Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(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) Owners
				  or operators of new tank systems or components shall obtain and submit to the
				  Department, at time of submittal of Part B information, a written assessment,
				  reviewed and certified by an independent, qualified professional engineer,
				  registered in California, in accordance with section
				  66270.11(d),
				  attesting that the tank system has sufficient structural integrity and is
				  acceptable for the transferring, storing and treating of hazardous waste and
				  that the tanks and containment system are suitably designed to achieve the
				  requirements in this article. The assessment shall show that the foundation,
				  structural support, seams, connections, and pressure controls (if applicable)
				  are adequately designed and that the tank system has sufficient structural
				  strength, compatibility with the waste(s) to be transferred, stored or treated,
				  and corrosion protection to ensure that it will not collapse, rupture, or fail.
				  This assessment, which will be used by the Department to review and approve or
				  disapprove the acceptability of the tank system design, shall also include, at
				  a minimum, the following information:
(1)
				  design standard(s) according to which tank(s) and/or the ancillary equipment
				  are constructed;
(2) hazardous
				  characteristics of the waste(s) to be handled;
(3) for new tank systems or components in
				  which the external shell of a metal tank or any external metal component of the
				  tank system will be in contact with the soil or with water, a determination by
				  a corrosion expert of:
(A) factors affecting
				  the potential for corrosion, including but not limited to:
1. soil moisture content;
2. soil pH;
3. soil sulfides level;
4. soil resistivity;
5. structure to soil potential;
6. influence of nearby underground metal
				  structures (e.g., piping);
7.
				  existence of stray electric current;
8. existing corrosion-protection measures
				  (e.g., coating, cathodic protection), and
(B) the type and degree of external corrosion
				  protection that are needed to ensure the integrity of the tank system during
				  the use of the tank system or component, consisting of one or more of the
				  following:
1. corrosion-resistant materials of
				  construction such as special alloys, fiberglass reinforced plastic,
				  etc.;
2. corrosion-resistant
				  coating (such as epoxy, fiberglass, etc.) with cathodic protection (e.g.,
				  impressed current or sacrificial anodes); and
3. electrical isolation devices such as
				  insulating joints, flanges, etc.;
(4) for underground tank system components
				  that are likely to be adversely affected by vehicular traffic, a determination
				  of design or operational measures that will protect the tank system against
				  potential damage;
(5) design
				  considerations to ensure that:
(A) tank
				  foundations will maintain the load of a full tank;
(B) tank systems will be anchored to prevent
				  flotation or dislodgment where the tank system is placed in a saturated zone,
				  or is located within a seismic fault zone subject to the standards of section
				  66264.18(a);
				  and
(C) tank systems will withstand
				  the effects of frost heave; and
(6) those design requirements and factors
				  listed in subsection (a) of this section.
