Section 303(d) of the Clean Water Act (CWA) requires that states assess surface waters and compile a list of those that have become polluted to the point that they no longer support their Use Classification (e.g., Fish & Wildlife, Public Water Supply, Swimming & Whole-body Contact, etc.). This list of impaired waters is known as the 303(d) List.
The 303(d) List must be submitted by the states to the U.S. EPA on April 1 of every even-numbered year. The 303(d) List contains details for each impaired waterbody, including the waterbody name, type of waterbody, locational information, the Use Classification of the waterbody, the cause(s) and source(s) of impairment, the area of impairment, the year that the waterbody was first listed, and the year that a draft TMDL is scheduled to be completed for that waterbody.
