(m)) Ancillary equipment shall be provided with secondary containment as specified in subsection (1) of this section or an alternative device or devices as approved in writing by the COPA, or Department if there is no COPA or the Department if the COPA requests that the Department make a determination, which would prevent and/ordetect any release of wastes out of the tank system before such wastes could migrate to the soil, ground water, or surface water at any time during the use of the tank system. The following are examples of tank system and ancillary equipment secondary containment alternatives or options that may be proposed for review and approval by the COPA: (1) traditional containment of entire tank system within a bermed containment area with visual and/or electronic leak detection monitoring; (2) troughs or pipe runs with impermeable liners that incorporate the following: (A) visual monitoring during hours of operation or, (8) continuous electronic leak detection monitoring for releases or, (C) sumps located at low elevations with leak detection monitors. (3) double-walled piping with continuous interstitial monitoring or monitoring intervals located at low elevation points along pipeline; (4) Double-walled piping with translucent or transparent sections located at low points or low endpoints so that visual monitoring is possible. n (n) A generator or owner or operator authorized pursuant to Permit-by-Rule pursuant to Chapter 45 of this division, Conditional Authorization pursuant to HSC 25200.3, and Conditional Exemption pursuant to HSC 25201.5, operating an onground or aboveground, non-RCRA tank system or a tank system otherwise exempt from permitting requirements pursuant to the federal act, that has 18 months or less remaining in service prior to planned closure of the tank system, may propose alternatives to retrofitting the tank system with secondary containment. Local agency requirements must be considered when proposing alternatives to secondary containment. The owner or operator shall provide the following information in writing to the COPA, or the Department if there is no COPA or the CUPA requests that the Department make a determination, so that a determination can be made whether the proposed alternative would be acceptable: (1) name, address, and EPA identification number of the facility; (2) date of planned closure; (3) description of tank system to be closed and form of current authorization for the tank system; (4) description of how the proposed alternative would provide adequate environmental protection such that the design, installation, and operation will be capable of detecting a release and preventing any migration of wastes or accumulated liquid out of the system to the soil, ground water, surface water, or air at any time during the remaining life of the tank system.
