Stormwater Inspections
Delaware's NPDES Construction General Permit is administered by DNREC's Sediment and Stormwater Program and covers construction activities disturbing one or more acres. The permit integrates closely with Delaware's Sediment and Stormwater Regulations, requiring approved sediment and stormwater plans. Delaware's low-lying coastal geography requires particular attention to managing construction runoff to protect sensitive estuarine waters.
