4) At our previous Committee meeting we discussed the former Citizens MGP Works site’s recent Groundwater Monitoring report and asked National Grid’s representative, Irene Baker, if there was a similar report for the former Fulton MGP site. Ms. Baker did respond stating: “There was other recent groundwater monitoring completed at Fulton, which is included in a Sentinel Well Monitoring Summary Report (2025). I recommend contacting DEC directly for that information”.
Action: The Committee asked Steve to reach out to the DEC to request this report. Update: Aaron Fischer did respond to the entire committee on December 23rd. Please review and be prepared to discuss at our January meeting.

Minutes of the December 1, 2025 Meeting of the Gowanus Canal CAG’s Water Quality & Technical Committee

Attendees: Joan Salome-Rodriguez (Moderator), Corinne Brenner, Erica Eliason, Katia Kelly, Louis Kleinman, Emily Mitchell, Jason Schwartzman, Susan Yung

Housekeeping:

1. Victoria is looking for any map/image that shows where the legal sewage outfalls are located. Joan followed up. Will follow up again.  

2. Suggested we FOIL NYC Topographical about the status of the streets abutting Power House. De-mapped and made private?  

3. Committee reviewed Emily Mitchell’s draft re: hydrogeological study for the Gowanus re-zone area (Clinton St to 4th Avenue east-west and Dean Street to 19th Street north-south) and made edits.  Emily will complete and share with Joan who will distribute to attendees for finalizing. This will get added in the letter: Can DEC test groundwater pooling in basements or on properties for contaminants? Request goes to DEC.

4. Natalie said that DEC was doing a full hydrology study that should have been completed in 2024. I have asked Aaron Fischer for it twice and so has Steve from Land Use. No response yet.

5. Did not cover but Joan followed up with Victoria as to whether climate change can be taken into account in future mounding/hydrology studies performed by the Trust. Likewise, no response. Joan will follow up again.  

6. Katia followed up with Natalie Loney at EPA to find out when the Operation and Maintenance Plan (OMP) for the Gowanus Canal will be complete. Apparently the PRPs will be responsible for carrying out the OMP regarding the cap and the water quality. Katia to follow again with Natalie.

NEW ISSUES

1. DEFERRED: State issued its water quality determinations for various water bodies, including the Canal. Result – Gowanus Canal is now a Class SC waterbody which is what we initially asked for (though we followed by asking for Class SB). Cup half full, I guess. There is some indication that SC will allow swimmable water quality standards to be legally enforceable in the canal. Riverkeeper will give an update. Deeper discussion with Em Ruby and Mike Dulong, who said they can attend the December 1 meeting.  https://link.edgepilot.com/s/f6a68fad/8LGwi7kO_UGxhg38H5AVYQ?u=https://dec.ny.gov/regulatory/regulations/proposed-emergency-recently-adopted-regulations/water-revisions/saline-water-quality-standards-and-reclassification

2. Joan will re-send draft comments that can be edited however anyone wants if they want to comment: Parcels 1 & 2 of Public Place are being divided up and DEC is planning to investigate using ISS and ISGS at the site. Comment period ends December 5.  

3. Natalie’s Q&As that affect Water Quality were shared in the meeting announcement. We discussed up to number 8. Attendees must go over Natalie’s Q&As to see if there are further questions. Corinne will craft a follow-up regarding continued CSOs in the Canal (Natalie Q.2).

4. DEFERRED: Draft inquiry to EPA [?] re: Sewershed in Gowanus and issues related to the Atlantic Yards Project and the BMT project. Our infrastructure cannot possibly take all that.

Minutes of the December 1, 2025 Meeting of the Gowanus Canal CAG’s Archaeology & Historic Preservation Committee

Attendees: Joan Salome-Rodriguez (Moderator), Katia Kelly, Peter Reich, Jason Schwartzman, Susan Yung

Guests: Irene Baker (National Grid), Aaron Kaufman (Gowanus Remediation Team)

1. Michael was not present but we know that he did explore the NYC Municipal Archives because some of the photos showed up in his Instagram account “Gowanus_Archeology” (there is an underline in there!). Joan and Peter sent materials.  

  • Michael will explore Brooklyn Eagle’s archive for materials 
  • update on Peter & his wife’s work. 
  • Voice of Gowanus archive? We also know that he did access the VOG archive.  
  • Shared https://nycrecords.access.preservica.com/?pg=2&s=gowanus+canal Muni Archive in the chat.  The photos are very good.  Take a look.

2. Check status of the Storyboard with Aaron. Chronicle Heritage is working on setting up an account with a platform for activity. He believes we will have a more certain date in January 2026. He explained the platform, Arts GIS, to Jason – it is a multi-media platform that allows photos, video, text and audio and the Story Map is the Hx of the Gowanus Canal.

3. Peter reported on his conversation with Johnny Thornton (Arts Gowanus) and they are open to us sharing material for the Walkabout Tour. We will start with the building where the CSO tank is going in and get the step by step of how to do it. Seems that getting the photos to Johnny is the key but there may be a cost associated with creating the vinyl posters (plastic and fabric 3’ x 5’) with the QR code (see one by the Carroll St. Bridge). The QR code is a single code that takes one to a website with a map that the viewer uses to find their current location and see what was there before the re-zone. It seems that a lot of this walkabout falls into what we want to focus on, the WAY IT WAS as opposed to the way it is now. Peter will send me Johnny’s email again and I need to sell the idea to him of us sharing stuff. Peter recommends speaking with Andrea at Gowanus Canal Conservancy, too.

4. Through its Gowanus Neighborhood Art Advisory Committee (GNAAC) initiative, Arts Gowanus has made significant inroads working with developers to incorporate public art installations (majority of them by Brooklyn-based artists) at 7 to 8 sites along the Gowanus Waterfront Esplanade; these projects are currently under review by the Department of Parks and Recreation (DPR). Let’s see if Johnny can come to one of our meetings. This may be out of our scope but if there is an appetite for bigger items, maybe John Quadrozzi’s storage items can now be utilized. Also discussed perhaps a historical exhibit at the Gowanus Dredgers 2nd Street space.  If I go to Quadrozzi’s, I want a person to accompany me.

5. On the back burner: Reach out to Brooklyn College Museum Studies Program and to Pratt’s archaeology team in the fall to see if there are any opportunities there. (This was Joan’s action item, not done yet.) Keep an eye on the Union Street Library on Clinton Street to see when it opens (not yet). 

6. Agreed as a committee to build synergy with local arts community and to explore options with new Gowanus Canal Conservancy space, Thomas Greene Park community center.

Summary of Status Updates Presented by EPA at the September General Meeting of the Gowanus Canal Community Advisory Group

RH-034 (CSO retention tank at the head of the canal along Nevins Street)

  • Micropile installation has been completed on the northern half of the tank. Concrete pouring for the base of the tank has begun in this area.
  • Micropile installation is ongoing for the southern half of the tank and is expected to be completed by the end of November, followed by concrete pouring for the base of the tank in this area. 
  • Waterproofing of the tank base and sidewalls is ongoing.
  • A new, larger crane was mobilized to the site last week. It will be used to lower forms into the tank footprint for concrete pouring of the side walls.
  • Construction of the tank (i.e., below-ground construction) is expected to be fully complete by September 2026.
  • New York City Department of Environmental Protection (NYC DEP) staff and their contractors are currently working one shift per day, approximately 8 to 10 hours per shift depending on the length of concrete pouring on any given day.

OH-007 (CSO retention tank at the Owl’s Head Peninsula near 2nd Avenue and 6th Street)

  • Construction of the new composting facility has been completed.
  • Construction of the new salt shed is ongoing, including painting and installation of the wall and roof panels. This is expected to be complete by the end of October. 
  • Perimeter wall construction is ongoing. As of September 30, 132 of 138 perimeter wall panels have been completed. This work is expected to be completed in the next two weeks. 
  • The next phase of work will consist of jet grouting of the panels down to the bedrock layer beneath the site. This is expected to be completed in late winter followed by soil excavation of the tank itself. 
  • NYC DEP staff and their contractors are currently working 24 hours per day Monday through early Saturday morning. This schedule will continue through December before shifting to a two-shift-per-day, eight-hour-per-shift schedule. 

Bulkheads

  • Bulkheads installation along RTA2 (middle section of the canal) is currently in progress. For the properties that the Gowanus Remediation Trust is leading, sheet are 89% done and tiebacks are 49% done. When the Trust finishes their bulkheads, they will move on to the Turning Basin 1 project and the other property owners will complete their bulkhead reconstructions.

Carroll Street Bridge

  • The Carroll Street Bridge construction started in April and is currently underway.
  • Expect the reopening of the bridge in early 2026.

Canal Design

  • The design for RTA2 has been finalized (9/17). Will post on the Site Profile Page in a few days. Natalie Loney will announce when it’s up.

Sheens at Head of the Canal

  • We are still working closely with the Trust to determine the source of the sheens and find a plan to mitigate the issue.
