Part IV
Release Detection

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 board 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.

B. When a release detection method operated in accordance with the performance standards in 9VAC25-580-160, 9VAC25-580-170, or Part X of this chapter indicates a release may have occurred, owners and operators must notify the board in accordance with Part V (9VAC25-580-190 et seq.) of this chapter.

C. Any UST system that cannot apply a method of release detection that complies with the requirements of this part must complete the closure procedures in Part VII (9VAC25-580-310 et seq.) of this chapter. For previously deferred UST systems described in Parts I (9VAC25-580-10 et seq.) and X of this chapter, this requirement applies on or after the effective dates described in 9VAC25-580-20 A 1 b and c and 9VAC25-580-380 A 1.
