In 1996 the Massachusetts Department of Environmental Protection issued this policy to establish clear and consistent guidelines for stormwater management across the state. The standards of this policy, enforced by the Conservation Commission, are intended to prevent untreated discharges to wetlands and waters; preserve hydrologic conditions that closely resemble pre-development conditions; reduce or prevent flooding by managing the peak discharge and volumes of runoff; minimize erosion and sedimentation; reduce suspended solids and other pollutants to improve water quality; and provide increased protection of sensitive natural resources.
