Clean Water Act
The Federal Water Pollution Control Act was amended in 1977. These amendments are also known as the Clean Water Act (CWA). The overall framework of the National Pretreatment Program is contained in the General Pretreatment Regulations that EPA published in 1977. The General Pretreatment Regulations can be found in 40CFR 403.
The amendments required the local Publicly Owned Treatment Works (POTWs) with capacities greater than 5 million gallons per day or those with significant industrial discharges to establish pretreatment programs. In other words, the administration of the Pretreatment Program was delegated from EPA to the local level.
The decision to delegate the Pretreatment program to the local POTWs was based on several factors. First, EPA realized it was having a difficult time implementing the Pretreatment program. Second, POTW officials are familiar with their industrial users. Third, the POTWs are in better position to understand and correct problems within their own treatment systems. Finally, the POTW is the logical level of government to respond to emergencies in the treatment system.
How the Program Works
All permitted industries get inspected. Permitted industries include, but are not limited to; electroplaters, laundries, restaurants, automotive repair shops, photofinishers, carwashes, dry cleaners, radiator shops, etc. Depending on the permit issued, a facility may be inspected up to four times a year.
