Section 74:36:11:04 - Testing new fuels or raw materials

The owner or operator of a permitted source may request permission to test a new fuel or raw material to determine if it is compatible with existing equipment and to determine air emission rates before requesting a permit amendment or modification. A complete request shall consist of:

(1) A written proposal that describes the new fuel or raw material;

(2) An estimate of the type and amount of regulated air pollutant emissions that will result from the change; and

(3) The schedule for conducting the test and the duration of the test. In most cases the owner or operator will be allowed to test for a maximum of one week. A request for a test period longer than one week will need additional justification. A test period shall not exceed 180 days.

Within 45 days after receipt of a complete proposal to conduct a test, the department shall notify the owner or operator in writing as to whether or not the department approves the test. If approved, the department's written response shall specify the schedule for conducting the test and outline the test requirements. The requirements may include performance testing, visible emission evaluation, fuel analysis, dispersion modeling, and monitoring of raw material or fuel rates.

If the department determines that the change will increase an emission of a regulated air pollutant or result in the emission of an additional regulated air pollutant, the department shall give public notice of the proposed test for 30 days. The department shall consider all comments received during the 30-day public comment period before making a final decision on the test.

The department will not approve a test if the test would cause or contribute to a violation of a national ambient air quality standard.
