Current through Register Vol. 48, No. 28, July 12, 2024
a) Owners or operators of new and existing
				USTs shall provide a method, or combination of methods, of release detection
				that:
1) Can detect a release from the entire
				tank and any portion of 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;
3) Meets the
				performance requirements in Sections
				175.630,
				175.640 or Subpart I, as
				applicable. All performance claims and the manner of determining the claims
				shall be described in writing by the equipment manufacturer or installer. In
				addition, methods used shall be capable of detecting the leak rate or quantity
				specified for that method in Section
				175.630 and
				175.640 with a probability of
				detection of 0.95 and a probability of false
				alarm of 0.05. Release detection for
				tanks and piping permitted on or after February 1, 2008 must also meet the
				interstitial monitoring requirements indicated in Sections
				175.400 and
				175.420; and
4) Beginning October 13, 2018, is operated
				and maintained, and electronic and mechanical components are tested for proper
				operation, in accordance with manufacturer's instructions or a code of practice
				developed by a nationally recognized association or independent testing
				laboratory. As an alternative, another test method may be used that is
				determined by OSFM to be not less protective of human health and the
				environment. Before the utilization of any such method, it shall be submitted
				to OSFM in writing, and OSFM shall issue written approval.
A) A test of the proper operation must be
				performed at installation and at least annually thereafter and, at a minimum,
				as applicable to the facility, shall 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
				175.640(a)(3)
				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.
B) All testing and inspections required by
				this Section shall be performed:
i) By an
				OSFM-licensed contractor that has licensure in the installation/retrofitting or
				inspection and testing of UST equipment module; and
ii) Using an employee of the OSFM-licensed
				contractor for testing or inspection who is certified in the
				installation-retrofitting or inspection and testing of UST equipment
				module.
