As used in these Standards and Regulations:

(1) “Air pollutant” means any air pollution agent or combination of such agents, including any physical, chemical, biological, radioactive (including source material, special nuclear material, and byproduct material) substance or matter which is emitted into or otherwise enters the ambient air. Such term includes odorous substances and any precursors to the formation of any pollutant, to the extent that the agent or combination of such agents is identified in any federal or territory rules as precursors.

(2) “Air pollution” means the presence in the outdoor atmosphere of one or more substances in such quantities and duration as is or tends to be injurious to human health or welfare, plant or animal life or property, or would unreasonably interfere with the enjoyment of life or property.

(3) “Air pollution control equipment” means equipment or a facility of a type intended to eliminate, prevent, reduce, or control the emissions of any regulated or hazardous air pollutant to the atmosphere.

(4) “Air pollution emission source,” “emission source,” “stationary air pollution source” or “source” means any piece of equipment or activity at a building, structure, facility, or installation that emits or may emit any air pollutant. For this definition, “Building, structure, facility, or installation” means all of the air pollutant emitting activities which belong to the same industrial grouping, are located on one or more contiguous or adjacent properties, and are under the control of the same person (or persons under common control) except for the activities of any vessel which are not regulated under the federal Clean Air Act. Air pollutant emitting activities shall be considered as part of the same industrial grouping if they belong to the same “major group” (i.e. which have the same first two digit code) as described in the Standard Industrial Classification Manual, 1987).

(5) “Allowable emissions” means the emissions of an air pollution emission source calculated using the maximum rated capacity of the source, or, if the source is subject to federally enforceable limits which restrict the operating rate, capacity, or hours of operations, or any combination of these, then the maximum of the source, considering federally enforceable limits, and the most stringent of the following:

(A)The applicable standards set forth in 40 CFR Parts 60, 61, and 63;

(B) Any American Samoa implementation plan emission limitation, including those with future compliance dates; and

(C) The emission rates specified in a federally enforceable permit condition, including those with future compliance dates.

(6) “Applicant” means any person who submits an application for a permit.

(7) “ASEPA” means the American Samoa Environmental Protection Agency or its authorized agents.

(8) “ASCA” means the American Samoa Code Annotated.

(9) “Best available control technology” means an emissions limitation including a visible emission standard based on the maximum degree of reduction for each pollutant subject to regulation approved pursuant to the Clean Air Act which would be emitted from any proposed air pollution emission source or modification which the executive secretary, on a cases-by-case basis, taking into account energy, environmental, and economic impacts and other costs, determines is achievable for such source or modification through application of production processes or available methods, systems, and techniques, including fuel cleaning or treatment or innovative fuel combustion for control of such pollutant. In no event shall application of best available control technology result in emissions of any pollutant which would exceed the emissions allowed by any applicable standard promulgated pursuant to 40 CFR Parts 60, 61, and 63. If the executive secretary determines that technological or economic limitations on the application of measurement methodology to a particular emissions unit would make the imposition of an emissions standard infeasible, a design, equipment, work practice, operational standard or combination thereof, may be prescribed instead to satisfy the requirement for the application of best available control technology. Such standard shall, to the degree possible, set forth the emissions reduction achievable by implementation of such design, equipment, work practice, or operation, and shall provide for compliance by means which achieve equivalent results.
