A. For the purpose
					 of applying this article in the context of the Regulations for the Control and
					 Abatement of Air Pollution and related uses, the words or terms shall have the
					 meanings given them in subsection C of this section.
B. Unless otherwise required by context, all
					 terms not defined herein shall have the meanings given them in 9VAC5-80
					 (Permits for Stationary Sources), 9VAC5-10 (General Definitions), or commonly
					 ascribed to them by recognized authorities, in that order of
					 priority.
C. Terms defined.
"Best available control technology" or "BACT" means, as
						used in 9VAC5-50-260, an emissions
						limitation (including a visible emission standard) based on the maximum degree
						of emission reduction for any pollutant which would be emitted from a new
						stationary source or project which the board, on a case-by-case basis, taking
						into account energy, environmental and economic impacts and other costs,
						determines is achievable for the new stationary source or project through the
						application of production processes or available methods, systems and
						techniques, including fuel cleaning or treatment or innovative fuel combustion
						techniques 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 in Article 5
						(9VAC5-50-400 et seq.) of this part
						or Article 1 (9VAC5-60-60 et seq.) or Article 2
						(9VAC5-60-90 et seq.) of Part II of
						9VAC5-60 (Hazardous Air Pollutant Sources). If the board determines that
						technological or economic limitations on the application of measurement
						methodology to a particular emissions unit would make the imposition of an
						emission standard infeasible, a design, equipment, work practice, operational
						standard, or combination of them, may be prescribed instead of requiring the
						application of best available control technology. Such standard shall, to the
						degree possible, set forth the emission reduction achievable by implementation
						of such design, equipment, work practice or operation, and shall provide for
						compliance by means which achieve equivalent results. In determining best
						available control technology for stationary sources subject to Article 6
						(9VAC5-80-1100 et seq.) of Part II
						of 9VAC5-80 (Permits for Stationary Sources), consideration shall be given to
						the nature and amount of the emissions, emission control efficiencies achieved
						in the industry for the source type, total cost effectiveness, and where
						appropriate, the cost effectiveness of the incremental emissions reduction
						achieved between control alternatives.
