Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Under Section 303(d) of the CWA, states, territories, and authorized tribes (referred to</SPAN></P><P><SPAN>here as states) are required to develop lists of impaired waters. These are waters that are</SPAN></P><P><SPAN>too polluted or otherwise degraded to meet the state water quality standards. The law</SPAN></P><P><SPAN>requires that these jurisdictions establish priority rankings for waters on the lists and</SPAN></P><P><SPAN>develop TMDLs for these waters. A Total Maximum Daily Load, or TMDL, is a calculation of</SPAN></P><P><SPAN>the maximum amount of a pollutant that a waterbody can receive and still safely meet</SPAN></P><P><SPAN>water quality standards</SPAN></P></DIV></DIV></DIV>
