Section 326IAC3-6-3. Emission testing

   (a) Department staff may observe field test procedures and source or emissions unit operation during the emission test.

  (b) The owner or operator of a source or emissions unit shall conduct all emission tests as follows:

(1) The emissions unit being tested shall be operating according to clause (A) or (B), except as allowed under clause (C), as follows:

(A) At a minimum, ninety-five percent (95%) of the permitted maximum emissions unit operating capacity description.

(B) Under conditions of worst case emissions, and if the worst case emission condition is not known, then the worst case emission condition shall be assumed to be the maximum process or operating rate of the emissions unit as listed in the permit's emissions unit description.

(C) Under other capacities or conditions as specified in an applicable requirement or approved by the department. As used in this clause, "capacity" means the design capacity of the emissions unit or other operating capacities agreed to by the owner or operator of the emissions unit and the department, including, but not limited to, process conditions when the department believes that changes in the operating capacities or operating conditions have the potential to affect emission levels.

(2) All test runs for a given pollutant shall be conducted within forty-eight (48) hours unless process variables or mandatory test lengths of greater than two (2) hours make this impracticable. In these cases, the testing shall be conducted on consecutive days. Other periods or duration may be approved by the commissioner if specific testing circumstances require a longer testing time frame.

  (c) Emissions units subject to 326 IAC 12, 326 IAC 14, or 326 IAC 20 shall be tested under conditions as specified in the applicable provision for that emissions unit in 40 CFR 60*, 40 CFR 61*, or 40 CFR 63* and this rule where appropriate.

  (d) The owner or operator of a source or emissions unit shall make available at the test site calibration results of the various sampling components. The information shall include the following:

(1) The date or dates the test was performed.

(2) The methods used.

(3) The calibration data.

(4) The results.

All components requiring calibration shall be calibrated within sixty (60) days prior to the actual test date. Post-test calibrations shall be performed on the components not later than forty-five (45) days after the actual test date. Components requiring calibration are listed in the federal test methods specified in section 5 of this rule.

  (e) The department may perform or require the performance of audits of equipment or procedures associated with the test series up to the time of the actual performance of the test, between test runs, or following the test series. The department reserves the right to perform or observe all associated analyses.

  (f) The original or a photocopy of the raw field data generated during the test series shall be provided to the department observer upon request if the request may be reasonably met under the existing circumstances.
