(a) The owner or operator of a UST with spill and overfill prevention equipment and containment sumps used for interstitial monitoring of piping must meet the following requirements to ensure that the equipment is operating properly and will prevent releases to the environment:

(1) spill prevention equipment, such as a catchment basin, spill bucket, or other spill containment device, and containment sumps used for interstitial monitoring of piping must prevent releases to the environment by meeting one of the following requirements:

(A) the equipment must be double-walled and the integrity of both walls must be periodically monitored at a frequency not less than the frequency of the walkthrough inspections described in 1 8 AAC 78.058; an owner or operator must begin meeting (B) of this paragraph and conduct a test not later than 30 days after discontinuing periodic monitoring of this equipment; or

(B) to ensure that the equipment is liquid-tight, the spill prevention equipment and containment sumps used for interstitial monitoring of piping must be tested at least once every three years by using vacuum, pressure, or liquid testing in accordance with one of the following criteria:

(i) requirements developed by the manufacturer, if the manufacturer has developed requirements;

(ii) a nationally recognized code of practice; or

(iii) requirements determined by the department to be no less protective of human health and the environment than the requirements listed in (i) and (ii) of this subparagraph;

(2) overfill prevention equipment must be inspected at least once every three years; at a minimum, the inspection must ensure that overfill prevention equipment is set to activate at the correct level specified in 18 AAC 78.025(g) and will activate when petroleum reaches that level; inspections must be conducted in accordance with one of the criteria in (1)(B)(i) - (iii) of this subsection; and

(3) to meet the requirements of (1)(B) and (2) of this subsection, an owner or operator shall ensure that one of the following is used:

(A) Petroleum Equipment Institute Recommended Practice RP1200-12, Recommended Practices for the Testing and Verification of Spill, Overfill, Leak Detection and Secondary Containment Equipment at UST Facilities, 2012, adopted by reference; or

(B) another procedure, code, or standard that is no less protective of human health and safety and the environment and approved by the department.

(b) The owner or operator shall begin meeting the requirements of (a) of this section as follows:

(1) for USTs in use on or before October 13, 2015, the initial spill prevention equipment test, containment sump test, and overfill prevention equipment inspection must be conducted not later than October 13, 2018; and

(2) for USTs brought into use after October 13, 2015, these requirements apply at installation.

(c) The owner or operator shall maintain records as follows, in accordance with 18 AAC 78.056, for spill prevention equipment, containment sumps used for interstitial monitoring of piping, and overfill prevention equipment:

(1) all records of testing or inspection must be maintained for three years; and

(2) for spill prevention equipment and containment sumps used for interstitial monitoring of piping not tested every three years, documentation showing that the prevention equipment is double walled and the integrity of both walls is periodically monitored must be maintained for as long as the equipment is periodically monitored.
