use standards. Benzene was detected in groundwater samples EG-01 and EG-02 at concentrations of 670 µg/l and 115 µg/l, respectively. These concentrations exceed the DNREC URS of 0.4 µg/l. Lead was detected in groundwater sample EG-01 at a concentration of 52.7 µg/l, which exceeds the DNREC URS and ATC ASSOCIATES INC.

DERBCAP RBSL standard of 15 Âľg/l. 3.10 Former Hydraulic Lifts Background Eight hydraulic lifts were removed from the Main Manufacturing Building during the 1970s and 1980s. Their former locations were identified by Chrysler personnel during an ATC site visit on August 25, 2008. Scope of Investigation and Field Observations ATC advanced one boring at each former hydraulic lift location. Boring locations (HL 01 through HL08) are shown on Figure 3. Subsurface soil in this area consisted primarily of light brown to medium brown sand underlain with medium brown to gray clay. Groundwater was encountered at approximately 10 feet below grade at all boring locations. With the exception of detectable concentrations of volatile organic vapors and non-petroleum odors in shallow soils (approximately 3 to 5 feet below grade) at HL-04 and HL-06, there was no evidence of impacts from the historic use of hydraulic lifts. PID readings in shallow soils at HL-04 and HL-06 measured 14 ppm and 65 ppm, respectively. Soil samples HL-04 and HL-06 were, therefore, collected from the interval with the greatest observed impacts. One soil sample was collected from each of the remaining six borings at the six-inch interval above the soil/groundwater interface. All soil samples were and analyzed for SVOCs, PP Metals, and PCBs. TWPs were installed at four of the eight boring locations to facilitate the collection of groundwater samples. One groundwater sample was collected from each TWP and analyzed for SVOCs and PP Metals. Laboratory Analytical Results Soil and groundwater analytical results are summarized in Tables 13 and 14, respectively. Benzo(a)pyrene and dibenz(a,h)anthracene were detected in HL-06 above DNREC URS Unrestricted Use standards but below DNREC URS Restricted Use standards. None of the remaining soil samples contained concentrations of SVOCs above DNREC URS standards. Arsenic was detected in HL-01, HL-02, HL-04, HL-05, and HL-06 at concentrations ranging from 4.9 mg/kg to 23.8 mg/kg. These concentrations are above both the DNREC URS Unrestricted Use (0.4 mg/kg) and Restricted Use (4 mg/kg) standards. Arsenic was also detected in HL-08 above the DNREC Unrestricted Use standard but below the Restricted Use standard. No other metals or PCBs were detected above DNREC standards in any of the soil samples. SVOCs were not detected above their respective DNREC standards in any of the groundwater samples. Zinc was detected in groundwater samples HL-01 and HL-05 at concentrations of 2,960 mg/kg and 2,010 mg/kg, respectively. These concentrations are slightly above the DNREC standard of 2,000 mg/kg. 3.11 Wood Block Flooring Background Wood block floors over six-inch thick concrete were formerly present throughout the Main Manufacturing Building. Most of the wood block flooring was removed and replaced with concrete, but some wood flooring remains at two locations within the plant. Scope of Investigation and Field Observations ATC advanced one borings within each of the two remaining areas with wood block flooring. Boring locations (WB-01 and WB-02) are shown on Figure 3. The borings were advanced to a depth of five feet. The wood block floor is underlain by a six-inch thick concrete slab and back to dark brown sand ATC ASSOCIATES INC.

and clay. Groundwater was not encountered at either boring locations. Black stained soils exhibiting PID readings of 4.6 ppm in WB-01 to 1,406 ppm in WB-02 were encountered immediately below the concrete slab. Three samples were collected from each boring location: one sample of the wood block floor, one sample from the concrete slab, and one sample from the subsurface soil of highest observed impact. Wood, concrete, and soil samples were analyzed for PCBs. Laboratory Analytical Results The soil analytical results are summarized in Table 15. PCBs were detected in WB1-Wood, WB1Concrete, and WB2-Wood at concentrations ranging from 1.27 mg/kg to 1.79 mg/kg. 3.12 Former Water Test Pool Background A military tank water test pool was historically present near the northeast corner of the new Paint Shop and may have partially extended under the current building. The pool was lined with concrete and filled with water. Military tanks were driven through the pool to test that they were water tight. When the pool was closed, the water was pumped out and the concrete was removed. The area of the former pool is currently paved with asphalt. Scope of Investigation and Field Observations Two borings (TP-01 and TP-02) were advanced in the vicinity of the Former Water Test Pool. Boring locations are shown on Figure 2. Subsurface soil in this area consisted primarily of light brown to dark reddish brown sand. Groundwater was encountered at approximately 9.5 to 10 feet below grade. Black stained soils were encountered in boring TP-01 between 3 and 3.5 feet below grade and one soil sample was collected from this interval. The sample from TP-02 was collected at the soil/groundwater interface since no impacts were noted in this boring. The soil samples were analyzed for VOCs, TPHGRO, and TPH-DRO. TWPs were installed at both boring locations to facilitate the collection of groundwater samples. One groundwater sample was collected from each TWP and analyzed for VOCâ&#x20AC;&#x2122;s. Laboratory Analytical Results Soil and groundwater analytical results are summarized in Tables 16 and 17, respectively. TPH-DRO were detected in soil sample TP-01 at a concentration of 33.3 mg/kg. This concentration is below the DERBCAP Tier 0 Action Level of 1,000 mg/kg. No other analytes were detected above DNREC URS standards in any of the samples collected. 3.13 Soil Stockpile Background A soil stockpile is located in the northwest corner of the site. The stockpile was probably associated with a former berm around the test track. Scope of Investigation and Field Observations At the time of the field investigation (October 6, 2008), the stockpile was completely covered with vegetation, which appeared to have grown through a black tarp which may have been used to cover the stockpile. Three discrete soil samples were collected from approximately one foot below the surface of the stockpile and analyzed for VOCs. In addition, three composite soil samples were collected and analyzed for SVOCs, Metals, and PCBs. Each composite sample was a composite of discrete samples collected from five different locations within the stockpile. Sampling locations (ST-01, ST-02 and ST03) are shown on Figure 2.

Phase II Environmental Site Investigation Chrysler Newark Assembly Plant Newark, Delaware 19713

Laboratory Analytical Results The soil analytical results are summarized in Table 18. None of the soil samples contained VOCs, SVOCs, or PCBs above DNREC URS Unrestricted or Restricted Use standards. Arsenic was detected in all three samples at concentrations ranging from 4.4 mg/kg to 5.4 mg/kg. These concentrations are above both the DNREC URS Unrestricted Use (0.4 mg/kg) and Restricted Use (4 mg/kg) standards.

CONCLUSIONS

Soil and/or groundwater impacts, including LNAPL and/or contaminant concentrations exceeding one or more DENREC standard were detected at the following RECs: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12.

In general, the detected parameters appear to be consistent with Site operations, with the exception of arsenic, which was detected in soil samples collected at several RECs, with a maximum concentration of 327 mg/kg. According to DENREC, typical background soil concentrations in Delaware are 1 to10 mg/kg. Most detected concentrations were below 10 mg/kg. Arsenic was a common fertilizer and pesticide, and it is possible that the elevated levels may be due to the potential use of the site for agricultural purposes prior to the construction of the Chrysler plant in 1951. Arsenic was also used for wood treatment and various other uses.

CHRYSLER, LLC LNAPL ASSESSMENT NEWARK ASSEMBLY PLANT (SCO21) 550 SOUTH COLLEGE DRIVE NEWARK, DELAWARE DNREC FACILITY ID # 3-000186 1.0

INTRODUCTION AND BACKGROUND

Chrysler, LLC (Chrysler) retained Leggette, Brashears & Graham, Inc. (LBG) to conduct an investigation to evaluate the extent of light non-aqueous phase liquids (LNAPL) at the Newark Assembly Plant, 550 South College Drive, Newark, Delaware (Figure 1). The investigation focused on three specific areas of the Plant where historical measurements from the existing ground-water monitor well network indicated product may be present or may have been detected in the past. These areas include the Tank 11 and MCI areas to the north of the main manufacturing building (MMB) and the Paint Mix Area to the south of the MMB. 2.0 2.1

INVESTIGATION

August and September 2008 Soil Borings On August 4 to 8, and September 3 and 5, 2008, LBG observed the drilling of two

soil borings in the MCI tower area (MC1 and MC2), six borings in the Tank-11 Area (TG1 through TG6), and 24 soil borings in the Paint Mix Area (P1 through P24) by B.L. Myers Brothers (B.L. Myers) of Glenmore, Pennsylvania. The first 5 feet (ft) of each soil boring was advanced using an â&#x20AC;&#x153;air knifeâ&#x20AC;? for utility clearance and the remainder was advanced using the direct push method. Undisturbed soil columns were collected using macrocore liners. The soil borings were generally drilled to depths ranging from approximately 10 ft below grade (bg) to 20 ftbg. Geologic logs for the soil borings are included in Appendix A. The soil column from each boring was examined in the field and screened for total volatile organic compounds (VOCs) using a calibrated photoionization detector (PID). Nine soil samples were collected from the borings from the intervals with the highest PID readings or with potential signs of impacts (staining, odor, LNAPL, etc.).

2 All soil samples were collected in accordance with the Delaware Department of Natural Resources (DNREC) regulations and requirements. The soil samples were placed in laboratory supplied bottleware that was labeled with the time, date, location, and depth of sampling. The samples were then placed in an ice-filled insulated cooler and submitted under chain of custody to Lancaster Laboratories, Inc. (Lancaster) in Lancaster, Pennsylvania, where they were analyzed for VOCs. The quality assurance/quality control procedure for the investigation included the preparation of field blanks, trip blanks, and chain-of-custody forms.

All soil borings were abandoned in accordance with DNREC

requirements. 2.2

Monitor Well Installation On August 7 and 8, and September 8 and 9, 2008, LBG observed B.L. Myers redrill

eight soil borings (TG1, TG4, P2, P8, P9, P11, P12, and P16) using hollow stem augers and convert the soil borings into Monitor Wells T11MW-4, T11MW-5, and SMW-49 through SMW-54 at the locations shown on Figures 2 and 3. The monitor wells were installed at these locations because of the presence of LNAPL in the original soil borings. All downhole equipment was decontaminated by steam-cleaning prior to drilling each boring. Drill cuttings were placed in steel 55-gallon DOT-approved drums, properly sealed, labeled, and temporarily stored on-site pending off-site disposal by Newark Assembly Plant personnel. The drilling logs from the monitoring wells are included in Appendix A. B.L. Myers converted the soil borings into Monitor Wells utilizing 2-inch diameter, Schedule 40 PVC riser pipe and 20-slot well screen. The annular space around each monitor well screen was backfilled with No. 2 sand pack to approximately 1 ft above the screen. A bentonite seal, at least 1 ft in thickness, was placed on top of the gravel pack and the remaining annular space was backfilled to grade with cement grout. The monitor wells were finished with water-tight locking caps and bolt-down manholes set flush with grade. Copies of the well construction diagrams are provided in Appendix B.

3 3.0 3.1

RESULTS

Soil Review of the geologic boring logs indicate that the investigation areas are generally

underlain by a three to five foot clay and silt layer present at approximately 2 to 8 ftbg and extending to approximately 8 to 13 ftbg. The clay and silt layer is underlain by a sand layer, which extends to at least 20 ftbg (deepest depth of boring termination). LNAPL was observed in Soil Borings P2, P8, P9, P11, P12, TG1, and TG4. The extent of LNAPL as determined through visual observation of soil samples while advancing soil borings is shown on Figures 2 and 3. LBG delineated areas of LNAPL to the maximum extent possible. However, buildings in the Paint Mix area restricted access to the north and south of the investigation area. P7, located inside the former Paint Mix Building, did not appear to be saturated with product. However, due to very high vapor reading (PID >3,000) and strong odors it is assumed that product would have been encountered if the hand-augered boring had been advanced deeper than 5 ftbg. The potential accumulation of vapors inside of the building caused the advancement of P7 to be ceased. The analytical results of the nine soil samples collected during boring advancement are summarized in Table 1 and a copy of the laboratory report is provided as Appendix C. Compounds which exceed Delaware Risk-Based Corrective Action Program (DERBCAP) Risk-Based Screening Levels (RBSL) and / or Delaware Uniform Risk-based Remediation Standards (DURBRS) standards for unrestricted use in both critical and non-critical scenarios are noted on Table 1. 3.2

Fluid Levels Fluid level measurements were recorded on September 8, 2008 from the eight

monitor wells installed during the soil boring investigation, and again on October 20, 2008 during the regularly scheduled semi-annual ground-water monitoring event (Table 2). The depth to ground water in monitor wells generally ranged between 7 and 9 ft below top of casing (btoc) across the site. A maximum LNAPL thickness of 0.91 feet was measured in the newly installed P8-SMW-51 in the Paint Mix Area. A hydrograph is provided as Figure 5 to show the relative water level during fluid level measurements to better assess the significance of LNAPL thickness.

ppm

parts per million – One ppm is equivalent to one milligram per kilogram (mg/kg), or one gram per million grams. For aqueous liquids, ppm is usually taken to be equivalent to milligrams per liter (mg/l), because one liter of water has a weight very close to a kilogram. For gases or vapors, one ppm is equivalent to one microliter of gas per liter of gas.

ppb

parts per billion

Dry weight basis

Results printed under this heading have been adjusted for moisture content. This increases the analyte weight concentration to approximate the value present in a similar sample without moisture.
