To authorize the incorporation of water quality improvement partnership programs into Federal Water Pollution Control Act NPDES permit programs, and for other purposes.

This bill amends the Federal Water Pollution Control Act (commonly known as the Clean Water Act) by allowing a National Pollutant Discharge Elimination System permit program to incorporate a water quality improvement partnership program that encourages investment by publicly owned treatment works and municipal separate storm sewer systems in watershed-based projects for improving water quality. Those partnerships may be used by publicly owned treatment works and municipal separate storm sewer systems to attain and maintain water quality standards.
