Associate Director, Office of Air Program Planning
**A. INTRODUCTION**  The Environmental Protection Agency (EPA) is taking action on the State of Mary land State Implementation Plan (SIP) revision submitted by the Mary land Department of the Environment (MDE) to meet the Clean Air Act (CAA) section 110(a)(2) requirements for the revised 2008 Ozone N ational A mbient A ir Q uality S tandard (NAAQS)
. **B. BACKGROUND 2008**  **Ozone NAAQS**  On March 27, 2008, EPA promulgated a revised NAAQS for ozone based on 8

- hour average concentrations. EPA revised the level of the 8

- hour ozone NAAQS to 0.075 parts per million (ppm). Pursuant to section 110(a) of the CAA, states are req uired to submit SI Ps to provide for the implementation, maintenance, and enforcement of a new or revised NAAQS within three ye ars following the promulgation of such NAAQS, or within a shorter period as EPA may prescribe. More specifically , section 110(a)( 1) provides the procedural and timing requirements for SI Ps. Section 110(a)(2) lists specific elements that states must meet for ‘‘infrastructure’’ SI P requirements related to a newly established or revised NAAQS. These requirements include basic SI P ele ments such as requirements for monitoring, basic program requirements and legal authority that are designed to assure attainment and maintenance of the NAAQS. Section 110(a) imposes the obligation upon states to make a SI P submission to EPA for a new or r evised NAAQS, but the contents of that submission may vary depending upon the facts and circumstances. In particular, the data and anal yt ical tools available at the time the state develops2

and submits the SI P for a new or revised NAAQS affects the content of the submission. The contents of such SI P submissions may also vary depending upon what provisions the state’s existing SI P alread y contains. In the case of the 2008 8

- hour ozone NAAQS, states ty picall y have met the basic program elements required in section 110(a)(2) through earlier SIP submissions in connection with the 1997 8

- hour ozone NAAQS. **C. EPA REQUIREMENTS** As discussed above, for the 2008 ozone NAAQS, states must provide SI P submissions which identify authorities and/ or provide certification of how the existing SI P contain s provisions addressing relevant infrastructure SI P elements
. **D. STATE’S SUBMITTAL** On December 27 , 2012, Maryland provided a submittal to satisfy the requirements of section 110(a)(2) of the CAA for the 2008 ozone NAAQS. This submittal addressed the following infrastructure elements, or portions thereof, that EPA is proposing to approve: section 110 (a)(2)(A), (B), (C), (D), (E), (F), (G), (H), (J), (K), (L), and (M) of the CAA. EPA is acting on all elements except, 110(a)(2)(D)(i)(I) on which it will take separate action, and 110(a)(2)(I) and portions of elements that pertain to Part D nonattainment area requirements.
**E. EVALUATION OF STATE SUBMITTAL 1. Section 110(a)(2)(A)**  According to the SIP submittal of December 27 , 20 12 and Mary land’s current SI P, enforceable emission limitations and other control measures are found in portions of the Maryland SI P including, but not limited to, COMAR 26.11 which addresses air quality . Although the SIP mentions a consent decree with Mirant, a cop y was not provided with the SIP submittal and the emission limits in the Consent Decree are alread y federally enforceable. Therefore EPA believes this was simply

provided as a reference and interprets this mention for reference purposes onl y. Maryland also references an 8

- hour ozone SI P submittal. All approved EPA SI P submittals including those for ozone can be found in 40 CFR 52.1070. Maryland s ource specific rules are listed in 40 CFR 52. 1070(d) and approved plans are in 40 CFR 52.1070(e). Based upon EP A ’s review of the infrastructure submittal and Mary land’s current SI P, EPA finds that Maryland has met its obligations pursuant to 110(a)(2)(A) of the CAA
. EPA does not consider SIP requirements triggered by the nonattainment area mandates in part D of Title Iof the CAA to be governed by the submission deadline of section 110(a)(1). Nevertheless, the State may have included some previous EPA approved SIP provisions originall y submitted in response to part D in its submission documenting i ts compliance with the requirements of sections 110(a)(1) and (2) of the CAA. For the purposes of this action, EPA has reviewed the above identified Mary land submittals, including an y rules originall y submitted in response to part D, or references thereto , solely for the purposes of determining whether such3

submittals support a finding that the state has met the basic infrastructure requirements under section 110(a)(2). In this action, EPA is not proposing to approve or disapprove an y existing Maryland provisions with regard to excess emissions during startup, shutdown, and malfunction (SSM) of operations at a facility . EPA believes that a number of states have SSM provisions which are contrary to the CAA and existing EPA guidance (August 11, 1999 Steve n Herman and Robert Perciasepe Guidance Memorandum, “State Implementation Plans: Policy Regarding Excess Emissions During Malfunctions, Startup, and Shutdown”), and the Agency is addressing such state regulations in a separate rulemaking. See 78 FR 12460. Inthe meantime, EPA encourages any state having a deficient SSM provision which is contrary to the CAA and EPA guidance to take steps to correct it as soon as possible. Also in this action, EPA is not proposing to approve or disapprove an y existing Maryl and rules with regard to director’s discretion or variance provisions. EPA believes that a number of states have such provisions which are contrary to the CAA and existing EPA guidance (52 FR 45109, November 1987), and the Agency is addressing such state regulations in a separate rulemaking. See 78 FR 12460. In the meantime, EPA encourages any state having director’s discretion or variance provisions which are contrary to the CAA and EPA guidance to take steps to correct the deficiency

as soon as possible
. **2. Section 110(a)(2)(B)** According to the submittal , M ar yl and’s authority to monitor can be found in §§2
- 103(b)(2) and 2
- 301 (a)(1), Environment Article, Annotated Code of Mary land . Also , due to a recentl y approved SIP revision , Maryland ’ s more specif ic monitoring methods are found in SI P approved COMAR 26.11.04.0 2 (specify ing methods of measuring ambient air quality levels shall be those specified in 40 C.F.R. Parts 50, 53 and 58) and not COMAR 26.11.04.03 which was identified in their infrastructure submittal as the COMAR specifying methods of measuring ambient air quality levels
. Maryland operates and maintains a network of ambient air monitors throughout the State. All ambient air monitors in the Mary land network that are used to determine co mpliance with the NAAQS have been designated b y EPA as either Reference or Equivalent monitors. All ambient air monitors in the Maryland network are subjected to the Quality Assurance requirements of 40 CFR Part 58 Appendix A. Inaddition, all samplers are located at sites that have met the minimum siting requirements of Part 58, Appendix E. In Mary land, no specific statutory authorit y is necessary

to authorize data analy sis or the submission of such data to EPA. Federal grant requirements establish the obligation to provide d ata to EPA. In order to keep EPA informed of changes to the sampling network, MDE 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. Pursuant to 40 CFR Part 58, Subpart B, Section 58.10, MDE sends the EPA Regional Administrator an Annual Monitoring Network Plan for approval that details any modifications to the network. This plan also provides a4

description of each modification, the reason for each modification, and any other information relevant to the modifications. Section 58.10 also requires MDE (beginning July 1, 2010) to perform an d submit to the EPA Regional Administrator an assessment of the Maryland ambient air monitoring network every five years to determine, at a minimum, if the network meets the monitoring objectives defined in 40 C.F.R., Part 58, Appendix D
. Th e docket for this proposed rulemaking contains the most recent approval from EPA of the current monitoring network plan
. Mary land has and will continue to submit data to EPA's Air Quality System (AQS). MDE collects and reports to EPA ambient air quality data for ozone as well as other NAAQS. The reports comply with the federal requirements of 40 CFR 58.35. As necessary, the submitted data is reviewed, edited, validated, and entered into the EPA AQS for updating pursuant to prescribed AQS procedures. MDE analyzes such air quality

data to determine attainment status or progress. Based upon EPA’s review of the submittal and Maryland’s current SIP , EPA finds that Mary land has met its obligations pursuant to 110(a)(2)(B) of the CAA
. **3. Section 110(a)(2)(C)** Maryland’s statutory

provisions for the enforcement of the provisions described in §110(a)(2)(A) of the C AA are found at §§2

- 601

—2
- 614 of the Environment Article of the Annotated Code of Maryland. Specific enforcement provisions for the items under section 11 0(a)(2)(A), above, may also be found in Mary land’s SI P at 40 CFR 52.1070. T he Mary land SIP includes a SI P approved program to provide for regulation of modification and construction of stationary sources within the S tate, including Mary land’s permitting program for part C of Title I of the CAA.

 Maryland's permit to construct and Prevention of Significant Deterioration ( PSD ) approval program requirements are found in COMAR 26.11.02, which also contains enforcement provisions for violations of permits to construct, PSD approvals, and operating permits.

 COMAR 26.11.06.14 contains pre

- construction permitting requirements for P SD sources and was last approved by EPA on August 2, 2012 (77 FR 45949) to implement requirements of EPA’s final PSD and Title V Greenhouse Gas Tailoring Rule, which was published in the Federal Register on June 3, 2010 (75 FR 31514).

 COMAR 20.79, “Appli cations Concerning the Construction or Modification of Generating Stations and Overhead Transmission Lines,” particularl y the EPA SI P
- approved portions of this chapter, regulate construction and modification of electric generating stations, including consi deration of related air qualit y impacts.5  The following SIP

- approved portions of the Public Utilities Article, Annotated Code of Mary land also establish requirements for construction and modification of electric generating stations: o § 7
- 205, Electric companies

– Modification of power plant o § 7
- 207, Generating stations or transmission lines

-- General certification procedure o § 7
- 208, Generating stations or transmission lines

-- Joint construction of station and associated lines

 Maryland’s Title V permits ar e under COMAR 26.11.03. This chapter of COMAR also includes provisions providing for enforcement of Title V permits (COMAR 26.11.03.21, “General Part 70 Permits”). Note that COMAR 26.11.03 is not part of Mary land’s EPA approved SIP and is mentioned here just for reference purposes. Based upon EPA’s review of the submittal and Maryland’s current SIP , EPA finds that Mary land has met its obligations pursuant to 110(a)(2)( C) of the CAA
. **4. Section 110(a)(2)(D**  **) Section 110(a)(2)(D)(i)(I)**  In accordance with the decision of the U.S. Court of Appeals for the D istrict of Columbia , the EPA at this time is not treating the 110(a)(2)(D)(i)(I) SIP submission from the State of Mary land as a required SI P submission. See EME Homer City Generation, L.P. v. EPA, 696 F .3d 7 (D.C. Cir. 2012), cert. granted, 133 U.S. 2857 (2013)
. However, even if the submission is not considered to be “required,” the EPA must act on the 110(a)(2)(D)(i)(I) SIP submission from Mary land because section 110(k)(2) of the CAA requires the EPA to act on all SI P submissions. Unless the EME Homer City decision is reversed or otherwise modified by the Supreme Court, states are not required to submit 110(a)(2)(D)(i)(I) SI Ps until the EPA has qu antified their obligations under that section. The portions of the SI P submission relating to 110(a)(2)(D)(i)(II) and 110(a)(2)(D)(ii), in contrast, are required. In this notice, EPA is only proposing to act on 110(a)(2)(D)(i)(II) and 110(a)(2)(D) ( ii). EPA will take separate action on 110(a)(2)(D)(i)(I) of Maryland’s 110(a)(2)(D) submittal. All areas of Mary land are covered by a SIP approved PSD program as discussed above for section 110(a)(2)(C) , and Mary land does not have any Class I Areas. **Section 110(a)(2)(D)(i)(II)** For al l areas of Mary land , a SI P approved PSD program is in place. The permitting program is codified at 40 CFR 52.1070 and is discussed in detail above for 110(a)(2)(C) of the CAA

- 207, and 7
- 208 Requirements for construction and modification of generating stations EPA is proposing to approve the infrastructure SIP submission with respect to 110(a)(2)(D)(i)(II) prong 3 ( for the p art C of Title Iof the CAA permit program ) because Maryland’s SI P contains an approved PSD program. Prong 4 of section 110(a)(2)(D)(i) requires that SIPs include provisions prohibiting any source or other ty pe of emissions activity

in one state from interfering with measures to protect visibility required to be included in another state’s SIP
. In describing how its submission s meet th is requirement, the State referred to its February 13, 2012 Regional Haze SI P submittal which was fully approved by

EPA on July

6, 2012 (77 FR 39938). Thus, EPA is proposing to approve the infrastructure SI P submission s with respect to 110(a)(2)(D)(i)(II ) prong 4 because Mary land’s approved regional haze SI P adequatel y prevents sources in Mary land from interfering with measures adopted by other states to protect visibility during the first planning period. Based upon EPA’s review of the submitta l , and the M ar yl and SI P , EPA finds that Maryland has met its obligations pursuant to 110(a)(2)( D ) (i)(II). **Section 110(a)(2)(D)(ii)** As discussed above for 110(a)(2)(C) and (D)(i)(II), Maryland has a SI P approved permitting program for part C of Title Iof the CAA. Therefore, Mary land has demonstrated that it has met its obligations pursuant to CAA section 126(a). In addition, Mary lan d has no currentl y pending obligations pursuant to CAA Section 126(b), and has made the necessary submittals through its infrastructure SI P submittal to demonstrate that the State has adequate provisions insuring future compliance with the requirements of sections 126 and 115 of the CAA. Therefore, EPA finds Maryland’s infrastructure SI P meets the requirements of CAA section 110(a)(2)(D)(ii) of the CAA
.7

**5 . Section 110(a)(2)(E)**  According to the submittal, Mary land receives funds via the 105 grant program. Mary land also has a Clean Air Fund (Environment Article, §2

- 107, Annotated Code of Maryland) composed of funds collected from application fees, permit fees, renewal fees, and civil or administrative penalties or fines which support air quality ac tivities. Mary land's Clean Air Fund may be used for (1) identify ing, monitoring, and regulating air pollution in the State, including program development of these activities as provided in the State budget; and (2) providing grants to local governments to supplement funding for programs conducted by local governments that are consistent with the Mary land program. Mary land has s everal o ther authorities to implement the Maryland SIP identified below . EPA previously

identified similar authorities for imp lementing the Maryland SIP in EPA’s TSD supporting its rulemaking proposing approval of the Maryland NO 2 infrastructure SIP submittal . The TSD is available in the docket for that rulemaking at www.regulations.gov, Docket ID Number EPA

- 302 (b)

- (d), Annotated Code of Maryland. EPA finds Maryland has adequate resources to implement the SIP pursuant to 110(a)(2)(E)(i). On December 6, 2013 , EPA took a direct final action to approve a SIP submittal for Maryland that meets section 128 of the CAA and therefore E(ii) for this ozone NAAQS regarding compliance with state boards as described in section 128 of the CAA. A detailed rationale for the a pproval was set forth in the direct final rule (78 FR 73472) which was effective on February 4, 2014. Therefore, EPA finds that Maryland’s SIP adequatel y addresses 110(a)(2)( E ) (ii).8

Finally , as explained in the SI P submittal, Mary land does not rel y on any local or regional government, agency , or instrumentality for implementing the SI P. EPA finds that Maryland’s SI P submittal and existing SIP adequatel y address 110(a)(2)( E ) (ii i ). Therefore, b ased upon EPA’s review of the SI P submitta l, and Mary land’s SI P, EPA finds that Maryland has met its obligations pursuant to all portions of 110(a)(2)(E)
. **6 . Section 110(a)(2)(F)**  According to Maryl and ’s submittal, the two main statutory provisions which pro vide authorit y for source emissions testing and mon i t o ring are §2
- 103(b)(1) and § 2
- 301(a)(1) , Environment Article , Annotated Code of Mary land. In addition , SI P approved regulations require installation and mai nten ance of monitoring equipment , including but not limited to COMAR 26.11.01.04, “Testing & Monitoring” and COMAR 26.11.01
. 10 Continu ous Emissions Monitoring ( CEMs) Requirements
. The submittal references COMAR 26.11.01.11 as well as Maryland’s T itle V program ( COMAR 26.11.03 ) which contain requirements related to source testing/monitoring
. These are provided for reference. Several Mary l and SI P approved regulations includ e stationary source monitoring and emission reporting , including : COMAR 26.11.01.04 “Testing and Monitoring” ; COMAR 26.11.01.05 “Records and Information ” ; COMAR 26.11.01.05
- 1 “Emission Statements” ; COMAR 26.11.01.07 “Malfunctio n s and other Temporary Increase in Emissions ; COMAR 26.11.01.10 Continuous Emissions Monitoring ; COMAR 26.11.27.05 “ Emissions Limitations for Power Plants, Monitoring and Reporting Requirements ” ; and COMAR 26.11.03.03, “Information Required as Part of Application for a Part 7 0 Permit.” However COMAR 26.11.03.03 is not included in Mary land’s SIP

- approved regulations but is included here for reference. These regulations address requirements in 40 CFR Part 51.211 Emissions Reports and record keeping an d 40 CFR 51.212 and 40 CFR Part 51 Subpart A , Air Em i ssions Report i ng Requirements
. In addition , §2
- 103(b ) , Environment Article , Annotated Code of Mary land provide s statutory a uthority over emissions, ambient air quality and air quality

monitoring. COMAR 26.11.01.05 requires source s to mai ntain records to de t ermine compliance with emission standards and COMAR 26.11.01.04(B)(4) requires all information received under this provis ion to be provided for public inspection. Criteria pollutant emissions information relate d data is available to the public for inspection in accordance with 40 CFR 51.116 ( data availability)
. Based upon EPA’s review of the submittal, the Maryland SI P , and Mary land’s Annotated Code , EPA finds that Maryland has met its obligations pursuant to 110(a)(2)(F) of the CAA
. **7 . Section 110(a)(2)(G)**  According to the submittal referenced above, Mary land can address air pollution emergencies as authorized by §2
- 105, Environment Article, Annotated Code of Maryland , and the authority to adopt regulations that establish standards and procedures to be followed whenever pollution of the air reaches an emergency condition are found in §2
- 301(a) (2), Environment Arti cle, Annotated Code of Mary land. Mary land’s SIP under 40 CFR 52.1070(c) includes Air Pollution Episode System9

( COMAR 26.11.05 )
. Additionally , Mary land’s authority regarding accidental or other releases that are not authorized by statute, regulation or pe rmit or occur in conjunction with violations of existing regulatory

requirements can be found in §2
- 604 (Administrative corrective order authority) , Environment Article, Annotated Code of Maryland and § 2

- 609 (a) (Civil injunctive authority), Environment Article, Annotated Code of Mary land. Ba sed upon EPA’s review of the submittal and Maryland’s SIP , EPA finds that Maryland has met its obligations pursuant to 110(a)(2)(G) of the CAA
. **8 . Section 110(a)(2)(H)**  According to the submittal referenced above , Maryland’s SI P is essentially a compilation of regulations, source

- specific provisions and plans to meet the NAAQS
. The authority to develop or revise a SIP is based on the authority to adopt new regulations and revise existing regulations to meet the NAAQS (§2

- 301(a)(1) , Environment Article, Annotated Code of Maryland. Nothing in Maryland’s statutory or regulatory authority prohibits the State from revising the SIP when the NAAQS are revised by EPA. Th is submission provide s EPA with adequate assurances that Mary land will review and revise its SI P from time to time as may be necessary

to take account of revisions or the availability of improved or more expeditious methods of attaining such standards. EPA also finds these pro visions provide adequate assurances that Mary land can revise its SI P whenever the Administrator finds, on the basis of information available to the Administrator, that the plan is substantially

inadequate to attain the NAAQS or to otherwise compl y with any additional requirements established under the CAA. Based upon EPA’s review of the submittal and , Maryland’s SIP, EPA finds that Maryland has met its obligations pursuant to 110(a)(2)(H) of the CAA
. **9 . Section 110(a)(2)(J)**  According to Maryland’s SI P submittal mentioned above and the Mary land SI P , Mary land meets the requirements of Section 121 (relating to consultation). All Mary land SIP revisions undergo public notice and hearing, which provides for comment by the public and local political subd ivisions, including but not limited to, MWAQ (Metropolitan Washington Air Quality Committ ee ), IAQC (Interstate Air Qualit y Council), the Baltimore Regional Transportation Board, the National Capital Transportation Planning Board, the Wilmington Area Plann ing Council, and Hagerstown/Eastern Panhandle Metropolitan Planning Organization. Public hearings on proposed Mary land regulations are held in accordance with EPA requirements under 40 CFR 51.102. The Air Quality Control Advisory

Council also follows a c onsultation process (§§ 2

- 201
- 206 Environment Article, Annotated Code of Mary land)
. Public hearings on proposed Maryland regulations are held in accordance with Section 2

- 303(b) of the Environment Article of the Annotated Code of Maryland which requires that a public hearing be held before adopting air quality regulations. Inaddition, Subtitle 1 of Title 10, State Government Article of the Annotated Code of Maryland provides administrative procedure requirements for adopting or modify ing regulations and these procedures include public notification and participation10

requirements. Maryland also addresses the consultation requirements through the public notification statutory

provisions discussed below. Section 127 (relating to public notification). As mentioned above, Section 2

- 303(b) of the Environment Article of the Annotated Code of Maryland requires that public hearings be held before Mary land adopts air quality regulations. In addition, Subtitle 1 of Title 10, State Government Article of the Annotated Code of Mary land sets forth the administrative procedures for Mary land to adopt or modify regulations. In addition, EPA SI P approved regulations and statutory provisions in which public notification and hearings are addressed are listed below: COMAR Subtitle/Chapter Description 26.11.02.11 “Procedures for Obtaining Permits to Construct Certain Significant Sources” 26.11.02.12 “Procedures for Obtaining Approvals of PSD Sources and NSR Sources, Permit s to Construct, Permit to Construct MACT Determinations On a Case

a These provision s are for reference purposes onl y and are not included in the Maryland SI P. Part C (relating to visibility protection). With regard to the visibility pro tection aspect of 110(a)(2)(J), EPA recognizes that states are subject to visibility and regional haze program requirements under part C of Title Iof the CAA (which includes sections 169A and 169B of the CAA). In the event of the establishment of a new NAAQS, however, the visibility and regional haze program requirements under part C of Title I of the CAA do not change. Thus, EPA finds that there are no applicable visibility obligations under part C “triggered” under sect ion 110(a)(2)(J) when a new NAAQS becomes effective. Mary land has an approved regional haze SI P which addresses submitted SI P revisions to satisfy the requirements of CAA Sections 169A and 169B, as discussed above for section 110(a)(2)(D)(i)(II) of the CA A
. For the purposes of PSD, Maryland incorporates the federal regulations by reference. For further discussion on how Maryland meets the requirements of part C of Title I of the CAA with respect to PSD, see Section 110(a)(2)(C) and Section 110(a)(2)(D) (i)(II)(prong 3) above. EPA finds Maryland’s infrastructure SI P meets the requirements of CAA section 110(a)(2)(J) relating to consultation, public notification, and visibility protection requirements. Based upon EPA’s review of the above submittal , Mar yl and’s SI P, and the Annotated Code of Maryland, EPA finds that Mary land has met its obligations pursuant to CAA Section 110(a)(2)(J)
. **1 0**  **. Section 110(a)(2)(K)** According to the subm i ttal, Mary land has authority under §2
- 302 of the Environment Article, Annotated Code of Maryland, to do modeling since inherent in the obligation to meet the NAAQS is the authority

for the Department to perform modeling as required under the CAA to demonstrate attainment. In addition, Mary land has a SIP approved PSD program under 40 CFR 52.1070 which includes modeling and Mary land submits air quality modeling data as part of Maryland’s relevant SIP submissions in accordance with the Clean Air Act and through federal grant commitments. For the authority

to perform air quality

modeling and the submission of relevant data , see S ections 2

- 103 and 2

- 302 of the Environment Article of the Annotated Code of Mary land and S ections 7

- 205, 7
- 207, 7
- 207.1, and 7

- 208 of the Public Utilities Article o f the Code which is in the approved Mary land SIP . SI P approved portions of COMAR 20.79.01, 20.79.02, and 20.79.03 establish requirements for the calculation of increases in air emissions related to modifications of facilities at power plants and require m odeling
. In addition, COMAR 20.79.03.02 which is in the Maryland SI P establishes requirements for applications regarding construction and modification of generating stations to demonstrate compliance with environmental restrictions. This includes provid ing information to show the impact on air quality
