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

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

(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
