| Short Description |
Section 303(d) of the federal Clean Water Act mandates that the state establish Total Maximum Daily Loads (TMDLs) for surface waters that do not meet standards after application of technology-based pollution controls. The U.S. Environmental Protection Agency (EPA) has promulgated new regulations (40 CFR 130.7 (e) and developed guidance (EPA, 1991) for establishing TMDLs. (Also see abstract below) | |

| Abstract | Long Description |
Section 303(d) of the federal Clean Water Act mandates that the state establish Total Maximum Daily Loads (TMDLs) for surface waters that do not meet standards after application of technology-based pollution controls. The U.S. Environmental Protection Agency (EPA) has promulgated new regulations (40 CFR 130.7 (e) and developed guidance (EPA, 1991) for establishing TMDLs. The Lower Skagit River Total Maximum Daily Load, developed by the Washington State Department of Ecology (Ecology), is being established for oxygen demanding substances, that is carbonaceous 5-day biochemical oxygen demand (CBOD5) and ammonia. This TMDL is being established to prevent impairments to aquatic life from potential low dissolved oxygen concentrations. Since the lower Skagit River currently meets the state dissolved oxygen standard, this TMDL is a basis for planning by the affected dischargers. |
