"Actual emissions" means the actual rate of emissions of a pollutant from any stationary source or emissions unit. In general, actual emissions as of a particular date shall equal the highest annual rate, in tons per calendar year, at which the stationary source or emissions unit actually emitted a pollutant during the consecutive five-year period which precedes the particular date and which is representative of normal stationary source or emissions unit operation. The department may allow the use of a different historical time period upon a determination that it is more representative of normal stationary source or emissions unit operation. Actual emissions shall be calculated using the stationary source's or emissions unit's actual operating hours, production rates, and types of materials processed, stored, or combusted during the selected time period.
"Allowable emissions" means the emission rates of a stationary source or emissions unit calculated by using the maximum rated capacity of the emissions units within the stationary source or emissions unit (unless the stationary source or emissions unit is subject to state or federally enforceable limits which restrict the operating rate or hours of operation or both) and the most stringent of the following:
"Complete application" or "complete request" means that the application or request contains all the information necessary for processing the application or request. Designating an application or request complete for purposes of permit processing does not preclude the department from requesting or accepting additional information.
"Contributing to a violation" means, in reference to the potential of a stationary source or emissions unit to emit any of the following pollutants, an air quality impact greater than any of the following amounts:
Carbon monoxide -- 500 µg/m3, 8-hour average
Carbon monoxide -- 2,000 µg/m3, 1-hour average
Nitrogen dioxide -- 1 µg/m3, annual average
PM10 -- 1 µg/m3, annual average
PM10 -- 5 µg/m3, 24-hour average
Sulfur dioxide -- 1 µg/m3, annual average
Sulfur dioxide -- 5 µg/m3, 24-hour average
Sulfur dioxide -- 25 µg/m3, 3-hour average
"Emissions cap" means any limitation on the rate of emissions of any regulated air pollutant from one or more emissions units established and identified as an emissions cap in any permit issued pursuant to the new source review program or operating permit program.
"Emissions unit" means any part of a stationary source which emits or would have the potential to emit any regulated air pollutant.
"Enforceable as a practical matter" means that the permit contains emission limitations that are enforceable by the department and meet the following criteria:
"Existing stationary source" means any stationary source other than a new source.
"Federally enforceable" means all limitations and conditions which are enforceable by the administrator and citizens under the federal Clean Air Act or that are enforceable under other statutes administered by the administrator. Federally enforceable limitations and conditions include, but are not limited to, the following:
"General permit" means a permit issued under this article that meets the requirements of 9VAC5-80-1030.
"Major stationary source" means any stationary source which emits, or has the potential to emit, 100 tons or more per year of any regulated air pollutant.
"New source" means any stationary source (or portion of it), the construction or relocation of which commenced on or after March 17, 1972, and any stationary source (or portion of it), the reconstruction of which commenced on or after December 10, 1976.
"New source review program" means a program for the preconstruction review and permitting of new sources or emissions units or expansions to existing ones in accordance with regulations promulgated to implement the requirements of §§ 110(a)(2)(C), 165 (relating to permits in prevention of significant deterioration areas) and 173 (relating to permits in nonattainment areas) of the federal Clean Air Act.
"Nonattainment condition" means a condition where any area is shown by air quality monitoring data or which is shown by an air quality impact analysis (using modeling or other methods determined by the department to be reliable) to exceed the levels allowed by the ambient air quality standard for a given pollutant, regardless of whether such demonstration is based on current or future emissions data.
"Owner" means any person, including bodies politic and corporate, associations, partnerships, personal representatives, trustees and committees, as well as individuals, who owns, leases, operates, controls or supervises a stationary source.
"Potential to emit" means the maximum capacity of a stationary source or emissions unit to emit a pollutant under its physical and operational design. Any physical or operational limitation on the capacity of the stationary source or emissions unit to emit a pollutant, including 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 if the limitation or the effect it would have on emissions is state or federally enforceable. Secondary emissions do not count in determining the potential to emit of a stationary source or emissions unit.
"Regulated air pollutant" means any of the following:
"Secondary emissions" means emissions which would occur as a result of the construction or operation of a major stationary source, but do not come from the major stationary source itself. Secondary emissions include emissions from any offsite support facility which would not be constructed or increase its emissions except as a result of the construction or operation of the major stationary source. Secondary emissions do not include any emissions which come directly from a mobile source, such as emissions from the tailpipe of a motor vehicle, from a train, or from a vessel.
"State-enforceable" means all limitations and conditions which are enforceable as a practical matter, including those requirements developed pursuant to 9VAC5-170-160, requirements within any applicable order, regulation of the board, or variance, and any permit requirements established pursuant to 9VAC5 Chapter 80 (9VAC5-80-10 et seq.).
"Stationary source" means any building, structure, facility or installation which emits or may emit any air pollutant. A stationary source shall include all of the 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 the activities of any vessel. 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 two-digit code) as described in the Standard Industrial Classification Manual (see 9VAC5-20-21).
"Synthetic minor" means a stationary source whose potential to emit is constrained by state-enforceable limits, by federally enforceable limits, or by both so as to place that stationary source below the threshold at which it would be subject to permit or other requirements in regulations of the board or in the federal Clean Air Act.
