Current through Register Vol. 24-14, July 15, 2024
(1) The owner or operator of a MSW landfill,
			 or a third-party owner or operator, must maintain records as prescribed in this
			 subsection. The records must be provided by the owner or operator to the
			 department or local authority within five business days of a request. Records
			 described in this subsection must be retained in the operating record required
			 by WAC 173-351-200
			 (10)(a).
(a) An owner or operator must maintain the
			 following records for at least five years:
(i)
			 All surface emission monitoring plans and monitoring records.
(ii) All records of gas collection system
			 downtime exceeding five calendar days, including individual well shutdown and
			 disconnection times, and the reason for the downtime.
(iii) All records of 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.
(iv) Expected gas generation flow rate
			 calculated in accordance with WAC 173-408-120(5).
(v) Records of all instantaneous surface
			 readings of 200 ppmv or greater, in accordance with WAC 173-408-120
			 (3)(b)(i).
(vi) All exceedances of
			 the limits set forth in WAC 173-408-100(2), including the location of the leak
			 (or affected grid), leak concentration in ppmv, date and time of measurement,
			 the action(s) taken to repair the leak, date of repair, any required
			 remonitoring and the remonitored concentration in ppmv, wind speed and
			 barometric pressure during surface sampling; and the installation date and
			 location of each well installed as part of a gas collection system
			 expansion.
(vii) Records of any
			 component leak exceedances and corrective actions taken, in accordance with WAC
			 173-408-110 (2)(c).
(viii) Records
			 of any positive wellhead gauge pressure measurements, the date of the
			 measurements, the well identification number, and the corrective action taken,
			 in accordance with WAC 173-408-110(3).
(ix) Annual solid waste acceptance rate and
			 the current amount of waste in place.
(x) Records of the nature, location, amount,
			 and date of deposition of nondecomposable waste for any landfill areas excluded
			 from the collection system.
(xi)
			 Results of any source tests conducted pursuant to WAC 173-408-120(6).
(xii) Records describing the mitigation
			 measures taken to prevent the release of methane or other emissions into the
			 ambient air:
(A) When solid waste was brought
			 to the surface during the installation or preparation of wells, piping, or
			 other equipment;
(B) During repairs
			 or the temporary shutdown of gas collection system components; or
(C) When solid waste was excavated and
			 moved.
(xiii) Records of
			 the equipment operating parameters specified to be monitored under WAC
			 173-408-110 (2)(a) and (b), 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:
(A) For enclosed flares, all three-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 WAC
			 173-408-080 (4) and (5)    was determined.
(B) 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 WAC 173-408-080 (5)(a)(ii).
(C) 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 WAC 173-408-080(5), 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, or local regulatory
			 requirements).
(xiv)
			 Records of any actions involving disturbance or removal of areas of the
			 landfill surface where the landfill cover material has been removed for the
			 purpose of installing, expanding, replacing, or repairing components of the
			 landfill cover system, the landfill gas collection and control system, the
			 leachate collection and removal system, or a landfill gas condensate collection
			 and removal system. The records must contain the following information:
(A) 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.
(B) Disturbance or removal start and finish
			 dates, projected equipment installation dates, and projected shut down times
			 for individual gas collection system components.
(C) A description of the mitigation measures
			 taken to minimize methane emissions and other potential air quality
			 impacts.
(xv) Records of
			 any active mining activities, as defined in WAC 173-408-020. The records must
			 contain the following information:
(A) 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.
(B) Active mining start
			 and finish dates and projected shut down times for individual gas collection
			 system components.
(C) A
			 description of the mitigation measures taken to minimize methane emissions and
			 other potential air quality impacts.
(xvi) Records of any law enforcement
			 activities requiring excavation. The records must contain the following
			 information:
(A) 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.
(B) Law enforcement activity start and finish
			 dates and projected shut down times for individual gas collection system
			 components.
(C) A description of
			 the mitigation measures taken to minimize methane emissions and other potential
			 air quality impacts.
