  • 2012 Integrated Report Approval Documents

    As a result of the data solicitation period that closed on August 30, 2010, the State Water Board received over 100 data submissions. Each data submission includes multiple data sets for one or more pollutants. Data sources included government agencies, municipalities, environmental groups, citizen groups, and receiving water data from the National Pollutant Discharge Elimination System (NPDES) dischargers.

    State Water Board staff reviewed the completion of submitted data according to the data requirements as described in the Notice of Public Solicitation.

    If information was missing from the data, a request for missing information was sent in October 2010 requesting the missing information to be submitted within 30 days.

    Listing a water body as impaired in California is governed by the Water Quality Control Policy for developing California's Clean Water Act Section 303(d) Listing Policy. The State and Regional Water Boards assess water quality data for California's waters every two years to determine if they contain pollutants at levels that exceed protective water quality criteria and standards. This biennial assessment is required under Section 303(d) of the Federal Clean Water Act.
