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 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.

In response to receiving the pretreatment program, the POTWs were required to develop limitations on pollutants which could affect their treatment plant and collections system. These "local limits" are specific to the Littleton/Englewood Wastewater Treatment Plant. Local limits are reviewed every five years. About 13% of the pretreatment permits in the service area of the Littleton/Englewood Wastewater Treatment Plant are based on local limits.
