Small and Rural Community Clean Water Technical Assistance Act This bill amends the Federal Water Pollution Control Act (commonly known as the Clean Water Act) to authorize the Environmental Protection Agency to provide grants or cooperative agreements to qualified technical assistance providers for assisting publicly owned treatment works (POTWs) that are small (serving 10,000 individuals or fewer) or medium (serving no fewer than 10,001 and not more than 75,000 individuals) in size. The technical assistance providers must assist the POTWs in complying with the Act or obtaining financing under the Act for eligible projects. Assistance may be provided to POTWs through onsite technical assistance, circuit rider technical assistance programs, regional technical assistance programs, and onsite and regional training.
