​NIH implements a multi-faceted approach to stormwater management incorporating a range of best management practices (BMPs) to control the effects of stormwater and maintain compliance with federal, state, and local requirements. The stormwater program addresses liquid discharges to ground and/or stormwater and soil erosion and pursues objectives to meet the comprehensive compliance requirements of the state National Pollution Discharge Elimination System (NPDES) Phase II program. The Environmental Protection Agency (EPA) Stormwater Phase II Rule establishes a municipal separate storm sewer system (MS4) stormwater management program that is intended to improve the Nation’s waterways by reducing the quantity of pollutants that stormwater picks up and carries into storm sewer systems during storm events​.
