New York City CSO
Consent Order, Long-Term Control Plans, and Green Infrastructure
New York City Department of Environmental Protection (DEP) is required under a 2005 Order on Consent to reduce combined sewer overflows (CSOs) from its sewer system to improve the water quality of its surrounding waters, such as Flushing Bay, Jamaica Bay, and tributaries to the East River, Long Island Sound, and Outer Harbor.
Under the 2005 Consent Order, the DEP has completed Waterbody/Watershed Facility Plans, which are the initial phase of CSO planning, and are required to construct various grey infrastructure projects, and develop Long-Term Control Plans.
In 2011, the New York State Department of Environmental Conservation (DEC) and DEP identified numerous modifications to the CSO Consent Order, including integration of green infrastructure and substitution of more cost-effective grey infrastructure, and agreed to fixed dates for submittal of the Long-Term Control Plans.
