Mr. Shawn Garvin 

Regional Administrator 

U.S. Environmental Protection Agency, Region III 

1650 Arch Street (Mail Code: 3RAOO) 

Philadelphia, PA 19103-2029 

Dear Mr. Garvin: 

Enclosed for your approval is a revision to the Pennsylvania State Implementation Plan (SIP) to 

address the requirements of Clean Air Act (CAA) Sections 110(a)(I) and 110(a)(2), which require 

each state to develop and submit to the U.S. Environmental Protection Agency (EPA) a plan that 

provides for the implementation, maintenance, and enforcement of the National Ambient Air 

Quality Standards (NAAQS), within three years after promulgation of a new or revised primary or 

secondary NAAQS, commonly referred to as an 'infrastructure SIP.' The enclosed infrastructure 

SIP revision addresses the requirements under CAA Sections 110(a)(2)(A), 110(a)(2)(B), 

11 O( a)(2)(C), 11 O( a)(2)(D)(i)(II), 11 O( a)(2)(D)(ii), 11 O( a)(2)(E)(i), 11 O( a)(2)(E)(ii), 

110(a)(2)(E)(iii), 110(a)(2)(F)(i), 110(a)(2)(F)(ii), 110(a)(2)(F)(iii), 110(a)(2)(G), 110(a)(2)(H), 

110(a)(2)(J), 110(a)(2)(K), 110(a)(2)(L), and 110(a)(2)(M) for the 2010 I-Hour Sulfur 

Dioxide (S02) NAAQS. The Pennsylvania Department of Environmental Protection (DEP) does 

not address CAA Section 11 O( a )(2 ) (I) in these SIP revisions, per the September 20 13 EPA 

guidance relating to infrastructure SIP revisions. Additionally, DEP is not addressing CAA 

Section 110(a)(2)(D)(i)(I), relating to interstate transport, in this SIP revision. 

The Commonwealth of Pennsylvania has completed its public participation process for this SIP 

revision. DEP opened a public comment period from May 3,2014, to June 6, 2014, and scheduled 

three public hearings to occur on June 4, 2014, if requested by the public. No member of the 

public requested a public hearing or requested to present testimony; DEP, therefore, cancelled the 

three hearings, with notice posted on its website. DEP received comments on the proposed SIP 

revision; a Comment and Response document was developed and is included with this submission. 

The following document is enclosed for your approval: 

1. Infrastructure State Implementation Plan Revision Clean Air Act Sections 110(a)(I) and 

110(a)(2) Applicable Requirements for the 2010 I-HourS02 National Ambient Air Quality

Infrastructure State Implementation Plan Revision Clean Air Act Sections 110(a)(1) and 110(a)(2) 

Applicable Requirements for the 2010 1-hour Sulfur Dioxide National Ambient Air Quality Standard

Background

On June 2, 2010, the U.S. Environmental Protection Agency (EPA) promulgated a new 1-hour sulfur dioxide (SO2) national ambient air 

quality standard (NAAQS). EPA established a 1-hour SO2 standard at a level of 75 parts per billion (ppb), based on the 3-year average of the 

annual 99th percentile of 1-hour daily maximum concentrations. The EPA also revoked both the existing 24-hour and annual primary SO2

standards. (75 FR 35520; June 22, 2010). Section 110 of the Federal Clean Air Act (CAA), 42 U.S.C.A. § 7410, requires states to develop 

State Implementation Plan (SIP) revisions and programs to meet the NAAQS established by EPA to protect public health and welfare. 

Section 110 of the CAA also prescribes general elements for the implementation of SIPs. Sections 110(a)(1) and 110(a)(2) of the CAA 

(42 U.S.C.A. §§ 7410(a)(1) and (2)), require states to submit SIP revisions to the EPA Administrator that provide for implementation, 

maintenance, and enforcement of the NAAQS. This SIP revision, generally referred to as the “infrastructure SIP,” describes basic elements 

designed to assure attainment and maintenance of the 2010 SO2 NAAQS including: ambient air quality monitoring, emission inventories, 

enforcement of control measures, modeling, monitoring, nonattainment new source review, prevention of significant deterioration and 

stationary source monitoring. States are required to submit these infrastructure SIP revisions to EPA within three years from the date a new 

or revised NAAQS is signed by the EPA Administrator.

Sections 110(a)(1) and 110(a)(2) of the CAA (42 U.S.C. §§ 110(a)(1) and 110(a)(2)) describe how states are to implement, maintain and 

enforce a NAAQS. This infrastructure SIP revision fulfills the requirements of Sections 110(a)(1) and 110(a)(2) set forth herein for the 2010 

SO2 NAAQS. Once approved by EPA, the SIP revision will provide a federally enforceable plan of how the Commonwealth of Pennsylvania 

(Commonwealth) will comply with the applicable requirements of Sections 110(a)(1) and 110(a)(2) of the CAA set forth herein for the 2010 

SO2 NAAQS.

Statutory authority for the Pennsylvania air quality program, relating to the responsibilities in the CAA, is codified in the Pennsylvania Air 

Pollution Control Act, 35 P.S. §§ 4001 – 4015 (APCA), including in Section 4 of the APCA, which gives the Pennsylvania Department of 

Environmental Protection (DEP) the power and duty to implement the provisions of the CAA in the Commonwealth. 35 P.S. § 4004(1).

Pursuant to Sections 110(a)(1) and 110(a)(2) of the CAA, the Commonwealth has reviewed applicable provisions in the Pennsylvania APCA, 

the implementing regulations in the Pennsylvania Code, local ordinances and regulations in Philadelphia and Allegheny Counties, and the 

State Implementation Plan found at 40 CFR Part 52 Subpart NN. 
July 2014

Based on the applicable statutory and regulatory authority, Pennsylvania’s SIP provides for the implementation, maintenance, and 

enforcement of the applicable elements set forth in Sections 110(a)(1) and110(a)(2) of the CAA, pertinent to the implementation of the 2010 

SO2 NAAQS.

Requirements for a public comment process are set forth in Section 110(a)(2) of the CAA and 40 CFR § 51.102(d). A public comment period 

was provided from May 3, 2014, to June 6, 2014, with an opportunity for a public hearing.

Clean Air Act 

Section

SIP Requirement Applicable Pennsylvania Statutes and Regulations

§ 110(a)(2)(A) Each implementation 

plan submitted by a 

State under this Act 

shall be adopted by 

the State after 

reasonable notice and 

public hearing. Each 

plan shall include 

enforceable emission 

limitations and other 

control measures, 

means, or techniques 

(including economic 

incentives such as 

fees, marketable 

permits, and auctions 

of emissions rights), as 

well as schedules and 

timetables for 

compliance as may be

necessary or 

appropriate to meet 

the applicable 

requirements of this 

chapter.

The Commonwealth’s enforceable emission limitations and other control measures are

authorized under the APCA, (35 P.S. §§ 4001-4015), and implementing regulations in Title 

25 of the Pennsylvania Code (Pa. Code), Article III, (relating to air resources), Chapters 

121-145 (25 Pa. Code Chapters 121-145); 67 Pa. Code Chapters 175-177 (codified in 40 

CFR § 52.2020(c)(1)); Allegheny County Health Department (ACHD) Regulations, Parts A 

through I to Articles XX and XXI (codified in 40 CFR § 52.2020(c)(2)); Philadelphia Title 

3 Air Management Code and Philadelphia Air Management Services (Philadelphia AMS)

Regulations I, II, III, IV, V, VII, VIII, XI, and XIII (codified in 40 CFR § 52.2020(c)(3));

and source specific provisions codified in 40 CFR § 52.2020(d)(1) and (2). Philadelphia 

and Allegheny Counties both administer local air pollution control programs approved by 

DEP. 

The Article III regulations in the Pennsylvania Code are duly adopted by the Pennsylvania 

Environmental Quality Board (EQB) and implemented and enforced by DEP. Where these 

provisions relate to requirements of Section 110 of the CAA, SIP revisions have been 

submitted to and approved by EPA. EPA-approved SIP revisions for Pennsylvania are 

codified in 40 CFR Part 52, Subpart NN. The Commonwealth has an EPA-approved air 

quality permitting program for plan approval (pre-construction and construction permits) 

and operating permits (for both major and minor facilities), which ensures that all applicable 

requirements are included in the federally enforceable plan approvals and operating permits.

DEP also implements and enforces a federally enforceable general plan approval and 

general operating permit program. 

The regulatory provisions are approved by EPA and codified in 40 CFR §§ 52.2020(c)(1), 

52.2020(c)(2), 52.2020(c)(3), 52.2020(d), 52.2061, 52.2062, 52.2063 and 40 CFR Part 70,

Clean Air Act 

Section

SIP Requirement Applicable Pennsylvania Statutes and Regulations

§ 110(a)(2)(B) Each implementation 

plan submitted by a 

State under this Act 

shall be adopted by 

the State after 

reasonable notice and 

public hearing. Each 

plan shall provide for 

establishment and 

operation of 

appropriate devices, 

methods, systems, and 

procedures necessary 

to

(i) monitor, compile, 

and analyze data 

on ambient air 

quality, and

(ii) upon request, 

make such data 

available to the 

Administrator; 

The Commonwealth’s ambient air quality monitoring data system is authorized under

Section 4(17) of the APCA, 35 P.S. § 4004(17). DEP is authorized under Section 4(17) to 

“determine by means of field studies and sampling the degree of air pollution existing in 

any part of the Commonwealth.” DEP establishes, operates, and maintains a network of 

ambient air monitors throughout Pennsylvania, excluding Philadelphia and Allegheny 

Counties. Philadelphia AMS operates its monitoring network as a Pennsylvania approved 

program under Section 12 of APCA, 35 P.S. § 4012, and the terms of the “Agreement for 

Implementation of the Philadelphia County Air Pollution Control Program,” dated October

2010. The ACHD operates its monitoring network as a Pennsylvania approved program 

under Section 12 of the APCA and the terms of the “Agreement for Implementation of the 

Allegheny County Air Pollution Control Program,” dated October 30, 1998. These 

agreements address data collection, data access and reporting in Philadelphia and Allegheny 

Counties. A copy of the APCA and a copy of the agreements with ACHD and Philadelphia 

AMS are provided in Appendix A. 

The SO2 monitors in the Pennsylvania ambient monitoring network (DEP and local 

agencies) have been designated by EPA as either Reference or Equivalent monitors under

40 CFR Part 53. All ambient air monitors are subjected to the Quality Assurance 

requirements of 40 CFR Part 58, Appendix A. In addition, all samplers are located at sites 

that have met the minimum siting requirements of 40 CFR Part 58, Appendix E.

An annual network design plan is required by 40 CFR § 58.10 to be submitted to the EPA 

Regional Administrator by July 1 of each year. 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 submits an 

annual network design plan to the EPA, for 65 counties in Pennsylvania. ACHD, in 

Allegheny County, and Philadelphia AMS, in Philadelphia County, submit annual network 

design plans for their respective counties. DEP provides a 30-day public comment period 

for the annual network design plan submitted by DEP. ACHD and Philadelphia AMS both 

make the annual network design plans available for public inspection, as required under 40

CFR § 58.10(a)(1), and provide a 30-day comment period. If ACHD or Philadelphia AMS 

are unable to provide the 30-day public comment period for the network design plans, a 

comment period would be provided by the EPA pursuant to 40 CFR § 58.10(a)(2). In 

addition, as required under 40 CFR § 58.14, DEP and the local air agencies provide EPA 

Region III with prior notification of any changes to the network between formal network 

design submissions. As needed, details of these changes are communicated to and approved 

by EPA. Copies of the most recent EPA letters approving the monitoring networks for 

DEP, ACHD and Philadelphia AMS are provided in Appendix A. 

In accordance with 40 CFR Part 58, DEP and the local air pollution control agencies in 

Philadelphia and Allegheny Counties collect and report to EPA all ambient air quality data 

for sulfur dioxide, carbon monoxide, ozone, nitrogen dioxide, course particulate matter, and 

fine particulate matter. 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 Air Quality System (AQS) for updating, pursuant to prescribed AQS procedures (40 

CFR § 58.16). The EPA AQS receives each report within 90 days after the end of the 

quarterly reporting period. 

DEP analyzes such air quality data (including data from the local agencies) to verify

attainment status or progress.

§ 110(a)(2)(C) Each implementation 

plan submitted by a 

State under this Act 

shall be adopted by 

the State after 

reasonable notice and 

public hearing. Each 

plan shall include a 

program to provide 

for the enforcement of 

Sections 4 and 8 of the APCA, 35 P.S. §§ 4004 and 4008, provide adequate authority for 

DEP to enforce appropriate emission limitations and other control measures for all NAAQS. 

Section 6.1(k) of the APCA, 35 P.S. § 4006.1(k), provides that DEP shall require revisions 

to any permit to incorporate applicable standards and regulations promulgated under the 

CAA after issuance of a Title V permit.

The Commonwealth has an EPA-approved air permitting program for the preconstruction, 

construction and operation of both major and minor facilities, which ensures that all 

applicable requirements are included in federally enforceable plan approvals, operating 

permits and general plan approvals and general operating permits. These regulatory

52.2020(c)(3), 52.2020(d), 52.2061, 52.2062, 52.2063 and 40 CFR Part 70, Appendix A.

DEP adopted the requirements promulgated by the EPA under the CAA for a Prevention of 

Significant Deterioration (PSD) of Air Quality Program. These requirements were adopted 

to make the PSD requirements independently enforceable by DEP and to implement Title I, 

Part C of the CAA. The PSD Program is also part of the SIP and is codified in 40 CFR §

52.2020(c)(1). EPA approved a SIP revision pertaining to the PSD Program in Allegheny 

County, as submitted by ACHD, on February 28, 2013 (78 FR 13493). EPA stated in the 

Federal Register notice that the SIP revision for PSD in Allegheny County meets the 

statutory obligations with respect to infrastructure SIP requirements. EPA approved a SIP 

revision pertaining to the PSD Program in Philadelphia County, as submitted by 

Philadelphia AMS, on March 28, 2003 (68 FR 15060). EPA stated in the Federal Register 

notice that the SIP revision including Philadelphia AMS Regulation XIII meets the 

minimum requirements of 40 CFR Part 51 with regard to PSD programs. 

Section 9.1 of the APCA, 35 P.S. § 4009.1, provides that DEP may assess civil penalties for 

violations of the APCA, violations of regulations adopted under the APCA, violations of 

DEP orders or terms, and violations of conditions of plan approvals and operating permits. 

Additionally, Section 7.1 of the APCA, 35 P.S. § 4007.1, authorizes DEP to withhold plan 

approvals, state operating permits, or Title V permits, where an applicant or related party 

has shown a lack of ability or intention to comply with the APCA. 

The Commonwealth’s enforceable emission limitations and other control measures are 

covered in those provisions of the APCA and implementing regulations in 25 Pa. Code 

Chapters 121-145; 67 Pa. Code Chapters 175-177, codified in 40 CFR § 52.2020(c)(1);

Elements of the program for enforcement are found in the monitoring, recordkeeping and 

reporting requirements for sources in these control measures, as well as the following: those 

provisions of 25 Pa. Code Chapter 127, Subchapters D and E codified in 40 CFR §

52.2020(c)(1); those provisions of ACHD Regulations, Parts H and I to Articles XX and

Visibility: Pennsylvania submitted its Regional Haze SIP revision under CAA Section 169 

in December 2010 to address visibility related pollutants. EPA issued a limited disapproval 

and limited approval of Pennsylvania’s Regional Haze SIP revision on June 7, 2012, and 

April 30, 2014, respectively. (77 FR 33642 and 79 FR 24340). The limited disapproval 

resulted from Pennsylvania’s reliance on the Clean Air Interstate Rule (CAIR) to address 

regional emission transport. The limited disapproval included a Regional Haze Federal 

Implementation Plan (FIP) for Pennsylvania, which replaced reliance on CAIR with 

reliance on the Cross-State Air Pollution Rule (CSAPR). The U.S. Court of Appeals 

vacated CSAPR in August 2012 and ordered EPA to continue administering CAIR. EME 

Homer City Generation L.P. v EPA, 696 F.3d 7 (D.C. Cir. 2012), cert. granted 133 S.Ct. 

2857 (2013). The Supreme Court of the United States on April 29, 2014 reversed the Court 

of Appeals’ judgment and remanded the case for further proceedings. Environmental 

Protection Agency v. EME Homer City Generation, L.P., 134 S. Ct. 1584 (2014).

Pennsylvania does not have a Class I area. The closest Class I areas to Pennsylvania are 

Brigantine Wilderness in New Jersey and Otter Creek Wilderness in West Virginia, which 

are approximately 70 and 73 kilometers, respectively, from the borders with Pennsylvania. 

Pennsylvania’s Regional Haze SIP, along with Pennsylvania’s SIP provisions to implement 

CAIR, adequately prevent sources in Pennsylvania from interfering with measures adopted 

by other states to protect visibility.

§ 110(a)(2)(D)(ii) Each implementation 

plan submitted by a 

State under this Act 

shall be adopted by 

the State after 

reasonable notice and 

public hearing. Each 

plan shall contain 

adequate provisions 

insuring compliance 

with the applicable 

requirements of 

sections 115 and

126(b) (relating to 

interstate and 

international pollution 

abatement). 

Major stationary sources for SO2 are currently subject to PSD and nonattainment new 

source review (NNSR) permitting programs, as described in this SIP revision for §

110(a)(2)(C) and (J). DEP implements and enforces the PSD and NNSR in all areas of the 

Commonwealth, except Philadelphia and Allegheny Counties; those counties administer 

and enforce approved local air pollution control programs under Section 12 of the APCA. 

NNSR and PSD provisions are codified in Pennsylvania’s SIP at 40 CFR §§ 52.2020(c)(1), 

52.2020(c)(2), 52.2020(c)(3), 52.2020(d), 52.2058(a) and 52.2061.

Section 110(a)(2)(D)(ii) of the CAA provides that each SIP shall “insure compliance” with 

the applicable requirements of Sections 126 and 115 of the CAA relating to interstate and 

international pollution abatement. 

Pursuant to Section 126 of the CAA, on November 7, 2011, EPA promulgated SO2

emission limitations and reporting requirements for the coal-fired boilers (Units 1 and 2) at 

the Portland Generating Station located in Northampton County, Pennsylvania (Portland 

Facility) after EPA made a finding that the coal-fired units at the Portland Facility 

significantly contribute to nonattainment for the 1-hour SO2 NAAQS in New Jersey. See 76 

FR 69052 (relating to final response to petition from New Jersey regarding SO2 emissions 

from the Portland Generating Station). The federally enforceable SO2 emission limitations 

and reporting requirements for the coal-fired boilers (Units 1 and 2) at the Portland Facility 

are established in 40 CFR § 52.2039.

(continued)

The limits and requirements in 40 CFR § 52.2039, are “applicable requirements” as defined 

in 25 Pa. Code § 121.1 (which is included in the federally enforceable Pennsylvania SIP) 

because they have been promulgated or approved by the EPA under the CAA or the 

regulations adopted under the CAA through rulemaking. As applicable requirements, they 

must therefore be included in a Title V operating permit pursuant to 25 Pa. Code § 127.502.

However a revision will not be required if, among other things, less than three years remain 

in the permit term. 25 Pa. Code § 127.463(c). In the case of the Portland Facility, whose 

Title V permit expired on January 31, 2005, the terms and conditions of that permit are 

automatically continued pending issuance of the new permit. 25 Pa. Code § 127.446(c). 

Regardless of whether a revision is required under Section 127.463, the permittee of the 

Portland Facility is required to meet the applicable standards in 40 CFR § 52.2039, within 

the timeframe required by those standards. 25 Pa. Code § 127.463(e). 

Pennsylvania’s Title V permit program (25 Pa. Code §§ 127.501-127.543) is an approved 

Title V permit program.1 DEP has authority to enforce compliance with the terms of any 

Title V operating permit through 25 Pa. Code § 127.513. Each Title V permit must contain 

provisions to, among other things, allow DEP to sample or monitor at reasonable times 

substances or parameters for the purpose of assuring compliance with the permit or 

applicable requirements authorized by the CAA. 25 Pa. Code § 127.513(2)(iv). 

Therefore, DEP contends that the Pennsylvania SIP contains provisions in 

25 Pa. Code §§ 121.1 and 127.463 (in addition to its federally approved Title V operating 

permit program) which insure compliance with the emission limits and reporting 

requirements EPA established for the Portland Facility because the limits and requirements 

are applicable requirements, subject to inclusion in the Portland Facility’s Title V permit, 

and directly enforceable by DEP through the federally approved SIP provision at 

25 Pa. Code 127.463.

 

1 EPA promulgated final approval of the Pennsylvania Title V program on August 29, 1996. See 40 C.F.R. Part 70, Appendix A. See also 61 FR 39597, 

(July 30, 1996). Pennsylvania’s Title V program became effective on November 26, 1994. 24 Pa.B. 5899.

DEP is not intending through this SIP submission to incorporate by reference the Portland 

Facility’s SO2 emission limits in 40 CFR § 52.2039 into the Pennsylvania SIP. DEP

however has duly explained herein how the Pennsylvania SIP and its federally approved

and other control measures are authorized by the following: the APCA and applicable 

implementing provisions in 25 Pa. Code Chapters 121-145; 67 Pa. Code Chapters 175-177 

codified in 40 CFR § 52.2020(c)(1); provisions of ACHD Regulations, Parts A through I to 

Articles XX and XXI codified in 40 CFR § 52.2020(c)(2); provisions of Philadelphia Title 3 

Air Management Code and Philadelphia AMS Regulations I, II, III, IV, V, VII, VIII, XI, 

and XIII codified in 40 CFR § 52.2020(c)(3); and source specific provisions codified in 40 

CFR § 52.2020(d)(1). The regulations in the Pennsylvania Code are adopted by the EQB

and promulgated under the Commonwealth Documents Law. Section 12 of the APCA 

reserves powers to political subdivisions to enact air pollution control ordinances, which are 

not less stringent than the requirements of the CAA, the APCA, and regulations adopted 

under the acts. Section 12 of the APCA authorizes only two local air pollution control 

programs in the Commonwealth, which are administered by Philadelphia AMS and ACHD. 

See ‘Local Agency Legal Authority’ for further information about the Philadelphia AMS 

and ACHD programs.

Local Agency Legal Authority: Section 12 of the APCA (35 P.S. § 4012) authorizes local 

air pollution control programs in any county of the first or second class of the 

Commonwealth; these are Philadelphia and Allegheny Counties. Consistent with Section 

12 of the APCA and the terms of DEP’s approval of the counties’ local air pollution control 

programs, the local agencies continue to operate their own programs, which, at a minimum,

must meet the requirements of the APCA, the CAA and the regulations adopted under the 

acts. The ACHD local air pollution control program is authorized under County Ordinance 

16782 and implementing regulations in Article XXI. Regulations in Allegheny County are 

adopted by the Allegheny County Board of Health, enacted by Allegheny County Council, 

and approved by the Allegheny County Chief Executive. The enabling authority for 

Philadelphia AMS is provided by Title 3, Air Management Code. Ordinances that make up 

the Philadelphia Code in Philadelphia County are passed by the Philadelphia City Council 

and approved by the Mayor of Philadelphia. Title 3 of the Philadelphia Code authorizes the 

City’s Air Pollution Control Board to promulgate Air Management Regulations; Title 3 of 

the Philadelphia Code and the Air Management Regulations are enforced by Philadelphia

AMS. Where these provisions relate to requirements in Section 110 of the CAA, SIP 

revisions have been submitted to and approved by EPA. EPA-approved SIP revisions are 

codified in Pennsylvania’s SIP at 40 CFR Part 52, Subpart NN. 

State Revenue: Section 6.3 of the APCA (35 P.S. § 4006.3) authorizes the EQB to 

establish, by regulation, a permanent annual air emission fee, as required for regulated 

pollutants by Section 502(b) of the CAA (42 U.S.C.A. § 7661a(b)), to cover the reasonable 

direct and indirect costs of administering the operating permit program required by Title V 

of the CAA, other related requirements of the CAA, and the reasonable indirect and direct 

costs of administering the Small Business Stationary Source Technical and Environmental 

Compliance Assistance Programs, including the Small Business Compliance Advisory 

Committee and the Office of Small Business Ombudsman. The emission fee shall not apply 

to emissions of more than 4,000 tons of any regulated pollutant. Section 6.3 of the APCA 

also authorizes the EQB, by regulation, to establish fees to support the air pollution control 

program authorized by the APCA and not covered by fees required by Section 502(b) of the

CAA.

The implementing air quality fee provisions are codified in 25 Pa. Code Chapter 127, 

Subchapter I (relating to plan approval and operating permit fees). The APCA also 

authorizes the establishment of fees to cover non-Title V costs. Pennsylvania’s air quality 

program also receives revenue from fines and civil penalties.

Section 9.2 of the APCA provides that all fines, civil penalties, and fees collected under the 

APCA shall be paid into the Treasury of the Commonwealth in a special fund known as the 

Clean Air Fund (CAF), which shall be administered by DEP for use in the elimination of air 

pollution. Section 9.2 of the APCA further provides that DEP may establish such separate 

accounts, as may be necessary, to implement the requirements of the APCA and the CAA. 

The fees are deposited into restricted accounts in the CAF and are used as prescribed in the 

statutes and implementing regulations. DEP prepares Comparative Financial Statements for 

each account in the CAF, and projects the expenditures out five years to assure the stability

of the fund. CAF Spending Plans are developed and approved for two fiscal years. DEP

receives federal funds under Sections 105 and 103 of the CAA. State General Fund 

appropriations are used to match the Section 105 grant.

Local Revenue: The local agencies have their own authority to collect Title V and other 

fees, receive Section 105 and 103 funds directly from EPA, and also receive revenue from 

fines and penalties, that are restricted for air quality program purposes.

State Staffing: DEP has adequate personnel to implement the SIP with respect to the 2010

SO2 NAAQS requirements. Should EPA determine that DEP lacks adequate personnel to 

implement the SIP, EPA is authorized to issue a finding with respect to that deficiency, 

which DEP would have a legal obligation to correct within 18 months after such finding. 

Local Staffing: DEP’s Agreement for Implementation of the Philadelphia County Air 

Pollution Control Program and the Agreement for Implementation of the Allegheny County 

Air Pollution Control Program (see § 110(a)(2)(B) element, above) assure that the two 

DEP-approved local agencies similarly have the necessary personnel, funding and authority 

to carry out their respective obligations under the SIP.

pollution control programs in the Commonwealth, which are administered by Philadelphia 

AMS and ACHD. DEP maintains agreements with these two local air agencies, upon 

whom DEP relies for implementation of the SIP in Allegheny and Philadelphia Counties. 

DEP 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 quality permitting. DEP has responsibility for ensuring 

adequate implementation of SIP provisions by local authorities under Section 12 of the 

APCA, 35 P.S. § 4012. The submission to DEP 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. Section 12(e) of the APCA authorizes DEP, 

under certain conditions, to refuse approval, or to suspend or rescind approval, of county air 

pollution control agencies’ air pollution control programs, in which case, authority for the 

delegated responsibilities would revert to DEP.

the Commonwealth’s SIP on July 30, 1996. See 40 CFR § 52.2020 (c)(110)(i)(C).

The Pennsylvania SIP, applicable laws and regulations do not contain any provisions that 

prevent the use of any credible evidence (including continuous emissions monitoring data) 

to establish violations of applicable requirements.

The Commonwealth’s enforceable emission limitations and other control measures are 

authorized by and contained in the following: the APCA provisions of 25 Pa. Code

Chapters 121-145 codified in 40 CFR § 52.2020(c)(1); 67 Pa. Code Chapters 175-177

provisions of the APCA, available to the public, except to the extent the records, reports or 

information are determined by DEP to be confidential under Section 13.2 of the APCA, 

35 P.S. § 4013.2. The types of records DEP routinely provides access to include 

notifications, inspection reports, notices of violation, enforcement orders, applications, 

permit review letters, sample results, monitoring reports, permits, approvals and denials that 

would relate to § 110(a)(2)(F) of the CAA. All emissions data to which DEP has access is 

not considered confidential information. DEP makes information available for public 

access through its Web site (www.depweb.state.pa.us), but also makes hard copy reports 

available upon written request. DEP does not submit an annual stationary source inventory 

to EPA based on SO2 emissions. DEP does, however, include reporting requirements for 

SO2 in permits issued to stationary sources in the Commonwealth. Stationary facilities are 

required to submit an Annual Emission Statement (AES); nitrogen oxides (NOX), sulfur 

oxides (SOX), volatile organic compounds (VOC), course particulate matter (PM10), fine 

particulate matter (PM2.5), ammonia (NH3) and carbon monoxide (CO) emissions of 1.0 ton 

per year or more per sub facility must be reported on a sub facility by sub facility basis. 

DEP supplies facilities with reporting instructions in the document “Instructions for 

Completing the Annual Emission Statement Reporting Forms – rev 11/2007” (DEP 

Document #2700-BK-DEP1936). All emissions reported on the AES are entered into 

DEP’s computer system: Air Information Management System / environment, Facility, 

Application, Compliance Tracking System (AIMS/eFACTS). The public can search the 

eFACTS system online at the website http://www.ahs.dep.pa.gov/eFACTSWeb/default.aspx 

to find facility specific reports or reports of all facilities emitting a specific pollutant. The 

public can request copies of permits or other non-confidential information by contacting 

DEP directly. Additionally, AIMS/eFACTS data is provided to the federal National 

Emission Inventory (NEI) database and to other state agencies and the public upon request.

NAAQS, the provisions will automatically be adopted and incorporated in the Pennsylvania 

Code. DEP submitted an ACHD SIP revision for PSD, which was approved by EPA on 

February 28, 2013 (78 FR 13493) and a Philadelphia AMS SIP Revision for PSD, which 

was approved by EPA on March 28, 2003 (68 FR 15060). Both SIP revisions are codified 

in 40 CFR Part 52 Subpart NN.

This SIP revision does not address requirements under the CAA Section 110(a)(2)(J), 

relating to the visibility sub-element. EPA has stated, in guidance issued September 2013, 

that air agencies do not need to address the visibility sub-element of Section 110(a)(2)(J) in 

this infrastructure SIP submission, because there are no new applicable visibility protection

power and duty is the obligation to meet the NAAQS established under the CAA. 

Section 4(15) of the APCA provides that DEP has the power and duty to conduct or cause 

to be conducted studies and research with respect to air contaminants, their nature, causes 

and effects, and with respect to the control, prevention, abatement and reduction of air 

pollution and air contamination. 35 P.S. § 4004(15). This enabling legislation empowers 

DEP to perform air quality modeling and to make data submissions prescribed by the 

Administrator of EPA, in accordance with Section 110(a)(2)(K) of the CAA. Additionally, 

DEP has incorporated by reference, in its entirety, 40 CFR § 52.2058 (relating to prevention 

of significant air quality deterioration) in 25 Pa. Code §§ 127.81-83, which applies 

statewide except for Allegheny and Philadelphia Counties. The adoption of the federal PSD

§ 110(a)(2)(L) Each implementation 

plan submitted by a 

State under this Act 

shall be adopted by 

the State after 

reasonable notice and 

public hearing. Each 

plan shall require the 

owner or operator of 

each major stationary

as a condition of any 

permit required under 

this chapter, a fee 

sufficient to cover—

Permitting Fees: The fee requirements of 25 Pa. Code Chapter 127, Subchapter I, were 

approved by EPA as meeting the CAA requirements and were incorporated into the 

Commonwealth’s SIP. The Commonwealth’s Title V operating permit program,

implemented in accordance with 25 Pa. Code Chapter 127, Subchapters F and G, was 

approved by EPA on July 30, 1996 (61 FR 39597). While permit fees are standardized for 

the entire Commonwealth, collection of fees and Title V permitting activities are shared by 

DEP, ACHD and Philadelphia AMS. ACHD and Philadelphia AMS collect Title V fees 

within their respective jurisdictions, and use the fees to fund the Title V permitting program 

for each agency. DEP collects permit fees and administers the Title V permitting program 

for the rest of the state. DEP is also authorized by 25 Pa. Code § 127.706 to transfer 

additional funds to the local agencies, if needed, to operate the Title V permitting program. 

Permitting fees cover reasonable costs of reviewing and acting upon permit applications and 

reasonable costs of implementing and enforcing permit terms.

State under this Act 

shall be adopted by 

the State after

Section 7 of the APCA (relating to public hearings), 35 P.S. § 4007, requires the EQB, or 

DEP, acting on behalf of the EQB, to conduct public hearings in any region of the 

Commonwealth affected before any rules or regulations with regard to the control, 

abatement, prevention or reduction of air pollution are adopted for that region. Section 7 

also requires notice to the public, published in newspapers of general circulation, of the 

time and place of any public hearing at least thirty days prior to the scheduled date of the 

hearing. Section 7.5 of the APCA (relating to public review of state implementation plans), 

35 P.S. § 4007.5 requires notice of a proposed SIP to be published in the Pennsylvania 

Bulletin and in newspapers of general circulation for the area affected by the proposed SIP. 

Pennsylvania does not have any laws and DEP does not have any regulations, applicable to 

DEP’s Bureau of Air Quality, that specifically require direct consultation and participation 

by local political subdivisions affected by a SIP. Local political subdivisions affected by a 

SIP are provided with the same opportunity as all other members of the public to review
