Section 303(d)
Under Section 303(d) of the Clean Water Act, states are required to list impaired waterways. An impaired waterway is a waterway in which the pollution control methods set in place are insufficient to maintain or achieve appropriate water quality standards. The state uses water quality data to determine if waterways meet water quality standards. For each waterway listed as impaired under Section 303(d), the state is required to establish a Total Maximum Daily Load (TMDL). TDMLs determine the daily loading capacity for each individual pollutant for a waterbody such that the waterway will meet the standards for that pollutant.[1]
A list of Section 303(d) impaired water ways in California can be found on the State Water Resources Control Board's website.
