New York's abundant rivers, streams, lakes and coastal waters are used for recreation, fishing, tourism, agriculture and manufacturing. Dams and other infrastructure help us manage our waters.

Though plentiful, the water resources of the state are threatened by chemical contaminants and other pollutants from a wide range of sources.

The Division of Water provides various programs that track the quality of the waters, identify and investigate sources of pollution, control these sources and develop strategies to address water quality threats. DEC programs regulate and provide guidance on water supply withdrawal. DEC also manages floodplains and coastal areas to reduce flood risk to protect New Yorkers from coastal and inland flooding.

SPDES General Permit for Stormwater Discharges from Construction Activity Issued

DEC has issued the State Pollutant Discharge Elimination System (SPDES) General Permit for Stormwater Discharges from Construction Activity (GP-0-20-001). Upon its effective date of January 29, 2020, GP-0-20-001 replaces the previous general permit, GP-0-15-002, which expired on January 28, 2020. DEC announced this general permit in the January 29 issue of the Environmental Notice Bulletin.

Copies of the final GP-0-20-001, fact sheet, and responsiveness summary are available on DEC's Stormwater Permit for Construction Activity web page. This web page also describes how to gain coverage under GP-0-20-001 for planned construction activities.

Water Well Contractor Program Registration Open

DEC's Water Well Contractor Program is currently accepting applications for the Certificate of Registration for the period April 1, 2020 through March 31, 2021. Registration is required by March 31 each year for all water well contractors who drill or repair water wells in New York State. The on-site contractor must be certified for the work that they are conducting (well drilling and/or pump installation). A Preliminary Notice must be filed prior to drilling a well and a Water Well Completion Report must be filed upon completion of water well drilling. For additional information, contact Water Well Program staff at 877-472-2619 or

Annual Water Withdrawal Reporting

The DEC Water Withdrawal Reporting Program is currently receiving water withdrawal reporting data for 2019. Reporting is required by March 31 each year for non-agricultural facilities that have a withdrawal capacity of 100,000 gallons or more per day and agricultural facilities that use 100,000 gallons or more per day (30 day average). Agricultural facilities that use less than 100,000 gallons per day can register by using the annual water withdrawal reporting form. For additional information, contact Water Withdrawal Reporting staff at 518-402-8182 or

Take Survey Regarding WQIP Land Acquisition for Source Water Protection Grant

The Water Quality Improvement Project (WQIP) program provides state funding for various project types, including Land Acquisition for protection of drinking water source areas. DEC is seeking participation in a survey to understand any barriers that would prevent potential applicants from using this funding source and how the state can resolve those issues for future rounds. The survey is available on DEC's WQIP Land Acquisition Projects for Source Water Protection Toolkit web page.

SPDES Compliance and Enforcement Annual Report

The SPDES Compliance and Enforcement Annual Report for state fiscal year 2018/2019 is now available. This report details DEC's compliance and enforcement oversight of facilities permitted under the State Pollutant Discharge Elimination System (SPDES) and those activities relating to New York State's authorizations under the Clean Water Act. The report also provides a summary of sewage releases reported to DEC as required under the Sewage Pollution Right to Know (SPRTK) Act.

Draft Recovery Policy on Building Code and Floodplain Management Administration and Enforcement Posted for Comments

The draft Recovery on Building Code and Floodplain Management Administration and Enforcement is now posted on FEMA's website for a 45-day public review and comment period ending March 6, 2020. Submit comments to Public Assistance at

The intent of this policy is to provide communities with the resources needed to effectively administer and enforce building codes and floodplain management ordinances adopted by state, territorial, tribal, and local governments after a major disaster declaration.

Water Quality Improvement Projects, Nonpoint Source Planning Grant, and Engineering Planning Grants Awarded

Governor Andrew M. Cuomo, as part of the Regional Economic Development Council Awards, announced $93 million for 85 Water Quality Improvement Project (WQIP) grants that will improve water quality, reduce polluted runoff and restore waterbodies and aquatic habitats.

WQIP grants fund projects including municipal wastewater treatment, non-agricultural nonpoint source abatement, land acquisition for source water protection, salt storage, aquatic habitat restoration, and municipal separate storm sewer systems. A full list of awarded WQIP projects is available on DEC's WQIP web page.

Governor Cuomo announced $988,636 for 36 Non-Agricultural Nonpoint Source Planning Grant (NPG) projects to produce planning reports. The goal of the program is to get nonpoint source water quality improvement projects ready for construction and to use the planning report to seek funding through WQIP or other funding entities.

Planning projects funded through NPG include in-waterbody controls for nutrients, green infrastructure, culvert repair and replacement, decentralized wastewater treatment facilities, nature-based shoreline projects, and streambank stabilization. A full list of awarded NPG projects is available on DEC's NPG webpage.


Governor Cuomo announced $3 million for 80 Wastewater Infrastructure Engineering Planning Grant (EPG) projects for the initial planning of eligible Clean Water State Revolving Funding water quality projects.

EPG provides funding to municipalities for engineering and/or consultant fees for engineering and planning services to produce an engineering report. A full list of EPG projects is available on the Environmental Facilities Corporation's EPG webpage (leaves DEC website).

Water Infrastructure Improvement Grants Awarded

Governor Andrew M. Cuomo has announced that the state Environmental Facilities Corporation has awarded more than $416 million through the Water Infrastructure Improvement Act and the Intermunicipal Water Infrastructure Grant program for projects that protect public health or improve water quality. An interactive map of the grant awardees is available on EFC's web page (leaves DEC website).

Division of Water Mission

The Mission of the Division of Water is to protect and conserve the water resources of New York State. This mission is accomplished through a wide range of programs and activities. Some of these are statewide in their scope and apply to all parts of the state. Other efforts are targeted to address water quality and quantity issues in specific regions of the state, focusing on waterbodies or watersheds where these issues are of particular concern. Still other programs target specific contaminants (e.g., mercury) or sources (e.g., stormwater runoff) or impacts (e.g., acid rain) of pollution.
