Cal. Code Regs. Tit. 22, § 66265.95 - Monitoring Points and the Point of Compliance

(a) For each regulated unit, the owner or operator shall specify in the water quality sampling and analysis plan the point of compliance at which the water quality protection standard of section 66265.92 applies and at which monitoring shall be conducted. The point of compliance is a vertical surface, located at the hydraulically downgradient limit of the waste management area, that extends through the uppermost aquifer underlying the regulated unit. For each regulated unit, the owner or operator shall specify monitoring points at the point of compliance and additional monitoring points at locations determined pursuant to section 66265.97 of this article at which the water quality protection standard under section 66265.92 of this article applies and at which monitoring shall be conducted.

(b) The waste management area is the limit projected in the horizontal plane of the area on which waste will be placed during the active life of the regulated unit.

(1) The waste management area includes horizontal space taken up by any liner, dike or other barrier designed to contain waste in the regulated unit.

(2) If the facility contains contiguous regulated units and monitoring along a shared boundary would impair the integrity of a containment or structural feature of any of the units, the waste management area may be described by an imaginary line along the outer boundary of the contiguous regulated units if the water quality monitoring program for each unit will enable the earliest possible detection of a release from that regulated unit. This provision only applies to contiguous regulated units that were operating before July 1, 1991.
