**A. INTRODUCTION**  The Environmental Protection Agency (EPA) is taking action on the Commonwealth of Pennsylvania (Commonwealth) 1 State Implementation Plan (SI P) revision submitted by the Pennsylvania Department of Environmental Protection (PADEP) to meet the Clean Air Act (CAA) section 110(a)(2) requirements for the revised 2008 Lead N ational A mbient A ir Q uality S tandards (NAAQS)

. **B. BACKGROUND 2008 Lead**  **NAAQS** On October 15, 2008, EPA revised the primary and secondary

lead NAAQS from 1.5 micrograms per cubic meter (μg/m 3 ) to 0.15 μg/m 3 . Section 110(a) of the CAA requires states to submit SI Ps that provide for the implementation, maintenance, and enforcement of new or revised NAAQS within three ye ars following the promulgation of such NAAQS. Section 110(a) of the CAA imp oses the obligation upon states to make a SIP submission to EPA for a new or revised NAAQS. For the 2008 lead NAAQS, states ty picall y have met many of the basic program elements required in section 110(a)(2) of the CAA through earlier SIP submissions in c onnection with previous lead standards. Section 110(a)(2) of the CAA lists specific elements that states must meet or continue to meet in these SIP submissions. The requirements include SI P infrastructure elements such as requirements for modeling, monit oring, and emissions inventories that are designed to assure attainment and maintenance of the NAAQS. Section

1 When using the term “Commonwealth” or “Pennsylvania” in this document, these terms refer to the entire state except as specifically noted.2

110(a)(2) of the CAA infrastructure elements (A) through (M) are listed in EPA’s memorandum from Stephen D. Page, Director, Office of Air Quality Planning and Standards to the Regional Air Division Directors, Regions 1

- 10, “ Guidance on Infrastructure State Implementation Plan (S IP) Elements Required Under Sections 110(a)(1) and 110(a)(2) for the 2008 Lead (Pb) National Ambient Air Quality Standards (NAAQS) ,” October 14, 2011, (hereafter referred to as “Lead Infrastructure Guidance”).

**C. EPA REQUIREMENTS** As discussed above, for the 2008 lead NAAQS, states must provide SI P submissions, or provide certification that the existing SI P contains provis ions addressing relevant infrastructure SI P elements from sections 110(a)(2)(A) through (M) of the CAA. To help states meet this statutory requirement, EPA issued the Lead Infrastructure Guidance, which listed the basic elements that states must include i n their SI Ps.

**D. STATE’S SUBMITTAL** To satisfy the requirements of section 110(a) (1) and (2) of the CAA for the 2008 lead NAAQS , PA DEP submitted a SI P revision in accordance with the October 11 , 20 11 guidance. To satisfy the requirements of section 110(a)(1) and (2 ), PA DEP submitted the lead infrastructure SI P revision on September 2 4 , 2012 which was received on September 27, 2012

. EPA is acting on all elements except 110(a)(2)(I) , and portions of e lements that pertain to Part D nonattainment area requirements and portions of 110(a)(2)(E)

.

**E. EVALUATION OF STATE SUBMITTAL 1. Section 110(a)(2)(A)**  According to the submittal, the Commonwealth’s enforceable emission limitations and other control measures are covered in the Air Pollution Control Act (APCA) and those provisions of Pennsylvania Code Title 25, Environmental Protection, Article III, Chapte rs 121

- 145 (25 Pa. Code Chapters 121

- 145), Title 67, Chapters 175

– 177 listed in 40 CFR §52.2020(c)(1), Alleghen y County Health Department (ACHD) Regulations, Parts A through I to Articles XX and XXI listed in 40 CFR 52.2020(c)(2), Philadelphia Title 3 Ai r Management Code and Philadelphia Air Management Services ( AMS ) Regulations I, II, III, IV, V, VII, VIII, XI, and XIII listed in 40 CFR 52.2020(c)(3), and source specific provisions codified at 40 CFR 52.2020(d)(1) and (2). Based upon EPA’s review of th e submittal , EPA is proposing to determine that the Commonwealth has met its obligations pursuant to 110(a)(2)(A). 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 s ubmission deadline of section 110(a)(1). Nevertheless, the Commonwealth may have included some previous EPA

- approved SIP provisions originall y submitted in response to part D in its submission documenting its compliance with the requirements of sections 1 10(a)(1) and (2) of the CAA. For the purposes of this action, EPA has reviewed the above identified Pennsy lvania submittals, including any rules3

originall y submitted in response to part D, or references thereto, solel y for the purposes of determining whether such 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 Commonwealth provisions with regard to excess emissions during SSM of operations at a facility . Also , EPA is not proposing to approve or disapprove any existing State rules with regard to director’s discretion or variance provisions. **2. Section 110(a)(2)(B)** According to the submittal, Section 4(17) of the APCA, 35 P.S. § 4004, provides authority to “determine b y means of field studies and sampling the degree of air pollution existing in any part of the Commonwealth.” PA DEP establishes, operates and maintains a network of ambient air monitors throughout Pennsy lvania, excluding Philadelphia and Allegheny Counties. Both Philadelphia AMS and the ACHD operate their monitoring networks and collect data under Pennsylvania approved programs

. Based on the submittal, the Pennsylvania network consists only of monitors that have been designated b y EPA as either Reference or Equivalent monitors. All ambient air monitors are subjected to the Qualit y Assurance requirements of 40 CFR Part 58, Appendix A. In addition, all samplers are l ocated at sites that have met the minimum siting requirements of Part 58, Appendix E. Also according to the submittal, a s required in 40 CFR Section 58.10, an annual network design plan is required to be submitted to the EPA Regional Administrator by July 1 of each y ear. The network design document informs both EPA and the public of any planned changes to the sampling network for the next year. The annual network design plan provides a description of the current monitoring network, a reason for each change , and any other information relevant to the change. DEP provides a 30

- day

public comment period for the annual network design plan. In addition, DEP and the local air agencies provide EPA Region III with prior notification of any planned changes to the ne twork between formal network design submissions. As needed, details of these changes are communicated to and approved by EPA. The following detailed information is provided as supplemental information but specific monitor locations are not being incorpor ated into the SIP. In accordance with the original Lead Ambient Air Monitoring Requirements, promulgated November 12, 2008 (73 FR 66964), monitoring equipment was installed in association with twelve facilities emitting more than one ton of lead per year (Horsehead Monaca and Bruce Mansfield power plant in Beaver County; East Penn and Exide in Berks County ; Exelon Eddy stone power plant in Delaware County; U.S. Army at Letterkenny in Franklin County; Keystone power plant in Indiana County; Inmetco in Lawren ce County ; Schott in Lu zerne County ; Conemaugh power plant in Westmoreland County; and Bridgeville Glass and Allegheny

Ludlum in Allegheny

County). These monitoring stations were installed and operational by January 1, 2010. In accordance with the Revision s to the Lead Ambient Air Monitoring Requirements, promulgated December 27, 2010 (75 FR 81126), seven facilities were identified as emitting more than 0.5 tons per year in Pennsylvania. Monitoring equipment has been installed at two locations (Mt. Joy Wir e in Lancaster County and Horsehead Palmerton in Carbon County).4

These lead monitoring stations were installed and operational by May 24, 2012. EPA has issued waivers for the remaining facilities. Those facilities are: EME Homer City in Indiana County, All egheny Energy Hatfield in Fayette County, Allegheny Ludlum in Westmoreland County and PPL Montour in Montour County. Waivers were issued for these facilities either because there were no modeled impacts from these facilities or the area of modeled impacts fell in non

- populated areas. Based upon EPA’s review of the submittal, EPA is proposing to determine that the Commonwealth has met its obligations pursuant to 110(a)(2)(B).

**3. Section 110(a)(2)(C)** According to the above referenced submittal, s ections 4 and 8 of the APCA, 35 P.S. §§ 4004 and 4008, provide adequate authority for PA DEP to enforce appropriate limitations and other control measures. Section 6.1(k) of the APCA, 35 P.S. § 4006.1(k), provides that PA DEP shall require revisions to any permit to incorporate applicable standards and regulations promulgated under the CAA after issuance of a Title V permit. Also according to the submittal, Section 9.1 of the APCA, 35 P.S. § 4009.1, provides that PA DEP may

assess civil penalties for violat ions of the APCA, regulations adopted under the APCA, Department orders or terms, and conditions of plan approvals and operating permits. Additionally , Section 7.1 of the APCA, 35 P.S. § 4007.1, authorizes PA DEP to withhold plan approvals, state operating permits, or Title V permits where an applicant or related part y has shown a lack of ability

or intention to comply

with the APCA.
SI P revisions approved by EPA in 40 CFR 52.2020 such as maintenance plans often include enforceable emissions limits, co ntrol measures, fees , and compliance schedules by describing regulations upon which the plans rel y. According to the submittal, the Commonwealth’s enforceable emission limitations and other control measures are covered in those provisions of the APCA and Penns ylvania Code, Title 25, Environmental Protection, Article III, Chapters 121

- 145 (25 Pa. Code Chs. 121

- 145); Title 67, Chapters 175

– 177 that are listed in 40 CFR §52.2020(c)(1); ACHD Regulations, Parts A through I to Articles XX and XXI that are lis ted in 40 CFR 52.2020(c)(2); Philadelphia Title 3 Air Management Code and Philadelphia AMS Regulations I, II, III, IV, V, VII, VIII, XI, and XIII that are listed in 40 CFR 52.2020(c)(3); and source specific provisions codified at 40 CFR 52.2020(d)(1).
A ccording to the submittal, elements of the program for enforcement are found in the monitoring, recordkeeping and reporting requirements for sources in these control measures as well as those provisions of: 25 Pa. Code Chapter 127, subchapters D and E that are listed in 40 CFR 52.2020(c)(1); those provisions of ACHD Regulations, Parts H and I to Articles XX and XXI that are listed in 40 CFR 52.2020(c)(2); and those provisions of the Philadelphia Title 3 Air Management C ode and Philadelphia AMS Regulation Ithat are listed in 40 CFR 52.2020(c)(3).
All areas of the Commonwealth have a SI P approved permitting program in 40 CFR 52.2020

. EPA recentl y approved the Part C permitting program for Alleghen y county into the SI P on5

February 28, 2013 (78 FR 13493). The Commonwealth also has an adequate minor source permitting program for stationary sources to insure the NAAQ S is maintained. Based upon EPA’s review of the submittal, EPA is proposing to determine that the Commonwealth has met its obligations pursuant to 110(a)(2)(C)

. **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 Commonwealth of Pennsylvania as a required SI P submission. See EME Homer City G eneration, L.P. v. EPA, 696 F .3d 7 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 Pennsylvania because section 110(k)(2) of the CAA requires the EPA to act on all SI P submissions. Unless the EME Homer Ci ty 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 quantified 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 proposing to act on all portions of the Commonwealth of Pennsylvania’s 110(a)(2)(D) submission. Based on Pennsylvania’s permitting and emission inventory system, there are no s ources of lead emissions equal to or greater than 0.5 ton per year within a close proximity (less than a 2 mile radius) of the state borders and this submittal includes as supplemental material a map showing lead sources in the Commonwealth for reference. The phy sical properties of lead prevent lead emissions from traveling long distances, and there is a sharp decrease in lead concentrations as the distance from a source increases . Therefore, lead sources in Pennsylvania do not have emissions that impact n eighboring states such that they contribute significantly to nonattainment or interfere with maintenance by any other states. Based upon EPA’s review of the submittal and based upon the Lead Infrastructure Guidance, EPA is proposing to determine that the Commonwea lth has met its obligations pursuant to 110(a)(2)(D)(i)(I).

**Section 110(a)(2)(D)(i)(II)**
For al l areas of Penns yl vania, a SIP approved P revention of Significant Deterioration (PSD) program is in place. The permitting program is codified at 40 CFR 52.2020. See additional discussion under 110(a)(2)(C) . Based upon EPA’s review of the submittal, EPA is proposing to determine that the Commonwealth has met its obligations pursuant to 110(a)(2)(D)(i)(II) for the p art C permit 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

. EPA’s guidance of October 14, 2011, entitled, “Guidance on Infrastructure State Implementation Plan (SIP) Elements Required Under sections6

110(a)(1) and 110(a)(2) for the 2008 Lead (Pb) National Ambient Air Quality Standards (NAAQS)” states that “With regard to the requirem ent of prong 4, i.e. , visibility under subsection (2)(D)(i)(II) significant impacts from Pb emissions from stationary sources are expected to be limited to short distances from the source and most, if not all Pb stationary sources are located at distances from Class I areas such that visibility impacts would be negligible.” This is the case in Pennsy lvania. As described in the Penns yl vania submittal, Pennsylvania does not have a Class I area and the closest Class I areas to Pennsylvania are Brigantine Wil derness in New Jersey and Otter Creek Wilderness in West Virginia which are approximately

70 and 73 kilometers, respectively , from the borders with Pennsy lvania. Pennsyl vani a ’s submittal also included a map showing lead sources and their locations. As d iscussed above, in the section on D(i)(I), based on Pennsylvania’s permitting and emission inventory s ys tem, there are no sources of lead emissions equal to or greater than 0.5 ton per y ear within a close proximity

(less than a 2 mile radius) of the state borders. The phy sical properties of lead prevent lead emissions from traveling long distances, and there is a sharp decrease in lead concentrations as the distance from a source increases. Therefore, lead sources in Penns yl vania do not have emissions that impact neighboring states and as such do not impact visibility protection by

any other states. Based upon EPA’s review of the submittal and based upon the Lead Infrastructure Guidance , EPA is proposing to determine that the Commonwealth has met its obligations pursuant to 110(a)(2)( D ) (i)(II) for visibility protection. In addition, the EPA notes that the approved Pennsylvania SIP still includes the Clean Air Interstate Rule (CAIR) for electrical generating units (EGUs). 2 In2008, the D.C. Circuit remanded CAI R back to EPA. See North Carolina v. EPA , 550 F.3d 1176 (D

. C

. Cir. 2008). The court found CAIR to be inconsistent with the requirements of the CAA, see North Carolina v. EPA , 531 F.3d 896 (D.C. Cir. 2008), but ultimately remanded the rule to EPA without vacatur because it found that “allowing CAIR to remain in effect until it is replaced by a rule consistent with [the court ’ s] opinion would at least temporarily preserve the environmental values covered by CAIR.” North Carolin a , 550 F.3d at 1178. After the remand of CAIR by the D.C. Circuit and the promulgation b y EPA of a new rule

– the Cross State Air Pollution Rule (CSAPR)

– to replace CAIR , the D.C. Circuit issued a decision to vacate CSAPR

. EME Homer City Generation , LP v. EPA , 696 F.3d 7 (D.C. Cir. 2012) , reh’g denied 2013 U.S. App. LEXI S 1623 (Jan. 24, 2013)

. In this decision, the c ourt ordered EPA to “continue administering CAI R pending the promulgation of a valid replacement.” Thus, EPA has been order ed by

the court to develop a new rule, and to continue implementing CAIR in the meantime. EPA is proposing to approve the infrastructure SIP submission with respect to prong 4 in Section 110(a)(2)(D)(i)(II) because Penns yl vania ’s SI P provisions adequately prevent sources in

2 On May 12, 2005, EPA published CAIR, which requires significant reductions in emissions of sulfur dioxide ( SO 2 ) and nitrogen oxides (NOx ) from EGUs to limit the interstate transport of these pollutants and the ozone and fine particulate matter they form in the atmosphere. 70 FR 25162.7

. **Section 110(a)(2)(D)(ii)**
T he Commonwealth has no current or pending obligations pursuant to CAA section s 126 and 115 for the 2008 Lead NAAQS

. EPA is proposing to determine that the Commonwealth has met its obligations pursuant to 110(a)(2)(D)(ii).
**5 . Section 110(a)(2)(E)**  According to the above referenced submittal, the Commonwealth’s enforceable emission limitations and other control measures are covered in : a) the APCA and those provisions of Pennsylvania Code Title 25, Environmental Protection, Article III, Chapters 121

- 145 (25 Pa. Code Chs. 121

- 145) and Title 67, Chapters 175

- 177 that are listed in 40 CFR § 52.2020(c)(1); b) those provisions of ACHD Regulations, Parts A through I to Articles XX and XXI that are listed in 40 CFR §52.2020(c)(2); c) those provisions of Philadelphia Title 3 Air Management Code and Philadelphia AMS Regulations I , II, III, IV, V, VII, VIII, XI, and XIII that are listed in 40 CFR 52.2020(c)(3); and , d) source specific provisions codified at 40 CFR 52.2020(d)(1). The regulations in the Pennsylvania Code are duly adopted by

the Environmental Quality Board. Those adopted b y the local air agencies, namel y ACH D and Philadelphia AMS, are duly adopted by the county

Board of Health, enacted by the County

Council and approved by the Chief Executive and the Air Pollution Control Board, respectively , pursuant to section 12 of the APCA (35 P.S. § 4012). Where these p rovisions relate to section 110 requirements, SI P revisions have been submitted to and approved b y EPA. EPA

- approved SI P revisions are codified at 40 CFR part 52, subpart NN. According to the submittal, Section 12 of APCA (35 P.S. § 4012) establishes the ability of the two pre

- existing local air agencies to continue to operate their own programs. Authority for AMS is provided by

Title 3, Air Management Code and for ACHD b y Article XXI and Count y Ordinance 16782.
Also , the above reference d submittal indicate s Section 6.3 of APCA (35 P.S. § 4006.3) authorizes PA DEP to establish fees sufficient to cover the indirect and direct costs of administering the plan approval and operating permit program including Title V and costs of administering ce rtain committees. 25 Pa. Code §127.701 , as currently approved in the SI P , establishes fees to cover the direct and indirect costs of administering the air pollution control planning process, operating permit program, certain committee operation and to sup port the air pollution control program authorized by state statute. The APCA also authorizes the establishment of fees to cover non

- Title V costs. The air qualit y program also receives revenue from fines and penalties (Clean Air Fund) and federal funds under Sec tions 105 and 103 of the CAA, special federal funds for PM 2.5 , and state general appropriations. PADEP also indicated that it has adequate personnel along with funding and authority to carry out the SI P

. The local8

agencies receive Sectio ns 105 an d 103 funds directly from EPA, have their own authority to collect Title V and other fees, and also receive revenue from fines and penalties that are restricted for air quality

program purposes. PA DEP’s agreements with ACHD and AMS assure that these local agencies similarly have the personnel, funding and authority to carry out their respective obligations under the SI P.
The above referenced submittal indicate s that Section 12 of the APCA reserved powers to political subdivisions to enact air pollution co ntrol ordinances, which are not less stringent than the requirements of the C AA , APCA, and regulations adopted under the acts. The APCA authorizes only

two local air pollution control programs in the Commonwealth, which are administered b y the Philadelphi a AMS and the ACHD. PADEP maintains agreements with the two local air agencies that PADEP relies on for implementation of the SI P in Allegheny and Philadelphia counties. PADEP has approved the local programs in the areas of financial assistance, annual workload projection, emissions reporting, source monitoring and reporting, enforcement, ambient air monitoring and reporting, and air qualit y permitting. PA D EP has responsibilit y for ensuring adequate implementation of SI P provisions by local authorities under S ection 12 of the APCA, 35 P.S. § 4012. The submission of a description of the implementation of the local air pollution control program along with a detailed accounting of the costs of implementation is required on an annual basis. Based upon EPA’s review of the above referenced submittal, and the L ead Infrastructure Guidance, EPA is proposing to determine that the Commonwealth has met its obligations pursuant to 110(a)(2) (E) (i) and 110(a)(2)(E)(iii). EPA will act on 110(a)(2)( E ) (ii) in a separate action.
**6 . Section 110(a)(2)(F)**  According to the above referenced submittal, regulatory requirements related to sampling and testing have been codified in 25 Pa. Code Chapter 139 and requirements in 25 Pa. Code Section §135.3 provide for the reporting of emissions inventories in a format established by PADEP on a schedule set forth in the section. In addition, 25 Pa. Code § 135.21 requires the submission of emission s tatements as required by the CAA. Area, mobile, and non

- road data are reported on a 3

- ye ar cy cle consistent with 40 CFR Part 51.
Also the Commonwealth’s enforceable emission limitations and other control measures are covered in the APCA and those provi sions of Pennsy lvania Code Title 25, Environmental Protection, Article III, Chapters 121

- 145 (25 Pa. Code Chs. 121

- 145), listed in 40 CFR §52.2020(c)(1), ACHD Regulations, Parts A through I to Articles XX and XXI listed in 40 CFR 52.2020(c)(2), Philadelp hia Title 3 Air Management Code , Philadelphia AMS Regulations I, II, III, IV, V, VII, VIII, XI, and XIII listed in 40 CFR 52.2020(c)(3), and, source specific provisions codified at 40 CFR 52.2020(d)(1) and (2). Elements of the program for enforcement are found in the monitoring, recordkeeping and reporting requirements for sources in these control measures as well as 25 PA Code §127, subchapters D and E, ACHD Regulations, Parts H and I to Articles XX and XXI and Philadelphia AMS Regulation I.9

Also accordi ng to the above referenced submittal, the Commonwealth has the responsibility of making all records, reports or information obtained by PADEP or referred to at public hearings under the provisions of the APCA available to the public, except to the extent the records, reports or information are protected by confidentiality

pursuant to APCA section 13.2, 35 P.S. § 4013.2. The ty pes of records PADEP routinely provides access to include notifications, inspection reports, notices of violation, enforcement order s, applications, permit review letters, sample results, monitoring reports, permits, approvals and denials that would relate to §110(a)(2)(F). PADEP generall y makes information available for public access through its website, but also makes hard cop y repo rts available upon written request. Based upon EPA’s review of the submittal and upon the Lead Infrastructure Guidance, EPA is proposing to determine that the Commonwealth has met its obligations pursuant to 110(a)(2)(F).
**7 . Section 110(a)(2)(G)** 
Acco rding to the submittal referenced above, the Commonwealth can request the owners and operators of lead

- emitting facilities to create Standby Plans in accordance with the provision in 25 Pa. Code Chapter 137 (relating to air pollution episodes). Standb y plans, when necessary , must be developed in accordance with the criteria in 25 Pa. Code § 137.4 (relating to standb y plans). While no specific emergency episode plans are required at this time, Pennsy lvania has adequate general emergency powers to address lead related episodes, as appropriate and necessary
. Enabling authority for “Emergency Powers” is contained in Sections 5(5) and 6.2 of the APCA (35 P.S. §§ 4005(5) and 4006.2). ACHD has adopted Part F to Article XX/XXI and Philadelphia AMS has adopted Regulation IV, all of which cover air pollution episodes and the occurrence of an emerge ncy due to the effects of pollutants on the health of persons. The state and local requirements in 25 Pa. Code Chapter 137, Part F to Article XX/XXI and Philadelphia AMS Regulation IV were approved b y EPA and codified in Pennsylvania’s SI P on May 31, 1972 (37 FR 10842), June 16, 1993 (58 FR 33203), June 12, 1998 (63 FR 32126), June 11, 2002 (67 FR 39854), and November 14, 2002 (67 FR 68935). Based upon EPA’s review of the above referenced submittals, EPA is proposing to determine that the Commonwealth has met its obligations pursuant to 110(a)(2)(G).
**8 . Section 110(a)(2)(H)**  According to the above referenced submittal, Section 4(1) of the APCA, 35 P.S. § 4004(1), empowers the Department to implement the provisions of the CAA. Section 5 of the APCA, 3 5 P.S. § 4005, authorizes the Environmental Quality Board to adopt rules and regulations for the prevention, control, reduction and abatement of air pollution. In addition, 25 Pa. Code §131.2 adopts and incorporates the federal NAAQS by reference. The revi sed standards are effective in Pennsylvania on the same effective date set forth in the Federal Register for each new or revised NAAQS. The Department has revised and will continue to revise the SI P as may be necessary when EPA revises the primary or seco ndary

NAAQS and when, if ever, EPA finds the SI P is substantially

inadequate to attain the NAAQS which it implements or otherwise to comply with10

the CAA. The Department has revised and will continue to revise the SI P to take advantage of improved or more e xpeditious methods to attain the NAAQS. Based upon EPA’s review of the above referenced submittal and the L ead Infrastructure Guidance , EPA is proposing to determine that the Commonwealth has met its obligations pursuant to 110(a)(2)(H).
**9 . Section 110(a)(2)(J)**  According to the above referenced submittal, the APCA provides adequate authority for the process for the review of proposed SIP revisions, as required under CAA Sections 121 and 127 and notification of NAAQS violations as required in CAA Section 127. It also provides authority for the public education efforts described in CAA Section 127. Sect ion 4 of the APCA, 35 P.S. § 4004, provides general enabling authority for interaction with the public and local government. Also according to the above referenced submittals, PADEP makes real

- time and historical air quality information available on its Web site. Le ad data is available on the P A DEP web site at http://www.ahs2.dep.state.pa.us/aq_apps/aadata/
PADEP has incorporated by reference into Chapter 127, Subchapter D, the requirements in 40 CFR 52 under section 161 of the CAA (42 U.S.C.A. § 7471) for prevention of significant deterioration in their entirety . These provisions were approved by EPA as part of the SIP and can be found in 40 CFR 52.2020. Philadelphia’s PSD regulations and Alleghen y Count y’s PSD regulations are also in the SI P

. As stated in the Lead Infrastructure Guidance, EPA did not expec t the visibility protection and region al h a ze program requirements f rom Part C of Title Iof the CAA to change with the 2008 Lead NAAQS and therefore EPA con cluded that there are no new applicable visibility pro t ection ob ligations under 110 ( a)(2)(J) from the 2008 Lead NAAQS. EPA discu ss ed for Section 110(a)( 2)(D)(i)(II) how the Comm onw eal th provided r equired visibility protection in accordance with the L ead Infrastructure Guidance. Based upon EPA’s review of the above referenced submittal and upon the Lead Infrastructure Guidance, EPA is proposing to dete rmine that the Commonwealth has met its obligations pursuant to CAA Section 110(a)(2)(J)

.

**1 0**  **.
