10 CSR 26-2.010 - Applicability

Current through Register Vol. 46, No. 19, October 1, 2021

PURPOSE: There are two (2) primary purposes for this rulemaking. The first is to open UST rules in Title 10, Division 26 of the Code of State Regulations to make the necessary changes required by the U.S. Environmental Protection Agency (EPA). The 2005 Energy Policy Act required either financial responsibility for UST installers and manufacturers or secondary containment for all new systems. In addition, last October, EPA adopted changes to the federal UST regulations that need to be incorporated into state regulation. This rule-making will make the necessary changes to comply with these EPA grant requirements and to incorporate the changes made to the federal regulations.

The second reason is to incorporate state-specific changes. The proposed changes would better ensure that old tanks are still functional enough to remain in use. The changes would better prevent and detect leaks, establish clearer and more detailed new system requirements, and incorporate new technologies. The department will also take this opportunity to clarify ambiguous or confusing language and update industry standard referenced in the regulations.

(1) The requirements of this chapter apply to all owners and operators of an underground storage tank (UST) system as defined in 10 CSR 26-2.012, except as otherwise provided in sections (2)-(4) of this rule. Any UST system listed in section (3) of this rule must meet the requirements of 10 CSR 26-2.011.
(2) The following UST systems are excluded from the requirements of this chapter:
(A) Any UST system holding hazardous wastes listed or identified in the Missouri Hazardous Waste Management Law, sections 260.350-260.434, RSMo, and the rules promulgated thereunder or a mixture of hazardous waste and other regulated substances, except for used oil as defined in 10 CSR 25-11.279;
(B) Any wastewater treatment tank system that is part of a wastewater treatment facility regulated under Section 402 or 307(b) of the Clean Water Act ( 33 U.S.C. 1251 );
(C) Equipment or machinery that contains regulated substances for operational purposes such as hydraulic lift tanks and electrical equipment tanks;
(D) Any UST system whose capacity is one hundred ten (110) gallons or less;
(E) Any UST system that is installed within a vault, if all exterior surface areas of the tank may be visually inspected without removal of backfill, gravel, sand, or other fill material;
(F) Any UST system that contains a de minimis concentration of regulated substances; and
(G) Any emergency spill or overflow containment UST system that is expeditiously emptied after use.
(3) Partial Exclusions. Rules 10 CSR 26-2.020-10 CSR 26-2.053 and closure requirements in 10 CSR 26-2.060-10 CSR 26-2.064 do not apply to any of the following types of UST systems:
(A) Wastewater treatment tank systems not covered in subsection (2)(B) above;
(B) Any UST systems containing radioactive material that are regulated under the Atomic Energy Act of 1954 ( 42 U.S.C. 2011 and following);
(C) Any UST system that is part of an emergency generator system at nuclear power generation facilities licensed by the Nuclear Regulatory Commission and subject to the Nuclear Regulatory Commission requirements regarding design and quality criteria, including but not limited to, 10 CFR Part 50;
(D) Aboveground tanks associated with airport hydrant fuel distribution systems; and
(E) Aboveground tanks associated with field-constructed tanks.
(4) Previously deferred UST systems. Previously deferred airport hydrant fuel distribution systems, tank systems, and field constructed tanks systems must meet one (1) of the following options for compliance:
(A) Option 1. Owners and operators must document that the previously deferred UST is appropriate for continued use by providing proof of compliance with 10 CSR 26-2.020 through 10 CSR 26-2.048; or
(B) Option 2. Permanent closure of the UST system no later than July 1, 2019.
(C) New UST systems installed after July 1, 2017, must meet all requirements at installation.
