<br />until(i) All tank systems, suchU nd containment meetithe requirements of this section is
<br />provided, shall comply with the following:
<br />(1) for non -enterable underground tanks, a leak test that meets t 1 (b) (5)
<br />shall be conducted at least annually; 1 'i -A i\J 00
<br />(2) for other than non -enterable underground tanks and for all ancillary equipment, an annual leak test, as
<br />described in paragraph (i)(1) of this section, or an internal inspection or other tank integrity examination by an
<br />independent, qualified, professional engineer, registered in California, that addresses cracks, leaks, corrosion, and
<br />erosion shall be conducted at least annually. The owner or operator shall remove the stored waste from the tank, if
<br />necessary, to allow the condition of all internal tank surfaces to be assessed.
<br />(3) The owner or operator shall maintain on file at the facility a record of the results of the assessments
<br />conducted in accordance with subsections (i)(1) and (i)(2) of this section.
<br />(4) If a tank system or component is found to be leaking or unfit for use as a result of the leak test or
<br />assessment in subsections (i)(1) and (i)(2) of this section, the owner or operator shall comply with the requirements of
<br />section 66265.196.
<br />0)(1) Notwithstanding subsections (a) through (c) of this section, secondary containment that meets the
<br />requirements of subsection (0 shall be provided for tank systems used to manage hazardous wastes generated
<br />onsite, and which meet the criteria specified in subsection 0)(2)ofthis section:
<br />(A) prior to the tank system or component being placed in service for new tank systems or components; or

<br />and satisfy the requirements of(e)of this section nrconsist ofany device orcombination ofdevices aeapproved in
<br />writing by the CUPA, or the Department if there is no CUPA or the CUPA requests that the Department make a
<br />determination, which would satisfy the following minimum requirements:
<br />(1) designed, installed, and operated to prevent any migration of wastes or accumulated liquid out of the
<br />system to the soil, ground water, surface water, or air at any time during the use of the tank system; and
<br />(2) capable of detecting and collecting releases and accumulated liquids until the collected material is
<br />removed.
<br />(m) Ancillary equipment shall be provided with secondary containment as specified in subsection (f) of this
<br />section or an alternative device or devices as approved in writing by the CUPA, or Department if there is no CUPA or
<br />the Department if the CUPA requests that the Department make a determination, which would prevent and/or detect
<br />any release ofwastes out of the tank system before such wastes could migrate to the soil, ground water, or surface
<br />water atany time during the use ofthe tank system. The following are examples oftank system and ancillary
<br />equipment secondary containment alternatives or options that may be proposed for review and approval by the
<br />CUPA:
<br />(1) traditional containment of entire tank system within a bermed containment area with visual and/or
<br />electronic leak detection monitoring;
<br />(2) troughs or pipe runs with impermeable liners that incorporate the following:
<br />VQvisual monitoring during hours ofoperation or;
<br />(8)continuous electronic leak detection monitoring for releases or;
<br />(C)sumps located edlow elevations with leak detection monitors.
<br />(3) double -walled piping with continuous interstitial monitoring or monitoring intervals located at low
<br />elevation points along pipeline;
<br />(4) Double -walled piping with translucent or transparent sections located at low points or low endpoints so
<br />that visual monitoring iopossible.
