In-City Water Supply Resiliency

CEQR No. 15DEP029Q

The New York City Department of Environmental Protection (DEP), as lead agency, is preparing an environmental review as a part of its Water Supply Permit renewal with the New York State Department of Environmental Conservation. DEP seeks to disclose any potential adverse significant environmental impacts from renewal of DEP’s existing Water Supply/Water Withdrawal permit and the potential future implementation of temporary treatment systems at DEP’s existing well stations to meet the city’s water supply needs as a supplement to upstate surface water supplies. The project will be reviewed in accordance with the New York State Environmental Quality Review Act (SEQRA) and the City Environmental Quality Review (CEQR) process. DEP has owned, maintained, and operated a groundwater supply system in southeastern Queens since 1996. The Queens groundwater system is comprised of 44 well stations, which house a total of 68 water supply wells. These wells collectively have a permitted capacity of up to a five-year running average of 22,568 million gallons per year or 62 million gallons per day (mgd) with a 24,807 million gallon maximum in any single year or 68 mgd.

A Draft Scoping Document for the In-City Water Supply Resiliency project EIS was issued on May 12, 2017, and distributed for public review and comment. A Final Scope of Work, incorporating changes based on relevant comments received has been issued. The Final Scope of Work and responses to public comments is available here and at the repositories. Additional hard copies are available upon written request to the Contact Person listed below.
