Terms and phrases used in this regulation which are not explicitly defined herein shall have the same meaning as those terms which are used in the federal Clean Air Act. For purposes of this regulation:
"12-month period" means a period of 12 consecutive months determined on a rolling basis with a new 12-month period beginning on the first day of each calender month.
"Actual emissions" means the quantity of federally regulated air pollutants emitted from a stationary source considering emissions control equipment and actual hours of source operation or amount of material processed.
"Commission" means the Commission on Pollution Control and Ecology of the State of Arkansas.

“Modification" means any physical change in, or change in the method of operation of, a stationary source which increases the emission rate of any federally regulated air pollutant over permitted rates or which results in the emission of a federally regulated air pollutant not previously emitted, except that:
(1) Routine maintenance, repair, and replacement shall not be considered a physical change, and
(2) The following shall not be considered a change in the method of operation:
(a) Any change in the production rate, if such change does not exceed the permitted operating capacity of the source;
(b) Any change in the hours of operation, as long as it does not violate applicable air permit conditions; or
(c) The use of an alternate fuel or raw material, as long as it does not violate applicable air permit conditions.

"Owner" means any person who has legal or equitable title to any source, facility, or equipment affected by these regulations.
"Particulate matter" means any airborne finely divided solid or liquid material with an aerodynamic diameter equal to or less than 100 micrometers.
"Particulate matter emissions" means all particulate matter, other than uncombined water, emitted to the ambient air as measured by applicable reference methods, or an equivalent or alternate method, specified in 40 CFR Part 60 Appendix A or by a test method specified in these regulations or any supplement thereto.
"Person" means any individual or other legal entity or their legal representative or assignee.
"Plan" means the Arkansas Plan of Implementation for Air Pollution Control.
"PM10" means particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers as measured by a reference method based on Appendix J of 40 CFR Part 50, or by an equivalent method designated in accordance with 40 CFR Part 53.
"PM10 emissions" means PM10 emitted to the ambient air as measured by an applicable reference method, or an equivalent or alternate method, specified in 40 CFR Part 51, Appendix M, or by a test method specified in these regulations or any supplement thereto.
"Potential to emit" means the maximum capacity of a stationary source to emit a federally regulated air pollutant under its physical and operational design. Any physical or operational limitation on the capacity of the source to emit a federally regulated air pollutant, including, but not, limited to, air pollution control equipment and restrictions on hours of operation or on the type or amount of material combusted, stored, or processed, shall be treated as part of its design only if the limitation or the effect it would have on emissions is enforceable to the extent it is regulated by the federal Clean Air Act, 42 U.S.C. §§ 7401 et seq. Secondary air emissions do not count in determining the potential to emit of a stationary source.
"Responsible official" means one of the following:
(1) For a corporation: a president, secretary, treasurer, or vice president of the corporation in charge of a principal business function, or any other person who performs similar policy or decision-making functions for the corporation, or a duly authorized representative or such person if the representative is responsible for the overall operation of one or more manufacturing, production, or operating facilities applying for or subject to a permit and either:

"Shutdown" means the cessation of operation of equipment.
"Startup" means the setting in operation of equipment.
"Stationary source" means any building, structure, facility, or installation which emits or may emit any federally regulated air pollutant.
"Volatile organic compounds" (VOC) means any compound of carbon, excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, and ammonium carbonate, which participates in atmospheric photochemical reactions.
(1) This does not include any such organic compound which has been determined by the EPA to have negligible photochemical reactivity, as of the effective date of this regulation. As of the effective date of this regulation, the following compounds have been determined to have negligible photochemical reactivity:
methylene chloride (dicloromethane);
1,1,1-trichloroethane (methyl chloroform);
1,1,1 trichloro-2,2,2-trifluoroethane (CFC-131);
1,2-dichloro 1,1,2,2-tetrafluoroethane (CFC-114);

1-chloro-1,1,1,2 tetrafluoroethane (HCFC-142b);
cyclic, branched, or linear completely methylated siloxanes;
1,1,l,2,3,4,4,5,5,5-decafluoropentane (HFC 43-10mee);
1 chloro-1-fluoroethane (HCFC-151a);
methyl acetate and perfluorocarbon compounds which fall into these classes:
(a) cyclic, branched, or linear, completely fluorinated alkanes;
(b) cyclic, branched, or linear, completely fluorinated ethers with no unsaturations;
(c) cyclic, branched, or linear, completely fluorinated tertiary amines with no unsaturations;
(d) sulfur containing perfluorocarbons with no saturations and with sulfur bonds only to carbon and fluorine.
(2) For purposes of determining compliance with emission limits, VOC will be measured by the test methods in the approved SIP or 40 CFR Part 60, Appendix A, as applicable. Where such a method also measures compounds with negligible photochemical reactivity, these negligibly-reactive compounds may be excluded as VOC if the amount of such compounds is accurately quantified, and such exclusion is approved by the Department.
(3) As a precondition to excluding these compounds as VOC or at any time thereafter, the Department may require an owner or operator to provide monitoring or testing results demonstrating, to the satisfaction of the Department, the amount of negligibly-reactive compounds in the sources's emissions.
