Section 130. General requirements for all petroleum and hazardous substance UST systems

Part IV. Release Detection

A. Owners and operators of new and existing 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. Meets the performance requirements in 9VAC25-580-160 or 9VAC25-580-170, with any performance claims and their manner of determination described in writing by the equipment manufacturer or installer. In addition, methods used after December 22, 1990, except for methods permanently installed prior to that date, must be capable of detecting the leak rate or quantity specified for that method in subdivisions 2, 3, and 4 of 9VAC25-580-160 or subdivisions 1 and 2 of 9VAC25-580-170 with a probability of detection of 0.95 and a probability of false alarm of 0.05.

B. When a release detection method operated in accordance with the performance standards in 9VAC25-580-160 or 9VAC25-580-170 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.
