II. Background
A. PM10 Standard
The NAAQS are levels for certain ambient air pollutants set by EPA
to protect public health and welfare. PM10, or particulate
matter with an aerodynamic diameter less than or equal to a nominal 10
micrometers, is among the ambient air pollutants for which EPA has
established health-based standards. On July 1, 1987 (52 FR 24634), EPA
promulgated two primary standards for PM10: A 24-hour
standard of 150 micrograms per cubic meter ([mu]g/m\3\) and an annual
PM10 standard of 50 [mu]g/m\3\. EPA also promulgated
secondary PM10 standards that were identical to the primary
standards.
Effective December 18, 2006, EPA revoked the annual PM10
standard but retained the 24-hour PM10 standard.\1\ 71 FR
61144 (October 17, 2006). The 24-hour PM10 standard is
attained when the expected number of days per calendar year with a 24-
hour concentration above 154 [mu]g/m\3\, as determined in accordance
with 40 CFR part 50, appendix K, is equal to or less than one.\2\ 40
CFR 50.6 and 40 CFR part 50, appendix K.
---------------------------------------------------------------------------
\1\ Because the annual PM10 standard was revoked
effective December 18, 2006, see 71 FR 61144 (October 17, 2006),
this document discusses only attainment of the 24-hour
PM10 standard. Columbia Falls and Libby PM10
nonattainment areas were in attainment of the revoked annual
PM10 standard.
\2\ An exceedance is defined as a daily value that is above the
level of the 24-hour standard (150 [mu]g/m\3\) after rounding to the
nearest 10 [mu]g/m\3\ (i.e. values ending in 5 or greater are to be
rounded up). Thus, a recorded value of 154 [mu]g/m\3\ would not be
an exceedance since it would be rounded to 150 [mu]g/m\3\ whereas a
recorded value of 155 [mu]g/m\3\ would be an exceedance since it
would be rounded to 160 [mu]g/m\3\. See 40 CFR part 50, appendix K,
section 1.0.
---------------------------------------------------------------------------
The EPA also promulgated policies and regulations by which it will
implement the PM10 NAAQS (52 FR 24672). In accordance with
these policies, EPA has categorized areas of the Nation into three
groups based on the likelihood that the existing SIP must be revised to
protect the PM10 NAAQS. Areas with a strong likelihood of
violating the PM10 NAAQS and requiring substantial SIP
revisions were placed in Group I; areas where attainment of the
PM10 NAAQS is uncertain and the SIP may require only slight
adjustment were placed in Group II; and areas with a strong likelihood
of attaining the PM10 NAAQS, and therefore probably having
an adequate control strategy, were placed in Group III.\3\ By this
notice, EPA is identifying the Group I and Group II areas in Montana
that reached attainment.
---------------------------------------------------------------------------
\3\ The EPA used a three-step process to categorize areas into
Groups I, II, and III. First, where only ambient TSP data or limited
amounts of PM10 data were available, EPA in cooperation
with State agencies used those data and the probability guideline to
classify areas preliminarily as Group I, II, or III. The EPA
presumed that, at a minimum, the (1) areas with a probability of not
attaining the PM10 standard of at least 95 percent fit
into Group I; (2) areas with a probability of between 20 and 95
percent fit into Group II; and (3) areas with a probability of less
than 20 percent fit into Group III. 52 FR 29383, 29384 (August 7,
1987).
---------------------------------------------------------------------------
B. Columbia Falls PM10 Nonattainment Area
On August 7, 1987 (52 FR 29383), EPA identified a number of areas
across the country as PM10 ``Group II'' areas of concern,
that is, areas between 20% and 95% likelihood of violating the
PM10 NAAQS. The Columbia Falls PM10 nonattainment
area was identified as a Group II area of concern.
Areas meeting the requirements of section 107(d)(4)(B) were
designated nonattainment for PM10 by operation of law and
classified ``moderate'' upon enactment of the 1990 Clean Air Act
Amendments. 42 U.S.C. 7407(d)(4)(B). These areas included all former
Group II PM10 planning areas identified on August 7, 1987
(52 FR 29383), and other areas violating the NAAQS for PM10
prior to January 1, 1989. On October 31, 1990 (55 FR 45799), EPA
further clarified the descriptions of Group I and Group II areas of
concern listed in the August 7, 1987 (52 FR 29383) notice. A Federal
Register notice announcing the areas designated nonattainment for
PM10 upon enactment of the 1990 Clean Air Act Amendments,
known as ``initial'' PM10 nonattainment areas, was published
on March 15, 1991 (56 FR 11101). The Columbia Falls PM10
nonattainment area was one of these initial moderate PM10
nonattainment areas.
i. Attainment Date for the Columbia Falls PM10 Nonattainment
Area
All initial moderate PM10 nonattainment areas had the
same applicable attainment date of December 31, 1994. States containing
initial moderate PM10 nonattainment areas were required to
develop and submit to EPA by November 15, 1991, a SIP revision
providing for implementation of reasonably available control measures
(RACM), including reasonably available control technology (RACT), and a
demonstration of whether attainment of
[[Page 5282]]
the PM10 NAAQS by the December 31, 1994 attainment date was
practicable. See section 189(a).
ii. PM10 Planning in the Columbia Falls PM10
Nonattainment Area
After the Columbia Falls PM10 nonattainment area was
designated nonattainment for PM10, the Montana Board of
Health and Environmental Sciences (MBHES) began in the early 1990s to
prepare the technical elements needed to bring the area into attainment
and meet the planning requirements of Title I of the CAA. Based on
these technical elements, MBHES developed and implemented control
measures on PM10 sources in the Columbia Falls
PM10 nonattainment area. The Columbia Falls PM10
SIP was originally adopted by the MBHES on January 24, 1992, and
submitted to EPA on May 6, 1992. Deficiencies were identified by EPA
and the final technical corrections were submitted to EPA on June 15,
1993. EPA approved the Columbia Falls PM10 SIP on April 14,
1994, with technical corrections dated June 15, 1993 (59 FR 17700). The
State failed to submit the contingency measures by the November 15,
1993, due date. On January 19, 1994, EPA made a finding that the State
failed to submit the contingency measures. In response to this finding
the Governor of Montana submitted revisions to the SIP for Columbia
Falls dated August 26, 1994, to address the contingency measures and
EPA approved the revisions on March 19, 1996 (61 FR 11153).
C. The Libby PM10 Nonattainment Area
On August 7, 1987 (52 FR 29383), EPA identified a number of areas
across the country as PM10 ``Group I'' areas of concern,
that is, areas with a 95% or greater likelihood of violating the
PM10 NAAQS and requiring substantial planning efforts. The
Libby PM10 nonattainment area was identified as a Group I
area of concern.
Areas meeting the requirements of section 107(d)(4)(B) were
designated nonattainment for PM10 by operation of law and
classified ``moderate'' upon enactment of the 1990 Clean Air Act
Amendments. See 42 U.S.C. 7407(d)(4)(B). These areas included all
former Group I PM10 planning areas identified on August 7,
1987 (52 FR 29383), and other areas violating the NAAQS for
PM10 prior to January 1, 1989. On October 31, 1990 (55 FR
45799), EPA further clarified the descriptions of Group I and Group II
areas of concern listed in the August 7, 1987 (52 FR 29383) notice. A
Federal Register notice announcing the areas designated nonattainment
for PM10 upon enactment of the 1990 Clean Air Act
Amendments, known as ``initial'' PM10 nonattainment areas,
was published on March 15, 1991 (56 FR 11101). The Libby
PM10 nonattainment area was one of these initial moderate
PM10 nonattainment areas.
i. Attainment Date for the Libby PM10 Nonattainment Area
All initial moderate PM10 nonattainment areas had the
same applicable attainment date of December 31, 1994. States containing
initial moderate PM10 nonattainment areas were required to
develop and submit to EPA by November 15, 1991, a SIP revision
providing implementation of RACM, including RACT, and a demonstration
of whether attainment of the PM10 NAAQS by the December 31,
1994 attainment date was practicable. See section 189(a).
ii. PM10 Planning in the Libby PM10 Nonattainment
Area
After the Libby PM10 nonattainment area was designated
nonattainment for PM10, the MBHES began in the early 1990s
to prepare the technical elements needed to bring the area into
attainment and meet the planning requirements of Title I of the CAA.
Based on these technical elements, MBHES developed and implemented
control measures on PM10 sources in the Libby
PM10 nonattainment area. The Libby PM10 SIP was
originally adopted by the MBHES on November 15, 1991, and submitted to
EPA on November 25, 1991. Deficiencies were identified by EPA and
revisions were adopted by MBHES on March 19, 1993, and submitted to EPA
on May 24, 1993. Final technical corrections to the SIP were sent to
EPA on June 3, 1994. EPA approved the Libby PM10 SIP, with
the exception of the contingency measures, on August 30, 1994 (59 FR
44627). The Governor of Montana submitted revisions to the contingency
measures on March 15, 1995 and EPA approved the contingency measures on
September 30, 1996 (61 FR 51014).
III. Attainment Determination
A. What are the requirements for an attainment determination?
Generally, EPA determines whether an area's air quality is meeting
the PM10 NAAQS based upon complete, quality-assured data
gathered at established state and local air monitoring stations (SLAMS)
and national air monitoring stations (NAMS) in the nonattainment areas
and entered in the EPA Air Quality System (AQS). Data from air monitors
operated by state/local/tribal agencies in compliance with EPA
monitoring requirements must be submitted to AQS. EPA relies primarily
on data in AQS when determining the attainment status of an area. See
40 CFR 50.6; 40 CFR part 50, appendix J; and 40 CFR part 58, appendix
A. EPA will also consider air quality data from other air monitoring
stations in the nonattainment area provided that the stations meet the
federal monitoring requirements for SLAMS, including the quality
assurance and quality control criteria in 40 CFR part 58, appendix A.
40 CFR 58.14 (2006) and 58.20 (2007); \4\ 71 FR 61236, 61242 (October
17, 2006). All valid data are reviewed to determine the area's air
quality status in accordance with 40 CFR part 50, appendix K.
---------------------------------------------------------------------------
\4\ EPA promulgated amendments to the ambient air monitoring
regulations in 40 CFR parts 53 and 58 on October 17, 2006. See 71 FR
61236. The requirements for Special Purpose Monitors were revised
and moved from 40 CFR 58.14 to 40 CFR 58.20.
---------------------------------------------------------------------------
Attainment of the 24-hour PM10 standard is determined by
calculating the expected number of exceedances of the standard in a
year. The 24-hour standard is attained when the expected number of days
per calendar year with a 24-hour concentration above 154 [mu]g/m\3\ is
less than or equal to one. Generally, three consecutive years of air
quality data are required to show attainment of the 24-hour
PM10 standard.
B. What do the air quality data show for the Columbia Falls
PM10 nonattainment Area?
Because the Columbia Falls PM10 nonattainment area had a
December 31, 1994, attainment date, our determination of whether or not
the area attained the standard is based on 1992, 1993 and 1994 complete
quality-assured data for the area. During that period, the State of
Montana operated one PM10 SLAMS monitoring site at the
Columbia Falls Junior High School, which is within the Columbia Falls
nonattainment area. The monitoring site met EPA SLAMS network design
and siting requirements set forth at 40 CFR part 58, appendices D and
E. The Columbia Falls Junior High School monitor began operation on
April 21, 1987 and ceased operation on December 28, 2002.
Our review of complete quality-assured air quality data from the
Columbia Falls Junior High School site for the period from January 1,
1992 through December 31, 1994, shows no data values exceeded the level
of the 24-hour standard. Because there were no recorded exceedances of
the 24-hour
[[Page 5283]]
PM10 standard during calendar years 1992-1994, the estimated
number of PM10 exceedances for the 1992-1994 period is 0.0,
as seen in Figure 1. Therefore, the Columbia Falls nonattainment area
has demonstrated attainment for the 24-hour PM10 NAAQS as of
the attainment date of December 31, 1994. Additionally, we evaluated
complete quality-assured air quality data at all monitors within the
Columbia Falls PM10 nonattainment area after the attainment
date of December 31, 1994 to 2009 and found no recorded exceedances.

C. What do the air quality data show for the Libby PM10
nonattainment area?
Because the Libby PM10 nonattainment area had a December
31, 1994, attainment date, our determination of whether or not the area
attained the standard is based on 1992, 1993 and 1994 complete quality-
assured data for the area. During that period, the State of Montana
operated two PM10 SLAMS monitoring sites within the Libby
nonattainment area: the Lincoln County Courthouse site and the Libby
Courthouse Annex site. Both monitoring sites met EPA SLAMS network
design and siting requirements set forth at 40 CFR part 58, appendices
D and E. The Lincoln County Courthouse monitor began operation on April
21, 1987 and ceased operation on March 31, 1995. The Libby Courthouse
Annex monitor began operating on October 8, 1993 and continues to
operate.
Our review of complete quality-assured air quality data from the
Lincoln County Courthouse site and the Libby Courthouse Annex site for
the period from January 1, 1992 through December 31, 1994, shows no
data values exceeded the level of the 24-hour standard. Because there
were no recorded exceedances of the 24-hour PM10 standard
during calendar years 1992-1994, the estimated number of
PM10 exceedances for the 1992-1994 period is 0.0, as seen in
Figure 2. Therefore, the Libby nonattainment area has demonstrated
attainment for the 24-hour PM10 NAAQS as of the attainment
date of December 31, 1994. Additionally, we evaluated complete quality-
assured air quality data at all monitors within the Libby
PM10 nonattainment area after the attainment date of
December 31, 1994 to 2009 and found no recorded exceedances.

IV. EPA's Final Action
EPA is determining that the Columbia Falls and Libby areas have
attained the PM10 standard based on the three years of
complete, quality-assured data as of the attainment date of December
31, 1994. For the period from 1992-1994, the expected exceedance for
both areas is 0.0, which is equal to or less than the expected
exceedance rate of 1.0 (40 CFR part 50, appendix K). Because complete
quality-assured data for this period shows an expected exceedance rate
equal to or below the PM10 standard, EPA concludes that the
areas have met the standard. Pursuant to CAA Sec. 188(c), EPA is
required to make a determination of attainment. There were no
violations and therefore no health risk. EPA therefore determines that
the Columbia Falls and Libby nonattainment areas have attained the 24-
hour PM10 NAAQS as of the December 31, 1994 attainment date.
V. Statutory and Executive Order Review
Under the Clean Air Act, the Administrator is required to approve a
SIP submission that complies with the provisions of the Act and
applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a).
Thus, in reviewing SIP submissions, EPA's role is to approve state
choices, provided that they meet the criteria of the Clean Air Act.
Accordingly, this action merely approves state law as meeting Federal
requirements and does not impose additional requirements beyond those
imposed by state law. For that reason, this action:
Is not a ``significant regulatory action'' subject to
review by the Office of Management and Budget under Executive Order
12866 (58 FR 51735, October 4, 1993);
Does not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
Is certified as not having a significant economic impact
on a substantial number of small entities under the Regulatory
Flexibility Act (5 U.S.C. 601 et seq.);
Does not contain any unfunded mandate or significantly or
uniquely affect small governments, as described in the Unfunded
Mandates Reform Act of 1995 (Pub. L. 104-4);
Does not have Federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
Is not an economically significant regulatory action based
on health or safety risks subject to Executive Order 13045 (62 FR
19885, April 23, 1997);
Is not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001);
Is not subject to requirements of Section 12(d) of the
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272
note) because application of those requirements would be inconsistent
with the Clean Air Act; and
Does not provide EPA with the discretionary authority to
address, as appropriate, disproportionate human health or environmental
effects, using practicable and legally permissible methods, under
Executive Order 12898 (59 FR 7629, February 16, 1994).
In addition, this rule does not have tribal implications as
specified by Executive Order 13175 (65 FR 67249, November 9, 2000),
because the SIP is not approved to apply in Indian country located in
the state, and EPA notes that it will not impose substantial direct
costs on tribal governments or preempt tribal law.
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the
Small Business Regulatory Enforcement Fairness Act of 1996, generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report, which includes a copy of the rule,
to each House of the Congress and to the Comptroller General of the
United States. EPA will submit a report containing this action and
other required information to the U.S. Senate, the U.S. House of
Representatives, and the Comptroller General of the United States prior
to publication of the rule in the Federal Register. A major rule cannot
take effect until 60 days after it is published in the Federal
Register. This action is not a ``major rule'' as defined by 5 U.S.C.
804(2).
Under section 307(b)(1) of the Clean Air Act, petitions for
judicial review of this action must be filed in the United States Court
of Appeals for the appropriate circuit by April 1, 2011. Filing a
petition for reconsideration by the Administrator of this final rule
does not affect the finality of this action for the purposes of
judicial review nor does it extend the time within which a petition for
judicial review may be filed, and shall not postpone the effectiveness
of such rule or action. Parties with objections to this direct final
rule are encouraged to file a comment in response to the parallel
notice of proposed rulemaking for this action published in the proposed
rules section of today's Federal Register, rather than file an
immediate petition for judicial review of this direct final rule, so
that EPA can withdraw this direct final rule and address the comment in
the proposed rulemaking. This action may not be challenged later in
proceedings to enforce its requirements. See section 307(b)(2).
