Stormwater Inspections
Maryland's General Permit No. 20-CP for stormwater from construction activities is administered by the Maryland Department of the Environment. The permit requires compliance with Maryland's stormwater management standards and Environmental Site Design principles. As a Chesapeake Bay watershed state, Maryland imposes additional requirements to reduce nutrient and sediment loading to the Bay.
