Virginia Administrative Code › Title 9 - ENVIRONMENT › Agency 25 - STATE WATER CONTROL BOARD › Chapter 580 - UNDERGROUND STORAGE TANKS: TECHNICAL STANDARDS AND CORRECTIVE ACTION REQUIREMENTS › Part IV - Release Detection › Section 9VAC25-580-130 - General requirements for all petroleum and hazardous substance UST systems

Current through Register Vol. 40, No. 24, July 15, 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 and calibrated in accordance with the manufacturer's instructions,
				  including routine maintenance and service checks for operability or running
				  condition;
3. Beginning on January
				  1, 2021, is operated and maintained, and electronic and mechanical components
				  are tested for proper operation, in accordance with one of the following:
(i) manufacturer's instructions;
(ii) a code of practice developed by a
				  nationally recognized association or independent testing laboratory; or
(iii) requirements determined by
				  the department to be no less protective of human health and the environment
				  than the two options listed in subdivisions 1 and 2 of this subsection. A test
				  of the proper operation must be performed at least annually and, at a minimum,
				  as applicable to the facility, cover the following components and criteria:
a. Automatic tank gauge and other
				  controllers: test alarm; verify system configuration; test battery
				  backup;
b. 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;
c.
				  Automatic line leak detector: test operation to meet criteria in subdivision 1
				  of
				  9VAC25-580-170
				  by simulating a leak;
d. Vacuum
				  pumps and pressure gauges: ensure proper communication with sensors and
				  controller; and
e. Handheld
				  electronic sampling equipment associated with groundwater and vapor monitoring:
				  ensure proper operation.
NOTE: The following code of practice may be used to comply
					 with subdivision 3 of this subsection. Petroleum Equipment Institute
					 Publication RP 1200, 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
				  9VAC25-580-160
				  or
				  9VAC25-580-170
				  or Part X (9VAC25-580-380
				  et seq.) of this chapter 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 subdivisions 2, 3, 4, 8, and 9 of
				  9VAC25-580-160;
				  subdivisions 1 and 2 of
				  9VAC25-580-170;
				  and Part X must be capable of detecting the leak rate or quantity specified for
				  that method in the corresponding section of the regulation with a probability
				  of detection of 0.95 and a probability of false alarm of 0.05.
