Site Description[1]

The approximately 1 acre site is described on the county tax map as Block No. 2487, Lots No. 1, 10, 12, 72 and 78. The dimensions of the site are approximately 240 feet by 200 feet. The building consists of a number of smaller buildings that have been joined together. A line of row houses is situated across the street to the south. Commercial buildings are situated directly across the street to the north. To the west is a park and to the northwest is a paved lot which is used for truck storage.

The site has been in existence since 1887. It has been used for manufacturing, as an office, for storage, and for shipping and receiving. Prior to the late 1940s, the site and the surrounding lots were used as a boiler shop for Logan Ironworks, two stables, a gas and light fixture factory, a sheet metal works, a soap factory, a waterproofing factory, and a scrap metal facility. The subject property was developed for plastic manufacturing sometime in the late 1940s to early 1950s and remains relatively unchanged since that time.

The plastics factory was bought by Nuhart and Company’s Sol Graf in 1983.[2]  For 21 years, Nuhart made vinyl siding, sheet metal, foam rubber and asbestos sheeting.  Graf hired many new Soviet Jewish immigrants to make up his workforce and his hiring and employment practices were reportedly admirable, providing well-paying jobs to a new immigrant community.  However, Greenpoint environmental advocates criticized working conditions inside the plant and the smells and noxious emissions that that came from it.

After 2004, NuHart removed all of their equipment and offices. The site is now used for the storage of plastic wrapping and many large (36 cu. ft.) fabric bags containing pellets of resin. There are 12 underground storage tanks located on the Site. According to records, these tanks were emptied and closed as part of an Interim Remedial Measure (IRM). There are also two large aboveground silos on site. The Petroleum Bulk Storage (PBS) number is 2-608875, and the Chemical Bulk Storage (CBS) number is 2-000444. Liquid plasticizers stored included bis(2-ethylhexyl)phthalate, bis(2-ethylhexyl)adipate, and palatinol 711P phthalate.

Site Environmental Assessment
The plasticizers bis(2-ethylhexyl)phthalate, Di-n-Octyl phthalate, as well as high boiling, paraffinic, petroleum oil have been found in the groundwater (both as non-aqueous phase liquid and in the dissolved phase) and in soil. After manufacturing ceased in 2004, environmental investigations were performed. The investigations identified soil and groundwater contamination consisting of liquid plasticizers and petroleum. The amount of material released is unknown. Soil concentrations as high as 20,000 ppm of bis(2-ethylhexyl)phthalate were detected in soil boring SB-44. Non-aqueous phase liquid (NAPL) was found at thicknesses of up to 5 feet in one well. According to the Interim Investigation Report dated April 2010, a large plume of plasticizer NAPL mixture consisting of phthalates and paraffinic petroleum was identified under the western end of the factory where the plasticizer underground storage tanks were located. A small plume of NAPL consisting primarily of phthalate was identified beneath Lot 12 near one of the plasticizer tanks. The large plume has migrated off-site in a northwesterly direction under the sidewalk.

Previous interim remedial measures (IRMs) implemented under the spill program involved cleaning the floors of the factory, cleaning out the USTs, cleaning all sumps and pipe gallery wells, installing monitoring wells, and installing NAPL collection wells and recovery equipment. NAPL recovery has been ongoing since 2007. As of December 2008, the total NAPL recovered was 8,356 gallon. The most recent gauging data (April 2010) indicates the thickness of the NAPL ranges from 0.15 feet to 4.87 feet.

Site Health Assessment
It is unlikely that people will drink contaminated groundwater since the area is provided with public water. It is also unlikely that area residents will come in contact with contaminated soil since it is underground, however, if the site is redeveloped, construction workers or future site occupants may come in contact with site related contamination in soil if it is not handled properly. Also, the potential for nearby residents and building occupants to breathe site-related contaminants that may migrate into nearby structures via soil vapor intrusion needs to be evaluated.
