Section 45-21-46 - Test Methods and Compliance Procedures: Leak Detection Methods for Volatile Organic Compounds (VOCs)
46.1. Owners or operators required to carry out a leak detection monitoring program shall comply with the following requirements:
46.1.1. Monitoring shall be performed in accordance with Method 21 of 40 CFR Part 60, Appendix A.
46.1.2. The detection instrument shall meet the performance criteria of Method 21.
46.1.3. The detection instrument shall be calibrated before and after use on each day of its use by the methods specified in Method 21. Failure to achieve a post-use calibration precision of 10 percent or less shall constitute grounds for rejecting all tests performed since the last pre-use calibration. In such cases, required leak tests shall be reperformed.
46.1.4. Calibration gases shall be:
46.1.4.a. Zero air (less than 10 parts per million [ppm] of hydrocarbon in air); and
46.1.4.b. A mixture of methane or n-hexane and air at a concentration of approximately, but less than, 10,000 ppm methane or n-hexane.
46.1.5. The detection instrument probe shall be traversed around all potential leak interfaces as close to the interface as possible as described in Method 21.
46.2. When equipment is tested for compliance with the requirement that there be no detectable emissions, the test shall comply with the following:
46.2.1. The requirements of subdivisions 46.1.1. through 46.1.5. shall apply and shall be met; and
46.2.2. The background level shall be determined as set forth in Method 21.
46.3. Leak detection tests shall be performed consistent with:
46.3.1. "APTI Course SI 417-Controlling Volatile Organic Compound Emissions from Leaking Process Equipment," EPA-450/2-82-015;
46.3.2. "Portable Instrument User's Manual for Monitoring VOC Sources," EPA-340/1-86-015;
46.3.3. "Protocols for Generating Unit-Specific Emission Estimates for Equipment Leaks of VOC and VHcAP," EPA-450/3-88-010; and
46.3.4. "Petroleum Refinery Enforcement Manual," EPA-340/1-80-008.
46.4. Use of adaptations to test methods. -- Use of an adaptation to any of the analytical methods specified in subsections 46.1., 46.2., and 46.3. may be approved by the Secretary and the U.S. EPA on a case-by-case basis. An owner or operator shall submit sufficient documentation for the Secretary and the U.S. EPA to find that the analytical methods specified in subsections 46.1., 46.2., and 46.3. will yield inaccurate results and that the proposed adaptation is appropriate.
