§ 66264.191. Assessment of Existing Tank System's Integrity.
(a) Tanks shall have sufficient shell strength and, for closed tanks, pressure controls (e.g., vents) to assure that they do not collapse or rupture. The Department will review the design of the tanks, including the foundation, structural support, seams and pressure controls and seismic considerations. The Department shall require that a minimum shell thickness be maintained at all times to ensure sufficient shell strength. Factors to be considered in establishing minimum thickness include the width, height and materials of construction of the tank, and the specific gravity of the waste which will be placed in the tank. In reviewing the design of the tank and approving a minimum thickness, the Department shall rely upon appropriate industrial design standards and other available information.
(b) For each existing tank system that does not have secondary containment meeting the requirements of section 66264.193, the owner or operator shall determine that the tank system is not leaking or is unfit for use. Except as provided in subsections (d) and (g) of this section, and in addition to the requirements of subsection (f) of this section, the owner or operator shall obtain and keep on file at the facility a written assessment reviewed and certified by an independent, qualified professional engineer, registered in California, in accordance with section 66270.11(d), that attests to the tank system's integrity.
(c) This assessment shall determine that the tank system is adequately designed and has sufficient structural strength and compatibility with the waste(s) to be transferred, stored or treated, to ensure that it will not collapse, rupture, or fail. At a minimum, this assessment shall consider the following:
(B) for other than non-enterable underground tanks and for ancillary equipment, this assessment shall include either a leak test, as described above, or other integrity examination, that is certified by an independent, qualified, professional engineer, registered in California, in accordance with section 66270.11(d), that addresses cracks, leaks, corrosion, and erosion; and
(f) Owners or operators of all existing tank systems shall submit to the Department with Part B of the application for a hazardous waste facility permit, a written statement, signed by an independent, qualified professional engineer, registered in California, in accordance with section 66270.11(d), attesting that the tanks and containment system are suitably designed to achieve the requirements of this article.
(g)(1) Notwithstanding subsections (b) through (d) of this section, for each existing tank system that does not have secondary containment meeting the requirements of section 66264.193 and which meets the criteria specified in subsection (g)(2) of this section, the assessment specified in subsection (i) of this section shall be conducted by January 24, 1998. This assessment shall be reviewed and certified by an independent, qualified, professional engineer, registered in California, in accordance with section 66270.11(d), that attests to the tank system's integrity. The assessment shall be kept on file at the facility until closure of the facility and shall be valid for a period of one year from the date the assessment was certified.
(h) 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, or Conditional Exemption pursuant to HSC 25201.5, operating a non-RCRA underground tank system or an underground tank system otherwise exempt from permitting requirements pursuant to the federal act, shall comply with the applicable standards of Title 23 of the California Code of Regulations relating to underground tank systems.
(9) results of a leak test, internal inspection, or other tank system integrity examination including the type of integrity examination performed (i.e., ultrasonic, internal examination, volumetric tank test, pipeline pressure test). Tank system integrity or leak test requirements must be in compliance with all local requirements. Prior to conducting a tank system integrity test or leak test, contact local agency staff for local requirements.
