R315-265-1061. Air Emission Standards for Equipment Leaks -- Alternative Standards for Valves in Gas or Vapor Service or in Light Liquid Service: Percentage of Valves Allowed to Leak

(a) An owner or operator subject to the requirements of Section R315-265-1057 may elect to have the valves within a hazardous waste management unit comply with an alternative standard that allows no greater than 2% 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% of valves to leak: (1) A performance test as specified in Subsection R315-265-1061(c) shall be conducted initially upon designation, annually, and at other times requested by the director. (2) If a valve leak is detected, it shall be repaired in accordance with Subsections R315-265-1057(d) and R315-265-1057(e). (c) Performance tests shall be conducted in the following manner: (1) Valves subject to the requirements in Section R315-265-1057 within the hazardous waste management unit shall be monitored within 1 week by the methods specified in Subsection R315-265-1063(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 Section R315-265-1057 that have detected leaks by the total number of valves subject to the requirements in Section R315-265-1057 within the hazardous waste management unit.
