In addition to complying with New York City Watershed Regulations, many watershed activities are also subject to the State Environmental Quality Review Act (SEQRA). Under SEQRA, proposed construction activities occurring within a municipal jurisdiction are subject to the review and commentary of other involved agencies to minimize or eliminate potential environmental impacts.
For all projects that trigger the New York City Watershed Regulations, DEP is at least named an “Involved Agency” and may also assume the role of “Lead Agency” where potential impacts to the water supply or surrounding lands are significant. DEP may also be named an “Interested Agency” for those projects not requiring DEP approval but which may affect City-owned watershed properties. DEP monitors the SEQRA status of all projects in the watershed to ensure that water quality concerns are properly raised and thoroughly addressed.
