OAR 340-212-0220: Compliance Assurance Monitoring: Submittal Requirements

(1) The owner or operator must submit to DEQ monitoring plans that satisfy the design requirements in OAR 340-212-0210. The submission must include the following information: (a) The indicators to be monitored to satisfy OAR 340-212-0210(1)(a) and (b); (b) The ranges or designated conditions for such indicators, or the process by which such indicator ranges or designated conditions will be established; (c) The performance criteria for the monitoring to satisfy OAR 340-212-0210(2); and (d) If applicable, the indicator ranges and performance criteria for a CEMS, COMS or PEMS pursuant to OAR 340-212-0210(4). (2) As part of the information submitted, the owner or operator must submit a justification for the proposed elements of the monitoring plans. If the performance specifications proposed to satisfy OAR 340-212-0210(2)(b) or (c) include differences from manufacturer recommendations, the owner or operator must explain the reasons for the differences. The owner or operator also must submit any data supporting the justification and may refer to generally available sources of information used to support the justification, such as generally available air pollution engineering manuals, or EPA or DEQ publications on appropriate monitoring for various types of control devices or capture systems. To justify the appropriateness of the monitoring elements proposed, the owner or operator may rely in part on existing applicable requirements that establish the monitoring for the applicable regulated pollutant-specific emissions unit or a similar unit. If an owner or operator relies on presumptively acceptable monitoring, no further justification for the appropriateness of that monitoring should be necessary other than an explanation of the applicability of such monitoring to the unit in question, unless data or information is brought forward to rebut the assumption. Presumptively acceptable monitoring includes: (a) Presumptively acceptable or required monitoring approaches, established by DEQ in a rule that constitutes part of the applicable implementation plan required pursuant to title I of the FCAA, that are designed to achieve compliance with OAR 340-212-0200 through 340-212-0280 for particular regulated pollutant-specific emissions units; (b) Continuous emission, opacity, or predictive emission monitoring systems that satisfy applicable monitoring requirements and performance specifications contained in OAR 340-212-0210(d); (c) Excepted or alternative monitoring methods allowed or approved pursuant to 40 CFR part 75; (d) Monitoring included for standards exempt from OAR 340-212-0200 through 340-212-0280 pursuant to OAR 340-212-0200(2)(a)(A) through (F) to the extent such monitoring is applicable to the performance of the control device and associated capture system for the regulated pollutant-specific emissions unit; and (e) Presumptively acceptable monitoring methods identified in guidance by EPA. (3)(a) Except as provided in section (4), the owner or operator must submit control device and process and capture system, if applicable, operating parameter data obtained during the conduct of the applicable compliance or performance test conducted under conditions specified by the applicable rule. If the applicable rule does not specify testing conditions or only partially specifies test conditions, the performance test generally must be conducted under conditions representative of maximum emissions potential under anticipated operating conditions at the regulated pollutant-specific emissions unit. Such data may be supplemented by engineering assessments and manufacturer's recommendations to justify the indicator ranges or, if applicable, the procedures for establishing such indicator ranges. Emission testing is not required to be conducted over the entire indicator range or range of potential emissions; (b) The owner or operator must document that no changes to the regulated pollutant-specific emissions unit, including the control device and capture system, have taken place that could result in a significant change in the control system performance or the selected ranges or designated conditions for the indicators to be monitored since the performance or compliance tests were conducted. (4) If existing data from unit-specific compliance or performance testing specified in section (3) are unavailable, the owner or operator: (a) Must submit a test plan and schedule for obtaining such data in accordance with section (5); or (b) May submit indicator ranges, or procedures for establishing indicator ranges, that rely on engineering assessments and other data, if the owner or operator demonstrates that factors specific to the type of monitoring, control device, or regulated pollutant-specific emissions unit make compliance or performance testing unnecessary to establish indicator ranges at levels that satisfy the criteria in OAR 340-212-0210(1). (5) If the monitoring plans submitted by the owner or operator require installation, testing, or other necessary activities before conducting the monitoring for purposes of OAR 340-212-0200 through 340-212-0280, the owner or operator must include an implementation plan and schedule for installing, testing and performing any other appropriate activities before conducting the monitoring. The implementation plan and schedule must provide for conducting the monitoring as expeditiously as practicable after DEQ approves the monitoring plans in the Oregon Title V Operating Permit pursuant to OAR 340-212-0240. In no case may the schedule for completing installation and beginning operation of the monitoring exceed 180 days after approval of the permit. (6) If a control device is common to more than one regulated pollutant-specific emissions unit, the owner or operator may submit monitoring plans for the control device and identify the regulated pollutant-specific emissions units affected and any process or associated capture device conditions that must be maintained or monitored in accordance with OAR 340-212-0210(1) rather than submit separate monitoring plans for each regulated pollutant-specific emissions unit. (7) If a single regulated pollutant-specific emissions unit is controlled by more than one control device that is similar in design and operation, the owner or operator may submit monitoring plans that apply to all the control devices and identify the control devices affected and any process or associated capture device conditions that must be maintained or monitored in accordance with OAR 340-212-0210(1) rather than submit a separate description for each control device.
