Atlas Park, LLC
Site Description[1] 
In 2003, the 20 acre Atlas Terminals (bound by 80th and 83rd Streets to the west and east, respectively, and Cooper Avenue and the LIRR right of way to the north and south, respectively) was decomissioned for Railroad use.  In 2004, most of the buildings were torn down and in 2006 the Shops at Atlas Park, a retail mall, opened on the 12-acre western portion of the site.[2]

The original Brownfield Ccleanup Agreement covered a 12-acre site. However, Atlas Park was subsequently separated into two distinct areas: Parcel A (formerly known as the IRM Area and, retained the original BCA site No. 241045) and Parcel B (formerly known as the RI Area now designated BCA No. 241088). With concurrence of NYSDEC, the owner of the site proceeded with administrative process to separate Parcels A and B into separate Brownfield Cleanup Agreements. The original BCA has been amended to reflect the IRM Area as Parcel A, and the RI area as Parcel B. Amendment agreements were executed on October 11, 2005. Parcel A (the Site) consists of an 8.474-acre portion of the 12-acre Atlas Park site. Atlas Park now includes nearly 400,000 square feet of shopping, entertainment, dining, and office space. Atlas Terminals, an 80-year-old industrial park, is situated at the intersection of Cooper Avenue and 80th Street, in the Glendale Section of Queens. The former 44-building, one million square-foot park once served as an urban industrial park. The site was a center for the rag and knitting trades. As the industrial base of Queens declined, the site uses shifted to a mix of distribution/warehousing and knitting. The areas surrounding the Site are zoned mixed and manufacturing. The Site is located directly south of St. John’s Cemetery. The areas west of the Site is Atlas Park - Parcel B, which consists of former industrial use buildings undergoing renovation. Further west, the properties across 80th Street are predominantly zoned for light manufacturing, with some private residences. There is an industrial, triangular-shaped property to the south between the Site and Long Island Railroad easement; the areas immediately south of the LIRR easement are primarily residential. The remaining Atlas Terminals industrial site lies due east of Atlas Park; the area further to the east across 83rd Street is a mixture of residential and manufacturing properties. In 1867 the site consisted primarily of farmland. Several buildings occupied the Site prior to 1922, although their historical use is unknown. In 1922, the approximately 20-acre property was sold to the Hemmerdinger Corporation and the Site became known as Atlas Terminals. The Hemmerdinger Corporation leased portions of the Site to various manufacturing and processing companies from 1922 to the present. A Certification of Completion was issued on December 31, 2005.

The principal environmental history of Parcel B is related to the textile industry. There were industrial tenants present over the years, which were suspected to have contributed contamination to the Site. The surrounding parcels are currently used for a combination of commercial, light industrial and residential uses. The Supplemental Remedial Investigation indicated that site contamination Areas of Concern include: elevated levels of SVOCs and metals above NYS RSCOS, two 20,000 gallon No. 6 fuel oil USTs, sub floor vaults and drain lines, transformers and an area with lead contamination. In addition, TCE and PCE soil vapors previously measured at Parcel A have been attributed to a source area on Parcel B. Significant amounts of PCE and TCE have been measured in groundwater and soil vapor under the site and the surrounding neighborhood. Historic use in Buildings 3 and 8 indicates usage and improper disposal of PCE and/or TCE. Such substances were apparently poured down drains resulting in soil hot spots, groundwater and soil vapor contamination.

Site Environmental Assessment
The contaminants of concern within Parcel A included (prior to remediation) some metals and semi-volatile organic compounds, and very limited volatile organic compounds (VOCs) in the groundwater and soil vapor beneath the Site. No on-site source of VOCs was identified in the historic fill or soil at the Parcel A. Given the detected concentrations of individual VOCs were below TAGM 4046 recommended soil cleanup objectives, VOCs were not contaminants of concern for the remedial activities which were completed on Parcel A in December 2005. The contaminants of concern (COCs) are discussed below: Soil - The COCs for the historic fill layer were identified to be seven PAHs, namely benzo(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(a)pyrene, ideno(1,2,3-cd)pyrene, and dibenzo(a,h)anthracene, and metals, which consisted of mercury, arsenic, cadmium, chromium, copper, and lead. During implementation of the remedial excavation, previously unknown pockets of hazardous waste contamination have been discovered, which were associated with discovery of underground storage tanks, drums,vaults, etc. These pockets of hazardous waste contamination have been excavated and end-point confirmatory sampling verified that the remedial objectives have been met. Groundwater - PCE and TCE were detected in the groundwater aquifer more than 55 feet beneath the Site at concentrations above their respective Ambient Water Quality Standards. However, they were not considered COCs for groundwater because direct contact with groundwater is unlikely. PCE and TCE in groundwater were considered with respect to their potential to volatilize from the groundwater beneath the Site and migrate upwards in a vapor phase (see below). Soil Vapor - PCE was detected in the one soil vapor sample collected on the Site at a concentration above the NYSDOH guidance value. However, PCE is not considered a COC for soil vapor because there were no on-Site sources identified on Parcel A. The occurrence of PCE (and TCE) was considered and evaluated given their presence in groundwater beneath the Site and potential to migrate upwards from groundwater towards the planned new Site buildings, and given the recent NYSDOH guidance values limiting their concentrations in indoor air and soil vapors. Soil gas and the potential for soil vapor intrusion within proposed buildings was investigated across the site. As a precautinary measure to prevent potential human exposures from soil vapor intrusion, several sub slab depressurization systems were installed beneath the new buildings. These systems will be continually operated and annually certified as part of the separate but adjacent Parcel B final remedial measure. The remediation of the Parcel A site was completed in late 2005 and Certificate of Completion was issued in December 2005. The concentrations of constituents of concern underlying the existing and future buildings in the IRM area (Parcel A) were allowed to remain in place provided the building's concrete floors remain intact and a sub-floor depressurization system is installed to vent soil gasses to the outside air. Based on low concentrations of Contaminants of Concern (COCs) in groundwater, no identified on-Site source on Parcel A, and absence of potential exposure pathway, i.e not used a local drinking water source, no further investigation nor remediation of groundwater is warranted on Parcel A. The regional groundwater conditions and the concentrations of contaminants found beneath the Parcel A site, did not warrant groundwater to be considered a media of concern and did not require any deed restrictions or engineering controls. Soil gas and the potential for soil vapor intrusion within proposed buildings was investigated across the site. As a precautionary measure to prevent potential human exposures from soil vapor intrusiton, several sub-slab depressurization systems were installed beneath the new buildings. Presumed future use of the site will remain a commercial and retail complex, these systems will be continually operated and annually certified as part of separate but adjacent Parcel B final remedial measure.

Site Health Assessment
The site remediation has been completed to Track 1 cleanup levels and is now open to the public. No source for soil vapor contamination was found on the Atlas Park Parcel-A site and the mitigation measures installed in the new on-site buildings are managed under the Parcel-B site management plan. The site is served by public water and no exposure to on-site groundwater is expected.

The site cleanup has been completed to Track 4 restricted commercial use criteria an is now open for public access. On-site groundwater and soil vapor contamination will be remediated by two Soil Vapor Extraction/Air Sparging systems operating full time. All buildings open for public access have had active sub-slab depressurization systems installed in them. The public is not expected to come in contact with any contamination remaining on-site since it is capped and managed with a site management plan. Public water supplies serve area residents from the New York City public water system.
