Sec. 4.
(a)
Determination of opacity from sources or facilities to which this rule applies
shall be made in accordance with subdivision (1) or (2) as follows:
(1) Determination of opacity by means of
visible emissions readings shall be made in accordance with 40 CFR
60, Appendix
A, Method 9*.
(2) For a source or
facility in compliance with the requirements of
326 IAC 3-5, determination of
compliance with visible emission limitations established in this rule may also
be made in accordance with a source's or facility's continuous monitoring
equipment if determined appropriate by the department or the U.S.
EPA.
(b) This subsection
applies in the event of a conflict between the opacity readings obtained under
subsection (a)(1) and those obtained under subsection (a)(2) for the same time
period. If the conflict occurs, the commissioner may require that the source
perform an audit on the opacity monitoring system consistent with
326 IAC
3-5-2(7)(B). After reviewing the
results of the audit, if performed, enforcement action may be taken based on
the opacity readings obtained under subsection (a)(1) or the opacity readings
obtained under subsection (a)(2). This does not preclude a source from using
the opacity readings obtained under subsection (a)(2) or other relevant
information to refute the findings of the commissioner.
