Rule 20-5502 - PARTIAL APPLICABILITY OF UST REGULATIONS TO PARTICULAR UST SYSTEMS

5502.1

In addition to any requirements referenced below, the following USTs are required to comply only with the provisions of this section and with Chapters 62 and 67:

(a) Wastewater treatment tank systems not regulated under §§ 307(b) or 402 of the Clean Water Act, 33 USC §§ 1317(b) or 1342;

(b) UST systems containing any radioactive material that is regulated under the Atomic Energy Act of 1954, 42 USC §§ 2011et seq.;

(c) UST systems that are part of any emergency generator system at nuclear power generation facilities licensed by the Nuclear Regulatory Commission and subject to Nuclear Regulatory Commission requirements regarding design and quality criteria, including but not limited to 10 CFR part 50; and

(d) Above ground storage tanks associated with:

(1) Airport hydrant fuel distribution systems regulated under § 5507; and

(2) UST systems with field-constructed tanks that are regulated under § 5507.

5502.2

A person may install an UST system identified in §§ 5502.1(a), (b), or (c) for the purpose of storing any regulated substance only if that UST system:

(a) Will prevent releases due to corrosion or structural failure for the operational life of the UST system;

(b) Is cathodically protected against corrosion, constructed of no ncorrodible material, steel clad with a no n-corrodible material, or designed to prevent the release or threatened release of any stored regulated substance; and

(c) Is constructed or lined with material that is compatible with the stored regulated substance.

5502.3

Notwithstanding the requirements of this section, a person may install an UST system without corrosion protection at a facility that is determined by a corrosion expert to not be corrosive enough to cause the UST system to have a release due to corrosion during its operating life. The owner or operator shall maintain records that demonstrate compliance with the requirements of this subsection for the remaining life of the tank.

5502.4

In the event of a suspected or confirmed release from an UST system listed in § 5502.1, the owner or operator shall comply with §§ 5600, 5602, and 5603, except § 5600.6(d).

5502.5

The following codes of practice may be used to comply with the requirements for partially excluded UST systems in §§ 5502.2 and 5502.3 :

(a) NACE International Standard Practice SP 0285, "External Corrosion Control of Underground Storage Tank Systems by Cathodic Protection";

(b) NACE International Standard Practice SP 0169, "Control of External Corrosion on Underground or Submerged Metallic Piping Systems";

(c) American Petroleum Institute Recommended Practice RP 1632, "Cathodic Protection of Underground Petroleum Storage Tanks and Piping Systems"; or

(d) Steel Tank Institute Recommended Practice R892, "Recommended Practice for Corrosion Protection of Underground Piping Networks Associated with Liquid Storage and Dispensing Systems."
