§265.1061. Alternative standards for valves in gas/vapor service or in light liquid service: percentage of valves allowed to leak.
40 C.F.R. § 265.1061
An owner or operator subject to the requirements of § 265.1057 may elect to have all valves within a hazardous waste management unit comply with an alternative standard which allows no greater than 2 percent of the valves to leak.
The following requirements shall be met if an owner or operator decides to comply with the alternative standard of allowing 2 percent of valves to leak:
A performance test as specified in paragraph (c) of this section shall be conducted initially upon designation, annually, and at other times requested by the Regional Administrator.
If a valve leak is detected, it shall be repaired in accordance with § 265.1057 (d) and (e).
Performance tests shall be conducted in the following manner:
All valves subject to the requirements in § 265.1057 within the hazardous waste management unit shall be monitored within 1 week by the methods specified in § 265.1063(b).
If an instrument reading of 10,000 ppm or greater is measured, a leak is detected.
The leak percentage shall be determined by dividing the number of valves subject to the requirements in § 265.1057 for which leaks are detected by the total number of valves subject to the requirements in § 265.1057 within the hazardous waste management unit.
