| Abstract | Long Description |
The South Fork Palouse River has been listed by the state of Washington under Section 303(d) of the Clean Water Act for non-attainment of Washington State dissolved oxygen (DO) and pH criteria. The listings are based on sampling done by the Washington State Department of Ecology in 1987, 1991, and 1994-2001. Additional 303(d) listings exist within the South Fork Palouse River watershed for temperature, fecal coliform bacteria, and ammonia. EPA requires states to set priorities for cleaning up 303(d) listed waters and to establish a Total Maximum Daily Load (TMDL) for each. A TMDL entails an analysis of how much of a pollutant load a waterbody can assimilate without violating water quality standards. The South Fork Palouse River TMDL Study will address the 303(d) listings within the watershed with three separate Quality Assurance (QA) Project Plans: one for bacteria, one for temperature, and one for DO and pH. This QA Project Plan describes the technical study that will monitor DO and pH in the South Fork Palouse River Watershed, and will form the basis for a proposal to allocate contaminant waste loads to sources. The study will be conducted by Ecology′s Environmental Assessment Program. |
