Regulatory Setting <br />Basin Plan <br />The Central Valley Water Board is required to formulate and adopt Basin Plans for <br />all areas within the Central Valley region under Section 13240 of the Porter- <br />Cologne Water Quality Control Act. Each Basin Plan must contain water quality <br />objectives to ensure the reasonable protection of beneficial uses, as well as a <br />program of implementation for achieving water quality objectives with the Basin <br />Plans. Federal regulations require each state to adopt water quality standards to <br />protect the public health or welfare, enhance the quality of water and serve the <br />purposes of the Clean Water Act. In California, the beneficial uses, water quality <br />objectives, and the Antidegradation Policy are the State's water quality standards. <br />Water quality standards are also contained in the National Toxics Rule, 40 CFR <br />Section 131.36, and the California Toxics Rule, 40 CFR Section 131.38. <br />The Basin Plan is subject to modification as necessary, considering applicable <br />laws, policies, technologies, water quality conditions and priorities. The original <br />Basin Plans were adopted in 1975, and have been updated and revised periodically <br />as required, using Basin Plan amendments. Once the Central Valley Water Board <br />KARL E.
