## Abstract

EPA is taking final action to codify in the Agency's regulations changes to the Federal Water Pollution Control Act, also known as the "Clean Water Act" or "CWA," resulting from the Energy Policy Act of 2005. This action modifies the National Pollutant Discharge Elimination System regulations to provide that certain storm water discharges from field activities or operations, including construction, associated with oil and gas exploration, production, processing, or treatment operations or transmission facilities are exempt from National Pollutant Discharge Elimination System permit requirements. This action also encourages voluntary application of best management practices for oil and gas field activities and operations to minimize the discharge of pollutants in storm water runoff and protect water quality.
