[EPA-R03-OAR-2011-0419; FRL-9445-1]


Approval and Promulgation of Air Quality Implementation Plans; 
Pennsylvania; Determinations of Attainment of the 1997 Fine Particle 
Standard for the Harrisburg-Lebanon-Carlisle, Johnstown, Lancaster, 
York, and Reading Nonattainment Areas

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

-----------------------------------------------------------------------

SUMMARY: EPA is taking direct final action to determine that the 
Harrisburg-Lebanon-Carlisle (Harrisburg), Johnstown, Lancaster, York, 
and Reading fine particle (PM2.5) nonattainment areas (the 
Areas) in the Commonwealth of Pennsylvania have attained the 1997 
annual PM2.5 National Ambient Air Quality Standard (NAAQS) 
by the applicable attainment date of April 5, 2010. These 
determinations are based upon complete, quality assured, and certified 
ambient air monitoring data that show the Areas monitored attainment of 
the 1997 annual PM2.5 NAAQS for the 2007-2009 monitoring 
period. EPA is finding these Areas to be in attainment in accordance 
with the requirements of the Clean Air Act (CAA).

DATES: This rule is effective on September 27, 2011 without further 
notice, unless EPA receives adverse written comment by August 29, 2011. 
If EPA receives such comments, it will publish a timely withdrawal of 
the direct final rules in the Federal Register and inform the public 
that the rules will not take effect.

IV. What are the effects of these actions?
V. Final Action
VI. Statutory and Executive Order Reviews

I. What actions are EPA taking?

    In accordance with section 179(c)(1) of the CAA, EPA is determining 
that the Harrisburg, Johnstown, Lancaster, York, and Reading 
PM2.5 nonattainment areas have attained the 1997 annual 
PM2.5 NAAQS by the applicable attainment date of April 5, 
2010 and in accordance with EPA's PM2.5 Implementation Rule 
of April 25, 2007 (72 FR 20664). These determinations are based upon 
complete, quality assured, and certified ambient air monitoring data 
from 2007-2009 that show the Areas monitored attainment of the 1997 
annual PM2.5 NAAQS during this monitoring period.

II. What is the background for these actions?

    On July 18, 1997 (62 FR 36852), EPA established a health-based 
PM2.5 NAAQS at 15.0 micrograms per cubic meter ([mu]g/m\3\) 
based on a 3-year average of annual mean PM2.5 
concentrations (hereafter referred to as ``the annual PM2.5 
NAAQS'' or ``the annual standard''). At that time, EPA also established 
a 24-hour standard of 65 [mu]g/m\3\ (the ``1997 24-hour standard''). 
See 40 CFR 50.7. On January 5, 2005 (70 FR 944), 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. These designations became effective on April 5, 2005. The 
Harrisburg, Johnstown, Lancaster, York, and Reading areas were 
designated nonattainment for the 1997 annual PM2.5 NAAQS 
during this designations process. See 40 CFR 81.339. The Harrisburg 
nonattainment area consists

[[Page 45425]]

of Cumberland, Dauphin, and Lebanon Counties. The Johnstown 
nonattainment area consists of Cambria County and the part of Indiana 
County which includes the Townships of West Wheatfield, Center, East 
Wheatfield, and Armagh Borough and Homer City Borough. The Lancaster 
nonattainment area consists of Lancaster County. The York nonattainment 
area consists of York County. The Reading nonattainment area consists 
of Berks County.
    On October 17, 2006 (71 FR 61144), EPA retained the 1997 annual 
PM2.5 NAAQS at 15 [mu]g/m\3\ based on a 3-year average of 
annual mean PM2.5 concentrations, and promulgated a 24-hour 
standard of 35 [mu]g/m\3\ based on a 3-year average of the 98th 
percentile of 24-hour concentrations (the ``2006 24-hour standard''). 
On November 13, 2009, EPA designated the Harrisburg-Lebanon-Carlisle-
York Area, the Johnstown Area, and the Lancaster Area as nonattainment 
for the 2006 24-hour standard (74 FR 58688). The Air Quality Control 
Region (AQCR) 151 Northeast Pennsylvania-Upper Delaware Valley 
Interstate area which includes Berks County (Reading) is designated as 
attainment for the 2006 24-hour standard (74 FR 58688). In that action, 
EPA also clarified that the designations for these Areas were 
attainment for the 1997 24-hour PM2.5 standard. Today's 
actions, however, do not address the 1997 or the 2006 24-hour 
PM2.5 standard.
    In response to legal challenges of the annual standard 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. Circuit 2009). However, 
given that the 1997 and 2006 annual PM2.5 standards are 
essentially identical, attainment of the 1997 annual standard would 
also indicate attainment of the remanded 2006 annual standard.
    EPA previously made clean data determinations related to the 1997 
annual PM2.5 NAAQS for each of these Areas pursuant to 40 
CFR 51.1004(c). A clean data determination was made for the Harrisburg 
Area on August 25, 2008 (73 FR 49949) and clean data determinations 
were made for the Johnstown, Lancaster, York, and Reading Areas on 
September 25, 2009 (74 FR 48863) and remain in effect.
    Under CAA section 179(c), EPA is required to make a determination 
that a nonattainment area has attained by its attainment date, and 
publish that determination in the Federal Register. The determination 
of attainment is not equivalent to a redesignation, and the state must 
still meet the statutory requirements for redesignation in order for 
the Areas to be redesignated to attainment. Complete, quality assured, 
certified PM2.5 air quality monitoring data recorded in the 
EPA Air Quality System (AQS) database for 2007 through 2009, show that 
the Harrisburg, Johnstown, Lancaster, York, and Reading, PA Areas 
attained the 1997 annual PM2.5 NAAQS by the applicable 
attainment date.

III. What is EPA's analysis of the relevant air quality data?

    EPA has reviewed the ambient air monitoring data for 
PM2.5, consistent with the requirements contained in 40 CFR 
part 50 and recorded in the EPA AQS database for the Harrisburg, 
Johnstown, Lancaster, York, and Reading nonattainment areas for the 
monitoring period from 2007 through 2009. On the basis of that review, 
EPA has concluded that the areas attained the 1997 annual 
PM2.5 NAAQS based on data for the 2007-2009 monitoring 
period.
    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 [mu]g/m\3\. The values 
calculated in accordance with 40 CFR part 50 Appendix N are referred to 
as design values, and these values are used to determine if an area is 
attaining the NAAQS. According to the PM2.5 implementation 
rule, the attainment date for these areas is April 5, 2010 and 
monitoring data from the period 2007 through 2009 is used to determine 
if the areas attained by April 5, 2010.
    EPA's review of the data indicate that the Harrisburg, Johnstown, 
Lancaster, York, and Reading nonattainment areas attained the annual 
1997 PM2.5 NAAQS by the applicable attainment date. The 
data, presented in Tables 1 through 5, are available at http://www.epa.gov/air/airtrends/values.html and can be found under the 
heading: Design Values 2007-2009, PM2.5 Design Values.
    Table 1 shows the PM2.5 design values for each monitor 
in the Harrisburg Area for the years 2007-2009. All 2007-2009 design 
values are below 15.0 [mu]g/m\3\ and all monitors meet the data 
completeness requirements. Therefore, the Harrisburg Area attained the 
1997 annual PM2.5 NAAQS by its attainment date.

IV. What are the effects of these actions?

    EPA is determining that the Harrisburg, Johnstown, Lancaster, York, 
and Reading Areas have attained the 1997 annual PM2.5 NAAQS 
by the applicable attainment date of April 5, 2010. Therefore, EPA has 
met the requirement pursuant to the CAA section 179(c) to make a 
determination based on the Areas' air quality data that the Areas 
attained the standard by the attainment date. Also, since the 
Harrisburg, Johnstown, Lancaster, York, and Reading Areas have attained 
the 1997 annual PM2.5 NAAQS by the applicable attainment 
date, the Areas are not subject to the consequences of failure to 
attain.
    These actions do not constitute a redesignation to attainment under 
section 107(d)(3) of the CAA. The designation status of the Harrisburg, 
Johnstown, Lancaster, York, and Reading Areas will remain nonattainment 
for the 1997 annual PM2.5 NAAQS until such time as EPA 
determines that the areas meet the CAA requirements for redesignation 
to attainment. Further, these actions do not involve approving 
maintenance plans for the Areas as required under section 175A of the 
CAA, nor do they find that the Areas have met all other requirements 
for redesignation. The designation status of the Harrisburg, Johnstown, 
Lancaster, York, and Reading Areas will remain nonattainment for the 
1997 annual PM2.5 NAAQS until such time as EPA determines 
that the Areas meet the CAA requirements for redesignation to 
attainment and take action to redesignate the Harrisburg, Johnstown, 
Lancaster, York, and Reading Areas.

V. Final Action

    Pursuant to section 179(c) of the CAA, EPA is determining that the 
Harrisburg, Johnstown, Lancaster, York, and Reading Areas attained the 
1997 annual PM2.5 NAAQS by the applicable attainment date of 
April 5, 2010. EPA is publishing this rule without prior proposal 
because the Agency views this as a noncontroversial action and 
anticipates no adverse comment.

[[Page 45427]]

However, in the ``Proposed Rules'' section of today's Federal Register, 
EPA is publishing a separate document that will serve as the proposal 
to determine these areas attained the 1997 annual PM2.5 
NAAQS by the applicable attainment date if adverse comments are filed. 
This rule will be effective on September 27, 2011 without further 
notice unless EPA receives adverse comment by August 29, 2011. If EPA 
receives adverse comment, EPA will publish a timely withdrawal in the 
Federal Register informing the public that the rule will not take 
effect. EPA will address all public comments in a subsequent final rule 
based on the proposed rule. EPA will not institute a second comment 
period on this action. Any parties interested in commenting must do so 
at this time. Please note that if EPA receives adverse comment on an 
amendment, paragraph, or section of these rules and if that provision 
may be severed from the remainder of the rules, EPA may adopt as final 
those provisions of the rules that are not the subject of an adverse 
comment.

VI. Statutory and Executive Order Reviews

A. General Requirements

    This action merely makes attainment determinations based on air 
quality data and does not impose any additional requirements. 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 these PM2.5 NAAQS attainment determinations 
do 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 these actions 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 rules in the Federal Register. A major rule 
cannot take effect until 60 days after it is published in the Federal 
Register. These actions are not ``major rules'' 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 these actions must be filed in the United States Court of Appeals 
for the appropriate circuit by September 27, 2011. Filing a petition 
for reconsideration by the Administrator of these final rules 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. Parties with objections to these direct final rules are 
encouraged to file a comment in response to the parallel notice of 
proposed rulemaking for these actions published in the proposed rules 
section of today's Federal Register, rather than file an immediate 
petition for judicial review of these direct final rules, so that EPA 
can withdraw these direct final rules and address the comment in the 
proposed rulemakings. These actions, to determine that the Harrisburg, 
Johnstown, Lancaster, York, and Reading Areas attained the 1997 annual 
PM2.5 NAAQS by the applicable attainment date of April 5, 
2010, may not be challenged later in proceedings to enforce its 
requirements. (See section 307(b)(2).)

determined that the Harrisburg PM2.5 nonattainment area is 
not subject to the consequences of failing to attain pursuant to 
section 179(d).
    (b) Based upon EPA's review of the air quality data for the 3-year 
period 2007 to 2009, EPA determined that the Johnstown fine particle 
(PM2.5) nonattainment area attained the 1997 annual 
PM2.5 National Ambient Air Quality Standard (NAAQS) by the 
applicable attainment date of April 5, 2010. Therefore, EPA has met the 
requirement pursuant to CAA section 179(c) to determine, based on the 
area's air quality as of the attainment date, whether the area attained 
the standard. EPA also determined that the Johnstown PM2.5 
nonattainment area is not subject

period 2007 to 2009, EPA determined that the York fine particle 
(PM2.5) nonattainment area attained the 1997 annual 
PM2.5 National Ambient Air Quality Standard (NAAQS) by the 
applicable attainment date of April 5, 2010. Therefore, EPA has met the 
requirement pursuant to CAA section 179(c) to determine, based on the 
area's air quality as of the attainment date, whether the area attained 
the standard. EPA also determined that the York PM2.5 
nonattainment area is not subject to the consequences of failing to 
attain pursuant to section 179(d).
    (e) Based upon EPA's review of the air quality data for the 3-year 
period 2007 to 2009, EPA determined that the Reading fine particle 
(PM2.5) nonattainment area attained the 1997 annual
