OAR 340-240-0210: Medford-Ashland Air Quality Maintenance Area and Grants Pass Urban Growth Area: Continuous Monitoring

(1) DEQ will require the installation and operation of instrumentation for measuring and recording emissions and/or the parameters which affect the emission of air contaminants from wood-waste fired boilers, veneer dryers, fiber dryers, and particle dryers to ensure that the sources and the air pollution control devices are operated at all times at their full efficiency and effectiveness so that the emission of air contaminants is kept at the lowest practicable level. The instrumentation must be periodically calibrated. The method and frequency of calibration must be approved in writing by DEQ. Continuous monitoring equipment and operation must be in accordance with the DEQ Continuous Monitoring Manual. [NOTE: The DEQ Continuous Monitoring Manual is published with OAR 340-200-0035.] The recorded information must be kept for a period of at least one year and must be made available to DEQ upon request. (2) At a minimum, the monitoring required under paragraph (1) must include: (a) Continuous monitoring and monthly reporting of carbon monoxide concentration and oxygen concentration for any wood-waste fired boiler with a heat input capacity greater than 35 million BTU/hr or for any wood-waste boiler using a wet scrubber as pollution control device and steam production rate for any wood-waste fired boiler; (b) Continuous monitoring and monthly reporting of pressure drop, scrubber water pressure, and scrubber water flow or other parameters deemed by DEQ to be equal or better indicators of proper operation of the wet scrubber used as pollution control device for any wood-waste fired boiler, veneer dryer, particle dryer, or fiber dryer; and (c) Continuous monitoring and monthly reporting of opacity for any wood-waste fired boiler not controlled by a wet scrubber. [NOTE: This rule is included in the State of Oregon Clean Air Act Implementation Plan that EQC adopted under OAR 340-200-0040.]
