Wetlands Bureau Rulemaking and Process Improvement Effort
fresh water wetland The New Hampshire Department of Environmental Services (NHDES) has been engaged in a significant, multi-year initiative to improve the technical review standards as well as the operation and decision-making processes used by the NHDES Wetlands Bureau (referred to as the "Wetlands Program Rule Making and Process Improvement Effort").

Current Status

NHDES is pleased to announce that the New Hampshire Joint Legislative Committee on Administrative Rules (JLCAR) issued final approval of the new wetland rules on May 17, 2019. This approval was the culmination of a significant, multiyear initiative to improve the technical review standards and decision-making processes of the NHDES Wetlands Bureau through consensus-based rulemaking while ensuring consistency with New Hampshire's wetlands statute and NHDES' mission. The initiative engaged a variety of groups and individuals with diverse interest in wetland rules, including the Associated General Contractors, Local River Advisory Committees (LACs), The Nature Conservancy, New Hampshire Association of Conservation Commissions, New Hampshire Association of Natural Resource Scientists, New Hampshire Farm Bureau, New Hampshire Timberland Owners Association, utility providers, and New Hampshire state agencies such as Fish and Game, the Department of Transportation, and the Department of Natural and Cultural Resources. NHDES activities included substantial outreach, numerous public meetings, several rulemaking hearings, and response to 2,000 comments on the draft rules. The new wetland rules will become effective December 15, 2019. If you have any questions about the new wetlands rules or the process, please contact Mary Ann Tilton at (603) 271-2929 or
