Project Updates
Christos Tsiamis, EPA Remedial Project Manager for the Gowanus Canal cleanup, presented the EPA updates.
EPA has the “no fishing” signs ready, thanks to the State and National Grid. We have the locations the CAG agreed upon, and National Grid will be instructed to place the signs at those locations.
We have started the work for the cutoff wall for the former Fulton manufactured gas plant on the east (Park Slope) side of the canal. National Grid contractors have been working there since late August. It is a big job, there will be a sealed bulkhead that will prevent coal tar from leaking through the sides of the canal. There is a staging area being prepared. There is a clearing operation to remove the debris at the bottom of the canal from the top of Union Street along the sides. We anticipate installation of the wall to begin in early February.
Along with these activities, there was air monitoring, noise and vibration monitoring. There will also be some noise barriers, especially around the Eastern Effects Studio to be responsive of their needs. That work is going well.
On September 30, EPA expects to have the 90% design from the Potentially Responsible Parties (PRPs) for Remedial Target Area 1 (RTA-1) from the top of the canal to the 3rd Street Bridge. We expect to have the 90% design for the detention tank at the upper canal on the east side. These are the detention tanks that under the Record of Decision (ROD) the DEP is required to build. This is the bigger of the two. This is for the clean canal. Both are big designs. They will undergo extensive EPA reviews. We will let you know when we will have schedules.
CAG: Is the First Street Basin part of this design?
EPA: The 100% design is in place for that already. The design of the canal is complex because of different flow rates. A lot of work has gone into that. We’re getting to the end.
There are a number of bulkheads in RTA-1 that have to be built. Some have to be prepared, some have to be finalized, some are submitted. There’s a lot of work for the EPA in the coming months. What has to be constructed is the bulkhead in front of NYC property, including the front of the Flushing Tunnel and in front of the outfall. The bulkheads on the west side south of Douglass will have to be constructed, designed, and reviewed from Douglass to Union in the coming months. For the bulkhead on the west from Union to Carroll, there are two properties, and we have designs that are in various stages for these properties. Carroll to 3rd Street also have to design and build, this is the entire east side.
