Section 340-230-0340 - Municipal Waste Combustors: Monitoring and Testing

(1) The standards under OAR 340-230-0300 through 0359 apply at all times except during periods of startup, shutdown, and malfunction. Duration of startup, shutdown, or malfunction periods are limited to 3 hours per occurrence, except as provided in subsection (1)(c) of this rule. During periods of startup, shutdown, or malfunction, monitoring data must be dismissed or excluded from compliance calculations, but must be recorded and reported in accordance with the provisions of OAR 340-230-0350(1)(f).

(a) The startup period commences when the affected facility begins the continuous burning of municipal solid waste and does not include any warmup period when the affected facility is combusting fossil fuel or other non municipal solid waste fuel, and no municipal solid waste is being fed to the combustor.

(b) Continuous burning is the continuous, semicontinuous, or batch feeding of municipal solid waste for purposes of waste disposal, energy production, or providing heat to the combustion system in preparation for waste disposal or energy production. The use of municipal solid waste solely to provide thermal protection of the grate or hearth during the startup period when municipal solid waste is not being fed to the grate is not considered to be continuous burning.

(c) For purposes of compliance with the carbon monoxide emissions limit in OAR 340-230-320(1), if a loss of boiler water level control (e.g., boiler waterwall tube failure) or a loss of combustion air control (e.g., loss of combustion air fan, induced draft fan, combustion grate bar failure) is determined to be a malfunction, the duration of the malfunction period is limited to 15 hours per occurrence. During such periods of malfunction, monitoring data must be dismissed or excluded from compliance calculations, but must be recorded and reported in accordance with the provisions of OAR 340-230-0350(1)(f).

(2) The owner or operator of an affected facility must install, calibrate, maintain, and operate a continuous emission monitoring system for measuring the oxygen or carbon dioxide content of the flue gas at each location where carbon monoxide, sulfur dioxide, or nitrogen oxides emissions, or particulate matter (if the owner or operator elects to continuously monitor emissions under section (13) of this rule) are monitored and record the output of the system and must comply with the test procedures and test methods specified in subsections (2)(a) through (g) of this rule.

(b) For batch feed municipal waste combustor units, municipal waste combustor unit capacity must be calculated as the maximum design amount of municipal solid waste that can be charged per batch multiplied by the maximum number of batches that could be processed in a 24-hour period. The maximum number of batches that could be processed in a 24-hour period is calculated as 24 hours divided by the design number of hours required to process one batch of municipal solid waste, and may include fractional batches (e.g., if one batch requires 16 hours, then 24/16, or 1.5 batches, could be combusted in a 24-hour period). For batch combustors that are designed based on heat capacity, the design heating value of 12,800 kilojoules per kilogram for combustors firing refuse-derived fuel and a heating value of 10,500 kilojoules per kilogram for combustors firing municipal solid waste that is not refuse-derived fuel must be used in calculating the municipal waste combustor unit capacity in megagrams per day of municipal solid waste.

Data quality objectives are the pre-evaluation expectations of precision, accuracy, and completeness of data. The internal quality assurance program must include, at a minimum, the activities planned by routine operators and analysts to provide an assessment of continuous automated sampling system performance, for example, plans for relative accuracy testing using the appropriate reference method in subsection (15)(c) of this rule, and an assessment of quality of analysis results. The external quality assurance program must include, at a minimum, systems audits that include the opportunity for on-site evaluation by the Administrator or the Department of instrument calibration, data validation, sample logging, and documentation of quality control data and field maintenance activities.

(f) Conduct a performance evaluation of each continuous automated sampling system in accordance with the site-specific monitoring plan.

(g) Operate and maintain the continuous automated sampling system in continuous operation according to the site-specific monitoring plan.

(17) Continuous monitoring for opacity, sulfur dioxide, nitrogen oxides, carbon monoxide, and diluent gases (oxygen or carbon dioxide) must be conducted in accordance with the Department's Continuous Monitoring Manual and the specific requirements of this rule. If at any time there is a conflict between the Department's Continuous Monitoring Manual and the federal requirements contained in 40 CFR 60.13, Appendix B and Appendix F), the federal requirements must govern.
