12. Notwithstanding paragraph 2, operators shall survey components that were found to be emitting:
|
(a)
|
at levels of methane equal to or higher than the thresholds set out in paragraph 8 at standard temperature and pressure during a previous LDAR survey, immediately after the repair carried out pursuant to paragraph 9 and no later than 45 days thereafter, to ensure that the repair was successful; and
|
|
(b)
|
at levels of methane lower than the thresholds set out in paragraph 8 at standard temperature and pressure, no later than 3 months from the date on which the emissions were detected, to check at least once whether the size of methane loss has changed and whether a repair is necessary.
|
Where a higher safety risk or a higher risk of methane leaks is identified, the competent authorities may recommend that LDAR surveys of the relevant components take place more frequently.
