1.0 INTRODUCTION

Langan Engineering, Environmental, Surveying and Landscape Architecture, D.P.C. (Langan) prepared this Phase II Environmental Site Investigation (ESI) Report, on behalf of Peck Slip Associates LLC, for the property located at 250 Water Street (Block 98, Lot 1) in the South Street Seaport neighborhood of New York (the Site). The Phase II ESI was conducted to investigate potential impacts from Recognized Environmental Conditions (RECs) identified in a Phase I Environmental Site Assessment (ESA), dated September 2015.

The Phase II ESI was implemented on October 3, 2015. NOVA Geophysical Survey (NOVA) completed the geophysical survey and AARCO Environmental Services Corp. (AARCO) advanced soil borings and installed temporary monitoring wells and soil vapor points under the oversight of Langan field engineers.

This report is organized as follows:

Section 2.0: Describes the Site background including a discussion of previous investigations

Section 3.0: Presents the investigation methodology

Section 4.0: Presents the findings

Section 5.0: Presents conclusions



2.0 BACKGROUND

2.1 Site Location and Description

The Site about 47,900 square feet and occupies the entire New York City Tax Block 98 (comprised of a single tax lot: Lot 1) in the South Street Seaport neighborhood of New York. The block is bordered by Pearl Street to the north, Peck Slip to the east, Water Street to the south, and Beekman Street to the west. The Site is occupied by a 400-vehicle capacity commercial parking lot and is improved with a parking attendant kiosk and temporary storage shed. A Site location map is provided as Figure 1.

According to the United States Geological Survey (USGS) Central Park Quadrangle 7.5-minute Series Topographic Map, the Site sits at an elevation of about elevation (el) 10 Borough President of Manhattan Datum (BPMD)1. The Site and surrounding area slope downwards to the southeast toward the East River, which is about 530 feet southeast of the Site. The Site is in an urban area, characterized by residential and commercial buildings.

2.2 Phase I ESA Findings

Langan completed a Phase I ESA of the Site in September 2015. The Phase I ESA identified the following RECs:

1. Historical use of the Site as a factory, an oil company, a printer, a metal works, a mercury and thermometer warehouse, a chemicals and glue company, a chemical company, a trucking company, a thermometer company, a garage with two 550-gallon underground storage tanks (USTs), a machine shop, and a gasoline service station.

2. The presence of historic fill at the Site. 3. Historical use of adjoining and surrounding properties as a metals works, an “oils”

facility, trucking companies, a garage, a machine shop, a printer, a substation, an automobile repair facility, and facilities with petroleum bulk storage.

The Phase I ESA identified de minimis staining from automobile fluids on the asphalt surface of the parking lot; the asphalt surface was observed to be in good condition.

1 Borough President of Manhattan Datum (BPMD) is 2.750 feet above mean sea level at Sandy Hook New Jersey as defined by the

United States Geologic Survey (USGS NGVD 1929).



In addition, the location of the Site within the advisory limit of the 0.2 percent Annual Chance Flood Hazard Area was considered a business environmental risk. A copy of the Phase I is included in Appendix A.

2.3 Regional Geology

Bedrock underlying the property is mapped as Manhattan Schist, which is described as a gray sillimanite-muscovite-tourmaline schist. The Engineering Bedrock Map indicates that bedrock is about 100 to 150 feet below the grade surface (bgs).

According to the Sanitary and Topographical Map of the City and Island of New York created by Egert L. Viele in 1865, the Site is located within a former meadow on the edge of the historical shoreline. Based on Langan’s drilling experience in the area, about 20 feet of historic fill generally overlies native deposits.

2.4 Regional Hydrogeology

Groundwater flow is typically topographically influenced, as shallow groundwater tends to originate in areas of topographic highs and flows toward areas of topographic lows, such as rivers, stream valleys, ponds, and wetlands. A broader, interconnected hydrogeologic network often governs groundwater flow at depth or in the bedrock aquifer. Groundwater depth and flow direction are also subject to hydrogeologic and anthropogenic variables such as precipitation, evaporation, extent of vegetation cover, and coverage by impervious surfaces. Other factors influencing groundwater include depth to bedrock, the presence of artificial fill, and variability in local geology and groundwater sources or sinks. Based on the local topographic gradient and the presence of a nearby surface water body, groundwater is inferred to flow southeast towards the East River. Based on Langan’s drilling experience in the area, groundwater is at about 10 feet bgs.

Groundwater in New York City is not used as a potable water source. Potable water is supplied to Manhattan by the City of New York and is derived from surface impoundments in the Croton, Catskill, and Delaware watersheds. Municipal water is not used on the Site.



3.0 FIELD INVESTIGATION

The Phase II ESI was completed on October 3, 2015 and consisted of the following activities:

A geophysical investigation of the Site to identify potential UST locations and subsurface utilities and anomalies;

Advancement of 10 soil borings and collection of 21 grab soil samples for laboratory analysis;

Installation and sampling of 5 temporary groundwater monitoring wells; and

Installation and sampling of 5 temporary soil vapor points.

3.1 Geophysical Survey

Prior to commencement of invasive field activities, NOVA of Douglaston, New York, conducted a geophysical survey under the oversight of Langan field engineers. The survey included ground penetrating radar (GPR) and electromagnetic (EM) detectors in an attempt to locate and identify current and former utility lines, potential geophysical signature anomalies, USTs, and subsurface structures, and to clear proposed boring locations. A copy of the geophysical survey report is included in Appendix B.

3.2 Soil Investigation

The soil investigation included advancement of ten soil borings (SB1 through SB10) by AARCO under the oversight of Langan field engineers. Prior to the investigation, One-Call was contacted by AARCO, and utilities marked out on the adjacent roadways. The depth of soil borings ranged from 8 to 28 feet bgs. Soil borings were advanced either 3 to 5 feet below groundwater, or to a depth below observed impacts. Boring were advanced with a Geoprobe® 6610DT and a Geoprobe® 7722DT direct-push samplers (in the interest of time, two rigs were deployed simultaneously).

Samples were collected continuously into four-foot Macro-Core® sample barrels lined with dedicated acetate sleeves. Soil samples retrieved from borings were visually classified for soil type, grain size, texture and moisture content. Each sample was screened for visual, olfactory, and instrumental indicators of a potential chemical or petroleum release. Instrument screening for the presence of organic vapors was performed with a photoionization detector (PID) equipped with a 10.6 electron Volt (eV) lamp. Following sample collection, borings were either backfilled with soil cuttings and completed with asphalt patches, or were converted into temporary monitoring wells. Refusal was encountered in soil borings SB3, SB7, SB8, SB9 and



SB10. The boring locations were offset by about 5-feet and a second attempt was made to complete the boring. Sample descriptions of borings SB8 and SB8B (refusal at 8 feet bgs) varied; therefore, the boring log for SB8B is also included in Appendix C.

In general, one soil sample was collected from the interval in each boring that exhibited the highest PID readings or degree of staining and/or odors, and another sample was collected from the interval immediately beneath the observed impacts. In the absence of apparent contamination, one sample was collected from historic fill and one sample from immediately above the groundwater interface.

Soil boring locations are shown on Figure 2 and boring logs are provided in Appendix C. A total of 21 soil samples and one duplicate sample were collected into laboratory-supplied containers, including EnCore® samplers for volatile organic compounds (VOC) samples, chilled in laboratory-provided coolers to about 4 degrees Celsuis and transported via courier to Alpha Analytical in Westborough, Massachusetts (Alpha) under standard chain-of-custody protocol. Alpha is a New York State Department of Health (NYSDOH) Environmental Laboratory Accreditation Program (ELAP)-certified laboratory.

Each grab soil sample was analyzed for Target Criteria List (TCL) volatile organic compounds (VOCs) by United States Environmental Protection Agency (EPA) Method 8260, TCL semivolatile organic compounds (SVOCs) by EPA Method 8270, polychlorinated biphenyls (PCBs) by EPA Method 8082, and metals by EPA Methods 6010B/7471A.

3.3 Groundwater Investigation

Temporary groundwater monitoring wells (TMW01, TMW03, TMW08, TW09 and TW10) were installed in five of the ten soil borings under observation by Langan field engineers. The monitoring wells consisted of 10 feet of 0.01-inch slotted, Schedule 40 polyvinyl chloride (PVC) screen and attached PVC risers. The slotted PVC screen was located across the water table.

Temporary monitoring wells were purged and then sampled on the day they were drilled with a peristaltic pump using low-flow techniques to minimize drawdown. Groundwater quality parameters (pH, temperature, specific conductance, turbidity, oxidation-reduction potential [ORP], and dissolved oxygen [DO]) were measured and recorded at 5-minute intervals during purging using a Horiba multi-parameter water quality meter. Measurements were collected until the parameters stabilized to within 10 percent variability between successive measurements and the turbidity was below 5 nephelometric turbidity units (NTU) in all wells, with the exception of TW09, where turbidity did not stabilize after 75 minutes of purging.



Five groundwater samples plus one duplicate sample were collected into laboratory supplied glassware; placed in chilled, laboratory-provided coolers; and delivered via courier service to Alpha. The groundwater samples were analyzed for TCL VOCs by EPA Method 8260, TCL SVOCs by EPA Method 8270, PCBs by EPA method 8082, and total and dissolved TAL metals by EPA methods 6010B/7471A. Dissolved metals groundwater samples were collected using 0.45 micron (μM) field filters. The temporary groundwater monitoring well locations are shown on Figure 3. Groundwater sampling logs and well construction logs are provided in Appendix D.

3.4 Soil Vapor Investigation

Five sub-surface soil vapor probes were installed using Geoprobe® 6610DT and Geoprobe® 7722DT direct-push samplers. The probes were installed about two feet above the observed water table. The probes were installed in accordance with the NYSDOH 2006 Guidance for Evaluating Soil Vapor Intrusion in the State of New York and were comprised of a stainless steel screen threaded into polyethylene tubing. A sand filter pack was installed around the screen implant by pouring No. 2 sand into the annulus. The remainder of the annulus was filled to grade surface with a bentonite slurry seal.

Prior to sampling, a tracer gas test was performed using helium. The helium-tracer test is a quality assurance/quality control (QA/QC) measure to confirm the integrity of the implant seal by evaluating whether surface air has infiltrated the sample. The results of the completed helium-tracer gas tests confirmed the integrity of the sample seals.

Following the helium-tracer gas test, a PID was attached to the polyethylene tubing, and a total volume of at least three tubing and screen air volumes was purged. The purged soil vapor was also monitored for total organic vapors and the value was recorded in a soil vapor sampling log. After purging was complete, soil vapor samples were collected into laboratory-cleaned and batch-certified 2.7-liter, stainless steel Summa® canisters with regulators calibrated for 2-hour sampling intervals. The Summa® canisters arrived from the laboratory with over 30 inches of mercury vacuum (in Hg). Soil vapor sampling was terminated after about 2 hours or at about 6 in Hg, if this occurred before the 2-hour time period. An ambient air sample was also collected during the soil vapor sampling event. A laboratory-provided courier transported the samples to Alpha under standard chain-of-custody protocol for analysis of VOCs via EPA Method TO-15. The soil vapor sampling locations are shown on Figure 2. The soil vapor sampling log and soil vapor sampling point construction logs are provided in Appendix E.



4.0 OBSERVATIONS AND RESULTS

4.1 Geophysical Survey

The geophysical survey identified the following subsurface structures or anomalies:

Scattered anomalies were identified throughout the Site. Based on their reflection rate and appearance, the anomalies were inconsistent with characteristics of USTs.

An anomaly with characteristics consistent with a UST was identified inside the eastern boundary of the Site, adjacent to the automated-barrier gate providing access from Peck Slip.

Several utilities were located and boring locations were adjusted accordingly.

The Geophysical Survey Report is included as Appendix B.

4.2 Subsurface Observations

4.2.1 Soil Characteristics

Beneath the site-wide asphalt cap, historic fill material was observed within each soil boring to depths of about 6 feet bgs in SB4 to 14.5 feet bgs in SB8 and SB9. The historic fill typically comprised a loose grey brown fine to medium sand with varying proportions of silt, gravel, brick, concrete, wood and ash. The fill depth varied throughout the Site with no evident pattern. Native soil underlay the historic fill material and consisted of sands with varying proportions of gravel and silt. Bedrock was not encountered in any borings.

Visual, olfactory, and/or instrumental evidence of petroleum impacts were observed in SB3, SB8, SB9 and SB10. A 2-inch thick pink-colored horizon was observed in historic fill in SB9 at about 3 feet bgs, and a 6-inch blue-colored horizon was observed in historic fill in SB8B at about 7 feet bgs. Photographs of the colored soil horizons are included in with the soil boring logs in Appendix C.

Soil vapor results were evaluated using the NYSDOH 2006 Guidance Soil Vapor Decision Matrices and the corresponding ambient air sample results. Analytical results from the soil vapor samples are summarized in Table 3 and presented on Figure 5. Full laboratory reports are included in Appendix F.

Thirty-eight VOCs were detected in soil vapor samples. Total VOCs detected in soil vapor ranged from about 339 micrograms per cubic meter (μg/m3) in SV01 to about 5,353 μg/m3 in SV05. Total VOCs detected in the ambient air sample was 360 μg/m3.

The NYSDOH matrices address the compounds trichloroethene (TCE), tetrachloroethene (PCE), 1,1,1-trichloroethane (1,1,1-TCA), and carbon tetrachloride. The matrix evaluation presents a comparison of sub-slab and indoor air data for these VOCs and, based on the relationship between concentrations, provides recommendations for actions such as monitoring or mitigation. Indoor air samples were not collected as part of this investigation; however, the matrices provide a soil vapor concentration above which monitoring and/or mitigation is required, regardless of indoor air concentrations. As such, conservative comparisons of the soil vapor sample results were made with respect to the decision matrices.



Decision Matrix 1 of the NYSDOH Guidance addresses TCE and carbon tetrachloride. Carbon tetrachloride was not detected in any of the soil vapor samples. TCE was detected in three of the five samples at concentrations ranging from 1.09 μg/m3 (SV10) to 7.47 μg/m3 (SV03). TCE was not detected in ambient air. For TCE concentrations in soil vapor between 1 and 50 μg/m3, Matrix 1 recommends actions ranging from “no further action” to “mitigate”.

Decision Matrix 2 of the NYSDOH Guidance addresses PCE and 1,1,1-TCA. 1,1,1-TCA was detected in SV08 only, at a concentration of 1.49 μg/m3. PCE was detected in all soil vapor samples at concentrations ranging from 3.36 μg/m3 in SV01 to 82.7 μg/m3 in SV05. PCE and 1,1,1-TCA were not detected in the ambient air sample. For PCE concentrations of less than 100 μg/m3, Matrix 2 recommends actions ranging from “no further action” to “take reasonable and practical actions to identify sources(s) and reduce exposures”.

Several other VOCs were detected in soil vapor samples that were indicative of petroleum impacts; however, no Decision Matrices exist and there are no regulatory standards or guidance values established for other VOCs in New York State.



5.0 CONCLUSIONS

Based on the Site investigation, the following conclusions can be made:

Conclusions

Petroleum Spill – Based on field observations and analytical results from soil and groundwater samples TMW03, TMW08 and TMW09, a petroleum spill appears to have occurred in the east portion of the Site. A spill was reported using the NYSDEC spill hotline on October 13, 2015 and assigned Spill No. 1507371.

Potential USTs –The geophysical survey identified an anomaly consistent with a UST inside the eastern boundary of the Site, adjacent to the automated-barrier gate providing access from Peck Slip. This is the same area where a former auto repair garage was noted during the Phase I ESA. The location is also proximate to boring and monitoring well locations SB8, SB9, TMW08 and TMW09 where evidence of a petroleum release were apparent.

Soil –

o Soil Characteristics – Beneath the Site-wide asphalt cap, historic fill material was observed within each soil boring to depths of about 6 to 14.5 feet bgs. The historic fill typically comprised a loose grey brown fine to medium sand with varying proportions of silt, gravel brick, concrete, wood and ash. The fill depth varied throughout the Site with no evident pattern. Native soil underlay the historic fill material. Bedrock was not encountered in any borings.

o Petroleum-Impacted Soil – Visual, olfactory, and/or instrumental evidence of petroleum impacts was observed between 7 to 26 feet bgs in borings SB03, SB08, SB09 and SB10. In addition, analytical evidence of petroleum impacts were observed in samples collected from borings SB08 and SB09, where multiple VOCs and SVOCs were detected at concentrations above Unrestricted Use SCOs.

o Historic Fill –Multiple SVOCs and metals typically found in New York City historic fill were identified at concentrations above Unrestricted Use SCOs in soil samples collected from the historic fill layer across the Site. Atypical metal concentrations in historic fill, including arsenic, barium, copper lead, mercury, and zinc, were identified in several borings. Elevated metals may relate to the



previous historical commercial uses at the Site. A 2-inch thick pink soil horizon was observed in SB9, which coincided with concentrations of multiple VOCs and SVOCs above Unrestricted Use SCOs. A 6-inch blue soil horizon was observed in SB08B, which coincided with concentrations of multiple VOCs, SVOCs and PCBs above Unrestricted Use SCOs.

o Mercury Concentrations in Historic Fill– Mercury was identified at concentrations of 63 mg/kg and 120 mg/kg in SB4 and 6 mg/kg in SB9, which exceed not only the Unrestricted Use SCO of 0.18 mg/kg, but also the Restricted Use Commercial SCO of 5.7 mg/kg. Mercury concentrations in 3 of 21 samples were greater than 4 mg/kg, which is 20-times more than the Resource Conservation and Recovery Act (RCRA) hazardous waste limit of 0.2 mg/L; therefore, soil containing potentially hazardous concentrations of mercury is present at the Site. Previous historical use identified in the Phase I ESA included a mercury warehouse and thermometer company. Mercury detected in soil does not appear to be impacting groundwater.

Groundwater –

o Groundwater was encountered at depths ranging from about 7 feet bgs in TMW10 in the south to about 14 feet bgs in TMW08 in the north. Inferred groundwater flow is to the southeast towards the East River.

o Petroleum-Impacted Groundwater – Petroleum-related VOCs were identified in groundwater at concentrations exceeding TOGS Class GA SGVs in the east (TMW08 and TMW09) and northwestern (TW-14) portions of the Site. In addition, petroleum-related SVOCs were detected above TOGS Class GA SGVs in groundwater in TMW09. The turbidity was elevated during the sampling of TMW09; however laboratory filtering was not required. A petroleum-like odor and sheen were observed in purge water from TMW03 and TMW08.

o Metal-Impacted Groundwater – Total metals antimony, barium chromium, copper, iron, lead, magnesium, manganese, mercury nickel and sodium were detected in concentrations exceeding TOGS Class GA SGV. Dissolved antimony, iron, magnesium, manganese, and sodium were detected in filtered samples at concentrations exceeding TOGS Class GA SGVs. These metals are likely related to brackish groundwater conditions. Mercury, detected in soil does, not appear to be impacting groundwater.



Soil Vapor – Soil vapor sampling results indicate the presence of several VOCs, including chlorinated solvents and petroleum-related compounds, above the range of ambient air concentrations. The detected concentrations of PCE and TCE were applied to the NYSDOH matrices, the concentrations resulted in recommended actions ranging from “no further action” to “mitigate”.
