A Brief History of CWA
In 1987, the U.S. Congress amended the Clean Water Act (CWA) to establish a national nonpoint source (NPS) program under §319.1 The statute allows states meeting preliminary criteria to receive federal grant money from the U.S. Environmental Protection Agency (EPA) to address NPS pollution. To be eligible for grants, first, each state must identify and report which of its water bodies have not attained or will not maintain state water quality standards, the sources of nonpoint pollution into those waters, and the potential for remedial action.
