Rule R307-165 - Emission Testing
Section R307-165-4 - Test Conditions

(1) The production rate during all stack testing shall be no less than 90% of the maximum production rate achieved in the previous three years. If the desired production rate is not achieved at the time of the test, the maximum production rate shall be 110% of the tested achieved rate, but not more than the maximum allowable production rate. This new allowable maximum production rate shall remain in effect until successfully tested at a higher rate. The owner or operator shall request a higher production rate when necessary. Testing at no less than 90% of the higher rate shall be conducted. A new maximum production rate of 110% of the new rate will then be allowed if the test is successful. This process may be repeated until the maximum allowable production rate is achieved.

(2) During the stack testing, the owner or operator shall burn fuels or combinations of fuels, use raw materials, and maintain process conditions representative of normal operations of the emissions unit.

(3) The owner or operator shall operate the emissions unit under such other relevant conditions as the director shall specify.
