Update: April 30, 2020

The Pilot Study performed in the Turning Basin 4 of the Gowanus Canal was successfully completed December 2018.  Since then, the Remedial Design Team (the Team) has incorporated the results and lessons learned from this Pilot Study into the design documents for the remediation of the Remedial Treatment Area 1 (RTA-1) (see map). Since the completion of Turning Basin – 4, the 90% and 100% remedial design documents were submitted to the EPA in September 2019 and February 2020, respectively. The 100% remedial design documents were submitted to the EPA in February 2020. We are currently meeting with EPA to review and discuss their comments to finalize the remediation plan. The schedule anticipates a start of field activities for the Gowanus Canal remedy in approximately the third quarter of 2020.

n the interim, the Team, including the general contractor, will prepare the Support Site property at the corner of Huntington and Smith Streets to support the in-canal work. The contractor will stockpile materials on site to be used in the canal remediation. They will also construct necessary support facilities, like the canal water treatment plant to safely clean and discharge canal waters collected during dredging.

Currently, you may see a large fabric enclosure and miscellaneous construction activities on the property where the Gowanus Support Site is located. These activities are related to the former Citizens MGP Site remediation managed under the NYSDEC program. The Gowanus Canal Team is working collaboratively with the National Grid Citizens Site Team to ensure both activities sharing the same site will be able to operate in coordination and perform their respective duties safely.

HISTORY

The Gowanus Canal was built in the mid-1800s and for many years served as as a major industrial transportation route. Decades of industrial use along the Canal contributed to the Gowanus Canal’s environmental impacts. In addition, contamination flows into the canal from overflows from sewer systems that carry sanitary waste from homes and rainwater from storm drains and industrial pollutants. As a result, on March 4, 2010, EPA added the Gowanus Canal to the National Priorities List of sites.
