Section 18 AAC 78.012 - Installation requirements for partially excluded USTs(a) An owner or operator must install a UST listed in 18 AAC 78.005(d)( 1), (3), or (4) storing petroleum, whether of single-wall or double-wall construction, that meets the following requirements: (1) the UST must prevent releases caused by manufacturing defects, corrosion, or structural failure for the operational life of the UST;(2) the UST must be cathodically protected against corrosion, constructed of noncorrodible material, steel clad with a non-corrodible material, or designed to prevent the release or threatened release of stored petroleum; and(3) the UST must be constructed or lined with a material that is compatible with the stored petroleum.(b) Notwithstanding (a) of this section, a UST without corrosion protection may be installed at a site that is determined by a corrosion expert not to be corrosive enough to cause the UST 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.(c) The department encourages use of the following codes of practice as guidance for complying with this section: (1) NACE International Standard Practice RP 0285-2002, External Corrosion Control of Underground Storage Tank Systems by Cathodic Protection, 2002;(2) NACE International Standard Practice SP 0169-2007, Control of External Corrosion on Underground or Submerged Metallic Piping Systems, reaffirmed March 15, 2007;(3) American Petroleum Institute Recommended Practice 1632, Cathodic Protection of Underground Petroleum Storage Tanks and Piping Systems, Third Edition, May 1996; or(4) Steel Tank Institute Recommended Practice R892, Recommended Practice for Corrosion Protection of Underground Piping Networks Associated with Liquid Storage and Dispensing Systems, January 2006.Eff. 9/27/2018,Register 227, October 2018Authority:AS 46.03.020
