| Description | This policy describes the Quality Assurance (QA) measures, guidance, regulations, and existing policies that help ensure the credibility of data and other information used in agency actions based on the quality of state surface waters. Agency actions include (1) determinations of whether a surface water is supporting its designated use, such as the 303(d) and 305(b) assessment processes, (2) establishment of a Total Maximum Daily Load (TMDL) and the associated load allocations and wasteload allocations, and (3) revisions to water quality standards. This policy is required by the Water Quality Data Act (WQDA) codified in RCW 90.48.570 through 90.48.590. | ||||||
| NOTES | Minor revisions made to original September 2006 policy document to fix outdated web links and make changes for accessibility. No substantive revisions were made. | ||||||
