On June 24, 2025, the Region issued an Administrative Compliance Order to the town for violations of the Massachusetts MS4 Permit requirement to enact a post-construction stormwater management ordinance, by-law, or other regulatory mechanism. The Order cites the town's failure to develop or modify, as appropriate, a post-construction stormwater management ordinance within three (3) years of the effective date of the Permit (i.e., by July 1, 2022). The Order requires the town to enact a post-construction stormwater management ordinance or other regulatory mechanism by December 31, 2025. The town must then notify EPA that such an ordinance or regulatory mechanism has become effective within 7 days of its effective date and provide the Agency with a copy of its regulatory mechanism. The Order will facilitate the reduction of pollutants found in their stormwater through the retention or treatment of stormwater after construction on new or redeveloped sites. The Region coordinated with the Massachusetts Department of Environmental Protection (MassDEP) on this matter.
