Environmental Reviews

In-City Water Supply Resiliency

CEQR No. 15DEP029Q

The New York City Department of Environmental Protection (DEP), as lead agency, is preparing a voluntary environmental review for the In-City Water Supply Resiliency Project, which includes 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. The purpose of the project is to meet the City’s water supply needs in times of upstate water supply shortage due to drought and planned and/or unplanned unforeseen system infrastructure outages. DEP seeks to identify and disclose any potential adverse significant environmental impacts from the Proposed Project. The Proposed Project will not alter current water supply operations and would be employed only under the limited circumstances described in this Draft Environmental Impact Statement (DEIS). The project was 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 and responses to public comments were issued on October 11, 2017. The voluntary Draft Environmental Impact Statement (DEIS) was issued on November 9, 2017. The DEIS is available here and at the repositories listed below. Additional hard copies are available upon written request to the contact person listed below. Written comments will be accepted and the public comment period will remain open until at least 10 days after the last public hearing.

Public Meetings

DEP will hold public meetings to receive comments on the In-City Water Supply Resiliency Draft EIS at dates and locations to be determined. The public comment period will remain open until at least 10 days after the last public hearings is scheduled.
