New Aboveground Tanks Holding RCRA Hazardous Waste and UST Systems — For the following types of tank systems, the requirements of 66265.192(h)do not apply: Aboveground tank systems containing RCRA hazardous wastes generated onsite when the owner/operator is subject to the requirements of 40 CFR Part 265. Underground storage tank systems. Prior to placing a new tank system of this type in service, the owner/operator must obtain a written assessment as described below.The assessment must be reviewed and certified by an independent,qualified Cali fo rnia-registered PE 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 Article 10. 122CCR 0-6265.192(a)l The assessment must include the following information: 122CCR§66265.192(a)) ❑ Hazardous characteristics of the waste(s)to be handled; 122CCR§66265.192(a)(2)l ❑ Design standard(s) according to which the tank(s) and ancillary equipment are or will be constructed; 122CCR§66265.192(a)(1)l ❑ Design considerations(i.e.,calculations) to ensure that: ❑ Tank foundations will maintain the load of a full tank; 122C.CR§66265.192(a)(S)(A)l ❑ 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; 122CCR§66265.192(a)(5)18)1 ❑ Tank systems will withstand the effects of frost heave. 122CC11§6626s.192(a)(5)(C)l ❑ For 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: 122CCR§66265.192(1x3)1 ❑ Factors affecting the potential for corrosion, including but not limited to: soil moisture content; soil pH; soil sulfides level; soil resistivity; structure to soil potential; influence of nearby underground metal structures (e.g., piping); stray electric current; and existing corrosion-protection measures (e.g.,coating,cathodic protection). ❑ 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 1 following: corrosion-resistant materials of construction such as special alloys or fiberglass- reinforced plastic; corrosion-resistant coating (e.g., epoxy or fiberglass) with cathodic protection UNI-047-7114 www anidocs.org Rev.01/07/08
