Newtown Creek Combined Sewer Overflow (CSO) Storage Tunnel Project

CEQR No. 24DEP053Y

Project Description

New York City Department of Environmental Protection (DEP), as lead agency, is preparing an environmental review to disclose potential adverse significant impacts from the construction and operation of 3.26-mile-long CSO storage tunnel, diversion facilities for four outfalls to convey wet-weather flows to the tunnel, a gravity diversion sewer to connect the diversion facility at outfall BB-026 to the tunnel, and a tunnel dewatering pump station (TDPS) and discharge pipe to convey stored sewer overflows to the Newtown Creek Wastewater Resource Recovery Facility (WRRF).The Proposed Project includes the acquisition of sites that is subject to land use approvals under the Uniform Land Use Review Procedure (ULURP). The Proposed Project is being reviewed in accordance with the New York State Environmental Quality Review Act (SEQRA), City Environmental Quality Review (CEQR), and ULURP. The Proposed Project is required under an Order on Consent to address CSOs in New York City, that the City of New York and the New York State Department of Environmental Conservation (NYSDEC) entered into in 2005. As part of the CSO Order on Consent, DEP prepared the Newtown Creek CSO Long-Term Control Plan (LTCP), which the NYSDEC approved in June 2018. Pursuant to the CSO Order on Consent and the LTCP, DEP is now proposing the Proposed Project.

DEP issued a Draft Scope of Work (DSOW) for the Proposed Project on February 5, 2025. A virtual public scoping meeting on the DSOW will be held on March 12, 2025. The public comment period will remain open until April 11, 2025. The DSOW, the Notice of Lead Agency Declaration/Notice of Positive Declaration, and the Environmental Assessment Statement (EAS) are available below.
