The site is located on a triangularly shaped parcel in the upper west side of Manhattan, at the corner of Broadway and Nagle Avenue. The area of the site is approximately 0.36 acres. The site is paved and fenced, with a small one story building at the northeast corner. The site is currently a 24 hour parking facility, but until 2005 was used as a gasoline service station. The surrounding parcels are currently used for a combination of commerical and residential. Adjacent to the site on the north side is an eight story residential apartment building. Fort Tryon Park is located west of the site across Broadway. Prior use that appears to have led to site contamination includes leaks and spills from gasoline service station operations. A Brownfield Cleanup Agreement was executed in September 2006. The Citizen Participation (CP) Plan was approved in December 2006, and the Remedial Investigation workplan was approved in October 2007. A Remediation investigation is underway.
Site Environmental Assessment
The primary contaminants of concern at the site include benzene, tolulene, ethylbenzene, xylene (BTEX), methyl tertiary butyl ether (MTBE) and other petroleum related compounds. Data from previous investigations indicate soil and groundwater have been impacted by petroleum hydrocarbons. Exceedances of standards, criteria, and guidance include BTEX and MTBE in soil and groundwater. Depth to groundwater ranges from 7.5 to 12 feet. Currently there is insufficient data to make a determination regarding significant threat.
Site Health Assessment
Information submitted with the BCP application regarding the conditions at the site are currently under review and will be revised as additional information becomes available.
