Current through Register Vol. 48, No. 6, June 28, 2024
(a) Owners and operators of UST systems must
				  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
				  product;
(2) Is installed,
				  calibrated, operated, and maintained in accordance with the manufacturer's
				  instructions, including routine maintenance and service checks for operability
				  or running condition; and
(3)
				  Beginning on May 26, 2020, is operated and maintained, and electronic and
				  mechanical components are tested for proper operation, in accordance with one
				  of the following: manufacturer's instructions; a code of practice developed by
				  a nationally recognized association or independent testing laboratory; or
				  requirements determined by the Department to be no less protective of human
				  health and the environment than the two options listed in paragraphs (a)(1) and
				  (2) of this section. A test of the proper operation must be performed at least
				  annually, documented on a Department form, a Department approved form, or
				  submitted in a format as approved by the Department and, at a minimum, as
				  applicable to the facility, cover the following components and criteria:
(i) Automatic tank gauge and other
				  controllers: test alarm; verify system configuration; test battery
				  backup;
(ii) Probes and sensors:
				  inspect for residual buildup; ensure floats move freely; ensure shaft is not
				  damaged; ensure cables are free of kinks and breaks; test alarm operability and
				  communication with controller;
(iii) Automatic line leak detector: test
				  operation to meet criteria in Section 280.44(a) by simulating a leak;
(iv) Vacuum pumps and pressure gauges: ensure
				  proper communication with sensors and controller; and
(v) Hand-held electronic sampling equipment
				  associated with groundwater and vapor monitoring: ensure proper operation.
[Note to paragraph (a)(3).The following code of practice
					 may be used to comply with paragraph (a)(3) of this section: Petroleum
					 Equipment Institute Publication RP1200, "Recommended Practices for the Testing
					 and Verification of Spill, Overfill, Leak Detection and Secondary Containment
					 Equipment at UST Facilities."]
(4) Meets the performance requirements in
				  Sections 280.43, 280.44, or subpart K of this part, as applicable, with any
				  performance claims and their manner of determination described in writing by
				  the equipment manufacturer or installer. In addition, the methods listed in
				  Section 280.43(b), (c), (d), (h), and (i), Section 280.44(a), (b), and subpart
				  K of this part, must be capable of detecting the leak rate or quantity
				  specified for that method in the corresponding section of the rule with a
				  probability of detection of 0.95 and a probability of false alarm of
				  0.05.
