Article 4
Standards of Performance for Stationary Sources (Rule 5-4)

9VAC5-50-240. Applicability and designation of affected facility.

A. The affected facilities in at stationary sources to which the provisions of this article apply are facilities emissions units that emit or cause air pollution are subject to the new source review program.

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

C. The provisions of this article apply only to affected facilities subject to the new source review program to any regulated air pollutant except to the extent that it is regulated under 9VAC5-60 (Hazardous Air Pollutant Sources). However, the exemption provided by this subsection does not extend to other properties of the exempted pollutants that may require regulation under 9VAC5-40 (Existing Stationary Sources) or 9VAC5-50 (New and Modified Stationary Sources).

9VAC5-50-250. Definitions.

A. For the purpose of applying this article in the context of the Regulations for the Control and Abatement of Air Pollution and subsequent amendments or any orders issued by the board related uses, the words or terms shall have the meanings given them in subsection C of this section.

B. As used in this article Unless otherwise required by context, all terms not defined here herein shall have the meanings given them in 9VAC5 Chapter 10 (9VAC5-10-), unless otherwise required by context 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, a standard of performance an emissions limitation (including a visible emission standard) based on the maximum degree of emission reduction for any pollutant which would be emitted from any proposed 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 such source 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 Chapter 60 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 Chapter 80, consideration shall be given to the nature and amount of the new emissions, emission control efficiencies achieved in the industry for the source type, and the cost effectiveness of the incremental emission reduction achieved.

"Lowest achievable emission rate" means for any source, the more stringent rate of emissions based on the following:

1. The most stringent emissions limitation which is contained in the implementation plan of any state for such class or category of stationary source, unless the owner of the proposed stationary source demonstrates that such limitations are not achievable; or

2. The most stringent emissions limitation which is achieved in practice by such class or category of stationary source. This limitation, when applied to a modification, means the lowest achievable emissions rate for the new or modified emissions units within the stationary source. In no event shall the application of this term permit a proposed new or modified stationary source to emit any pollutant in excess of the amount allowable under an applicable new source standard of performance.

"New source review (NSR) program" means a preconstruction review and permit program (i) for new stationary sources or modifications (physical changes or changes in the method of operation); (ii) established to implement the requirements of §§ 110(a)(2)(C), 112 (relating to permits for hazardous air pollutants), 165 (relating to permits in prevention of significant deterioration areas), and 173 (relating to permits in nonattainment areas) of the federal Clean Air Act and associated regulations; and (iii) codified in Article 6 (9VAC5-80-1100 et seq.), Article 7 (9VAC5-80-1400 et seq.), Article 8 (9VAC5-80-1605 et seq.) and Article 9 (9VAC5-80-2000 et seq.) of 9VAC5 Chapter 80.

9VAC5-50-260. Standard for stationary sources.

A. No owner or other person shall cause or permit to be discharged into the atmosphere from any affected facility any emissions in excess of that resultant from using emissions limitations representing best available control technology, as reflected in any term or condition that may be placed upon the minor NSR permit approval for the facility.

B. A new stationary source shall apply best available control technology for each regulated pollutant that it would have the potential to emit in amounts for which there would be an uncontrolled emission rate equal to or greater than the levels in 9VAC5-80-1320 C 9VAC5-80-1105 C. For a new stationary source, a permit may be issued pursuant to Article 6 (9VAC5-80-1100 et seq.) of Part II of 9VAC5-80 (Permits for Stationary Sources) containing such terms and conditions as may be necessary to implement a best available control technology determination for any regulated air pollutant that may be emitted from any affected emissions unit.

C. A modification project shall apply best available control technology for each regulated pollutant for which it would result in a net emissions increase at the source there would be an increase in the uncontrolled emission rate equal to or greater than the levels in 9VAC5-80-1105 D. This requirement applies to each proposed affected emissions unit at which a net emissions increase in the pollutant would occur in amounts equal to or greater than the levels in 9VAC5-80-1320 D as a result of physical change or change in the method of operation in the unit in the project. For a project, a permit may be issued pursuant to Article 6 (9VAC5-80-1100 et seq.) of Part II of 9VAC5-80 (Permits for Stationary Sources) containing such terms and conditions as may be necessary to implement a best available control technology determination for any regulated air pollutant emitted, or that may be emitted, from any affected emissions unit.

D. For the phased construction of new stationary sources or projects, the determination of best available control technology BACT determination shall be reviewed and modified, as appropriate, at the latest reasonable time which occurs no later than 18 months prior to commencement of construction of each independent phase of the new stationary source or project. At such time, the owner of the applicable stationary source or project may be required to demonstrate the adequacy of any previous determination of best available control technology BACT determination for the source affected emissions units.

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.

E. Where construction of a new stationary source or a project is accomplished in contemporaneous increments that individually are not subject to approval under this article and that are not part of a program of construction of a new stationary source or project in planned incremental phases approved by the board, all such increments shall be added together for determining the applicability of any particular change under the provisions of this article. An incremental change is contemporaneous with the particular change only if it occurs between the date five years before commencing construction on the particular change and the date that the emissions increase from the particular change occurs.

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 stationary source which, except for the pattern of ownership or development, would otherwise require a minor NSR 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, relocation, replacement, 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.

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 minor NSR permit designated state-only enforceable under 9VAC5-80-1120 F.

I. For sources subject to the federal hazardous air pollutant new source review program, the provisions of the federal hazardous air pollutant new source review program shall be implemented through this article and the applicable article of Part II of 9VAC5-60 (Hazardous Air Pollutant Sources). Implementation of the federal hazardous air pollutant new source review program shall be independent of applicability and exemption criteria of this article. Additional details may be found in subdivisions 1, 2, and 3 of this subsection. Minor NSR permits shall be the administrative mechanism for issuing approvals under the provisions of federal hazardous air pollutant new source review program. Except as noted below, in cases where there are differences between the provisions of this article and the provisions of federal hazardous air pollutant new source review program, the more restrictive provisions shall apply. The provisions of 9VAC5-80-1150 and 9VAC5-80-1160 shall not apply to sources subject to the federal hazardous air pollutant new source review program. Other sections of this article also provide requirements relative to the application of this article to sources subject to the federal hazardous air pollutant new source review program, in which case those provisions shall prevail.

9VAC5-80-1105. Permit exemptions.

A. The general requirements for minor NSR permit exemptions are as follows:

1. The provisions of this article do not apply to the following stationary sources or emissions units:

a. The construction of any stationary source or emissions unit that is exempt under the provisions of subsections B through F of this section. In determining whether a source is exempt from the provisions of this article, the provisions of subsections B through D of this section are independent from the provisions of subsections E and F of this section. A source must be determined to be exempt both under the provisions of subsections B through D of this section taken as a group and under the provisions of subsections E and F of this section to be exempt from this article.

b. Vegetative waste recycling/mulching operations that do not exceed 2100 hours of operation in any 12-month consecutive period at a single stationary source. To qualify as an exemption under this subdivision, the total rated capacity of all diesel engines at the source, including portable diesel engines temporarily located at the site, may not exceed 1200 brake horsepower (output).

c. The location of a portable emissions unit at a site subject to the following conditions:

d. The reactivation of a stationary source unless a determination concerning shutdown has been made pursuant to the provisions of 9VAC5-20-220.

e. The use by any existing stationary source or emissions unit of an alternative fuel or raw material, if the following conditions are met:

(1) The owner demonstrates to the board that, as a result of trial burns at the owner's facility or other facilities or other sufficient data, the emissions resulting from the use of the alternative fuel or raw material supply are decreased. No demonstration will be required for the use of processed animal fat, processed fish oil, processed vegetable oil, distillate oil, or any mixture thereof in place of the same quantity of residual oil to fire industrial boilers.

(2) The use of an alternative fuel or raw material would not be subject to review under this article as a project.

2. The provisions of this article do not apply to the following stationary sources or emissions units provided the stationary source or emissions unit is (i) exempt under the provisions of subsections E and F of this section and (ii) meets any other applicable criteria or conditions set forth in this subdivision.

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

1. New stationary sources with uncontrolled emission rates less than all of the emission rates specified below shall be exempt from the provisions of this article. The uncontrolled emission rate of a new stationary source is the sum of the uncontrolled emission rates of the individual affected emissions units. Facilities exempted by subsection B of this section shall not be included in the summation of uncontrolled emissions for purposes of exempting new stationary sources under this subsection.

2. If the particulate matter (PM₁₀ or PM_2.5) 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 or PM_2.5), the stationary source shall be considered to be exempt for particulate matter (PM). If the emissions of particulate matter (PM₁₀ or PM_2.5) cannot be determined in a manner acceptable to the board, the emission rate for particulate matter (PM) shall be used to determine the exemption status.

3. The provisions of this article do not apply to a new stationary source if all of the emissions considered in calculating the uncontrolled emission rate of the new stationary source are fugitive emissions.

D. The exemption of projects shall be determined as specified below:

1. A project that would result in increases in uncontrolled emission rates at the stationary source less than all of the emission rates specified below shall be exempt from the provisions of this article. The uncontrolled emission rate increase of a project is the sum of the uncontrolled emission rate increases of the individual affected emissions units. Uncontrolled emissions rate decreases are not considered as part of this calculation. Facilities exempted by subsection B of this section shall not be included in the summation of uncontrolled emissions for purposes of exempting projects under this subsection.

2. If the particulate matter (PM₁₀ or PM_2.5) 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 or PM_2.5), the stationary source shall be considered to be exempt for particulate matter (PM). If the emissions of particulate matter (PM₁₀ or PM_2.5) cannot be determined in a manner acceptable to the board, the emission rate for particulate matter (PM) shall be used to determine the exemption status.

3. The provisions of this article do not apply to a project if all of the emissions considered in calculating the uncontrolled emission rate increase of the project are fugitive emissions.

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 Part II of 9VAC5-60 (Hazardous Air Pollutant Sources) as provided in 9VAC5-60-300 C 1, C 2, C 7, D, or E shall be exempt from the provisions of this article.

"State enforceable" means all limitations and conditions which that 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" means a permit issued under the state operating permit program.

"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 that emits or may emit any regulated air pollutant. A stationary source shall include all of the pollutant-emitting activities which that 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 that 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 source" 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 that otherwise has the potential to emit regulated air pollutants in amounts that are at or above those for major stationary sources, as applicable, but that has taken a restriction so that its potential to emit is less than such amounts for major stationary sources. Such restrictions must be enforceable as a practical matter. The term "synthetic minor source" applies independently for each regulated air pollutant that the source has the potential to emit.

"Temporary facility" means a facility that (i) is operated to achieve a specific objective (such as serving as a pilot test facility, a process feasibility project, or a remediation project) and (ii) does not contribute toward the commercial production of any product or service (including byproduct and intermediate product) during the operational period. Portable emissions units covered by the exemption under 9VAC5-80-1105 A 1 c and facilities used to augment or enable routine production are not considered temporary facilities for the purposes of this definition.

"Toxic pollutant" means any air pollutant (i) listed in § 112(b) of the federal Clean Air Act, as amended by Subpart C of 40 CFR Part 63 and (ii) incorporated by reference into the regulations of the board at 9VAC5-60-92 B, or any other air pollutant that the board determines, through adoption of regulation, to present a significant risk to public health. This term excludes asbestos, fine mineral fibers, radionuclides, and any glycol ether that does not have a TLV®.

"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.

"Undeveloped site" means any site or facility at which no emissions units are located at the time the permit application is deemed complete, or at the time the owner begins actual construction, whichever occurs first. An undeveloped site also includes any site or facility at which all of the emissions units have been determined to be shut down pursuant to the provisions of 9VAC5-20-220.

"Vegetative waste" means decomposable materials generated by land clearing activities and includes shrub, bush and tree prunings, bark, brush, leaves, limbs, roots, and stumps. Vegetative waste does not include construction or demolition waste or any combination of them.

"Vegetative waste recycling/mulching operation" means any activity related to size reduction or separating, or both, of clean wood or vegetative waste, or both, by grinding, shredding, chipping, screening, or any combination of them.

9VAC5-80-1120. General.

A. No owner or other person shall begin actual construction, reconstruction or modification of, or operate, any new stationary source or any project subject to this article without first obtaining from the board a permit to construct and operate or to modify and operate the source under the provisions of this article. The owner may not construct or operate the stationary source or project contrary to the terms and conditions of that permit.

B. Except as provided in 9VAC5-80-1320 9VAC5-80-1105 A 1 c, no owner or other person shall relocate any stationary source or emissions unit from one stationary source to another without first obtaining from the board a minor NSR permit to relocate the stationary source or unit.

C. No Except as provided in 9VAC5-80-1105 A 2 b, no owner or other person shall reduce the outlet elevation of any stack or chimney which discharges any regulated air pollutant from an affected facility emissions unit without first obtaining a minor NSR permit from the board.

D. The board may combine the requirements of and the permits for emissions units within a stationary source subject to the new source review program into one permit. Likewise the board may require that applications for permits for emissions units within a stationary source required by any provision of the new source review program be combined into one application. The board will take actions to combine permit terms and conditions as provided in 9VAC5-80-1255. Actions to combine permit terms and conditions involve relocating the terms and conditions contained in two or more permits issued to single stationary source to a single permit document. Actions to combine permit terms and conditions in and of themselves are not a mechanism for making changes to permits; such actions shall be taken under 9VAC5-80-1260 as explained in subsection E of this section.

E. The board may incorporate the terms and conditions of a state operating permit into a permit issued pursuant to this article. The permit issued pursuant to this article may supersede the state operating permit provided the public participation provisions of the state operating permit program are followed. The board may incorporate the terms and conditions of a permit issued pursuant to this article into a state operating permit provided all of the permitted emissions units are operational and determined to be in compliance in accordance with 9VAC5-80-1200. The board will take actions to make changes to permit terms and conditions as provided in 9VAC5-80-1260. Nothing in this subsection is intended to imply that once an action has been taken to make a change to a permit, the resulting permit change may not be combined with other terms and conditions in a single permit document as provided in subsection D of this section.

F. All terms and conditions of any minor NSR permit issued under this article shall be federally enforceable except those that are designated state-only enforceable under subdivision 1 of this subsection. Any term or condition that is not federally enforceable shall be designated as state-only enforceable as provided in subdivision 2 of this subsection.

1. A term or condition of any minor NSR permit issued under this article shall not be federally enforceable if it is derived from or is designed to implement Article 2 (9VAC5-40-130 et seq.) of 9VAC5 Chapter 40 Part II of 9VAC5-40 (Existing Stationary Sources), Article 2 (9VAC5-50-130 et seq.) of 9VAC5 Chapter 50 Part II of 9VAC5-50 (New and Modified Stationary Sources), or Article 4 (9VAC5-60-200 et seq.) or Article 5 (9VAC5-60-300 et seq.) of 9VAC5 Chapter 60 Part II of 9VAC5-60 (Hazardous Air Pollutant Sources).

2. Any term or condition of any minor NSR permit issued under this article that is not federally enforceable shall be marked in the permit as state-only enforceable and shall only be enforceable only by the board. Incorrectly designating a term or condition as state-only enforceable shall not provide a shield from federal enforcement of a term or condition that is legally federally enforceable.

G. Nothing in the regulations of the board shall be construed to prevent the board from granting minor NSR permits for programs of construction or modification of a new stationary source or project in planned incremental phases. In such cases, all net emissions increases from all emissions units covered by the program shall be added together for determining the applicability of this article.

H. For sources subject to the federal hazardous air pollutant new source review program, the provisions of the federal hazardous air pollutant new source review program shall be implemented through this article and the applicable article of 9VAC5 Chapter 60 (9VAC5-60). Permits issued under this article shall be the administrative mechanism for issuing approvals under the provisions of federal hazardous air pollutant new source review program. Except as noted below, in cases where there are differences between the provisions of this article and the provisions of federal hazardous air pollutant new source review program, the more restrictive provisions shall apply. The provisions of 9VAC5-80-1150 and 9VAC5-80-1160 shall not apply to sources subject to the federal hazardous air pollutant new source review program. Other sections of this article also provide requirements relative to the application of this article to sources subject to the federal hazardous air pollutant new source review program, in which case those provisions shall prevail. This subsection applies only to the extent that the provisions of the federal hazardous air pollutant new source review program are not being implemented by other new source review program regulations of the board.

9VAC5-80-1140. Applications.

A. A single application is required identifying at a minimum each emissions unit subject to the provisions of this article in the new stationary source or the project, or affected by the stack outlet elevation reduction. The application shall be submitted according to procedures acceptable to the board. However, where several emissions units are included in one project, a single application covering all units in the project may be submitted.

B. A separate application is required for each new stationary source or project.

C. For new stationary sources or for projects with phased development, a single application should be submitted covering the entire new stationary source or project.

D. Any application, form, report, or certification submitted to the board shall comply with the provisions of 9VAC5-20-230.

E. Any application submitted pursuant to this article shall contain a certification signed by the applicant as follows:

"I certify that I understand that the existence of a minor new source review permit under this article does not shield the source from potential enforcement of any regulation of the board governing the major new source review program and does not relieve the source of the responsibility to comply with any applicable provision of the major NSR new source review program regulations."

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 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.
