I. Background 

The formal SIP revision submittal, 

prepared by ACHD, was submitted by 

PADEP on June 17, 2011. The SIP 

revision included the 1997 annual PM2.5

NAAQS attainment plan for the LibertyClairton Area, a 2002 base year 

emissions inventory for purposes of 

meeting the requirement of section 

172(c)(3) of the CAA, the transportation 

conformity motor vehicle emissions 

budgets (MVEBs), and certain revisions 

to ACHD regulations. This SIP revision 

is described in further detail in section 

II of this rulemaking action. 

On November 7, 2011 (76 FR 68699), 

EPA published a notice of proposed 

rulemaking (NPR) for the 

Commonwealth in Pennsylvania. In the 

NPR, EPA proposed conditional 

approval of the 1997 annual PM2.5

NAAQS attainment plan for the LibertyClairton Area (the ‘‘attainment plan’’). 

EPA proposed conditional approval 

because the attainment plan included 

air quality modeling that relied on 

emissions reductions from the Clean Air 

Interstate Rule (CAIR), which was 

problematic because at the time CAIR 

was no longer in place. EPA had 

promulgated the Cross State Air 

Pollution Rule (CSAPR) on August 8, 

2011 (76 FR 48208) to replace CAIR. As 

part of this NPR, EPA also proposed to 

approve the amendments to ACHD 

regulations included in the June 17, 

2011 SIP revision, which added the 

definition of PM2.5 and the level of the 

1997 annual and 2006 24-hour PM2.5

NAAQS. No public comments were 

received on this NPR. 

On October 25, 2013 (78 FR 63881), 

EPA determined that the LibertyClairton Area had attained the 1997 

annual PM2.5 NAAQS, based on qualityassured and certified ambient air quality 

data for the 2009–2011 and 2010–2012 

monitoring periods. This ‘‘clean data 

determination’’ suspended the 

requirement for the Liberty-Clairton 

Area to submit an attainment 

demonstration, reasonably available 

control measures (RACM), reasonable 

further progress (RFP), and contingency 

measures related to attainment of the 

1997 annual PM2.5 NAAQS, for so long 

as the Area continues to attain the 1997 

annual PM2.5 NAAQS. 

On November 18, 2013, PADEP 

submitted a letter requesting to 

mstockstill on DSK4VPTVN1PROD with RULES

Federal Register / Vol. 79, No. 1 / Thursday, January 2, 2014 / Rules and Regulations 55 

1See ‘‘State Implementation Plans; General 

Preamble for the Implementation of Title I of the 

Clean Air Act Amendments of 1990,’’ (57 FR 13498, 

April 16, 1992) (hereafter, General Preamble). EPA 

notes that it has issued additional guidance for 

attainment plans for PM10 in particular, including 

extra requirements for areas classified as ‘‘serious’’ 

nonattainment areas under subpart 4. See ‘‘State 

Implementation Plans for Serious PM10

Nonattainment Areas, and Attainment Date Waivers 

for PM10 Nonattainment Areas Generally; 

Addendum to the General Preamble for the 

Implementation of Title I of the Clean Air Act 

Amendments of 1990,’’ (59 FR 41998, August 

16,1994) (hereafter, Addendum). 

2See 57 FR 13538. 3See General Preamble, 57 FR 13539. EPA notes, 

however, that under subpart 4 requirements states 

may need to submit updated emissions inventories 

to support later SIP submissions, such as SIP 

submissions to address the requirements for serious 

areas under section 189(b)(1), or the requirements 

for an extension of the serious area attainment date 

under section 188(e). 

4See 40 CFR 51.1008. 

5See PM2.5 Implementation Rule, 72 FR 20648. 

EPA noted that the obligation to address all of the 

scientific precursors of PM2.5 was a separate 

requirement needed to support various regulatory 

purposes, including the evaluation of whether 

relying on the rebuttable presumptions for 

precursors was correct in a given area. 

withdraw the sections of the June 17, 

2011 SIP revision pertaining to the 

suspended planning requirements for 

the Liberty-Clairton Area as a result of 

EPA’s determination of attainment for 

the Area. Specifically, PADEP requested 

to withdraw all portions of the June 17, 

2011 SIP revision, except for the 

portions pertaining to the 2002 base 

year emissions inventory and the 

revisions to the ACHD regulations, 

which are discussed in section 2 

(Regulatory Changes), section 6 

(Emissions Inventory), and appendix F 

(Stationary Point, Area, Nonroad, and 

Mobile Emissions Inventories) of the SIP 

submittal. As a result of PADEP’s 

November 18, 2013 letter, EPA has no 

statutory obligation to take further 

action on the portions of the June 17, 

2011 SIP revision that have been 

withdrawn. Therefore, in this 

rulemaking action, EPA is only 

approving of the June 17, 2011 

submittal, the 2002 base year emissions 

inventory and the submitted revisions to 

ACHD regulations. 

II. Summary of State Submittal 

As discussed in this rulemaking 

action, the 2002 base year emissions 

inventory was submitted by PADEP as 

part of the June 17, 2011 SIP revision. 

The base year emissions inventory 

includes emissions estimates that cover 

the general source categories of point 

sources, non-road mobile sources, area 

sources, on-road mobile sources, and 

biogenic sources. The pollutants that 

comprise the inventory are nitrogen 

oxides (NOX), volatile organic 

compounds (VOC), PM2.5, coarse 

particles (PM10), ammonia, and sulfur 

dioxide (SO2). In accordance with 40 

CFR 51.1008(b), PADEP selected 2002 as 

the base year for the emissions 

inventory. EPA has reviewed the results, 

procedures and methodologies for the 

2002 base year emissions inventory 

submitted by PADEP and finds them 

approvable. Further analysis of the 

emissions inventory development can 

be found in the June 17, 2011 SIP 

submittal and in EPA’s October 5, 2011 

technical support document (TSD) 

included as part of the docket for this 

rulemaking action. See Docket ID 

Number EPA–R03–2011–0854. 

The SIP submittal also included the 

following amendments to ACHD 

regulations, which became effective on 

May 24, 2010: (1) The addition of the 

1997 annual PM2.5 standard level of 15 

mg/m3, the 2006 24-hour PM2.5 standard 

level of 35 mg/m3, and the related 

references to the list of standards in 

ACHD article XXI section 2101.10 and 

(2) the addition of the definition of 

‘‘PM2.5’’ to ACHD article XXI section 

2101.20. These regulatory amendments 

are described in sections 2 and 6 and 

appendix F of the June 17, 2011 SIP 

submittal. EPA’s rationale for approving 

the described SIP revisions was 

provided in the NPR and will not be 

restated here. 

III. Effects of Recent Court Decisions 

On January 4, 2013, in Natural 

Resources Defense Council v. EPA, the 

D.C. Circuit remanded to EPA both the 

‘‘Final Clean Air Fine Particle 

Implementation Rule’’ (72 FR 20586, 

April 25, 2007) and the 

‘‘Implementation of the New Source 

Review (NSR) Program for Particulate 

Matter Less than 2.5 Micrometers 

(PM2.5)’’ final rule (73 FR 28321, May 

16, 2008) (collectively, ‘‘1997 PM2.5

Implementation Rule’’ or 

‘‘Implementation Rule’’). See 706 F.3d 

428 (D.C. Cir. 2013). The Court found 

that EPA erred in implementing the 

1997 annual PM2.5 NAAQS pursuant 

solely to the general implementation 

provisions of subpart 1 of part D of Title 

I of the CAA (subpart 1), rather than the 

particulate-matter-specific provisions of 

subpart 4 of part D of Title I of the CAA 

(subpart 4). As a result, the D.C. Circuit 

Court remanded EPA’s Implementation 

Rule and instructed EPA ‘‘to 

repromulgate these rules pursuant to 

subpart 4 consistent with this opinion.’’ 

Significantly, the Court’s decision 

remanded the rules to EPA and did not 

vacate them. In a future rulemaking 

action, EPA intends to respond to the 

Court’s remand and to promulgate new 

implementation regulations for the 

PM2.5 NAAQS in accordance with the 

requirements of subpart 4. In the 

interim, EPA will proceed to review 

attainment plans that have already been 

submitted but are not yet approved 

where appropriate. 

EPA has two longstanding general 

guidance documents that interpret the 

1990 amendments to the CAA, 

commonly known as the ‘‘General 

Preamble’’ and the ‘‘Addendum,’’ that 

make recommendations to states for 

meeting the statutory requirements for 

SIPs for nonattainment areas including 

those of subpart 4.1 In the General 

Preamble, EPA discussed the 

relationship of subpart 1 and subpart 4 

SIP requirements, and pointed out that 

subpart 1 requirements were to an 

extent ‘‘subsumed by, or integrally 

related to, the more specific PM10

requirements.’’ 2 Section 172(c)(3) of the 

CAA requires that States submit a 

comprehensive, accurate, and current 

inventory of actual emissions from all 

sources in the nonattainment area. In 

the General Preamble, EPA stated that 

section 172(c)(3) applies for purposes of 

subpart 4, which itself contains no 

additional emissions inventory 

requirements for purposes of PM10.3

Thus, subpart 4 adds no additional 

emissions inventory requirements. 

EPA’s remanded 1997 PM2.5

Implementation Rule required States to 

meet emissions inventory requirements, 

including a statewide emissions 

inventory of direct PM2.5 and all PM2.5

precursors, any additional emissions 

inventory information needed to 

support an attainment demonstration 

and RFP requirements, and a baseline 

(i.e. base year) emissions inventory 

suitable for the SIP planning 

requirements for the area at issue.4 As 

EPA explained in the 1997 PM2.5

Implementation Rule, in order to ensure 

that States provide the information 

necessary for SIP planning, including 

the need to evaluate which PM2.5

precursors a state should regulate in a 

given nonattainment area, the 

requirements relating to emissions 

inventories include a requirement that 

States must provide emissions 

information for direct PM2.5, SO2, NOX, 

VOCs, and ammonia.5

EPA believes that the D.C. Circuit 

Court’s decision in NRDC v. EPA does 

not affect the emissions inventory 

requirements for the 1997 annual PM2.5

NAAQS. The D.C. Circuit Court’s 

remand of the 1997 PM2.5

Implementation Rule to EPA with 

instructions to repromulgate 

implementation regulations consistent 

with subpart 4 would not result in 

additional emissions inventory 

requirements under subpart 4 because

7For further details, see the TSD document 

entitled ‘‘Technical Support Document (TSD) for 

Liberty-Clairton PM2.5 Nonattainment Area: State 

Implementation Plan (SIP) Attainment 

Demonstration and Base Year Inventory,’’ dated 

October 5, 2011. The TSD is available in the docket 

online at www.regulations.gov, Docket Number 

EPA–R03–OAR–2011–0854. 

none exist. The D.C. Circuit Court’s 

comments on addressing PM2.5

precursors consistent with subpart 4 

requirements also would not compel a 

different approach with respect to 

emissions inventories from that which 

EPA required under subpart 1. EPA’s 

prior approach under subpart 1 already 

obligated States to include emissions of 

direct PM2.5, SO2, NOX, VOCs, and 

ammonia in such inventories, and 

provided no presumptions to exclude 

precursors from inventories. To the 

contrary, the emissions inventory 

requirement includes these precursors 

to assure adequate information to 

inform decisions about what pollutants 

to regulate for purposes of attaining the 

NAAQS in a given area. 

As part of EPA’s November 7, 2011 

NPR, EPA proposed approval of LibertyClairton Area’s submission with respect 

to emissions inventory requirements.6

In that NPR, EPA explained that the 

Liberty-Clairton Area’s emissions 

inventory information was consistent 

with EPA’s guidance and correctly 

included the emissions of direct PM2.5,

SO2, NOx, VOC, and ammonia.7

Additionally, EPA provided a 

discussion of the sources of information 

for emissions from stationary sources, 

area sources, and mobile sources in the 

Liberty-Clairton Area and an 

explanation supporting its proposed 

finding that the State’s approach was 

appropriate. No comments were 

received for this NPR. 

Because the emissions inventories, 

submitted by PADEP as part of LibertyClairton Area’s attainment plan for the 

1997 annual PM2.5 NAAQS, already 

included emissions of direct PM2.5, SO2, 

NOx, VOC, and ammonia, EPA 

concludes that there is no need to 

reexamine the emissions inventories for 

the Liberty-Clairton Area. EPA finds 

that the process used to develop the 

2002 base year emissions inventory for 

the Liberty-Clairton Area is adequate to 

meet the requirements of CAA section 

172(c)(3), the implementing regulations, 

and EPA guidance for emission 

inventories with respect the 1997 

annual PM2.5 NAAQS. 

IV. Final Action 

EPA is approving into the 

Pennsylvania SIP the 2002 base year 

emissions inventory for the LibertyClairton Area for the 1997 annual PM2.5

NAAQS, which was submitted as part of 

the June 17, 2011 submittal. EPA is also 

approving into Pennsylvania’s SIP 

revisions to article XXI, sections 

2101.10 and 2101.20 of ACHD 

regulations for the addition of the 

definition of PM2.5 and the levels of the 

1997 annual PM2.5 and the 2006 24-hour 

PM2.5 standards. EPA is not taking 

action on the remaining portions of the 

June 17, 2011 submittal, as they were 

withdrawn by PADEP by a November 

18, 2013 letter. 

V. Statutory and Executive Order 

Reviews 

A. General Requirements 

Under the CAA, the Administrator is 

required to approve a SIP submission 

that complies with the provisions of the 

CAA and applicable Federal regulations. 

42 U.S.C. 7410(k); 40 CFR 52.02(a). 

Thus, in reviewing SIP submissions, 

EPA’s role is to approve State choices, 

provided that they meet the criteria of 

the CAA. Accordingly, this action 

merely approves state law as meeting 

Federal requirements and does not 

impose additional requirements beyond 

those imposed by State law. For that 

reason, this action: 

• Is not a ‘‘significant regulatory 

action’’ subject to review by the Office 

of Management and Budget under 

Executive Order 12866 (58 FR 51735, 

October 4, 1993); 

• does not impose an information 

collection burden under the provisions 

of the Paperwork Reduction Act (44 

U.S.C. 3501 et seq.); 

• is certified as not having a 

significant economic impact on a 

substantial number of small entities 

under the Regulatory Flexibility Act (5 

U.S.C. 601 et seq.); 

• does not contain any unfunded 

mandate or significantly or uniquely 

affect small governments, as described 

in the Unfunded Mandates Reform Act 

of 1995 (Pub. L. 104–4); 

• does not have Federalism 

implications as specified in Executive 

Order 13132 (64 FR 43255, August 10, 

1999); 

• is not an economically significant 

regulatory action based on health or 

safety risks subject to Executive Order 

13045 (62 FR 19885, April 23, 1997); 

• is not a significant regulatory action 

subject to Executive Order 13211 (66 FR 

28355, May 22, 2001); 

• is not subject to requirements of 

Section 12(d) of the National 

Technology Transfer and Advancement 

Act of 1995 (15 U.S.C. 272 note) because 

application of those requirements would 

be inconsistent with the CAA; and 

• does not provide EPA with the 

discretionary authority to address, as 

appropriate, disproportionate human 

health or environmental effects, using 

practicable and legally permissible 

methods, under Executive Order 12898 

(59 FR 7629, February 16, 1994). 

In addition, this rule does not have 

tribal implications as specified by 

Executive Order 13175 (65 FR 67249, 

November 9, 2000), because the SIP is 

not approved to apply in Indian country 

located in the state, and EPA notes that 

it will not impose substantial direct 

costs on tribal governments or preempt 

tribal law. 

B. Submission to Congress and the 

Comptroller General 

The Congressional Review Act, 5 

U.S.C. 801 et seq., as added by the Small 

Business Regulatory Enforcement 

Fairness Act of 1996, generally provides 

that before a rule may take effect, the 

agency promulgating the rule must 

submit a rule report, which includes a 

copy of the rule, to each House of the 

Congress and to the Comptroller General 

of the United States. EPA will submit a 

report containing this action and other 

required information to the U.S. Senate, 

the U.S. House of Representatives, and 

the Comptroller General of the United 

States prior to publication of the rule in 

the Federal Register. A major rule 

cannot take effect until 60 days after it 

is published in the Federal Register. 

This action is not a ‘‘major rule’’ as 

defined by 5 U.S.C. 804(2). 

C. Petitions for Judicial Review 

Under section 307(b)(1) of the CAA, 

petitions for judicial review of this 

action must be filed in the United States 

Court of Appeals for the appropriate 

circuit by March 3, 2014. Filing a 

petition for reconsideration by the 

Administrator of this final rule does not 

affect the finality of this action for the 

purposes of judicial review nor does it 

extend the time within which a petition 

for judicial review may be filed, and 

shall not postpone the effectiveness of 

such rule or action. This action, which 

approves the 2002 base year emissions 

inventory for the Liberty-Clairton Area 

for the 1997 annual PM2.5 NAAQS and 

revisions to ACHD regulations of the 

PM2.5 definitions and levels, may not be 

challenged later in proceedings to 

enforce its requirements. (See section 

307(b)(2).)
