INTRODUCTION 1.0

ARM Group Inc. (ARM), on behalf of EnviroAnalytics Group (EAG), has completed a Phase II Investigation of a portion of the Tradepoint Atlantic property (formerly Sparrows Point Terminal, LLC) that has been designated as Area B: Parcel B15 (the Site). Parcel B15 is comprised of 16.5 acres of the approximately 3,100-acre former steel making facility (Figure 1). The Site is bounded to the south by a former Carpenter Shop (Parcel B23), to the north by the Tin Mill Canal (Parcel B18), to the west by the Humphrey Creek Wastewater Treatment Plant (Parcel B18), and to the east by the Finishing Mills Study Area (Parcel B21, Parcel B22, and Parcel B6). Parcel B15 includes a 4,275 square foot enclosed building that is in the Brick Sheds and 4.5 acres of existing pavement and laydown areas.

The Phase II Investigation was performed in accordance with procedures outlined in the approved Phase II Investigation Work Plan – Parcel B15. This Work Plan (dated September 16, 2016) was approved by the Maryland Department of the Environment and the United States Environmental Protection Agency on October 5, 2016 in compliance with requirements pursuant to the following:

• Administrative Consent Order (ACO) between Tradepoint Atlantic (formerly Sparrows Point Terminal, LLC) and the Maryland Department of the Environment (effective September 12, 2014); and

• Settlement Agreement and Covenant Not to Sue (SA) between Tradepoint Atlantic (formerly Sparrows Point Terminal, LLC) and the United States Environmental Protection Agency (effective November 25, 2014).

Parcel B15 is part of the acreage that was removed (Carveout Area) from inclusion in the Multimedia Consent Decree between Bethlehem Steel Corporation, the United States Environmental Protection Agency (EPA), and the Maryland Department of the Environment (MDE) (effective October 8, 1997) as documented in correspondence received from EPA on September 12, 2014. Based on this agreement, EPA determined that no further investigation or corrective measures will be required under the terms of the Consent Decree for the Carveout Area. However, the SA reflects that the property within the Carveout Area will remain subject to the EPA's RCRA Corrective Action authorities.

An application to enter the Tradepoint Atlantic property into the Maryland Department of the Environment Voluntary Cleanup Program (MDE-VCP) was submitted to MDE on September 10, 2014. The property’s current and anticipated future use is Tier 3 (Industrial), and plans for the property include demolition and redevelopment over the next several years.



SITE HISTORY 1.1.

From the late 1800s until 2012, the production and manufacturing of steel was conducted at Sparrows Point. Iron and steel production operations and processes at Sparrows Point included raw material handling, coke production, sinter production, iron production, steel production, and semi-finished and finished product preparation. In 1970, Sparrows Point was the largest steel facility in the United States, producing hot and cold rolled sheets, coated materials, pipes, plates, and rod and wire. The steel making operations at Sparrows Point ceased in fall 2012.

There is limited information on historical processes that occurred within Parcel B15. To confirm the status of the buildings and observe current activity at the Site prior to Phase II Field Investigation, ARM completed a site visit on June 15, 2016. D uring this site visit, it was confirmed that the Brick Sheds occupy the northern portion of Parcel B15 covering approximately 4 acres of the total parcel area. The Brick Sheds remain standing on elevated floor slabs (trailer height) with open sides. T here were stockpiles of various metals and materials being stored in the Brick Sheds at the time of the site visit. A follow-up site visit was performed on August 26, 2016 to observe current conditions in the enclosed portion of the southern Brick Shed. At the time of this visit, the shed was vacant and being used for miscellaneous storage.

OBJECTIVES 1.2.

The objective of this Phase II Investigation was to fully characterize the nature and extent of contamination at the Site. This report includes a summary of the work performed, including the environmental setting, site investigation methods, analytical results and data usability assessment, and findings and recommendations. A summary table of the site investigation locations including the boring identification number, groundwater sample identification, and sub-slab soil gas identification number, if applicable, and the analyses performed is provided as Appendix A. A human health screening level risk analysis was prepared to identify constituents and pathways of potential concern and to evaluate the significance of any observed impacts or elevated concentrations with respect to the potential future use of the Site.

This preliminary report presents the findings and recommendations based on the non-validated data. Analytical results for soils, Parcel B15 groundwater piezometers, and soil gas have been received and are provided herein. These data are considered preliminary since validation has not been completed. Results for groundwater analyses from the Area B Groundwater Phase II Investigation Report (Revision 0) dated September 30, 2016 and the Phase II Investigation Work Plan – Finishing Mills Groundwater Investigation (Revision 1) dated July 7, 2016 have been validated and are the only validated data included in this report. The Finishing Mills Phase II Groundwater Investigation Report is pending submission to the agencies. Once all validated data (50% of the total analytical dataset) has been received, a final Phase II Report that discusses the findings of the data validation and includes applicable validation flags in data tables and figures will be submitted to the agencies.



ENVIRONMENTAL SETTING 2.0

LAND USE AND SURFACE FEATURES 2.1.

The Tradepoint Atlantic property consists of the former Sparrows Point steel mill. According to the Phase I ESA prepared by Weaver Boos dated May 19, 2014, t he property is zoned Manufacturing Heavy-Industrial Major (MH-IM). Surrounding property zoning classifications (beyond Tradepoint Atlantic) include the following: Manufacturing Light (ML); Resource Conservation (RC); Density Residential (DR); Business Roadside (BR); Business Major (BM); Business Local (BL); and Residential Office (RO). Light industrial and commercial properties are located northeast of the property and northwest of the property across Bear Creek. Residential areas of Edgemere and Fort Howard are located northeast of the property across Jones Creek and to the southeast across Old Road Bay, respectively. Residential and commercial areas of Dundalk are located northwest of the property across Bear Creek.

According to topographic maps provided by EAG, the Site is at an elevation of approximately twelve (12) feet above mean sea level (amsl). Elevations at the Site range from 10 to 18 feet across the parcel area. In the northwestern corner of the parcel, the ground slightly slopes gradually to the west from 12 to 10 feet. Across most of the Site, elevations are fairly uniform with no clear discharge location. There are two mounds located in the southwest portion of the Site which appear to sharply decrease radially. Parcel B15 includes stormwater sewer infrastructure that directs runoff to the Humphrey Creek Wastewater Treatment Plant (HCWWTP). Surface waters which are collected and treated at the HCWWTP ultimately flow through a NPDES-permitted outfall (Outfall 014), which discharges to Bear Creek.

REGIONAL GEOLOGY 2.2.

The Site is located within the Atlantic Coastal Plain Physiographic Province (Coastal Plain). The western boundary of the Coastal Plain is the “Fall Line”, which separates the Coastal Plain from the Piedmont Plateau Province. The Fall Line runs from northeast to southwest along the western boundary of the Chesapeake Bay, passing through Elkton (MD), Havre de Grace (MD), Baltimore City (MD), and Laurel (MD). The eastern boundary of the Coastal Plain is the off-shore Continental Shelf.

The unconsolidated sediments beneath the Site belong to the Talbot Formation (Pleistocene), which is then underlain by the Cretaceous formations which comprise the Potomac Group (Patapsco Formation, Arundel Formation and the Patuxent Formation). T he Potomac Group formations are comprised of unconsolidated sediments of varying thicknesses and types, which may be several hundred feet to several thousand feet thick. T hese unconsolidated formations may overly deeper Mesozoic and/or Precambrian bedrock.



SITE GEOLOGY/HYDROGEOLOGY 2.3.

Groundcover at the Site is comprised of 100% slag fill based on the approximate shoreline of the Sparrows Point Peninsula in 1916, a s shown on Figure 2 (adapted from Figure 2-20 in the Description of Current Conditions (DCC) Report prepared by Rust Environmental and Infrastructure, dated January 1998).

In general, the encountered subsurface geology included slag fill materials overlying natural soils, which included fine-grained sediments (clays and silts) and coarse grained sediments (sands). Slag fill materials were encountered at depths of up to 20 feet below the ground surface (bgs), although typical thicknesses ranged from 0 to 10 feet bgs. In several cases a perched water table was indicated by the observation of two wet intervals with a dry (or moist) clay zone between the water bearing units. Shallow groundwater was observed in soil cores from 7.8 to 19.5 feet bgs across the Site. Soil boring logs are provided in Appendix B.

Groundwater was investigated across the Site via the Area B Groundwater Investigation, Finishing Mills Groundwater Investigation, and the Phase II Investigation – Area B: Parcel B15. Three shallow hydrogeologic zone monitoring wells from the Area B Groundwater Investigation are included in this Phase II Report and two shallow zone monitoring wells are included from the Finishing Mills Groundwater Investigation. Two intermediate hydrogeologic zone monitoring wells from both the Area B Groundwater Investigation and the Finishing Mills Groundwater Investigation are included in this Parcel B15 Phase II Report. In addition to these monitoring wells, three temporary groundwater sample collection points (piezometers) were installed adjacent to the Brick Sheds to investigate shallow groundwater conditions. The locations of the groundwater sampling points are indicated on Figure 3 for shallow hydrogeologic zone samples and on Figure 4 for intermediate hydrogeologic zone samples. The permanent groundwater monitoring wells were surveyed by a Maryland-licensed surveyor; however, the piezometers were not surveyed. Supporting documentation from the surveys is included in Appendix C.

A synoptic round of groundwater level measurements was collected on October 3, 2016 from each of the permanent groundwater monitoring wells from the separate Area B Groundwater Investigation and the Finishing Mills Groundwater Investigation that are located within or adjacent to the Parcel B15 boundary. Surveyed top of casing (TOC) and ground surface elevations for all applicable locations can be found in Table 1, along with the depth to water (DTW) measurements from this date.

Based on the field measurements, a groundwater potentiometric surface map was constructed for the shallow hydrogeologic zone. The potentiometric map for shallow groundwater has been included on Figure 3. As seen on Figure 3, shallow hydrogeologic zone groundwater appears to flow from the southwest portion of the Site (groundwater elevation of 2.63 feet amsl at TM05-PZM005) to the northeast portion of the Site. Shallow groundwater elevations are relatively uniform across the central portion of the Site (highest elevation of 2.63 f eet amsl and lowest



elevation observed at 2.01 feet amsl. The lowest shallow groundwater elevation observed at the Site is along the Tin Mill Canal just outside of the B15 parcel boundary (TM07-PZM005) with an elevation of 0.49 feet amsl. As seen on Figure 4, the direction of groundwater flow in the intermediate hydrogeologic zone appears to be opposite of the flow in the shallow zone, flowing from the eastern portion of the Site (groundwater elevation of 0.68 feet amsl at SW-079-MWI) towards the western portion of the Site (groundwater elevation of 0.58 feet amsl at TM03-PZM037). Intermediate groundwater elevations appear to be relatively uniform across the Site (highest elevation of 0.68 feet amsl and lowest elevation observed as 0.54 feet amsl at TM05-PZM040).



SITE INVESTIGATION 3.0

A total of 49 soil samples (from 21 boring locations), 12 groundwater samples, and 3 sub-slab soil gas samples were collected for analysis between March 29, 2016 and September 21, 2016 as part of the Parcel B15 Phase II Investigation. This Phase II Investigation utilized methods and protocols that followed the procedures included in the Quality Assurance Project Plan (QAPP) dated April 5, 2016 approved by the agencies to support the investigation and remediation of the Tradepoint Atlantic property. Information regarding the project organization, field activities and sampling methods, sampling equipment, sample handling and management procedures, the selected laboratory and analytical methods, quality control and quality assurance procedures, investigation-derived waste (IDW) management methods, and reporting requirements are described in detail in the approved Parcel B15 Work Plan dated September 16, 2016 , and the QAPP.

All site characterization activities were conducted under the site-specific health and safety plan (HASP) provided as Appendix E of the approved Work Plan.

SAMPLE TARGET IDENTIFICATION 3.1.

Previous activities within and around the buildings and facilities located on t he Tradepoint Atlantic property may have been historical sources of environmental contamination. If present, source areas were identified as targets for sampling through a c areful review of historical documents. When a sampling target was identified, a boring was placed at or next to its location using GIS software (ArcMap Version 10.3.1).

Sampling targets included, as applicable, 1) Recognized Environmental Conditions (RECs) shown on the REC Location Map provided in Weaver Boos’ Phase I ESA, 2) additional findings (non-RECs) from the Phase I ESA which were identified as potential environmental concerns, and 3) Solid Waste Management Units (SWMUs) and Areas of Concern (AOCs) identified from the DCC Report prepared by Rust Environmental and Infrastructure. RECs, additional findings (non-RECs), and SWMUs/AOCs were not identified in previous reports for the Site.

Four (4) sets of historical drawings were also reviewed to identify potential sampling targets for the Site. These drawings included the 5000 Set (Plant Arrangement), the 5100 Set (Plant Index), the 5500 Set (Plant Sewer Lines), and a set of drawings indicating coke oven gas distribution drip leg locations. Drip legs are points throughout the distribution system where coke oven gas condensate was removed from the gas pipelines. T he condensate from the drip legs was typically discharged to drums, although it is possible some spilled out of the drums and on to the ground. There were no drip legs identified inside the boundary of Parcel B15. A summary of the specific drawings covering the Site is presented in Table 2. Sampling target locations were



identified if the historical drawings depicted industrial activities or a specific feature at a location that may have been a source of environmental contamination that potentially impacted the Site.

Based on the review of plant drawings, sampling targets were identified at the Site that included the following: Brick Sheds and Scrap Yard/Open Storage Area. A summary of the areas that were investigated, along with the applicable boring identification numbers and the analyses performed, has been provided as Appendix A.

Additional sample locations were then added to fill in large spatial gaps between proposed borings to provide complete coverage of the Site. The density of soil borings met the requirements set forth in QAPP Worksheet 17 – Sampling Design and Rationale. Parcel B15 contained a total of 8.7 acres without engineered barriers. Of the 8.7 acres containing engineered barriers, 3.3 acres is covered by the Brick Sheds (sampling covered by sub-slab soil gas), and 4.5 acres consists of roads and parking area. In accordance with the relevant sampling density requirements set forth in the Quality Assurance Project Plan (QAPP) Worksheet 17 – Sampling Design and Rationale, a minimum of 9 s oil boring locations are required in the areas without engineered barriers, and a minimum of 4 soil boring locations are required in the areas currently with engineered barriers. A total of 21 soil boring locations were completed during the field investigation.

During the completion of fieldwork, it was necessary to shift some borings from the approved locations given in the Work Plan, primarily due to access restrictions, refusal, and/or utility conflicts. Table 3 provides the identification numbers of the field adjusted borings, the rationale for field adjustment, the coordinates of the proposed and final locations, and the distance/direction of the field shifts.

SOIL INVESTIGATION 3.2.

Continuous core soil borings were advanced at 21 locations across the Site to assess the presence or absence of soil contamination, and to assess the vertical distribution of any encountered contamination (Figure 5). The continuous core soil borings were advanced to depths between 5 and 25 feet bgs using the Geoprobe® MC-7 Macrocore soil sampler (surface to 10 feet bgs) and the Geoprobe® D-22 Dual-Tube Sampler (depths >10 feet bgs). At each location, each soil core was visually inspected and screened with a hand-held Photo Ionization Detector (PID) prior to logging soil types. Soil boring logs have been included as Appendix B, and the PID calibration log has been included as Appendix D. Please note that unless otherwise indicated, all Unified Soil Classification System (USCS) group symbols provided on the attached boring logs are from visual observations, and not from laboratory testing.

One shallow sample was collected from the 0 to 1 foot depth interval, and a deeper sample was collected from the 4 t o 5 foot depth interval from each continuous core soil boring. One additional set of samples was also collected from the 9 to 10 foot depth interval if groundwater



had not been encountered; however, these samples were held by the laboratory pending the analysis of the 0 to 1 and 4 to 5 foot depth interval samples. If clean surface cover materials (such as paving or gravel) were present, the first 1 foot of fine-grained material beneath this layer was collected as the surface sample. If the PID or other field observations indicated contamination to exist at a depth greater than 5 feet bgs but less than 9 feet bgs, and was above the water table, the sample from the deeper 4 to 5 foot interval was shifted to the alternate depth interval. It should be noted that soil samples were not collected from a depth that was below the water table. Soil sampling activities were conducted in accordance with the procedures and methods referenced in Field SOP Numbers 009, 012, and 013 provided in Appendix A of the QAPP.

Down-hole soil sampling equipment was decontaminated after soil sampling had been concluded at a location, according to the procedures and methods referenced in Field SOP Number 016 provided in Appendix A of the QAPP.

Soil samples were submitted to Pace Analytical Services, Inc. (PACE), and analyzed for Target Compound List (TCL) SVOCs, TAL-Metals, Oil & Grease, TPH-DRO, TPH-GRO, hexavalent chromium, and cyanide. D uring field screening of the soil cores, any sample interval that exceeded a P ID reading of 10 ppm was also be analyzed for TCL-VOCs. A dditionally, the shallow soil samples collected across the Site from the 0-1 foot bgs interval were analyzed for PCBs. Analytical methods, sample containers, preservatives, and holding times for the sample analyses are listed in the QAPP Worksheet 19 & 30 – Sample Containers, Preservation, and Holding Times.

GROUNDWATER INVESTIGATION 3.3.

Parcel B15 is located with the study areas investigated in the Area B Groundwater Investigation and adjacent to the Finishing Mills Groundwater Investigation. Three shallow monitoring wells from the Area B Groundwater Investigation (SW-021-MWS, TM03-PZM004, and TM05-PZM005) were reviewed in this Parcel B15 Phase II Investigation. Two shallow monitoring wells from the Finishing Mills Groundwater Investigation (SW-079-MWS and TM07-PZM005) were reviewed in this Parcel B15 Phase II Investigation. Two intermediate monitoring wells from the Area B Groundwater Investigation (TM03-PZM037 and TM05-PZM040) and two intermediate monitoring wells from the Finishing Mills Groundwater Investigation (SW-079-MWI and TM07-PZM045) were reviewed for the Parcel B15 Phase II Investigation. Additionally, three temporary monitoring collection points (i.e., piezometers) were installed in the shallow hydrogeologic zone on Parcel B15 to supplement the data gathered in the area-wide groundwater studies. The soil boring locations where shallow piezometers were installed during the investigation were B15-012-PZ, B15-014-PZ, and B15-018-PZ. These piezometer locations were specifically requested by the agencies in the vicinity of the Brick Sheds to determine whether the existing buildings or associated storage may be a significant source of releases to the



groundwater. The shallow groundwater sampling locations are displayed on Figure 3. The intermediate groundwater sampling locations are displayed on Figure 4. The groundwater sample collection point construction logs have been included as Appendix F.

Groundwater sample collection point construction activities were conducted in accordance with the procedures and methods referenced in Field SOP Numbers 005, 012, 013, 014, 016, 019, and 020. Temporary piezometers were installed at each location using the Geoprobe®

DT22 Dual Tube sampling system was advanced to a depth approximately 10 feet below where groundwater was identified in the associated soil cores, the 1.25-inch inner rod string was removed, and the temporary, 1-inch PVC groundwater sample collection point was installed through the outer casing. Following the installation of each sample collection point, the 0-hour depth to water was documented and the collection point was checked for the presence of non-aqueous phase liquid (NAPL) using an oil-water interface probe in accordance with the methods referenced in Field SOP Number 019 provided in Appendix A of the QAPP.

After the installation of each temporary groundwater sample collection point, down-hole equipment was decontaminated according to the procedures and methods referenced in Field SOP Number 016 provided in Appendix A of the QAPP.

Groundwater samples were collected in accordance with methods referenced in Field SOP Number 006 provided in Appendix A of the QAPP; which employed the use of a laboratory supplied sample containers and preservatives, a peristaltic pump, dedicated polyethylene tubing, and a Y SI water quality meter with a flow-through cell. Groundwater samples submitted for analysis of TAL Metals were filtered in the field with an in-line 0.45 micron filter. The sampling and purge logs have been included in Appendix F. Calibration of the YSI meter was performed before the start of each day of the sampling event, and a calibration post-check was completed at the end of the day. Appropriate documentation of the YSI calibration has also been included in Appendix F.

Groundwater samples were submitted to PACE, and analyzed for TCL-VOCs via USEP Method 8260B, TCL-SVOCs via USEPA Methods 8270D and 8270D SIM, total petroleum hydrocarbon (TPH) diesel range organics (DRO) and gasoline range organics (GRO) via USEPA Methods 8015B and 8015D, TAL-Dissolved Metals via 6010C and 7470A, hexavalent chromium via USEPA Method 7196A, and cyanide (total) via USEPA Method 9012A. In addition, permanent groundwater monitoring wells were analyzed for TAL-Total Metals via 6010C and 7470A. Select permanent groundwater monitoring wells in both the Area B Groundwater Investigation and the Finishing Mills Groundwater Investigation were analyzed for polychlorinated biphenyls (PCBs) via USEPA Method 680. Temporary piezometers installed in Parcel B15 were analyzed for Oil & Grease via USEPA Method 1664A. Sample containers, preservatives, and holding times for the sample analyses are listed in the QAPP Worksheet 19 & 30 – Sample Containers, Preservation, and Holding Times.



SOIL GAS INVESTIGATION 3.4.

A total of three temporary vapor monitoring probes were installed at each of the locations provided on Figure 6 to collect sub-slab soil gas samples. The sub-slab soil gas samples were collected according to procedures and methods referenced in Field SOP Number 002 provided in Appendix A of the QAPP.

A core-drill was used to create a pilot-hole approximately three-inches in diameter that extended through the concrete floor to facilitate the collection of each sub-slab soil gas sample. A hand auger and/or Geoprobe® was then used to create a borehole that extended through the subgrade and into the soil to a depth of at least eight inches below the bottom of the floor slab. A six inch soil gas implant, constructed of double woven stainless steel wire screen, was then attached to an appropriate length of polyethylene tubing and lowered to the bottom of the borehole. Once the implant and tubing were installed, the tubing was capped with a three-way valve, and clean sand was added around the implant to create a permeable layer that extended at least two inches above the implant. Bentonite was then added and hydrated to create a seal above the sand pack that extended to the surface. Once installed, each sub-slab soil gas monitoring probe was allowed to equilibrate for at least 24 hours.

Leak tests were performed prior to sample collection to ensure that valid soil gas samples were collected, and to provide quantitative proof of the integrity of the surface seal. T he testing involved the introduction of a gaseous tracer compound (helium) into a shroud which covered the sampling point, and then monitoring with a hand held meter for the presence of helium in the air withdrawn from the subsurface.

While the shroud was inflated, air was purged from the monitoring point using a three-way valve and a syringe. Using the same three-way valve and a syringe, a Tedlar bag was then filled with at least 500 mL of air that was withdrawn from the monitoring point. The air inside of the Tedlar bag was then screened in the field with the meter.

As stated in Field SOP Number 002, if less than 10% of the starting concentration of the tracer gas within the shroud was observed in the Tedlar bag sample, the seal could be considered competent and sampling would continue. D uring fieldwork, the concentration of helium measured in the Tedlar bag was always significantly less than 10%, and each seal was deemed adequate to proceed.

Prior to sampling, a syringe was attached to the three-way valve and three purge volumes of air were removed. After the probe had been purged of any ambient air, an evacuated stainless steel canister (summa canisters) with a flow restrictor set for an 24-hour intake time was attached to the tubing. The soil gas sample was then collected over a period of 24 hours. At the completion of the sampling period, the valve of the summa canister was closed, and an identification tag was



attached to the canister. T he probes were then removed, the borehole filled, and the surface repaired.

Sub-slab soil gas samples were submitted to PACE, and analyzed for VOCs via USEPA Method TO-15.

MANAGEMENT OF INVESTIGATION-DERIVED WASTE (IDW) 3.5.

In accordance with Field SOP Number 005 provided in Appendix A of the QAPP, potentially impacted materials, or IDW, generated during this Phase II Investigation was containerized in 55-gallon (DOT-UN1A2) drums. T he types of IDW that was generated during this Phase II Investigation included the following:

• soil cuttings generated from soil borings or the installation of the temporary groundwater sampling points;

• purged groundwater; • decontamination fluids; and • used personal protective equipment

Following the completion of field activities, a composite sample will be gathered from the Parcel B15 Phase II IDW soil drums for TCLP analysis. A list of all results from the soil TCLP procedure will be found in Table 4, pending sample analysis.

IDW drums containing aqueous materials will be characterized by preparing composite samples from randomly selected drums. Each composite sample included aliquots from four individual drums that will be chosen from a set of 30 drums being staged on-site at the date of collection. A list of all results from the aqueous TCLP procedure will be found in Table 5, pending sample analysis. The parcel specific IDW drum log from the Phase II investigation is included as Appendix G. All IDW procedures were carried out in accordance with methods referenced in the QAPP Worksheet 21 – Field SOPs and Appendix A of the QAPP.



ANALYTICAL RESULTS 4.0

SOIL CONDITIONS 4.1.

Soil analytical results were screened against Project Action Limits (PALs) established in the site-wide Quality Assurance Project Plan (QAPP) dated April 5, 2016 t o identify any Contaminants of Potential Concern (COPCs) based on E PA’s Regional Screening Levels (RSLs) for the composite worker exposure to soil. The analytical results for the detected parameters are summarized and compared to the PALs in attached Table 6 (Organics) and Table 7 (Inorganics). The laboratory Certificates of Analysis (including Chains of Custody) are included as Appendix H. Data validation has not been completed at this time, but once validation has been completed the full Data Validation Reports will be included as Appendix I. The laboratory reports contain descriptions of the flags assigned to individual results in the attached summary tables (non-validated data).

4.1.1. Soil Conditions: Organic Compounds

As provided on Table 6, several VOCs were identified above the laboratory’s limits of detection (LODs) in the soil samples collected from across the Site. There were no VOCs detected above their respective PALs.

Table 6 provides a summary of SVOCs detected above the laboratory’s LODs in the soil samples collected from across the Site. Seven SVOCs, all polynuclear aromatic hydrocarbons (PAHs), were detected above their respective PALs. These SVOCs were benzo[a]anthracene, benzo[a]pyrene, benzo[b]fluoranthene, benzo[k]fluoranthene, dibenz[a,h]anthracene, indeno[1,2,3-c,d]pyrene, and naphthalene. Exceedances were noted at over half of the boring locations distributed throughout the parcel. A summary of the PAL exceedance locations and results has been provided on Figure S-1.

Shallow soil samples collected across the Site from the 0-1 foot bgs interval were analyzed for PCBs. Table 6 provides a summary of the PCBs detected above the laboratory’s LODs. PCB (total) was detected above its PAL in three surface soil samples (B15-007-SB-1, B15-008-SB-1, and B15-010-SB-1). A summary of the PAL exceedance locations and results have been provided on Figure S-2.

All soil samples were analyzed for Oil & Grease and TPH-DRO/GRO. There were detections of Oil & Grease at all locations that were analyzed for Oil & Grease across the Site. While no PAL was specified for Oil & Grease in the approved QAPP, Table 6 provides a summary of the detections. The table also provides a summary of TPH-DRO/GRO detections. The highest detection of Oil & Grease (24,900 mg/kg) was identified in boring B15-008-SB-9; which targeted the Scrap Yard/Open Storage Area. DRO was detected above its PAL at six sample locations. The highest detection of DRO (13,500 mg/kg) was also identified in the same sample



(B15-008-SB-9). GRO was not detected above its PAL in any sample location. A summary of the TPH/Oil & Grease PAL exceedance locations and results has been provided Figure S-3.

4.1.2. Soil Conditions: Inorganic Constituents

Table 7 provides a summary of inorganic constituents detected above the laboratory’s LODs in the soil samples collected from across the Site. Five inorganic compounds (arsenic, manganese, lead, thallium, and vanadium) were detected above their respective PALs. Arsenic was by far the most common inorganic exceedance, and was detected above the PAL in 44 (approximately 90%) of the soil samples analyzed for this compound. In comparison, manganese, lead, hexavalent chromium, thallium, and cadmium accounted for only 22 total exceedances. Vanadium only exceeded its PAL at one location (B15-007-SB-1). A summary of the inorganic PAL exceedance locations and results has been provided on Figure S-4.

4.1.3. Soil Conditions: Results Summary

Table 6 and Table 7 provide a summary of the detected organic compounds and inorganics in the soil samples from the Site, and Figures S-1 through S-4 present a summary of the soil sample results that exceeded the PALs. Any compound for which any result exceeded the PAL was identified as a COPC. Table 8 provides a summary of results for all COPCs in soil with comparisons to the respective PALs. Table 9 indicates which soil impacts (PAL exceedances) are associated with the specific targets listed in the Parcel B15 Work Plan. There were no detections of VOCs above the PAL. C OPCs in soil within Parcel B15 consisted of five inorganics (arsenic, manganese, lead, thallium, and vanadium), seven SVOCs (benzo[a]anthracene, benzo[a]pyrene, benzo[b]fluoranthene, benzo[k]fluoranthene, dibenz[a,h]anthracene, indeno[1,2,3-c,d]pyrene, and naphthalene), PCBs (total), and TPH-DRO. Arsenic was detected above the PAL in most soil samples, although only three samples had a concentration greater than 20.1 mg/kg (B15-008-SB-9 at 58.1 m g/kg, B15-018-SB-1 at 54.1 mg/kg, and B15-018-SB-6 at 33.8 m g/kg). Manganese, lead, vanadium, and thallium were detected above the PALs in a few samples each. Vanadium was only detected above the PAL in one sample (B15-007-SB-1). Thallium was detected above the PAL in nine samples in seven locations (B15-002-SB, B15-007-SB, B15-013-SB, B15-016-SB, B15-019-SB, B15-020-SB, and B15-021-SB. PCBs (total) was detected slightly above its PAL (0.97 mg/kg) in only three sample locations (B15-007-SB-1, B15-008-SB-1, and B15-010-SB-1) and the highest detection was 1.267 mg/kg. DRO was detected above its PAL in soil in only six sample locations (B15-006-SB-4, B15-008-SB-9, B15-010-SB-5, B15-015-SB-1, B15-017-SB-1, and B15-020-SB-7). The maximum detections for five of the seven PAH compounds were associated with a single sample (B15-008-SB-9) which targeted the Scrap Yard/Open Storage Area.



GROUNDWATER CONDITIONS 4.2.

The analytical results for the detected parameters in groundwater are summarized and compared to the site-specific PALs in attached Table 10 (Shallow Organics), Table 11 (Intermediate Organics), Table 12 (Shallow Inorganics), and Table 13 (Intermediate Inorganics). The laboratory Certificates of Analysis (including Chains of Custody) are included as Appendix J. Data validation has not been completed for the temporary groundwater sampling points at this time, but once validation has been completed the full Data Validation Reports will be included as Appendix K. T he laboratory reports contain descriptions of the flags assigned to individual results in the attached summary tables (non-validated data).

4.2.1. Groundwater Conditions: Organic Compounds

As provided on Table 10, few VOCs were identified above the laboratory’s limits of detection (LODs) in the shallow zone groundwater samples collected from across the Site. Tetrachloroethene was detected slightly above its PAL (6.3 μg/L compared to the 5 μg/L PAL), at a single sample location (B15-014-PZ). Chloroform was detected above its respective PAL at two locations (SW-021-MWS and TM05-PZM005). A summary of the PAL exceedance locations and results for the shallow zone has been provided as Figure GW-1. As indicated on Table 11 only chloroform was detected above its PAL in intermediate zone groundwater samples in two locations (SW-079-MWI and TM03-PZM037). A summary of the PAL exceedance locations and results for the intermediate zone has been provided as Figure GW-2.

Table 10 provides a summary of SVOCs reported in shallow zone groundwater above the laboratory’s LODs. Five SVOCs (1,1-biphenyl, benzo[a]anthracene, benzo[b]fluoranthene, indeno[1,2,3-c,d]pyrene, and naphthalene) were detected above their respective PALs. Indeno[1,2,3-c,d]pyrene and 1,1-biphenyl were only detected above their PALs at one location, (TM05-PZM005 and TM03-PZM004, respectively), with detections of 0.037 μg/L and 2.2 μg/L, respectively. The remaining groundwater COPCs were identified above the PALs in at least three locations each. A summary of the PAL exceedance locations and results for the shallow zone has been provided as Figure GW-3. As indicated on Table 11, five SVOCs (1,4-dioxane, benzo[a]anthracene, benzo[b]fluoranthene, benzo[k]fluoranthene, and naphthalene) exceeded their respective PALs in the intermediate zone samples collected from across the Site. A summary of the PAL exceedance locations and results in the intermediate zone has been provided as Figure GW-4.

As specified in the Area B Groundwater Investigation, wells located along the perimeter of the Study Area were analyzed for PCBs. As specified in the Finishing Mills Groundwater Investigation, wells located adjacent to the Tin Mill Canal were analyzed for PCBs. Piezometers installed in accordance with the Phase II Investigation – Area B: Parcel B15 Work Plan, were not analyzed for PCBs in groundwater samples. As provided on Table 10, PCBs (total) from shallow zone wells were detected above the LODs in both sample locations that required groundwater



PCB analysis (SW-021-MWS and TM07-PZM005). Trichlorobiphenyl was also detected above the LOD in sample location TM07-PZM005. As indicated on Table 11, TM07-PZM045 was the only intermediate zone sample that was analyzed for PCBs. PCBs (total) was detected above the LOD at this location. There were no PCB PAL exceedances in either shallow or intermediate zone samples across the Site.

While no PAL was specified in the approved QAPP for Oil & Grease, Table 10 provides a summary of the Oil & Grease detections in temporary piezometers sampled at the Site. The table also provides a summary of TPH-DRO detections in groundwater. The maximum detection of Oil & Grease was 3,500 μg/L (“J” flagged) at B15-018-PZ. DRO exceeded its PAL in six of the eight shallow zone sample locations. A summary of the shallow zone TPH/Oil & Grease PAL exceedance locations and results has been provided on Figure GW-5. As seen on Table 11, all intermediate zone samples exceeded the DRO PAL. A summary of the intermediate zone TPH/Oil & Grease PAL exceedance locations and results has been provided on Figure GW-6.

4.2.2. Groundwater Conditions: Inorganic Constituents

Table 12 provides a summary of shallow hydrogeologic zone inorganic constituents detected above the LODs in the groundwater samples collected from across the Site. A total of three inorganic compounds (thallium, vanadium, and hexavalent chromium) were detected above their respective PALs. Vanadium and thallium (total and dissolved) were only detected above their PALs in permanent shallow zones wells, whereas hexavalent chromium (dissolved) was only detected above its PAL in shallow temporary piezometers. Vanadium exceeded its PAL in all permanent shallow zone samples (both total and dissolved). A summary of the PAL exceedance locations and results in the shallow zone has been provided as Figure GW-7. Table 13 provides a summary of intermediate hydrogeologic zone inorganic constituents detected above the LODs in the groundwater samples collected from across the Site. Arsenic (total and dissolved), iron (total and dissolved), and manganese (total and dissolved) were the only inorganic constituents to exceed their PALs in the intermediate zone samples. A summary of the PAL exceedance locations and results in the intermediate zone has been provided as Figure GW-8.

4.2.3. Groundwater Conditions: Results Summary

Groundwater data were collected in and adjacent to Parcel B15 as part of the Area B Groundwater Investigation and the Finishing Mills Groundwater Investigation. Three shallow temporary groundwater sample collection points were specifically requested by the agencies for investigation of the Brick Sheds (and associated storage areas) to determine whether the existing buildings may be a significant source of releases to the groundwater.



The groundwater data in and around Parcel B15 was specifically evaluated to determine whether impacts observed within the parcel are consistent with the impacts addressed in the area-wide investigations, and if any of the identified groundwater impacts appear to originate from possible sources located within the parcel. Dissolved hexavalent chromium (B15-012-PZ, B15-014-PZ, and B15-018-PZ) and naphthalene (B15-014-PZ and TM03-PZM004) were reported at elevated levels in several groundwater samples. Dissolved hexavalent chromium was only reported in the three temporary groundwater sample collection points added around the Brick Sheds, and no detections of total hexavalent chromium were reported in the samples from the monitoring wells. The hexavalent chromium results are suspect because the dissolved chromium results in the same piezometer samples were lower than the reported dissolved hexavalent chromium values. Results for hexavalent chromium have commonly been impacted by sample color (matrix interferences). In the case of the maximum detection for dissolved hexavalent chromium (80 μg/L in B15-012-PZ), dissolved chromium in this sample was below the reporting limit o f 5 μg/L. Naphthalene was found in most of the groundwater samples, with the exception of the two points in the northeast corner. The highest naphthalene detection was in TM03-PZM004, located to the west of the parcel boundary. Based on the relatively low magnitude of the naphthalene detections within the parcel boundary, a significant source of naphthalene is not suspected in the parcel. Vanadium was also detected above the PAL in five of the groundwater samples, only one of which (TM05-PZM005) is located within the parcel boundaries. T here were no va nadium exceedances in the vicinity of the Brick Sheds, and the highest detection was in TM05-PZM005, which is located near the upgradient boundary of the parcel.

The presence and absence of groundwater impacts within the Site boundaries have been adequately described. The three piezometers installed to investigate possible sources related to the Brick Sheds did not appear to be more heavily impacted than the area-wide monitoring wells in the vicinity of the Site, indicating that the existing buildings are not significant sources of groundwater impacts. Based on the sporadic and relatively low-level results identified during this effort, significant potential ongoing sources of groundwater contamination have not been identified within the Site boundaries.

4.2.4. Non-Aqueous Phase Liquid

Immediately after the installation of each groundwater sampling point (B15-012-PZ, B15-014-PZ, B15-018-PZ, SW-021-MWS, SW-079-MWS, TM03-PZM004, TM03-PZM037, TM05-PZM005, TM05-PZM040, TM07-PZM005, and TM07-PZM045), an oil-water interface probe was used to check for the presence of NAPL in accordance with the methods referenced in Field SOP Number 019 provided in Appendix A of the QAPP. During the initial check, NAPL was not detected in any groundwater sampling point. Additional NAPL checks were completed 24 hours after installation, and again prior to groundwater sampling (March 29 through August 30,



2016). NAPL was not detected in any groundwater point during these checks, and no delineation activities were warranted.

During the installation of B15-003-SB, indications of potential NAPL were observed at approximately 10 feet bgs. This location targeted the Brick Sheds. A piezometer was installed on August 22, 2016 and checked for presence of product with an oil-water interface probe immediately after installation, and again 48 hours later. The piezometer was checked again after 30 days. No measureable NAPL was detected in the piezometers during any of the NAPL checks, and no additional installations were warranted following this event.

SOIL GAS CONDITIONS 4.3.

The detected VOC parameters are summarized and compared to the site-specific PALs in attached Table 14. W hile there were VOCs detected in the sub-slab samples, none of the detections exceeded the PAL for the respective compound in any of the soil gas samples submitted for analysis. The laboratory Certificates of Analysis (including Chains of Custody) are included as Appendix L. D ata validation has not been completed at this time, but once validation has been completed the full Data Validation Reports will be included as Appendix M. The laboratory reports contain descriptions of the flags assigned to individual results in the attached summary tables (non-validated data).



DATA USABILITY ASSESSMENT 5.0

The approved site-wide QAPP specified a process for evaluating data usability in the context of meeting project goals. Specifically, the goal of the Phase II Investigation is to determine if potentially hazardous substances or petroleum products (VOCs, SVOCs, PCBs, TAL metals, cyanide, Oil & Grease, or TPH-DRO/GRO) are present in Site media (soil, groundwater, and sub-slab soil gas) at concentrations that could pose an unacceptable risk to Site receptors. Individual results are compared to the Project Action Limits established in the QAPP (i.e., the most current USEPA RSLs) to identify the presence of constituents of potential concern in each environmental medium.

Quality control (QC) samples were collected during field studies to evaluate field/laboratory variability. A summary of QA/QC samples associated with this investigation has been included as Appendix N. The following QC samples were submitted for analysis to support the data validation:

• Trip Blank – at a rate of one per day in coolers with VOC samples only o Soil – VOCs only o Water – VOCs only

• Blind Field Duplicate – at a rate of one per twenty samples o Soil – VOCs, SVOCs, Metals, TPH-DRO, TPH-GRO, Oil & Grease, PCBs,

Hexavalent Chromium, and Cyanide o Water – VOCs, SVOCs, Metals, TPH-DRO, TPH-GRO, Oil & Grease,

Hexavalent Chromium, and Cyanide o Air – VOCs only

• Matrix Spike/Matrix Spike Duplicate – at a rate of one per twenty samples o Soil – VOCs, SVOCs, Metals, TPH-DRO, TPH-GRO, Oil & Grease, PCBs, and

Hexavalent Chromium o Water – VOCs, SVOCs, Metals, TPH-DRO, TPH-GRO, Oil & Grease, and

Hexavalent Chromium • Field Blank and Equipment Blank – at a rate of one per twenty samples

o Soil – VOCs, SVOCs, Metals, TPH-DRO, TPH-GRO, Oil & Grease, Hexavalent Chromium, and Cyanide

o Water – VOCs, SVOCs, Metals, TPH-DRO, TPH-GRO, Oil & Grease, Hexavalent Chromium, and Cyanide

The QC samples were collected and analyzed in accordance with the QAPP Worksheet 12 – Measurement Performance Criteria, QAPP Worksheet 20 – Field Quality Control and QAPP Worksheet 28 – Analytical Quality Control and Corrective Action.



DATA VERIFICATION 5.1.

A verification review was performed on documentation generated during sample collection and analysis. The verification included a review of field log books, field data sheets, and chain-of-custody (COC) forms to ensure that all planned samples were collected, and to ensure consistency with the field methods and decontamination procedures specified in the QAPP Worksheet 21 – Field SOPs and Appendix A of the QAPP. In addition, calibration logs were reviewed to ensure that field equipment was calibrated and/or checked once per day. The logs have been provided in Appendix D (PID calibration log) and Appendix F (YSI calibration log). The laboratory deliverables were reviewed to ensure that all records specified in the QAPP as well as necessary signatures and dates are present. Sample receipt records were reviewed to ensure that the sample condition upon receipt was noted, and any missing/broken sample containers (if any) were noted and reported according to plan. The data packages were compared to the COCs to verify that results were provided for all collected samples. The data package case narratives were reviewed to ensure that all exceptions (if any) are described.

DATA VALIDATION 5.2.

USEPA Stage 2B data validation was completed for the environmental sample analyses performed by PACE and supporting Level IV Data Package information by Environmental Data Quality Inc. (EDQI).

Sample analyses have undergone an analytical quality assurance review to ensure adherence to the required protocols. The Stage 2B review was performed as outlined in “Guide for Labeling Externally Validated Laboratory Analytical Data for Superfund Use”, EPA-540-R-08-005. Results have been validated or qualified according to general guidance provided in “USEPA National Functional Guidelines for Inorganic Superfund Data Review (ISM02.1)”, USEPA October 2013. R egion III references this guidance for validation requirements. This document specifies procedures for validating data generated for Contract Laboratory Program (CLP) analyses. The approved QAPP dated October 2, 2015 and the quality control requirements specified in the methods and associated acceptance criteria were also used to evaluate the non-CLP data.

Data Validation has not been completed for Parcel B15 data. The Data Validation Reports (DVRs) provided by EDQI will be included, pending completion, as Appendix I, Appendix K, and Appendix M.

DATA USABILITY 5.3.

The data were evaluated with respect to the quality control elements of precision, bias, representativeness, comparability, completeness and sensitivity relative to data quality indicators



and performance measurement criteria outlined in QAPP Worksheet 12 – Measurement Performance Criteria. The following discussion details deviation from the performance measurement criteria, and the impact on data quality and usability.

The measurement performance criteria of precision and bias were evaluated in the data validation process as described in the Data Validation Reports provided in Appendix I, Appendix K, and Appendix M (pending completion). Where appropriate, potential limitations in the results have been indicated through final data flags. These flags indicate whether particular data points were quantitative estimates, biased high/low, associated with blank contamination, etc. Individual data flags are provided with the results in the detection summary tables. A qualifier code glossary is included with each data validation report provided by EDQI. Particular results may have been marked with the “R” flag if the result was deemed to be unreliable and was not included in any further data evaluation. A summary of the results that were rejected during data validation will be provided on Table 15 (soil), Table 16 (groundwater), and Table 17 (soil gas), pending data validation completion. A discussion of data completeness (the proportion of valid data) is included below.

Representativeness is a measure of how accurately and precisely the data describe the Site conditions. Representativeness of the samples submitted for analysis was ensured by adherence to standard sampling techniques and protocols, as well as appropriate sample preservation prior to analysis. Sampling was conducted in accordance with the QAPP Worksheet 21 – Field SOPs and Appendix A of the QAPP. S pecific Field SOPs applicable to the assessment of representativeness include Field SOP Numbers 002, 006, 007, 008, 009, 010, 011, 017, and 024. Review of the field notes and laboratory sample receipt records indicated that collection of soil, groundwater, and sub-slab soil gas at the Site was representative, with no significant deviations from the SOPs.

Comparability describes the degree of confidence in comparing two sets of data. Comparability is maintained across multiple datasets by the use of consistent sampling and analytical methods across multiple project phases. Comparability of sample results was ensured through the use of approved standard sampling and analysis methods outlined in the QAPP. QA/QC protocols help to maintain the comparability of datasets, and in this case were assessed via blind duplicates, blank samples, and spiked samples, where applicable. No deviations from the QAPP were noted in the data set.

Sensitivity is a determination of whether the analytical methods and quantitation limits will satisfy the requirements of the project. T he laboratory reports were reviewed to verify that reporting limits met the quantitation limits for specific analytes provided in QAPP Worksheet #15 – Project Action Limits and Laboratory-Specific Detection/Quantitation Limits. In general the laboratory reporting limits met the detection and quantitation limits specified in the QAPP.



Completeness is expressed as a ratio of the number of valid data points to the total number of analytical data results. Non-usable (“R” flagged) data results were determined through the data validation process. The approved QAPP specifies that the completeness of data is assessed by professional judgement, but should be greater than or equal to 90%. Data completeness for each compound will be evaluated following the receipt of the validated results. R esults from the completeness evaluation will be provided in Appendix O. The Parcel B15 Work Plan dated September 16, 2016 s pecifies that 50% of the complete soil sample analytical dataset will undergo data validation, therefore, only the samples which are submitted for validation will be included in the evaluation and discussion of data completeness.



HUMAN HEALTH SCREENING LEVEL RISK ANALYSIS (SLRA) 6.0

ANALYSIS PROCESS 6.1.

A human health Screening Level Risk Analysis (SLRA) has been conducted for soils to further evaluate the Site conditions in support of the design of necessary response measures. The SLRA included the following evaluation process:

Identification of Constituents of Potential Concern (COPCs): Analytical results for the parcel soils were compared to the Project Action Limits (PALs), which are the USEPA Industrial Soil Regional Screening Levels (RSLs). Compounds that are present at concentrations at or above the PAL were identified as COPCs to be included in the SLRA. Identification of Exposure Units (EUs): a single exposure unit including the entire area to be developed was identified for Parcel B15. Exposure Point Concentrations (EPCs): The COPC soil data for the exposure unit was divided into surface (0-1 ft) and subsurface (>1 ft) depths for estimation of potential exposure point concentrations. Thus, for the Development Area of Parcel B15 there are two soil data sets. A statistical analysis was performed for each COPC data set, using the ProUCL software (version 5.0) developed by the USEPA to determine representative reasonable maximum exposure (RME) values for the EPC for each constituent. T he RME value is typically the 95% Upper Confidence Limit (UCL) of the mean. For lead, the arithmetic mean for each depth was calculated for comparison to the Adult Lead Model-based values. For PCBs, all results equaling or exceeding 50 mg/kg would be delineated for excavation and removal (if applicable). A ll PCB results less than 50 mg/kg are included in the EPCs and risk ratio calculations. Risk Ratios: The surface soil EPCs were compared to the USEPA RSLs for the Composite Industrial Worker, and the subsurface soil EPCs were compared to the Calculator-based RSLs for Construction Worker, Soil – Other Construction Activities to develop risk ratios for each COPC. The risk ratios were calculated with a cancer risk of 1E-6 and a non-cancer Hazard Quotient (HQ) of 1. The risk ratios for the carcinogens were summed to develop a s creening level estimate of the baseline cumulative cancer risk. T he risk ratios for the non-carcinogens were segregated and summed by target organ to develop a screening level estimate of the baseline cumulative non-cancer risk. Assessment of Lead: For lead, the arithmetic mean concentrations for surface soil and subsurface soils for the site-wide EU were compared to the applicable RSL (800 mg/kg) as an initial screening. If the mean concentrations for the EU were below the applicable



RSL, the EU was identified as requiring no further action for lead. If a mean concentration exceeded the RSL, the mean values were compared to a soil lead concentration of 1,235 mg/kg, which is the most conservative (i.e., lowest) concentration calculated by the Adult Lead Model (ALM Version date 6/21/2009) that would yield a probability of 5% of a blood lead concentration of 10 u g/dL. If the arithmetic mean concentrations for the EU were below 1,235 mg/kg, the EU was identified as requiring no further action for lead. The lead averages are presented for surface and subsurface soils in Table 18. Assessment of TPH-DRO: EPCs were not calculated for TPH-DRO. Instead, the individual results were compared to the PAL set to a HQ of 1 (6,200 mg/kg). Risk Characterization Approach: For the site-wide EU, if the baseline risk ratio for each non-carcinogenic COPC does not exceed 1 (with the exception of lead), and the sum of the risk ratios for the carcinogenic COPCs does not exceed a cumulative cancer risk of less than 1E-5, then a no further action determination will be recommended.

If the baseline estimate of cumulative cancer risk exceeds 1E-5, but is less than 1E-4, then capping of the EU will be considered to be an acceptable remedy. The efficacy of capping for elevated non-cancer hazard will be evaluated in terms of the magnitude of exceedance and other factors such as bioavailability of the COPC. Similarly, for lead, if the results of the ALM indicate that the mean concentrations would present a 5% to 10% probability of a blood concentration of 10 u g/dL for the EU, then capping of the EU would be an acceptable presumptive remedy. T he mean soil lead concentrations corresponding to ALM probabilities of 5% and 10% are 1,235 mg/kg, and 2,000 mg/kg, respectively. If capping of the identified area is not proposed, additional more detailed quantitative evaluation of risk will be required for the EU.

If the sum of the risk ratios for carcinogens exceeds a cumulative cancer risk of 1E-4, further analysis of site conditions will be required including the consideration of toxicity reduction in any proposal for a remedy. The magnitude of non-carcinogen hazard exceedances and bioavailability of the COPC will also dictate further analysis of site conditions including consideration of toxicity reduction in any proposal for a remedy. In addition, if the ALM indicates that the mean concentrations would present a >10% probability of a blood concentration of 10 ug /dL for the EU, further analysis of site conditions including toxicity reduction will be completed such that the probability would be reduced to less than 10% after toxicity reduction, but before capping.



PARCEL B15 SLRA RESULTS 6.2.

ProUCL output tables (with computed UCLs and average lead values) derived from the data for each COPC in soils are provided as electronic attachments (Appendix P), with computations presented and EPCs calculated for COPCs within each of the two data sets (surface and subsurface) for the exposure unit. T he ProUCL input tables are also included as electronic attachments. T he results were evaluated to identify any samples that may require additional assessment or special management based on the risk characterization approach. The calculated EPCs are shown in Table 19 (surface soils) and Table 20 (subsurface soils). The average lead concentrations are presented for each depth in Table 18.

Risk ratios for the estimates of potential EPCs for surface and subsurface soils are shown in Table 21 and Table 22, respectively. F or the Construction Worker scenario, the parameters selected for each activity (excavating, dozing, grading, etc.) as input into the RSL Calculator are indicated on Table22.

The risk ratios indicate that the cumulative cancer risks are greater than 1E-5 but less than 1E-4 for both the Composite Worker scenario (surface soils) and the Construction Worker Scenario (subsurface soils) in the parcel-wide exposure unit. PAHs and arsenic concentrations in a few samples were the primary contributors to the cancer risk ratio for the composite worker scenario. Manganese, thallium, and vanadium were the only compounds that contributed significantly to non-cancer hazard for the Composite Worker scenario. The highest individual non-cancer HQ for the Composite Worker scenario was 4 for thallium, and when the non-cancer risks were segregated and summed by target organ for cumulative Hazard Index (HI), thallium (no target organ specified) was responsible for the highest value (4). For Construction Worker exposure to subsurface soils in the parcel, the highest HQ was 3 for manganese, which contributed to a cumulative HI of 3 for the nervous system. As with surface soils, thallium and vanadium were the other main contributors to non-cancer hazard.

None of the detections of PCBs exceeded the criterion of 50 mg/kg.

Based on an analysis of the TPH analytical results, one location exceeded the acceptable DRO level for no further action (6,200 mg/kg). The subsurface location B15-008-SB-9 targeted an open storage area and former scrap yard. T he elevated DRO detection (13,500 mg/kg) was present in the subsurface soil sample. Since the shallow soil sample at the same boring location was not impacted by elevated DRO (86.5 mg/kg at B15-008-SB-1), the soil impacts detected at 9 feet bgs may be related to migration in groundwater at the top of the water table.

As indicated on Table 18, neither surface nor subsurface soils exceeded an average lead value of 800 mg/kg.



FINDINGS AND RECOMMENDATIONS 7.0

The objective of this Phase II Investigation was to fully characterize the nature and extent of contamination at the Site. During the Phase II Investigation, a total of 12 groundwater samples, 49 soil samples (all locations/depths), and 3 s ub-slab soil gas samples were collected and analyzed to define the nature and extent of contamination in Parcel B15. The sampling and analysis plan for the parcel was developed to target specific features which represented a potential release of hazardous substances and/or petroleum products to the environment. Groundwater samples were analyzed for TCL-VOCs, TCL-SVOCs, TAL-Dissolved Metals, hexavalent chromium, and cyanide. Additionally, select permanent monitoring wells were analyzed for PCBs, whereas, the temporary piezometers were analyzed for Oil & Grease. All permanent monitoring wells were also analyzed for TAL-Total Metals. Soil samples were analyzed for TCL-VOCs, TCL-SVOCs, Oil & Grease, TAL-Metals, hexavalent chromium, and cyanide. Shallow soil samples (0-1 foot bgs) were analyzed for PCBs. Sub-slab soil gas samples were analyzed for TCL-VOCs.

The review of previous reports and historical steel plant drawings identified several targets which represented potential releases to the environment, warranting the extensive field investigations conducted during this Phase II Investigation. The samples collected during this study have provided analytical data regarding current conditions at the Site, and facilitated the identification of potential contaminant releases. S oil, groundwater, and sub-slab soil gas conditions have been adequately characterized to support risk assessment and associated response action planning, if necessary, as well as development planning.

SOIL 7.1.

The concentrations of constituents in the soil have been characterized by the Phase II Investigation and provide estimates of exposure point concentrations to support risk assessment.

Lead and PCB concentrations are well below the levels that would warrant evaluation of a removal remedy.

The risk ratios indicate that the cumulative cancer risks are greater than 1E-5 but less than 1E-4 for both the Composite Worker scenario (surface soils) and the Construction Worker Scenario (subsurface soils) in the parcel-wide exposure unit. The highest individual non-cancer HQ for the Composite Worker scenario was 4 for thallium, and when the non-cancer risks were segregated and summed by target organ for cumulative Hazard Index (HI), thallium (no target organ specified) was responsible for the highest value (4). For Construction Worker exposure to subsurface soils in the parcel, the highest HQ was 3 for manganese, which contributed to a cumulative HI of 3 for the nervous system. The cumulative cancer risk and the non-cancer hazard exceed the acceptable levels for no action. Since the estimate of cumulative cancer risk is



less than 1E-4, capping would be an appropriate remedy to address potential composite worker exposure to surface soil. If capping is not planned, further delineation of impacts to support a more detailed evaluation of risk would be warranted. The presence of elevated metals should be addressed within contractor-specific health and safety plans to address potential risk to construction workers.

The elevated DRO detection at B15-008-SB-9 (13,500 mg/kg) warrants evaluation of utility corridors to determine whether excavation and removal may be appropriate. Since the shallow soil sample at the same boring location was not impacted by elevated DRO (86.5 mg/kg at B15-008-SB-1), the soil impacts detected at 9 feet bgs may be related to migration in groundwater at the top of the water table. The elevated DRO detection at B15-008-SB should be investigated via the installation of a temporary screening piezometer. If it is determined that free petroleum product (NAPL) is present, the extent of the product should be delineated and evaluated further.

GROUNDWATER 7.2.

The presence and absence of groundwater impacts within Parcel B15 have been adequately described. Several locations were observed to be impacted by elevated levels of VOCs, SVOCs, TPH, and/or inorganics above the PALs; however, the detected levels of compounds did not suggest that sources of continuing releases of contaminant mass to the groundwater are present. The three piezometers installed to investigate possible sources related to the Brick Sheds did not appear to be more heavily impacted than the permanent monitoring wells in the vicinity of the Site, indicating that the existing buildings are not significant sources. General groundwater conditions (not parcel specific) covered by the Area B Groundwater Investigation and Finishing Mills Groundwater Investigation will be discussed further in the associated Phase II reports, but no further analysis or remedial action is recommended with regard to the potential for groundwater impacts within the Parcel B15 area.

SUB-SLAB SOIL GAS 7.3.

The nature and extent of constituents in sub-slab soil gas have been adequately characterized by the Phase II Investigation. The sub-slab samples collected during the investigation of the Brick Sheds did not contain any VOC compounds that exceeded their specified PALs. Further investigation is not recommended based on t he documentation of minimal impacts below the building slab, and the apparent insignificant risk for vapor intrusion.
