(1)Any person may apply to the director for approval of an alternate test method,an alternate method of control,an
alternate compliance period,an alternate emission limit,or an alternate monitoring schedule.The application [must]shall include
a demonstration that the proposed alternate produces an equal or greater air quality benefit than that required by Rule R307-328,
or that the alternate test method is equivalent to that required by Rule R307-328.The director shall obtain concurrence from EPA
when approving an alternate test method,an alternate method of control,an alternate compliance period,an alternate emission
limit,or an alternate monitoring schedule.
