When used in these regulations, the following definitions apply:

   (a) "Clear coat" means a coating which lacks color and opacity.

   (b) "Coating application system" means all operations and equipment which applies, conveys, and dries a surface coating.

   (c) "Commission" means the Commission on Pollution Control and Ecology of the State of Arkansas.

   (e) "Cutback asphalt" means asphalt cement which has been liquefied by blending with petroleum solvents (diluents). Upon exposure to atmospheric conditions, the diluents evaporate, leaving the asphalt cement to perform its function.  

   (f) "Department" means the Arkansas Department of Pollution Control and Ecology.

   (g) "Director" means the Director of the "Department".

   (h) "Delivery vessel" means tank trucks or trailers equipped with a storage tank and used for the transport of gasoline from sources of supply to stationary tanks of gasoline dispensing facilities.  

   (i) "EPA" means the United States Environmental Protection Agency.

   (j) "Existing source" means any source of volatile organic compounds other than a new source.

   (k) "Extreme performance coating" means coatings designed for harsh exposure or extreme environmental conditions.

   (l) "Gasoline" means a petroleum distillate having a Reid vapor pressure of 27.6 kPa (4 psi) or greater that is used as fuel for internal combustion engines.

   (m) "Gasoline dispensing facility" means any site where gasoline is dispensed to motor vehicle gasoline tanks from stationary storage tanks.

   (n) "Gasoline tank truck" means tank trucks or trailers equipped with a storage tank and used for the transport of gasoline from sources of supply to stationary storage tanks or to gasoline bulk facilities.

   (o) "Low solvent coating" means coatings which contain less organic solvent that the conventional coatings used by the industry. Low solvent coatings include water borne, high solids, electrode position and powder coatings.

   (p) "Lowest Achievable Emission Rate" means for any source, that rate of emissions which reflects the most stringent emission limitation which is contained in the implementation plan of any State for such class or category of source, unless the owner or operator of the proposed source demonstrates that such limitations are not achievable, or the most stringent emission limitation which is achieved in practice by such class or category of source, whichever is more stringent. In no event shall the application of this term permit a proposed new or modified source to emit any pollutant in excess of the amount allowable under applicable New Source Standards of  Performance.
 
   (q) "Major source" means any stationary source which has the potential to emit 100 tons or more per year of volatile organic compounds.

   (r) "Modification" means any physical change in, or change in the method of operation of, a stationary source which increases the amount of any air pollutants emitted by such source or which results in the emission of any other air pollutants not previously emitted.

   (s) "New source" means any stationary source of volatile  organic compounds, the construction or modification of which is commenced after July 1, 1979.

   (t) "New Source Standard of Performance" means those standards which are adopted by the EPA pursuant to the provisions of Section 111 of the federal Clean Air Act.

   (u) "Operator" means any person who leases, operates, controls, or supervises any source, facility or equipment affected by these regulations.  

   (v) "Owner" means any person who has legal or equitable title to any source, facility, or equipment affected by these  regulations.

   (w) "Person" means any individual or other legal entity or their legal representative or assignee.

   (x) "Plan" means the Arkansas Plan of Implementation for Air Pollution Control.  

   (y) "Potential to emit" means the capability at maximum capacity to emit a pollutant in the absence of air pollution control equipment. "Air pollution control equipment" includes control equipment which is not, aside from air pollution control laws and regulations, vital to production of the normal product of the source or to its normal operation. Annual potential shall be based on the maximum annual rated capability of the source, unless the source is subject to enforceable permit conditions which limit the annual hours of operation. Enforceable permit conditions on the type or amount of material combusted or processed may be used in determining the potential emission rate of a source.

   (z) "Prime coat" means the first of two or more films of  coating applied to a metal surface.

   (aa) "Reasonably Available Control Technology" (RACT) means the lowest emission limit that a particular source is capable of meeting by the application of control technology that is reasonably available considering technological and economic feasibility. It may require technology that has been applied to similar, but not necessarily identical source categories.

   (bb) "Single coat" means one film coating applied to a metal surface.

   (cc) "Source" means any structure, building facility, equipment, process, installation, or operation (or combination thereof) which is located on one or more contiguous or adjacent properties, which is under common management, and which emits  volatile organic compounds.  

   (dd) "Top coat" means the final film or series of films or coatings applied in a two coat (or more) operation.

   (ee) "Vapor collection system" means a vapor transport system which used direct displacement by the gasoline being transferred to force vapors from the vessel being loaded into either a vessel being unloaded or a vapor control system or vapor holding tank.

   (ff) "Vapor control system" means a system that prevents  release to the atmosphere of gasoline vapors in excess of 80 milligrams per liter of gasoline loaded (4.7 grains per liter).

   (gg) "Volatile organic compounds" (VOC) means any compound of carbon that has a vapor pressure greater than 0.1 millimeters of mercury at standard conditions excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, and ammonium carbonates. The term includes hydrocarbons controlled by New Source Standards of Performance and by the National Ambient Air Quality Standards.

   (hh) Unless manifestly inconsistent therewith, terms and  phrases used herein shall have same meaning as used in the Arkansas Water and Air Pollution Control Act and the federal Clean Air Act.

   (ii) "Crude oil" means a naturally occurring mixture consisting of hydrocarbons and/or sulfur, nitrogen, and/or oxygen derivatives of hydrocarbons and which is a liquid in the reservoir and at standard conditions.

   (jj) "Custody transfer" means the transfer of produced crude oil and/or condensate, after processing and/or treating in the producing operations, from storage tanks or automatic transfer facilities to pipelines or any other forms of transportation.

   (kk) "External floating roof" means a storage vessel cover in an open tank top consisting of a double deck or pontoon single deck which rests upon and is supported by the petroleum liquid being contained and is equipped with a closure seal or seals to close the space between the roof edge and tank shell.

   (ll) "Liquid-mounted" means a primary seal mounted so the bottom of the seal covers the liquid surface between the tank shell and the floating roof.

   (mm) "Vapor-mounted" means a primary seal mounted so there is an annular vapor space underneath the seal. The annular vapor space is bounded by the bottom of the primary seal, the tank shell, the liquid surface, and the floating roof.

   (nn) "True vapor pressure" means the equilibrium partial  pressure exerted by a petroleum liquid as determined in accordance with methods described in American Petroleum Institute (API) Bulletin 2517, Evaporation Loss from External Floating Roof Tanks, 1980. The API procedure may not be applicable to some high viscosity or high pour crudes. Available estimates of true vapor pressure may be used in special cases such as these.
