## 1 ENCLOSURE 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, non re gulatory 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 ne cessary, 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) i n the CAA relevant to the 2013 f ine p articulate ( PM 2.5 

## ) 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 ad dressed 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. T herefore, 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 prot ection 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 PM 2.5 

## on July 18, 1997 (62 FR 38652). Prior to the 1997 PM 2.5 

## NAAQS, regulated particle pollution consisted of Total Suspended Particulate (TSP) or particulate with a diameter of less than 10 angstroms ( PM 10 

## ). The 1997 PM 2.5

## 2 NAAQS was the first NAAQS to regulate particles with a diameter of less than 2.5 angstroms. The 1997 PM 2.5 

## NAAQS set a 24 - hour standard of 65 μg/m 3 

## and an annual standard of 15.0 μg/m 3 

## . On October 17, 2006 (71 FR 61144), EPA finalized a new PM 2.5 

## NAAQS, which reduced the 24 - hour standard to 35 μg/m 3 

## while leaving the annual standard at 15.0 μg /m 3 

## . EPA further strengthened protections for PM 2.5 

## pollution on January 15, 2013 (78 FR 3086). The 2013 PM 2.5 

## NAAQS reduced the primary health standard for PM 2.5 

## to 12 .0 μg/m 3 

## and left the remaining standards in place. Governors may submit recommenda tions for nonattainment areas within one year of a standard being promulgated. Virginia submitted a designation recommen d ation letter to EPA on December 13, 2013 , in which Virgin i a 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 PM 2.5 

## NAAQS (80 FR 2206). EPA designated all of Virginia as attainment for the 2013 PM 2.5 

## 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 timetable s 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 d a ta on ambient air quality, and (ii) upon request, make such data available to the Administrator; " Virginia maintains and operates a multi - station PM 2.5 

## network to measure ambient concentrations within the Commonwealth for comparison to the NAAQS . All data is measured using EPA - approved methods as either r eference or e quivalent monitors ; all monitors are subject to the quality assurance requirements of 40 CFR Part 58 ; and all samplers are locate d 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 approve d t he most recent summary , which was submitted for 201 4 . 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, e t c . , " 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 whi ch 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 p roperty... 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 st andards are achieved, includ ing 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 fo r 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 Ma jor 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 con tribute to a violation of any NAAQS, including the 201 3 PM 2.5 

## 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 address es this infrastructure element for th e 2013 PM 2.5 

## 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 enforceme nt 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 provisi on s 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 implementati on 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 i n 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 PM 2.5 

## 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 PM 2.5 

## 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 th e 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 Chapte r 80 (Permits for Major Stationary Sources). On October 4, 2010, Virginia submitted a Regional Haze SIP r evision 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 Retrofi t 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. T hese requirements will help ensure that Virginia EGU emissions will not interfere with

## 5 neighboring states’ reasonable progress toward visibility improvement in Class I areas. Th e 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 PM 2.5 

## 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 sourc e to notify neighboring states of potential impacts from that source. Major stationary sources of PM 2.5 

## 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 St ationary 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 regu lations 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 i s not subject to any pending actions or petitions regarding PM 2.5 

## 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 § 11 5 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 pl an. 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 nece ssary 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 schedu les. 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 p rovided 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 - 1 322. 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 PM 2.5 

## requirements. Should EPA determine that Virginia lacks adequate personnel to ca rry 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 requir ements 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 o f the members of the board represent the public interest and do not d erive 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 f or disclosure of p otential 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 provi sion, 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 PM 2.5 

## 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 emissions related data from such sources ; " Requirements for periodic reports on the nature and amounts of emissions and emissio ns - 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 S tationary 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 S tationary 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 Requirement s . Should requirements for data submittals change as a result of the 20 13 PM 2.5 

## 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 an y emission limitations or standards established pursuant to this Act, which reports shall be available at reasonabl e 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 1 3, Air Pollution Control Board , authorize s the board to de clare a state of emergency and issue

## 8 without hearing an emergency special order directing the owner to cease such pollution immediately u pon finding that any owner is unreasonably affecting the public health, safety or welfare; the health of animal or plan t life; or property . Section 10.1 - 1309.1 authorize s 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 PM 2.5 

## level greater than 140.4 μg/m 3 

## since 200 6 (s ee 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 PM 2.5 

## 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 prima ry or secondary ambient air quality standard or the availability of improved or more expeditious met hods 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 Pollu tion 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, § 1 0.1 - 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 Adm inistrator 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 requirement s establishe d 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 implemen tation 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 requireme nts 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, Administ ration 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 manag ers. 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 lan d 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), commit ted Virginia to consultation processes with federal land ma nagers 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. LPO s 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 govern ments 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 fo r 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 plan s. Consultation for conformity purposes is governed by 9VAC5 - 151 (Regulation for Transportation Conformity). Th e Commonwealth submitted this regulation as a SIP revision on May 7, 2007. All SIP revisions undergo public notice and hearing, which provide s 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 E nvironmental 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) provide s that construction and modification of major stationary sources will not cause or contribute to a violation of any NAAQS, including the 201 3 PM 2.5 

## NAAQS . EPA approved Virginia’s most recent PSD SIP revision on February 25, 2014 (79 FR 10377), and therefo re Virginia’s SIP - approved permit program addresses this infrastructure element for the 2013 PM 2.5 

## NAAQS. Virginia’s PSD program applies to greenhouse gases through 9VAC5 Chapter 85 (Permits for Stationary Sources of Pollutants Subject to Regulation), whi ch implements EPA’s greenhouse g as 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 ; " Arti cle 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 pre construction 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 d ata 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 multip le regional planning organizations and provides regional air quality modeling support to states in northeast, mid Atlantic, 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 co nditions 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 Appendi x A of 40 CFR Part 70, Approval Status of S t ate 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 mai ntenance 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 transportatio n planning for conformity pur poses is required under 9VAC 5 - 151 ( Regulation for Transportation Conformity ) .

## 1 ENCLOSURE 3 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 d epartment 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 subj ect, 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 deve loped 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 § 11 0 (a)(2)(D)(i)(I), Virginia states, "Since EPA has not yet quantified Virginia's obligation, if any, regarding the 2013 PM 2.5 

## NAAQS, this submittal does not contain information regarding §110(a)(2)(D)(i)(I)." Due to the Supreme Court's April 2014 decisio n 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., 13 4 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 § 11 0 (a)(2)(D)(i)(I) after EPA provides such guidance. 2 . SUBJECT: Tr ansport 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 reg arding §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 n eighboring 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 genera ting units (EGUs), and (2) the 2013 PM 2.5 

## 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 PM 2.5 

## 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 measu re 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 o f these recent d evelopments, 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 fr om the SIP. TEMPLATES \ SIP - PLAN \ PLN03 SIP \ ASSESSMENT \ L S - SIP - 3.DOC
