Regulatory Information & Assistance

One key element of DEP’s Long-Term Watershed Protection Program is a comprehensive regulatory program that strives to minimize the risk of water quality impacts from specific watershed activities and associated development pressures.




NYC Watershed Regulations
Under authority granted by New York State’s Public Health Law, DEP has enacted Watershed Rules and Regulations to protect the existing high quality of the New York City water supply and preserve it from future degradation. Certain regulated projects may require that a permit be issued by the applicable local, City, State or federal agency.

Application Process for Regulatory Approvals
In order to discuss regulated activities in the watershed and better understand New York City regulatory requirements and procedures, prospective applicants are encouraged to meet with DEP staff before developing and submitting their project applications. A pre-application conference can benefit both the applicant and DEP when it comes to understanding and planning the project in its early stages.

Application Guides
To assist watershed residents and communities with preparing regulatory applications for DEP review and approval, and to expedite the project review process overall, DEP has developed a series of Application Guides for specific projects.

SEQRA Review
In addition to complying with New York City Watershed Regulations, many watershed activities are also subject to the State Environmental Quality Review Act. 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.
