Cal. Code Regs. tit. 22 § 66264.91

Current through Register 2024 Notice Reg. No. 25, June 21, 2024
Section 66264.91 - Required Programs
(a) An owner or operator subject to this article shall conduct a monitoring and response program for each regulated unit at the facility as follows:
(1) the owner or operator shall institute a detection monitoring program under section 66264.98 except as required under subsections (a)(2), (a)(3) and (a)(4) of this section;
(2) the owner or operator shall institute an evaluation monitoring program under section 66264.99 whenever there is statistically significant evidence of a release, pursuant to section 66264.98(g) or (i), from the regulated unit during a detection monitoring program;
(3) the owner or operator shall institute an evaluation monitoring program under section 66264.99 whenever there is significant physical evidence of a release from the regulated unit. Significant physical evidence of a release includes unexplained volumetric changes in surface impoundments, unexplained stress in biological communities, unexplained changes in soil coloration, visible signs of leachate migration, unexplained water table mounding beneath or adjacent to the regulated unit, and any other change to the environment that could reasonably be expected to be the result of a release from the regulated unit; and
(4) the owner or operator shall institute a corrective action program under section 66264.100 when the Department determines pursuant to section 66264.99 that the assessment of the nature and extent of the release and the design of the corrective action program have been satisfactorily completed and the Department approves the application for a permit modification for corrective action submitted by the owner or operator during an evaluation monitoring program pursuant to section 66264.99(d) or section 66265.99(d).
(b) The Department shall specify in the facility permit the specific elements of each monitoring and response program. For each regulated unit, the Department shall include one or more of the programs identified in subsection (a) of this section in the facility permit as may be necessary to protect human health or the environment and shall specify the circumstances under which each of the programs will be required. In deciding whether to require the owner or operator to be prepared to institute a particular program, the Department shall consider the potential adverse effects on human health or the environment that might occur before final administrative action on a permit modification application to incorporate such a program could be taken.
(c) In conjunction with an evaluation monitoring program or a corrective action program, the owner or operator shall continue to conduct a detection monitoring program under section 66264.98 as necessary to provide the best assurance of the detection of subsequent releases from the regulated unit.
