Clean Water Compliance and Ratepayer Affordability Act of 2015

This bill requires the Environmental Protection Agency (EPA) to carry out a pilot program to facilitate the efforts of at least 15 municipalities to develop and implement integrated plans to meet their wastewater and stormwater obligations under the Federal Water Pollution Control Act (commonly known as the Clean Water Act) in a cost-effective and flexible manner and consistent with the Integrated Municipal Stormwater and Wastewater Approach Framework issued by the EPA in May 2012.

A municipality is eligible to participate in the pilot program if the municipality is: (1) a National Pollutant Discharge Elimination System (NPDES) permit holder or designee; or (2) operating under an administrative order, administrative consent agreement, or judicial consent decree to comply with the requirements of the Clean Water Act.

The EPA may give priority to municipalities seeking to develop and implement an integrated plan that includes approaches that adapt to changed or future uncertain circumstances.

In carrying out the pilot program and in mutual agreement with participating municipalities, the EPA may: (1) extend the allowable NPDES permit term by up to 25 years, (2) modify the implementation terms of a consent decree, and (3) provide additional regulatory flexibility in approving and implementing an integrated plan that includes adaptive approaches.
