4. (4) Process rates.

   1. (A) Unless otherwise approved by the division, all federally regulated air pollutant emissions sampling shall be performed with the equipment being tested operating at least at ninety percent (90%) of its permitted capacity.
   2. (B) Emissions results shall be extrapolated to correlate with one hundred percent (100%) of permitted capacity to determine compliance;

5. (5) Testing timeframes. Any equipment that is to be tested at the request of the division shall be tested in accordance with the following timeframes:

   1. (A) Equipment to be constructed or modified shall be tested within sixty (60) days after achieving its maximum permitted production rate, but no later than one hundred eighty (180) days after its initial startup; and
   2. (B) Equipment already operating shall be tested according to the timeframes set forth by the division; and

6. (6) Testing methods and records.

   1. (A) The division shall require that all applicable testing be performed using the methods described in:
