(a)
Recordkeeping
						Requirements.
(1) An owner or
						operator must maintain the following records, whether in paper, electronic, or
						other format, for at least five years:
(A) All
						gas collection system downtime exceeding five calendar days, including
						individual well shutdown and disconnection times, and the reason for the
						downtime.
(B) All gas control
						system downtime in excess of one hour, the reason for the downtime, and the
						length of time the gas control system was shutdown.
(C) Expected gas generation flow rate
						calculated pursuant to section
						95471(e).
(D) Records of all instantaneous surface
						readings of 200 ppmv or greater; all exceedances of the limits in sections
						95464(b)(1)(B) or
						95465, including the location of
						the leak (or affected grid), leak concentration in ppmv, date and time of
						measurement, the action taken to repair the leak, date of repair, any required
						re-monitoring and the re-monitored concentration in ppmv, and wind speed during
						surface sampling; and the installation date and location of each well installed
						as part of a gas collection system expansion.
(E) Records of any positive wellhead gauge
						pressure measurements, the date of the measurements, the well identification
						number, and the corrective action taken.
(F) Annual solid waste acceptance rate and
						the current amount of waste-in-place.
(G) Records of the nature, location, amount,
						and date of deposition of non-degradable waste for any landfill areas excluded
						from the collection system.
(H)
						Results of any source tests conducted pursuant to section
						95464(b)(4).
(I) Records describing the mitigation
						measures taken to prevent the release of methane or other emissions into the
						atmosphere:
1. When solid waste was brought to
						the surface during the installation or preparation of wells, piping, or other
						equipment;
2. During repairs or the
						temporary shutdown of gas collection system components; or,
3. When solid waste was excavated and
						moved.
(J) Records of any
						construction activities pursuant to section
						95466. The records must contain
						the following information:
1. A description of
						the actions being taken, the areas of the MSW landfill that will be affected by
						these actions, the reason the actions are required, and any landfill gas
						collection system components that will be affected by these actions.
2. Construction start and finish dates,
						projected equipment installation dates, and projected shut down times for
						individual gas collection system components.
3. A description of the mitigation measures
						taken to minimize methane emissions and other potential air quality
						impacts.
(K) Records of
						the equipment operating parameters specified to be monitored under sections
						95469(b)(1) and
						95469(b)(2) as
						well as records for periods of operation during which the parameter boundaries
						established during the most recent source test are exceeded. The records must
						include the following information:
1. For
						enclosed flares, all 3-hour periods of operation during which the average
						temperature difference was more than 28 degrees Celsius (or 50 degrees
						Fahrenheit) below the average combustion temperature during the most recent
						source test at which compliance with sections
						95464(b)(2) and
						95464(b)(3)(A)
						was determined.
2. For boilers or
						process heaters, whenever there is a change in the location at which the vent
						stream is introduced into the flame zone pursuant to section
						95464(b)(3)(A)2.
3. For any owner or operator who uses a
						boiler or process heater with a design heat input capacity of 44 megawatts (150
						MMBtu/hr) or greater to comply with section
						95464(b)(3), all
						periods of operation of the boiler or process heater (e.g., steam use, fuel
						use, or monitoring data collected pursuant to other federal, State, local, or
						tribal regulatory requirements).
