Public Comment Period Runs Until April 15, 2024

The Gowanus Canal Natural Resource Damage Assessment Trustee Council, comprised of the National Oceanic and Atmospheric Administration (NOAA), New York State Department of Environmental Conservation (NYSDEC), and the United States Department of the Interior’s U.S. Fish and Wildlife Service (USFWS), have released the draft Natural Resource Damage Assessment Plan (NRDA) for the Gowanus Canal, which “describes the Trustees’ proposed approach to conducting the NRDA, summarizes existing data, and outlines potential analyses and studies that may be used to evaluate contaminants and their effects on Gowanus Canal natural resources and resource services.”

The plan will guide the Trustees in seeking monetary damages from the potentially responsible parties (PRPs, the entities held liable for the contamination of the canal) for the restoration of natural resources and resource services resulting from the contamination of the canal, and compensating the public for interim losses until restoration. The plan describes the Trustees’ “proposed approach to conducting the
NRDA, summarizes existing data, and outlines potential analyses and studies that may be used to evaluate contaminants and their effects on Gowanus Canal.”

You can download a copy of the draft Natural Resource Damage Assessment Plan here, and a copy of the pre-assessment screen, prepared in December 2014, here. A hard copy of the plan is also available for review at the Park Slope branch of the Brooklyn Public Library, at 431 6th Avenue.

You can submit your comments on the plan through April 15, 2024, to:

USEPA Region 2 provided us with the following update on the status of the Gowanus Canal Superfund cleanup on February 27 (edited slightly for elucidation).

In-Canal Work

Remedial Target Area (RTA) 1 (Top of the canal to 3rd Street)

  • The Potentially Responsible Parties (PRPs) are currently laying down the armor mat layer in the canal. They started this stage of the remediation in early November 2023. Mats are inspected for cracks or defects prior to placement and divers measure the spacing between mats. They have currently laid down approximately 132,455 square feet of mats to date (approximately 75% of the total).
  • We expect mat placement to continue until March 2024, followed by subsequent material. Demobilization will occur sometime in May 2024.
  • After mat placement, grout is used to fill in the spaces between the mats. We have held off on placing grout in the top 275 feet of the canal due to a NAPL (non-aqueous phase liquid, a contaminant) issue and within 50 feet of the Carroll Street bridge until the repairs have been completed.
  • Once grout is placed at the head of the canal, the flushing tunnel will be turned back on.
  • The Trust (Gowanus Canal Environmental Remediation Trust established by the PRPs to perform cleanup work) has been conducting air and noise monitoring throughout. They have also been conducting movement and vibration monitoring.
  • We haven’t had any major issues with dissolved oxygen (DO) since the weather cooled off. Still monitoring as significant weather events can also influence the DO.
  • NAPL sheens and blebs have been spotted near the head of the canal
    • From what we see so far visually, it appears that the NAPL seems to be on the surface and that the cap is intact.
    • We don’t yet have results back from the analytical samples that were taken in the vicinity to determine the source of the NAPL.

RTA2 (3rd Street to 9th Street)

  • We are working on the design for the next section of the canal (RTA2) and the 3rd Street Bridge, 4th Street Turning Basin, and 5th Street Turning Basin (3/4/5 Area). RTA2 will be similar in design to RTA1 as it includes dredging, in-situ stabilization, and capping. 
  • We’re currently working with the Trust on the bulkhead designs for RTA2 and coordinating the remediation for all the various parcels and properties.
  • We do not have any updates on the status of the design for the Carroll Street Bridge repair. Design still being worked on.

Combined Sewer Overflow (CSO) Tanks

  • Installation of the perimeter slurry wall at the Red Hook CSO retention tank site on Nevins Street is ongoing. The work is approximately 40% complete and on schedule to be finished by late June/July 2024. In response to odor complaints, the City is constructing a tent over equipment that removes soil and debris from the slurry used in the perimeter wall and can create odors. The tent structure and fabric are in place, though some additional work is needed on the HVAC system in order for the tent to be fully functional. 
  • Asbestos abatement along with debris removal and disposal has begun at structures slated for demolition at the Owl’s Head tank site. Building demolitions are scheduled to begin later this spring.

Upland Sites

  • No new updates

On January 23, 2024, Pat Evangelista, Director of EPA Region 2’s Superfund and Emergency Management Division, sent the letter posted below in response to a resolution passed by the Gowanus Canal Community Advisory Group at its October 24, 2023 general meeting, which asked the EPA to assume responsibility for remediating the entirety of the former Citizens Manufactured Gas Plant site under the auspices of the Gowanus Superfund cleanup, due to the ongoing inability of National Grid and the New York State Department of Environmental Conservation to gain access to the site’s Parcel 4.

The Admin committee met briefly via zoom on February 1st to review Erica Eliason’s CAG application.

It was agreed that her application should be forwarded to the full CAG for an interview and vote.

Joan Salome-Rodriguez, Rita Miller and Katia Kelly attended the meeting and quorum was achieved.

(Louis Kleinman joined briefly at the beginning of the zoom to let us know that he was in favor of moving the application forward.) 

Assembly Member Jo Anne Simon, in partnership with the offices of Representative Dan Goldman, Senator Andrew Gounardes, and Council Member Shahana Hanif, will host a community forum with the New York State Department of Environmental Conservation (DEC), New York State Department of Health (DOH), and the Environmental Protection Agency (EPA) on the ongoing Brownfields Project. They will specifically be discussing the Soil Vapor Testing that is taking place. This forum is a space for those new to the Gowanus cleanup to come and ask their questions and learn more about the project. The community forum will be held on January 25 from 6 p.m. to 8 p.m. at Wyckoff Gardens Community Center, 280 Wyckoff St, Brooklyn 11217.

Contractors working under the supervision of the U.S. Environmental Protection Agency (EPA) are in the process of installing the final components of the protective cap that will protect the Gowanus Canal from recontamination and restore the canal bed as an attractive habitat for marine life.

At its October 24, 2023 general meeting, the Gowanus Canal Community Advisory Group passed the following resolution, initiated by the Land Use Committee, asking U.S. EPA Region 2 to assume responsibility for remediating the entirety of the former Citizens Manufactured Gas Plant site under the auspices of the Gowanus Superfund cleanup, due to the ongoing inability of National Grid and the New York State Department of Environmental Conservation to gain access to the site’s Parcel 4.

The resolution reads as follows:

Background:

It has come to the Gowanus Canal Community Advisory Group’s (CAG) attention that National Grid and NYSDEC (DEC) have not been able to gain access to Parcel 4 (Bklyn Block 468, Lot 25) of the former Citizens MGP Works site for several years because the property owner refuses to allow access to the property. This prevents National Grid and DEC from performing sampling of the existing monitoring wells and implementing DEC’s approved Supplemental Soil Investigation Work Plan as part of NYSDEC’s Superfund Program. The CAG understands that Parcel 4 remains heavily polluted with cancer-causing substances harmful to the community.

It is thus resolved that:

– due to DEC and National Grid’s inability to gain access to Parcel 4 to perform crucial environmental work on the site, and;

– given the fact that the site remains polluted and that Parcels 1, 2 and 3 have not been remediated to “pre-disposal” conditions according to New York State Law and;

– according to a 2005 report on Public Place by GEI that documents that coal tar and other toxins have already moved off Parcel 4 and have been detected along 4th Street, on Hoyt Street and are flowing towards the Gowanus Canal and;

– due to the four sites’ extremely high ground water levels, recent flooding in the area and subsurface intrusion that may have occurred in neighboring buildings where volatile organic compounds (VOCs) may have entered as vapors or as groundwater and may be volatilizing in the buildings,

CAG thus points out not only the real risk of recontamination between Parcel 4 and the other three former Citizens MGP Works site parcels, butmore importantly, the likelihood of recontamination of the EPA’s Gowanus Canal Superfund site.
