Action:
Amendments to Implement the 2012 PM2.5 Standard
Stage: Final
 
9VAC5-30-65

9VAC5-30-65. Particulate matter (PM2.5).

A. The primary and secondary ambient air quality standards for particulate matter are:

1. 15.0 micrograms per cubic meter -- annual arithmetic mean concentration.

2. 65 micrograms per cubic meter -- 24-hour average concentration.

B. Particulate matter shall be measured in the ambient air as PM2.5 (particles with an aerodynamic diameter less than or equal to a nominal 2.5 micrometers) by a reference method based on Appendix L of 40 CFR Part 50, or other method designated as such, or by an equivalent method.

C. The annual primary and secondary PM2.5 standards are met when the annual arithmetic mean concentration, as determined in accordance with Appendix N of 40 CFR Part 50, is less than or equal to 15.0 micrograms per cubic meter.

D. The 24-hour primary and secondary PM2.5 standards are met when the 98th percentile 24-hour concentration, as determined in accordance with Appendix N of 40 CFR Part 50, is less than or equal to 65 micrograms per cubic meter.

E. The PM2.5 standards set forth in this section were established by EPA on July 18, 1997 (62 FR 38652) and became effective on September 8, 2004, by adoption by the board. The PM2.5 standards set forth in this section shall continue to apply only for purposes of the following:

1. Control strategy implementation plan revisions, maintenance plans, and associated emissions budgets relative to the PM2.5 standards in this section.

2. Designation of nonattainment areas and maintenance areas relative to the PM2.5 standards in this section.

Nothing in this section shall prevent the redesignation of any nonattainment area to attainment at any time.

F. The primary annual standard set forth in subsection A of this section shall no longer apply as of October 24, 2016. The secondary annual standard and the 24-hour standard set forth in subsection A of this section shall remain in effect.

9VAC5-80-2000

Article 9
Permits for Major Stationary Sources and Major Modifications Locating in Nonattainment Areas or the Ozone Transport Region

9VAC5-80-2000. Applicability.

A. The provisions of this article apply to the construction of any new major stationary source or a major modification that is major for the pollutant for which the area is designated as nonattainment. Different pollutants, including individual precursors, are not summed to determine applicability of a major stationary source or major modification.

B. The provisions of this article apply in (i) nonattainment areas designated in 9VAC5-20-204 or (ii) the Ozone Transport Region as defined in 9VAC5-80-2010 C. This article applies to all localities in the Ozone Transport Region regardless of a locality's nonattainment status.

C. If the Ozone Transport Region is designated attainment for ozone, sources located or planning to locate in the region shall be subject to the offset requirements for areas classified as moderate in 9VAC5-80-2120 B 2. If the Ozone Transport Region is designated nonattainment for ozone, sources located or planning to locate in the region shall be subject to the offset requirements of 9VAC5-80-2120 B depending on the classification except if the classification is marginal or there is no classification, the classification shall be moderate for purpose of applying 9VAC5-80-2120 B.

D. At such time that a particular source or modification becomes a major stationary source or major modification solely by virtue of a relaxation in any enforceable limitation which was established after August 7, 1980, on the capacity of the source or modification otherwise to emit a pollutant, such as a restriction on hours of operation, then the requirements of this article shall apply to the source or modification as though construction had not commenced on the source or modification.

E. Unless specified otherwise, the provisions of this article apply as follows:

1. Provisions referring to "sources," "new and/or modified sources" or "stationary sources" apply to the construction of all major stationary sources and major modifications.

2. Any emissions units or pollutants not subject to the provisions of this article may be subject to the provisions of Article 6 (9VAC5-80-1100 et seq.), Article 7 (9VAC5-80-1400 et seq.), or Article 8 (9VAC5-80-1605 et seq.) of this part.

3. Provisions referring to "state and federally enforceable" and "federally and state enforceable" or similar wording shall mean "state-only enforceable" for terms and conditions of a permit designated state-only enforceable under 9VAC5-80-2020 E.

F. Unless otherwise approved by the board or prescribed in these regulations, when this article is amended, the previous provisions of this article shall remain in effect for all applications that are deemed complete under the provisions of 9VAC5-80-2060 A prior to September 1, 2006. Any permit applications that have not been determined to be complete as of September 1, 2006, shall be subject to the new provisions.

G. 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.

H. The requirements of this article will be applied in accordance with the following principles:

1. Except as otherwise provided in subsection I of this section, and consistent with the definition of "major modification," a project is a major modification for a regulated NSR pollutant if it causes two types of emissions increases: (i) a significant emissions increase and (ii) a significant net emissions increase. A project is not a major modification if it does not cause a significant emissions increase. If a project causes a significant emissions increase, then the project is a major modification only if it also results in a significant net emissions increase.

2. The procedure for calculating (before beginning actual construction) whether a significant emissions increase (i.e., the first step of the process) will occur depends upon the type of emissions units being modified, according to subdivisions 3 and 4 of this subsection. The procedure for calculating (before beginning actual construction) whether a significant net emissions increase will occur at the source (i.e., the second step of the process) is contained in the definition of "net emissions increase." Regardless of any such preconstruction projections, a major modification results if the project causes a significant emissions increase and a significant net emissions increase.

3. The actual-to-projected-actual applicability test for projects that only involve existing emissions units shall be as provided in this subdivision. A significant emissions increase of a regulated NSR pollutant is projected to occur if the sum of the difference between the projected actual emissions and the baseline actual emissions for each existing emissions unit, equals or exceeds the significant amount for that pollutant.

4. The actual-to-potential test for projects that only involve construction of a new emissions unit shall be as provided in this subdivision. A significant emissions increase of a regulated NSR pollutant is projected to occur if the sum of the difference between the potential to emit from each new emissions unit following completion of the project and the baseline actual emissions of these units before the project equals or exceeds the significant amount for that pollutant.

5. The hybrid test for projects that involve multiple types of emissions units shall be as provided in this subdivision. A significant emissions increase of a regulated NSR pollutant is projected to occur if the sum of the emissions increases for each emissions unit, using the method specified in subdivisions 3 and 4 of this subsection as applicable with respect to each emissions unit, for each type of emissions unit is significant for that pollutant. For example, if a project involves both an existing emissions unit and a new unit, the projected increase is determined by summing the values determined using the method specified in subdivision 3 of this subsection for the existing unit and using the method specified in subdivision 4 of this subsection for the new unit.

I. For any major stationary source for a PAL for a regulated NSR pollutant, the major stationary source shall comply with the requirements under 9VAC5-80-2144.

J. The provisions of 40 CFR Part 60, Part 61 and Part 63 cited in this article apply only to the extent that they are incorporated by reference in Article 5 (9VAC5-50-400 et seq.) of Part II of 9VAC5 Chapter 50 and Article 1 (9VAC5-60-60 et seq.) and Article 2 (9VAC5-60-90 et seq.) of Part II of 9VAC5 Chapter 60.

K. The provisions of 40 CFR Part 51 and Part 58 cited in this article apply only to the extent that they are incorporated by reference in 9VAC5-20-21.

9VAC5-80-2010

9VAC5-80-2010. Definitions.

A. As used in this article, all words or terms not defined here shall have the meanings given them in 9VAC5-10 (General Definitions), unless otherwise required by context.

B. For the purpose of this article, 9VAC5-50-270, and any related use, the words or terms shall have the meanings given them in subsection C of this section.

C. Terms defined.

"Actual emissions" means the actual rate of emissions of a regulated NSR pollutant from an emissions unit, as determined in accordance with subdivisions a, b, and c of this definition, except that this definition shall not apply for calculating whether a significant emissions increase has occurred, or for establishing a PAL under 9VAC5-80-2144. Instead, the definitions of "projected actual emissions" and "baseline actual emissions" shall apply for those purposes.

a. 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 consecutive 24-month period which precedes the particular date and which 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.

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

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

"Actuals PAL for a major stationary source" means a PAL based on the baseline actual emissions of all emissions units at the source that emit or have the potential to emit the PAL pollutant.

"Administrator" means the administrator of the U.S. Environmental Protection Agency (EPA) or an authorized representative.

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

a. The applicable standards set forth in 40 CFR Parts 60, 61 and 63;

b. Any applicable implementation plan emissions limitation including those with a future compliance date; or

c. The emissions limit specified as a federally and state enforceable permit condition, including those with a future compliance date.

For the purposes of actuals PALs, "allowable emissions" shall also be calculated considering any emission limitations that are enforceable as a practical matter on the emissions unit's potential to emit.

"Applicable federal requirement" means all of, but not limited to, the following as they apply to emissions units in a source subject to this article (including requirements that have been promulgated or approved by the administrator through rulemaking at the time of permit issuance but have future-effective compliance dates):

a. Any standard or other requirement provided for in an implementation plan established pursuant to § 110 or 111(d) of the federal Clean Air Act, including any source-specific provisions such as consent agreements or orders.

b. Any limit or condition in any construction permit issued under the new source review program or in any operating permit issued pursuant to the state operating permit program.

c. Any emission standard, alternative emission standard, alternative emission limitation, equivalent emission limitation, or other requirement established pursuant to § 112 or 129 of the federal Clean Air Act as amended in 1990.

d. Any new source performance standard or other requirement established pursuant to § 111 of the federal Clean Air Act, and any emission standard or other requirement established pursuant to § 112 of the federal Clean Air Act before it was amended in 1990.

e. Any limitations and conditions or other requirement in a Virginia regulation or program that has been approved by EPA under subpart E of 40 CFR Part 63 for the purposes of implementing and enforcing § 112 of the federal Clean Air Act.

f. Any requirement concerning accident prevention under § 112(r)(7) of the federal Clean Air Act.

g. Any compliance monitoring requirements established pursuant to either § 504(b) or 114(a)(3) of the federal Clean Air Act.

h. Any standard or other requirement for consumer and commercial products under § 183(e) of the federal Clean Air Act.

i. Any standard or other requirement for tank vessels under § 183(f) of the federal Clean Air Act.

j. Any standard or other requirement in 40 CFR Part 55 to control air pollution from outer continental shelf sources.

k. Any standard or other requirement of the regulations promulgated to protect stratospheric ozone under Title VI of the federal Clean Air Act, unless the administrator has determined that such requirements need not be contained in a permit issued under this article.

l. With regard to temporary sources subject to 9VAC5-80-130, (i) any ambient air quality standard, except applicable state requirements, and (ii) requirements regarding increments or visibility as provided in Article 8 (9VAC5-80-1605 et seq.) of this part.

"Baseline actual emissions" means the rate of emissions, in tons per year, of a regulated NSR pollutant, as determined in accordance with the following:

a. For any existing electric utility steam generating unit, baseline actual emissions means the average rate, in tons per year, at which the unit actually emitted the pollutant during any consecutive 24-month period selected by the owner within the five-year period immediately preceding when the owner begins actual construction of the project. The board may allow the use of a different time period upon a determination that it is more representative of normal source operation.

(1) The average rate shall include fugitive emissions to the extent quantifiable, and emissions associated with startups, shutdowns, and malfunctions.

(2) The average rate shall be adjusted downward to exclude any noncompliant emissions that occurred while the source was operating above any emission limitation that was legally enforceable during the consecutive 24-month period.

(3) For a regulated NSR pollutant, when a project involves multiple emissions units, only one consecutive 24-month period shall be used to determine the baseline actual emissions for the emissions units being changed. A different consecutive 24-month period may be used for each regulated NSR pollutant.

(4) The average rate shall not be based on any consecutive 24-month period for which there is inadequate information for determining annual emissions, in tons per year, and for adjusting this amount if required by subdivision a (2) of this definition.

b. For an existing emissions unit other than an electric utility steam generating unit, baseline actual emissions means the average rate, in tons per year, at which the emissions unit actually emitted the pollutant during any consecutive 24-month period selected by the owner within the 10-year period immediately preceding either the date the owner begins actual construction of the project, or the date a complete permit application is received by the board for a permit required either under this section or under a plan approved by the administrator, whichever is earlier, except that the 10-year period shall not include any period earlier than November 15, 1990. The board will allow the use of a different time period upon a determination that it is more representative of normal source operation.

(1) The average rate shall include fugitive emissions to the extent quantifiable, and emissions associated with startups, shutdowns, and malfunctions.

(2) The average rate shall be adjusted downward to exclude any noncompliant emissions that occurred while the source was operating above any emission limitation that was legally enforceable during the consecutive 24-month period.

(3) The average rate shall be adjusted downward to exclude any emissions that would have exceeded an emission limitation with which the source shall currently comply, had such source been required to comply with such limitations during the consecutive 24-month period. However, if an emission limitation is part of a maximum achievable control technology standard that the administrator proposed or promulgated under 40 CFR Part 63, the baseline actual emissions need only be adjusted if the state has taken credit for such emissions reductions in an attainment demonstration or maintenance plan consistent with the requirements of 9VAC5-80-2120 K.

(4) For a regulated NSR pollutant, when a project involves multiple emissions units, only one consecutive 24-month period shall be used to determine the baseline actual emissions for the emissions units being changed. A different consecutive 24-month period may be used for each regulated NSR pollutant.

(5) The average rate shall not be based on any consecutive 24-month period for which there is inadequate information for determining annual emissions, in tons per year, and for adjusting this amount if required by subdivisions b (2) and b (3) of this definition.

c. For a new emissions unit, the baseline actual emissions for purposes of determining the emissions increase that will result from the initial construction and operation of such unit shall equal zero; and thereafter, for all other purposes, shall equal the unit's potential to emit.

d. For a PAL for a major stationary source, the baseline actual emissions shall be calculated for existing electric utility steam generating units in accordance with the procedures contained in subdivision a of this definition, for other existing emissions units in accordance with the procedures contained in subdivision b of this definition, and for a new emissions unit in accordance with the procedures contained in subdivision c of this definition.

"Begin actual construction" means, in general, initiation of physical on-site construction activities on an emissions unit that are of a permanent nature. Such activities include, but are not limited to, installation of building supports and foundations, laying of underground pipework, and construction of permanent storage structures. With respect to a change in method of operation, this term refers to those on-site activities other than preparatory activities which mark the initiation of the change.

"Best available control technology" or "BACT" means an emissions limitation (including a visible emissions standard) based on the maximum degree of reduction for each regulated NSR pollutant that would be emitted from any proposed major stationary source or major modification that 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 or modification through 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 that would exceed the emissions allowed by any applicable standard under 40 CFR Parts 60, 61, and 63. 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 emissions standard infeasible, a design, equipment, work practice, operational standard, or combination thereof, may be prescribed instead to satisfy the requirement for the application of best available control technology. Such standard shall, to the degree possible, set forth the emissions reduction achievable by implementation of such design, equipment, work practice or operation, and shall provide for compliance by means that achieve equivalent results.

"Building, structure, facility, or installation" means all of the pollutant-emitting activities 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 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," as amended by the supplement (see 9VAC5-20-21).

"Clean coal technology" means any technology, including technologies applied at the precombustion, combustion, or post-combustion stage, at a new or existing facility that will achieve significant reductions in air emissions of sulfur dioxide or nitrogen oxides associated with the utilization of coal in the generation of electricity, or process steam that was not in widespread use as of November 15, 1990.

"Clean coal technology demonstration project" means a project using funds appropriated under the heading "Department of Energy-Clean Coal Technology," up to a total amount of $2,500,000,000 $2.5 billion for commercial demonstration of clean coal technology, or similar projects funded through appropriations for the U.S. EPA. The federal contribution for a qualifying project shall be at least 20% of the total cost of the demonstration project.

"Commence," as applied to construction of a major stationary source or major modification, means that the owner has all necessary preconstruction approvals or permits and either has:

a. Begun, or caused to begin, a continuous program of actual on-site construction of the source, to be completed within a reasonable time; or

b. Entered into binding agreements or contractual obligations, which cannot be canceled or modified without substantial loss to the owner, to undertake a program of actual construction of the source, to be completed within a reasonable time.

"Complete application" means that the application contains all the information necessary for processing the application and the provisions of § 10.1-1321.1 of the Virginia Air Pollution Control Law have been met. Designating an application complete for purposes of permit processing does not preclude the board from requesting or accepting additional information.

"Construction" means any physical change in or change in the method of operation (including fabrication, erection, installation, demolition, or modification of an emissions unit) that would result in a change in actual emissions.

"Continuous emissions monitoring system" or "CEMS" means all of the equipment that may be required to meet the data acquisition and availability requirements of this article, to sample, condition (if applicable), analyze, and provide a record of emissions on a continuous basis.

"Continuous emissions rate monitoring system" or "CERMS" means the total equipment required for the determination and recording of the pollutant mass emissions rate (in terms of mass per unit of time).

"Continuous parameter monitoring system" or "CPMS" means all of the equipment necessary to meet the data acquisition and availability requirements of this article, to monitor process and control device operational parameters (for example, control device secondary voltages and electric currents) and other information (for example, gas flow rate, O2 or CO2 concentrations), and to record average operational parameter values on a continuous basis.

"Electric utility steam generating unit" means any steam electric generating unit that is constructed for the purpose of supplying more than one-third of its potential electric output capacity and more than 25 megawatt electrical output to any utility power distribution system for sale. Any steam supplied to a steam distribution system for the purpose of providing steam to a steam-electric generator that would produce electrical energy for sale is also considered in determining the electrical energy output capacity of the affected facility.

"Emissions cap" means any limitation on the rate of emissions of any 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 that emits or would have the potential to emit any regulated NSR pollutant and includes an electric steam generating unit. For purposes of this article, there are two types of emissions units: (i) a new emissions unit is any emissions unit that is (or will be) newly constructed and that has existed for less than two years from the date such emissions unit first operated; and (ii) an existing emissions unit is any emissions unit that is not a new emissions unit. A replacement unit is an existing emissions unit.

"Enforceable as a practical matter" means that the permit contains emission limitations that are enforceable by the board or the department and meet the following criteria:

a. Are permanent;

b. Contain a legal obligation for the owner to adhere to the terms and conditions;

c. Do not allow a relaxation of a requirement of the implementation plan;

d. Are technically accurate and quantifiable;

e. Include averaging times or other provisions that allow at least monthly (or a shorter period if necessary to be consistent with the implementation plan) checks on compliance.

f. Require a level of recordkeeping, reporting and monitoring sufficient to demonstrate compliance.

"Federal land manager" means, with respect to any lands in the United States, the secretary of the department with authority over such lands.

"Federally enforceable" means all limitations and conditions that 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:

a. Emission standards, alternative emission standards, alternative emission limitations, and equivalent emission limitations established pursuant to § 112 of the federal Clean Air Act as amended in 1990.

b. New source performance standards established pursuant to § 111 of the federal Clean Air Act, and emission standards established pursuant to § 112 of the federal Clean Air Act before it was amended in 1990.

c. All terms and conditions (unless expressly designated as not federally enforceable) in a federal operating permit, including any provisions that limit a source's potential to emit.

d. Limitations and conditions that are part of an implementation plan established pursuant to § 110, 111(d), or 129 of the federal Clean Air Act.

e. Limitations and conditions (unless expressly designated as not federally enforceable) that are part of a federal construction permit issued under 40 CFR 52.21 or any construction permit issued under regulations approved by EPA into the implementation plan.

f. Limitations and conditions (unless expressly designated as not federally enforceable) that are part of a state operating permit where the permit and the permit program pursuant to which it was issued meet all of the following criteria:

(1) The operating permit program has been approved by the EPA into the implementation plan under § 110 of the federal Clean Air Act.

(2) The operating permit program imposes a legal obligation that operating permit holders adhere to the terms and limitations of such permits and provides that permits that do not conform to the operating permit program requirements and the requirements of EPA's underlying regulations may be deemed not "federally enforceable" by EPA.

(3) The operating permit program requires that all emission limitations, controls, and other requirements imposed by such permits will be at least as stringent as any other applicable limitations and requirements contained in the implementation plan or enforceable under the implementation plan, and that the program may not issue permits that waive, or make less stringent, any limitations or requirements contained in or issued pursuant to the implementation plan, or that are otherwise "federally enforceable."

(4) The limitations, controls, and requirements in the permit in question are permanent, quantifiable, and otherwise enforceable as a practical matter.

(5) The permit in question was issued only after adequate and timely notice and opportunity for comment by the EPA and the public.

g. Limitations and conditions in a regulation of the board or program that has been approved by EPA under subpart E of 40 CFR Part 63 for the purposes of implementing and enforcing § 112 of the federal Clean Air Act.

h. Individual consent agreements that EPA has legal authority to create.

"Federal operating permit" means a permit issued under the federal operating permit program.

"Federal operating permit program" means an operating permit system (i) for issuing terms and conditions for major stationary sources, (ii) established to implement the requirements of Title V of the federal Clean Air Act and associated regulations, and (iii) codified in Article 1 (9VAC5-80-50 et seq.), Article 2 (9VAC5-80-310 et seq.), Article 3 (9VAC5-80-360 et seq.), and Article 4 (9VAC5-80-710 et seq.) of this part.

"Fugitive emissions" means those emissions that could not reasonably pass through a stack, chimney, vent, or other functionally equivalent opening.

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

a. The most stringent emissions limitation that 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

b. The most stringent emissions limitation that is achieved in practice by such class or category of stationary sources. 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.

"Major emissions unit" means (i) any emissions unit that emits or has the potential to emit 100 tons per year or more of the PAL pollutant in an attainment area; or (ii) any emissions unit that emits or has the potential to emit the PAL pollutant in an amount that is equal to or greater than the major source threshold for the PAL pollutant for nonattainment areas in subdivision a (1) of the definition of "major stationary source."

"Necessary preconstruction approvals or permits" means those permits required under the NSR program that are part of the applicable implementation plan.

"Net emissions increase" means:

a. With respect to any regulated NSR pollutant emitted by a major stationary source, the amount by which the sum of the following exceeds zero:

(1) The increase in emissions from a particular physical change or change in the method of operation at a stationary source as calculated pursuant to 9VAC5-80-2000 H; and

(2) Any other increases and decreases in actual emissions at the major stationary source that are contemporaneous with the particular change and are otherwise creditable. Baseline actual emissions for calculating increases and decreases under this subdivision shall be determined as provided in the definition of "baseline actual emissions," except that subdivisions a (3) and b (4) of that definition shall not apply.

b. An increase or decrease in actual emissions is contemporaneous with the increase from the particular change only if it occurs before the date that the increase from the particular change occurs. For sources located in ozone nonattainment areas classified as serious or severe in 9VAC5-20-204, an increase or decrease in actual emissions of volatile organic compounds or nitrogen oxides is contemporaneous with the increase from the particular change only if it occurs during a period of five consecutive calendar years which includes the calendar year in which the increase from the particular change occurs.

c. An increase or decrease in actual emissions is creditable only if:

(1) It occurs between the date five years before construction on the particular change commences and the date that the increase from the particular change occurs; and

(2) The board has not relied on it in issuing a permit for the source pursuant to this article which permit is in effect when the increase in actual emissions from the particular change occurs.

d. An increase in actual emissions is creditable only to the extent that the new level of actual emissions exceeds the old level.

e. A decrease in actual emissions is creditable only to the extent that:

(1) The old level of actual emissions or the old level of allowable emissions, whichever is lower, exceeds the new level of actual emissions;

(2) It is enforceable as a practical matter at and after the time that actual construction on the particular change begins;

(3) The board has not relied on it in issuing any permit pursuant to this chapter or the board has not relied on it in demonstrating attainment or reasonable further progress in the implementation plan; and

(4) It has approximately the same qualitative significance for public health and welfare as that attributed to the increase from the particular change.

f. An increase that results from a physical change at a source occurs when the emissions unit on which construction occurred becomes operational and begins to emit a particular pollutant. Any replacement unit that requires shakedown becomes operational only after a reasonable shakedown period, not to exceed 180 days.

g. Subdivision a of the definition of "actual emissions" shall not apply for determining creditable increases and decreases or after a change.

Secondary emissions do not count in determining the potential to emit of a stationary source. For the purposes of actuals PALs, 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 the effect it would have on emissions is federally enforceable or enforceable as a practical matter by the state.

"Predictive emissions monitoring system" or "PEMS" means all of the equipment necessary to monitor process and control device operational parameters (for example, control device secondary voltages and electric currents) and other information (for example, gas flow rate, O2 or CO2 concentrations), and calculate and record the mass emissions rate (for example, pounds per hour) on a continuous basis.

"Prevention of significant deterioration (PSD) program" means a preconstruction review and permit program (i) for new major stationary sources or major modifications (physical changes or changes in the method of operation), (ii) established to implement the requirements of § 165 of the federal Clean Air Act and associated regulations, and (iii) codified in Article 8 (9VAC5-80-1605 et seq.) of this part.

In determining the projected actual emissions before beginning actual construction, the owner shall:

a. Consider all relevant information, including but not limited to, historical operational data, the company's own representations, the company's expected business activity and the company's highest projections of business activity, the company's filings with the state or federal regulatory authorities, and compliance plans under the approved plan;

b. Include fugitive emissions to the extent quantifiable, and emissions associated with startups, shutdowns, and malfunctions; and

c. Exclude, in calculating any increase in emissions that results from the particular project, that portion of the unit's emissions following the project that an existing unit could have emitted during the consecutive 24-month period used to establish the baseline actual emissions and that are also unrelated to the particular project, including any increased utilization due to product demand growth, provided such exclusion shall not reduce any calculated increases in emissions that are caused by, result from, or are related to the particular project; or

d. In lieu of using the method set out in subdivisions a, b, and c of this definition, may elect to use the emissions unit's potential to emit, in tons per year, as defined under the definition of "potential to emit."

"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.

"Reasonable further progress" means the annual incremental reductions in emissions of a given air pollutant (including substantial reductions in the early years following approval or promulgation of an implementation plan and regular reductions thereafter) which are sufficient in the judgment of the board to provide for attainment of the applicable ambient air quality standard within a specified nonattainment area by the attainment date prescribed in the implementation plan for such area.

"Reasonably available control technology" or "RACT" means the lowest emission limit that a particular source is capable of meeting by the application of control technology that is reasonably available, considering technological and economic feasibility.

c. Any pollutant that is identified under this subdivision as a constituent or precursor of a general pollutant listed under subdivision a or b of this definition, provided that such constituent or precursor pollutant may only be regulated under this article as part of regulation of the general pollutant. Precursors identified for purposes of this article shall be the following:

(4) Volatile organic compounds and ammonia are presumed not to be precursors to PM2.5 in any PM2.5 nonattainment area, unless the board determines that emissions of volatile organic compounds or ammonia from sources in a specific area are a significant contributor to that area's ambient PM2.5 concentrations.

d. PM2.5 emissions and PM10 emissions shall include gaseous emissions from a source or activity that condense to form particulate matter at ambient temperatures. On or after January 1, 2011, such condensable particulate matter shall be accounted for in applicability determinations and in establishing emissions limitations for PM2.5 and PM10 in permits issued under this article. Compliance with emissions limitations for PM2.5 and PM10 issued prior to this date shall not be based on condensable particulate matter unless required by the terms and conditions of the permit. Applicability determinations made prior to this date without accounting for condensable particulate matter shall not be considered in violation of this article.

"Replacement unit" means an emissions unit for which all the following criteria are met. No creditable emission reductions shall be generated from shutting down the existing emissions unit that is replaced.

b. The emissions unit is identical to or functionally equivalent to the replaced emissions unit.

c. The replacement does not alter the basic design parameters of the process unit.

d. The replaced emissions unit is permanently removed from the major stationary source, otherwise permanently disabled, or permanently barred from operation by a permit that is enforceable as a practical matter. If the replaced emissions unit is brought back into operation, it shall constitute a new emissions unit.

"Secondary emissions" means emissions that would occur as a result of the construction or operation of a major stationary source or major modification, but do not come from the major stationary source or major modification itself. For the purpose of this article, secondary emissions shall be specific, well defined, quantifiable, and affect the same general area as the stationary source or modification 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 major stationary source or major modification. Secondary emissions do not include any emissions that come directly from a mobile source, such as emissions from the tailpipe of a motor vehicle, from a train, or from a vessel.

"Significant" means, in reference to a net emissions increase or the potential of a source to emit any of the following pollutants, a rate of emissions that would equal or exceed any of the following rates:

4. Alteration and additions of existing structures as specifically required by new or existing applicable environmental legislation or environmental regulations (for example, hush houses for aircraft engines and scrubbers for air emissions).

5. Direct emissions from remedial and removal actions carried out under CERCLA and associated regulations to the extent the emissions either comply with the substantive requirements of the new source review program or are exempted from other environmental regulation under the provisions of CERCLA and applicable regulations issued under CERCLA.

Federal actions which are part of a continuing response to an emergency or disaster under subdivision G 2 of this section and which are to be taken more than six months after the commencement of the response to the emergency or disaster under subdivision G 2 of this section are exempt from the requirements of this subsection only if:

1. The federal agency taking the actions makes a written determination that, for a specified period not to exceed an additional six months, it is impractical to prepare the conformity analyses which would otherwise be required and the actions cannot be delayed due to overriding concerns for public health and welfare, national security interests, and foreign policy commitments; or

2. For actions which are to be taken after those actions covered by subdivision H 1 of this section, the federal agency makes a new determination as provided in subdivision H 1 of this section, and:

a. Provides a draft copy of the written determinations required to affected EPA regional offices, the affected states and air pollution control agencies, and any federally recognized Indian tribal government in the nonattainment or maintenance area. Those organizations shall be allowed 15 days from the beginning of the extension period to comment on the draft determination; and

b. Within 30 days after making the determination, publish a notice of the determination by placing a prominent advertisement in a daily newspaper of general circulation in the area affected by the action.

If additional actions are necessary in response to an emergency or disaster under subdivision G 2 of this section beyond the specified time period in subdivision 2 of this subsection, a federal agency may make a new written determination as described in subdivision 2 of this subsection for as many six-month periods as needed, but in no case shall this exemption extend beyond three six-month periods except where an agency provides information to EPA and the department stating that the conditions that gave rise to the emergency exemption continue to exist and how such conditions effectively prevent the agency from conducting a conformity evaluation.

I. Notwithstanding other requirements of this chapter, actions specified by individual federal agencies that have met the criteria set forth in subdivision J 1, J 2, or J 3 of this section and the procedures set forth in subsection K of this section are presumed to conform, except as provided in subsection M of this section. Actions specified by individual federal agencies as presumed to conform shall not be used in combination with one another when the total direct and indirect emissions from the combination of actions would equal or exceed any of the rates specified in subdivision E 1 or E 2 of this section.

J. The federal agency shall meet the criteria for establishing activities that are presumed to conform by fulfilling the requirements set forth in either subdivision 1, 2, or 3 of this subsection.

1. The federal agency shall clearly demonstrate, using methods consistent with this regulation, that the total of direct and indirect emissions from the type of activities which would be presumed to conform would not:

a. Cause or contribute to any new violation of any standard in any area;

b. Interfere with the provisions in the applicable implementation plan for maintenance of any standard;

c. Increase the frequency or severity of any existing violation of any standard in any area;

d. Delay timely attainment of any standard or any required interim emissions reductions or other milestones in any area including, where applicable, emission levels specified in the applicable implementation plan for purposes of:

(1) A demonstration of reasonable further progress;

(2) A demonstration of attainment; or

(3) A maintenance plan.

2. The federal agency shall provide documentation that the total of direct and indirect emissions from the future actions would be below the emission rates for a conformity determination that are established in subsection B of this section, based, for example, on similar actions taken over recent years.

3. The federal agency shall clearly demonstrate that the emissions from the type or category of actions and the amount of emissions from the action are included in the applicable implementation plan and the department provides written concurrence that the emissions from the actions along with all other expected emissions in the area will not exceed the emission budget in the applicable implementation plan.

K. In addition to meeting the criteria for establishing exemptions set forth in subdivision J 1, J 2, or J 3 of this section, the following procedures shall also be complied with to presume that activities shall conform:

1. The federal agency shall identify through publication in the Federal Register its list of proposed activities that are presumed to conform, and the basis for the presumptions. The notice shall clearly identify the type and size of the action that would be presumed to conform and provide criteria for determining if the type and size of action qualifies it for the presumption;

2. The federal agency shall notify the appropriate EPA regional office or offices, department, and local air quality agencies and, where applicable, the lead planning organization, and the metropolitan planning organization and provide at least 30 days for the public to comment on the list of proposed activities presumed to conform. If the presumed to conform action has regional or national application (e.g., the action will cause emission increases in excess of the de minimis levels identified in subsection E of this section in more than one EPA region), the federal agency, as an alternative to sending it to EPA regional offices, may send the draft conformity determination to EPA, Office of Air Quality Planning and Standards;

3. The federal agency shall document its response to all the comments received and make the comments, response, and final list of activities available to the public upon request; and

4. The federal agency shall publish the final list of such activities in the Federal Register.

L. Emissions from the following actions are presumed to conform:

1. Actions at installations with facility-wide emission budgets meeting the requirements in 9VAC5-160-181 provided that the department has included the emission budget in the EPA-approved applicable implementation plan and the emissions from the action along with all other emissions from the installation will not exceed the facility-wide emission budget.

2. Prescribed fires conducted in accordance with a smoke management program that meets the requirements of EPA's Interim Air Quality Policy on Wildland and Prescribed Fires (April 1998) or an equivalent replacement EPA policy.

3. Emissions for actions that the department identifies in the EPA-approved applicable implementation plan as presumed to conform.

M. Even though an action would otherwise be presumed to conform under subsection I or L of this section, an action shall not be presumed to conform and the requirements of 9VAC5-160-110 through 9VAC5-160-180, 9VAC5-160-182 through 9VAC5-160-184, and 9VAC5-160-190 shall apply to the action if EPA or a third party shows that the action would:

1. Cause or contribute to any new violation of any standard in any area;

2. Interfere with provisions in the applicable implementation plan for maintenance of any standard;

3. Increase the frequency or severity of any existing violation of any standard in any area; or

4. Delay timely attainment of any standard or any required interim emissions reductions or other milestones in any area including, where applicable, emission levels specified in the applicable implementation plan for purposes of (i) a demonstration of reasonable further progress, (ii) a demonstration of attainment, or (iii) a maintenance plan.

N. Any measures used to affect or determine applicability of this chapter, as determined under this section, shall result in projects that are in fact de minimis, shall result in the de minimis levels prior to the time the applicability determination is made, and shall be state or federally enforceable. Any measures that are intended to reduce air quality impacts for this purpose shall be identified (including the identification and quantification of all emission reductions claimed) and the process for implementation (including any necessary funding of the measures and tracking of the emission reductions) and enforcement of the measures shall be described, including an implementation schedule containing explicit timelines for implementation. Prior to a determination of applicability, the federal agency making the determination shall obtain written commitments from the appropriate persons or agencies to implement any measures which are identified as conditions for making the determinations. The written commitment shall describe the mitigation measures and the nature of the commitment, in a manner consistent with the previous sentence. After this regulation is approved by EPA, enforceability through the applicable implementation plan of any measures necessary for a determination of applicability shall apply to all persons who agree to reduce direct and indirect emissions associated with a federal action for a conformity applicability determination.
