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 and Geology P.C. [E&E]) 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.


Date of Oversight Observation: December 12, 2018

Former ExxonMobil Terminal

Description of Activities

  1. Roux informed E&E that the first round of on-site DMR sampling was performed on 12/4, and the second round of DMR sampling will be performed on 12/18.
  2. Roux informed E&E that a new effluent pipe and vault is being installed adjacent to Newtown Creek to replace the existing outfall. The new effluent pipe will be 36-inch diameter as compared to the current 12-inch diameter pipe. The new vault, which was salvaged as part of the decommissioning of RW-J, is located between the RCS treatment system and Newtown Creek, and will house a check valve and weirs to ensure flow direction and velocity. Construction is expected to finish in January 2019.
  3. Roux informed E&E that the contractor has begun installing vaults at the wells that will be used in the water flooding program and the vault work is anticipated to finish by the end of the year. Piping and instrumentation installation is anticipated to begin in early 2019.
  4. E&E observed the on-site treatment system in operation and recorded current operating parameters of the air strippers from the control screen.
  5. E&E and Roux collected a sample of the on-site effluent for visual obsevation and compared it to a previously collected sample taken from Newtown Creek in the vicinity of the outfall.

 Planned Activities

  1. Routine treatment system maintenance.
  2. Continuation of new effluent piping construction.
  3. Continuation of vault installation for the water flooding program.

ExxonMobil Off-Site Plume Area

Description of Activities

  1. Roux informed E&E that the first round of off-site DMR sampling was performed on 12/6, and the second round of DMR sampling will be performed on 12/20.
