Except as provided in subdivision 74:36:07:126(2), the owner or operator of a control system at an existing municipal solid waste landfill shall maintain the control device vendor specifications and the following records, readily accessible, for the life of the control system equipment as measured during the initial performance test or compliance determination. The following records of subsequent tests or monitoring shall be maintained for a minimum of five years:
(1) Where an owner or operator seeks to demonstrate compliance with § 74:36:07:106: (a) The maximum expected gas generation flow rate as calculated in subdivision 74:36:07:112(1). The owner or operator may use another method to determine the maximum gas generation flow rate, if the method has been approved by the Secretary; and(b) The density of wells, horizontal collectors, surface collectors, or other gas extraction devices determined using the procedures specified in subdivision 74:36:07:131(1)(a);(2) Where an owner or operator seeks to demonstrate compliance with § 74:36:07:109 through use of an enclosed combustion device other than a boiler or process heater with a design heat input capacity equal to or greater than 44 megawatts: (a) The average temperature measured at least every 15 minutes and averaged over the same time period of the performance test; and(b) The percent reduction of nonmethane organic compounds achieved by the control device;(3) Where an owner or operator seeks to demonstrate compliance with § 74:36:07:107 through use of a boiler or process heater of any size, a description of the location at which the collected gas vent stream is introduced into the boiler or process heater over the same time period of the performance test;(4) Where an owner or operator seeks to demonstrate compliance with subdivision 74:36:07:109(1) through use of a non-enclosed flare, the flare type, all visible emission readings, heat content determination, flow rate or bypass flow rate measurements, and exit velocity determinations made during the performance test; and continuous records of the flare pilot flame or flare flame monitoring and records of all periods of operations during which the pilot flame or the flare flame is absent;(5) Where an owner or operator seeks to demonstrate compliance with subdivision 74:36:07:107(4) through use of a landfill gas treatment system:(a) Records of the flow of landfill gas to, and bypass of, the treatment system; and(b) Develop and maintain a site-specific treatment monitoring plan, to include:(i) Monitoring records of parameters identified in the treatment system monitoring plan and ensure the treatment system is operating properly for each intended end use of the treated landfill gas. At a minimum, records should include records of filtration, de-watering, and compression parameters that ensure the treatment system is operating properly for each intended end use of the treated landfill gas;(ii) Monitoring methods, frequencies, and operating ranges for each monitored operating parameter based on manufacturer's recommendations or engineering analysis for each intended end use of the treated landfill gas;(iii) Documentation of the monitoring methods and ranges, along with justification for their use;(iv) Identify who is responsible, by job title, for data collection;(v) Processes and methods used to collect the necessary data; and(vi) Description of the procedures and methods that are used for quality assurance, maintenance, and repair of all continuous monitoring systems.S.D.
