COMMONWEALTH OF VIRGINIA

STATUS OF § 110(a)(2) REQUIREMENTS IN THE 

VIRGINIA STATE IMPLEMENTATION PLAN

A State Implementation Plan (SIP) is a plan for each state that identifies how that state 

will attain and maintain the primary and secondary National Ambient Air Quality 

Standards (NAAQS). The SIP contains regulations, source-specific requirements, nonregulatory items such as plans and inventories, and other types of submittals designed 

to satisfy requirements promulgated by the U.S. Environmental Protection Agency 

(EPA). The initial SIPs for states were approved on May 31, 1972. SIPs may be 

revised by the state with EPA approval. The federally enforceable SIP for the 

Commonwealth of Virginia is compiled in Subpart VV of 40 CFR Part 52.

Section 110(a) of the federal Clean Air Act (CAA) requires that each SIP provide for the 

implementation, maintenance, and enforcement of the NAAQS. This section also 

requires that within three years of the promulgation of a NAAQS, a state must adopt and 

submit such a plan to EPA. These infrastructure SIPs provide assurances of state 

resources and authorities. Where necessary, the infrastructure SIPs establish the basic 

state programs to implement, maintain, and enforce new or revised standards. Often, 

these SIPs simply reaffirm that the appropriate framework exists for any new NAAQS. 

The requirements of § 110(a)(2) in the CAA relevant to the 2013 fine particulate (PM2.5)

NAAQS that are required to be in Virginia’s SIP are already contained in Virginia’s 

current SIP, have been submitted to EPA, or are contained herein.

Not all requirements of § 110(a)(2) need to be addressed as part of the infrastructure 

SIP submittal. The omitted requirements are as follows:

• Section 110(a)(2)(I): Information regarding § 110(a)(2)(I) for nonattainment area 

plan revisions is not included. The specific plan submissions for designated 

nonattainment areas, as required under CAA title I part D, are subject to different 

submission schedules than those for § 110(a) infrastructure elements. 

Therefore, EPA does not require infrastructure submissions to address § 

110(a)(2)(I).

• Section 110(a)(2)(J), visibility: The promulgation of new or revised NAAQS does

not include new visibility protection requirements under the CAA, title I, part C. 

Therefore, states are not required to implement visibility protection obligations 

pursuant to § 110(a)(2)(J) based on the promulgation of a new or revised 

NAAQS, and EPA does not require infrastructure submissions to address this 

requirement under § 110(a)(2)(J).

EPA set the first NAAQS for PM2.5 on July 18, 1997 (62 FR 38652). Prior to the 1997 

PM2.5 NAAQS, regulated particle pollution consisted of Total Suspended Particulate 

(TSP) or particulate with a diameter of less than 10 angstroms (PM10). The 1997 PM2.5
2

NAAQS was the first NAAQS to regulate particles with a diameter of less than 2.5 

angstroms. The 1997 PM2.5 NAAQS set a 24-hour standard of 65 μg/m3 and an annual 

standard of 15.0 μg/m3. On October 17, 2006 (71 FR 61144), EPA finalized a new 

PM2.5 NAAQS, which reduced the 24-hour standard to 35 μg/m3 while leaving the 

annual standard at 15.0 μg/m3. EPA further strengthened protections for PM2.5 pollution 

on January 15, 2013 (78 FR 3086). The 2013 PM2.5 NAAQS reduced the primary 

health standard for PM2.5 to 12.0 μg/m3 and left the remaining standards in place. 

Governors may submit recommendations for nonattainment areas within one year of a 

standard being promulgated. Virginia submitted a designation recommendation letter to 

EPA on December 13, 2013, in which Virginia recommended a designation of 

attainment for the entire Commonwealth based on air quality trends and compliant air 

quality monitoring data. On January 15, 2015, EPA finalized the air quality designations 

for the 2013 PM2.5 NAAQS (80 FR 2206). EPA designated all of Virginia as attainment 

for the 2013 PM2.5 NAAQS.

The following describes each specific EPA requirement and how the Commonwealth 

meets each requirement.

Section 110(a)(2)(A): "Each such plan shall include enforceable emission limitations 

and other control measures, means, or techniques (including economic incentives such 

as fees, marketable permits, and auctions of emissions rights), as well as schedules 

and timetables for compliance, as may be necessary or appropriate to meet the 

applicable requirements of this Act;"

Virginia’s enforceable emission limitations and other control measures are those 

provisions of the following chapters that have been approved in Virginia’s SIP in 

40 CFR 52.2420(c).

 9VAC5 Chapter 40 (Existing Stationary Sources)

 9VAC5 Chapter 45 (Commercial and Consumer Products) 

 9VAC5 Chapter 50 (New and Modified Stationary Sources)

 9VAC5 Chapter 91 (Motor Vehicle Inspection and Maintenance Program 

for Northern Virginia)

Section 110(a)(2)(B): "Each such plan shall provide for establishment and operation of 

appropriate devices, methods, systems, and procedures necessary to – (i) monitor, 

compile, and analyze data on ambient air quality, and (ii) upon request, make such data 

available to the Administrator;"

Virginia maintains and operates a multi-station PM2.5 network to measure 

ambient concentrations within the Commonwealth for comparison to the NAAQS. 

All data is measured using EPA-approved methods as either reference or 

equivalent monitors; all monitors are subject to the quality assurance 

requirements of 40 CFR Part 58; and all samplers are located at sites that have 

met the minimum siting requirements of Part 58. The data is submitted to EPA’s 
3

Air Quality System (AQS) in accordance with the schedule prescribed by 40 CFR 

Part 58.

In order to keep EPA informed of changes to the sampling network, Virginia 

provides EPA Region III with prior notification of any planned changes to the 

network. As needed, details of these changes and anticipated approvals of the 

changes are communicated to EPA. On an annual basis, Virginia sends EPA a 

summary of all past and projected changes to the network. This summary 

provides a description of each change, the reason for each change, and any 

other information relevant to the change. EPA has approved the most recent 

summary, which was submitted for 2014. This summary will be updated as 

required by federal regulations and is currently updated on an annual basis.

Section 10.1-1306 of the Code of Virginia, "Inspections, investigations, etc.,"

states:

The Board shall make, or cause to be made, such investigations 

and inspections and do such other things as are reasonably 

necessary to carry out the provisions of this chapter, within the 

limits of the appropriations, study grants, funds, or personnel which 

are available for the purposes of this chapter, including the 

achievement and maintenance of such levels of air quality as will 

protect human health, welfare and safety and to the greatest 

degree practicable prevent injury to plant and animal life and 

property...

This section of the Code of Virginia supports the development and maintenance 

of an adequate monitoring network to ensure the achievement and maintenance 

of healthy levels of air quality.

Section 110(a)(2)(C): "Each such plan shall include a program to provide for the 

enforcement of the measures described in paragraph (A), and regulation of the 

modification and construction of any stationary source within the areas covered by the 

plan as necessary to assure that national ambient air quality standards are achieved, 

including a permit program as required in parts C and D;"

Enforcement provisions and permit provisions are found in those portions of Part 

V (Enforcement) of 9VAC5 Chapter 170 (General Administration) and 9VAC5 

Chapter 80 (Permits for Stationary Sources) that are listed in 40 CFR 52.2420. 

Virginia has a minor new source review permitting program under 9VAC5-80-10 

and 9VAC5-80-11 (Permits for New and Modified Stationary Sources). Article 8 

(Permits for Major Stationary Sources and Major Modifications Locating in 

Prevention of Significant Deterioration Areas) of Part II of 9VAC5 Chapter 80 

provides that construction and modification of major stationary sources in 

prevention of significant deterioration (PSD) areas will not cause or contribute to 

a violation of any NAAQS, including the 2013 PM2.5 NAAQS. EPA approved 

Virginia’s most recent PSD SIP revision on February 25, 2014 (79 FR 10377), 
4

and therefore Virginia’s SIP-approved permit program addresses this 

infrastructure element for the 2013 PM2.5 NAAQS. Virginia’s PSD program 

applies to greenhouse gases through 9VAC5 Chapter 85, Permits for Stationary 

Sources of Pollutants Subject to Regulation, which implements EPA’s 

greenhouse gas tailoring requirements. Other aspects for enforcement are found 

in the source monitoring, source testing and test methods, and record keeping 

and reporting provisions of 9VAC5 Chapters 40 and 50 that are listed in 40 CFR 

52.2420.

Section 110(a)(2)(D)(i)(II): "Each such plan shall contain adequate provisions

prohibiting, consistent with the provisions of this title, any source or other type of 

emissions activity within the State from emitting any air pollution in amounts which will 

interfere with measures required to be included in the applicable implementation plan 

for any other State under Part C to prevent significant deterioration of air quality or to 

protect visibility;"

Virginia's PSD permitting program is regulated under Article 8 (Permits for Major 

Stationary Sources and Major Modifications Locating in Prevention of Significant 

Deterioration Areas) of Part II of 9VAC5 Chapter 80. This program provides that 

construction and modification of major stationary sources in PSD areas will not 

cause or contribute to a violation of any NAAQS, including the 2013 PM2.5 

NAAQS. EPA approved Virginia’s most recent PSD SIP revision on February 25, 

2014 (79 FR 10377), and therefore Virginia’s SIP-approved permit program 

addresses this infrastructure element for the 2013 PM2.5 NAAQS. Virginia’s PSD 

program applies to greenhouse gases through 9VAC5 Chapter 85, Permits for 

Stationary Sources of Pollutants Subject to Regulation, which implements EPA’s 

greenhouse gas tailoring requirements. With respect to sources located in 

nonattainment areas and thus not subject to the PSD process, Virginia’s SIP 

includes a fully approved nonattainment permitting program under Article 9 

(Permits for Major Stationary Sources and Major Modifications Locating in 

Nonattainment Areas or the Ozone Transport Region) of Part II of 9VAC5 

Chapter 80 (Permits for Major Stationary Sources).

On October 4, 2010, Virginia submitted a Regional Haze SIP revision to meet the 

regulatory requirements of Subpart P of 40 CFR Part 51 and statutory 

requirements set forth at CAA §§ 169A and 169B. EPA granted limited approval 

of this SIP revision on June 13, 2012 (77 FR 35287). EPA granted a limited 

disapproval due to the Clean Air Interstate Rule (CAIR) remand by the D.C. 

Circuit since the Virginia Regional Haze SIP relied upon CAIR for Best Available 

Retrofit Technology (BART) for electric generating units (EGUs) and reasonable 

progress analyses. On July 16, 2015, Virginia submitted a SIP revision asserting 

Virginia will rely upon the provisions of the Cross State Air Pollution Rule 

(CSAPR) and not CAIR for BART for EGUs and for reasonable progress. Since 

CAIR has sunset and CSAPR implementation has commenced, reliance upon 

CSAPR rather than CAIR in no way weakens the protections to visibility and 

visibility improvements contained with the Virginia Regional Haze SIP. These 

requirements will help ensure that Virginia EGU emissions will not interfere with 
5

neighboring states’ reasonable progress toward visibility improvement in Class I 

areas. The 2010 Regional Haze SIP plus the July 2015 Regional Haze SIP 

submission, once approved by EPA, satisfy Virginia’s obligations regarding § 

110(a)(2)(D)(i)(II).

Major stationary sources for PM2.5 in Virginia are currently subject to 

nonattainment and PSD NSR permitting programs. These provisions to 

implement Part C may be found in Article 8 (Permits for Major Stationary Sources

and Major Modifications Locating in Prevention of Significant Deterioration Areas)

of Part II of 9 VAC5 Chapter 80 (Permits for Stationary Sources).

Section 110(a)(2)(D)(ii): Each such plan shall contain adequate provisions insuring 

compliance with the applicable requirements of §§ 126 and 115 (relating to interstate 

and international pollution abatement)

Section 126(a) directs each SIP to include provisions requiring a new or modified 

source to notify neighboring states of potential impacts from that source. Major 

stationary sources of PM2.5 in Virginia are currently subject to PSD NSR 

permitting programs. These provisions to implement Part C may be found in 

Article 8 (Permits for Major Stationary Sources and Major Modifications Locating 

in Prevention of Significant Deterioration Areas) of Part II of 9VAC5 Chapter 80

(Permits for Stationary Sources), and in 9VAC5 Chapter 85 (Permits for 

Stationary Sources Subject to Regulation). These regulations have been 

approved in Virginia’s SIP in 40 CFR 52.2420(c). 9VAC5-80-1775 specifically 

requires notification to local air pollution control agencies and any state whose 

lands may be affected by emissions from the source or modification. Virginia is 

not subject to any pending actions or petitions regarding PM2.5 under §§ 115, 

126(b), or 126(c). No source or sources within Virginia are the subject of an 

active finding under § 126 with respect to any pollutant. There are no final 

findings under § 115 against Virginia with respect to any pollutant.

Section 110(a)(2)(E)(i): "Each such plan shall provide necessary assurances that the 

State (or, except where the Administrator deems inappropriate, the general purpose 

local government or governments, or a regional agency designated by the State or 

general purpose local governments for such purpose) will have adequate personnel, 

funding, and authority under State (and, as appropriate, local) law to carry out such 

implementation plan (and is not prohibited by any provision of Federal or State Law 

from carrying out such implementation plan or portion thereof)."

Code of Virginia, Title 10.1, Chapter 13, Air Pollution Control Board, gives broad 

authority to develop, implement, and enforce the implementation plan. Section 

10.1-1308 provides the board adequate legal authority to adopt emission 

standards and compliance schedules applicable to regulated entities. This 

section provides authority to adopt emission standards, limitations, and any other 

measures necessary for attainment and maintenance of national standards. 

Sections 10.1-1307, 10.1-1307.3, 10.1-1309, 10.1-1316, 10.1-1320, and 10.1-

1322 provide the board adequate legal authority to enforce applicable laws, 
6

regulations standards, and compliance schedules. The provisions also allow for 

injunctive relief. In addition, § 10.1-1186 provides the department legal authority 

to enforce applicable laws, regulations, standards, and compliance schedules.

The resources to carry out the implementation plan are provided through general 

funds, Title V funds, and the §§ 103 and 105 grant process. 

Virginia's Title V fee requirements are located in Article 2 (Permit Program 

Emissions Fees for Stationary Sources) of 9VAC5-80 (Permits for Stationary 

Sources). These regulations are part of Virginia’s federally approved Title V 

program and are codified in Appendix A of 40 CFR Part 70, Approval Status of 

State and Local Operating Permits Programs. Additionally, Title V fees are 

collected under the authority of § 10.1-1322. Changes in future years to this 

funding mechanism would require changes to legal authority. 

Virginia has adequate personnel to carry out the SIP with respect to PM2.5

requirements. Should EPA determine that Virginia lacks adequate personnel to 

carry out the SIP, EPA may issue a finding with respect to that deficiency. 

Virginia would then have a legal obligation to correct that deficiency.

Section 110(a)(2)(E)(ii): "Each such plan shall provide requirements that the State 

comply with the requirements respecting State boards under § 128."

The board has the authority to approve regulations, enforcement actions, and 

permits. Section 10.1-1302 is as stringent as § 128(a)(1) of the Clean Air Act 

and ensures that at least a majority of the members of the board represent the 

public interest and do not derive any significant portion of their income from 

persons subject to permits or enforcement orders of the board as required by § 

128(a)(1) of the Clean Air Act. See Virginia’s SIP revision submitted on June 8, 

2010 and approved by EPA on October 11, 2011 (76 FR 62635). In addition, the 

State or Local Government Conflict of Interests Act (§ 2.2-3100 et seq.) provides 

the means for disclosure of potential conflicts of interest as required by §

128(a)(2) of the Clean Air Act. Virginia submitted a revision to the Regulation for 

General Administration (9VAC5-170) on December 22, 2014, to ensure that this 

provision of the Clean Air Act is adequately addressed. EPA published final 

approval of this revision on April 2, 2015 (80 FR 17692).

Section 110(a)(2)(E)(iii): "Each such plan shall provide necessary assurances that, 

where the State has relied on a local or regional government, agency, or instrumentality 

for the implementation of any plan provision, the State has responsibility for ensuring 

adequate implementation of such plan provision;"

Virginia does not rely on localities to implement SIP provisions regarding the 

2013 PM2.5 NAAQS.

Section 110(a)(2)(F)(i): "Each such plan shall require, as may be prescribed by the 

Administrator, the installation, maintenance, and replacement of equipment, and the 
7

implementation of other necessary steps, by owners or operators of stationary sources 

to monitor emissions from such sources;"

These requirements are included in those provisions of 9VAC5 Chapters 20, 40, 

50, and 80 that are approved in the SIP under 40 CFR 52.2420. Additionally, 

Virginia’s SIP contains no provision preventing the use of any credible evidence.

Section 110(a)(2)(F)(ii): "Each such plan shall require, as may be prescribed by the 

Administrator, periodic reports on the nature and amounts of emissions and emissionsrelated data from such sources;"

Requirements for periodic reports on the nature and amounts of emissions and 

emissions-related data are included in 9VAC5-20-160 (Registration) of 9VAC5 

Chapter 20 (General Provisions). Such data are also required by Part I of 

9VAC5 Chapter 40 (Existing Stationary Sources) as well as Parts I and II of 

9VAC5 Chapter 50 (New and Modified Stationary Sources). These SIP 

provisions are approved under 40 CFR 52.2420. 

Compliance certification requirements and compliance assurance monitoring 

requirements applicable to Title V facilities are located in Article 1, Federal 

Operating Permits for Stationary Sources (9VAC5-80-50 et seq.) of 9VAC5-80 

(Permits for Stationary Sources), and specifically at 9VAC5-80-80 and 9VAC5-

80-110, respectively. These regulations are part of Virginia’s federally approved 

Title V program and are codified in Appendix A of 40 CFR Part 70, Approval 

Status of State and Local Operating Permits Programs.

Virginia meets all requirements of Subpart A of 40 CFR Part 51, Air Emissions 

Reporting Requirements. Should requirements for data submittals change as a 

result of the 2013 PM2.5 NAAQS, Virginia has authority under 9VAC5-20-160 to 

request and gather that information.

Section 110(a)(2)(F)(iii): "Each such plan shall require, as may be prescribed by the 

Administrator, correlation of such reports by the State agency with any emission 

limitations or standards established pursuant to this Act, which reports shall be available 

at reasonable times for public inspection;"

The correlation of such reports is included in Part I of 9VAC5 Chapter 40 and 

Part II of 9VAC5 Chapter 50. 9VAC5-170-60 (Availability of information) of Part II 

of 9VAC5 Chapter 170 (Regulation for General Administration) requires that 

these reports be publicly available. These SIP provisions are approved under 40 

CFR 52.2420.

Section 110(a)(2)(G): "Each such plan shall provide for authority comparable to that in 

§ 303 and adequate contingency plans to implement such authority;"

Section 10.1-1309 B under Code of Virginia, Title 10.1, Chapter 13, Air Pollution 

Control Board, authorizes the board to declare a state of emergency and issue 
8

without hearing an emergency special order directing the owner to cease such 

pollution immediately upon finding that any owner is unreasonably affecting the 

public health, safety or welfare; the health of animal or plant life; or property. 

Section 10.1-1309.1 authorizes the board to issue special orders requiring plans 

to abate, control, prevent, remove, or contain any substantial and imminent threat 

to public health or the environment that is reasonably likely to occur if such 

source ceases operations. 

Virginia’s emergency plans are found in 9VAC5-70 (Air Pollution Episode 

Prevention) and are approved in 40 CFR 52.2420. Virginia has never monitored 

and recorded a 24-hour PM2.5 level greater than 140.4 μg/m3 since 2006 (see 

attached AQS Quicklook report.) Since this level has never been exceeded in 

any area of the Commonwealth, Virginia has appropriate general emergency 

powers to address PM2.5 related episodes, and no specific emergency episode 

plan is necessary at this time.

Section 110(a)(2)(H)(i): "Each such plan shall provide for revision of such plan from 

time to time as may be necessary to take account of revisions of such national primary 

or secondary ambient air quality standard or the availability of improved or more 

expeditious methods of attaining such standard;"

Virginia’s SIP is a compilation of regulations, plans, and other submittals that act 

to improve and maintain air quality at the national standards. The authority to 

develop or revise the SIP is based on the authority to adopt new regulations, 

revise existing regulations, and conduct business in a manner to meet the 

NAAQS. Code of Virginia, Title 10.1, Chapter 13, Air Pollution Control Board, 

gives broad authority to perform these functions. Specifically § 10.1-1306 

provides authority for the board to act reasonably to achieve and maintain levels 

of air quality that will protect human health, welfare, and safety. Also, § 10.1-

1307 provides for the development of a comprehensive program for the study, 

abatement, and control of all sources of air pollution in the Commonwealth. 

Section 10.1-1308 provides authority to promulgate regulations to abate, control, 

and prohibit air pollution throughout the Commonwealth in accordance with the 

provisions of Virginia’s Administrative Process Act. 

Section 110(a)(2)(H)(ii): "Each such plan shall provide for revision of such plan except 

as provided in paragraph (3)(c), whenever the Administrator finds on the basis of 

information available to the Administrator that the plan is substantially inadequate to 

attain the national ambient air quality standard which it implements or to otherwise 

comply with any additional requirements established under this Act;"

As noted in the prior paragraph, § 10.1-1306 provides authority for the board to 

act reasonably to achieve and maintain levels of air quality that will protect 

human health, welfare, and safety. Virginia affirms that the state implementation 

plan may be revised should the Administrator find that the plan is substantially 

inadequate to attain a standard or to comply with any additional requirements 

under the Act.
9

Section 110(a)(2)(J): "Each such plan shall meet the applicable requirements of 

section 121 (relating to consultation), section 127 (relating to public notification), and 

part C (relating to prevention of significant deterioration of air quality and visibility 

protection);"

Section 121: All SIP revisions undergo public notice and opportunity for public 

hearing, which provides for comment by the public and includes local political 

subdivisions. Further, all regulations promulgated in Virginia are subject to the 

Administrative Process Act (Code of Virginia, Title 2.2, Administration of 

Government, Chapter 40). Regulations promulgated by the State Air Pollution 

Control Board are also governed by 9VAC5 Chapter 5, Public Participation 

Guidelines. 

Virginia’s SIP also provides opportunity for consultation with federal land 

managers. Article 8 (Permits for Major Stationary Sources and Major 

Modifications Locating in Prevention of Significant Deterioration Areas) of Part II 

of 9VAC5 Chapter 80 (Permits for Stationary Sources) specifically provides for 

consultation with federal land managers in 9VAC5-80-1765 (Sources affecting 

federal class I areas – additional requirements). The Regional Haze SIP, to 

which EPA granted limited approval on June 13, 2012 (77 FR 35287), committed

Virginia to consultation processes with federal land managers on the submittal of 

the Regional Haze mid-course review. 

During attainment and maintenance plan development, lead planning 

organizations (LPOs) are organized as the forum for consultation and 

cooperative air quality planning decision making. LPOs are the organizations 

certified by the state as being responsible for the preparation of control strategy 

implementation plan revisions for nonattainment areas under § 174 of the Clean 

Air Act. The organizations include elected officials of local governments in the 

affected nonattainment area, and representatives of DEQ, the Virginia 

Department of Transportation (VDOT), the metropolitan planning organizations 

(MPOs) for the affected area, and other agencies and organizations that have 

responsibilities for developing, submitting, or implementing any of the plan 

revisions. All LPO documentation is submitted with each plan for the pertinent 

jurisdiction. Virginia’s plan submittals specify the organizations responsible for 

implementing and enforcing the plans.

Consultation for conformity purposes is governed by 9VAC5 -151 (Regulation for 

Transportation Conformity). The Commonwealth submitted this regulation as a 

SIP revision on May 7, 2007. All SIP revisions undergo public notice and 

hearing, which provides for comment by the public including local political 

subdivisions. Further, the Commonwealth’s Administrative Process Act (Code of 

Virginia § 2.2-4000 et seq.) requires that all regulations be provided a variety of 

public comment opportunities.
10

Therefore, the Commonwealth’s public participation requirements and 

procedures fulfill the requirements of the § 121 consultation process.

Section 127: Air quality data from Virginia’s monitoring network are available to 

the public on the Department of Environmental Quality website. As part of the § 

105 grant process, Virginia is required to submit monitoring data to the AQS in a 

timely manner. Virginia publishes an annual summary of all monitoring data on 

the DEQ website, including monitoring locations, exceedances, and violations of 

standards.

Part C: Article 8 (Permits for Major Stationary Sources and Major Modifications 

Locating in Prevention of Significant Deterioration Areas) of Part II of 9VAC5 

Chapter 80 (Permits for Stationary Sources) provides that construction and 

modification of major stationary sources will not cause or contribute to a violation 

of any NAAQS, including the 2013 PM2.5 NAAQS. EPA approved Virginia’s most 

recent PSD SIP revision on February 25, 2014 (79 FR 10377), and therefore

Virginia’s SIP-approved permit program addresses this infrastructure element for 

the 2013 PM2.5 NAAQS. Virginia’s PSD program applies to greenhouse gases 

through 9VAC5 Chapter 85 (Permits for Stationary Sources of Pollutants Subject 

to Regulation), which implements EPA’s greenhouse gas tailoring requirements. 

Section 110(a)(2)(K)(i) and (ii): "Each such plan shall provide for (i) the performance 

of such air quality modeling as the Administrator may prescribe for the purpose of 

predicting the effect on ambient air quality of any emission of any air pollutant for which 

the Administrator has established a national ambient air quality standard and (ii) the 

submission, upon request, of data related to such air quality modeling to the 

Administrator;"

Article 8, Permits for Major Stationary Sources and Major Modifications Locating

in Prevention of Significant Deterioration Areas (9VAC5-80-1605 et seq.) of 

9VAC5-80 (Permits for Stationary Sources) contains requirements for preconstruction and post-construction monitoring and modeling. 9VAC5-80-1715 

(Source impact analysis), 9VAC5-80-1725 (Air quality models) and 9VAC5-80-

1735 (Air quality analysis) provide detail on modeling requirements. This data is 

routinely provided to EPA upon request. 

Article 8 is included as part of the Virginia SIP as noted in 40 CFR 52.2420. 

Regional air quality modeling inputs and results have been provided in numerous 

SIP submittals. Virginia is a partner in multiple regional planning organizations 

and provides regional air quality modeling support to states in northeast, midAtlantic, and southeast planning organizations. Virginia will continue to share 

expertise and help create regional air quality models so long as the 

Commonwealth’s goals and resources allow.

Section 110(a)(2)(L)(i) and (ii): "Each such plan shall require the owner or operator of 

each major stationary source to pay to the permitting authority, as a condition of any 

permit required under this Act, a fee sufficient to cover (i) the reasonable costs of 
11

reviewing and acting upon any application for such a permit, and (ii) if the owner or 

operator receives a permit for such source, the reasonable costs of implementing and 

enforcing the terms and conditions of any such permit (not including any court costs or 

other costs associated with any enforcement action), until such fee requirement is 

superseded with respect to such sources by the Administrator’s approval of a fee 

program under title V;"

These requirements are located in Article 2, Permit Program Fees for Stationary 

Sources (9VAC5-80-310 et seq.) of 9VAC5-80 (Permits for Stationary Sources). 

These regulations are part of Virginia’s federally approved Title V program and 

are codified in Appendix A of 40 CFR Part 70, Approval Status of State and Local 

Operating Permits Programs.

Section 110(a)(2)(M): "Each such plan shall provide for consultation and participation 

by local political subdivisions affected by the plan;"

During attainment and maintenance plan development, LPOs are organized as 

the forum for consultation and cooperative air quality planning decision making. 

All LPO documentation is submitted with each plan for the pertinent jurisdiction. 

Consultation in matters of transportation planning for conformity purposes is 

required under 9VAC5-151 (Regulation for Transportation Conformity).

All SIP revisions undergo public notice and opportunity for public hearing, which 

provides for comment by the public and includes local political subdivisions. 

Further, all regulations promulgated in Virginia are subject to the Administrative 

Process Act (Code of Virginia, Title 2.2, Administration of Government, Chapter 

40). Regulations promulgated by the State Air Pollution Control Board are 

governed by 9VAC5 Chapter 5, Public Participation Guidelines. Consultation 

with affected localities for transportation conformity purposes is regulated by 

9VAC5 Chapter 151 (Regulation for Transportation Conformity). Additionally, the 

Code of Virginia under § 10.1-1307A requires advising, consulting, and 

cooperating with all agencies of the Commonwealth, political subdivisions, 

private industries, and any other affected groups when developing programs to 

improve or maintain air quality. The Commonwealth’s public participation 

requirements and procedures fulfill the requirements for consultation with local 

political subdivisions affected by the SIP. 

The Commonwealth’s public participation requirements and procedures fulfill the 

requirements for consultation with local political subdivisions affected by the SIP.

PUBLIC PARTICIPATION RECORD

As required by 40 CFR 51.102(e), the complete record of the public comment period, 

along with the text of the written comments, is located at the Air Division of the 

Department of Environmental Quality (DEQ). The department contact to access this 

information is the Director, Air Division.

As required by Section 2.1(h) of Appendix V of 40 CFR Part 51, below is a summary of 

the comments received and responses thereto. Included is a brief statement of the 

subject, the identification of the commenter, the summary of the comment and the 

response (analysis and action taken). Each issue is discussed in light of all of the 

comments received that affect that issue. All comments have been reviewed and 

responses developed based on an evaluation of the issues raised in consideration of 

the overall goals and objectives of the air quality program and the intended purpose of 

the document under review.

1. SUBJECT: Transport

COMMENTER: U.S. EPA Region III

TEXT: For § 110(a)(2)(D)(i)(I), Virginia states, "Since EPA has not yet quantified 

Virginia's obligation, if any, regarding the 2013 PM2.5 NAAQS, this submittal does not 

contain information regarding §110(a)(2)(D)(i)(I)." Due to the Supreme Court's April

2014 decision in EME Homer City, states such as Virginia are required to submit a SIP 

revision addressing § 110(a)(2)(D)(i)(I) independent of EPA's action finding significant 

contribution or interference with maintenance. See EPA v. EME Homer City Generation, 

L.P., 134 S. Ct. 1584.

RESPONSE: Virginia awaits further guidance from EPA before proceeding on this 

requirement. For the purposes of this submittal, this provision will not be included at 

this time as part of the SIP in order for the remainder of the submittal to be approved. 

Virginia intends to submit appropriate information for § 110(a)(2)(D)(i)(I) after EPA 

provides such guidance.

2. SUBJECT: Transport

COMMENTER: U.S. EPA Region III

TEXT: In § 110(a)(2)(D)(i)(II), Virginia states:

On October 4, 2010, Virginia submitted a Regional Haze SIP revision to meet the regulatory 
2

requirements of Subpart P of 40 CFR Part 51 and statutory requirements set forth at CAA §§ 

169A and 169B. EPA granted limited approval of this SIP revision on June 13, 2012 (77 FR 

35287). This Regional Haze SIP revision satisfies Virginia's obligations regarding 

§110(a)(2)(D)(i)(II) ... Additionally, the Clean Air Interstate Rule is an enforceable portion of 

Virginia's SIP under 9VAC5-140 ... and these requirements will help ensure that Virginia electrical 

generating unit emissions will not interfere with neighboring states' reasonable progress toward 

visibility improvement in Class I areas.

Due to the Supreme Court's April 2014 decision in EME Homer City, the Clean Air

Interstate Rule (CAIR) was vacated and replaced with the Cross-State Air Pollution Rule

(CSAPR). Therefore, EPA will not be able to approve the visibility portion of element

(D)(i)(II) of Virginia's infrastructure SIP revision due to the fact that, (1) Virginia's 

Regional Haze SIP incorrectly relies on CAIR for reductions from electric generating 

units (EGUs), and (2) the 2013 PM2.5 infrastructure SIP revision also relies on 

reductions from CAIR for EGUs in order to meet the visibility requirements of CAA §

110(a)(2)(D)(i)(II).

RESPONSE: A formal commitment to meet the federal CSAPR rule as well as a 

demonstration that CSAPR budgets are generally at least as stringent as those for 

CAIR have been submitted to EPA on July 16, 2015. Therefore, the July 2015 submittal 

rectifies the Regional Haze SIP in this regard. The final 2013 PM2.5 infrastructure SIP 

has been revised to reference the July 2015 submittal.

3. SUBJECT: Transport

COMMENTER: U.S. EPA Region III

TEXT: For § 110(a)(2)(A) and (C), Virginia includes 9VAC5 Chapter 140 (Emissions 

Trading) as an enforceable control measure that has been approved into the Virginia 

SIP. Due to the Supreme Court's April 2014 decision in EME Homer City and the 

subsequent decision by the Third Circuit, CAIR was replaced with CSAPR and 

implementation of CSAPR began on January 1, 2015. Because of these recent 

developments, Virginia's emissions trading regulations approved under CAIR are no 

longer enforceable and should not be included as an enforceable control measure.

RESPONSE: References to Chapter 140 (Emissions Trading) have been removed 

from the SIP.
