Affected: IC 13-15; IC 13-17
Sec. 8.5.
(a) Owners and operators of a large affected unit subject to this rule may use an alternative monitoring method and comply with the reporting requirements established in an operating permit in lieu of the requirements in sections 3 through 8 of this rule, if:(1) approved by the department as sufficient to demonstrate compliance with the ozone season NOx emissions budget established under section 9 of this rule; and(2) consistent with the requirements in this section.(b) To request use of alternative monitoring and reporting requirements in this section, the owner or operator of a large affected unit shall submit an application for an operating permit or an application for a modification to an existing operating permit issued in accordance with 326 IAC 2.(c) The application must include all of the following: (1) An indication of which of the following alternatives is being requested:(A) Monitoring in accordance with 40 CFR 60*.(B) Monitoring in accordance with 40 CFR 75*, except that:(i) references to the "Administrator" in 40 CFR 75* means the department; and(ii) reporting of data to U.S. EPA through electronic means in accordance with 40 CFR 75*, Subpart G, does not apply.(C) Monitoring of heat input and fuel use using a fuel flowmeter, with NOx emission rate determined through an emissions monitoring system certified, operated, and maintained in accordance with 40 CFR 60*.(D) Monitoring of heat input and fuel use and an approved emission factor for determination of NOx emissions. Liquid or gaseous fuel use must be measured using meters calibrated to the levels of accuracy specified in:(i) Section 2.1.5 of 40 CFR 75, Appendix D*;(iii) the ASME standards at 40 CFR 98.7 *; or(iv) other procedures recommended by the manufacturer.(2) A description of the proposed monitoring procedures, including how:(A) data will be obtained, recorded, and quality assured; and(B) NOx emissions will be accounted for during periods of missing data, such as periods of maintenance or malfunction.(3) Emission monitoring data must be reported as provided in subsection (e).(4) If monitoring of heat input and fuel use and an approved emission factor under subdivision (1)(D) is requested as the alternative, an emission factor analysis evaluating potential emission factors in pounds of NOx emitted per unit of fuel and heat input, for each fuel type, based on one (1) of the following: (A) U.S. EPA's Compilation of Air Pollutant Emissions Factors, AP-42*, as described in 326 IAC 1-1-3.5.(B) A valid stack test using 40 CFR 60, Appendix A, Method 3*, Method 7*, and Method 19*, conducted within the previous two (2) years from the date of the application submittal, if available.(C) An analysis of continuous emission monitoring data representative of current operating conditions.(D) An analysis of other relevant data or emission factors, if available.(5) If monitoring and annual reporting of ozone control period NOx emissions in accordance with 40 CFR 60 * under subdivision (1)(A) or (1)(C) is requested, an explanation for how the amount of NOx emissions in tons per ozone control period will be determined from the NOx emission rate data in accordance with 40 CFR 60*.(6) If alternative monitoring and reporting is requested to begin within an ozone control period, a description of the transition process that ensures there will not be gaps in data collection and reporting of ozone control period NOx emissions.(d) Prior to the use of alternative monitoring and reporting, one (1) of the following must be specified in an operating permit issued in accordance with 326 IAC 2: (1) Applicable terms and conditions, including monitoring and reporting requirements in accordance with 40 CFR 60* or 40 CFR 75 *.(2) An emission factor and monitoring procedure for fuel use and heat input.(e) The owner or operator of a large affected unit subject to alternative monitoring and reporting under this section shall meet all of the following: (1) Comply with all terms and conditions specified in the operating permit.(2) Install all data collection and recording systems required for alternative monitoring.(3) Record and report the data from the monitoring systems required under this section in accordance with the terms and conditions in the operating permit.(4) By April 15 each year, report NOx emissions in tons to the department, as determined using the approved alternative monitoring procedures, for the previous ozone control period.(5) If alternative monitoring is based on an approved emission factor, the following requirements apply:(A) Conduct stack tests to demonstrate the approved emission factor continues to be representative of current operating conditions.(B) If the emissions factor analysis submitted in accordance with subsection (c)(2) did not include a stack test, an initial stack test must be conducted within ninety (90) days of permit issuance.(C) Ongoing stack tests must be conducted at least once every five (5) years from the date of approval of the alternative monitoring request.(D) Stack tests must be conducted in accordance with a test method specified in the operating permit and reported to the department within forty-five (45) days of the test.(E) If a stack test indicates an emission factor may require upward adjustment, the owner or operator shall use the revised emission factor to report NOx emissions in tons per ozone control period and submit an application for a modification to an operating permit within sixty (60) days of receiving stack test results.(6) Maintain records in accordance with the terms and conditions in the operating permit for a period of not less than five (5) years from the date the records are created. These records must be made available to the department upon request.(f) An owner or operator of a large affected unit subject to this section shall not do the following: (1) Operate the unit so as to discharge, or allow to be discharged, NOx emissions to the atmosphere during an ozone control period without accounting for all emissions in accordance with the applicable provisions of this section.(2) Retire or permanently discontinue use of the monitoring system, or any component thereof, except when discontinuing use of alternative monitoring and reporting in accordance with this section and resuming compliance with monitoring and reporting requirements in accordance with sections 3 through 8 of this rule. This may only occur outside of an ozone control period.(g) This section does not authorize exceptions or alternatives to any 40 CFR Part 75 monitoring requirements that apply to a source under a different legal authority.(h) In accordance with the requirements of 40 CFR 51.122(c)(1)(i) *, the department shall report annually to U.S. EPA all NOx emissions reported under this section. *These documents are incorporated by reference.
