Air Quality Designations for the 2006 24-Hour Fine Particle 
(PM2.5) National Ambient Air Quality Standards

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: This rule establishes the initial air quality designations for 
most areas in the United States (U.S.), including Indian Country, for 
the 2006 24-hour fine particle (PM2.5) National Ambient Air 
Quality Standards (NAAQS). Through these designations, EPA is 
identifying areas that meet or violate these NAAQS. In particular, EPA 
is identifying the geographic boundaries of areas that violate, or 
contribute to violations of, the 2006 24-hour PM2.5 NAAQS. 
This is an important step toward providing the public health and 
welfare protections of the 2006 24-hour PM2.5 NAAQS. The 
Clean Air Act (CAA) requires states with areas designated nonattainment 
to undertake certain planning and pollution control activities within 
these areas in order to attain the standards as quickly as reasonably 
possible. Designating areas also helps citizens know whether the air 
quality where they live and work is healthful or unhealthful. Health 
studies have shown significant associations between exposure to 
PM2.5 and premature death from heart and lung disease. 
PM2.5 can also aggravate heart and lung diseases and has 
been linked to effects such as cardiovascular symptoms, cardiac 
arrhythmias, heart attacks, respiratory symptoms, asthma attacks, and 
bronchitis. These effects can result in increased hospital admissions, 
emergency room visits, absences from school or work, and restricted 
activity days. Individuals that may be particularly sensitive to 
PM2.5 exposure include people with heart or lung disease, 
older adults, and children.

DATES: Effective Date: The effective date of this rule is December 14, 
2009.

II. What Is the Purpose of This Document?

    The purpose of this document is to announce and promulgate initial 
designations and boundaries for areas across the country with respect 
to the 2006 24-hour PM2.5 NAAQS, in accordance with the 
requirements of CAA section 107(d). The list of areas in each state and 
in Indian Country, and the designation for each area, appear in the 
table at the end of this final rule (amendments to 40 CFR 81.300-356). 
For those areas designated nonattainment, states must develop a State 
Implementation Plan (SIP) and tribes may develop a Tribal 
Implementation Plan that provides for attainment of the NAAQS as 
expeditiously as practicable, in accordance with the requirements of 
the CAA and applicable EPA regulations. Pursuant to section 172(b), EPA 
is announcing that states and tribes must submit these plans no later 
than three years from the effective date of these designations. Such 
plans must meet the requirements of section 172(c). EPA's current 
implementation regulations for PM2.5 at 40 CFR section 
51.1000-1012 apply expressly only to the 1997 PM2.5 NAAQS. 
EPA is considering amending those regulations explicitly to encompass 
the 2006 PM2.5 NAAQS, and whether any other revisions to the 
regulations are necessary for these new standards. The Agency 
anticipates that the SIP requirements for the 2006 PM2.5 
NAAQS should be comparable to those for the 1997 PM2.5 
NAAQS, so that the regulations at sections 51.1000-1012 can be used as 
a guide to SIP planning for the 2006 NAAQS pending any revisions to the 
regulations. For those areas designated unclassifiable or attainment, 
states must meet other statutory and regulatory requirements to prevent 
significant deterioration of air quality in those areas.
    This notice identifies the 31 areas, listed in Table 1 below, 
comprised of one or more whole or partial counties, as nonattainment 
areas for the 2006 24-hour PM2.5 NAAQS. The basis for 
establishing these areas as ``nonattainment'' is monitored air quality 
data for 2006-2008 indicating a violation of the NAAQS. EPA has also 
identified three additional areas with monitoring data now indicating 
potential violations of the 2006 24-hour PM2.5 NAAQS, and we 
are in the process of working with affected states and tribes in 
accordance with CAA section 107(d) to establish nonattainment 
boundaries for these areas. Accordingly, EPA is deferring the 
designations for these areas until EPA and the states and tribes can 
develop sufficient information to determine the appropriate boundaries 
for these nonattainment areas. Table 3 below identifies these areas.
    EPA completed initial designations for the annual PM2.5 
NAAQS in 2005 (70 FR 944). EPA's review of 2006-2008 monitoring data 
indicates that two areas initially designated as ``unclassifiable/
attainment'' for the annual PM2.5 NAAQS are now violating 
that NAAQS. For these two areas, EPA intends to initiate the process to 
redesignate these currently violating areas to nonattainment in 
accordance with the procedures of CAA section 107(d)(3). The outcome of 
the redesignation process will be announced in a separate future 
notice.
    This rule also lists the current designations for the 1997 24-hour 
PM2.5 NAAQS designations, which remain in place. EPA has not 
previously, and is not by this action, revoking the 1997 annual or 24-
hour PM2.5 NAAQS. Areas currently designated nonattainment 
for the 1997 annual or 24-hour NAAQS remain so after this action, and 
remain obligated to comply with the statutory and regulatory 
requirements applicable to such areas. EPA is not by this action

[[Page 58690]]

promulgating any designations for the 1997 PM2.5 NAAQS, but 
is announcing its intention to initiate the redesignation process under 
CAA section 107(d)(3) by a later action.

III. What Are Fine Particles and the Health Concerns Associated With 
Fine Particles?

    Fine particles are extremely small airborne particles. Airborne 
particles with a nominal aerodynamic diameter of 2.5 micrometers or 
less (a micrometer is one-millionth of a meter; 2.5 micrometers is less 
than about one-thirtieth the thickness of a human hair) are considered 
to be ``fine particles'' and are also known as PM2.5. Due to 
their small size, they can penetrate deeply into the lungs of people 
who inhale them, where they can accumulate, react, or be absorbed into 
the body. Epidemiological studies have shown a significant association 
between elevated PM2.5 levels and a number of serious health 
effects, including premature mortality, aggravation of respiratory and 
cardiovascular disease (as indicated by increased hospital admissions, 
emergency room visits, absences from school or work, and restricted 
activity days), lung disease, decreased lung function, asthma attacks, 
and certain cardiovascular problems such as heart attacks and cardiac 
arrhythmia. Individuals particularly sensitive to PM2.5 
exposure include older adults, people with heart and lung disease, and 
children.
    Fine particles in the atmosphere are made up of a complex mixture 
of components, both liquid and solid. Common constituents of ambient 
PM2.5 include: Sulfate (SO4); nitrate 
(NO3); ammonium (NH4); elemental carbon; a great 
variety of organic compounds; and inorganic material (including metals, 
dust, sea salt, and other trace elements), which often is referred to 
as ``crustal'' material. Ambient PM2.5 is typically 
comprised of a mixture of primary and secondary particles. ``Primary'' 
particles are emitted directly into the air as a solid or liquid 
particle (e.g., elemental carbon and organic particles from diesel 
engines or burning activities). ``Secondary'' particles (e.g., 
SO4 and NO3) form in the atmosphere as a result 
of various chemical transformations of gaseous precursors such as 
sulfur dioxide (SO2) and oxides of nitrogen 
(NOX). These primary and secondary particles result from a 
broad variety of sources and emissions activities. Chemical precursors 
to secondary particles include SO2, NOX, volatile 
organic compounds (VOCs), and ammonia.
    Fine particles are emitted by, and formed from emissions of, a wide 
range of sources. For example, SO4 particles usually result 
from reactions of SO2 emissions (from sources like power 
plants and industrial boilers) with ammonia emissions (from sources 
like animal feeding operations and fertilizer production, and to a 
lesser extent from mobile sources and power plants). Nitrate particles 
usually result from reactions of NOX emissions (from such as 
mobile sources, power plants, or other industrial sources) with ammonia 
emissions. Crustal particles typically result from sources or 
activities that cause suspension of soils or metals in the air, such as 
re-entrained road dust, agriculture, or mining. Carbonaceous particles 
result from emissions from a wide range of sources or activities that 
cause the suspension of soil or metals in the air, such as re-entrained 
road dust, agriculture, or mining. Carbonaceous particles emanate 
directly from diesel and gasoline powered engines in mobile sources and 
heavy equipment, wildfires, waste burning, power generation, and other 
industrial sources. They also result from secondary reactions of VOCs 
in the atmosphere. Speciated data for PM2.5 can provide 
information useful in identifying contributing emission sources and 
areas.
    The relative proportion of primary and secondary particles, and the 
relative proportions of different species of particles found in a given 
geographic area, can vary widely, depending upon factors such as the 
mix of sources in the area, the mix of PM2.5 precursors, and 
meteorology. The sources of PM2.5 and PM2.5 
precursors in any area also vary by type, amount, and number. Thus, the 
ambient PM2.5 in areas results from complex interaction of 
emissions that, in the aggregate, comprise the total ambient 
PM2.5 level.
    Additionally, PM2.5 and its precursors can transport 
hundreds or thousands of miles suspended in the atmosphere. The extent 
and direction of transport are affected by meteorological conditions 
and winds. Wind direction, speed, and strength all vary over the course 
of a single day, as well as by season, and, thus, over the entire year. 
Consequently, ambient PM2.5 in an area may be the 
combination of primary and secondary PM2.5 particles that 
result from the emissions of sources in that area, nearby areas, and 
areas much farther away.
    Given the complex nature of PM2.5, including its serious 
adverse health impacts, multiple precursors, numerous sources, 
meteorological considerations, and the need to distinguish between 
impacts of local and non-local sources at any violating monitor, EPA 
has developed a case-by-case approach to determining designations for 
PM2.5. In particular, to determine which areas are 
violating, and which nearby areas are contributing to those violations, 
EPA considers the specific facts and circumstances of each area.

IV. What Air Quality Standards Has EPA Established To Address Fine 
Particles?

    On July 18, 1997, EPA revised the NAAQS for particulate matter to 
add new standards for fine particle pollution, using PM2.5 
as the indicator. EPA established annual and 24-hour standards for 
PM2.5 (62 FR 38652). The primary and secondary annual 
PM2.5 standards were set at a level of 15 micrograms per 
cubic meter ([mu]g/m\3\), based on a 3-year average of annual mean 
PM2.5 concentrations. The primary and secondary 24-hour 
PM2.5 standards were set at a level of 65 [mu]g/m\3\, based 
on a 3-year average of the 98th percentile of 24-hour PM2.5 
concentrations. The 1997 annual and 24-hour PM2.5 NAAQS are 
codified at 40 CFR section 50.7. EPA promulgated the designations for 
the 1997 PM2.5 NAAQS on January 5, 2005, and these 
designations became effective on April 5, 2005 (70 FR 944). The U.S. 
Court of Appeals for the District of Columbia has recently upheld EPA's 
designations for the 1997 PM2.5 NAAQS for all but one 
area.\1\
---------------------------------------------------------------------------

    \1\ See, Catawba et al. v. EPA, No. 05-1064 and consolidated 
cases, decided July 7, 2009.
---------------------------------------------------------------------------

    In 2006, EPA strengthened the primary and secondary 24-hour 
PM2.5 NAAQS from 65 [mu]g/m\3\ to 35 [mu]g/m\3\, and 
retained the current primary and secondary annual PM2.5 
NAAQS at 15 [mu]g/m\3\. The revised 24-hour PM2.5 standards 
were published on October 17, 2006 (71 FR 61144) and became effective 
on December 18, 2006. The 2006 annual and 24-hour PM2.5 
NAAQS are codified at 40 CFR 50.13. The more stringent 2006 24-hour 
PM2.5 standards are based on significant evidence and 
numerous health studies demonstrating that serious health effects are 
associated with short-term exposures to PM2.5 at this level.
    Many petitioners challenged EPA's 2006 annual PM2.5 
standards but not the 2006 24-hour PM2.5 standards. As a 
result of that challenge, the U.S. Court of Appeals for the District of 
Columbia has remanded the 2006 annual PM2.5 standards to EPA 
for further proceedings.\2\ Though remanded, the standards remain in 
effect while EPA determines how to respond to the concerns raised in 
the court's opinion.

[[Page 58691]]

EPA is currently evaluating a petition concerning the designations for 
the 2006 annual PM2.5 standards and is not promulgating them 
at this time. Because the 2006 24-hour PM2.5 NAAQS are in 
effect and the court did not remand them, EPA is proceeding to 
promulgate the designations for these standards in this rulemaking 
action.

Producers Council, et al. v. EPA, 559 F.3d 512 (DC Cir. 2009).

V. What Are the Clean Air Act (CAA) Requirements for Air Quality 
Designations?

    This section summarizes the provisions of section 107(d) of the 
CAA, which governs the process that the states and EPA must follow in 
order to promulgate designations. Section 107(d)(1) provides that, 
after EPA promulgates any new or revised NAAQS, EPA must promulgate 
designations for all areas nationwide through a specific administrative 
process governed by the terms of section 107(d). The designations 
process is explicitly exempt from the usual notice and comment 
procedures required by the Administrative Procedures Act (APA) pursuant 
to section 107(d)(2)(B). The process is likewise exempt from the 
procedural requirements of section 307(d), unless EPA invokes it, by 
virtue of the fact that designations are not included in the statutory 
list of actions in section 307(d)(1).\3\
---------------------------------------------------------------------------

    \3\ This view has been confirmed in Catawba et al. v. EPA, No. 
05-1064 and consolidated cases, decided July 7, 2009.
---------------------------------------------------------------------------

    The designation process begins with initial recommendations for 
designations from the states and tribes for areas within their 
jurisdictions. Section 107(d)(1)(A) provides that, by not later than 
one year after promulgation of a new or revised standard, each state is 
required to submit its recommendations for air quality designations for 
all areas under its jurisdiction to EPA, including the appropriate 
boundaries for nonattainment areas. Within section 107(d)(1)(A), the 
CAA establishes three types of designations: (i) Attainment areas that 
meet the NAAQS; (ii) unclassifiable areas, for which there is 
insufficient information to determine whether or not the area meets the 
NAAQS; and (iii) nonattainment areas that either do not meet the NAAQS, 
or that contribute to violations in a nearby area that does not meet 
the NAAQS. With respect to nonattainment areas, it should be noted that 
the statute does not define what constitutes a violation of the NAAQS. 
Nor does the statute define the terms ``area,'' ``contributes,'' or 
``nearby'' for purposes of designations for any NAAQS.
    EPA reviews state recommendations and, under section 107(d)(1)(B), 
is authorized to make any modifications to those recommendations that 
the Administrator deems necessary. The statute does not define the term 
``necessary,'' but EPA interprets this to authorize the Administrator 
to modify designations that did not meet the statutory requirements or 
were otherwise inconsistent with the facts or analysis deemed 
appropriate by EPA. If EPA is considering modifications to a state's 
initial recommendation, EPA is required to notify the state of any such 
intended modifications to its recommendation not less than 120 days 
prior to EPA's promulgation of the final designation. If the state does 
not agree with EPA's modification, it then has an opportunity to 
respond to EPA and to demonstrate why it believes the modification 
proposed by EPA is inappropriate, as contemplated by section 
107(d)(1)(B)(ii). Even if a state fails to provide any recommendation 
for an area, in whole or in part, EPA still must promulgate a 
designation that the Administrator deems appropriate, pursuant to 
section 107(d)(1)(B)(ii).
    Section 107(d)(1)(B)(i) directs EPA to promulgate the designations 
as expeditiously as practicable, but not later than two years from the 
date of promulgation of new or revised air quality standards. However, 
in the event that EPA has insufficient information to promulgate the 
designation for an area, EPA may extend the period for up to one 
additional year.
    EPA believes that section 107(d) provides the Agency with 
discretion to determine how best to interpret the terms in the 
definition of a nonattainment area (e.g., ``contributes to'' and 
``nearby'') for a new or revised NAAQS, given considerations such as 
the nature of a specific pollutant, the types of sources that may 
contribute to violations, the form of the standards for the pollutant, 
and other relevant information. In particular, EPA believes that the 
statute does not require the Agency to establish bright line tests or 
thresholds for what constitutes contribution or nearby for purposes of 
designations.\4\
---------------------------------------------------------------------------

    \4\ This view has been confirmed in Catawba et al. v. EPA, No. 
05-1064 and consolidated cases, decided July 7, 2009.
---------------------------------------------------------------------------

    Similarly, EPA believes that the statute permits EPA to evaluate 
the appropriate application of the term ``area'' to include geographic 
areas based upon full or partial county boundaries, and contiguous or 
non-contiguous areas, as may be appropriate for a particular NAAQS. For 
example, section 107(d)(1)(B)(ii) explicitly provides that EPA can make 
modifications to designation recommendations for an area ``or portions 
thereof,'' and under section 107(d)(1)(B)(iv), a designation remains in 
effect for an area ``or portion thereof'' until EPA redesignates it. 
See footnote 4.
    Section 107(d) contains additional specific provisions applicable 
to other NAAQS, such as ozone or lead in section 107(d)(4) and (5). The 
designations for the 2006 24-hour PM2.5 NAAQS are governed 
by the general provisions of section 107(d)(1) and (2). However, EPA 
has concluded that it has discretion to look to other provisions of 
section 107(d) by analogy, as appropriate, to inform the process for 
designations for the 2006 24-hour PM2.5 NAAQS. See footnote 
4. For example, EPA recommended that states assess boundaries for 
nonattainment areas using information related to various factors 
similar to those that EPA had previously recommended for the 1997 
annual PM2.5 NAAQS designations, and which, in turn, relate 
to similar types of information that Congress provided for 
consideration in designations for ozone in section 107(d)(4)(A)(v). See 
footnote 4.
    Another key distinction of section 107(d) is that it directs EPA to 
identify areas that violate the NAAQS, and nearby areas that 
``contribute'' to those violations. Some have asserted that this term 
should be controlled by EPA's interpretation of comparable terms in 
section 110(a)(2)(D) and section 126. In other actions, such as the 
Clean Air Interstate Rule, EPA has relied on the term ``contribute 
significantly to nonattainment'' to support regulatory efforts to 
address regional interstate transport of pollutants, such as 
SO2 and NOX, that exacerbate nonattainment of the 
PM2.5 NAAQS in downwind areas. In these actions, EPA has, 
through regulation, evaluated amounts of emissions that occur on a 
statewide basis, and EPA has used this information to develop a 
threshold to determine which states should be considered to contribute 
significantly to nonattainment in another state, at a level sufficient 
to require inclusion within a regional control strategy.
    EPA believes that the explicit wording of section 107(d) and 
section 110(a)(2)(D) differs markedly, and that the purposes of the two 
provisions are likewise distinct. For example, EPA believes that 
section 110(a)(2)(D) requires some quantification of the amount of 
transport from a state, because the provision directs EPA to insure 
that there are provisions to

[[Page 58692]]

prevent emissions ``in amounts'' that would ``significantly'' 
contribute to violations of a NAAQS in another state. By comparison, 
section 107(d) includes no such explicit requirement for any 
quantification of emissions or contribution and does not use the term 
``significant'' to modify the word ``contributes.'' Moreover, section 
107(d) is intended to accomplish a distinctly different purpose from 
section 110(a)(2)(D). Section 107(d) directs EPA to identify those 
areas that are violating, and those nearby areas that are contributing 
to the violations, as the geographic areas within which states must 
address local emission sources for purposes of local attainment needs, 
in accordance with the requirements of section 172 and applicable 
regulations. By contrast, section 110(a)(2)(D) authorizes EPA to take 
action to address interstate transport of pollutants from one or more 
states that affect other states. To be sure, these provisions can work 
in concert to address the local and regional components of 
nonattainment for a given NAAQS. They are not, however, identical in 
wording or purpose.
    Designation activities for federally-recognized tribes are covered 
under the authority of section 301(d) of the CAA. This provision of the 
CAA authorizes EPA to treat eligible tribes in a similar manner as 
states. Pursuant to section 301(d)(2), EPA promulgated regulations, 
known as the Tribal Authority Rule (TAR) (63 FR 7254). The TAR is 
codified at 40 CFR part 49. That rule specifies those provisions of the 
CAA for which it is appropriate to treat tribes in a similar manner as 
states. Under the TAR, tribes may choose to develop and implement their 
own CAA programs, but are not required to do so. The TAR also 
establishes procedures and criteria by which tribes may request from 
EPA a determination of eligibility for such treatment.
    The designations process contained in section 107(d) of the CAA is 
included among those provisions determined to be appropriate by EPA for 
treatment of tribes in the same manner as states. Under the TAR, tribes 
generally are not subject to the same submission schedules imposed by 
the CAA on states. However, EPA itself is required to meet statutory 
deadlines for promulgation of designations and must observe those 
deadlines, notwithstanding the discretion EPA has to adjust schedules 
for tribes. As authorized by the TAR, tribes may seek eligibility to 
submit designation recommendations to EPA. In addition, CAA section 
301(d)(4) gives EPA discretionary authority, in cases where it 
determines that treatment of tribes as identical to states is 
``inappropriate or administratively infeasible,'' to provide for direct 
administration by regulation to achieve the appropriate purpose.
    To date, one tribe has applied for eligibility under the TAR to 
submit its own initial designation recommendations under section 
107(d)(1). Nonetheless, EPA invites all tribes to submit designation 
recommendations for new NAAQS. EPA works closely with tribes that 
request an opportunity to submit designation recommendations and 
supporting documentation. EPA reviews and acts on recommended 
designations in consultation with the tribes, and as with states, makes 
modifications to tribal recommendations as EPA deems necessary.

VI. How Did EPA Comply With the Clean Air Act (CAA) Requirements for 
Air Quality Designations?

    Following the December 18, 2006 effective date of the 2006 
PM2.5 NAAQS, EPA invited all states and tribes to submit 
area and boundary recommendations within one year. On June 8, 2007, EPA 
provided guidance making recommendations concerning various aspects of 
the designations, including timing, process, and factors reflecting the 
types of information that could be relevant to the evaluation of a 
specific area.\5\
---------------------------------------------------------------------------

    \5\ See, Memorandum from Robert J. Meyers, Acting Assistant 
Administrator, to EPA Regional Administrators--Regions I-X, ``Area 
Designations for the Revised 24-Hour Fine Particle National Ambient 
Air Quality Standard,'' June 8, 2007.
---------------------------------------------------------------------------

    Most states, and those tribes who elected to do so, submitted 
initial designation recommendations and supporting documentation to EPA 
by December 18, 2007.\6\ In general, state and tribal area 
recommendations were based on Federal Reference Method pair quality 
monitoring data from the 2004-2006 time period.\7\ After reviewing and 
evaluating each of these recommendations, EPA provided responses to the 
states and tribes on August 19-20, 2008. In these letters, EPA 
indicated whether or not EPA intended to make modifications to the 
initial state or tribal recommendations and explained EPA's reasons for 
suggesting any such modifications. As part of this process, EPA 
incorporated consideration of the most recent air quality data then 
available, for the 2005-2007 time period. EPA requested that states and 
tribes respond to any proposed EPA modifications to their initial 
recommendations by October 20, 2008.
---------------------------------------------------------------------------

    \6\ At this time, one tribe has applied for eligibility under 
the TAR to submit recommendations formally under section 107(d)(1). 
Nonetheless, EPA solicited and received submittals from tribes 
containing recommendations regarding EPA's designations for Indian 
country. For convenience, EPA will refer to these submittals as 
``recommendations'' in this notice.
    \7\ At each of these stages of the process, states, tribes and 
EPA have used the three most recent full calendar years of air 
quality monitoring data then available. By regulation, states and 
tribes must submit fully quality assured air quality monitoring data 
for a calendar year to EPA by July of the following year. Hence, at 
the time of the initial recommendations, 2004-2006 was the most 
recent set of data; at the time of EPA's consideration of those 
recommendations, 2005-2007 was the most recent set of data; at the 
time of these designations, 2006-2008 is the most recent set of 
data.
---------------------------------------------------------------------------

    Although not required by section 107(d) of the CAA, EPA also 
provided an opportunity for comment by members of the public in order 
to gather additional information for EPA to consider before making 
final designations.\8\ EPA published a notice on September 2, 2008 (73 
FR 51259) which invited the public to comment on EPA's intended 
designations. In this notice, EPA offered a 30-day comment period to 
all interested parties, other than states and tribes, as they already 
have statutorily provided opportunities to participate in the 
designations process. EPA posted the state and tribal initial 
recommendations and EPA's responses, including suggested modifications, 
on a Web site which was accessible to the public to provide information 
to inform their comments: (http://www.epa.gov/pmdesignations/
2006standards/index.htm). Timely comments from the public, and EPA's 
responses to significant public comments, are in the docket for this 
action.
---------------------------------------------------------------------------

    \8\ EPA did not elect to invoke section 307(d) for these 
designations. Pursuant to section 107(d)(2)(B), EPA may elect to use 
a notice and comment process as part of the designations process for 
a given NAAQS at the Agency's discretion. In this instance, EPA 
concluded that this extra process could provide additional helpful 
information. Normally, members of the public could of course express 
their views through the states and tribes who have a formal role in 
the designations process provided in section 107(d).
---------------------------------------------------------------------------

    The Agency received letters from many states and tribes suggesting 
changes to EPA's proposed modifications and providing additional 
information. EPA evaluated each letter and all of the timely technical 
support information that was provided before arriving at the final 
designation decisions. Some of the final designations reflect EPA's 
modifications to the initial state and tribal recommendations. Some 
reflect changes to EPA's suggested modifications, based upon 
information that states and tribes subsequently provided in response. 
Through this iterative process, EPA

[[Page 58693]]

developed the information necessary to inform the final designations 
decisions.
    On December 22, 2008, then EPA Administrator Johnson signed a 
notice concerning the designations for the 2006 24-hour 
PM2.5 NAAQS, and the notice was made available to the public 
on the EPA Web site at that time. However, that signed notice was never 
published in the Federal Register and, therefore, designations were not 
officially promulgated. Section 107(d)(2)(A) requires EPA to publish 
the notice in the Federal Register in order to promulgate designations. 
The December 2008 notice was awaiting publication in January 2009 when 
the newly-elected Administration identified the notice as one that 
should receive additional review before publication.\9\
---------------------------------------------------------------------------

    \9\ See, ``Memorandum For The Heads of Executive Departments and 
Agencies,'' from Rahm Emanuel, Assistant to the President and Chief 
of Staff, dated January 20, 2009.
---------------------------------------------------------------------------

    Since January 2009, EPA has thus been reviewing the designation 
decisions for the 2006 24-hour PM2.5 NAAQS. Three 
significant events have occurred in the interim that relate to the 
designations. First, the U.S. Court of Appeals for the District of 
Columbia issued its opinion in the litigation challenging EPA's 2006 
annual PM2.5 NAAQS.\10\ This decision resulted in, among 
other things, a remand of the annual standards to EPA for further 
consideration, but did not affect the 2006 24-hour PM2.5 
NAAQS. Second, monitoring data for 2008 has now become available for 
areas across the U.S. Accordingly, EPA has had the opportunity to 
evaluate whether data from 2006-2008 would result in previously 
violating areas now attaining the NAAQS, or previously attaining areas 
now violating the NAAQS. Third, the U.S. Court of Appeals for the 
District of Columbia issued its opinion in the litigation challenging 
EPA's 2005 designations for the 1997 annual PM2.5 NAAQS.\11\ 
In that decision, the court has affirmed EPA's interpretation of 
section 107(d) and general approach to promulgating designations for 
that NAAQS. The final designations that EPA will promulgate through 
publication of this rule have been informed by these more recent 
events.

Producers Council, et al. v. EPA, 559 F.3d 512 (DC Cir. 2009).

cases, decided July 7, 2009.
---------------------------------------------------------------------------

    EPA has already received a number of petitions concerning the 
designations for the 2006 24-hour PM2.5 NAAQS. Of these, two 
in particular require specific discussion because of the significant 
issues they raise. The first petition, from the American Lung 
Association and other groups, requests that EPA take action to 
promulgate designations for the 2006 annual PM2.5 NAAQS.\12\ 
EPA is currently evaluating that petition and will determine later 
whether to grant or deny it. In the meantime, however, EPA's review of 
the 2006-2008 monitoring data indicates that two areas currently 
designated as ``unclassifiable/attainment'' for the 1997 annual 
PM2.5 NAAQS are now violating that NAAQS. For these two 
areas, EPA intends to initiate the process to redesignate these areas, 
including both violating and contributing areas, to nonattainment in 
accordance with the procedures of CAA section 107(d)(3), as 
appropriate.

    The second petition, from the Environmental Defense Fund and other 
groups, requests that EPA delay or reconsider designations for 
attainment areas that contain heavily travelled roadways because the 
monitoring network in such areas may not adequately reflect near-
roadway exposure to PM2.5.\13\ EPA will respond to this 
petition separately in more detail, but believes that it is not 
appropriate to delay designations for the 2006 24-hour PM2.5 
NAAQS further, based on the concerns raised by these petitioners. EPA 
intends to evaluate the issues raised by these petitioners in the 
context of the ongoing review of the PM2.5 NAAQS and the 
associated monitoring regulations.

VII. How Did EPA Apply the Statutory Requirements and Applicable 
Guidance To Determine Nonattainment Area Designations and Boundaries 
for the 2006 24-Hour PM2.5 NAAQS?

    Section 107(d)(1)(A)(i) of the CAA defines a nonattainment area as 
any area that does not meet an ambient air quality standard, or that 
contributes to ambient air quality in a nearby area that does not meet 
the standard. If an area meets either prong of this definition, then 
EPA is required to designate the area as ``nonattainment.'' In June 
2007, EPA issued guidance concerning how to determine boundaries for 
nonattainment areas for the 2006 24-hour PM2.5 NAAQS (the 
2007 Guidance).\14\ As part of the 2007 Guidance, EPA recommended that 
the three most recent calendar years of air quality monitoring data for 
PM2.5 be used to identify a violation of the 2006 24-hour 
PM2.5 NAAQS. This is appropriate because the form of the 24-
hour PM2.5 NAAQS is calculated over a 3-year period. For the 
final designations, EPA has identified violating monitors based on air 
quality monitoring data from Federal Reference Method (FRM) monitors 
for calendar years 2006-2008.
---------------------------------------------------------------------------

    \14\ See, ``Area Designations for the Revised 24-Hour Fine 
Particle National Ambient Air Quality Standards,'' memorandum to 
Regional Administrators, Regions I-X, from Robert J. Meyers, Acting 
Assistant Administrator, OAR, dated June 8, 2007.
---------------------------------------------------------------------------

    By definition, areas may need to be designated nonattainment 
because they contribute to violations in another nearby area, even if 
they do not themselves have a monitor with violating data, or even if 
they do not have any monitor at all. As a result, states, tribes, and 
EPA need to consider additional relevant information in order to assess 
contributing areas as part of identifying the appropriate boundaries 
for nonattainment areas. Thus, in the 2007 Guidance, EPA recommended 
nine factors that pertained to types of information that EPA considered 
relevant for designations, and indicated that it would evaluate these 
factors along with any other relevant information or circumstances 
specific to a particular area, in determining appropriate nonattainment 
area boundaries.
    EPA also noted in the 2007 Guidance that, in making boundary 
recommendations for nonattainment areas, states and tribes should 
evaluate each area on a case-by-case basis. EPA intentionally did not 
attempt to create any bright line test or threshold for any factor or 
form of information. EPA believes that section 107(d) does not require 
any such bright lines or thresholds to determine contribution, and that 
to create one could result in over-inclusion or under-inclusion of 
areas in nonattainment areas, as compared to a more robust and fact-
specific analysis of each area on its merits. This approach is 
especially appropriate for PM2.5, given the multiple 
precursors, numerous sources, meteorological considerations, and need 
to distinguish between impacts of local and non-local sources at any 
given violating monitor.
    Finally, EPA indicated that it would promulgate nonattainment area 
boundaries that cover a sufficiently large area to include both the 
area that violates the standard and the nearby areas that contribute to 
the violations, as required by section 107, to assure that 
nonattainment area plans developed for

[[Page 58694]]

these areas would attain the NAAQS as expeditiously as practicable. 
Unlike the guidance for the 1997 PM2.5 NAAQS designations, 
EPA did not recommend the metropolitan area boundaries established by 
the U.S. Office of Management and Budget (OMB) as a rebuttable 
presumption for designations for the 2006 24-hour PM2.5 
NAAQS in the 2007 Guidance. Given the differences in the form of the 
standards between a 24-hour and an annual standard, EPA was less 
certain that such a presumption would be appropriate for all areas. For 
existing PM2.5 nonattainment areas, based on early technical 
analyses of PM2.5 composition and contributing source types, 
combined with an understanding of the existing PM2.5 
nonattainment areas, EPA noted its anticipation that the same 
boundaries established for implementing the 1997 annual 
PM2.5 NAAQS might also be appropriate for implementing the 
2006 24-hour PM2.5 NAAQS in areas where both standards are 
violated. EPA also observed that maintaining the same nonattainment 
area boundaries for both the 1997 annual standards and the 2006 24-hour 
standards could more easily facilitate overall air quality planning for 
attaining the suite of PM2.5 standards.
    Section 107(d)(1)(A)(i) of the CAA requires EPA to designate as 
nonattainment not only violating areas, but also nearby areas that 
contribute to those violations. As noted above, the statute does not, 
however, define key terms such are ``area,'' ``contributes,'' or 
``nearby.''
    With respect to the term ``contributes,'' EPA believes that this 
term does not mean ``cause.'' The term ``contributes'' indicates that 
those areas with emissions that add to the aggregate ambient pollution 
recorded by a given monitor might be appropriate for inclusion in a 
nonattainment area. To interpret the term contribute to mean ``cause'' 
would be to require a degree of certainty and precision that is 
inherently unreasonable for evaluating violations that result from the 
impact of emissions from many different sources of PM2.5 and 
PM2.5 precursors, and would simultaneously undermine the 
purpose of designations by excluding every area with emissions that 
added to the aggregate problem, yet did not individually ``cause'' the 
violation. EPA also has concluded that a bright line test or threshold 
for what would constitute contribution for purposes of designations is 
not appropriate for the 2006 24-hour PM2.5 NAAQS. Such an 
approach could result in over- or under-inclusive areas, compared to 
robust analysis of the facts and circumstances of each area. Similarly, 
EPA does not interpret the term ``contributes'' to mean ``significantly 
contributes,'' and does not believe that precise quantification of the 
contribution to violations in a nearby area is necessary or appropriate 
for designations. EPA generally agrees that areas with no sources of 
emissions, or areas that are otherwise demonstrated not to be 
contributing to violations, need not be included in a designated 
nonattainment area. However, EPA has concluded that the assessment of 
the ``causation'' and ``materiality'' of contribution to nearby 
violations is best accomplished through a more careful evaluation of 
the relevant information on an area-by-area basis.
    As to what areas should be considered ``nearby,'' EPA believes that 
this term must likewise be viewed in light of the specific pollutant at 
issue. In the case of the 2006 24-hour PM2.5 NAAQS, this 
entails consideration of the relatively long distances across which 
PM2.5 and PM2.5 precursors can be transported, 
but balanced with a key purpose of designations, which is to identify 
those nearby or local contributing areas that properly should be 
included within a designated nonattainment area to ensure the 
development of an appropriate SIP for the area. Thus, EPA's guidance 
also does not provide a bright line or threshold or specific geographic 
distance for what constitutes a ``nearby'' area. The determination of 
which areas are nearby, for purposes of designations, requires an 
evaluation of the facts and circumstances of each area. EPA considered 
the geography of each area, meteorological data, chemical speciation 
data, and other relevant information in light of the significant 
distances across which PM2.5 and PM2.5 precursors 
can be transported. EPA has used this process to identify those nearby 
areas with emissions that contribute to the violations and to 
distinguish these emissions from more distant or regional sources that 
are not appropriate for inclusion within the nonattainment area. In 
particular, EPA does not believe that the term ``nearby'' requires that 
the area be contiguous with the violating area or the remainder of the 
nonattainment area, if the facts support such a conclusion for a given 
area.
    As to the term ``area,'' EPA concluded that it also should be 
interpreted as appropriate to the specific NAAQS at issue. In drawing 
nonattainment areas boundaries, EPA started with county boundaries as 
the basic jurisdictional element, consistent with past designation 
practice. Although EPA determined that county boundaries are a useful 
starting point, relevant facts and circumstances could support making 
partial county boundary designations for violating or contributing 
counties in a given area.
    EPA began its technical analyses by first identifying violating 
monitors. In evaluating areas potentially contributing to a monitored 
violation, EPA initially examined those counties located in the 
surrounding metropolitan statistical area (i.e., the core-based 
statistical area (CBSA)) and those counties one to two adjacent rings 
beyond the metropolitan area. In its Notice on Standards for Defining 
Metropolitan and Micropolitan Areas (65 FR 82228, December 27, 2000), 
the Office of Management and Budget (OMB) notes that the general 
concept of a metropolitan statistical area is that of ``an area 
containing a recognized population nucleus and adjacent communities 
that have a high degree of integration with that nucleus.'' Further, 
the metropolitan statistical area serves as a ``statistical 
representation of the social and economic linkages between an urban 
core and outlying, integrated areas.'' Because of the inherent linkage 
between air pollution and pollution-producing human and economic 
activity, EPA believes that the CBSA, plus one to two adjacent rings 
beyond the metropolitan area, is an appropriate starting point for 
evaluation of contributing areas.\15\
---------------------------------------------------------------------------

    \15\ This consideration is important because EPA needs a 
reasonable method to distinguish between the ``local'' and the 
``non-local'' or ``regional'' components of ambient fine particles 
at a violating monitor. Section 107(d) directs EPA to include those 
``nearby'' areas that contribute, and therefore are logically 
appropriate for inclusion in the designated nonattainment area, 
whereas other sections of the CAA better address the regional 
element of a nonattainment problem, such as section 110(a)(2)(D) and 
section 126.
---------------------------------------------------------------------------

    EPA evaluated the types of information recommended in the 2007 
Guidance, as well as other relevant information that states or tribes 
provided or that became available, in determining appropriate 
nonattainment area boundaries. The nine factors EPA recommended in the 
2007 Guidance are: (1) Emissions data, (2) air quality data, (3) 
population density and degree of urbanization including commercial 
development in included versus excluded areas, (4) traffic and 
commuting patterns, (5) expected growth (including extent, pattern and 
rate of growth), (6) meteorology (weather/transport patterns), (7) 
geography/topography (e.g., mountain ranges or other air basin 
boundaries), (8) jurisdictional boundaries (e.g., counties, air 
districts, Reservations), and (9) level of existing controls on 
emission sources. This was neither a mandatory nor an exclusive list of 
types of relevant

[[Page 58695]]

information, and was intended by EPA only as guidance concerning the 
types of information that might be appropriate for consideration in a 
given area. These factors are by their nature general and open ended, 
and EPA intended them to facilitate analysis of each area on its 
specific facts. Some factors were more relevant or important in some 
areas than in others in establishing the boundaries of a given area.
    As part of the technical analysis, EPA also used an analytical tool 
to produce a metric referred to as the ``contributing emissions score'' 
(CES). The CES takes into consideration emissions data, meteorological 
data, and air quality monitoring information to provide a relative 
ranking of the potential contribution from counties near a specific 
county with a violating monitor. EPA did not use this metric as the 
exclusive way of considering data for these three factors, nor as the 
single deciding factor for determining designations. The CES was merely 
an additional method for evaluating the potential contribution of 
nearby counties.\16\
---------------------------------------------------------------------------

    \16\ The CES only provides relative contribution within the area 
under evaluation and does not provide a reliable means for 
comparison between counties in different areas. A more detailed 
description of the CES can be found at http://www.epa.gov/ttn/naaqs/
pm/pm25_2006_techinfo.html#C. and in the technical support 
document (TSD) [Docket ID NO. EPA-HQ-OAR-2007-0562].
---------------------------------------------------------------------------

    To evaluate an area, EPA also used additional data and analytical 
tools as appropriate, including speciated PM2.5 data, area 
maps, and tools for assessing wind patterns. For purposes of 
determining appropriate nonattainment area boundaries, EPA examined 
data from PM2.5 speciation monitors, where available, in 
addition to the ambient PM2.5 concentration data from FRM 
monitors. The speciated PM2.5 data indicated the relative 
proportions of specific types of particles at monitors (e.g., 
SO2, NO3, carbonaceous, or crustal particles). 
These data provided insights as to likely sources of emissions 
contributing to the ambient PM2.5 concentrations at the 
violating monitor on days with high PM2.5 levels, thus 
allowing EPA to better evaluate which, if any, of the nearby areas were 
contributing to the ambient PM2.5 concentrations at the 
violating monitor.
    EPA used maps of each area that depicted key geographic 
information. These maps portrayed relevant information such as the 
locations of FRM monitors and their design values, jurisdictional 
boundaries, topographic features, major transportation arteries, major 
emission sources, and existing nonattainment boundaries for other 
NAAQS. The maps assisted in the evaluation of basic information such as 
the directions and distances between monitors and sources and the 
locations of jurisdictional boundaries.
    EPA also assessed wind pattern data through the development and use 
of ``pollution roses'' that depict monitoring data and meteorological 
data for monitors in each area. In some cases, where a more detailed 
assessment of air movement was thought to provide additional relevant 
information, EPA also used wind trajectory analyses. These tools for 
assessing wind movement and pollutant concentrations provided further 
information on likely emission sources contributing to PM2.5 
levels at monitors on days at or near the level of the 24-hour 
PM2.5 NAAQS.
    In evaluating emissions in areas under consideration for their 
contribution, EPA generally relied on the best county-level emissions 
inventory information available. In some areas, EPA reviewed whether 
significant pollution controls that would be installed in the near-term 
and with certainty at a specific source or sources, could be relevant 
to evaluating whether that area is contributing to violations in an 
adjacent area. EPA examined this type of information when states 
provided the requisite data and requested its evaluation as part of the 
process. EPA considered such information on a case-by-case basis, with 
attention to whether the controls in question would dramatically reduce 
the emissions of PM2.5 and all PM2.5 precursors, 
the timing of such controls, and the federal enforceability of such 
controls. EPA considered only controls that would be in place no later 
than December 2008 (i.e., controls resulting in emissions reductions 
during the last year of the period for which air quality monitoring 
data was relevant).
    By contrast, EPA did not rely on planned or potential emissions 
reduction strategies through measures such as the Clean Air Interstate 
Rule, in making nonattainment designations, even if those strategies 
might help an area attain the standards in the future. The Agency 
recognizes that air quality modeling of future emissions reductions 
(e.g., from state and/or national programs) may indicate that some 
areas with a violating monitor based upon 2006-2008 data may come into 
attainment in the future. However, the present tense formulation of 
section 107(d) indicates that EPA should make nonattainment 
designations based on current data.\17\ Future potential reductions, 
especially those that are at this time speculative or uncertain, are 
not appropriate for consideration in the designations context. Such 
programs might, however, be an appropriate consideration in the 
development of SIPs for designated nonattainment areas, if they 
otherwise meet statutory and regulatory requirements.
---------------------------------------------------------------------------

    \17\ While EPA cannot consider projected future attainment in 
determining current designations, nonattainment areas that are 
meeting the NAAQS but are not yet redesignated to attainment can use 
EPA's Clean Data Policy to streamline the required planning process. 
See ``Clean Data Policy for the Fine Particle National Ambient Air 
Quality Standards'' memorandum to Air Division Directors, Regions I-
X from Stephen Page, Director, Office of Air Quality Planning and 
Standards, December 14, 2004.
---------------------------------------------------------------------------

    In order to identify the appropriate boundaries for nonattainment 
areas, EPA considered the county boundary as the basic jurisdictional 
element for determining area boundaries, consistent with past 
designation practice. The Agency believes that such county boundaries 
are generally an appropriate boundary because they are easily 
recognized jurisdictional boundaries with indisputable legal 
descriptions. County boundaries are often the boundaries for the legal 
jurisdiction of local governments or air quality planning organizations 
that are responsible for air quality management.
    In most cases, if a PM2.5 monitor was violating the 
NAAQS, EPA designated the entire county in which that monitor is 
located as nonattainment. EPA also often included whole nearby counties 
that it determined to be contributing to PM2.5 levels at the 
violating monitor. In some cases, however, EPA determined that only 
part of a county (e.g., the part of the county that contained the 
sources of contributing emissions) was contributing to the violation at 
the monitor. In those instances, EPA designated only that portion of 
the county nonattainment and, to the extent possible, relied on 
recognized governmental boundaries for smaller geographic areas that 
encompassed the relevant emission sources (e.g., townships).
    For example, in some cases, EPA determined that the emissions from 
a large individual source such as a power plant were contributing to 
violations in a nearby area. If EPA's assessment identified little or 
no other emissions or emitting activity elsewhere in the county (based 
on assessment of factors such as emissions, population, and commuting), 
EPA concluded that it was appropriate to designate as nonattainment 
only the portion of the county where the large individual

[[Page 58696]]

source is located, even if that portion is not contiguous with the 
remainder of the nonattainment area. The Agency adopted this approach 
for areas where EPA determined it to be inappropriate to include 
portions of a county merely because those portions were located 
between, and contiguous with, the large stationary source and the 
remainder of the designated nonattainment area. In most cases, EPA 
selected boundaries for these noncontiguous portions of nonattainment 
areas by relying on legally recognized governmental boundaries (e.g., 
townships, tax districts, or census blocks) in which the source is 
located.
    EPA also determined partial county boundaries to be appropriate for 
some areas where a topographic feature, such as a mountain range, helps 
to define the airshed in which the violation of PM2.5 
standards occurs, or separates contributing from non-contributing 
areas. In some areas, EPA determined that only a portion of a county 
was determined to be contributing, due to such a topographic barrier. 
In a few cases, especially in the West, an area with a violating 
monitor was topographically isolated from other portions of a much 
larger county or borough with few or no sources of emissions. EPA 
considered a partial county to be appropriate for such areas and 
selected boundaries based on topography, using recognized governmental 
boundaries (e.g., township ranges), where possible.
    Where topography was not an isolating feature, EPA considered the 
geographic location of the sources of PM2.5 and 
PM2.5 precursors in the area, and other relevant 
information, such as chemical speciation data and meteorological data, 
in determining if a partial county boundary was technically justified 
and appropriate. EPA also considered a partial county boundary for 
violating counties in situations where a unique situation is shown to 
exist, in which the sources encompassed by a partial county boundary 
could account for nearly all of the total fine particle mass from local 
sources on days with a monitored exceedance. In such areas, given 
compelling evidence, EPA considered designations of partial violating 
counties to be appropriate. These areas are typically in the 
mountainous portions of the West, where emissions activity in a 
relatively small and isolated geographic area is surrounded by large 
areas that are largely unpopulated and otherwise lack sources that 
could contribute to the monitored violations. EPA notes that the 24-
hour averaging period of the 2006 24-hour PM2.5 NAAQS was an 
important consideration in these areas. EPA selected the boundaries for 
these areas by relying on legally recognized governmental boundaries 
(e.g., townships) in which the contributing sources are located.
    EPA analyzed the information provided by each state or tribe in its 
recommendation letter, subsequently submitted information, and any 
other pertinent information available to EPA, in order to determine 
whether a county or part of a county should be designated 
nonattainment. EPA evaluated each state's or tribe's designation 
recommendation in light of the recommended nine factors, and any other 
relevant information, including, for example, the CES, PM2.5 
speciation data, and wind pattern data, bringing to bear our best 
technical and policy judgment. If, as a result of the evaluation, EPA 
concluded that a county or part of a county contributes to the 
violation in a nearby area with a violating monitor, EPA included the 
county or part of the county in the nonattainment area.

VIII. What Areas is EPA Designating Nonattainment for the 2006 24-Hour 
PM2.5 NAAQS?

    Following the process described above, EPA is designating the 31 
areas in Table 1 below, comprised of one or more entire counties or 
partial counties, as nonattainment areas for the 2006 24-hour 
PM2.5 NAAQS.

    EPA's specific analysis of these areas, including the determination 
of the appropriate nonattainment area boundaries for each of these 
areas, is described in detail in the TSD, with additional information 
provided in the Supplemental TSD. Both documents are located in the 
docket for this action. In addition, the letters containing the initial 
state or tribal recommendations for each of these areas, any EPA 
modification to those recommendations, and any additional information 
provided by the state or tribe in response to EPA modifications, is 
also located in the docket. The specific area or areas within the 
boundaries for each of these designated nonattainment areas is 
described in the amendments to 40 CFR part 81 below, and is graphically 
portrayed in the maps located in the docket for this action.

IX. How Has EPA Used 2008 Air Quality Data?

    In December 2008, EPA identified 58 areas as violating the 2006 24-
hour PM2.5 NAAQS based on air quality monitoring data for 
the 2005-2007 time period. In the 2007 Guidance, EPA recommended that 
designation decisions be based on the most recent three years of data 
available. In the December 2008 notice, which was not published in the 
Federal Register in order to allow additional Agency review, and in 
communications with states and tribes, EPA had indicated that it would 
consider state requests to include consideration of 2008 air quality 
monitoring data for specific areas prior to the effective date of 
designations under certain circumstances. Due to the delay in the 
designations, however, EPA now has received and reviewed quality 
assured, state-certified 2008 air quality monitoring data for all 
areas.
    EPA continues to believe that inclusion of the most recent air 
quality monitoring data available is appropriate for designation 
decisions. Thus, EPA is designating as attainment those areas for which 
complete, quality assured, certified air quality monitoring data for 
the 2006-2008 time period show attainment of the 2006 24-hour 
PM2.5 NAAQS throughout the area. EPA is not reconsidering 
the boundaries for the

[[Page 58697]]

areas identified as nonattainment in December 2008 and for which 
consideration of 2006-2008 air quality data does not change the overall 
status of the area. The boundaries EPA identified in December 2008 were 
based upon thorough consideration of the relevant information by EPA. 
EPA believes that it is appropriate to rely on the 2008 air quality 
monitoring data and the extensive information and analyses used in the 
decision making process that spanned the period from approximately June 
2007-December 2008. EPA does not believe that the introduction of 
additional non-air quality information into the process at this time 
would yield different designation outcomes; and, in fact doing so would 
cause unjustified delay in issuing these final designations based upon 
2006-2008 air quality monitoring data.
    Consideration of 2006-2008 air quality monitoring data reduced the 
number of areas violating the 2006 24-hour PM2.5 NAAQS from 
58 to 31. Table 2 provides a list of the 26 areas that changed from 
nonattainment to attainment and their design values for 2005-2007 and 
2006-2008. For one area no longer violating the 2006 24-hour 
PM2.5 NAAQS based on 2006-2008 data, York County, PA, EPA 
concluded that it nevertheless contributes to violations in another 
nearby violating area, Harrisburg-Lebanon-Carlisle, PA, and thus EPA 
has included York County, PA in that nonattainment area. Five of the 
areas that changed from a designation status of nonattainment to 
attainment had one or more monitors with incomplete data for 2006-2008. 
However, data from the highest design value monitor for the area in 
2005-2007, as well as other monitors, are complete and show attainment 
of the 24-hour PM2.5 NAAQS for 2006-2008. As explained in 
detail in the Supplemental TSD, based on the relative values of the 
various monitors, EPA believes it is reasonable to expect that, if the 
incomplete site had complete 2006-2008 data, it would have a design 
value equal to or lower than the other sites with complete data that 
are attaining the NAAQS based on the 2006-2008 data. The additional 
technical information to support the change in status for all of the 
areas, including the supporting evaluation for the inclusion of York 
County in the Harrisburg-Lebanon-Carlisle, PA nonattainment area and 
for the five areas noted above, is included in the Supplemental TSD, 
which is located in the docket for this action.

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

    EPA's evaluation of 2006-2008 air quality monitoring data also 
indicated that monitors in three areas which had not violated the 2006 
24-hour PM2.5 NAAQS based on 2005-2007 data now violate 
those standards based on 2006-2008 data. These monitors are located in 
Pinal County, AZ (2006-2008 24-hour design value of 48); Plumas County, 
CA (2006-2008 24-hour design value of 49); and, Shasta County, CA 
(2006-2008 24-hour design value of 48). In this notice, EPA is not 
finalizing initial designations for these newly violating areas. 
Because these areas are newly violating the 2006 24-hour 
PM2.5 NAAQS, EPA and the states and tribes in these areas 
need further information in order to determine the appropriate 
nonattainment area boundaries for these areas, in accordance with the 
process that EPA has used for other nonattainment area designations, as 
provided by section 107(d).
    Because EPA has information indicating that there is a violation in 
each of these areas, a designation of ``unclassifiable'' is not 
appropriate under section 107(d)(1)(A)(iii). Notwithstanding data 
indicating violations of the 24-hour PM2.5 NAAQS, EPA has 
insufficient information to determine the necessary boundaries for 
these areas. Accordingly, EPA will use the additional time available to 
it under section 107(d)(1)(B) to assess these

[[Page 58698]]

areas, complete evaluation of any pending exceptional event claims, and 
promulgate initial designations for these areas. Consistent with the 
approach used to assess other potential nonattainment areas, EPA 
intends to evaluate relevant technical data for the ring of counties 
immediately surrounding the violating county to determine whether any 
of these nearby counties contribute to the violation. EPA is deferring 
the designations for these counties for the 2006 24-hour 
PM2.5 NAAQS so that EPA can collect additional information 
sufficient to assess these areas before promulgating these 
designations. We recognize that these are large geographical areas. 
Including all counties surrounding the county with the violating 
monitor is only a starting point for the evaluation; it should not be 
assumed that the final designated nonattainment area will include all 
of these counties. Table 3 provides a list of the counties with 
violating monitors and the additional nearby areas that EPA believes 
should be evaluated for potential contribution to those violations.
    EPA will work with the relevant states and tribes to finalize the 
designations for these counties over the next several months. EPA will 
send letters notifying the states and tribes in question that EPA 
believes a modification is now necessary to the initial recommendations 
they made for these areas. Each state and tribe will thereafter have an 
opportunity to respond to EPA's proposed designations and boundaries. 
Pursuant to section 107(d), EPA cannot promulgate the designation for 
these areas less than 120 days from the date of the EPA modification 
letter. EPA will promulgate the designations for these areas by a 
separate final rule.

Pima County, AZ                       Yuba County, CA (part)                Trinity County, CA
Yavapai County, AZ
Yuma County, AZ
----------------------------------------------------------------------------------------------------------------

    The quality assured, certified air quality monitoring data for 
2006-2008 also indicate that two counties that EPA designated in 2005 
as attainment for the 1997 annual PM2.5 NAAQS now have 
monitors which are potentially violating that NAAQS.\18\ These counties 
are Pinal County, AZ (2006-2008 annual average design value of 21.6) 
and Harris County, TX (2006-2008 annual average design value of 15.2). 
Consequently, EPA intends to initiate the redesignation process under 
section 107(d)(3) for these areas for the 1997 annual PM2.5 
NAAQS. EPA will work with the relevant states and tribes to evaluate 
the air quality data and other technical information in order to 
determine whether these areas should be redesignated to nonattainment, 
and if so, the appropriate boundaries for those nonattainment areas. 
EPA will promulgate these redesignations by a later final rule.
---------------------------------------------------------------------------

    \18\ In the 2006 revision of the PM NAAQS, the level of the 
annual standard remained unchanged at 15 [mu]g/m3. Petitioners 
challenged this decision. On February 24, 2009, the U.S. Court of 
Appeals for the DC Circuit remanded the annual PM2.5 
standard to the Agency for reconsideration on the basis that EPA did 
not adequately explain why retaining this level would be sufficient 
to protect public health. To address those areas now violating the 
1997 annual PM2.5 NAAQS, EPA intends to initiate 
redesignations, as appropriate.
---------------------------------------------------------------------------

X. How Do Designations Affect Indian Country?

    All full counties, partial counties or Air Quality Control Regions 
listed in the Part 81 table at the end of this document are designated 
as indicated, and include Indian Country geographically located within 
such areas, except as otherwise indicated in the table.
    In general, and consistent with relevant air quality information, 
EPA intends to include Indian Country encompassed within the 
nonattainment area, in order to protect public health and welfare. In 
most cases, relevant air quality information will indicate that areas 
of Indian Country located within a nonattainment area should have the 
same designation as the surrounding area. See discussion above about 
tribal responsibility.
    EPA does not recognize state recommendations for area designations 
as applying to Indian country. However, the conditions that support a 
state's designation recommendation, such as air quality data at the 
location of the sources, may indicate the likelihood that similar 
conditions exist in adjacent Indian Country. States generally have 
neither the responsibility nor the authority for planning and 
regulatory activities under the CAA in Indian country.

XI. Where Can I Find Information Forming the Basis for This Rule and 
Exchanges Between EPA, States, and Tribes Related to This Rule?

    Information providing the basis for this action and related 
decisions are provided in the TSD, response to comments documents, and 
other information in the docket. The TSD, applicable EPA guidance 
memoranda, copies of correspondence regarding this process between EPA 
and the states, tribes, and other parties, and EPA's responses to 
comments, are available for review at the EPA Docket Center listed 
above in the addresses section of this document and on our designation 
Web site at http://www.epa.gov/pmdesignations/2006standards/index.htm. 
Other related state specific information is available at the EPA 
Regional Offices.

XII. Statutory and Executive Order Reviews

    Upon promulgation of a new or revised NAAQS, the CAA requires EPA 
to designate areas as attaining or not attaining the NAAQS. The CAA 
then specifies requirements for areas based on whether such areas are 
attaining or not attaining the NAAQS. In this final rule, EPA assigns 
designations to areas as required.

[[Page 58699]]

A. Executive Order 12866: Regulatory Planning and Review

    This action is not a ``significant regulatory action'' under the 
terms of Executive Order (EO) 12866 (58 FR 51735, October 4, 1993) and 
is therefore not subject to review under the EO.

B. Paperwork Reduction Act

    This action does not impose an information collection burden under 
the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. 
Burden is defined at 5 CFR 1320.3(b). This rule responds to the 
requirement to promulgate air quality designations after promulgation 
of a NAAQS. This requirement is prescribed in the CAA section 107 of 
title 1. The present final rule does not establish any new information 
collection apart from that required by law.

C. Regulatory Flexibility Act

    This final rule is not subject to the Regulatory Flexibility Act 
(RFA), which generally requires an agency to prepare a regulatory 
flexibility analysis for any rule that will have a significant economic 
impact on a substantial number of small entities. The RFA applies only 
to rules subject to notice and comment rulemaking requirements under 
the Administrative Procedure Act (APA) or any other statute. This rule 
is not subject to notice and comment requirements under the APA or any 
other statute because the rule is not subject to the APA and is subject 
to CAA section 107(d)(2)(B), which does not require that the Agency 
issue a notice of proposed rulemaking before issuing this rule.

D. Unfunded Mandates Reform Act

    This action contains no federal mandate under the provisions of 
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), 2 U.S.C. 
1531-1538 for state, local, or tribal governments or the private 
sector. The action imposes no enforceable duty on any state, local or 
tribal governments or the private sector. Therefore, this action is not 
subject to the requirements of sections 202 and 205 of the UMRA.
    This action is also not subject to the requirements of section 203 
of UMRA because it contains no regulatory requirements that might 
significantly or uniquely affect small governments. It does not create 
any additional requirements beyond those of the PM2.5 NAAQS 
(40 CFR 50.13), therefore, no UMRA analysis is needed. This rule 
establishes the application of the PM2.5 standard and the 
designation for each area of the country for the PM2.5 
NAAQS. The CAA requires states to develop plans, including control 
measures, based on their designations and classifications.
    One mandate that may apply as a consequence of this action to all 
designated nonattainment areas is the requirement under CAA section 
176(c) and associated regulations to demonstrate conformity of federal 
actions to SIPs. These rules apply to federal agencies and Metropolitan 
Planning Organizations making conformity determinations. The EPA 
concludes that such conformity determinations will not cost $100 
million or more in the aggregate.
    The EPA believes that any new controls imposed as a result of this 
action will not cost in the aggregate $100 million or more annually. 
Thus, this federal action will not impose mandates that will require 
expenditures of $100 million or more in the aggregate in any one year.
    Nonetheless, EPA carried out consultation with government entities 
affected by this rule, including states, tribal governments, and local 
air pollution control agencies.

E. Executive Order 13132: Federalism

    Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August 
10, 1999), requires EPA to develop an accountable process to ensure 
meaningful and timely input by state and local officials in the 
development of regulatory policies that have federalism implications. 
``Policies that have federalism implications'' is defined in the 
Executive Order to include regulations that have ``substantial direct 
effects on the states, or the relationship between the national 
government and the states, or on the distribution of power and 
responsibilities among the various levels of government.''
    This final rule does not have federalism implications. It will not 
have substantial direct effects on the states, on the relationship 
between the national government and the states, or on the distribution 
of power and responsibilities among the various levels of government, 
as specified in Executive Order 13132. The CAA establishes the process 
whereby states take the lead in developing plans to meet the NAAQS. 
This rule will not modify the relationship of the states and EPA for 
purposes of developing programs to implement the NAAQS. Thus, Executive 
Order 13132 does not apply to this rule.

F. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    Executive Order 13175, entitled ``Consultation and Coordination 
with Indian Tribal Governments'' (65 FR 67249, November 2, 2000), 
requires EPA to develop an accountable process to ensure ``meaningful 
and timely input by tribal officials in the development of regulatory 
policies that have Tribal implications.'' This action does not have 
tribal implications, as specified in Executive Order 13175 (65 FR 
67249, November 9, 2000). This rule concerns the designation and 
classification of areas as attainment and nonattainment for the 
PM2.5 national ambient air quality standards. The CAA 
provides for states and eligible tribes to develop plans to regulate 
emissions of air pollutants within their areas based on their 
designations. The TAR provides tribes the opportunity to apply for 
eligibility to develop and implement CAA programs such as programs to 
attain and maintain the PM2.5 NAAQS, but it leaves to the 
discretion of the tribe the decision of whether to apply to develop 
these programs and which programs, or appropriate elements of a 
program, the tribe will seek to adopt. This rule does not have a 
substantial direct effect on one or more Indian tribes. It does not 
create any additional requirements beyond those of the PM2.5 
NAAQS (40 CFR 50.13). This rule establishes the application of the 
PM2.5 standard and the designation and classification for 
each area of the country for the PM2.5 NAAQS. Additionally, 
no tribe has implemented a CAA program to attain the PM2.5 
NAAQS at this time. Furthermore, this rule does not affect the 
relationship or distribution of power and responsibilities between the 
federal government and Indian tribes. The CAA and the TAR establish the 
relationship of the federal government and tribes in developing plans 
to attain the NAAQS, and this rule does nothing to modify that 
relationship. Because this rule does not have tribal implications, 
Executive Order 13175 does not apply.
    Although Executive Order 13175 does not apply to this rule, EPA 
communicated with tribal leaders and environmental staff regarding the 
designations process. EPA also sent individualized letters to all 
federally recognized tribes to explain the designation process for the 
2006 24-hour PM2.5 NAAQS, to provide the EPA designations 
guidance, and to offer consultation with EPA. EPA provided further 
information to tribes through presentations at the National Tribal

[[Page 58700]]

Forum and through participation in National Tribal Air Association 
conference calls. EPA also sent individualized letters to all federally 
recognized tribes about EPA's intended area designations for the 24-
hour PM2.5 standards and offered tribal leaders the 
opportunity for consultation. These communications provided 
opportunities for tribes to voice concerns to EPA about the general 
designations process for the 24-hour PM2.5 NAAQS, as well as 
concerns specific to a tribe, and informed EPA about key tribal 
concerns regarding designations as the rule was under development.

G. Executive Order 13045: Protection of Children From Environmental 
Health and Safety Risks

    The action is not subject to Executive Order 13045 (62 FR 19885, 
April 23, 1997) because it is not economically significant as defined 
in Executive Order 12866, and because EPA does not have reason to 
believe that the environmental health risks or safety risks addressed 
by this rule present a disproportionate risk or safety risk to 
children. Nonetheless, we have evaluated the environmental health or 
safety effects of the PM2.5 NAAQS on children. The results 
of this risk assessment are contained in the NAAQS for the 2006 24-hour 
PM2.5, Final Rule (October 17, 2006, 71 FR 61144).

H. Executive Order 13211: Actions That Significantly Affect Energy 
Supply, Distribution, or Use

    This action is not subject to Executive Order 13211 (66 FR 28355 
(May 22, 2001)), because it is not a significant regulatory action 
under Executive Order 12866.

I. National Technology Transfer and Advancement Act (NTTAA)

    Section 12(d) of the NTTAA of 1995, Public Law No. 104-113, section 
12(d) (15 U.S.C. 272 note), directs EPA to use voluntary consensus 
standards (VCS) in its regulatory activities unless to do so would be 
inconsistent with applicable law or otherwise impracticable. Voluntary 
consensus standards are technical standards (e.g., materials 
specifications, test methods, sampling procedures, and business 
practices) that are developed or adopted by VCS bodies. The NTTAA 
directs EPA to provide Congress, through OMB, explanations when the 
Agency decides not to use available and applicable VCS.
    This action does not involve technical standards. Therefore, EPA 
did not consider the use of any VCS.

J. Executive Order 12898: Federal Actions To Address Environmental 
Justice in Minority Populations and Low-Income Populations

    Executive Order 12898 (59 FR 7629 (Feb. 16, 1994)) establishes 
federal executive policy on environmental justice. Its main provision 
directs federal agencies, to the greatest extent practicable and 
permitted by law, to make environmental justice part of their mission 
by identifying and addressing, as appropriate, disproportionately high 
and adverse human health or environmental effects of their programs, 
policies, and activities on minority populations and low-income 
populations in the U.S.
    The EPA has determined that this final rule will not have 
disproportionately high and adverse human health or environmental 
effects on minority or low-income populations because this rule does 
not affect the level of protection provided to human health or the 
environment.

K. Congressional Review Act

    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 
U.S. The EPA will submit a report containing this rule and other 
required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the U.S. 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). This rule will be effective December 14, 2009.

L. Judicial Review

    Section 307(b)(1) of the CAA indicates which Federal Courts of 
Appeal have venue for petitions of review of final actions by EPA. This 
section provides, in part, that petitions for review must be filed in 
the Court of Appeals for the District of Columbia Circuit: (i) When the 
agency action consists of ``nationally applicable regulations 
promulgated, or final actions taken, by the Administrator,'' or (ii) 
when such action is locally or regionally applicable, if ``such action 
is based on a determination of nationwide scope or effect and if in 
taking such action the Administrator finds and publishes that such 
action is based on such a determination.''
    This rule designating areas for the 2006 24-hour PM2.5 
NAAQS is ``nationally applicable'' within the meaning of section 
307(b)(1). This rule establishes designations for areas across the U.S. 
for the 2006 24-hour PM2.5 NAAQS. At the core of this 
rulemaking is EPA's interpretation of the definition of nonattainment 
under section 107(d)(1) of the CAA. In determining which areas should 
be designated nonattainment (or conversely, should be designated 
attainment or unclassifiable), EPA used an analytical approach that it 
applied consistently across the U.S..
    For the same reasons, the Administrator also is determining that 
the final designations are of nationwide scope and effect for the 
purposes of section 307(b)(1). This is particularly appropriate 
because, in the report on the 1977 Amendments that revised section 
307(b)(1) of the CAA, Congress noted that the Administrator's 
determination that an action is of ``nationwide scope or effect'' would 
be appropriate for any action that has a scope or effect beyond a 
single judicial circuit. H.R. Rep. No. 95-294 at 323, 324, reprinted in 
1977 U.S.C.C.A.N. 1402-03. Here, the scope and effect of this 
rulemaking extends to numerous judicial circuits since the designations 
apply to all areas of the country. In these circumstances, section 
307(b)(1) and its legislative history calls for the Administrator to 
find the rule to be of ``nationwide scope or effect'' and for venue to 
be in the DC Circuit.
    Thus, any petitions for review of final designations must be filed 
in the Court of Appeals for the District of Columbia Circuit within 60 
days from the date final action is published in the Federal Register.

2. Section 81.300 is amended by revising paragraph (a) to read as 
follows:

Sec.  81.300  Scope.

* * * * *
    (a) Attainment status designations as approved or designated by the 
Environmental Protection Agency (EPA) pursuant to section 107 of the 
CAA are listed in this subpart. Area designations are subject to 
revision whenever sufficient data become available to warrant a 
redesignation. Both the state and EPA can initiate changes to these 
designations, but any state redesignation request must be submitted to 
EPA for concurrence. The EPA has replaced the national ambient air 
quality standards for particulate matter measured as total suspended 
particulate with standards measured as particulate matter with an 
aerodynamic diameter less than or equal to a nominal 10 micrometers 
(PM-10). Accordingly, area designations for PM-10 are included in the 
lists in subpart C of this part. However, the TSP area designations 
will also remain in effect until the Administrator determines that the 
designations are no longer necessary for implementing the maximum 
allowable increases in concentrations of particulate matter pursuant to 
section 163(b) of the CAA, as explained in paragraph (b) of this 
section. The EPA has also added national ambient air quality standards 
for fine particulate matter measured as particulate matter with an 
aerodynamic diameter less than or equal to a nominal 2.5 micrometers 
(PM2.5). Accordingly, area designations for PM2.5 
are included in the lists in subpart C of this part.

    Begin in the bottom left
     corner (southwest) of the
     nonattainment area boundary,
     southwest corner of the PLSS-
     Boise Meridian, Township 16
     South, Range 37 East, Section
     25. The boundary then
     proceeds north to the
     northwest corner of Township
     15 South, Range 37 East,
     Section 25; then the boundary
     proceeds east to the
     southeast corner of Township
     15 South, Range 38 East,
     Section 19; then north to the
     Franklin County boundary at
     the northwest corner of
     Township 13 South, Range 38
     East, Section 20. From this
     point the boundary proceeds
     east 3.5 sections along the
     northern border of the county
     boundary where it then turns
     south 2 sections, and then
     proceeds east 5 more
     sections, and then north 2
     sections more. At this point,
     the boundary leaves the
     county boundary and proceeds
     east at the southeast corner
     of Township 13 South, Range
     39 East, Section 14; then the
     boundary heads north 2
     sections to northwest corner
     of Township 13 South, Range
     39 east, Section 12; then the
     boundary proceeds east 2
     sections to the northeast
     corner of Township 13 South,
     Range 40 East, Section 7. The
     boundary then proceeds south
     2 sections to the northwest
     corner of Township 13 South,
     Range 40 East, Section 20;
     the boundary then proceeds
     east 6 sections to the
     northeast corner of Township
     13 South, Range 41 East,
     Section 19. The boundary then
     proceeds south 20 sections to
     the southeast corner of
     Township 16 South, Range 41
     East, Section 30. Finally,
     the boundary is completed as
     it proceeds west 20 sections
     along the southern Idaho
     state boundary to the
     southwest corner of the
     Township 16 South, Range 37
     East, Section 25.
