This chapter is enacted pursuant to authority granted by Sections 13800 to 13806 of the water code of the state of California. However, subsequently the regional water quality control board held a hearing on this chapter pursuant to Section 13804 of the Water Code of the state of California. On October 11, 1974, the county clerk received official notice of the decision of said regional board that this chapter was not sufficiently restrictive to protect the quality of the affected waters on several points, in accordance with said Section 13804. This chapter, as amended, was subsequently reviewed and approved by said regional board and went into effect on February 8, 1975. (Prior code § 7761)
