Reducing Combined Sewer Overflows in NYC – DEP’s Long Term Control Plan
Water Quality Planning Process for Local Waterways
On March 8, 2012, the New York State Department of Environmental Conservation (DEC) and DEP signed a groundbreaking agreement to reduce combined sewer overflows (CSOs) using a hybrid green and gray infrastructure approach. As part of this agreement, DEP will develop 10 waterbody-specific LTCPs plus 1 citywide LTCP to reduce CSOs and improve water quality in NYC’s waterbodies and waterways. The goal of each LTCP is to identify appropriate CSO controls necessary to achieve waterbody-specific water quality standards, consistent with the Federal CSO Policy and the water quality goals of the Clean Water Act (CWA).
