Current through May 31, 2024
(a) The owner or
				operator of a UST shall provide a method, or combination of methods, of release
				detection that
(1) can detect a release from
				any portion of the tank and the connected underground piping that routinely
				contains petroleum;
(2) is
				installed and calibrated in accordance with the manufacturer's
				instructions;
(3) meets the
				performance requirements in 18 AAC 78.065,
				18 AAC 78.070, or 18 AAC 78.705,
				with any performance claims and the manner of determination described in
				writing by the equipment manufacturer or installer;
(4) is capable of detecting a leak as
				specified in
				18 AAC 78.065(c), (d), (e), (i), or (j),
				18 AAC 78.070(b), (c), or (d), or 18 AAC 78.705 with a probability of
				detection of 95 percent and a probability of false alarm of five percent;
				and
(5) is operated and maintained,
				and electronic and mechanical components are tested for proper operation, in
				accordance with the manufacturer's instructions, a nationally recognized code
				of practice, or requirements determined by the department to be no less
				protective of human health and the environment than the requirements listed in
				(1) and (2) of this subsection: as follows, the owner or operator shall perform
				a test of the proper operation at least annually and, at a minimum, as
				applicable to the facility, shall cover the following components and criteria:
(A) the owner or operator shall test the
				automatic tank gauge and other controllers, including a test of the alarm,
				verification of system configuration, and a test of the battery
				backup:
(B) the owner or operator
				shall test the probes and sensors, including an inspection for residual
				buildup, shall ensure that floats move freely, shall ensure that the shaft is
				not damaged, shall ensure that cables are free of kinks and breaks, shall test
				alarm operability and communication with the controller, and shall remove
				probes from the tank to be properly inspected;
(C) the owner or operator shall test the
				operation of the automatic line leak detector to meet criteria in
				18 AAC 78.070(b)
				by simulating a leak;
(D) the owner
				or operator shall test vacuum pumps and pressure gauges to ensure proper
				communication with sensors and the controller;
(E) the owner or operator shall test
				hand-held electronic sampling equipment associated with groundwater and vapor
				monitoring to ensure proper operation; and
(F) to meet the requirements of this
				paragraph, an owner or operator shall ensure that one of the following is used:
(i) Petroleum Equipment Institute Publication
				RP1200-12, Recommended Practices (or the Testing and Verification of Spill.
				Overfill, Leak Detection and Secondary Containment Equipment at UST Facilities,
				2012, adopted by reference; or
(ii)
				another procedure, code, or standard that is no less protective of human health
				and safety and the environment and approved by the department.
