SCARSDALE, N.Y. – Cleanup has been completed and a final engineering report is under review regarding the contaminated Heathcote Corners site on Palmer Avenue in Scarsdale as part of the state’s Brownfield Cleanup Program.
Heathcote Corners II, LLC. undertook the cleanup, in coordination with the New York State Department of Environmental Conservation (NYSDEC). Heathcote Corners II submitted a final engineering report for review that deems the site as safe, and is waiting on approval from the NYSDEC.
If the organization approves the final engineering report, it will issue a certificate of completion, which would allow the site to be redeveloped, according to a report from the NYSDEC. It is currently zoned for commercial use, with the surrounding parcels of land zoned for both commercial and residential uses.
The certificate would exempt Heathcote Corners II from liability to the state for contamination at or coming to the site, and it would be eligible for tax credits to offset costs of performing cleanup activities and redevelopment of the site.
The NYSDEC’s report says the site contained an inactive service station, two fuel pump islands and a paved parking lot. Prior uses at the site have led to contamination that includes leaking underground fuel and waste oil tanks. In 2008, Environmental Site Assessments (ESAs) identified the presence of petroleum-related contamination at the site.
All on-site underground storage tanks were removed and disposed of, the report says. During the construction of the new parking garage in the area, a vapor barrier was installed to prevent vapors, which may emanate from contaminated groundwater from entering the parking garage.
An oxygen release compound was applied to the base of the excavation site to treat residual groundwater contamination and a monitoring plan was put in place to assess the performance of the remedies through the sampling and analyzing of groundwater.
When the final engineering report is approved, it will be available to the public at the Scarsdale Public Library and NYSDEC in New Paltz.
