| (I) For leaks detected over 10,000 ppmv, extraordinary efforts must be undertaken within 14 calendar days after the leak is found. The owner or operator may keep the leaking valve on the shutdown list only after two unsuccessful attempts to repair a leaking valve through extraordinary efforts, provided that the second extraordinary effort attempt is made within 15 days of the first extraordinary effort attempt. (II) For all other leaks, extraordinary efforts must be undertaken within 30 calendar days after the leak is found, and a second extraordinary effort attempt is not required to keep the valve on the shutdown list. (III) For any leak detected from a component using the alternative work practice in §115.358 of this title, extraordinary efforts must be performed as specified in subclause (I) of this clause. If the owner or operator measures the leak concentration using Method 21 and demonstrates the leak concentration is 10,000 ppmv or less, then extraordinary efforts must be as specified in subclause (II) of this clause. The Method 21 test must be performed no later than one business day after the leak was detected using the alternative work practice screening. (ii) The owner or operator maintains, and makes available upon request, documentation to authorized representatives of EPA, the executive director, and any local air pollution control agency having jurisdiction that demonstrates that there is a safety, mechanical, or major environmental concern posed by repairing the leak by using extraordinary efforts and emissions from the leaking valves are included in the calculation of total daily mass emissions required by paragraph (1)(B)(i)(IV) of this subsection. (B) The valve is isolated from the process and does not remain in HRVOC service. (d) Demonstration of repair. For the purposes of this section, a component is considered repaired: (1) for any component that the owner or operator monitors using the alternative work practice in §115.358 of this title, when the component is demonstrated to no longer have a leak after adjustments or alterations to the component by either screening using an optical gas imaging instrument as specified in §115.358 of this title or by using Method 21 at the leak definition in §115.781(b)(9) of this title (relating to General Monitoring and Inspection Requirements); and (2) for all other components, when the component is demonstrated to no longer have a leak after adjustments or alterations to the component by the normal monitoring method required under this division. |
