DRAFT WATER QUALITY ASSESSMENT POLICY
DRAFT ENSURING CREDIBLE DATA FOR WATER QUALITY MANAGEMENT POLICY
Program Policy 1-11, Chapter 1, Assessment of Water Quality for the Clean Water Act Sections 303(d) and 305(b) Integrated Report: The policy that guides the assessment process for state surface waters is undergoing revision. The purpose of the assessment is to determine the status of state water quality based on water quality standards criteria and available data. The state is required under Section 303(d) of the federal Clean Water Act (CWA) and the implementing regulations (40 C.F.R. 130.7) to periodically prepare a list of waters in which designated uses are impaired, as determined through the use of the water quality standards. The state is also directed to periodically submit other information in accordance with Section 305(b) of the CWA. Ecology is now beginning the process to prepare the 2006 list.
This policy describes how the standards are applied, requirements for the data used, and how to prioritize total maximum daily loads (TMDLs), among other issues.
Significant changes in the updated policy since 2002 include:
|•||Incorporate changes in data quality assurance requirements for data submission as a result of the Water Quality Data Act (WQDA) of 2004.|
|•||Pollutant specific assessment and categorization procedures.|
|•||Additional requirements for the amount of data necessary to place a parameter/segment combination in Category 1 (clean water).|
|•||The environmental information management database will be used to manage most water quality data.|
The draft policies can be found at www.ecy.wa.gov/programs/wq/303d/index.html. Paper copies are also available. The deadline for public comments is 5:00 p.m., Monday, July 10, 2006. Please submit comments in writing to the address below, or at any of the public workshops.
Ecology will host public workshops in six cities across Washington to discuss the draft updated water quality assessment policy and the new credible data policy. Ecology staff will explain the draft policies and the public will have an opportunity to ask questions and share their thoughts with ecology staff and other participants. Participants should also formally submit any comments they have in writing.
Each workshop will be the same, so it is only necessary to attend one.
