Ch. 15,Art. 10-9
<br /> (i)All tank systems,until such time as secondary containment meeting the requirements of this section is
<br /> provided,shall comply with the following:
<br /> (1)for non-enterable underground tanks,a leak test that meets the requirements of section 66265.191(b)(5)
<br /> shall be conducted at least annually;
<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,corrasion,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(�shall be provided for tank systems used to manage hazardous wastes generated
<br /> onsite,and which meet the criteria specified in subsection 0)(2)of this section:
<br /> (A)prior to the tank system or component being placed in service for new tank systems or components;or
<br /> (B)by January 24, 1998 for existing tank systems.
<br /> (2)The provisions of subsection 0)(1)of this section apply only to:
<br /> (A)onground or aboveground tank systems containing only non-RCRA hazardous wastes generated onsite,
<br /> and tank systems authorized under Permit-by-Rule pursuant to Chapter 45 of this division, Conditional Authorization
<br /> pursuant to HSC 25200.3,and Conditional Exemption pursuant to HSC 25201.5,and
<br /> (B)onground or aboveground tank systems containing RCRA hazardous wastes generated onsite, if:
<br /> 1.the owner or operator is a conditionally exempt small quantity generator as defined in 40 CFR section
<br /> 261.5,or a small quantity generator of more than 100 kg but less than 1000 kg per month as defined in 40 CFR
<br /> section 265.201,or
<br /> 2.the owner or operator is not subject to regulation in 40 CFR part 265 pursuant to an exemption in 40 CFR
<br /> section 265.1, but the owner or operator is subject to the standards of this article.
<br /> (k)A generator or owner or operator authorized pursuant to Permit-by-Rule pursuant to Chapter 45 of this
<br /> division,Conditional Authorization pursuant to HSC 25200.3,or Conditional Exemption pursuant to HSC 25201.5,
<br /> operating a non-RCRA underground tank system or an underground tank system otherwise exempt from permitting
<br /> requirements pursuant to the federal act,shall comply with the applicable standards of Title 23 of the California Code
<br /> of Regulations relating to underground tank systems.
<br /> (n Secondary containment for onground or aboveground generator and onsite tier(Permit-by Rule,
<br /> Conditional Authorization,and Conditional Exemption), non-RCRA tank systems or tank systems otherwise exempt
<br /> from permitting requirements pursuant to the federal act,shall consist of any of the devices listed in subsection(d)
<br /> and satisfy the requirements of(e)of this section or consist of any device or combination of devices as approved 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 of wastes out of the tank system before such wastes could migrate to the soil,ground water,or surface
<br /> water at any time during the use of the tank system. The following are examples of tank 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 wit d/ [[[...��� _
<br /> electronic leak detection monitoring;
<br /> (2)troughs or pipe runs with impermeable liners that incorporate the following: �1
<br /> (A)visual monitoring during hours of operation or;
<br /> (B)continuous electronic leak detection monitoring for releases or; DEC 0 8 2016
<br /> (C)sumps located at low 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 pointscEWROMENTAL HEALTH
<br /> that visual monitoring is possible. 9FpsniR f MINT
<br /> (n)A generator or owner or operator authorized pursuant to Permit-by-Rule pursuant to Chapter Sof this
<br /> division,Conditional Authorization pursuant to HSC 25200.3, and Conditional Exemption pursuant to HSC 25201.5,
<br /> operating an onground or aboveground, non-RCRA tank system or a tank system otherwise exempt from permitting
<br /> requirements pursuant to the federal act,that has 18 months or less remaining in service prior to planned closure of
<br /> the tank system, may propose alternatives to retrofitting the tank system with secondary containment. Local agency
