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: June 11, 2019

Former ExxonMobil Terminal

Description of Activities

  1. E & E observed the on-site treatment system in operation and recorded current operating parameters of the air strippers from the control screen.
  2. Roux informed E & E that the first round of on-site monthly DMR sampling was performed on 6/11, and the second round of DMR sampling will be performed later this month.
  3. Roux informed E & E that the three wells serving the new waterflooding program are in operation. Injection of treatment system effluent water is occurring at a rate of 20 gallons per minute (gpm) at each well. The rate of product recovery and other performance parameters downstream of recovery wells are being monitored to determine the effectiveness of the waterflooding program.
  4. Roux informed E & E that they are in the process of installing an elevated catwalk around the on-site treatment system carbon vessels for accessibility.
  5. Roux informed E&E that the backfilling and installation of a steel grate at the top of the new effluent vault has been completed.
  6. Roux informed E&E that a contractor has been selected to perform the removal of PCB-contaminated soil at the creek-side area of 460 Kingsland Avenue. The contractor is expected to mobilize and begin excavation work by the end of June. This work is projected to take 3-4 months to complete.
  7. E & E and Roux collected a sample of the on-site effluent for visual observation and compared it to a previously collected sample taken from the Newtown Creek in the vicinity of the outfall.

 Planned Activities

  1. Routine treatment system maintenance.
  2. Continuated operation of the water flooding program.

ExxonMobil Off-Site Plume Area

Description of Activities

  1. Roux informed E & E that the first round of off-site monthly DMR sampling was performed on 6/7, and the second round of DMR sampling was performed on 6/10.
  2. Roux informed E & E that the off-site treatment system was shut down after the second round of DMR sampling on 6/10 to repair sand filter vessel DS-1 and replace the sand media. It is expected DS-1 will be repaired and back in operation by 6/21.
  3. Roux informed E & E that the process tank for the off-site treatment system is being inspected for leaks while the system is offline.
  4. E & E and Roux collected a sample of the off-site effluent for visual observation 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 DS-1 sand filter vessel maintenance work.

KM Terminal (Former BP Terminal)

Description of Activities

  1. Antea informed E & E that MW-6 vault was repaired on 6/10 after it was identified that rainwater was infiltrating the vault due to asphalt that settled and clogged the vault’s drain port.
  2. Antea informed E & E that an access hatch was installed on a vertical face of the treatment system’s equalization vessel and that the equalization vessel was cleaned.
  3. E & E and Antea collected a sample of the on-site effluent for visual observation and compared it to a previously collected sample taken from the Newtown Creek in the vicinity of the outfall.

 Planned Activities

  1. Routine treatment system maintenance.

Former Paragon Oil Terminal/Apollo Street Creek Parcels

Description of Activities

  1. Arcadis informed E & E that routine O&M activities are being conducted today that includes monitoring sensors from control panels, well product gauging, and troubleshooting a software/programming issue.
  2. Arcadis informed E & E that Empire Merchants will have a two-week shutdown starting 7/22. During this time, Arcadis will perform groundwater sampling, PID screening, sealing of cracks and seams, and manual product bailing from wells within the warehouse.
  3. Arcadis informed E & E that bulkhead inspections are being performed at 4-6 weeks by boat from the creek side of the bulkhead.

 Planned Activities

  1. Routine treatment system maintenance

Newtown Creek Observations

Former Paragon Terminal Bulkhead
E&E observed conditions along the upper, middle, and lower bulkheads, within the containment areas, and in Newtown Creek in the vicinity of the bulkhead. No sheens or sediment plumes were observed.

Meeker Avenue Bulkhead
E&E observed the conditions of Newtown Creek at the end of Meeker Avenue in the vicinity of the ExxonMobil Off-site outfall and adjacent storm outfalls. Storm outfall D was observed as partially submerged in the creek. No sheens or sediment plumes were observed in the vicinity or within visible distance upstream or downstream of the outfalls. This observation took place approximately 2 hours and 40 minutes after the 5:56 AM 4.2’ AMSL high tide.
