9VAC5-80-1100. Applicability.

A. Except as provided in subsection C of this section, the provisions of this article apply to the construction, reconstruction, relocation or modification of any stationary source.

B. The provisions of this article apply throughout the Commonwealth of Virginia.

C. The provisions of this article do not apply to any stationary source, emissions unit or facility that is exempt under the provisions of 9VAC5-80-1320. Exemption from the requirement to obtain a permit under this article shall not relieve any owner of the responsibility to comply with any other applicable provisions of regulations of the board or any other applicable regulations, laws, ordinances and orders of the governmental entities having jurisdiction. Any stationary source, emissions unit or facility which is exempt from the provisions of this article based on the criteria in 9VAC5-80-1320 but which exceeds the applicability thresholds for any applicable emission standard in 9VAC5 Chapter 40 (9VAC5-40) if it were an existing source or any applicable standard of performance in 9VAC5 Chapter 50 (9VAC5-50) shall be subject to the more restrictive of the provisions of either the emission standard in 9VAC5 Chapter 40 (9VAC5-40) or the standard of performance in 9VAC5 Chapter 50 (9VAC5-50).

D. The fugitive emissions of a stationary source, to the extent quantifiable, shall be included in determining whether it is subject to this article. The provisions of this article do not apply to a stationary source or modification that would be subject to this article only if fugitive emissions, to the extent quantifiable, are considered in calculating the actual emissions uncontrolled emissions rate of the source or net emissions increase.

E. An affected facility subject to Article 5 (9VAC5-50-400 et seq.) of Part II of 9VAC5 Chapter 50 shall not be exempt from the provisions of this article, except where:

1. The affected facility would be subject only to recordkeeping or reporting requirements or both under Article 5 (9VAC5-50-400 et seq.) of 9VAC5 Chapter 50; or

2. The affected facility is constructed, reconstructed or modified at a stationary source which has a current permit for similar affected facilities that requires compliance with emission standards and other requirements that are not less stringent than the provisions of Article 5 (9VAC5-50-400 et seq.) of 9VAC5 Chapter 50.

F. Regardless of the exemptions provided in this article, no owner or other person shall circumvent the requirements of this article by causing or allowing a pattern of ownership or development over a geographic area of a source which, except for the pattern of ownership or development, would otherwise require a permit.

G. No provision of this article shall be construed as exempting any stationary source or emissions unit from the provisions of the major new source review program. Accordingly, no provision of the major new source review program regulations shall be construed as exempting any stationary source or emissions unit from this article.

H. Unless specified otherwise, the provisions of this article are applicable to various sources as follows:

1. Provisions referring to "sources," "new or modified sources, or both" or "stationary sources" are applicable to the construction, reconstruction or modification of all stationary sources (including major stationary sources and major modifications) and the emissions from them to the extent that such sources and their emissions are not subject to the provisions of the major new source review program.

2. Provisions referring to "major stationary sources" are applicable to the construction or reconstruction of all major stationary sources subject to this article. Provisions referring to "major modifications" are applicable to major modifications of stationary sources subject to this article.

3. In cases where the provisions of the major new source review program conflict with those of this article, the provisions of the major new source review program shall prevail.

4. Provisions referring to "state and federally enforceable" or "federally and state enforceable" or similar wording shall mean "state-only enforceable" for terms and conditions of a permit designated state-only enforceable under 9VAC5- 80-1120 F.

"Actual emissions" means the actual rate of emissions (expressed in tons per year) of a pollutant from a stationary source or portion thereof, as determined in accordance with the provisions of this definition.

1. In general, actual emissions as of a particular date shall equal the average rate, in tons per year, at which the unit actually emitted the pollutant during a two-year period that precedes the particular date and that is representative of normal source operation. The board will allow the use of a different time period upon a determination that it is more representative of normal source operation. Actual emissions shall be calculated using the unit's actual operating hours, production rates, and types of materials processed, stored, or combusted during the selected time period.

2. The board may presume that source-specific allowable emissions for the emissions unit are equivalent to the actual emissions of the unit.

3. For any emissions unit which has not begun normal operations on the particular date, actual emissions shall equal the potential to emit of the unit on that date.

"Allowable emissions" means the emission rate of a stationary source calculated by using the maximum rated capacity of the source (unless the source is subject to state and federally enforceable limits which restrict the operating rate or hours of operation, or both) and the most stringent of the following:

3. That, by itself or in or on a piece of equipment, is portable or transportable, meaning designed to be capable of being carried or moved from one location to another. Indications of transportability include, but are not limited to, wheels, skids, carrying handles, dollies, trailers, or platforms.

An internal combustion engine is not a nonroad engine if:

1. The engine is used to propel a motor vehicle or a vehicle used solely for competition, or is subject to standards promulgated under § 202 of the federal Clean Air Act; or

2. The engine otherwise included in subdivision 3 above remains or will remain at a location for more than 12 consecutive months or a shorter period of time for an engine located at a seasonal source.

For purposes of this definition, a location is any single site at a building, structure, facility or installation. Any engine (or engines) that replaces an engine at a location and that is intended to perform the same or similar function as the engine replaced will be included in calculating the consecutive time period. An engine located at a seasonal source is an engine that remains at a seasonal source during the full annual operating period of the seasonal source. A seasonal source is a stationary source that remains in a single location on a permanent basis (i.e., at least two years) and that operates at the single location approximately three months (or more) each year. This paragraph does not apply to an engine after the engine is removed from the location.

"Portable," in reference to emissions units, means an emissions unit that is designed to have the capability of being moved from one location to another for the purpose of operating at multiple locations and storage when idle. Indications of portability include, but are not limited to, wheels, skids, carrying handles, dollies, trailers, or platforms.

"Potential to emit" means the maximum capacity of a stationary source to emit a pollutant under its physical and operational design. Any physical or operational limitation on the capacity of the source 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 only if the limitation or its effect on emissions is state and federally enforceable. Secondary emissions do not count in determining the potential to emit of a stationary source.

"Public comment period" means a time during which the public shall have the opportunity to comment on the new or modified source permit application information (exclusive of confidential information), the preliminary review and analysis of the effect of the source upon the ambient air quality, and the preliminary decision of the board regarding the permit application.

"Reactivation" means beginning operation of an emissions unit that has been shut down.

"Reconstruction" means the replacement of an emissions unit or its components to such an extent that:

1. The fixed capital cost of the new components exceeds 50% of the fixed capital cost that would be required to construct a comparable entirely new unit;

2. The replacement significantly extends the life of the emissions unit; and

3. It is technologically and economically feasible to meet the applicable emission standards prescribed under regulations of the board.

Any determination by the board as to whether a proposed replacement constitutes reconstruction shall be based on:

1. The fixed capital cost of the replacements in comparison to the fixed capital cost of the construction of a comparable entirely new unit;

2. The estimated life of the unit after the replacements compared to the life of a comparable entirely new unit;

3. The extent to which the components being replaced cause or contribute to the emissions from the unit; and

4. Any economic or technical limitations on compliance with applicable standards of performance which are inherent in the proposed replacements.

"Regulated air pollutant" means any of the following:

1. Nitrogen oxides or any volatile organic compound;

2. Any pollutant for which an ambient air quality standard has been promulgated;

3. Any pollutant subject to any standard promulgated under § 111 of the federal Clean Air Act;

5. Any pollutant subject to a regulation adopted by the board.

"Relocation" means a change in physical location of a stationary source or an emissions unit from one stationary source to another stationary source.

"Secondary emissions" means emissions which occur or would occur as a result of the construction, reconstruction, modification or operation of a stationary source, but do not come from the stationary source itself. For the purpose of this article, secondary emissions must be specific, well-defined, and quantifiable; and must affect the same general areas as the stationary source which causes the secondary emissions. Secondary emissions include emissions from any off site support facility which would not be constructed or increase its emissions except as a result of the construction or operation of the 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 any regulation of the board, those requirements developed pursuant to 9VAC5-170-160, requirements within any applicable order or variance, and any permit requirements established pursuant to this chapter.

"State operating permit program" means an operating permit program (i) for issuing limitations and conditions for stationary sources; (ii) promulgated to meet the EPA's minimum criteria for federal enforceability, including adequate notice and opportunity for the EPA and public comment prior to issuance of the final permit, and practicable enforceability; and (iii) codified in Article 5 (9VAC5-80-800 et seq.) of this part.

"Stationary source" means any building, structure, facility or installation which emits or may emit any regulated 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 watercraft or any nonroad engine. 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," as amended by the supplement (see 9VAC5-20-21).

"Synthetic minor" means a stationary source whose potential to emit is constrained by state enforceable and federally enforceable limits, so as to place that stationary source below the threshold at which it would be subject to permit or other requirements governing major stationary sources in regulations of the board or in the federal Clean Air Act.

"Uncontrolled emission rate" means the emission rate from an emissions unit when operating at maximum capacity without air pollution control equipment. Air pollution control equipment includes control equipment that is not vital to its operation, except that its use enables the owner to conform to applicable air pollution control laws and regulations. Annual uncontrolled emissions shall be based on the maximum annual rated capacity (based on 8,760 hours of operation per year) of the emissions unit, unless the emissions unit or stationary source is subject to state and federally enforceable permit conditions that limit the annual hours of operation. Enforceable permit conditions on the type or amount of material combusted, stored, or processed may be used in determining the uncontrolled emission rate of an emissions unit or stationary source. The uncontrolled emission rate of a stationary source is the sum of the uncontrolled emission rates of the individual emissions units. Secondary emissions do not count in determining the uncontrolled emission rate of a stationary source.

(2) Any operation outside the volatile organic compound emissions control areas designated in 9VAC5-20-206.

b. Volatile organic compound storage operations involving any tank of 40,000 gallons or less storage capacity.

5. Vehicle customizing coating operations, if production is less than 20 vehicles per day.

6. Vehicle refinishing operations.

7. Coating operations for the exterior of fully assembled aircraft or marine vessels.

8. Petroleum liquid storage and transfer operations involving petroleum liquids with a vapor pressure less than 1.5 pounds per square inch absolute under actual storage conditions or, in the case of loading or processing, under actual loading or processing conditions (kerosene and fuel oil used for household heating have vapor pressures of less than 1.5 pounds per square inch absolute under actual storage conditions; therefore, kerosene and fuel oil are not subject to the provisions of this article when used or stored at ambient temperatures); and any operation or facility specified below:

a. Gasoline bulk loading operations at bulk terminals located outside volatile organic compound emissions control areas designated in 9VAC5-20-206.

b. Gasoline dispensing facilities.

c. Gasoline bulk loading operations at bulk plants:

(1) With an expected daily throughput of less than 4,000 gallons; or

(2) Located outside volatile organic compound emissions control areas designated in 9VAC5-20-206.

d. Account/tank trucks; however, permits issued for gasoline storage/transfer facilities should include a provision that all associated account/tank trucks meet the same requirements as those trucks serving existing facilities.

e. Petroleum liquid storage operations involving:

(1) Any tank of 40,000 gallons or less storage capacity;

(2) Any tank of less than 420,000 gallons storage capacity for crude oil or condensate stored, processed or treated at a drilling and production facility prior to custody transfer; or

(3) Any tank storing waxy, heavy pour crude oil.

9. Petroleum dry cleaning plants with a total manufacturers' rated solvent dryer capacity less than 84 pounds as determined by the applicable new source performance standard in 9VAC5-50-410.

10. Any addition of, relocation of or change to a woodworking machine within a wood product manufacturing plant provided the system air movement capacity, expressed as the cubic feet per minute of air, is not increased and maximum control efficiency of the control system is not decreased.

11. Wood sawmills and planing mills primarily engaged in sawing rough lumber and timber from logs and bolts, or resawing cants and flitches into lumber, including box lumber and softwood cut stock; planing mills combined with sawmills; and separately operated planing mills that are engaged primarily in producing surfaced lumber and standard workings or patterns of lumber. This also includes facilities primarily engaged in sawing lath and railroad ties and in producing tobacco hogshead stock, wood chips, and snow fence lath. This exemption does not include any facility that engages in the kiln drying of lumber.

12. Exhaust flares at natural gas and coalbed methane extraction wells.

C. The exemption of new and relocated sources shall be determined as specified below:

1. Stationary sources with a potential to emit at rates less than all of the emission rates specified below shall be exempt from the provisions of this article pertaining to construction or relocation.

2. Facilities exempted by subsection B of this section shall not be included in the determination of potential to emit of a stationary source for purposes of exempting sources under this subsection.

3. If the particulate matter (PM₁₀) emissions for a stationary source can be determined in a manner acceptable to the board and the stationary source is deemed exempt using the emission rate for particulate matter (PM₁₀), the stationary source shall be considered to be exempt for particulate matter. If the emissions of particulate matter (PM₁₀) cannot be determined in a manner acceptable to the board, the emission rate for particulate matter shall be used to determine the exemption status.

D. The exemption of modified and reconstructed sources shall be determined as specified below:

1. Stationary sources with net emissions increases less than all of the emission rates specified below shall be exempt from the provisions of this article pertaining to modification or reconstruction.

2. Facilities exempted by subsection B of this section shall not be included in the determination of net emissions increase of a stationary source for purposes of exempting sources under this subsection. However, any other increases and decreases in actual emissions the uncontrolled emission rate at the source that are concurrent with a particular change shall be included in the determination of net emissions increase of a stationary source for purposes of exempting sources under this subsection, and if the change is not exempt, the other increases shall be subject to 9VAC5-50-260 C.

3. If the particulate matter (PM₁₀) emissions for a stationary source can be determined in a manner acceptable to the board and the stationary source is deemed exempt using the emission rate for particulate matter (PM₁₀), the stationary source shall be considered to be exempt for particulate matter. If the emissions of particulate matter (PM₁₀) cannot be determined in a manner acceptable to the board, the emission rate for particulate matter shall be used to determine the exemption status.

E. Exemptions for stationary sources of toxic pollutants not subject to the federal hazardous air pollutant new source review program shall be as follows:

1. Stationary sources exempt from the requirements of Article 5 (9VAC5-60-300 et seq.) of 9VAC5 Chapter 60 as provided in 9VAC5-60-300 C 1, C 2, D or E shall be exempt from the provisions of this article.

2. Facilities as specified below shall not be exempt, regardless of size or emission rate, from the provisions of this article.

a. Incinerators, unless the incinerator is used exclusively as air pollution control equipment.

b. Ethylene oxide sterilizers.

c. Boilers, incinerators, or industrial furnaces as defined in 40 CFR 260.10 and subject to 9VAC20 Chapter 60 (9VAC20-60)

F. Any source category or portion of a source category subject to the federal hazardous air pollutant new source review program shall be exempt from the provisions of this article if specifically exempted from that program by 40 CFR Part 61 or 63.
