1. (1) The owner or operator shall submit to the department monitoring that satisfies the design requirements in ARM 17.8.1504 through 17.8.1506. The submission shall include the following information:

   1. (a) the indicators to be monitored to satisfy ARM 17.8.1504(1) (a) and (b) ;
   2. (b) the ranges or designated conditions for such indicators, and the process by which such indicator ranges or designated conditions shall be established, or revised;
   3. (c) the performance criteria for the monitoring to satisfy ARM 17.8.1505(1) ; and
   4. (d) if applicable, the indicator ranges and performance criteria for a CEMS, COMS or PEMS pursuant to ARM 17.8.1506, including the process by which indicator ranges or designated conditions shall be established or revised.

2. (2) As part of the information submitted, the owner or operator shall submit a justification for the proposed elements of the monitoring. If the performance specifications proposed to satisfy ARM 17.8.1505(1) (b) or (c) include differences from manufacturer recommendations, the owner or operator shall explain the reasons for the differences between the requirements proposed by the owner or operator and the manufacturer's recommendations or requirements. The owner or operator also shall 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 department 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 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 presumption. Presumptively acceptable monitoring includes:

   1. (a) presumptively acceptable or required monitoring approaches, established by the department 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 this subchapter for particular pollutant-specific emissions units;
   2. (b) continuous emission, opacity or predictive emission monitoring systems that satisfy applicable monitoring requirements and performance specifications as specified in ARM 17.8.1506;
   3. (c) excepted or alternative monitoring methods allowed or approved pursuant to 40 CFR part 75; and
   4. (d) monitoring included for standards exempt from this subchapter pursuant to ARM 17.8.1503(2) (a) or (f) to the extent such monitoring is applicable to the performance of the control device (and associated capture system) for the pollutant-specific emissions unit.
   5. (e) presumptively acceptable monitoring identified in guidance by the EPA. Such guidance may be sufficient for purposes of this rule and ARM 17.8.1508(1) and (2) , or additional information may be required.
