| Abstract | Long Description |
The Washington State Department of Ecology (Ecology) is required, under section 303(d) of the federal Clean Water Act and U.S. Environmental Protection Agency (EPA) regulations, to develop and implement Total Maximum Daily Loads (TMDLs) for impaired waters. A TMDL analyzes how much pollution a waterbody can assimilate without violating Washington State water quality standards. EPA requires states to set priorities for cleaning up 303(d) listed waters and to establish a TMDL for each. Liberty Bay is located in Kitsap County, south of the city of Poulsbo. Liberty Bay and Johnson, Big Scandia, Little Scandia, Lemolo, Bjorgen, and Barrantes Creeks were listed by Ecology for exceeding fecal coliform (FC) bacteria standards. Additional 303(d) listings exist within the Liberty Bay watershed for various toxic substances, pH, and dissolved oxygen. This TMDL study is limited to FC bacteria. Each TMDL study conducted by Ecology must have an approved Quality Assurance (QA) Project Plan. The plan describes the objectives of the study and the procedures to be followed to achieve those objectives. The objectives include (1) identifying and characterizing FC bacteria concentrations and loads from all major inputs to Liberty Bay (2) and developing target reductions of FC bacteria to support establishing load and wasteload allocations. While the overall goal of the TMDL is to improve water quality in Liberty Bay, this study will focus on the analysis of the freshwater creek and stormwater FC contributions to the bay. Ecology will target freshwater sources most likely to contribute to marine saltwater FC. But the TMDL cannot provide an estimate of the resulting change in FC concentrations in the bay. The Liberty Bay FC TMDL study will be conducted by Ecology′s Environmental Assessment Program. After completion of the study, a final report describing the study results will be posted to the Internet. |
