Gowanus Canal CAG General Meeting
Tuesday, June 25, 2019
Mary Star of the Sea Senior Apartments, 41 1st Street


Doug Sarno opened the meeting at 6:35. 

A few things to plan for moving forward, along with a couple committee reports, and an update from the EPA.

Project Updates

Brian Carr, EPA, presented the updates.

Things are status quo. There is work starting on the Fulton barrier wall. Public Place work also starting. Half a dozen or so designs and negotiations with property owners for them to replace bulkheads, and we’re trying to coordinate all of these things so they fit together. We’re hopeful that’s going to work out. It will be a challenge for staging area and barges in the canal and things like that. Before I went away there was an order issued to the PRP group to install bulkheads where Flushing Tunnel is, and the property next to the head of the canal at 479 Degraw – those are the only two we don’t expect property owners to do – the property owner at 479 Degraw can do it themselves and it will be easier than what happened at Whole Foods.

For those with a history, it is part of Eastern Effects where the “poonami” video was filmed in 2010. Just next to that is the Bayside property; we have an agreement in principal for them to do their design of the bulkhead once done in September. At 450 Union, where Pig Beach is, they’re in the NYS Brownfields program, and we’re in discussion for them to do a bulkhead. A block from there, Lavender Lake and then Powerhouse are in process. Next to Whole Foods we have a bulkhead design, and then next to Carroll Street we’ve been reviewing that.  

This is an incredible amount of work, and people have special sheet piles coming from Luxembourg and places like that. In the meantime, we’re doing lower bulkheads. Smith Street properties down in Red Hook. The number of things we’re doing that are close to fruition is fairly incredible. These walls can cost $5,000 to $10,000 per linear foot and the canal is 1.8 miles long, so we’re talking about quite a lot of money, and a lot of sheet piling. Various parties are anticipating future rezoning requirements, so we’re talking to them about soft edges, and the GCC and DCP, and we are going to start seeing more Sponge Park-type of edges, and hopefully we can begin transforming the way things are done. 

We have approved the design for the 1st Street Basin, and we’ll work with PRPs later in the year about how to move forward on that. With regard to the tunnel proposal, for the moment our Regional Administrator is very carefully reviewing this, and we had an excellent meeting with him earlier today and are meeting again next week. There are so many complex issues with it, and it will take a while. The mandate we’ve been given is to make sure we do the best we can for the community. With any luck we will complete the various steps we need to take so we can begin dredging a year from now. 

Working with National Grid on the Fulton barrier wall. Some of the barges are so large, it would prevent other barges from entering. We have to work toward that so the Flushing Tunnel outlet can be installed; this is one of the most challenging processes we are facing.

We could work 24 hours a day and still not keep up – the things we have to do to not interrupt business, such as get access, assess before and after conditions.

Gowanus Canal CAG General Meeting
Tuesday, May 28, 2019
Mary Star of the Sea Senior Apartments, 41 1st Street


CAG Facilitator Doug Sarno opened the meeting at 6:35. 

There are two upcoming community meetings of interest: the EPA Superfund Town Hall, sponsored by the CAG with Congresswoman Velazquez on May 29, and the Citizens MGP site meeting with NYS DEC on June 13.

Project Updates

Christos Tsiamis, EPA Remedial Project Manager, presented the updates.

Believe it or not, there is not much to tell you. I was here in February. A lot of work has been taking place these past months. Engineering. Logistics arrangements. It is more complicated from my perspective. Trying to think where we finished last time. A number of design documents – as we mentioned in the last meeting, the most important – next month, we’re going into action mode in the canal. 

First, the construction of the cobbled wall in front of the Fulton MGP site from the top of the canal to Union Street on the east/Park Slope side. There will be a continuous sealed sheet pile wall that will prevent tar from entering the canal from the former Fulton MGP site. This work will be done by GGA, the engineers working with National Grid. This aspect is part of the Record of Decision (ROD) for the Fulton Manufactured Gas Plant site. Starting in June, you’ll notice barges. There will be lots of preparation on the land, the side near the existing bulkheads, surveys, and also construction of a noise barrier that will be placed to accommodate the needs of Eastern Effects [film production studio]. The next couple of months, we’ll have to remove any debris that will be there. There will be barges with equipment there. 

Following that, approximately September to November, there will be equipment in the canal to auger. They will try to soften ground with the silent hydraulic press with no noise and no vibrations, and then along that length from top of canal to Union – this is a lesson learned from the pilot. When we brought in the hydraulic press, we learned it could go at some segments along Whole Foods, and then some that could not advance, so what we had to do was retrofit the press with an auger. It was very, very time consuming, so in discussion with contractors, we plan to do the augering first, and then do the construction. Come November, we will start the 55-foot-long sheet piles from the top of canal to Union Street. Sheet piles will be sealed, and that will be all that we do on that side. They have gotten enough pressure from me to keep to the schedule as much as possible. We will be finished with the Park Slope side by June 2020. The problem for me is at the same time as this wall, sheet piles will be placed at the other wall. This wall will be finished by December 2019. It is beyond my control, so now I’m faced with the situation where there will be many things in that small environment. We will still try to maintain the schedule. There are solutions, but it does present a management problem for us.

At its May 28, 2019 general meeting, the Gowanus Canal Community Advisory Group passed the following resolution calling for greater coordination between the New York City Department of City Planning and the New York City Department of Environmental Protection to address additional loading of contaminated CSO solids that may result from the proposed rezoning of Gowanus, in order to protect the Superfund Remedy.

The resolution, addressed to City Planning Director Marisa Lago and NYCDEP Commissioner Vincent Sapienza, reads as follows:

Resolved, as the proposed Gowanus neighborhood rezoning could impact the Superfund process and remedy through increased loading of contaminated CSO solids in the Canal, the Gowanus CAG hereby requests that the Department of City Planning (NYCDCP) and Department of Environmental Protection (NYCDEP) work closely together to coordinate mitigation of negative impacts. To ensure agency compliance, we further request regular updates on coordination efforts by providing written answers to questions unaddressed at the March 26 [2019] general CAG meeting (below) and responding to our comments on the impacts of the Gowanus Neighborhood Rezoning and Related Actions.

Questions from March 26 CAG Meeting:

  1. Will the proposed increase in density as a result of the rezoning impact the annual volume and frequency of CSO contaminated solids discharged into the Gowanus Canal and throughout the East River and New York Harbor?
  2. How will the timeline and phasing of eventual construction projects as a result of the rezoning impact and overlap with Superfund clean-up efforts?
  3. In order to accurately assess the impact of the proposed rezoning on the Superfund Remedy, will DEP calculate CSO discharge volume and frequency by each CSO-shed, incorporate data from real-time water quality monitoring and data collection, and model impact based on both Projected and Potential development sites in the Gowanus Draft Scope of Work?
  4. Can DEP commit to providing a current and ongoing publicly accessible record of infrastructure upgrades and system improvements as well as a mechanism for tracking proposed mitigation measures identified in the Final Environmental Impact Statement for the Gowanus rezoning?
  5. There have been several infrastructure upgrades that include direct discharge of treated stormwater into the Canal. Their performance needs to be proven in pilot projects, in order to adequately support the Superfund remedy. At the general CAG meeting on March 26, 2019, DEP made a commitment to reporting on monitoring results for Sponge Park and the High-Level Storm Sewer. What is the timeline for these monitoring programs, and when will the CAG have access to the results?
  6. The Superfund Record of Decision specifically requires that new development mitigate additional sewer loads that could compromise the Superfund remedy (p. iii, par. 4). Which City agency(ies) or PRP(s) will be responsible for ensuring compliance with this, or will it be passed to the private developer, as was the case with 363-365 Bond? If so, how will the developer be monitored for compliance?
  7. The Superfund Record of Decision specifically requires that CSO retention tanks are sized to “accommodate projected additional loads to the combined sewer system that result from current and future residential development, as well as periods of high rainfall, including future rainfall increases that may result from climate change” (p. 8, par. 5). How will added density impact plans for the CSO infrastructure required under the Superfund ROD?

At its May 28, 2019 general meeting, the Gowanus Canal Community Advisory Group passed the following resolution requesting independent analysis of the potential for preservation of the entire Gowanus Station building located at 234 Butler Street.

The resolution, addressed to Environmental Protection Agency Region 2 (EPA), the New York City Department of Environmental Protection (DEP), and the Advisory Council on Historic Preservation (ACHP), reads as follows:

Resolved, the Community Advisory Group (CAG) requests that EPA engage independent consultants to conduct further site and engineering analysis investigations with respect to retention in place of the City Of New York Water Supply – Distribution GOWANUS STATION building, located at 234 Butler Street.

The CAG asks for an independent consultant to conduct its own analysis to determine whether DEP’s 234 Butler analysis is on point, preferably a consultant familiar with historic preservation practices, such as Jan Hird Pokorny. The CAG asks that the Gowanus Station building be preserved in its entirety.

Background: A previous resolution regarding the request for an independent engineering analysis of this building was passed by the CAG in March 2018.

The CAG was not able to provide direct Section 106 consultation regarding the proposed Memorandum of Agreement (MOA) between June of 2018 and February, 2019.

The original resolution was drafted by the CAG’s Archaeology Committee. You can download a copy of the full resolution here: Gowanus CAG Resolution_234 Butler_5.28.19.

The New York State Department of Environmental Conservation last week announced that cleanup of the former Citizens Manufactured Gas Plant site at Smith Street and 5th Street, also known as Public Place, will begin in June. The project should be completed in less than two years, with work being performed by contractors on behalf of National Grid, with supervision by NYSDEC.

NYSDEC will host a public discussion about the cleanup activities prior to the start of work. You can drop in any time during the session to ask questions and discuss the project. Details are as follows:

Thursday, June 13th
7:00 p.m. to 9:00 p.m.
PS 372, The Children’s School (Gym Entrance)
291 1st Street
Brooklyn, NY 11215

The Gowanus Canal Community Advisory Group’s Land Use Committee met on Tuesday, May 7, 2019, at the offices of the Gowanus Canal Conservancy, at 543 Union Street.

CAG Members present:

David Briggs
Katia Kelly
Andrea Parker
Peter Reich
Maryann Young
Susan Yung

Item 1

Katia updated group on resolution regarding more cooperation between DCP and DEP.


None required. Resolution will be presented at next CAG meeting for a vote.

Item 2

Peter described a condition next to the Carroll Street Bridge when water is draining out of the high-level storm water outfall and the adjacent CSO during dry weather. Based on conversations with DEP, the probable cause is water flowing into the pipes during high tide and flowing back into the canal during low tide. It’s possible that the tidal gate may be getting blocked with debris, delaying the return flow of the water.


Peter will follow up with DEP.

Item 3

Current communication with and support from CB6 could be better, particularly given the risk that the rezoning presents to the Superfund cleanup remedy.


All agreed that there should be a more proactive dialogue between the CAG and CB6. Dave agreed to reach out to the CB6 Chair and District Manager.

The Gowanus Canal Community Advisory Group’s Land Use Committee met on Wednesday, April 3, 2019, at the offices of the Gowanus Canal Conservancy, at 543 Union Street.

CAG Members present:

Katia Kelly
Hildegaard Link
Andrea Parker
Peter Reich
Sue Wolfe
Maryann Young
Susan Yung


Terri Thompson, National Grid

Item 1

Discussed CAG comments on EIS Scoping for rezoning, and reviewed draft notes for comments prepared by Andrea.

  • Need to pass CAG comments at April 23 CAG meeting in order to present at April 25 EIS scoping hearing.
  • Andrea suggested that CAG comments on scoping should focus on specific impacts to the Superfund remedy, including CSOs and contaminant migration.
  • Katia suggested drawing additional comments from specific CAG resolutions that have been passed, including:
    • Public Place Marine Bollards, January 2019
    • SW Bowne Protection, January 2019
    • Safe Egress, October 2018
    • 1st Street Turning Basin, October 2016
    • Marine Habitat at the Head of Canal and Marine Life, June 2016
    • Ecological Restoration, May 2012
  • Hildegaard suggested directing these comments to DCP Waterfront Director Michael Marrella, and inviting him to a CAG meeting.
  • Terri noted that the most consensus ever seen at a CAG meeting was on March 26, when members were united over CSOs.
  • All agreed that scoping comments should be split into two – one specific to Superfund impacts, and the other covering previous pertinent resolutions above.

Item 2

Discussed DEP/DCP presentation to CAG on March 26.

  • All agreed that presentation by agencies showed an unacceptable lack of coordination
  • Further discussion of need to have all agencies in the same room to discuss impacts of rezoning proposal, and that CB6 should convene this.
  • Discussion of need to ensure that DEP and DCP are meeting regularly, and have a plan to manage compliance with ROD requirement that “redevelopment projects will need to take mitigation measures to prevent or offset additional sewer loadings.” (ROD p 72)
  • All agreed on drafting letter to DEP, DCP and electeds to express that presentation was unacceptable, and to demand a binding legal agreement with the community to ensure compliance with ROD requirement above and monthly updates on coordinated progress at CAG meetings.

The Gowanus Canal was designated a federal Superfund site in 2010, initiating a complex, multi-year clean-up of more than a century’s worth of toxins and other contaminants.

The US Environmental Protection Agency (EPA) has completed a successful pilot dredging and capping of the 4th Street turning basin, and is now turning its sights on the process of cleaning the entirety of the canal, beginning at the head-end near Butler Street, in 2020.

Please join us at a public town hall meeting on May 29 for an important update on the canal clean-up, the future timeline, and an idea of what to expect as the work progresses. Congresswoman Nydia Velázquez will give a keynote, and representatives from the EPA will present a project overview and look-ahead. The public will have an opportunity to ask questions following the presentation.

Please RSVP via Eventbrite.

At PS 133, 610 Baltic Street at 4th Avenue, in Brooklyn.

Gowanus Canal CAG Meeting
Tuesday, April 23, 2019
Mary Star of the Sea Senior Apartments, 41 1st Street


Doug Sarno opened the meeting at 6:35.

Project Updates

Natalie Loney, EPA Community Involvement Coordinator, presented the updates:

There hasn’t been much change since the last report. The 95% design report is due from the City on April 30. The wall design has been finalized. The 4th Street Basin artifacts that were extracted are not going to be disposed of. EPA is in negotiation to store material with a property owner in Red Hook, and those items will stay there safe until final disposition.

Questions & Answers

CAG: Where’s Christos?
EPA: Christos is not here because there aren’t major updates. He sent me instead.

CAG: Was under the impression he would come answer some specific questions at this meeting – sent by email.
EPA: We will work to make sure we have answers.

CAG: Is the EPA going to comment on the Gowanus EIS scoping?
EPA: Yes, it is our intent to comment on the EIS.

CAG: Are you going to testify on Thursday at the Public Scoping meeting?
EPA: We will probably send them in writing – I don’t think we plan to testify.

CAG: One of the questions to Christos was what the process would entail if we needed to amend the ROD (Record of Decision)?
EPA: There have been examples of ROD amendments and things that are a little more involved. I can’t give specifics because it’s speculative. It is determined by the level of complexity around changes to the remedy. A ROD amendment is not necessarily required.

CAG: Some were under the impression that opening the ROD will change things?
EPA: This is a Brian Carr question. We have had Superfund sites before where they had to do an Explanation of Significant Difference (ESD), this does not require reopening the ROD. I don’t know as all of this is still theoretical. EPA is not committing to a path because we have not gotten to that point yet.

CAG: When will work at the north end of the canal begin?
EPA: First section is supposed to begin in the next year or so.

CAG: Including the actual physical work on RTA1?
EPA: I assume it will.

CAG: And the cut-off wall construction?
EPA: I think those things will happen concurrently – if dredging is June 2020, the cut-off wall will be prior to that.

CAG: I know there was a date in the ROD that if the City’s management of sewage wasn’t sufficient, there would be further action, when is that supposed to happen?
EPA: If the bottom of the canal is clean but there is continued CSO, the City has to clean up to the level where it was before the change. It depends on when the tank remedy is implemented. The City would be responsible for cleaning up for the number of years following the monitoring and the EPA will make sure they do that.
