SUMMARY: The Department will ensure that activities and plans approved under its authority will employ stormwater management plans utilizing best management practices to control the volume, rate and water quality of post construction stormwater runoff so as to protect and maintain the chemical, physical and biological properties of waters of the Commonwealth. These best management practices must, at a minimum, protect and maintain water resources, preserve water supplies, maintain stream base flows, preserve and restore the flood carrying capacity of waters, preserve to the maximum extent practicable the natural stormwater runoff regimes and natural course, current and cross section of waters of the Commonwealth, and protect and conserve ground waters and ground-water recharge areas.
