National Grid’s contractor, Posillico Environmental, is implementing bulkhead barrier wall construction at the Fulton former Manufactured Gas Plant (MGP) Site consistent with the EPA approved design.   This project consists of the replacement of approximately 880 linear feet of existing bulkheads along the eastern side of the Gowanus Canal from the canal’s head end (at Butler Street) to the Union Street Bridge.  This replacement wall will consist of steel sheet piling with an anchored support system which has been designed to serve as both an environmental barrier and support for the EPA’s planned canal dredging and capping remedy. Mobilization began on August 28, 2019 and barrier wall construction is expected to occur over an approximately 12-month period.  Community air monitoring and construction monitoring for vibration and movement is being performed throughout the project.

Recently Completed Activities

  • Clearing and grubbing of 525 Union Street and end of Right-of-Way at Degraw Street.
  • Installation of soil erosion and sediment controls along 270 Nevins Street (Parcel I) and 525 Union Street.
  • Preparation of staging and laydown areas at  Parcels VI (242 Nevins Street) and VII (234 Butler Street).
  • Installation of fencing along Parcel I building.
  • Locating of utilities along 525 Union Street.
  • Mobilization of equipment and initiation of in-canal pre-clearing of bulkhead alignment.

Ongoing Activities

  • Installation of a noise barrier between the Parcel I building and canal.
  • Continued pre-clearing of bulkhead alignment.
  • Air monitoring.
  • Movement and vibration monitoring at Parcels I, VI, VII, and head end of canal.
  • Noise monitoring.
  • Delivery of certain construction materials.
  • Pre-condition surveys.
  • A tugboat subcontracted by National Grid’s environmental contractor took on water during the heavy rain on Sunday, October 27. The boat was moored and not in use when this occurred. There was no observed environmental impact. The tugboat was removed from the Canal and replaced the following day with another boat. The tug boat is used for supporting the in-water pre-clearing and construction activities for the bulkhead installation.

Upcoming Activities

The  process of constructing the barrier wall has recently been  initiated with the first step of  pre-clearing the wall alignment of debris and other potential obstructions within the canal.  The in-canal pre-clearing activities were  initiated during the week of October 21, 2019 and will take approximately four months complete. 

Community Air Monitoring Plan Summary

Air quality monitoring is being performed consistent with the Community Air Monitoring Plan (CAMP) for the Fulton Site using a MiniRAE 3000+ PID for volatile organic compounds (VOCs) and TSI Dust Trak DRX Dust Meter. No VOC or dust levels have been  detected above Action levels during working hours to date.
