Determinations of Attainment of the 

1997 Annual Fine Particulate Standard 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed rule. 

SUMMARY: EPA is proposing to make two 

determinations regarding the PittsburghBeaver Valley fine particulate matter 

(PM2.5) nonattainment area (hereafter 

referred to as ‘‘the Pittsburgh Area’’ or 

‘‘the Area’’). First, EPA is proposing to 

determine that the Area has attained the 

1997 annual PM2.5 National Ambient 

Air Quality Standard (NAAQS). This 

proposed determination of attainment is 

based upon complete, quality-assured 

and certified ambient air monitoring 

data for the 2008–2010 period and data 

available to date for 2011, showing that 

the Area has monitored attainment of 

the 1997 annual PM2.5 NAAQS. If EPA 

finalizes this proposed determination of 

attainment, the requirements for the 

Area to submit an attainment 

demonstration and associated 

reasonably available control measures 

(RACM), a reasonable further progress 

(RFP) plan, contingency measures, and 

other planning State Implementation 

Plan (SIP) revisions related to the 

attainment of the standard shall be 

suspended for so long as the Area 

continues to attain the annual PM2.5

NAAQS. EPA is also proposing to 

determine, based on quality-assured and 

certified monitoring data for the 2007– 

2009 monitoring period, that the Area 

has attained the 1997 annual PM2.5

NAAQS by its applicable attainment 

date of April 5, 2010. These actions are 

being taken under the Clean Air Act 

(CAA).

SUPPLEMENTARY INFORMATION: 

Throughout this document, whenever 

‘‘we,’’ ‘‘us,’’ or ‘‘our’’ is used, we mean 

EPA. This supplementary information 

section is arranged as follows: 

I. What are the actions EPA is proposing? 

II. What is the background of these actions? 

III. What is EPA’s analysis of the relevant air 

quality data? 

IV. What are the effects of these actions? 

V. Statutory and Executive Order Reviews 

I. What are the actions EPA is 

proposing? 

In accordance with section 179(c)(1) 

of the CAA, 42 U.S.C. 7509(c)(1), and 40 

CFR 51.1004(c), EPA is proposing to 

determine that the Pittsburgh Area has 

attained the 1997 annual PM2.5 NAAQS. 

The proposal is based upon qualityassured and certified ambient air 

monitoring data for the 2008–2010 

monitoring periods and data available to 

date for 2011 that show that the 

Pittsburgh Area attained the 1997 

annual PM2.5 NAAQS. EPA is also 

proposing to determine, in accordance 

with EPA’s PM2.5 Implementation Rule 

of April 25, 2007 (72 FR 20664), that the 

Pittsburgh Area has attained the 1997 

annual PM2.5 NAAQS by its applicable 

attainment date of April 5, 2010, based 

upon quality-assured and certified 

ambient air monitoring data for the 

2007–2009 monitoring periods. 

II. What is the background of these 

actions? 

On July 18, 1997, EPA established an 

annual PM2.5 NAAQS at 15.0 

micrograms per cubic meter (mg/m3) 

(hereafter referred to as ‘‘the annual 

PM2.5 NAAQS’’ or ‘‘the annual 

standard’’), based on a 3-year average of 

annual mean PM2.5 concentrations (62 

FR 36852). At that time, EPA also 

established a 24-hour standard of 65 mg/ 

m3. See 40 CFR 50.7. The 1997 PM2.5

standards were based on significant 

evidence and numerous health studies 

demonstrating that serious health effects 

mstockstill on DSK4VPTVN1PROD with PROPOSALS

34298 Federal Register / Vol. 77, No. 112 / Monday, June 11, 2012 / Proposed Rules 

are associated with exposures to 

particulate matter. 

The process for designating areas 

following promulgation of a new or 

revised NAAQS is contained in section 

107(d)(1) of the CAA. On January 5, 

2005, EPA published its air quality 

designations and classifications for the 

1997 PM2.5 NAAQS based upon air 

quality monitoring data for calendar 

years 2001–2003 (70 FR 944). These 

designations became effective on April 

5, 2005. The Pittsburgh Area was 

designated nonattainment for the annual 

PM2.5 NAAQS during this designations 

process. The Pittsburgh Area is 

comprised of the counties of Beaver, 

Butler, Washington, and Westmoreland 

in their entireties, and portions of 

Allegheny, Armstrong, Greene, and 

Lawrence Counties. See 40 CFR 81.339 

(Pennsylvania). 

On October 17, 2006, EPA retained 

the annual PM2.5 NAAQS at 15.0 mg/m3

based on a 3-year average of annual 

mean PM2.5 concentrations and 

promulgated a new 24-hour standard of 

35 mg/m3 (the ‘‘2006 24-hour standard’’) 

based on a 3-year average of the 98th 

percentile of 24-hour concentrations (71 

FR 61144). On November 13, 2009, EPA 

designated the Pittsburgh Area as 

attainment for the 2006 24-hour 

standard (74 FR 58688). In that action, 

EPA also clarified the designations for 

the PM2.5 NAAQS promulgated in 1997 

stating that the Pittsburgh Area was 

attainment for the 1997 24-hour 

standard. Today’s action, however, does 

not address either the 1997 or the 2006 

24-hour standard. 

In response to legal challenges of the 

annual standards promulgated in 2006, 

the U.S. Court of Appeals for the District 

of Columbia Circuit (D.C. Circuit) 

remanded this standard to EPA for 

further consideration. See American 

Farm Bureau Federation and National 

Pork Producers Council, et al. v. EPA, 

559 F.3d 512 (D.C. Cir. 2009). However, 

given that the 1997 and 2006 annual 

standards are identical, attainment of 

the 1997 annual standard would also 

indicate attainment of the remanded 

2006 annual standard. 

On April 25, 2007, EPA promulgated 

its PM2.5 implementation rule, codified 

at 40 CFR part 51, subpart Z, in which 

EPA provided guidance for state and 

tribal plans to implement the 1997 PM2.5

NAAQS (72 FR 20664). This rule, at 40 

CFR 51.1004(c), specifies some of the 

regulatory consequences of attaining the 

standard, as discussed later. 

III. What is EPA’s analysis of the 

relevant air quality data? 

Today’s proposed rulemaking action 

determines that the Pittsburgh Area has 

met the annual PM2.5 NAAQS, based on 

the most recent three years of qualityassured data, and that the Area attained 

the annual PM2.5 NAAQS by its 

applicable attainment date of April 5, 

2010. Under EPA regulations at 40 CFR 

50.7, the annual primary and secondary 

PM2.5 standards are met when the 

annual arithmetic mean concentration, 

as determined in accordance with 40 

CFR part 50, appendix N, is less than or 

equal to 15.0 mg/m3 at all relevant 

monitoring sites in the subject area. 

EPA has determined that the PM2.5

monitoring network for the Pittsburgh 

Area is adequate. First, the number of 

monitors in the Area meets the 

minimum regulatory requirements given 

in 40 CFR part 58, appendix D. Second, 

the monitoring is in accordance with the 

monitoring plans that have been 

reviewed and approved by EPA. EPA 

has reviewed the quality-assured, 

quality-controlled, certified ambient air 

monitoring data recorded in the EPA’s 

AQS database for PM2.5 for the 

Pittsburgh Area from 2007–2009 and 

2009–2010, consistent with the 

requirements contained in 40 CFR part 

50. Preliminary PM2.5 data for 2011, 

which is not yet quality-assured and 

quality-controlled, was also reviewed. 

Table 1 shows the design values (i.e., 

the 3-year average of annual mean PM2.5

concentrations) for the annual PM2.5

NAAQS for the Pittsburgh Area 

monitors for the years 2007–2009. Table 

2 shows the design values for the annual 

PM2.5 NAAQS for the Pittsburgh Area 

monitors for the years 2008–2010. Table 

3 shows the air quality preliminary data 

available to date for 2011. EPA’s review 

of these data indicates that the 

Pittsburgh Area has met the annual 

PM2.5 NAAQS and that the Area 

attained the annual PM2.5 standard by 

its attainment date of April 5, 2010.

** No data available, since the monitor’s removal in January 1, 2011. 

While most of the monitoring data 

satisfy the data completeness 

requirement, monitoring sites ID 42– 

003–0093 (North Park) and ID 42–003– 

0095 (Moon) have missing data for the 

year 2008. To determine if the two 

monitors are in attainment with the 

annual PM2.5 NAAQS during the 

monitoring periods 2007–2009 and 

2008–2010, EPA has addressed the 

missing data by applying a recently 

developed statistical procedure. The 

diagnostic design values for the North 

Park and Moon monitors in the 

Pittsburgh Area were below the annual 

PM2.5 NAAQS level of 15.0 ug/m3. Thus, 

the results indicate that had the North 

Park and Moon monitors operated more 

days, the monitors would have attained 

the annual PM2.5 NAAQS during the 

monitoring periods 2007–2009 and 

2008–2010. Additional information 

about the monitoring network and air 

quality data used in this determination 

can be found in the Technical Support 

Document (TSD) for this action which is 

available online at www.regulations.gov, 

Docket number EPA–R03–OAR–2012– 

0370. 

IV. What are the effects of these 

actions? 

If EPA’s proposed determination of 

attainment based on the most recent 

three years of quality-assured data is 

made final, the requirements for the 

Pittsburgh Area to submit an attainment 

demonstration and associated RACM, 

RFP plan, contingency measures, and 

any other planning SIPs related to 

attainment of the annual PM2.5 NAAQS 

would be suspended for so long as the 

Pittsburgh Area continues to attain the 

annual PM2.5 NAAQS. See 40 CFR 

51.1004(c). Notably, as described below, 

any such determination would not be 

equivalent to the redesignation of the 

Pittsburgh Area to attainment for the 

annual PM2.5 NAAQS. If this proposed 

determination is finalized and EPA 

subsequently determines, after noticeand-comment rulemaking in the Federal 

Register, that the Area has violated the 

annual PM2.5 NAAQS, the basis for the 

suspension of the specific requirements 

would no longer exist for the Pittsburgh 

Area, and the Area would thereafter 

have to address the applicable 

requirements. See 40 CFR 51.1004(c). 

Finalizing this proposed action would 

not constitute a redesignation of the 

Area to attainment of the annual PM2.5

NAAQS under section 107(d)(3) of the 

CAA. Further, finalizing this proposed 

action does not involve approving a 

maintenance plan for the Pittsburgh 

Area as required under section 175A of 

the CAA, nor would it find that the Area 

has met all other requirements for 

redesignation. Even if EPA finalizes the 

proposed action, the designation status 

of the Pittsburgh Area would remain 

nonattainment for the annual PM2.5

NAAQS until such time as EPA 

determines that the Area meets the CAA 

requirements for redesignation to 

attainment and takes action to 

redesignate the Pittsburgh Area. In 

addition, if EPA’s separate and 

independent proposed determination 

that the Pittsburgh Area has attained the 

annual PM2.5 standard by its applicable 

attainment date (April 5, 2010) is 

finalized, EPA will have met its 

requirement pursuant to section 

179(c)(1) of the CAA to make a 

determination based on the Area’s air 

quality data as of the attainment date 

whether the Area attained the standard 

by that date. 

These two actions described above are 

proposed determinations regarding the 

Pittsburgh Area’s attainment only with 

respect to the annual PM2.5 NAAQS. 

Today’s actions do not address the 1997 

or the 2006 24-hour PM2.5 standards. 

EPA is soliciting public comments on 

the issues discussed in this document. 

These comments will be considered 

before taking final action. 

IV. Statutory and Executive Order 

Reviews 

Under the CAA, the Administrator is 

required to approve a SIP submission 

mstockstill on DSK4VPTVN1PROD with PROPOSALS

34300 Federal Register / Vol. 77, No. 112 / Monday, June 11, 2012 / Proposed Rules 

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 proposes to approve state law as 

meeting Federal requirements and does 

not impose additional requirements 

beyond those imposed by state law. For 

that reason, this proposed 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 (Public Law 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 proposed 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.

Instructions: Direct your comments to 

Docket ID No. EPA–R03–OAR–2012– 

0378. EPA’s policy is that all comments 

received will be included in the public 

docket without change, and may be 

made available online at 

www.regulations.gov, including any 

personal information provided, unless 

the comment includes information 

claimed to be Confidential Business 

Information (CBI) or other information 

whose disclosure is restricted by statute. 

Do not submit information that you 

consider to be CBI or otherwise 

protected through www.regulations.gov 

or email. The www.regulations.gov Web 

site is an ‘‘anonymous access’’ system, 

which means EPA will not know your 

identity or contact information unless 

you provide it in the body of your 

comment. If you send an email 

comment directly to EPA without going 

through www.regulations.gov, your 

email address will be automatically 

captured and included as part of the 

comment that is placed in the public 

docket and made available on the 

Internet. If you submit an electronic 

comment, EPA recommends that you 

include your name and other contact 

information in the body of your 

comment and with any disk or CD–ROM 

you submit. If EPA cannot read your 

comment due to technical difficulties 

and cannot contact you for clarification, 

EPA may not be able to consider your 

comment. Electronic files should avoid 

the use of special characters, any form 

of encryption, and be free of any defects 

or viruses. 

Docket: All documents in the 

electronic docket are listed in the 

www.regulations.gov index. Although 

listed in the index, some information is 

not publicly available, i.e., CBI or other 

information whose disclosure is 

restricted by statute. Certain other 

material, such as copyrighted material, 

is not placed on the Internet and will be 

publicly available only in hard copy 

form. Publicly available docket 

materials are available either 

electronically in www.regulations.gov or 

in hard copy during normal business 

hours at the Air Protection Division, 

U.S. Environmental Protection Agency, 

Region III, 1650 Arch Street, 

Philadelphia, Pennsylvania 19103.
