NYSDEC Oversight

The NYSDEC provides oversight of activities conducted by the major responsible parties at various Greenpoint petroleum remediation sites in Brooklyn, New York. NYSDEC’s subcontractor (Ecology and Environment Engineering P.C.) conducts bi-weekly field oversight of PRP activities to assist NYSDEC in developing a better understanding of the day to day investigation and remedial activities that occur in the Greenpoint area and report any pertinent issues to NYSDEC’s project manager.

The following sections summarize recent activities observed at the various Greenpoint remediation sites in Brooklyn, New York.
