1.0 INTRODUCTION

1.1 Background and History Tecumseh Redevelopment Inc. (Tecumseh) owns approximately 1,100-acres of land

located on the west side of New York State Route 5 (Hamburg Turnpike) in the City of Lackawanna, NY (see Figures 1 and 2). Most of Tecumseh’s property is in the City of Lackawanna (the City), with portions of the property extending into the Town of Hamburg. Tecumseh’s property is bordered by NY State Route 5 on the east; Lake Erie to the west and northwest; and other industrial properties to the south and the northeast.

The property was formerly used to produce steel, coke, and related products by Bethlehem Steel Corporation (BSC). Steel production on the property was discontinued in 1983 and the coke ovens ceased activity in 2000. Tecumseh acquired its Lackawanna property from BSC’s bankruptcy estate in 2003.

A Resource Conservation and Recovery Act (RCRA) Facility Investigation (RFI) of all Solid Waste Management Units (SWMUs) located on the 1,100-acre property was initiated by BSC under an Administrative Order issued by the United States Environmental Protection Agency (USEPA) in 1990. Tecumseh completed the RFI in January 2005 (Ref. 1). USEPA subsequently determined that the Site investigation requirements of the 1990 Administrative Order were satisfied, and Tecumseh’s obligations under the 1990 Administrative Order were terminated. Tecumseh entered into an Order on Consent with the New York State Department of Environmental Conservation (NYSDEC) to undertake corrective measures at certain solid waste management units (SWMUs) primarily on the western slag fill and coke manufacturing portion of the property. As indicated on Figure 2, the CMS area encompasses approximately 500 acres.

Outside of the CMS Area, Tecumseh designated five groups of parcels for redevelopment under the New York State Brownfield Cleanup Program (BCP). These include the Phase I, IA, II, and III Business Parks, which are at various points of investigation and cleanup under the BCP and are slated for or undergoing commercial/industrial redevelopment; and the Steel Winds Site, which was remediated under the BCP and redeveloped as a commercial wind farm.

The 12.31-acre Phase IA Business Park, which is the subject of this Remedial Investigation and Alternatives Analysis (RI/AA) Report, formerly supported BSC’s steel-

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 2

making operations as detailed in Section 2.0; however, there are no SWMUs present on the Site. Remedial Investigation activities on the Phase IA Business Park were initiated in June 2010 and continued through the end of July 2010.

1.2 Purpose and Scope This RI/AA Report has been prepared on behalf of Tecumseh to present RI findings,

2.0 SITE DESCRIPTION The Phase IA Business Park is a 12.31-acre parcel located along Route 5, west of the

Phase I Business Park; and north, south, and east of lands currently owned by Gateway Trade Center (see Figures 1 and 2).

The Phase IA Business Park formerly supported BSC’s steel-making operations; however, there are no SWMUs present on the Site. Existing buildings and former operations located on the Site are shown on Figure 2. The existing structures within the Phase IA Business Park boundaries were used for the following purposes:

Blowing Engine House No. 3 was used as a repair facility for locomotives and other motor-driven vehicles employed on the site.

Boiler House No. 3/Steam Station No. 1 supplied steam for plant process equipment and instrumentation.

Power House No. 1 served as a power generation station, incorporating steam-driven turbines, transformers, and other electrical equipment to provide nearly all power required at the BSC site. Historical plant schematics indicate that a 19,900-gallon fuel oil tank may have been present to the south of Power House No. 1. The basement of the Power House also had an oil & electric room located in the southern portion of the building.

Pumping Station No. 1 supplied Lake water for use in production activities. This building was demolished in 2008 with the foundation remaining in place.

Overhead Coke Oven Gas and Other Aboveground Pipelines remain across a small portion the southwest corner of the Site. Based on previous work conducted in the Corrective Measures Study (CMS) Area (SWMU P-76) and BCP Phase II and III sites, the coke oven gas lines are known to contain hazardous constituents (naphthalene and benzene) in the condensate residuals. These overhead lines are former appurtenances of the coke over operations and are to be decontaminated and removed under a separate Order on Consent between Tecumseh and NYSDEC addressing implementation of RCRA corrective measures and are not considered part of the BCP Site.

North Return Water Trench (NRWT) is a man-made drainage channel along the eastern boundary of the Phase IA Business Park. The NRWT begins near former Pumping Station No. 1 and flows north to the Union Ship Canal via an open channel and culverts. Historically, the trench collected treated wastewater and non-contact cooling water from BSC operations. This trench will not be addressed under the BCP as it is specifically to be addressed under the RCRA Corrective Measures Order. The portion of the NRWT that flows through the Phase IA Site

Page 11: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 4

extends along the eastern side of Site Highway 7 from the southern end of the Boiler House northward to the property line, the majority of which is enclosed. Appendix A-1 includes the results of the CMS sampling of the NRWT that occurred within this stretch.

South Return Water Trench (SRWT) is a man-made drainage channel along the southern half of the Phase IA Business Park then continues flowing south across the CMS Area on Tecumseh lands to Smokes Creek. This trench will not be addressed under the BCP as it is specifically to be addressed under the RCRA Corrective Measures Order. The portion of the SRWT that flows through the Phase IA BP Site extends along the eastern side of Site Highway 7 from the northern end of the Blowing Engine House south to Times Square (see Figure 2). Appendix A-1 includes the results of the CMS sampling of the SRWT that occurred within this stretch.

2.1 Site Topography and Drainage The Phase IA Business Park is generally characterized as flat covered by sparse brush

and low-lying vegetation. The land surface is sparsely vegetated with voluntary indigenous shrubs, grasses, weeds, and emergent trees.

The United States Geological Survey Buffalo (SW), New York Quadrangle indicates that the surrounding area slopes gradually to the west toward Lake Erie (see Figure 1). Due to the granular nature of the slag/soil fill there is very little ponded stormwater or runoff as most of the precipitation seeps into the highly permeable slag/soil fill.

2.2 Remaining Site Structures As previously stated, the 12.31-acre Site and surrounding property is composed of

vacant land and three remaining buildings: the Blowing Engine House, the Boiler House, and the Power House that are remnants of the historical steel-making operations as shown on Figure 2.

2.3 Site Geology and Hydrogeology The United States Department of Agriculture Soil Survey of Erie County, New York

indicates that the Site is covered by surface soil classified as Urban Land; soil consisting of paved, foreign, or disturbed soils. Drilling logs from monitoring wells constructed on or near the Site indicate that the upper eight feet is typically composed of steel and iron-making slag, cinders, sand, and/or fill material. The fill is underlain by a peat layer and lacustrine clays and

Page 12: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 5

silts that are, in turn, underlain by shale or limestone bedrock. Bedrock is estimated to be present at approximately 60 feet below grade.

Historically, due to the proximity of Lake Erie and municipal supplied water, groundwater in the area has not been developed for industrial, agricultural, or public supply purposes. There is a deed restriction that prohibits the use of groundwater on the property. Consequently, no groundwater supply wells are present on the 1,100-acre Tecumseh property.

The groundwater isopotential map completed during the RI for the February 2011 sampling event indicates that shallow groundwater flows radially west and southwest across the Site towards the Gateway Metroport Ship Canal with a small component flowing northwest toward the Buffalo Outer Harbor. Measurements taken in Site monitoring wells indicate that the water table is generally 6 to 10 feet below ground surface (fbgs) within the soil/slag-fill unit. These flow directions and depths to the water table were confirmed during the May 2014 and February 2016 groundwater sampling events. Figures 4A and 4B are the isopotential maps for the 2011 and 2016 monitoring events.

2.4 Utilities The following utilities are present on or near the Site:

Electric Utility: Overhead electric power lines on wooden utility poles, owned by Niagara Mohawk Power Corporation (NMPC), run north and south adjacent to the Site. The electric utilities are located just east of the Site boundary and along the former Power House No. 1 (see Figure 2) but are not located within the Site boundary. The former Power House No. 1 is part of the Site.

Water: Erie County currently supplies potable water to the site. Lake Erie is not accessible from the Site without accessing other areas of the Tecumseh property or Gateway Trade Center.

Sanitary Sewers: Abandoned sewer lines are located within the Site boundaries and their exact locations and conditions are unknown. There are no plans for these utilities in the event they are destroyed during investigation activities.

2.5 Wetlands and Floodplains No State/Federal wetlands or floodplains exist at the Site.

2.6 Previous Investigations In April 2007, TurnKey Environmental Restoration, LLC (TurnKey) field personnel

collected three surface (0-2”) soil samples, identified as BP1A-SS-01 through BP1A-SS-03 (see Figure 3), for analysis of base-neutral semi-volatile organic compounds (SVOCs), PCBs, and RCRA-regulated metals. The analytical results indicate concentrations of certain PAHs (primarily naphthalene at 1,500 mg/kg in sample BP1A-SS-03) and metals (arsenic at 54.6 mg/kg and barium at 6,630 mg/kg in sample BPA1A-SS-02) above NYSDEC Part 375 commercial soil cleanup objectives (CSCOs). PCBs were also detected at low concentrations (0.17-0.37 mg/kg) in these surface soil samples, well below the CSCO of 1 mg/kg. Table 1 summarizes the analytical data from the April 2007 sampling event and Appendix A-2 includes the analytical data package.

In August 2007, Watts Architecture & Engineering, P.C. (Watts) conducted a pre-demolition asbestos abatement project for Tecumseh prior to entry of the Phase IA Business Park into the BCP. Watts provided project monitoring and air sampling/analysis services. AAA Environmental, Inc. performed asbestos abatement. Benchmark Environmental Engineering & Science, PLLC (Benchmark) provided project management on behalf of Tecumseh. The asbestos abatement took place between May 2005 and October 2006. Business Park IA fell within what was referred to at the time as “Area VI” and the following areas were addressed:

Cleanup of Outdoor Asbestos Debris

Boiler House

Power House (ground floor only)

Pumping Station No. 1

The scope of work for the asbestos project involved the removal and disposal of thermal systems insulation, boiler gaskets, pusher car brake shoes, built-up roofing, roof patch tar, window caulk, light fixture insulation, transite pipe, transite lab hoods, transite roofing/ siding, transite electrical switches, galbestos roofing/siding, boiler insulation, exterior tank jacket insulation, exterior pipe/tank tar coating, resilient flooring, floor tile and floor tile mastic from former coke ovens, ancillary buildings and structures prior to their demolition. All work was performed in accordance with the requirements of NY Industrial Code Rule 56, OSHA, USEPA, and all other applicable regulations and standards.

Page 14: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 7

All air samples were analyzed by EMSL Analytical Inc., of Depew, New York. Air samples were considered satisfactory when all results were <0.01 fibers per cubic centimeter (f/cc) or the measured background level (the clearance criteria established by New York State Industrial Code Rule 56).

The manual provided in Appendix A-3 contains records that document the efforts of Watts to ensure the health and safety of the building occupants. Included are the laboratory reports, daily project logs, certifications, and licenses, and consultant’s certifications and licenses.

2.7 Interim Remedial Measures On December 17, 2012, during removal of an old building footer foundation within

the railroad corridor during the East Harbor Lead project, field evidence1 of potentially impacted soil/slag-fill (“black tar-like material”) was encountered. On January 2, 2013, Zoladz Construction Co., Inc. (Zoladz) removed the visually impacted soil/slag-fill and NYSDEC agreed that no further removal of soil/slag-fill was required. The impacted material was stockpiled on polyethylene sheeting east of the railroad corridor adjacent to the impacted area and covered with polyethylene sheeting to prevent infiltration of precipitation and wind erosion. As shown on Figure 3, the area of impact was approximately 20-feet by 30-feet. On January 7, 2013, the excavation area was backfilled with BUD-approved slag and compacted.

On January 24, 2013, TurnKey personnel collected two representative samples of the impacted soil/slag-fill for analysis of TCLP VOCs, TCLP RCRA metals, total PCBs, and ignitability by Test America Laboratories, Inc. of Buffalo. On October 2, 2013, Tecumseh received approval from the Chautauqua County Landfill (CCLF) for disposal as a solid waste. On October 18, 2013, a total of 87.91 tons of the impacted soil/slag-fill was hauled to the CCLF by Zoladz. Documentation is contained within the 2013 Construction Completion Report (Ref. 2).

1 Field evidence of impact is defined as having readily identifiable visual or olfactory signs of contamination, including product, tars, or elevated PID readings (i.e., sustained readings >20 ppm).

3.0 REMEDIAL INVESTIGATION APPROACH & RATIONALE The RI was designed to provide defensible data to identify areas of the Site potentially

requiring remediation, define chemical constituent migration pathways, and qualitatively assess human health and ecological risks to allow for performance of a remedial alternatives evaluation. This section of the RI report presents a discussion of the rationale for the data collection program of the RI, including the methods employed to collect samples and make field measurements and observations, and the methods used to chemically analyze the environmental samples.

3.1 General The RI included the following field activities to delineate and characterize on-site

soil/fill and assess groundwater quality at the Site:

Visual, olfactory, and PID characterization of surface and subsurface soil/fill through test pit excavation.

Collection of surface and subsurface soil/fill samples.

Advancement of on-site borings completed as groundwater monitoring wells.

Collection and analysis of groundwater samples from existing and newly installed monitoring wells at the Site.

RI field activities were conducted by TurnKey in accordance with the approved April 2010 RI/AAR Work Plan for Phase IA Business Park (Ref. 3). Environmental sample collection was performed in accordance with TurnKey’s Field Operating Procedures (FOPs); USEPA- and NYSDEC-approved sample collection and handling techniques were employed. Samples for chemical analysis were analyzed in accordance with USEPA SW-846 methodology to meet the definitive-level data requirements. Analytical results were evaluated by a third-party data validation expert in accordance with provisions described in the RI Work Plan. Most field activities were conducted under NYSDEC oversight. Each sampling location was surveyed via GPS and plotted on the site base map. Appendices A and B include the analytical data packages for samples collected during the April 2007 and June 2010 sampling events, respectively.

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 9

3.2 Constituents of Potential Concern The constituents of potential concern (COPCs) identified in the RI Work Plan were

based on Site operational history, groundwater sampling data, and prior investigation reports. The primary COPCs include base-neutral Target Compound List (TCL) semi-volatile organic compounds (SVOCs) and select metals in surface soil/slag-fill. SVOCs are associated with greases, lubricating and hydraulic oils, and fuels associated with the operation of the steel mills, foundry, petroleum bulk storage and other steel manufacturing operations historically conducted on the Site. Metals associated with steel manufacturing are also ubiquitous in surface and shallow subsurface soil/slag-fill at the Site. The investigation also checked for the presence of PCBs from former transformer use and VOCs from the historical use of solvents and fuel storage.

3.3 Soil/Fill Investigation

Surface Soil Twelve grab surface soil/fill samples identified as BP1A-SS-04 through BP1A-SS-15

(see Figure 3) were collected from the Phase IA Business Park Site in June 2010 to facilitate evaluation of potential health risks to current Site receptors that may be exposed to soil/fill via direct contact, incidental ingestion, or inhalation of airborne particulates. For each surface soil/fill grab sample, a dedicated stainless-steel spoon was used to collect a representative aliquot of soil from 0 to 2 inches below ground surface (bgs) following removal of any sod. Samples were transferred to laboratory supplied, pre-cleaned sample containers for analysis of the parameters listed in Section 3.3.3.

Subsurface Soil/Fill The subsurface investigation included the excavation of 17 test-pits, identified as

BP1A-TP-1 through BP1A-TP-17 (see Figure 3). Test pits were excavated using a track-excavator from ground surface to native soils or groundwater, whichever was encountered first. As outlined in the RI Work Plan, most of the test pit samples were biased toward the upper 2-foot interval, the depth where most exposure is likely to occur prior to and following redevelopment. At locations where field observations suggested a greater potential impact with depth, the sample was collected from the subsurface interval (i.e., 2 feet to native soil/

Page 17: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 10

groundwater depth). No visual or olfactory evidence of impact was observed in the native soils; therefore, samples were not collected for laboratory analysis.

Following test pit excavation, subsurface samples were retrieved by scraping the excavator bucket across the depth from 2 fbgs to the bottom of the test pit and were collected from the center of the excavator bucket using a dedicated stainless-steel spoon. Samples were transferred to laboratory supplied, pre-cleaned sample containers for analysis of the parameters listed in Section 3.3.3.

In accordance with the RI/AAR Work Plan, a representative aliquot was also collected from the sample interval and transferred to a sealable plastic bag for discrete headspace determination. PID headspace readings are shown on the individual test pit excavation logs included as Appendix C. In accordance with the Work Plan, since the PID headspace reading at BP1A-TP-10 was greater than 20 ppm, the sample originally to be analyzed for STARS List VOCs was analyzed for TCL VOCs.

Appendix C includes the field notes and logs for all test pits excavated at the Site. Following completion of each test pit, slag/fill material was returned to the excavation in the opposite order in which it was removed and compacted to match the existing grade.

Methods of Chemical Analysis Surface and subsurface soil/fill samples were couriered under chain-of-custody

command to TestAmerica, Inc., located at 10 Hazelwood Drive, Amherst, New York 14228 for chemical analysis. TestAmerica is an independent, NY State Department of Health (NYSDOH) Environmental Laboratory Approval Program (ELAP)-certified facility approved to perform the analyses prescribed for this RI. TestAmerica also has NYSDOH Contract Laboratory Program (CLP) certification while maintaining ASP accreditation. TestAmerica employed analytical testing methods described in USEPA Test Methods for Evaluating Solid Wastes contained in SW-846 (revised 1991). Surface and subsurface soil/fill samples were analyzed for TCL VOCs, TCL SVOCs, total metals, and PCBs. The soil/fill sample collected from BP1A-TP-9 was also analyzed for TCLP VOCs, SVOCs, and metals, as well as percent solids and flashpoint, to aid in evaluating remedial options.

3.4 Groundwater Investigation Based on previous investigations completed on the adjacent Phase I Business Park,

groundwater modeling indicated that shallow groundwater flows east to west, toward the

RI/AA REPORT PHASE IA BUSINESS PARK

Gateway Metroport Ship Canal and eventually Lake Erie. To supplement this data, three shallow overburden groundwater monitoring wells were installed on the Phase IA Business Park Site.

The following sections describe the groundwater investigation and sampling methodology. Figure 3 shows the monitoring well locations discussed in this section. Appendix C includes the boring and monitoring well construction logs for all wells at the Site.

Monitoring Well Installation Following completion of the soil/fill portion of the investigation, three new shallow

overburden monitoring wells (designated MWN-69A, MWN-70A, and MWN-71A) were installed to better determine groundwater flow direction and groundwater quality on the Phase IA Business Park. The monitoring wells were generally installed at the proposed (RI/AAR Work Plan) locations, with some minor adjustments made in the field as necessary to facilitate drilling.

Monitoring Well Installation Methodology In accordance with the RI/AAR Work Plan, all new wells were constructed of 2-inch

schedule 40 PVC with a lockable J-plug and protected by a vented, 4-inch diameter protective steel casing. Protective steel casings were installed to a depth of approximately 2 fbgs and anchored in a 2-foot by 2-foot concrete surface pad. Table 3 presents monitoring well construction details; the logs are included in Appendix C.

Monitoring Well Development Both the newly installed and existing monitoring wells were developed prior to

sampling using dedicated, disposable, bottom-discharging polyethylene bailers for surging and a peristaltic pump for purging in accordance with NYSDEC and TurnKey protocols.

Groundwater Elevation Measurements Following installation, the locations and elevations of the newly installed monitoring

wells were surveyed against a fixed benchmark and located on the Site plan. The PVC casing tops were referenced to existing Site vertical datum to provide a reference point for groundwater elevation measurements. Groundwater elevations measured on February 8, 2011 indicate that the water table is encountered between 6 and 10 fbgs within the soil/slag-fill unit.

Groundwater flow direction at the Site was assessed using the following 10 well locations: existing off-site upgradient monitoring wells B-2, MWN-64A, and MW-14A through MW-17A; off-site upgradient piezometer P-45S; and three newly installed Site monitoring wells MWN-69A through MWN-71A. Figure 4A is an isopotential map prepared using groundwater elevations measured on February 8, 2011. Examination of the isopotential map indicates that shallow groundwater flows radially west/southwest across the Site towards the Gateway Metroport Ship Canal as well as northwest toward the Buffalo Outer Harbor. Figure 4B presents the isopotential map prepared using the groundwater elevations measured on February 23, 2016; groundwater flow directions are like those established in 2011. Table 4 summarizes the static depth to groundwater measurements from on-site and off-site wells/ piezometers obtained February 2011, May 2014, and February 2016.

Monitoring Well Sampling On June 30, 2010, groundwater quality was assessed by collecting samples from

upgradient wells B-2 and MW-16A; upgradient piezometer P-45S; and Site wells MWN-69A through MWN-71A. Sampling was conducted in accordance with the RI/AAR Work Plan using low-flow sampling methodology. Appendix D includes the well sampling logs.

Groundwater samples were couriered under chain-of-custody command to TestAmerica for analysis of TCL VOCs, TCL SVOCs, PCBs, and inorganic compounds. TestAmerica employed analytical testing methods described in USEPA Test Methods for Evaluating Solid Wastes contained in SW-846, revised 1991.

On May 7, 2014 and February 23, 2016, groundwater samples were collected from Site monitoring wells MWN-69A and MWN-70A for analysis of petroleum VOCs, base-neutral SVOCs, and RCRA metals. Well MWN-71A was damaged; therefore, no groundwater samples were obtained.

3.5 Quality Assurance/Quality Control Field investigation data were collected and processed using the procedures outlined in

the Work Plan to ensure representative sample collection and to achieve the data quality objectives of the Remedial Investigation. The field activities were recorded in bound project field books supplemented with TurnKey field forms, as necessary.

TurnKey collected blind duplicates and matrix spike/matrix spike duplicates (MS/ MSD) at a frequency of 1 per 20 samples for each environmental media (i.e., soil/fill and

0071-010-350 13

groundwater). A trip blank accompanied each cooler of aqueous media to be analyzed for VOCs.

3.6 Data Usability Summary In accordance with the RI/AAR Work Plan, the laboratory analytical data from this

investigation was assessed by an independent third-party data validator. Ms. Judy Harry of Data Validation Services located in North Creek, New York performed the data usability summary assessment for the soil/fill and groundwater samples. The validation involved a review of the summary form information and sample raw data, and a limited review of associated QC raw data. Specifically, the following items were reviewed:

Laboratory Narrative Discussion Custody Documentation Holding Times Surrogate and Internal Standard Recoveries Matrix Spike Recoveries/Duplicate Recoveries Field Duplicate Correlation Preparation/Calibration Blanks Control Spike/Laboratory Control Samples Instrumental IDLs Calibration/CRI/CRA Standards ICP Interference Check Standards ICP Serial Dilution Correlations Sample Results Verification

The data usability evaluations were conducted using guidance from the USEPA Region 2 Validation Standard Operating Procedures, the USEPA National Functional Guidelines for Data Review, as well as professional judgment. Appendix E includes the Data Usability Summary Report (DUSR), which was prepared in accordance with Appendix 2B of NYSDEC’s DER-10 guidance (Ref. 4). Those items listed above that demonstrated deficiencies are discussed in detail in the DUSR. Analytical results that were edited or qualified per the DUSR have been modified appropriately on the summary tables.

3.7 PCB Investigation In concert with the Site characterization activities, TurnKey personnel conducted an

inventory of the remaining electrical equipment within the three buildings on the Phase IA

Page 21: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 14

Business Park Site. As summarized on Table 2A, a total of 36 transformers and 2 oil-filled circuit breakers remained on-site. To determine disposal requirements, liquid samples (and/or wipe samples of the reservoir or housings, in the absence of liquid) were collected from these remaining pieces of equipment and analyzed for total PCBs in general accordance with USEPA Part 761 Subpart N (Cleanup Site Characterization Sampling for PCB Remediation Waste). In addition to electrical equipment sampling, areas of suspected staining not associated with existing or historic transformers were sampled as requested by the NYSDEC. Table 2B summarizes the floor wipe and soil/fill sampling performed within these buildings. Appendix C contains the field notes describing the sampling event.

3.8 Barometric Condenser Cold Well Investigation On June 28, 2010, an on-site assessment of the barometric condenser cold well was

performed to determine whether it was properly decommissioned. An excavator was used to uncover the remaining concrete surface structure. Field observations via exploratory test pits indicated no evidence of the condenser cold well. Following the test pit investigation, TurnKey and the NYSDEC met to review historic record drawings for the condenser cold well, which indicated that it was decommissioned and backfilled to existing grade in August 1973 (see Figure 2).

On September 16, 2010, at the request of the NYSDEC, a soil boring (BP1A-B-01) was advanced to a depth of approximately 23.7 fbgs in the location of the former condenser cold well to confirm record drawings (see Figure 3). Field observations based on split-spoon sampling indicated fill materials (i.e., brick debris/sand/fill) from ground surface to a depth of approximately 20 fbgs. Concrete was observed from approximately 20 to 22.7 fbgs followed by woody debris material. Based on soil boring results and field observations by TurnKey and NYSDEC personnel, no further action was required in the vicinity of the condenser cold well. Appendix C includes the soil boring log for BP1A-B-01.

4.0 RI FINDINGS This Section describes pertinent field observations and chemical analytical results in

surface soil/fill, subsurface soil/fill, groundwater, electrical equipment, and building surfaces.

4.1 Field Observations The surface of the Phase IA Business Park Site is generally characterized as a flat area

covered by sparse brush and low-lying vegetation. The land surface is sparsely vegetated with voluntary indigenous shrubs, grasses, weeds, and emergent trees (mostly poplars).

Due to the nature of the slag/soil fill, there is very little ponded storm water or surface runoff as most of the precipitation seeps into the highly permeable slag/soil fill. Subsurface lithology generally consists of a soil/fill unit comprised of dark brown, non-plastic fines with fine to medium sand, slag, cinders, ash, gravel, cobbles, brick, metal debris, and concrete, all of which are ubiquitous at the Site. This unit is characterized as dense but loose when disturbed. Below the soil/fill unit is a silty clay layer, either native or suspected non-native. A peat layer was occasionally noted below either the soil/fill unit or silty clay unit. Groundwater within the soil/fill unit was generally encountered between 7 and 10 fbgs.

Remaining building structures on the Site include the former Blowing Engine House No.3, Steam Station No.1/Boiler House No.3, and Power House No.3, none of which are currently occupied. The floor surface inside the remaining structures is characterized as weathered concrete and/or slag/fill.

Field evidence of potential significant soil/fill impacts, characterized by moderate to strong odors, unusual discoloration, visible evidence of product layer, and/or PID readings above 50 ppm, was identified at certain test pit locations as presented below. These significant impacts have been noted on Figure 3 and on the test pit logs in Appendix C.

BPA1-TP-9: Strong petroleum-like odor was noted beginning at 1 fbgs through to the fill-groundwater interface. Free floating product was observed on the groundwater at approximately 6 fbgs. A maximum PID reading of 49 ppm was recorded in the subsurface. Through additional test pits near BPA1-TP-9, the extent of the impact was defined as a 15-foot by 45-foot area by 6 feet deep. Two, 3-inch steel pipes were encountered within the impacted area at a depth of 3 fbgs. The pipes were broken and contained tar product. A coal tar lens was identified from 0.5-1.0 fbgs. Sheen was observed on the water at 6 fbgs and petroleum odors were noted.

Page 23: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 16

BPA1-TP-10: Tar-like material was noted within the upper foot of the slag/black sand fill. A moth-ball like odor was detected in the upper 2 feet of the test pit. A PID reading of 44 ppm was detected at 6 inches below grade; the PID reading was 0.0 ppm at 2 fbgs.

BPA1-TP-11: Petroleum-like material was noted within the unsaturated slag/fill in the 0.5-1.0 fbgs interval, with a strong moth-ball like odor. The PID reading at 1 fbgs was 15 ppm and 0.0 ppm at 3 fbgs.

In addition, a sulfur odor was present in the groundwater during development of monitoring well MW-16A on June 25, 2010 but not during purging and sampling on June 30, 2010. Slight sheen was observed during development of monitoring well MWN-71A on June 28, 2010 but not during purging and sampling on June 30, 2010.

4.2 Soil/Fill Chemical data for surface and subsurface soil/fill samples collected during the RI are

discussed in the following sections. As a comparison, Tables 5A (surface soil) and 6A (subsurface soil) include

“Unrestricted Use” Soil Cleanup Objectives (USCOs) as published in 6NYCRR Part 375-6 “Remedial Program Soil Cleanup Objectives.” USCOs are deemed protective of human health and groundwater irrespective of end use of the property. Accordingly, the USCOs represent conservative soil/fill cleanup objectives that are often difficult to achieve on former industrial sites in urban areas. Tables 5B (surface soil) and 6B (subsurface soil) compare the data to CSCOs per 6NYCRR Part 375-6. These values are deemed protective of human health, in the absence of other controls, for sites where end use will be limited to commercial or more restrictive (e.g., industrial) uses, which are considered the reasonably anticipated future uses for the Phase IA Business Park per the land use analysis presented in Section 8.4. Sample locations where reported concentrations exceed respective SCOs are shaded on the data summary tables.

Based on the widespread nature of the USCO exceedances, the discussions below are limited to soil/fill quality as indicated by the more meaningful comparison to commercial use SCOs. To the extent commercial use SCOs are exceeded, USCOs would be exceeded as well.

Page 24: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 17

VOCs No surface soil or test pit locations/samples exhibited exceedance of the CSCOs for

VOCs.

SVOCs Several surface and subsurface samples exhibited exceedances of the CSCOs for one

or more SVOC. Specifically, benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, benzo(k)fluoranthene, chrysene, dibenz(a,h)anthracene, and indeno(1,2,3-cd)pyrene) were reported above CSCOs at several locations; however, the exceedances of these PAHs were generally within one order of magnitude of the SCO. The exception is the sample from test pit BP1A-TP-12 with exceedances within one to two orders of magnitude above the CSCOs for these parameters. In addition, no SVOCs were detected in the TCLP extract of test pit sample BP1A-TP-9.

Inorganic Compounds Arsenic was reported above the CSCO of 16 mg/kg at several test pit locations with

exception of BP1A-TP-1, BP1A-TP-3, BP1A-TP-6, BP1A-TP-8, BP1A-TP-9, and BP1A-TP17. Three of the five surface soil sample locations (SS-09 through SS-11) were characterized by arsenic above the CSCO. Other inorganic compounds reported above CSCOs include cadmium (SS-09 through SS-11), lead (BP1A-TP-14, SS-09 through SS-11), manganese (SS-13 and SS-15), and mercury (BP1A-TP-8, BP1A-TP-10 through BP1A-TP-12, and SS-09 through SS-11). The reported exceedances were generally within one order of magnitude of the CSCOs, except for arsenic in BP1A-TP-2 (120 mg/kg) and SS-09 (158 mg/kg); cadmium in SS-11 (246 mg/kg); and mercury in SS-09 (280 mg/kg), SS-10 (320 mg/kg), and SS-11 (216 mg/kg). No metals were detected above CSCOs in the TCLP extract of test pit sample BP1A-TP-9.

Polychlorinated Biphenyls PCBs were not detected above CSCOs in any of the test pit or surface soil sample

locations.

4.3 Groundwater Groundwater quality data was collected during the RI (June 2010) from existing off-

site upgradient wells/piezometers: MW-16A, P-45S, and B-2; and newly installed overburden wells MWN-69A, MWN-70A, and MWN-71A. Well MW-16A and piezometer P-45S were decommissioned in September 2012 during the Railroad Realignment project. Appendix D includes the decommissioning logs prepared by Earth Dimensions Inc. showing decommissioning via tremie grouting in place. In May 2014 and February 2016, groundwater samples were collected from Site monitoring wells MWN-69A and MWN-70A; a sample could not be obtained from MWN-71A as it has been damaged. In June 2018, emergent contaminant samples were collected from monitoring wells MWN-69A and MWN-70A. Table 3 summarizes groundwater monitoring well construction details. Tables 7 and 8 summarize the analytical data, including field QC samples, along with Class GA Groundwater Quality Standards and Guidance Values (GWQS/GVs) per NYSDEC June 1998 Division of Water Technical and Operational Guidance Series (TOGS) 1.1.1. The findings are discussed below.

VOCs Groundwater samples from June 2010 exhibited non-detectable or trace (estimated)

concentrations of VOCs well below the GWQS/GVs. No VOCs were detected in the samples collected in May 2014 and February 2016.

SVOCs All samples obtained from groundwater monitoring wells exhibited non-detectable,

low, or trace (estimated) concentrations of SVOCs below GWQS/GVs. No SVOCs were detected in the samples collected in May 2014 or February 2016.

Inorganic Compounds Total metal concentrations were reported as non-detect, or at concentrations well

below GWQS/GVs for all metals during the June 2010 sampling event except for iron, manganese, and sodium in well MWN-71A, and total lead (slightly above) in piezometer P-45S. During the February 2016 sampling event, there were slight exceedances of the GWQS/GVs for manganese in well MWN-69A and cyanide and manganese in well MWN-70A. Manganese was also detected in the method blank sample for both wells. Iron and

0071-010-350 19

manganese are naturally occurring elements in groundwater and are not considered a health risk. Cyanide was reported in well MWN-70A as an estimated concentration of 1.0 mg/L, which is slightly above the GWQS of 0.2 mg/L.

Polychlorinated Biphenyls Groundwater samples exhibited non-detectable concentrations of PCBs during the

June 2010, May 2014, and February 2016 sampling events.

Emergent Contaminants TurnKey submitted the results of the July 2018 emergent contaminant sampling event

to NYSDEC in a letter dated August 3, 2018. Low level concentrations of per- and polyfluoroalkyl substances (PFAS) were detected at both sampling locations above laboratory detection limits including the field blank. The individual PFOA and PFOS concentrations in well MWN-70A exceeded the proposed drinking water standard of 10 nanograms per liter (ng/L); however, the NYSDEC PFOA+PFOS action level of 70 ng/L was not exceeded. Total PFAS concentrations did not exceed the NYSDEC action level of 500 ng/L at either well; in fact, the highest total PFAS concentration was 66.5 ng/L. 1,4-Dioxane was reported as non-detect at both monitoring locations.

Groundwater Field Measurements Field pH was measured immediately before and after groundwater sample collection.

According to TOGS 1.1.1., the maximum allowable pH ranges between 6.5 and 8.5. As indicated on Table 7, the pH measurements at monitoring well MWN-69A (6.17 and 6.37) and MWN-70A (6.46) were slightly outside this range during the June 2010 sampling. During the May 2014 sampling, only the final pH reading from well MWN-69A (6.42) was slightly outside this range. All pH reading during the February 2016 sampling were within the allowable range.

4.4 Electrical Equipment and Building Surfaces Table 9 summarizes the transformer oil analytical results of the remaining electrical

equipment identified on Table 2A. Based on the analytical results, each of the remaining pieces of electrical equipment was characterized into one of the following three categories as defined

Page 27: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 20

by PCB analytical concentrations in accordance with USEPA Part 761.60 (Disposal Requirements).

Non-PCB Equipment contains liquid PCB concentrations <50 ppm or surface concentrations ≤10 ug/100 cm2.

PCB-Contaminated Equipment contains liquid PCB concentrations ≥50 ppm to <500 ppm or surface concentrations >10 ug/100 cm2 to <100 ug/100 cm2.

PCB-Equipment contains liquid PCB concentrations ≥500 ppm or surface concentrations ≥100 ug/100 cm2.

As indicated on Table 9, all remaining electrical equipment is characterized as “non-PCB.” Table 10A presents the results of wipe samples collected from the building surfaces in

Power House No. 1 (at the request of NYSDEC) in June 2010. Three wipe samples (T-118 North Floor Wipe, T-141-143 Floor Wipe, and T-144-146 Floor Wipe) were reported at levels above 10 ug/m2. In accordance with 40 CFR Part 761.125, low-contact impervious surfaces are to be cleaned to 10 ug/m2 following release of PCB-contaminated oil. The estimated areal extent requiring cleaning was approximately 300 square feet.

As shown on Table 10A, the sample collected from the fill material on the floor surface of the Blowing Engine House No. 3 building (at the request of NYSDEC) indicates a non-PCB material. A sample collected from the fill material on the floor surface of the Power House No. 1 building indicated a PCB concentration slightly above the CSCO of 1 mg/kg but below the industrial SCO (ISCO) of 25 mg/kg. Because indoor soils pose an exposure scenario more consistent with that of a commercial use scenario than an industrial scenario (e.g., potential for routine exposures by indoor workers and visitors), the NYSDEC has indicated that the presence of surface concentrations above 1 mg/kg in an indoor area warrants remediation consistent with DER-10 and its CP-51 Soil Cleanup Guidance Policy.

Completed Remedial Measures On April 22, 2016, TurnKey (in association with Benchmark Environmental

Engineering & Science, PLLC) scraped the dust/soil from the floor, swept, and vacuumed the areas to be cleaned. The NYSDEC Project Manager was on-site and selected five areas for cleaning and PCB wipe sampling due to suspect oil staining on the floor. A muriatic acid-based concrete etcher/cleaner was scrubbed into the concrete and rinsed with water. The areas were vacuumed to remove excess water. The cleaned surface was left to air dry. On April 25, 2016,

Page 28: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 21

TurnKey-Benchmark collected 10 PCB wipe samples, five near the transformers and five where oil staining was observed; NYSDEC was on-site to observe the wipe sampling.

As shown on Table 10B, 3 of the 10 sample results exceeded 10 ug/100 cm2. On May 3, 2016, TurnKey-Benchmark re-cleaned these areas and collected three additional wipe samples. Following this cleaning, only 2 of the 3 sample results exceeded 10 ug/100 cm2. The remaining impacted area near transformers T144-T146 was cleaned again on May 13 and 26, and two wipe samples were collected after each event. Although the concentrations were reduced through cleaning, this approximate 88 square foot area is still impacted by elevated levels of PCB Aroclor 1254; therefore, additional focused remedial work is required to address this portion of the building floor.

In 2016, TurnKey drained and segregated the oil from the transformers based on PCB concentration. The non-PCB oil (approx. 262 gallons) was picked up by NOCO Distribution LLC on May 2, 2016 for reuse. On March 21, 2016, Clean Harbors Environmental Service, Inc. transported the transformer oil drained from the equipment, transformer residuals and carcasses, and capacitors to its facility in Twinsburg, OH. Tecumseh received the Certificates of Disposal indicating the methods of disposal in May through August 2016.

5.0 FATE AND TRANSPORT OF COPCS Soil/fill sample results exceed SCOs for certain chemicals of concern (COCs). In

addition, floating petroleum product was observed on the water within test pit BP1A-TP-9 at approximately 6 fbgs. Accordingly, the soil/fill data and field observations were incorporated with the physical characterization of the Site to evaluate the fate and transport of COCs in Site media. The mechanisms by which the COCs present above SCOs can migrate to other areas or media are briefly outlined below.

5.1 Airborne Pathways Potential migration pathways involving airborne transport of soil/fill COCs include

erosion and transport of soil particles and sorbed chemical constituents in fugitive dust emissions, and volatilization from subsurface soil vapor.

Fugitive Dust Chemicals present in soil/fill can be released to ambient air because of fugitive dust

generation. Since the Site is presently unoccupied and substantially vegetated with shrubs, grasses, and trees, and because most of the fill consists of large grained slag, suspension due to wind erosion or physical disturbance of surface soil/fill particles is unlikely under the current use scenario. Under the planned future commercial/industrial land use, much of the Site would be covered by asphalt and structures with only small areas covered by grass and/or ornamental landscaping. Fugitive dust may be generated during excavation activities either during or following redevelopment. Therefore, this migration pathway is potentially relevant under the reasonably anticipated future land use scenario.

Volatilization Volatile chemicals, when present in soil/fill at elevated levels, may be released to

ambient air or future building indoor air through volatilization from or through the soil/fill pore space. Volatile chemicals typically have a low organic-carbon partition coefficient (Koc), low molecular weight, and a high Henry’s Law constant. However, VOCs were not detected in Site soil/fill at concentrations above CSCOs. Similarly, groundwater samples yielded not-detectable or trace levels of VOCs below Class GA GWQS/GVs. Therefore, the soil and groundwater-to-air pathways are not relevant.

Page 30: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 23

5.2 Waterborne Pathways

Surface Water Runoff Under the current use scenario, the potential for soil particle transport via surface water

runoff is mitigated by the flat topography of the Site and significant amount of vegetative growth. In addition, the well-drained soil/fill matrix precludes surface water ponding. Uncontrolled off-site transport is further limited because the Site is outside the 100-year floodplain. Although the Site is transected by the North and South Return Water Trenches, they are constructed in this area of the property as brick-lined channels with elevated wall sections, preventing surface run-in.

Under the reasonably anticipated future use scenario, the Site will be substantially covered by asphalt, buildings, and landscaping, mitigating transport of subsurface (i.e., covered) soil/fill via storm water runoff. Although stormwater runoff during excavation activities is possible during the future use scenario, erosion controls are typical construction practice and would be implemented as a component of the Site Management Plan required for BCP sites that do not achieve unrestricted use conditions.

Leaching No exceedances of the Class GA Groundwater Quality Standards and Guidance Values

(GWQS/GVs) were identified in on-site or off-site upgradient groundwater monitoring wells samples except for select metals. In addition, the soil/fill sample from BP1A-TP-9 was analyzed for TCLP metals and VOCs; the TCLP concentrations were well below the regulatory limits for hazardous waste determination, indicating chemical leaching is not a likely migration pathway. Nevertheless, the presence of free floating product (LNAPL) observed on the groundwater at approximately 6 fbgs in BP1A-TP-09 indicates isolated smear zone impact by petroleum product, suggesting localized saturation conditions. Accordingly, chemical (petroleum) migration via leaching is considered a potentially relevant exposure pathway.

Groundwater to Surface Water Migration As indicated on Table 7, all parameters during the 2010 RI were reported at or below

the Class GA GWQS/GVs except for minor pH deviations recorded in wells MWN-69A and MWN-70A. This data indicates that although saturated soil impact by petroleum was observed

Page 31: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 24

at BP1A-TP-9, this impact is likely isolated. To further assess whether site-wide groundwater to surface water migration is a relevant pathway, groundwater was sampled in May 2014 and February 2016. As described in Section 4.3, Site groundwater near monitoring wells MWN-69A and MWN-70A is not impacted; therefore, impact to groundwater from source areas appears isolated. If groundwater is impacted near hotspot areas, the groundwater to surface water migration pathway would be relevant. Neither well exceeded the NYSDEC action level for PFOA+PFOS or total PFAS concentrations indicating groundwater does not require additional monitoring. Well MWN-70A slightly exceeds the individual PFOA and PFOS proposed drinking water maximum contaminant level; however, the existing deed restriction prohibits the use of groundwater for potable purposes.

5.3 Exposure Pathways Based on the analysis of chemical fate and transport provided above, the only pathways

through which Site COCs could potentially migrate to other areas or media are fugitive dust emissions via physical disturbance of soil particles and potential leaching of petroleum products from the smear zone to groundwater. However, given the absence of existing Site occupancy; the distance between the Site and occupied structures; the availability of a municipal water supply and NYSDEC/NYSDOH requirements for dust controls during excavation at remedial program construction sites, it is unlikely that site-related COCs would reach off-site receptors at significant exposure point concentrations.

6.0 QUALITATIVE HUMAN HEALTH EXPOSURE AND WILDLIFE

IMPACT ASSESSMENT

6.1 Human Health Exposure Assessment A qualitative exposure assessment consists of characterizing the exposure setting

(including the physical environment and potentially exposed human populations), identifying exposure pathways, and evaluating contaminant fate and transport.

An exposure pathway describes how an individual may be exposed to contaminants originating from a site. An exposure pathway has five elements:

A receptor population A contaminant source A contaminant release and transport mechanism A point of exposure A route of exposure

The receptor population is the people who are or may be exposed to contaminants at a point of exposure. The source of contamination is defined as either the source of contaminant release to the environment (such as a waste disposal area or point of discharge), or the impacted environmental medium (soil, air, biota, water) at the point of exposure. Contaminant release and transport mechanisms carry contaminants from the source to points where people may be exposed. The point of exposure is a location where actual or potential human contact with a contaminated medium may occur. The route of exposure is the way a contaminant enters or contacts the body (i.e., ingestion, inhalation, dermal absorption).

An exposure pathway is complete when all five elements of an exposure pathway are documented; a potential exposure pathway exists when any one or more of the five elements comprising an exposure pathway is not documented but could reasonably occur. An exposure pathway may be eliminated from further evaluation when any one of the five elements comprising an exposure pathway does not exist in the present and will not exist in the future.

Potential Receptors The identification of potential human receptors is based on the characteristics of the

Site, the surrounding land uses, and the probable future land uses. The Phase IA Business Park Site is presently unoccupied. Under current Site use conditions, receptors would be limited to

Page 33: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 26

trespassers who may traverse the Site (although presently mitigated by fencing and security measures); and construction workers that may access the Site to service utilities or perform similar duties. Trespassers might be comprised of adolescents and adults, whereas construction workers would be limited to adults. During remedial actions, receptors would include remedial contractors, environmental oversight personnel, and staff from regulatory agencies. Consideration and mitigation of remedial contractor exposure is conservatively protective of regulatory staff.

In terms of future use, the current Site owner (Tecumseh Redevelopment) has developed a Master Plan for commercial/industrial redevelopment of the Site consistent with surrounding property use and site zoning. Future site use is further discussed under Section 8.4, which indicates that the reasonably anticipated future use of the Site is for commercial/ industrial purposes. Exposed receptors under the future use scenario may be comprised of indoor workers, outdoor workers (e.g., groundskeepers or maintenance staff), and construction workers who may be employed at or perform work on the property. Site visitors/ customers may also be considered receptors; however, their exposure would be like that of the indoor worker but at a lesser frequency and duration. Therefore, consideration and mitigation of indoor worker exposure is conservatively protective of the site visitor.

Contaminant Sources Section 4.0 discusses the COCs present in un-remediated Site media at elevated

concentrations. In general, these are limited to SVOCs and select inorganic COCs in both surface and subsurface soil/fill, and isolated petroleum impact to the smear zone.

Contaminant Release and Transport Mechanisms Contaminant release and transport mechanisms are specific to the type of contaminant

and site use. For the non-volatile COCs present in site-wide soil/fill, contaminant release and transport mechanisms will generally be limited to fugitive dust migration and direct contact during intrusive work (e.g., during construction and grounds keeping activities), as the Site is currently covered by vegetation and will be substantially covered by roads, parking lots, buildings, and landscaping after redevelopment. VOCs are not present in the surface or subsurface soil/fill and groundwater; therefore, the potential does not exist for exposure through pathways associated with soil gas migration (i.e., indoor vapor intrusion). For the

0071-010-350 27

petroleum product observed on the water table in test pit BP1A-TP-9, smear zone to groundwater is a potential contaminant release and transport mechanism.

Point of Exposure Based on the widespread exceedance of CSCOs for certain ubiquitous parameters (e.g.,

arsenic and PAHs), the point of exposure is defined as the overall Site. For both the current and future use scenarios, groundwater is not considered to pose a relevant mechanism due to the isolated smear zone impact, the availability of a local municipal potable water source, the depth to groundwater (greater than 4.5 feet; the standard depth of utilities and foundation footers), and the existence of a deed restriction that does not allow the use of Site groundwater.

Route of Exposure Based on the types of receptors and points of exposure identified above, potential

routes of exposure are listed below:

Current Use Scenario

Construction and Outdoor Worker – skin contact, inhalation, and incidental ingestion

During Remedial Action Scenario

Remedial Contractor and Environmental Professional – skin contact, inhalation, and incidental ingestion

Future Use Scenario

Indoor Worker – inhalation

Construction and Outdoor Worker – skin contact, inhalation, and incidental ingestion

Exposure Assessment Summary Based on the above assessment, the potential exposure pathways for the un-remediated

site condition are listed below.

Page 35: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 28

Current Use Scenario

Construction and Outdoor Worker – direct contact, incidental ingestion, and inhalation of non-volatile COCs present in site-wide soil/fill during intrusive and other dust-generating activities.

Remedial Action Scenario

Remedial Contractor and Environmental Professional – direct contact, incidental ingestion, and inhalation of non-volatile COCs present in site-wide soil/fill during intrusive and other dust-generating activities.

Future Use Scenario Construction and Outdoor Worker – direct contact, incidental ingestion, and

inhalation of non-volatile COCs present in site-wide soil/fill during intrusive activities

In most instances, these exposures can be readily mitigated during and following redevelopment through proper soil/fill management and placement of asphalt, building, and landscape cover.

6.2 Fish and Wildlife Impact Assessment (FWIA) The Site has been vacant since the former BSC steel plant ceased production in 1983.

The historical use of the Site has eliminated most native species. The Site is mainly populated by low-lying vegetation and small stature early successional trees (e.g., eastern cottonwood and poplar). Vegetative cover has recolonized the vacant industrial site with scrub-like brush and trees. A mixture of cover types exists on the site, ranging from asphalt roadways, rail, and concrete foundation, to spots of dense scrub-brush/cottonwood vegetation. Much of the fauna found on the Site are avian and small mammal species apart from the white-tailed deer. No federally listed or proposed threatened or endangered species are known to exist in the project area (USFWS 1999).

The Phase IA Business Park is slated for redevelopment as a commercial/light industrial area, consistent with surrounding property. Roadways, buildings, parking facilities, and maintained ornamental landscaping will substantially limit availability of suitable cover type for reestablishment of biota.

The only observed impact to groundwater/smear zone with the potential to affect surface water is present near BP1A-TP-9, where petroleum product was observed on the test

Page 36: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 29

pit water at approximately 6 fbgs. This impacted area is upgradient of the NRWT, which flows north to discharge near the confluence of the Union Ship Canal and Buffalo Outer Harbor. This portion of the NRWT is constructed of brick and concrete, is hemlock-wood lined, and extends approximately 8 to 10 fbgs. It is unlikely that the impacts observed in BP1A-TP-9 are discharging to the surface water via NRWT; however, if left unremediated, the potential for impact remains.

As such, based on the Fish and Wildlife Resource Impact Analysis Decision Key included as Appendix F (NYSDEC DER-10 guidelines, Appendix 3C), no fish and wildlife resource impact analysis is warranted.

6.3 Qualitative Off-Site Exposure Assessment During the RI, soil borings were advanced and monitoring wells were installed across

the Site, including locations proximate to Site property boundaries. These sampling locations were used in conjunction with previously collected data to complete this qualitative off-site exposure assessment and evaluate potential remedial measures to address Site contamination. Groundwater flow direction on the Site is southwesterly to westerly. The following evaluates the potential for off-site impacts:

Northern Boundary of Site: Analytical soil data from test pit BPIA-TP-17 near the northern property boundary

shows no concentrations above CSCOs and only two PAHs and four metals (i.e., cadmium, chromium, lead, mercury) above USCOs. There are no hotspots near the northern boundary of the Site. In 2010, monitoring well MWN-71A contained concentrations of iron, manganese, and sodium at concentrations above GWQSs; VOCs and SVOCs were not detected. Therefore, the potential for off-site impacts at the northern boundary is negligible.

Southern Boundary of Site: Analytical soil data from test pit BPIA-TP-1 (approx. 180 feet from the southern

property boundary) shows no concentrations above CSCOs and only one metal (i.e., chromium) above USCOs. There are no hotspots near the southern boundary of the Site. Monitoring well MWN-69A is the closed well to the southern boundary; the only exceedances of the GWQSs were pH slightly below the range. Therefore, the potential for off-site impacts at the southern boundary is negligible.

Page 37: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 30

Eastern Boundary of Site: Soil/fill impacts were observed along the eastern property boundary and have been

identified as Hotspots A, B, G, and H (petroleum, metals). Following excavation of these hotspots, off-site soil/fill impacts at this property boundary will be remediated. In addition, any visually impacted groundwater in Hotspot A would be treated. Therefore, the potential for off-site impacts at the eastern boundary is negligible.

Western Boundary of Site: Soil/fill Hotspot D (PAHs, lead) has been identified along the western property

boundary. Following excavation of this and other interior hotpot areas, off-site soil/fill impacts at this property boundary will be remediated. In 2016, only cyanide (estimated) and manganese (also in method blank sample) slightly exceeded GWQSs in monitoring well MWN-70A; VOCs and SVOCs were not detected. Therefore, following hotspot excavation, the potential for off-site impacts at the western boundary is negligible

7.0 SUMMARY AND CONCLUSIONS The RI findings indicate conditions consistent with the historic use of the Site for steel-

making, and the widespread presence of fill materials containing slag. Key observations and findings from the soil/fill and groundwater investigations are listed below:

Field observation of potential subsurface impact by petroleum was recorded at test pit location BP1A-TP-9. As discussed in Section 4.1, strong petroleum-like odor was noted beginning at 1 fbgs through to the fill-groundwater interface. Free floating product was observed on the groundwater at approximately 6 fbgs. A maximum PID reading of 49 ppm was recorded in the subsurface. The sample collected from 1.0 to 5.5 fbgs yielded VOC and SVOC concentrations below CSCOs except for slight exceedances for individual PAHs, suggesting that the observations are representative of residual, weathered organics. Exploratory test pit investigation near BP1A-TP-9 documented that the visually impacted subsurface soil/fill appears to be a localized within a 15-foot x 45-foot area to a depth of 6 fbgs west of the former tank saddle. Two, 3-inch steel pipes were encountered within the impacted area at a depth of 3 fbgs; the pipes were broken and contained tar product. A coal tar lens was identified from 0.5-1.0 fbgs. Sheen was observed on the water at 6 fbgs and petroleum odors were noted. Based on the TCLP data, excavated soil/fill would be disposed as non-hazardous.

A moth-ball like odor was detected in upper unsaturated zones in test pits BP1A-TP-10 and BP1A-TP-11. The sample collected from BP1A-TP-10 (0 to 2 fbgs) yielded a total VOC concentration (4.7 ppm), which is below the CSCO for total VOCs of 10 ppm; naphthalene (known for its moth-ball like odor) was not detected. The sample collected from BP1A-TP-11 (0.5 to 3.0 fbgs) yielded a total VOC concentration of 279 ppm, which exceeds the CSCO for total VOCs of 10 ppm. The concentration of naphthalene in this sample was 260 ppm, which is below the CSCO of 500 ppm (see the following bullet for explanation of this SCO). SVOC concentrations, particularly the base-neutral PAHs, were above CSCOs. The naphthalene result has been flagged with a “B” qualifier indicating the presence of naphthalene in the associated blank QA/QC sample.

Base-neutral SVOCs (i.e., PAHs) were detected above the CSCOs at several test pit locations across the Site. As discussed in Section 8.3, NYSDEC’s CP-51 Soil Cleanup Guidance provides for an alternative soil cleanup objective of 500 ppm total SVOCs (in lieu of individual SCOs) for soils where: end use of the site will be for commercial or industrial purposes; a cover system (one foot of clean soil, building and/or pavement) will be constructed; and institutional controls and a Site Management Plan will be implemented. Total PAH concentrations were reported at less than 500 ppm, except for subsurface soil samples BP1A-TP-7 (1,192 ppm);

Page 39: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 32

BP1A-TP-11 (1,255 ppm); and BP1A-TP-12 (1,837 ppm). In addition, a total PAH concentration of 2,877 ppm was reported for April 2007 surface soil sample SS-03.

Arsenic was detected above the CSCO of 16 mg/kg at many of the surface and subsurface soil sample locations. Arsenic is a ubiquitous metal with urban background soils in New York State frequently containing concentrations above the CSCO, particularly at active and former industrial properties characterized by historic slag fill deposition and coal burning, such as that which occurred on the subject property. Accordingly, comparison of the arsenic data to site-specific background or average concentrations is considered appropriate. As discussed in Section 8.3, a site-specific SCO of 118 ppm has been established as the screening criteria for hotspot identification. Two areas on the Phase IA Business Park exceeded this site-specific SCO: BP1A-TP-2 (120 ppm) and SS-09 (158 ppm).

Although barium was detected in surface soil/fill sample SS-02 at a concentration (6,630 mg/kg) above the CSCO (400 mg/kg), the concentration is well below the ISCO of 10,000 mg/kg (i.e., cap for total metals) and barium was not detected in adjacent subsurface soil/fill samples collected from BP1A-TP-13 and BP1A-TP-14.

Cadmium concentrations in surface soil samples SS-09, SS-10, and SS-11 exceeded the CSCO of 9.3 mg/kg; however, only the concentration of cadmium at SS-11 (246 mg/kg) exceeded the ISCO of 60 mg/kg.

An elevated lead concentration of 2,530 mg/kg was detected at BP1A-TP-14; however, this concentration is below the ISCO of 3,900 mg/kg. Similarly, the lead concentration (1,090 mg/kg) in surface soil sample SS-03 (April 2007) slightly exceeded the CSCO but fell below the ISCO. The concentrations of lead in surface soil/fill samples SS-09 through SS-11 exceeded but were within one order of magnitude of the ISCO.

Manganese was detected in surface soil/fill samples SS-13 (17,300 mg/kg) and SS-15 (16,000 mg/kg) at concentrations above the CSCO of 10,000 mg/kg (i.e., cap for total metals). According to Table 9.1-10 of the NYSDEC’s BCP Technical Support Document (Ref. 5), the SCO for manganese after consideration of health risk is 67,000 mg/kg for industrial use.

Mercury concentrations in surface soil samples SS-09, SS-10, and SS-11 exceeded the CSCO of 2.8 mg/kg by two orders of magnitude. The concentrations of mercury in subsurface soil/fill samples BP1A-TP-10 through BP1A-TP-12 were within one order of magnitude of the CSCO. Mercury was detected in BP1A-TP-8 at a concentration (6.05 mg/kg) slightly above the ISCO of 5.7 mg/kg.

There were no exceedances of the Class GA GWQS/GVs in any of the groundwater samples collected, except for slight exceedances of cyanide in MWN-

70A (2016), lead in piezometer P-45S (2010) and naturally occurring minerals iron, manganese, and sodium.

Groundwater pH was slightly outside the range during sampling of MWN-69A (2010, 2014) and MWN-70A (2010). A sulfur odor was present in the groundwater during development of monitoring well MW-16A on June 25, 2010 but not during purging and sampling on June 30, 2010. Slight sheen was observed during development of monitoring well MWN-71A on June 28, 2010 but not during purging and sampling on June 30, 2010. Petroleum product was observed floating on the water within test pit BP1A-TP-9 at approximately 8 fbgs, indicating potential localized impact to the saturated soil/fill (i.e., smear zone) due to past Site operations.

Although the individual PFOA and PFOS concentrations in well MWN-70A slightly exceeded the proposed drinking water standard, the NYSDEC action levels for PFOA+PFOS and total PFAS were not exceeded. Therefore, no remedial measures for emergent contaminants in groundwater is warranted.

PCB concentrations detected in low-contact building surfaces do not suggest a high concentration source release. Three floor wipe samples (T-118 North Floor Wipe, T-141-143 Floor Wipe, and T-144-146 Floor Wipe) exceed EPA recommended cleanup criteria for restricted access areas.

No PCBs were detected in any of sampled electrical equipment (i.e., transformers and circuit breakers) at levels above regulatory limits (i.e., 50 ppm).

Based on the RI Findings, remedial measures are warranted to address impacted unsaturated and saturated soil/fill as well as floor surface in the Power House. The remaining sections constitute an Alternatives Analysis Report (AAR) in accordance with NYSDEC DER-10 guidance.

8.0 DEVELOPMENT OF REMEDIAL ACTION OBJECTIVES AND

GENERAL RESPONSE ACTIONS The development of an appropriate remedial approach begins with definition of site-

specific Remedial Action Objectives (RAOs) to address substantial human health and ecological risk or other significant environmental issues identified. General Response Actions are then developed as potential means to achieve the RAOs.

8.1 Remedial Action Objectives RAOs for this Site have been developed based on the findings of the RI, which have

identified localized “hotspot” soil/fill in discrete portions of the Site and smear zone impact near test pit BP1A-TP-9. Hotspots are soil/fill areas where non-ubiquitous constituents significantly exceed ISCOs and/or had notable field observations indicating gross contamination (free product, significant staining, excessive odor, high PID readings). Those areas with soil/fill above the CSCOs will require cover under commercial reuse scenarios; however, unless these soils are also grossly impacted, no further investigation or remediation is warranted. The hotspots for the Site include:

Petroleum impact in test pit BP1A-TP-9 (i.e., petroleum odors with floating product on test pit water).

Visually impacted layer of fill material with moth-ball like odor in the upper 2 feet at test pit locations BP1A-TP-10 (tar-like) and BP1A-TP-11 (petroleum-like).

PAH-impacted surface and subsurface soil/fill near SS-03, BP1A-TP-7, BP1A-TP-11, and BP1A-TP-12 with total SVOC concentrations above 500 ppm.

Mercury-impacted surface soil/fill near SS-09 through SS-11, and subsurface soil/fill near BP1A-TP-10 through BP1A-TP-12.

Lead-impacted surface soil/fill near SS-09 through SS-11.

Cadmium-impacted surface soil/fill near SS-09 through SS-11.

Arsenic-impacted surface soil/fill near SS-09 and BP1A-TP-2.

In developing the RAOs, consideration is given to the reasonably anticipated future use of the Site as further discussed in Section 8.4 (i.e., for commercial and/or industrial purposes), and the applicable Standards, Criteria, and Guidance (SCGs), including soil cleanup guidance per 6 NYCRR Part 375 and GWQS/GVs per Technical and Operational Guidance Series (TOGS) 1.1.1. Accordingly, the RAOs for the Site are to:

Page 42: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 35

Remediate hotspot unsaturated surface and saturated subsurface soil/fill as described above.

Mitigate exposure to soil/fill where contaminant levels exceed CSCOs.

Mitigate exposure to PCBs on surfaces where contaminant levels exceed the cleanup criteria of 10 ug/100 cm2.

Implement and maintain engineering and institutional controls to assure that the Site is not used in a manner inconsistent with the reasonably anticipated future use scenario.

As discussed in Section 4.4.1, two post-cleaning floor wipe samples (i.e., T-144-146-2A and T-144-146-2B) collected from the Power House No. 1 building floor remain above the USEPA recommended PCB cleanup criteria for low-contact restricted access areas. While these areas are indoors in unoccupied buildings and do not necessarily represent an environmental condition under the current use scenario, they should be treated as building contaminants and addressed prior to building reuse and/or in concert with building demolition.

8.2 General Response Actions General Response Actions are broad classes of actions that may satisfy the RAOs.

General response actions form the foundation for the identification and screening of remedial technologies and alternatives. General Response Actions considered for the Site are:

Excavation and on-site treatment or off-site disposal of impacted soil/fill.

Engineering controls or cover to mitigate contact and contaminant transport.

Institutional controls (e.g., deed restrictions and other administrative measures) to restrict use of the Site and mitigate unacceptable exposure.

8.3 Standards, Criteria and Guidance (SCGs) This section provides a summary of the standards, criteria, and guidance (SCGs) that

are considered applicable or relevant and appropriate to remediation of the Site. SCGs include New York State laws, regulations, and guidance as well as more stringent Federal requirements.

Applicable SCGs pertain to cleanup standards, standards of control, and other substantive requirements, criteria, or limitations promulgated under NY State or Federal environmental or facility siting laws that specifically address a hazardous substance, pollutant,

Page 43: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 36

contaminant, remedial action, location, or other circumstance at a site. An applicable requirement must directly and fully address the situation at the site.

Relevant and appropriate SCGs pertain to cleanup standards, standards of control, or other substantive requirements, criteria, or limitations promulgated under NY State or Federal environmental or facility siting laws that, while not “applicable” to a hazardous substance, pollutant, contaminant, remedial action, location, or other circumstance at a site, address problems or situations sufficiently like those encountered at the site that their use is well suited to the particular site.

SCGs are classified as chemical-, action-, or location-specific. Additional discussions concerning the specific chemical, action and location-specific SCGs that may be applicable, relevant, or appropriate to remedy selection at the Site are presented below. In each case, the identified SCGs are generally limited to regulations or technical guidance in lieu of the environmental laws from which they are authorized, as the laws are typically less prescriptive in nature and are inherently considered in the regulatory and guidance evaluations.

Chemical-Specific SCGs Chemical-specific SCGs are usually health- or risk-based concentrations in

environmental media (e.g., air, soil, water), or methodologies that when applied to site-specific conditions, result in the establishment of concentrations of a chemical that may be found in, or discharged to, the ambient environment. The determination of potential chemical-specific SCGs for a site is based on the nature and extent of contamination; potential migration pathways and release mechanisms for site contaminants; the presence of human receptor populations; and the likelihood that exposure to site contaminants will occur.

The RI performed for the Phase IA Business Park provides this information. RI sampling events included the collection and analysis of surface soil, subsurface soil, groundwater, and PCB wipe samples. Table 11 presents a list of chemical-specific NY State and Federal SCGs that may be applicable or relevant and appropriate to the Site.

Groundwater samples collected during the RI were compared to NYSDEC Class GA GWQSs/GVs. According to NYSDEC CP-51 Soil Cleanup Guidance (Ref. 6), NYSDEC may approve a remedial program that achieves a soil cleanup level of 500 mg/kg for total PAHs for all subsurface soil on non-residential use sites. The 500 mg/kg soil cleanup level is in lieu of achieving all the PAH-specific SCOs in 6 NYCRR 375-6. Therefore, this CP-51 soil

Page 44: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 37

guidance level is proposed for the Site. One of the remedial alternatives to be assessed for the Site is a Track 4 cleanup for soil/fill; therefore, a site-specific action level (SSAL) for arsenic was developed for the Site. Arsenic is a ubiquitous metal with urban background soils in New York State frequently containing concentrations above the CSCO (16 mg/kg). Accordingly, comparison of the arsenic data to site-specific background or average concentration is considered appropriate. To determine the Site background concentration, all surface and sub-surface soil/fill arsenic data for the Phase IA Business Park was tabulated and the 95% upper confidence limit (95% UCL) on the mean was calculated (see Appendix G). Based on this analysis and further discussions with the NYSDEC, a site-specific SCO of 118 ppm has been established as the screening criteria for hotspot identification.

Location-Specific SCGs Location-specific SCGs generally are restrictions imposed when remedial activities are

performed in an environmentally sensitive area or special location. Some examples of special locations include floodplains, wetlands, historic places, and sensitive ecosystems or habitats.

The location of the Site is a fundamental determinant of its impact on human health and the environment. Location-specific SCGs are restrictions placed on the concentration of hazardous substances or the conduct of activities solely because they are in a specific location. Some examples of these unique locations include floodplains, wetlands, historic places, and sensitive ecosystems or habitats. Table 12 presents the location-specific SCGs that may be applicable or relevant and appropriate to the Site.

Action-Specific SCGs Action-specific SCGs are restrictions placed on certain treatment or disposal

technologies. Examples of action-specific SCGs are effluent discharge limits and hazardous waste manifest requirements.

Table 13 identifies action-specific SCGs that may significantly impact the selection of remedial alternatives for the Phase IA Business Park. This list of potential action-specific SCGs is based on the candidate remedial alternatives identified in Section 10.

0071-010-350 38

8.4 Future Use Evaluation In developing and screening remedial alternatives, NYSDEC’s Part 375 regulations

require that the reasonableness of the anticipated future land use be factored into the evaluation. The regulations identify 16 criteria that must be considered. These criteria and the resultant outcome for the Phase IA Business Park are presented in Appendix H. As indicated, the evaluation supports commercial and/or industrial redevelopment as the reasonably anticipated future use of the Site, consistent with surrounding Site use, zoning, and the Master Redevelopment Plan endorsed by Tecumseh, Erie County, and the City of Lackawanna. The remedial alternatives identified in Section 10 are evaluated against their consistency with the reasonably anticipated land use as well as other screening criteria.

In addition to the evaluation of alternatives to remediate to the likely end use of the Site, NYSDEC regulation and policy calls for evaluation of an unrestricted use scenario (considered under 6NYCRR Part 375-2.8 to be representative of cleanup to pre-disposal conditions). Per NYSDEC DER-10 Technical Guidance for Site Investigation and Remediation (Ref. 3), evaluation of a “no-action” alternative is also required to provide a baseline for comparison against other alternatives.

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 39

9.0 VOLUME, NATURE, AND EXTENT OF CONTAMINATION Estimation of the volume, nature, and extent of media that may require remediation to

satisfy the RAOs or that needs to be quantified to facilitate evaluation of remedial alternatives is presented in this section. The estimates are a function of the cleanup goal. For the unrestricted use scenario, the cleanup goal would involve achieving USCOs, whereas for the reasonably anticipated future use scenario, the cleanup goal would involve achieving the CSCOs. The volume and extent of media requiring cleanup under these scenarios is presented in Sections 9.1 and 9.2. In addition, the volume and extent of “hotspot” material that may need to be addressed to achieve the RAO for remediation of these areas is discussed in Section 9.3. In all instances, these volume estimates (and associated cost estimates presented later in this AAR) are projected based on limited data and observations collected during the RI; additional pre-remedial investigation would be required to refine the estimates, particularly for hotspot areas.

9.1 Comparison to USCOs Exceedance of the USCOs was noted in many surface and subsurface soil/fill samples

collected, primarily for PAHs (petroleum SVOCs) and metal COCs (i.e., arsenic, cadmium, chromium, lead, and mercury). Due to the highly ubiquitous nature of the constituents observed in Site soil/fill and the extent to which they exceed the USCOs, it is likely that the entire 12.31-acre property defines the impacted soil/fill area. The depth of impact is assumed to extend into native material, with an average depth of approximately 8 fbgs. Thus, the volume of impacted soil/fill requiring remediation is approximately 126,500 cubic yards (CY).

9.2 Comparison to CSCOs The soil/fill data indicated exceedance of the Part 375 CSCOs for several ubiquitous

constituents. Specifically, nearly all samples collected exhibited an exceedance of the CSCO for total arsenic, with several samples also exceeding CSCOs for one or more of the PAHs. Based on these widespread exceedances it is likely that the volume of impacted soil/fill requiring remediation to achieve CSCOs is identical to that calculated above (i.e., approximately 126,500 CY).

9.3 Hotspot Soil/Fill As discussed in Section 8.1, certain surface soil and test pit locations contained elevated

levels of COCs, with three locations corroborated by visual impacts. Figure 5 identifies the location of the impacted areas; except for Hotspot C, the dimensions of each area are approximated since the extent has not been fully defined. The estimated areal and vertical extent of impact in these source areas is described below. These volumes will be confirmed during remedial activities.

Hotspot A – Test Pit BP1A-TP-9: Petroleum product was observed floating on the groundwater at approximately 6 fbgs, together with strong petroleum-like odor. Exploratory test pits near BP1A-TP-9 were excavated to determine the extent of visually impacted fill material. The extent of impact is estimated to be a 15-foot x 45-foot area by 8 feet deep, for a corresponding in-place volume of approximately 200 CY. Accounting for contingency and excavation inefficiencies, the volume for ex-situ treatment and/or disposal alternatives is estimated to be 300 CY. Based on the TCLP data, the soil/fill is considered non-hazardous. Since the depth to water is approximately 6 fbgs, groundwater management may be required.

Hotspot B – Test Pits BP1A-TP-10, BP1A-TP-11 & BP1A-TP-12: A visually impacted layer of fill material was observed in the upper 2 feet at test pit locations BP1A-TP-10 (tar-like) and BP1A-TP-11 (petroleum-like). Subsurface test pit samples collected from BP1A-TP-11 (0.5-3.0 fbgs) and BP1A-TP-12 (0.5-6.0 fbgs) exhibited elevated concentrations of PAHs (above 500 pm). Mercury was also detected at slightly elevated concentrations in each test pit. Absent further delineation of the extent of the impact, an estimated 50-foot x 80-foot area to 6 fbgs has been assumed, for a corresponding in-place volume of approximately 890 CY. Accounting for contingency and excavation inefficiencies, the volume for ex-situ treatment and/or disposal alternatives is estimated to be 1,335 CY. Since the depth to water is approximately 6 fbgs, groundwater management will not likely be required.

Hotspot C – Test Pit BP1A-TP-7: This test pit exhibited elevated concentrations of PAHs in the subsurface soil from the 0.5 to 5.5 fbgs interval. An estimated 20-foot x 20-foot x 6-foot area of impact has been assumed, for a corresponding in-place volume of approximately 90 CY. Accounting for contingency and excavation inefficiencies, the volume for ex-situ treatment and/or disposal alternatives is estimated to be 135 CY. Further delineation of the extent of the impact will be required at this location.

Hotspot D – Surface Soil SS-03: This historic surface soil sample exhibited elevated concentrations of PAHs, as well as lead slightly above the CSCO. An estimated 20-foot x 20-foot x 2-foot area has been assumed, for a corresponding

Page 48: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 41

in-place volume of approximately 30 CY. Accounting for contingency and excavation inefficiencies, the volume for ex-situ treatment and/or disposal alternatives is estimated to be 45 CY. Further delineation of the extent of the impact will be required at this location.

Hotspot E, F, & G – Surface Soils SS-09, SS-10, & SS-11: These sample locations exhibited elevated concentrations of arsenic (SS-09 above its site-specific SCO), cadmium (SS-11 above its ISCO), lead, and mercury in the shallow soil/fill. An estimated 20-foot x 20-foot area with a depth of 2 fbgs has been assumed for each location, for a corresponding in-place volume of approximately 30 CY per location. Accounting for contingency and excavation inefficiencies, the volume for ex-situ treatment and/or disposal alternatives is estimated to be 45 CY per location.

Hotspot H – BP1A-TP-2: An elevated arsenic concentration was detected in the 0.5-3.5 fbgs sample in test pit BP1A-TP-2. Absent further delineation, an estimated 20-foot x 20-foot area has been assumed. Although the elevated arsenic is likely present in the upper 2 feet, a 4-foot depth has been assumed. The corresponding in-place volume is approximately 60 CY. Accounting for contingency and excavation inefficiencies, the total volume for ex-situ treatment and/or disposal alternatives is estimated to be 90 CY.

Based on the estimated and assumed extent of the impacts described above, the total estimated in-place volume of hotspot contamination is 1,360 CY. The volume of soil/fill for ex-situ treatment and/or disposal alternatives is estimated to be 2,040 CY.

10.0 DEVELOPMENT AND SCREENING OF REMEDIAL ALTERNATIVES

10.1 Development of Alternatives The following remedial alternatives have been developed in accordance with the

General Response Actions and NYSDEC regulation and policy:

Alternative 1: No Action

Alternative 2: Unrestricted-Use (Track 1) Cleanup

Alternative 3: Restricted-Use (Track 4) Cleanup with Placement of Soil Cover System Prior to Site Redevelopment

Alternative 4: Restricted-Use (Track 4) Cleanup with Deferred Soil Cover System during Site Redevelopment

Institutional controls, though identified in the General Response Actions, were not identified as a stand-alone remedial alternative because a deed restriction prohibiting use of groundwater and limiting land reuse to industrial and similar non-residential settings already exists for the larger Tecumseh property. Accordingly, all alternatives inherently include these institutional controls. Similarly, all alternatives, except for the “no action” alternative, will include removal of the floor areas where surfaces remain above 10 ug/100 cm2 PCBs. In addition, Alternatives 3 and 4 will require development and enforcement of a Site Management Plan (see Section 11.2). Other institutional and engineering controls that would be considered applicable for this Site and would be incorporated into the remedial alternatives are described in greater detail in Section 11.2.1.

10.2 Evaluation of Alternatives NYSDEC’s Brownfield Cleanup Program calls for remedy evaluation in accordance

with DER-10 Technical Guidance for Site Investigation and Remediation (Ref. 3). In addition to achieving RAOs, the remedial alternatives are evaluated against the following criteria consistent with 6NYCRR Part 375-1.8(f):

Overall Protection of Public Health and the Environment. This criterion is an evaluation of the remedy’s ability to protect public health and the environment, assessing how risks posed through each existing or potential pathway of exposure

Page 50: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 43

are eliminated, reduced, or controlled through removal, treatment, engineering controls, or institutional controls.

Compliance with Standards, Criteria, and Guidance (SCGs). Compliance with SCGs addresses whether a remedy will meet applicable environmental laws, regulations, standards, and guidance.

Long-Term Effectiveness and Permanence. This criterion evaluates the long-term effectiveness of the remedy after implementation. If wastes or treated residuals remain on-site after the selected remedy has been implemented, the following items are evaluated: (i) the magnitude of the remaining risks (i.e., will there be any significant threats, exposure pathways, or risks to the community and environment from the remaining wastes or treated residuals), (ii) the adequacy of the engineering and institutional controls intended to limit the risk, (iii) the reliability of these controls, and (iv) the ability of the remedy to continue to meet RAOs in the future.

Reduction of Toxicity, Mobility, or Volume with Treatment. This criterion evaluates the remedy’s ability to reduce the toxicity, mobility, or volume of Site contamination. Preference is given to remedies that permanently and significantly reduce the toxicity, mobility, or volume of the wastes at the Site.

Short-Term Impacts and Effectiveness. Short-term effectiveness is an evaluation of the potential short-term adverse impacts and risks of the remedy upon the community, the workers, and the environment during construction and/or implementation. This includes a discussion of how the identified adverse impacts and health risks to the community or workers at the Site will be controlled, and the effectiveness of the controls. This criterion also includes a discussion of engineering controls that will be used to mitigate short term impacts (i.e., dust control measures), and an estimate of the length of time needed to achieve the remedial objectives.

Implementability. The implementability criterion evaluates the technical and administrative feasibility of implementing the remedy. Technical feasibility includes the difficulties associated with the construction and the ability to monitor the effectiveness of the remedy. For administrative feasibility, the availability of the necessary personnel and material is evaluated along with potential difficulties in obtaining specific operating approvals, access for construction, etc.

Cost-Effectiveness. Capital, operation, maintenance, and monitoring costs are estimated for each remedial alternative and presented on a present worth basis. Detailed cost estimates for each alternative, excluding the no action alternative, are presented on Tables 14 through 16.

Community Acceptance. This criterion evaluates the public’s comments, concerns, and overall perception of the remedy. The Community Acceptance criterion incorporates public concerns into the evaluation of the remedial

Page 51: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 44

alternatives. Therefore, Community Acceptance of the remedy will be evaluated after the public comment period required by the BCP.

Land Use. In addition to the above criteria, 6NYCRR Part 375-1 specifies that the criterion of Land Use (i.e., the current, intended, and reasonably anticipated future land uses of the Site and its surroundings) be considered in the selection of the remedy. The intended future land use was initially submitted to the NYSDEC via the BCP application. The reasonably anticipated future use of the Site in a commercial/industrial capacity (i.e., as a business park) is further discussed in Appendix H.

Alternative 1: No Action The no-action alternative is defined as taking no additional actions to address the

impacted soil/fill. The Site is presently subject to a deed restriction prohibiting groundwater use and limiting reuse to industrial and similar non-residential settings; the Site is fenced along NYS Route 5. While these controls would not be removed, the no action alternative assumes that there would be no maintenance, monitoring, or certifications to assure that these controls remain in place and effective. The no-action alternative also provides a baseline for comparison against the other remedial alternatives and justifies the need for any remedial action.

Overall Protection of Public Health and the Environment – This alternative would

protect public health under the current use scenario via the existing engineering and institutional controls; however, localized areas of environmental impact associated with hotpot areas would remain. This alternative would not meet the RAOs for the Site.

Compliance with SCGs – This alternative would not address source area materials or

mitigate exposure to contaminants above SCOs and would therefore not comply with SCGs per 6NYCRR Part 375.

Long-Term Effectiveness and Permanence – This alternative provides no long-

term maintenance measures and, as such, provides no reliable long-term control against exposure to impacted soil/fill. All current and future risks would remain under this alternative.

Page 52: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 45

Reduction of Toxicity, Mobility, or Volume with Treatment – This alternative provides no reduction in toxicity, mobility, or volume of COCs in soil/fill.

Short-Term Impacts and Effectiveness – There would be no additional risks posed

to the community, Site workers, or the environment associated with implementation of this alternative.

Implementability – No technical implementability issues or action-specific

administrative implementability issues are associated with this alternative. Cost-Effectiveness – There are no capital or operation, maintenance, and monitoring

costs associated with this alternative. Land Use – This alternative is consistent with the reasonably anticipated future use of

the Site but would not promote commercial and industrial redevelopment due to the absence of a release from liability and placement of the responsibility to assure protection of public health following redevelopment on the future buyer or developer.

Alternative 2: Unrestricted-Use (Track 1) Cleanup For unrestricted use scenarios, excavation and off-site treatment or disposal of

impacted soil/fill would be performed, obviating the need for engineering and institutional controls. This alternative would necessitate excavation of all soil/fill where COCs exceed USCOs per 6NYCRR Part 375, with transport of the excavated materials to and disposal at a permitted, off-site disposal facility. The estimated total volume of impacted soil/fill that would be removed from the Site and disposed off-site is approximately 126,500 CY. The same volume of clean soil would be necessary to backfill the excavation. For purposes of cost estimating, all excavated materials are assumed to be non-hazardous and would be transported to a commercial solid waste disposal facility. Previous experience during test pit excavations indicates the material is well-drained; however, provisions for managing groundwater will be in place.

Alternative 2 would also require removal of low-contact impervious surfaces with PCB concentrations above 10 ug/m2 in the Power House No. 1 Building.

Page 53: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 46

Overall Protection of Public Health and the Environment – Excavation and off-

site disposal to USCOs would be protective of public health under any reuse scenario. However, this alternative would permanently use and displace 126,500 CY of valuable landfill airspace, causing ancillary environmental issues due to reduced landfill capacity, and would require removal of 126,500 CY of clean soil from an off-site borrow source, also contributing to significant detrimental off-site environmental issues. Removing the PCB-impacted floor surfaces will mitigate any potential exposure.

Compliance with SCGs – Excavation and off-site soil/fill disposal as well as removal

of PCB-impacted floor surfaces would need to be performed in accordance with applicable, relevant, and appropriate SCGs. Soil excavation activities would necessitate preparation of and adherence to a community air monitoring plan for particulates in accordance with Appendix 1B of DER-10.

Long-Term Effectiveness and Permanence – This alternative would achieve

removal of all impacted soil/fill and potential for contact with PCB-impacted floor surfaces thereby providing long-term effectiveness and permanence. Post-remedial monitoring and certifications would not be required.

Reduction of Toxicity, Mobility, or Volume with Treatment – Through removal

of all impacted soil/fill and PCB-impacted floor surfaces, this alternative would permanently and significantly reduce the toxicity, mobility, and volume of contamination on the Site. However, since this alternative transfers Site soil/fill from one environment to another, an overall reduction of toxicity, mobility, and volume would not occur.

Short-Term Impacts and Effectiveness – The short-term adverse impacts and risks

to the community, workers, and environment during implementation of this alternative are significant. Site workers would be required to wear personal protective equipment (PPE) during excavation to prevent direct contact with soil/fill and PCB-impacted concrete. Dust control methods would be required to limit the release of particulates during placement of the backfill soils. Physical hazards, primarily related to potential accidents from heavy truck traffic

Page 54: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 47

on NY State Route 5, would be expected. Substantial disruption of the neighboring community would occur due to material transport and deliveries and noise from heavy equipment used to construct the remedy. The Remedial Action Objectives would be achieved once the soil/fill is removed from the Site and backfill soils are in place (est. 1 year).

Implementability – Significant technical and administrative implementability issues

would be encountered in construction of this unrestricted use alternative. These include but are not limited to the need for construction, maintenance, and operation of substantial dewatering facilities; and traffic coordination for trucks entering/exiting NY State Route 5.

Cost-Effectiveness – Capital costs for implementation of this alternative are

estimated at $15.6 million. There are no operation and maintenance costs associated with this alternative. Table 14 presents a breakdown of these capital costs.

Land Use – This alternative, although inconsistent with the reasonably anticipated

future use of the Site, would not preclude commercial and industrial redevelopment.

Alternative 3: Restricted-Use (Track 4) Cleanup with Placement of Soil Cover System Prior to Redevelopment

This alternative would initially involve removal of the eight hotspot areas described in Section 9.3. The petroleum-impacted soil/fill (Hotspots A and C) would likely be treated via on-site bioremediation (e.g., on a biopad constructed in Business Park IA) with relocation of the treated soils back into the excavation area. Since product was observed on the water at approximately 6 fbgs in test pit BPIA-TP-9 (Hotspot A), water encountered during excavation will be collected, if visually impacted, and treated prior to surface discharge. To address residual smear zone soil/fill impacts in Hotspot A, a chemical amendment such as oxygen release compound (ORC) or ORC Advanced will be mixed into the saturated soils at the bottom of the excavation prior to backfilling to enhance subsequent in-situ aerobic bioremediation of saturated soils and localized groundwater. The remaining hotspot soil/fill areas, containing metals and/or petroleum with metals, are assumed to be non-hazardous and would be excavated and disposed off-site at a permitted solid waste disposal facility. If during remedial actions, soil/fill fails TCLP then the soil/fill would be stabilized in-place using an

Page 55: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 48

amendment such as Portland cement. Previous experience during test pit excavations indicates the material is well-drained; however, if necessary, groundwater will be collected, treated via filtration and granular activated carbon (GAC), and discharged to an on-site soil surface with NYSDEC approval.

Like Alternative 2, this alternative also includes removal of low-contact impervious surfaces with PCB concentrations above 10 ug/m2 in the Power House No. 1 Building with off-site disposal.

Following hotspot soil/fill removal, a 12-inch soil cover would be installed over the approximate 8 acres not covered by buildings, concrete slabs, or competent asphalt prior to Certificate of Completion issuance and redevelopment. The estimated total volume of clean soil required for the cover system is approximately 12,900 CY. The cover would then be removed, as necessary, to accommodate build-out during the redevelopment period. Standard institutional and engineering controls would also be implemented under this alternative. Specifically, a Site Management Plan (SMP) incorporating an Excavation Plan; an Operation, Maintenance, and Monitoring (OM&M) Plan; and ongoing Engineering and Institutional Control certification requirements would be developed and enforced through an environmental easement. The environmental easement will restrict use of the Phase IA Business Park to commercial and industrial applications and preclude groundwater use without treatment.

Overall Protection of Public Health and the Environment – Removing the hotspot

soil/fill, treating impacted water, applying an amendment, and removing the PCB-impacted floor surfaces, followed by cover system placement will mitigate any potential exposure. This alternative meets NYSDEC requirements for a Track 4 cleanup under the BCP regulations and is therefore protective of public health and the environment at the Site. Accordingly, Alternative 3 would achieve the RAOs. However, placement of a 12-inch soil cover over 8 acres of the Phase IA Business Park would require immediate clearing of the Site and borrow source(s), resulting in rapid loss of 8 acres of greenhouse gas consuming plant life and cover for habitat and foraging on-site and a likely similar acreage off-site, which is inconsistent with NYSDEC’s DER-31 green remediation policy (Ref. 7). In addition, significant short-term impacts would result from implementation of this alternative as described below.

Page 56: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 49

Compliance with SCGs – Excavation and off-site soil/fill disposal, on-site biotreatment of petroleum-impacted soil/fill, and removal of PCB-impacted floor surfaces would need to be performed in accordance with applicable, relevant, and appropriate SCGs. Imported cover material would need to meet backfill quality criteria per 6NYCRR Part 375. Borrow source mining would require a permit and storm water pollution prevention plan (SWPPP) for all disturbed areas greater than 1 acre in size. Vegetative cover stripping and cover placement would be performed under the BCP and would therefore require an equivalent SWPPP to address on-site impacts. Subgrade preparation activities would necessitate preparation of and adherence to a community air monitoring plan for fugitive dust and particulate monitoring in accordance with Appendix 1B of DER-10. As indicated above, this alternative is inconsistent with NYSDEC’s DER-31 green remediation policy due to rapid loss of vegetative cover on the site and off-site, as well as significant air emissions attributable to use of heavy diesel equipment for excavation and transport onsite and at the borrow source.

Long-Term Effectiveness and Permanence – Removal of the hotspot soil/fill areas,

treatment of excavation water and smear zone soil/fill in Hotspot A, and removal of PCB-impacted floor surfaces as well as construction of a cover system prior to redevelopment would prevent direct contact with soil/fill exceeding CSCOs. The efficacy of the cover system will be maintained and monitored via the Site Management Plan. Periodic inspection and maintenance of the cover and possible repair of the soil and vegetative layers would be required to assure long-term cover integrity. The institutional controls outlined in Section 11 would be required for long-term effectiveness.

Reduction of Toxicity, Mobility, or Volume with Treatment – Bioremediation of

hotspot soil/fill would permanently and significantly reduce the toxicity, mobility, and volume of the soil/fill that could potentially be contacted or produce localized areas of environmental impact at the Site. Treatment of impacted excavation water and in situ treatment of smear zone soil/fill would reduce the toxicity, mobility, and volume of contamination. Excavation and off-site disposal of the metal-impacted soil/fill would reduce the toxicity, mobility, and volume of impacted soil/fill on-site; however, since this alternative transfers Site soil/fill from one environment to another, an overall reduction of toxicity and volume would not occur. Placement of a soil cover over the remaining areas would somewhat reduce the mobility of

Page 57: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 50

contaminants from erosion, although the RI concluded that this pathway is not likely significant under the current (undeveloped) scenario. Accordingly, the toxicity, mobility, and volume of remaining residual contaminants would not be appreciably reduced under this alternative. Removal of PCB-impacted floor surfaces would permanently reduce the toxicity, mobility, and volume of PCB contamination on the Site.

Short-Term Effectiveness and Impacts – Similar to Alternative 2, the short-term

adverse impacts and risks to the community, workers, and environment during implementation of this approach are significant. Because Site clearing and soil cover placement would occur in a single construction season as opposed to a gradual progression during build out, immediate disruption of wildlife habitat would occur due to material transport, deliveries, noise, and air emissions from heavy equipment used to strip the site and construct the cover.

Moreover, under this alternative, the Phase IA Business Park would require over 12,900 CY of imported cover soil, which would be stripped from an off-site borrow source and then transported to the Site in approximately 920 truckloads and graded/raked using heavy, diesel-fueled grading equipment. This action alone would result in storm water impacts at the borrow source(s) and on-site; diesel fuel consumption on the order of 2,300 gallons (assuming 20 miles round trip, 8 miles per gallon); and related traffic, dust, and air emissions. These impacts would be compounded when redevelopment is initiated, as much of the soil cover (est. 80%) would need to be removed and hauled off-site to allow for build out. Thus, an additional 1,840 gallons of diesel fuel may be consumed, resulting in total consumption of approximately 4,140 gallons of diesel fuel for transportation, with additional consumed by excavation and grading equipment. The USEPA’s estimated CO2 generation rate for diesel engines is approximately 22.2 pounds per gallon of diesel consumed. Accordingly, the transportation of soil cover to the Site and subsequent removal and off-site transportation would produce approximately 91,900 pounds of greenhouse gas while at the same time stripping hundreds of acres of CO2 consuming trees and shrubs.

Finally, the existing soil/fill currently allows for good surface water percolation and drainage. If a soil cover were placed over the Phase IA Business Park ahead of redevelopment, it would be absent the permanent storm water drainage system and Site grading that will be designed and constructed when redevelopment occurs. As a result, ponding, washout, and undesirable drainage patterns can be expected, damaging the cover system if soil cover is

Page 58: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 51

placed before final grading and storm water collection and conveyance systems are in place. The RAOs would be achieved upon cover placement.

Implementability – Technical implementability issues anticipated under this

alternative include traffic coordination for trucks entering and exiting NY State Route 5 and the need to design and provide for significant erosion and storm water controls to mitigate ponding, washout, and undesirable storm water drainage and runoff patterns. A pre-redevelopment cover system is also certain to be damaged and repaired multiple times by development work and buried infrastructure (sewer, water, gas, electric, telephone, etc.), necessitating multiple inspections by an environmental professional, and documentation/ explanation in annual Periodic Review Reports.

No significant administrative implementability issues are associated with this alternative.

Cost-Effectiveness – The estimated capital cost for this alternative is $1.0 million,

including hotspot removal, bioremediation, and off-site disposal; treatment of Hotspot A water and application of amendment; removal of PCB-impacted floor surfaces; construction of the 12-inch landscape cover over an approximate 8 acres; development of a Site Management Plan; and environmental-based redevelopment costs associated with removal of the temporary soil cover system. Annual OM&M costs for cover maintenance and annual certifications are estimated to be $24,000, resulting in an estimated 30-year present worth cost of $1.8 million. Table 15 presents a breakdown of these costs.

Land Use – This alternative would be consistent with the reasonably anticipated future

use of the Site. However, the placement of soil cover over the Site would significantly impair the ability and cost of redeveloping the Site. Redevelopment would require the removal and displacement of most if not all soil cover during infrastructure and building construction, would necessitate deeper excavation to access existing for utilities, and would limit the ability to locate existing foundations and other near-surface structures that may require removal during redevelopment.

Page 59: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 52

Alternative 4: Restricted-Use (Track 4) Cleanup with Deferred Cover System during Site Redevelopment

This alternative is the same as Alternative 3 in that it provides for construction of a 12-inch soil cover over exposed areas of the Site following hotspot soil/fill removal and in-situ treatment of saturated soil/fill in Hotspot A; however, the cover would be placed during the redevelopment stage to coordinate with and exclude the cover that inherently will be provided by building, road, parking areas and landscaping. COC issuance would occur following cover placement. A Site Management Plan and environmental easement (see Section 11) would be prepared.

Alternative 4 also includes removal of the low-contact impervious surfaces with PCB concentrations above 10 ug/m2 in the Power House No. 1 Building.

Overall Protection of Public Health and the Environment – Based on the removal

of PCB-impacted floor surfaces; removal of hotspot soil/fill; treatment of impacted water in Hotspot A and application of an amendment like ORC; and the fact that the Site is isolated, covered by indigenous vegetation, secured with fencing, and patrolled by security during off hours to discourage trespassing, this alternative is protective of public health and the environment under the current (undeveloped) remediated scenario. This alternative would be protective of public health and the environment under the future use scenario, as it provides for implementation of the 12-inch cover system in areas not otherwise covered by buildings, roads, etc. Therefore, Alternative 4 successfully achieves the RAOs for the Site.

Compliance with SCGs – Excavation and off-site soil/fill disposal, on-site

biotreatment of petroleum-impacted soil/fill, and removal of PCB-impacted floor surfaces would need to be performed in accordance with applicable, relevant, and appropriate SCGs. Imported cover material would need to meet backfill quality criteria per 6NYCRR Part 375. Borrow source mining would require a permit and SWPPP for all disturbed areas greater than 1 acre in size. Vegetative cover would be placed during the redevelopment period along with building, road, and other build-out and as such would be subject to storm water regulations. Soil excavation and cover activities would necessitate preparation of and adherence to a community air monitoring plan for fugitive dust and particulate monitoring in accordance with Appendix 1B of DER-10.

Page 60: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 53

Long-Term Effectiveness and Permanence – Removal of the hotspot soil/fill,

treatment of excavation water and smear zone soil/fill in Hotspot A, and removal of PCB-impacted floor surfaces as well as construction of a cover system prior to occupancy would prevent direct contact with soil/fill exceeding CSCOs. The efficacy of the cover system will be maintained and monitored via the Site Management Plan. Periodic inspection and maintenance of the soil cover as well as the “hardscape” cover provided by asphalt roads, concrete, etc. would be required to assure long-term cover integrity. The institutional controls outlined in Section 11 would be required for long-term effectiveness.

Reduction of Toxicity, Mobility, or Volume with Treatment – Bioremediation of

hotspot soil/fill would permanently and significantly reduce the toxicity, mobility, and volume of the soil/fill that could potentially be contacted or produce localized areas of environmental impact at the Site. Treatment of impacted excavation water and in situ treatment of smear zone soil/fill would reduce the toxicity, mobility, and volume of contamination. Excavation and off-site disposal of the metal-impacted soil/fill would reduce the toxicity, mobility, and volume of impacted soil/fill on-site; however, since this alternative transfers Site soil/fill from one environment to another, an overall reduction of toxicity and volume would not occur. Placement of a soil cover in conjunction with cover provided by build-out over the remaining areas may somewhat reduce the mobility of contaminants from erosion, although the RI concluded that this pathway is not likely significant under the current (undeveloped) scenario. Accordingly, the toxicity, mobility, and volume of remaining residual contaminants would not be appreciably reduced under this alternative. Removal of PCB-impacted floor surfaces would permanently reduce the toxicity, mobility, and volume of PCB contamination on the Site.

Short-Term Impacts and Effectiveness – Because cover will be placed on a gradual

basis as development occurs and will exclude hardscape cover inherently provided by buildings, roads, parking areas, etc. (which are anticipated to represent 50% of the Site acreage), short-term impacts will be minimized. As the cover soil placement will coordinate with the build-out, no additional removal work will be required. Community air monitoring, dust control, and soil erosion measures would only be required during Site development. The RAOs would be achieved upon cover placement.

Page 61: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 54

Implementability – No significant technical or administrative implementability issues

are anticipated under this alternative. Cost-Effectiveness – The estimated capital cost for this alternative is $813,000

including hotspot soil/fill removal, bioremediation, and off-site disposal; treatment of Hotspot A water and application of an amendment for treatment of saturated soil/fill in Hotspot A; removal of PCB-impacted floor surfaces; cover system construction during remediation (i.e., areas not covered by building, parking, or roads, assumed to be approximately 50% of the Site); development of a Site Management Plan; and environmental-based redevelopment costs associated with engineering oversight and air monitoring during intrusive work. Annual OM&M costs for cover maintenance and annual certifications are estimated to be $24,000, resulting in an estimated 30-year present worth cost of $1.5 million. Table 16 presents a breakdown of these costs.

Land Use – This alternative is consistent with the reasonably anticipated future use of

the Site. Furthermore, this alternative facilitates redevelopment by deferring final soil cover placement until redevelopment, thus avoiding the costs, time delays, and unnecessary disruption of placing, removing, and replacing cover during building, road, and utility construction.

10.3 Proposed Remedy The previous sections describe the remedial alternatives and evaluate these alternatives

against the screening criteria. This final section of the evaluation considers the information and evaluations contained in the previous sections to identify appropriate remedial measures to achieve the RAOs for the Phase IA Business Park.

The proposed remedial approach for the impacted soil/fill is Alternative 4 – Restricted-Use (Track 4) Cleanup with Deferred Cover System During Redevelopment because it satisfies the RAOs for the Site, is significantly less disruptive to the community, is consistent with current and future land use, and represents a lower cost than Alternatives 2 and 3. This alternative would involve removal of eight hotspot areas described in Section 9.3 followed by off-site disposal or on-site biotreatment of soil/fill. An estimated 2,040 CY of impacted soil/fill would be

Page 62: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 55

excavated (although confirmation of this volume would occur prior to or during remedy implementation). This alternative would also include treatment of Hotspot A water and in-situ treatment of residual impacts to saturated soil/fill following removal of Hotspot A, and removal of the remaining area of the floor impacted by PCBs. Regulated building materials, including residual asbestos containing material and fallen or deteriorated lead-based paint, if present, would be property abated and disposed off-site in accordance with NYS Department of Labor and NYSDOH requirements. If present, water in the Power House No. 1 basement will be pumped, characterized, and, if appropriate, treated with GAC and discharged to soil surface with NYSDEC approval.

As a condition of occupancy, the Site developer/owner would be required to cover all soil/fill areas that exceed the CSCOs with asphalt, building, or landscape cover. The landscape cover would involve placement of at least one foot of clean soil followed by seeding to promote vegetative growth. The clean soil would be required to meet NYSDEC DER-10 standards for commercial sites (i.e., lower of Part 375 human health or groundwater protection values).

The 30-year present worth cost is estimated to be $1.5 million with a projected $813,000 for capital expenditures and $24,000 for annual Site maintenance and environmental easement certification.

11.0 POST-REMEDIAL REQUIREMENTS

11.1 Final Engineering Report Following completion of the hotspot area remedial measures, a Construction

Completion Report (CCR) documenting the cleanup activities and an associated Site Management Plan (SMP) and easement will be prepared for the Phase IA Business Park Site. A Final Engineering Report (FER) will be submitted to the NYSDEC once cover is placed. The FER will refer to the CCR and will include the following information and documentation, consistent with the NYSDEC regulations contained in 6 NYCRR Part 375-1.6(c):

Background and Site description.

Certification by a professional engineer to satisfy the requirements outlined in 6 NYCRR Part 375-1.6(c)(4).

Description of engineering and institutional controls at the Site.

Site map showing the areas remediated.

Documentation of imported materials.

Documentation of materials disposed off-site.

Copies of daily inspection reports and, if applicable, problem identification and corrective measure reports.

Air monitoring data and reports.

Photo documentation of remedial activities.

Text describing the remedial activities performed; a description of any deviations from the Work Plan and associated corrective measures taken; and other pertinent information necessary to document that the site activities were carried out in accordance with this Work Plan.

Analytical data packages and data usability summary reports (DUSRs).

11.2 Site Management Plan A Site Management Plan (SMP) will be prepared and submitted concurrent with the

FER. The purpose of the Site Management Plan is to assure that proper procedures are in

place to provide for long-term protection of human health and the environment after remedial construction is complete. The SMP is comprised of four main components:

Engineering and Institutional Control Plan

Site Monitoring Plan

Operation and Maintenance Plan

Inspections, Reporting, and Certifications

Engineering and Institutional Control Plan An institutional control in the form of a new Environmental Easement will be

necessary to limit future use of the Site to restricted (commercial or industrial) applications and prevent groundwater use for potable purposes. An existing deed restriction is on file for the Tecumseh Site limiting reuse to commercial/industrial applications. However, industrial uses are loosely defined and allow incidental commercial-type facilities such as offices and laboratories, provided they do not allow for occupancy by multiple numbers of persons under the age of 18. The deed restriction also prohibits construction or use of groundwater extraction wells (excluding monitoring and remediation wells).

Tecumseh will prepare an Engineering and Institutional Control (EC/IC) Plan that will include a complete description of all institutional and/or engineering controls employed at the Site, including the mechanisms that will be used to continually implement, maintain, monitor, and enforce such controls. The EC/IC Plan will include:

A description of all EC/ICs on the site.

The basic implementation and intended role of each EC/IC.

A description of the key components of the ICs set forth in the Environmental Easement.

A description of the features to be evaluated during each required inspection and periodic review, including the EC/IC certification, reporting, and Site monitoring.

A description of plans and procedures to be followed for construction of the 12-inch soil cover as a condition of occupancy.

Any other provisions necessary to identify or establish methods for implementing the EC/ICs required by the Site remedy, as determined by the NYSDEC.

Site Monitoring Plan The Site Monitoring Plan will describe the measures for evaluating the performance

and effectiveness of the remedy to reduce or mitigate contamination at the Site, including:

Sampling and analysis of all appropriate media.

Assessing compliance with NYSDEC standards, criteria, and guidance, particularly Part 375 SCOs for soil.

Assessing achievement of the remedial performance criteria.

Evaluating site information periodically to confirm that the remedy continues to be effective in protecting public health and the environment; and

Preparing the necessary reports for the various monitoring activities.

To adequately address these issues, this Site Monitoring Plan will provide information on:

Sampling locations, protocol, and frequency.

Information on all designed monitoring systems (e.g., well logs).

Analytical sampling program requirements.

Reporting requirements.

Quality assurance/quality control (QA/QC) requirements.

Inspection and maintenance requirements for monitoring wells.

Monitoring well decommissioning procedures.

Annual inspection and periodic certification.

Operation and Maintenance Plan An Operation & Maintenance (O&M) plan governing maintenance of the cover system

will include:

Include the operation and maintenance activities necessary to allow individuals unfamiliar with the Site to maintain the soil cover system.

Include an O&M contingency plan.

Evaluate Site information periodically to confirm that the remedy continues to be effective for the protection of public health and the environment. If necessary, the

Page 66: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 59

O&M Plan will be updated to reflect changes in Site conditions or the way the cover system is maintained.

Inspections, Reporting, and Certifications

11.2.4.1 Inspections Site-wide inspection will be conducted annually or as otherwise approved by the

NYSDEC. All applicable inspection forms and other records, including all media sampling data and system maintenance reports, generated for the Site during the reporting period will be provided in electronic format in a Periodic Review Report (PRR).

11.2.4.2 Reporting

The PRR will be submitted to the NYSDEC annually, or as otherwise approved, beginning 18 months after the Certificate of Completion or equivalent document is issued. The PRR will be prepared in accordance with NYSDEC DER-10, be submitted within 45 days of the end of each certification period, and include:

Identification, assessment, and certification of all EC/ICs required by the remedy for the Site.

Results of the required annual Site inspections and severe condition inspections, if applicable.

All applicable inspection forms and other records generated for the Site during the reporting period in electronic format.

Data summary tables and graphical representations of contaminants of concern by media, which include a listing of all compounds analyzed, along with the applicable standards, with all exceedances highlighted. These will include a presentation of past data as part of an evaluation of contaminant concentration trends.

Results of all analyses, copies of all laboratory data sheets, and the required laboratory data deliverables for all samples collected during the reporting period will be submitted electronically in a NYSDEC-approved format.

A Site evaluation that includes the following:

- The compliance of the remedy with the requirements of the site-specific RAWP, ROD, or Decision Document.

- The operation and the effectiveness of all treatment units, etc., including identification of any needed repairs or modifications.

Page 67: REMEDIAL INVESTIGATION/ ALTERNATIVES ANALYSIS …

RI/AA REPORT PHASE IA BUSINESS PARK

0071-010-350 60

- Any new conclusions or observations regarding site contamination based on inspections or data generated by the Site Monitoring Plan for the media being monitored.

- Recommendations regarding any necessary changes to the remedy and/or Site Monitoring Plan.

- The overall performance and effectiveness of the remedy.

11.2.4.3 Certification

The signed EC/IC Certification will be included in the PRR described in Section 11.2.4.2: For each institutional or engineering control identified for the Site, a Professional Engineer licensed to practice in New York State will certify that all of the following statements are true:

The inspection of the Site to confirm the effectiveness of the institutional and engineering controls required by the remedial program was performed under my direction.

The engineering and institutional controls employed at this Site are unchanged from the date the control was put in place, or last approved by the NYSDEC.

Nothing has occurred that would impair the ability of the control to protect the public health and environment.

Nothing has occurred that would constitute a violation or failure to comply with any Site Management Plan for this control.

Access to the Site will continue to be provided to the NYSDEC to evaluate the remedy, including access to evaluate the continued maintenance of this control.

If a financial assurance mechanism is required under the oversight document for the Site, the mechanism remains valid and sufficient for the intended purpose under the document.

Use of the Site is compliant with the Environmental Easement.

The engineering control systems are performing as designed and are effective.

To the best of my knowledge and belief, the work and conclusions described in this certification are in accordance with the requirements of the Site remedial program and generally accepted engineering practices.

The information presented in this report is accurate and complete.

11.2.4.4 Corrective Measures Plan

If any component of the remedy is found to have failed, or if the periodic certification cannot be provided due to the failure of an institutional or engineering control, a Corrective Measures Plan will be submitted to the NYSDEC for approval. This plan will explain the failure and provide the details and schedule for performing work necessary to correct the failure. Unless an emergency condition exists, no work will be performed pursuant to the Corrective Measures Plan until it is approved by the NYSDEC.

3. Additional SVOCs were detected but at concentrations well below unrestricted use. Samples only analyzed for RCRA Metals.

4. Data qualifiers per third-party Data Usability Summary Report (DUSR)

Acronyms:

ND = Parameter not detected above laboratory detection limit.

" -- " = not analyzed for this parameter or no individual SCO

BOLD = Value exceeds Unrestricted Use SCO

Laboratory Qualifiers (located next to the sample result):

J = Analyte was detected at a level less than the Reporting Limit (RL) and greater than or equal to the Method Detection Limit (MDL). Concentrations within this range are estimated.

D = Dilution required.

ID4 = Benzo(b)fluoranthene coelutes with Benzo(k)fluoranthene. The reported result is a summation of the isomers and the concentration is based on the response factor of Benzo(b)fluoranthene.

B = Analyte was detected in associated Method Blank.

QSU = Sulfur (EPA 3660) clean-up performed on extract.

W1 = Sample was prepared and analyzed utilizing a medium level extraction.

Data Validation Qualifiers (under separate column "Q"):

J = The analyte was positively identified; the associated numerical value is an approximate concentration of the analyte in the sample.

NJ = The detection is tentative in identification and estimated in value. Although there is presumptive evidence of the analyte, the result should be used with caution as a potential false positive and/or elevated quantitative value.

NOTES:

1. The North and South Return Water Trenches are excluded from the Phase IA Business Park site.2. The groundwater contours shown were developed using linear interpolation between groundwater well

water elevations, results of previous groundwater contour maps, and engineering judgement.3. The bottom of the North and South Return Water Trenches are at approximate elevation of 570 feet. It

is believed that when the groundwater elevation proximate to the trenches is above 570 feet, thetrenches are groundwater sinks.
