| Abstract | Long Description |
Each study conducted by the Washington State Department of Ecology must have an approved Quality Assurance Project Plan. The plan describes the objectives of the study and the procedures to be followed to achieve those objectives. After study completion, a final report describing the results will be posted to the Internet. A Boatyard Receiving Water Study is being conducted to verify assumptions on metals translators and hardness used in the Boatyard General Permit issue by Ecology in November 2005. The study is required by decision of the Pollution Control Hearing Board. The Boatyard General Permit includes numeric benchmarks for copper that apply to stormwater runoff from boatyards. The permit used several assumptions in setting water quality criteria for freshwater (hardness assumption), estimating the fraction of dissolved metals in the receiving water (metals translators), and accounting for potential effects the receiving water may have on metals toxicity (water effects ratio). The permit used copper as an indicator parameter for lead and zinc, also associated with boatyard runoff. The Boatyard Receiving Water Study will collect samples in three marine and two freshwater areas of Puget Sound in September 2008, January 2009, and May 2009. The samples will be analyzed for total recoverable and dissolved copper, lead, and zinc; and hardness (freshwater). Because the permit to be reissued in August of 2008 will not use water effects ratios, these will not be determined in the study. |
