Rule 3745-15-04 | Measurement of emissions of air contaminants.


(A) The director may require any persons responsible for emission of air contaminants to make or have made tests to determine the emission of air contaminants from any source whenever the director has reason to believe that an emission in excess of that allowed by these rules is occurring or has occurred from time to time. All tests shall be conducted by qualified persons and the results calculated in accordance with test procedures approved by the director. The owner or the owner's authorized agent shall notify the director in writing of the time, place, and person who will conduct the tests and the director or the director's authorized representative shall be permitted to witness the tests. The director shall be furnished with a written report of test results no later than thirty days after completion of the tests and such report shall be signed by the person or persons responsible for the tests. The director may reject the results of any compliance test which is not performed in accordance with approved test procedures or which is performed without the advance notice and information required by this paragraph.

(B) The director may conduct tests of emissions of air contaminants from any source. Upon request of the director the person responsible for the source to be tested shall provide necessary holes in stacks or ducts and such other safe and proper sampling and testing facilities exclusive of instruments and sensing devices as may be necessary for proper determination of the emission of air contaminants.

(C) The director may install, or require the owner or operator of any source of air contamination, at the owner or operator's expense, to install, use, and maintain monitoring equipment, and to sample the owner or operator's emissions in accordance with methods approved by the director.
