(1) Vehicles as defined by the Motor Vehicle Act of the Ohio Revised Code, or aircraft.
(2) Internal combustion engines of less than 1500 cubic inches displacement or any engine used solely as a standby source of motive power.
(3) Source operations utilized exclusively in connection with any structure which is designed for and used exclusively as a dwelling for not more than two families.
(4) Source operations or emission points or emissions where all of the following requirements are met:
(A) The air contaminants shall be purposely emitted for the sole purpose of a specific beneficial use of a major portion of such air contaminants;
(B) The air contaminants shall be confined, essentially in their entirety, to the area in which such beneficial use is obtained; and
(C) The quantity and nature of the air contaminants, and the proportion of air contaminant used in relation to amounts of other materials involved in the beneficial use of air contaminants, shall conform to accepted practice in the type of use employed.
(5) Experimental operations where all of the requirements of the following are met:
(A) The purpose of the operation and the need for the exception arise from investigation, experiment or research to advance the state of knowledge or to improve technique;
(B) The Air Pollution Control Officer has given express prior approval which shall include limitation of time; and
(C) The health officer having jurisdiction has been.consulted and has concurred in all terms of the exceptions.
(6) Open outdoor fires, except as otherwise regulated by ordinance, and fires used only for recreational purposes, residential heating or occasional cooking of food for human beings, where such use is accomplished in a fireplace or barbecue pit.
(7) Laboratory equipment used exclusively for chemical or physical analysis or experimentation.
(8) Equipment for inspection of metal products.
(9) Portable brazing, soldering or welding equipment.
(10) Comfort air conditioning or comfort ventilating systems which are not designed to remove air contaminants generated by or released from specific units of equipment.
(11) Any emission point which is not an intended opening, and from which no significant quantities of air contaminants are emitted.
(12) Smoke generators which are intentionally operated for purposes of training observers in observing the shade of opacity of emissions.
(b) Upset Conditions, Breakdown or Scheduled Maintenance. Emissions exceeding any of the limits established in this chapter as a direct result of upset conditions in or breakdown of any air pollution control equipment or related operating equipment, or as a direct result of the shutdown of such equipment for scheduled maintenance, shall not be deemed to be in violation of the rules establishing such limits, provided all of the following requirements are met:
(1) Such occurrence shall have been reported to the officers of the Air Pollution Control Office as soon as reasonably possible. For scheduled maintenance, such report shall be submitted at least twenty-four hours prior to shutdown, and for upset conditions or breakdown, such report shall in any case be made within four hours of the occurrence;
(2) This subsection (b) shall not apply to scheduled maintenance of air pollution control equipment, except in those cases where the maximum reasonable effort, including off-shift labor where required, has been made to accomplish such maintenance during periods of nonoperation of any related source operations;
(3) The person responsible for such emissions shall, with all practicable speed, initiate and complete appropriate reasonable action to correct the conditions causing such emissions to exceed such limits; to reduce the frequency of occurrence of such conditions; to minimize the amount by which such limits are exceeded, and to reduce the length of time for which such limits are exceeded, and shall, upon request of the Air Pollution Control Officer, submit to the Officer a full report of such occurrence, including a statement of all known causes and of the scheduling and nature of the actions to be taken pursuant to this subsection (b).
