The site is comprised of numerous properties between 16th St, 20th St, Tenth Avenue, and the Hudson River in Manhattan. One additional parcel is located on 18th Street, east of Tenth Avenue. The site is the location of the former 18th Street Gas Works, which operated between 1833 and circa 1900. The gas holders remained in operation until 1914. A Site Characterization Work Plan was approved in February 2004. The SC Report was submitted in January 2006 and was approved in April 2006. A RI work plan was included with the SC report and was also approved in April 2006. Field work for the RI is ongoing and is expected to be completed in 2008, with a site-wide RI expected in 2009. Several properties are under development within the site: 1) Georgetown Development: The West 19th street Site (C231017) has been remediated (partial excavation and containment) and has received its final Certificate of Completion in 2006. 2) West Chelsea Development: A property at 535 W 19th is being remediated as Operable Unit 2 to facilitate development. Remedial Action (partial excavation and containment) is completed, and a final engineering report is expected in 2008. 3) Gasser Property: Remediation of the property at 524 W. 19th Street is being tracked as Operable Unit 3. Remediation (partial excavation and containment) is underway and should be completed in 2008. 4) Edison Property (Highline Towers): The propety located between 17th and 18th Street, and 10th and 11th Avenues (currently an at-grade parking lot) is also to be developed. The investigation was completed in 2007 the Alternatives Analysis was approved in May 2008, which selected in-situ solidification, containment, and IC/ECs as the remedy. The remedial action work plan and remedial design are expected to be completed in 2008.Site Environmental Assessment
A Site Characterization Report was received in January 2006. SC results along with previous investigations from this site along with results from the West 19th Development Site (V00624 and C231017) indicate extensive MGP contamination is present, including NAPL on many parcels.
Site Health Assessment
Public water is provided to the area, thereby preventing exposures to groundwater. The area is covered with buildings or pavement, thereby preventing direct contact with contamination. The investigation of the whole site is on-going and data will be evaluated as they become available.
