Client Alert – A New Year Brings New DEC Freshwater Regulations

A New Year brings New DEC Freshwater Regulations

(Stay tuned…more substantive analysis to follow)

Freshwater wetlands in New York are regulated by both the Department of Environmental Conservation and the Army Corps of Engineers. New York’s Freshwater Wetlands Act (FWA) was adopted to protect wetlands that were 12.4 acres in size and smaller wetlands that were considered to be of unusual local importance.   

Since the FWA was adopted in 1975, the regulatory jurisdiction of DEC has been determined by the official DEC Wetlands Maps: if a wetland was shown on the map, that wetland area and a hundred-foot-wide “adjacent area” around it were regulated. That regulated area could only be expanded by amending the Wetlands Map. 

In 2022, the Legislature amended the Act to remove the requirement that a wetland be shown on the wetlands map, effective January 1, 2025. DEC estimated that the amendment could extend its regulatory jurisdiction to 1,000,000 acres of wetlands that had not been shown on the DEC Wetland Maps, including smaller wetlands located in or adjacent to Census tracts defined by the Census as “Urban Areas.”. 

Since then, DEC has been working to amend the Freshwater Wetlands regulations (6 NYCRR Part 664) to reflect those changes. 

Early in 2024, it took the unusual step of publishing its preliminary draft regulations for public comment and has held a number of hearings and webinars. In August, it published proposed regulations for hearing and comment. Advocates and stakeholders in the regulated communities submitted extensive comments, noting the impact of the change on activities that may have been under environmental review for years. 

DEC published its Notice of Adoption of the new Part 664 regulations in today’s State Register. 

While the Notice states that “regulated parties must comply immediately beginning on the rule’s proposed effective date of January 1, 2025”, it also announces DEC’s transition policy “to allow fair, expeditious and thorough administrative review of freshwater wetlands permits, consistent with ECL § 70-0103, Uniform Procedures, and to balance environmental and economic interests, consistent with ECL § 24-0103, this rule making provides transition periods for projects that have achieved certain development thresholds prior to January 1, 2025, so that those projects may continue without a new freshwater wetlands jurisdictional determination for a specified time period between 3.5 and 2 years”, and expands the activities eligible for the transition period. 

DEC’s regulatory page offers lots to read, including the text of the new regulations, its response to public comment and other Rulemaking Documents, and (hopefully soon) informational maps developed by DEC and a webinar to explain it all on 1/15/25.
