Citywide & East River/Open Water CSO Long Term Control Plan

The Citywide Long Term Control Plan will encompass the majority of New York’s harbor including the Hudson River, Harlem River, Upper New York Bay, Lower New York Bay, the East River, and the western portion of Long Island Sound. Whale sightings and increases in recreational activity show that the New York Harbor is making a comeback and the signs are all around. According to the city’s most recent Harbor Survey Report, the Harbor is cleaner now than at any time in the last 100 years. Continued improvements to the City’s 14 Wastewater Treatment Plants, and ongoing investments have resulted in an 80% reduction in combined sewer overflows since the mid-1980s. DEP is currently working on a Citwide Long Term Control Plan (LTCP) to better understand how existing CSOs impact water quality in throughout the Harbor. The Citywide LTCP is due in December 2018 and will include a public participation process. Check back here for updates.
