9VAC5-50-20. Compliance.
A. Sixty days after achieving the maximum production rate, but not later than 180 days after initial startup, no owner or other person shall operate any new or modified source in violation of any standard of performance prescribed under this chapter.
1. Compliance with standards in this chapter, other than opacity standards, shall be determined by performance tests established by 9VAC5-50-30, unless specified otherwise in the applicable standard.
2. Compliance with federal requirements in this chapter may be determined by alternative or equivalent methods only if approved by the administrator. For purposes of this subsection, federal requirements consist of the following:
a. New source performance standards established pursuant to § 111 of the federal Clean Air Act.
b. All terms and conditions in a federal operating permit, including any provisions that limit a source's potential to emit, unless expressly designated as not federally enforceable.
c. Limitations and conditions that are part of an implementation plan.
d. Limitations and conditions that are part of a section 111(d) or section 111(d)/129 plan.
e. Limitations and conditions that are part of a federal construction permit issued under 40 CFR 52.21 or any construction permit issued under regulations approved by EPA in accordance with 40 CFR Part 51.
f. Limitations and conditions that are part of an operating permit issued pursuant to a program approved by EPA into an implementation plan as meeting EPA's minimum criteria for federal enforceability, including adequate notice and opportunity for EPA and public comment prior to issuance of the final permit and practicable enforceability.
3. Compliance with opacity standards in this chapter may be determined by one or more of the following means:
a. Conducting observations in accordance with Reference Method 9 or any alternative method approved by EPA, if specified in the permit granted pursuant to 9VAC5 Chapter 80 (9VAC5-80). For purposes of determining initial compliance, the minimum total time of observations shall be three hours (30 six-minute averages) for the performance test or other set of observations (meaning those fugitive-type emission sources subject only to an opacity standard). Opacity readings of portions of plumes which contain condensed, uncombined water vapor shall not be used for purposes of determining compliance with opacity standards.
b. Evaluation of data resulting from use of continuous monitoring by transmissometer, provided the instrument used meets Performance Specification 1 in Appendix B of 40 CFR Part 60 and has been properly maintained and that the resulting data have not been altered in any way.
c. Use of any other method approved by EPA.
4. The opacity standards prescribed under this chapter shall apply at all times except during periods of startup, shutdown, malfunction and as otherwise provided in the applicable standard.
5. Variation from a specified standard may be granted by the board for a definite period for testing and adjustment.
B. No owner of a new or modified source subject to the provisions of this chapter shall fail to conduct performance tests as required under this chapter.
C. No owner of a new or modified source subject to the provisions of this chapter shall fail to install, calibrate, maintain and operate equipment for continuously monitoring and recording emissions or process parameters or both as required under this chapter.
D. No owner of a new or modified source subject to the provisions of this chapter shall fail to provide notifications and reports, revise reports, maintain records or report performance test or monitoring results as required under this chapter.
E. At all times, including periods of startup, shutdown, soot blowing and malfunction, owners shall, to the extent practicable, maintain and operate any affected facility including associated air pollution control equipment in a manner consistent with air pollution control practices for minimizing emissions. Determination of whether acceptable operating and maintenance procedures are being used will be based on information available to the board, which may include, but is not limited to, monitoring results, opacity observations, review of operating and maintenance procedures, and inspection of the source.
F. At all times the disposal of volatile organic compounds shall be accomplished by taking measures, to the extent practicable, consistent with air pollution control practices for minimizing emissions. Volatile organic compounds shall not be intentionally spilled, discarded in sewers which are not connected to a treatment plant, or stored in open containers or handled in any other manner that would result in evaporation beyond that consistent with air pollution control practices for minimizing emissions.
G. The following provisions apply with respect to compliance with opacity standards.
1. For the purpose of demonstrating initial compliance, opacity observations shall be conducted concurrently with the initial performance test unless one of the following conditions apply.
a. If no performance test is required, then opacity observations shall be conducted within 60 days after achieving the maximum production rate at which the affected facility will be operated but no later than 180 days after initial startup of the facility.
b. If visibility or other conditions prevent the opacity observations from being conducted concurrently with the initial performance test, the owner shall reschedule the opacity observations as soon after the initial performance test as possible, but not later than 30 days thereafter, and shall advise the board of the rescheduled date. In these cases, the 30-day prior notification to the board required by 9VAC5-50-50 A 6 shall be waived. The rescheduled opacity observations shall be conducted (to the extent possible) under the same operating conditions that existed during the initial performance test. The visible emissions observer shall determine whether visibility or other conditions prevent the opacity observations from being made concurrently with the initial performance test in accordance with procedures contained in Reference Method 9.
Opacity readings of portions of plumes which contain condensed, uncombined water vapor shall not be used for purposes of determining compliance with opacity standards. The owner of an affected facility shall make available, upon request by the board, such records as may be necessary to determine the conditions under which the visual observations were made and shall provide evidence indicating proof of current visible observer emission certification. The results of continuous monitoring by transmissometer which indicate that the opacity at the time visual observations were made was not in excess of the standard are probative but not conclusive evidence of the actual opacity of an emission, provided the source meets the burden of proving that the instrument used meets (at the time of the alleged violation) Performance Specification 1 in Appendix B of 40 CFR Part 60 and has been properly maintained and (at the time of the alleged violation) that the resulting data have not been altered in any way.
2. Except as provided in subdivision 3 of this subsection, the owner of an affected facility to which an opacity standard in this chapter applies shall conduct opacity observations in accordance with subdivision A 3 of this section, shall record the opacity of emissions, and shall report to the board the opacity results along with the results of the initial performance test. The inability of an owner to secure a visible emissions observer shall not be considered a reason for not conducting the opacity observations concurrent with the initial performance test.
3. The owner of an affected facility to which an opacity standard in this chapter applies may request the board to determine and to record the opacity of emissions from the affected facility during the initial performance test and at such times as may be required. The owner of the affected facility shall report the opacity results. Any request to the board to determine and to record the opacity of emissions from an affected facility shall be included in the notification required in 9VAC5-50-50 A 6. If, for some reason, the board cannot determine and record the opacity of emissions from the affected facility during the performance test, then the provisions of subdivision 1 of this subsection shall apply.
4. An owner of an affected facility using a continuous opacity monitor (transmissometer) shall record the monitoring data produced during the initial performance test and shall furnish the board a written report of the monitoring results along with the Reference Method 9 and initial performance test results.
H. The following provisions apply with respect to stack heights.
1. The degree of emission limitation required of any source owner for control of any air pollutant shall not be affected in any manner by:
a. So much of the stack height of any source as exceeds good engineering practice; or
b. Any other dispersion technique.
2. The provisions of subdivision 1 of this subsection shall not apply to:
a. Stack heights in existence, or dispersion techniques implemented on or before December 31, 1970, except where pollutants are being emitted from such stacks or using such dispersion techniques by sources, as defined in § 111(a)(3) of the federal Clean Air Act, which were constructed, or reconstructed, or for which major modifications, as defined in Article 8 (9VAC5-80-1700 et seq.) and Article 9 (9VAC5-80-2000 et seq.) of Part II of 9VAC5 Chapter 80, were carried out after December 31, 1970; or
b. Coal-fired steam electric generating units subject to the provisions of § 118 of the federal Clean Air Act, which commenced operation before July 1, 1957, and whose stacks were constructed under a construction contract awarded before February 8, 1974.
3. Prior to the adoption of a new or revised emission limitation that is based on a good engineering practice stack height that exceeds the height allowed by subdivision 1 or 2 of the GEP definition, the board shall notify the public of the availability of the demonstration study and shall provide opportunity for public hearing on it.
4. For purposes of this subsection, such height shall not exceed the height allowed by subdivision 1 or 2 of the GEP definition unless the owner demonstrates to the satisfaction of the board, after 30 days notice to the public and opportunity for public hearing, that a greater height is necessary as provided under subdivision 3 of the GEP definition.
5. In no event may the board prohibit any increase in any stack height or restrict in any manner the maximum stack height of any source.
6. Compliance with standards of performance in this chapter shall not be affected in any manner by the stack height of any source or any other dispersion technique.
I. For the purpose of submitting compliance certifications or establishing whether or not a person has violated or is in violation of any standard in this chapter, nothing in this chapter shall preclude the use, including the exclusive use, of any credible evidence or information, relevant to whether a source would have been in compliance with applicable requirements if the appropriate performance or compliance test or procedure had been performed.

9VAC5-50-30. Performance testing.
A. Performance tests for new or modified sources shall be conducted and reported and data shall be reduced as set forth in this chapter and the test methods and procedures contained in each applicable subpart listed in 9VAC5-50-410 unless the board (i) specifies or approves, in specific cases, the use of a reference method with minor changes in methodology; (ii) approves the use of an equivalent method; (iii) approves the use of an alternative method the results of which the board has determined to be adequate for indicating whether a specific source is in compliance; (iv) waives the requirement for performance tests because the owner of a source has demonstrated by other means to the board's satisfaction that the affected facility is in compliance with the standard; or (v) approves shorter sampling times and smaller sample volumes when necessitated by process variables or other factors. Any new or modified source, for which no standards of performance are set forth in Article 5 (9VAC5-50-400 et seq.) of this part, shall be performance tested by appropriate reference methods unless the board (i) specifies or approves, in specific cases, the use of a reference method with minor changes in methodology; (ii) approves the use of an equivalent method; (iii) approves the use of an alternative method the results of which the board has determined to be adequate for indicating whether a specific source is in compliance; (iv) waives the requirement for performance tests because the owner of a source has demonstrated by other means to the board's satisfaction that the affected facility is in compliance with the standard; or (v) approves shorter sampling times and smaller sample volumes when necessitated by process variables or other factors. In cases where no appropriate reference method exists for a new or modified source subject to a standard of performance for volatile organic compounds, the test methods in 9VAC5-20-121 may be considered appropriate.
B. Performance testing for new or modified sources shall be subject to testing guidelines approved by the board. Procedures may be adjusted or changed by the board to suit specific sampling conditions or needs based upon good practice, judgment and experience. When such tests are adjusted, consideration shall be given to the effect of such change on established standards. Tests shall be performed under the direction of persons whose qualifications are acceptable to the board.
C. Performance tests for new or modified sources shall be conducted under conditions which the board shall specify to the owner based on representative performance of the source. The owner shall make available to the board such records as may be necessary to determine the conditions of the performance tests. Operation during periods of startup, shutdown and malfunction shall not constitute representative conditions for the purpose of a performance test. During the initial performance test, emissions in excess of the level of the applicable emission limit during periods of startup, shutdown, and malfunction shall not be considered a violation of the applicable emission limit unless otherwise specified in the applicable standard.
D. An owner may request that the board determine the opacity of emissions from a new or modified source during the performance tests required by this section.
E. Unless specified otherwise in the applicable standard, each performance test for a new or modified source shall consist of three separate runs using the applicable test method. Each run shall be conducted for the time and under the conditions specified in the applicable standard. For the purpose of determining compliance with an applicable standard the arithmetic mean of the results of the three runs shall apply. In the event that a sample is accidentally lost or if conditions occur in which one of the three runs must be discontinued because of forced shutdown, failure of an irreplaceable portion of the sample train, extreme meteorological conditions or other circumstances beyond the owner's control, compliance may, upon the approval of the board, be determined using the arithmetic mean of the results of the two other runs.
F. The board may test emissions of air pollutants from any new or modified source. Upon request of the board the owner shall provide, or cause to be provided, performance testing facilities as follows:
1. Sampling ports adequate for test methods applicable to such source. This includes (i) constructing the air pollution control system such that volumetric flow rates and pollutant emission rates can be accurately determined by applicable test methods and procedures and (ii) providing a stack or duct with acceptable flow characteristics during performance tests, as demonstrated by applicable test methods and procedures.
2. Safe sampling platforms.
3. Safe access to sampling platforms.
4. Utilities for sampling and testing equipment.
G. Upon request of the board, the owner of any new or modified source subject to the provisions of this chapter shall conduct performance tests in accordance with procedures approved by the board.

7. Alternatives to the ASTM test methods or sampling procedures specified by any subpart listed in 9VAC5-50-410.
8. Alternative continuous monitoring systems that do not meet the design or performance requirements in Performance Specification 1 of Appendix B of 40 CFR Part 60, but adequately demonstrate a definite and consistent relationship between its measurements and the measurements of opacity by a system complying with the requirements in Performance Specification 1 of Appendix B of 40 CFR Part 60. The board may require that demonstration be performed for each affected facility.
9. Alternative monitoring requirements when the effluent from a single affected facility or the combined effluent from two or more affected facilities are released to the atmosphere through more than one point.
10. Alternative monitoring systems that meet the requirements of 40 CFR Part 75 (i) if a source is subject to 40 CFR Part 75 or (ii) if the board determines that the requirements of 40 CFR Part 75 are more appropriate for the source than the pertinent provisions of this chapter.
F. Upon request of the board, the owner of a new or modified source subject to the provisions of this chapter shall install, calibrate, maintain and operate equipment for continuously monitoring and recording emissions or process parameters or both in accordance with methods and procedures acceptable to the board.

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 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.

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 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 for which there would be an uncontrolled emission rate equal to or greater than the levels in 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 project shall apply best available control technology for each regulated pollutant for which 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 affected emissions 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 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 BACT determination for the affected emissions units.

9VAC5-50-405. Authority to implement and enforce standards as authorized by EPA.
A. This article provides the legally enforceable mechanism to facilitate the Commonwealth's obligation to implement and enforce the federal NSPSs as state requirements.
B. The Commonwealth's delegated authority to implement and enforce the standards designated in 9VAC5-50-410 as authorized by EPA is identified in the documents specified in subdivisions 1 through 5 of this subsection. The Commonwealth's delegated authority extends only to the source categories and pollutants identified in the documents and is subject to the provisions, conditions, and limitations set forth in the following documents:
1. Letter from Daniel J. Snyder dated December 30, 1975.
2. Federal Register notice dated February 26, 1976 (41 FR 8416).
3. Letter from Thomas C. Voltaggio dated July 22, 1981.
4. Federal Register notice dated August 27, 1981 (46 FR 43300).
5. Letter from W. Ray Cunningham dated July 2, 1985.
C. In its delegation notices and letters, EPA automatically delegated to the Commonwealth the authority to implement and enforce future NSPS requirements if the Commonwealth legally adopted the requirements, informed EPA that it intended to enforce the standards in accordance with the terms of the delegation, and met other conditions. The latest letter that the Commonwealth submitted to obtain authority to implement and enforce additional requirements is available for examination as provided in subsection D of this section.
D. Copies of the documents cited in subsections B and C of this section may be examined by the public at the central office of the Department of Environmental Quality, 1111 East Main Street, Suite 1400, Richmond, Virginia between 8:30 a.m. and 4:30 p.m. of each business day.
E. The documents cited in subsection B of this section establish the terms of the delegation to the Commonwealth to implement and enforce the federal NSPSs as authorized by EPA. As such, the documents place requirements upon the Commonwealth, not the affected facilities; thus the documents are not being incorporated by reference into the regulations of the board but are being cited for information purposes only.
