The objective of this Act is to restore and maintain the chemical, physical and biological integrity of the Nation’s waters (33 U.S.C. 1251). The Act has been amended numerous times and given a number of titles and codification. It was originally enacted as the Water Pollution Control Act in 1948 (P.L. 80-845), and was completely revised by the 1972 amendments, the Federal Water Pollution Control Act Amendments (P.L. 92-500). The 1972 amendments gave the Act its current form, and established a national goal that all waters of the U.S. should be fishable and swimmable. The goal was to be achieved by eliminating all pollutant discharges into waters of the U.S. by 1985 with an interim goal of making the waters safe for fish, shellfish, wildlife and people by July 1, 1983 (86 Stat. 816, 33 U.S.C. 1251) . The 1977 amendments (the Clean Water Act of 1977 (P.L. 95-217)) gave the Act its current title. Additional amendments were enacted in 1981 (Municipal Wastewater Treatment Construction Grants Amendments (P.L. 97-117)) and in 1987 (Water Quality Act of 1987 (P.L. 100-4). The Act regulates discharges to waters of the United States through permits issued under the National Pollutant Discharge Elimination System (NPDES) permitting program.”
