(1) Applicable sources shall comply with the following:
(a) The owner or operator shall
develop an emissions monitoring plan that shall be available upon request to
review for each individual well site. At a minimum, the plan shall include:
(i) monitoring frequency;
(ii) monitoring technique and
equipment;
(iii) procedures and
timeframes for identifying and repairing leaks;
(iv) recordkeeping practices; and
(v) calibration and maintenance procedures
for monitoring equipment.
(b) The plan shall address monitoring for
difficult-to-monitor and unsafe-to-monitor components.
(c) The owner or operator shall conduct
monitoring surveys on site to observe each fugitive emissions component for
fugitive emissions.
(d) Monitoring
surveys shall be conducted according to the following schedule:
(i) No later than 60 days after startup of
production, as defined in 40 CFR 60 Subpart OOOOa Standards of Performance for
Crude Oil and Natural Gas Production, Transmission and Distribution.
(ii) Semiannually after the initial
monitoring survey. Consecutive semiannual monitoring surveys shall be conducted
at least four months apart and no more than seven months apart.
(iii) Annually after the initial monitoring
survey for "difficult-to-monitor" components.
(iv) As required by the owner or operator's
monitoring plan for "unsafe-to-monitor" components.
(e) Monitoring surveys shall be conducted
using one or both of the following to detect fugitive emissions:
(i) Optical gas imaging (OGI) equipment. OGI
equipment shall be capable of imaging gases in the spectral range for the
compound of highest concentration in the potential fugitive emissions
source.
(ii) Monitoring equipment
that meets U.S. EPA Method 21, 40 CFR Part 60, Appendix A.
(f) If fugitive emissions are detected at any
time, the owner or operator shall repair the fugitive emissions component as
soon as possible but no later than 15 calendar days after detection. If the
repair or replacement is technically infeasible, would require a vent blowdown,
a well shutdown or well shut-in, or would be unsafe to repair during operation
of the unit, the repair or replacement shall be completed during the next well
shutdown, well shut-in, after an unscheduled, planned, or emergency vent
blowdown or within 24 months, whichever is earlier.
(g) The owner or operator shall resurvey the
repaired or replaced fugitive emission component no later than 30 calendar days
after the fugitive emission component was repaired.
