Brownfield CVOCs PCBs VOCs "Vapor Intrusion" SSDS

C.E. Flushing, LLC
Site Description[1] 
Flushing Industrial Park is a 13.6 acre property. The property has been divided into 4 parcels for development purposes.  In August 1998, the Downtown Flushing Rezoning Resolution redesignated the site from M3 (Heavy Manufacturing), to C4-2 (Commercial). The site was a former Con Edison property for more than 30 years. Con Edison used the site mainly for storage and maintenance of electric transformers containing PCBs oil. On site buildings were used as a garage, a blacksmith shop, an incinerator, a paint house, a gas station, offices, a cloth manufacturing work shop, a car repair shop, a storage warehouse, a distribution facility for electronics, and large parking areas including a junkyard. The industrial uses of the site and uncontrolled dumping through dry drains represent the source of the contamination in soil and in groundwater at the site. The neighborhood is mixed manufacturing, commercial, and residential. In September 2005 an IRM work plan was approved, and in December 2005 the IRM remedial field activity started. In June 2006 the Remedial Action Work Plan was approved. The contemplated use of Parcel 2 is commercial with high-rise residential apartment buildings. The Final Engineering Report was approved and a Certificate of Completion was issued on December 27, 2007. Site management is ongoing.

Site Environmental Assessment
Phase I and Phase II of the Environmental Investigation of Flushing Industrial Park revealed soil contaminated by PCBs (aroclor 1260) ranging in from 0 to 4,480ppm; metals including arsenic (ranging from ND to 23.3ppm), cadmium (ranging from ND to 4.88ppm), lead (ranging from ND to 9,200ppm), mercury (ranging from ND to 5.58ppm), nickel (ranging from ND to 66.7ppm); volatile organic compounds (VOCs),including acetone, benzene, ethylbenzene, chlorobenzene, 1,1,2,2-tetrachloroethane, toluene, xylene; semi volatile organic compounds (SVOCs) including policyclic, aromatic hydrocarbons, including anthracene, benzo(a)pyrene, benzo(b)fluoranthene, benzo(k)fluoranthene, fluorene, fluoranthene, naphtalene, phenanthrene; pesticides including aldrin, endrin, endosulfan, toxaphene.  Concentrations of these contaminants in soil and groundwater exceeded the NYSDEC recommended soil cleanup objectives and Class GA groundwater standards, respectively. The site presented a significant threat to human health and the environment due to releases from the source areas of contaminants into the groundwater. Remediation of Parcel 2 was required prior to development and re-use of the site as a commercial/residential building. In July 2006 the RAWP was approved and the remedial field work started in accordance with this RAWP, HASP, SGMP, and SWPPP. After the demolition of the main building, the slab was removed and the contaminated soil (above site specific action levels, or SSALs) under the slab was excavated. Extensive excavation of the contaminated soil, including soil below the water table to the extent practicable, was performed. On the westernmost retail building foot print a sub-slab soil gas/vapor depressurization system and a soil gas barrier were installed. An environmental easement was recorded to ensure proper implementation of the Site Management Plan (SMP). The Site Management began with approval of the Final Engineering Report and issuance of the CoC on 12/27/2007. The Department does not foresee any unacceptable impacts to the environment from the site provided the SMP continues to be implemented.

Site Health Assessment
Soil and groundwater are contaminated with volatile and semi-volatile organic compounds, metals, and PCBs. Exposure through ingestion of contaminated groundwater is unlikely since the area is served by public water. Currently, site access is restricted and contaminated soil is being excavated and removed as an interim remedial measure. The remedy will include a site-specific cap to minimize the potential for exposure to residual contaminated soil. The lower level of the proposed building is a ventilated garage, which will minimize the potential for exposures due to soil vapor intrusion.
