Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) Owners or
				  operators of new tank systems or components shall ensure 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 so that it will not collapse, rupture, or fail. The
				  owner or operator shall obtain 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 system has sufficient structural integrity, 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
				  of this article. This assessment shall be obtained prior to placing the tank
				  system in service, and shall be kept on file at the facility. This assessment
				  shall also include, at a minimum, the following information:
(1) design standard(s) according to which the
				  tank(s) and ancillary equipment are or will be 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 is or 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. stray electric current; and,
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 or fiberglass-reinforced plastic;
2. corrosion-resistant coating (such as epoxy
				  or fiberglass) with cathodic protection (e.g., impressed current or sacrificial
				  anodes); and
3. electrical
				  isolation devices such as insulating joints and flanges;
(4) for underground tank system
				  components that are likely to be affected by vehicular traffic, a determination
				  of design or operational measures that will protect the tank system against
				  potential damage; and
(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 dislodgement where the tank system is placed in a saturated zone,
				  or is located within a seismic fault zone; and
(C) tank systems will withstand the effects
				  of frost heave.
