Long Island Well Program
The Long Island Well Program (6 NYCRR Part 602) contributes to the protection and conservation of available water supplies in Kings, Queens, Nassau, and Suffolk counties. The program regulates water withdrawals for any purpose, other than public water supply, when the total capacity of such a well or wells on one property is over 45 gallons per minute (gpm) (64,800 gallons per day). This includes wells for domestic supply, agriculture, irrigation, open loop geothermal systems, temporary or permanent dewatering wells, and others. Capacity is defined as the total withdrawal of all sources for a facility, independent of how they are plumbed or their designation, such as for redundancy, etc. Capacity is determined by summing the maximum potential withdrawal of all the water source(s), not by the typical or actual withdrawal. See exemptions subsection below for additional information.
Pumpage reports for Long Island Well Permits are due either monthly or annually depending on permit requirements. See below for Long Island Well Program Reporting Forms.
- Fire wells in which no pumping equipment is permanently attached, when such well is installed by a municipal corporation, fire district or duly organized fire company or department is exempt from the Long Island Well Program.
- Note that the permit exemption for agricultural water wells on Long Island was eliminated in 1986 by the introduction of paragraph 7 of ECL § 15-1527.
In order to apply for a Long Island Well permit you will need to submit the appropriate forms to the DEC regional permits office. You may contact the DEC regional permits office with questions about completing the application forms and other required information. Find Region 1 contact information here.
Keep plans flexible until DEC staff review your proposal and comment on its conformance to permit standards. Be willing to adjust your project.
