Cal. Water Code - WAT § 13800. Section 13800.

The department, after the studies and investigations pursuant to Section 231 as it finds necessary, on determining that water well, cathodic protection well, and monitoring well construction, maintenance, abandonment, and destruction standards are needed in an area to protect the quality of water used or that may be used for any beneficial use, shall so report to the appropriate regional water quality control board and to the State Department of Public Health. The report shall contain the recommended standards for water well, cathodic protection well, and monitoring well construction, maintenance, abandonment, and destruction as, in the department’s opinion, are necessary to protect the quality of any affected water.

Cal. Water Code - WAT § 13800.5. Section 13800.5.

(a) (1) The department shall develop recommended standards for the construction, maintenance, abandonment, or destruction of geothermal heat exchange wells. (2) Until the department develops recommended standards pursuant to paragraph (1), a local enforcement agency with authority over geothermal heat exchange wells may adopt temporary regulations applicable to geothermal heat exchange wells that the local enforcement agency determines to be consistent with the intent of existing department standards to prevent wells from becoming conduits of contamination. (3) The department, not later than July 1, 1997, shall submit to the state board a report containing the recommended geothermal heat exchange well standards. (b) The state board, not later than January 1, 1998, shall adopt a model geothermal heat exchange well ordinance that implements the recommended standards developed by the department pursuant to subdivision (a). The state board shall circulate the model ordinance to all cities and counties. (c) Notwithstanding any other provision of law, each county, city, or water agency, where appropriate, not later than April 1, 1998, shall adopt a geothermal heat exchange well ordinance that meets or exceeds the recommended standards developed by the department pursuant to subdivision (a). If a water agency that has permit authority over well drilling adopts a geothermal heat exchange well ordinance that meets or exceeds the recommended standards developed by the department pursuant to subdivision (a), a county or city shall not be required to adopt an ordinance for the same area. (d) If a county, city, or water agency, where appropriate, fails to adopt an ordinance that establishes geothermal heat exchange well standards, the model ordinance adopted by the state board pursuant to subdivision (b) shall take effect on May 1, 1998, and shall be enforced by the county or city and have the same force and effect as if adopted as a county or city ordinance.

Cal. Water Code - WAT § 13801. Section 13801.

(a) The regional board, upon receipt of a report from the department pursuant to Section 13800, shall hold a public hearing on the need to establish well standards for the area involved. The regional board may hold a public hearing with respect to any area regardless of whether a report has been received from the department if it has information that standards may be needed. (b) Notwithstanding subdivision (a), the state board shall, not later than September 1, 1989, adopt a model water well, cathodic protection well, and monitoring well drilling and abandonment ordinance implementing the standards for water well construction, maintenance, and abandonment contained in Bulletin 74-81 of the department. If the model ordinance is not adopted by this date, the state board shall report to the Legislature as to the reasons for the delay. The state board shall circulate the model ordinances to all cities and counties. (c) Notwithstanding any other law, each county, city, or water agency, where appropriate, shall, not later than January 15, 1990, adopt a water well, cathodic protection well, and monitoring well drilling and abandonment ordinance that meets or exceeds the standards contained in Bulletin 74-81. Where a water agency that has permit authority over well drilling within the agency adopts a water well, cathodic protection well, and monitoring well drilling and abandonment ordinance that meets or exceeds the standards contained in Bulletin 74-81, a county or city shall not be required to adopt an ordinance for the same area. (d) If a county, city, or water agency, where appropriate, fails to adopt an ordinance establishing water well, cathodic protection well, and monitoring well drilling and abandonment standards, the model ordinance adopted by the state board pursuant to subdivision (b) shall take effect on February 15, 1990, and shall be enforced by the county or city and have the same force and effect as if adopted as a county or city ordinance. (e) The minimum standards recommended by the department and adopted by the state board or local agencies for the construction, maintenance, abandonment, or destruction of monitoring wells or class 1 hazardous injection wells shall not be construed to limit, abridge, or supersede the powers or duties of the State Department of Public Health in their application of standards to the construction, maintenance, abandonment, or destruction of monitoring wells or class 1 hazardous injection wells at facilities that treat, store, or dispose of hazardous waste or at any site where the State Department of Public Health is the lead agency responsible for investigation and remedial action at that site, as long as the standards used by the State Department of Public Health meet or exceed those in effect by any city, county, or water agency where appropriate, responsible for developing ordinances for the area in question.

Cal. Water Code - WAT § 13802. Section 13802.

If the regional board finds that standards of water well, cathodic protection well, and monitoring well construction, maintenance, abandonment, and destruction are needed in any area to protect the quality of water used, or which may be used, for any beneficial use, it shall determine the area to be involved and so report to each affected county and city in the area. The report shall also contain any well standards which have been recommended by the department.

Cal. Water Code - WAT § 13803. Section 13803.

Each such affected county and city shall, within 120 days of receipt of the report, adopt an ordinance establishing standards of water well, cathodic protection well, and monitoring well construction, maintenance, abandonment, and destruction for the area designated by the regional board. Prior to adoption of the ordinance each affected county and city shall consult with all interested parties, including licensed well drillers. A copy of the ordinance shall be sent to the regional board on its adoption and the regional board shall transmit the ordinance to the department for its review and comments.

Cal. Water Code - WAT § 13804. Section 13804.

Such county and city well standards shall take effect 60 days from the date of their adoption by the county or city unless the regional board, on its own motion, or on the request of any affected person, holds a public hearing on the matter and determines that the county or city well standards are not sufficiently restrictive to protect the quality of the affected waters. If the board makes such a determination it shall so report to the affected county or city and also recommend the well standards, or the modification of the county or city well standards, which it determines are necessary.

Cal. Water Code - WAT § 13805. Section 13805.

If a county or city fails to adopt an ordinance establishing water well, cathodic protection well, and monitoring well construction, maintenance, abandonment, and destruction standards within 120 days of receipt of the regional board’s report of its determination and those standards are necessary pursuant to Section 13802, or fails to adopt or modify those well standards in the manner determined as necessary by the regional board pursuant to Section 13804 within 90 days of receipt of the regional board’s report, the regional board shall adopt standards for water well, cathodic protection well, and monitoring well construction, maintenance, abandonment, and destruction for the area. The regional board well standards shall take effect 30 days from the date of their adoption by the regional board and shall be enforced by the city or county and have the same force and effect as if adopted as a county or city ordinance.

Cal. Water Code - WAT § 13806. Section 13806.

Any action, report, or determination taken or adopted by a regional board or any failure of a regional board to act pursuant to this article, or any county or city ordinance in the event of the failure of a regional board to review such ordinance pursuant to Section 13804, may be reviewed by the state board on its own motion, and shall be reviewed by the state board on the request of any affected county or city, in the same manner as other action or inaction of the regional board is reviewed pursuant to Section 13320. The state board has the same powers as to the review of action or inaction of a regional board or of a county or city ordinance under this article as it has as to other action or inaction of a regional board under Section 13320, including being vested with all the powers granted a regional board under this article, with like force and effect if it finds that appropriate action has not been taken by a regional board. Any action of a regional board under this article or any county or city ordinance affected by the review of the state board shall have no force or effect during the period of the review by the state board.
