The Federal Clean Water Act (CWA) requires that California report on the quality of its surface waters every two years. Known as the California Integrated Report, it is the result of a collaborative process between the State and Regional Water Boards. California surface waters are assessed to determine if they contain pollutants at levels that exceed protective water quality standards. The two major components of the Integrated Report are the 305(b) condition report and the 303(d) list of impaired waters.
The 305(b) Report assigns an Integrated Report Condition Category to all assessed waterbody segments. Data are used to evaluate the most common beneficial uses, such as drinking water supply or fish consumption. Waterbody segments that exceed protective water quality standards are placed on the 303(d) List of impaired waters. Placing a waterbody on the 303(d) List initiates the development of a Total Maximum Daily Load (TMDL). In some cases other regulatory programs will address the impairment instead of a TMDL.
All readily available data and information is reviewed and assessed using the Water Quality Control Policy for developing California’s Clean Water Act section 303(d) List (Listing Policy). The Integrated Report must ultimately be approved by U.S. EPA. |
