Current through Vol. 24-12, July 15, 2024
Rule 9. Section 280.20 is amended to read as
						follows:
Section 280.20. Performance standards for new UST
						systems. In order to prevent releases due to structural failure, corrosion, or
						spills and overfills for as long as the UST system is used to store regulated
						substances, all owners and operators of new UST systems shall meet the
						following requirements. In addition, except for suction piping that meets the
						requirements of subparagraphs 280.41(b)(1)(ii)(A) to (E), tanks and piping must
						be secondarily contained and use interstitial monitoring in accordance with
						subsection 280.43(g) of these rules. Secondary containment must be able to
						contain regulated substances leaked from the primary containment until they are
						detected and removed and prevent the release of regulated substances to the
						environment at any time during the operational life of the UST system. For
						cases where the piping meets the definition of "replaced" in section 280.12,
						the entire piping run must be secondarily contained.
(a) Tanks. Each tank must meet the definition
					 of secondary containment as defined in section 280.12 and must be properly
					 designed and constructed. Any portion of a tank that is underground and that
					 routinely contains product must be protected from corrosion by 1 of the
					 following:
(1) The tank must be constructed
					 of fiberglass-reinforced plastic
(2) The tank must be constructed of steel and
					 be cathodically protected by all of the following:
(i) The tank must be coated with a suitable
					 dielectric material.
(ii)
					 Factory-installed or field-installed cathodic protection systems must be
					 designed by a corrosion expert.
(iii) Impressed current systems must be
					 designed to allow a determination of current operating status as required in
					 subsection 280.31(c).
(iv) Cathodic
					 protection systems must be operated and maintained in accordance with section
					 280.31 or according to procedures acceptable to the department.
(3) The tank must be constructed
					 of a steel-fiberglass-reinforced-plastic composite. The fiberglass-reinforced
					 plastic must be a minimum of 100 mils thick.
(4) The tank is constructed of metal without
					 additional corrosion protection measures provided that both of the following
					 requirements are met:
(i) The tank is
					 installed at a site that is determined by a corrosion expert not to be
					 corrosive enough to cause it to have a release due to corrosion during its
					 operating life.
(ii) Owners and
					 operators maintain records that demonstrate compliance with the requirements of
					 paragraph (a)(4)(i) of this section for the remaining life of the
					 tank.
(5) The department
					 shall determine that the tank construction and corrosion protection have been
					 designed to prevent the release or threatened release of any stored regulated
					 substance in a manner that is at least as protective of human health and the
					 environment as the protections specified in subdivisions(1) to (3) of this
					 subsection.
