The 303(d) List of Impaired Water Bodies

2010 List
Evaluation of Water Quality Conditions for San Francisco Bay Region. Proposed Revisions to federal Clean Water Act Section 303(d) List of Impaired Waters.

On February 11, 2009 the Water Board adopted a Resolution approving staff’s recommendations for proposed additions, deletions and changes to the 303(d) list of impaired water bodies in the San Francisco Bay Region. Staff will now transmit our 303(d) list to the State Water Board, which will approve statewide revisions to the list. On October 11, 2011, the U.S. Environmental Protection Agency issued its final decision regarding the water bodies and pollutants added to California's 2010 303(d) List. You can view and query the final 2010 393(d) list list on the State Board website. For information about the San Francisco Regional Water Board process in preparing the 2010 393(d) list, see the documents below.

Background:

Section 303(d) of the Federal Clean Water Act requires that states develop a list of water bodies that do not meet water quality standards, establish priority rankings for waters on the list, and develop action plans, called Total Maximum Daily Loads (TMDL), to improve water quality. The list of impaired water bodies is revised periodically (typically every two years). Read the 303(d) listing policy here. 2006 List The State Water Resources Control Board compiled the 2006 303(d) list based on recommendations from the Regional Water Boards and information solicited from the public and other interested parties. On October 25, 2006, the State Board adopted the California 2006 Revised 303(d) List. On November 30, 2006, US EPA gave partial approval to California's 2006 Section 303(d). On June 28, 2007, the EPA gave a final approval to the list. 2006 CWA Section 303(d) List of Water Quality Limited Segments Approved by US EPA June 28, 2007 (PDF File) US EPA's Partial Approval Letter US EPA's Review Document - Describes the rationale for US EPA's partial approval.
