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"). Check this page often for new information, draft administrative rules, new and draft BMP manuals, scheduled public input sessions and events, and to provide comments and ideas!

Current Status

On September 28, 2018, NHDES filed the initial proposals of the rules with the Office of the Legislative Budget Assistant to begin the formal rulemaking process. NHDES held seven formal rulemaking hearings in December 2018, during the second public comment period. NHDES collated the nearly 2,000 comments received during these hearings and 85 separate letters, and verified that they had been addressed during January and February 2019, creating a final proposed version of the rules during that process. On March 20, 2019, the final proposed rules were submitted to the Joint Legislative Committee on Administrative Rules (JLCAR) for their review. On April 26, 2019 and May 3, 2019, JLCAR approved Shoreland Rules Section Env-Wq 1405.02-03 and Wetland Rules Chapters Env-Wt 100, 200, 400 through 900. On May 17, 2019, the final chapter of the final proposed rules, Env-Wt 300 was approved by JLCAR, completing the process. If you have any questions about the proposed wetlands rules or the process, please contact Mary Ann Tilton at (603) 271-2929 or
