Leak Detection and Equipment Leaks
Changed
Last updated: 8 months ago
- Q601. What types of equipment meet the requirements of Method 21 in §98.234(a)(2)? Does the rule provide an avenue to use devices excluded by the performance specifications that can accurately measure the 10,000 ppm-leak threshold?
- Q602. What documentation is required for leak surveys?
- Q603. Can a facility choose between (a) the provided emission factors or (b) conducting a statistical analysis and calculating a site-specific emission factor and applying it "across the board" to that facility and to other facilities with like equipment?
- Q604. Does the Hi Flow Sampler qualifies as a meter?
- Q605. Can data from a state permit-required fugitive emissions monitoring program already in place, which has a lower leak detection rate of 500 ppm, be used to estimate fugitive greenhouse gas emissions under 40 CFR 98.233(q)?
- Q606. Does 40 CFR 98.233(q), "Leak detection and leaker emission factors," apply to wellheads, separators at well site, storage tanks and other equipment defined by "production equipment"?
- Q607. A Method 21 leak is a reading equal to or greater than 10,000 ppm. Does this include methane?
- Q608. Can leak repair logs be used to determine leak duration?
- Q609. Under 98.234(a) are there circumstances, or component classes, for which use of instruments other than an optical gas imaging instrument and elevation of personnel is acceptable?
- Q610. For which source categories does the rule require the reporting of equipment leaks calculated using population count and factors per §98.233(r)?
