| Abstract | Long Description |
Section 303(d) of the federal Clean Water Act requires Washington State periodically to prepare a list of all surface waters in the state for which beneficial uses of the water – such as for drinking, recreation, aquatic habitat, and industrial use – are impaired by pollutants. These are water quality limited estuaries, lakes, and streams that fall short of state surface water quality standards and are not expected to improve within the next two years. Waters placed on the 303(d) list require the preparation of Total Maximum Daily Loads (TMDLs), a key tool in the work to clean up polluted waters. TMDLs identify the maximum amount of a pollutant allowed to be released into a waterbody so as not to impair uses of the water, and allocate that amount among various sources. The technical study to address water quality concerns in Water Resource Inventory Area 45 has been split into two years.
This QA Project Plan describes the technical study that will evaluate temperature, pH, dissolved oxygen, fecal coliform, and other ancillary parameters in tributaries to the Wenatchee River including Mission, Brender, Chiwaukum, Chumstick, Nason, and Peshastin creeks. This TMDL, in combination with the year-one study on the Wenatchee River and Icicle Creek, will set water quality targets to meet water quality standards and allocate pollutant loads to sources. The study will be conducted by the Washington State Department of Ecology, Environmental Assessment Program. |
