A. An owner or operator subject to the requirements of LAC 33:V.1729 may elect to have all valves within a hazardous waste management unit comply with an alternative standard that allows no greater than 2 percent of the valves to leak. B. The following requirements shall be met if an owner or operator decides to comply with the alternative standard of allowing 2 percent of the valves to leak. 1. A performance test as specified in Subsection C of this Section shall be conducted initially upon designation, annually, and at other times requested by the administrative authority. 2. If a valve leak is detected, it shall be repaired in accordance with LAC 33:V.1729.D and E. C. Performance tests shall be conducted in the following manner. 1. All valves subject to the requirements of LAC 33:V.1729 within the hazardous waste management unit shall be monitored within one week by the methods specified in LAC 33:V.1741.B. 2. If an instrument reading of 10,000 ppm or greater is measured, a leak is detected. 3. The leak percentage shall be determined by dividing the number of valves subject to the requirements in LAC 33:V.1729 for which leaks are detected by the total number of valves subject to the requirements in LAC 33:V.1729 within the hazardous waste management unit.
