East 20th - East 22nd Sts., New York, NY, 10010

Stuyvesant Town

VCP MGP VOCs "Vapor Intrusion" brownfield

Site Description[1] 
The site is the location of a former manufactured gas plant, which operated between circa 1848 and 1945. The site is bounded by Avenue C, First Avenue, 20th Street, and the former 22nd Street. Portions of the historic site boundary extend east of Avenue C. Currently, the entire footprint of the former MGP (and some surrounding area as well) is occupied by the Peter Cooper Village apartment complex. During 2003, coal tar was found seeping into a new steam tunnel along First Avenue at approximately 22nd Street at a depth of 80-85 feet below ground surface. Significant MGP impacts were found in the subsurface across the entire site during the SC, and the site was moved into the RI phase directly. The RI report was submitted in early 2007. It was determined that additional investigation was needed. Separate operable units for the East River (OU2) and the bedrock beneath the site (OU3) have been created. SRI work plans for additional work, at OU1, OU2, and OU3, was received in December 2007 and is under review.

Site Environmental Assessment
During 2003, coal tar was found seeping into a new steam tunnel along First Avenue at approximately 22nd Street at a depth of 80-85 feet below ground surface. A Site Characterization was completed in early 2004 and the SC Report is currently under review. Preliminary results of the SC indicate significant MGP impacts in the subsurface across the site, including several NAPL source areas. A Remedial Investigation has been proposed by Con edsion to further define the extents of contamination at the site.

Site Health Assessment
Public water is provided to the area, thereby preventing exposures to groundwater. Site-related contamination has been found, but it is not available for direct contact. Current data indicate that vapors are not migrating into on-site residential buildings. Additional data will be assessed as it becomes available.
