I. Background
A. PM10 NAAQS
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. 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 in excess of the standard, as determined in accordance
with 40 CFR part 50, appendix K, is equal to or less than one.\1\ 40
CFR 50.6 and 40 CFR part 50, appendix K.
---------------------------------------------------------------------------
\1\ 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]/m\3\ whereas a
recorded value of 155 [mu]g/m\3\ would be an exceedance since it
would be rounded to 160 [mu]/m\3\. See 40 CFR part 50, appendix K,
section 1.0.
---------------------------------------------------------------------------
B. Designation and Classification of PM10 Nonattainment
Areas
Areas meeting the requirements of section 107(d)(4)(B) of the Clean
Air Act (CAA or the Act) were designated nonattainment for
PM10 by operation of law and classified ``moderate'' upon
enactment of the 1990 Clean Air Act Amendments. See generally 42 U.S.C.
7407(d)(4)(B). These areas included all former Group I PM10
planning areas identified in 52 FR 29383 (August 7, 1987), as further
clarified in 55 FR 45799 (October 31, 1990), and any other areas
violating the NAAQS for PM10 prior to January 1, 1989. A
Federal Register notice announcing the areas designated nonattainment
for PM10 upon enactment of the 1990 Amendments, known as
``initial'' PM10 nonattainment areas, was published on March
15, 1991 (56 FR 11101) and a subsequent Federal Register document
correcting the description of some of these areas was published on
August 8, 1991 (56 FR 37654). The Sandpoint PM10
nonattainment area was one of these initial moderate PM10
nonattainment areas.
All initial moderate PM10 nonattainment areas had the
same applicable attainment date of December 31, 1994. Section 188(d)
provides the Administrator the authority to grant up to two one-year
extensions to the attainment date provided certain requirements are
met. States containing initial moderate PM10 nonattainment
areas were required to develop and submit to EPA by November 15, 1991,
a state implementation plan (SIP) revision providing implementation of
reasonably available control measures (RACM), including reasonably
available control technology (RACT), and a demonstration of whether
attainment of the PM10 NAAQS by the December 31, 1994
attainment date was practicable. See section 189(a).
C. How does EPA make attainment determinations?
All PM10 nonattainment areas are initially classified
``moderate'' by operation of law when they are designated
nonattainment. See section 188(a). Section 188(b)(2) of the Act
requires EPA to determine within six months of the applicable
attainment date whether, based on air quality data, PM10
nonattainment areas attained the PM10 NAAQS by that date.
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 into 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; 40 CFR part 53; 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); \2\ 71 FR 61236,
61242 (October 17, 2006). All valid data are reviewed to determine the
area's air quality status in
[[Page 35304]]
accordance with 40 CFR part 50, appendix K.
---------------------------------------------------------------------------
\2\ 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 exceedances
averaged over a three-year period 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. See 40 CFR
part 50 and appendix K.\3\
---------------------------------------------------------------------------
\3\ Because the annual PM10 standard was revoked
effective December 18, 2006, see 71 FR 61144 (October 17, 2006),
this notice discusses only attainment of the 24-hour PM10
standard.
---------------------------------------------------------------------------
D. What is the attainment date for the Sandpoint PM10
nonattainment area?
The original attainment date for the Sandpoint PM10
nonattainment area was December 31, 1994. The attainment date was later
extended to December 31, 1995, and then to December 31, 1996, under the
authority of section 188(d) of the Act. See 61 FR 20730 (May 8, 1996)
(first one-year extension); 61 FR 66602 (December 18, 1996) (second
one-year extension).
E. What PM10 planning has occurred for the Sandpoint
PM10 nonattainment area?
After the Sandpoint PM10 nonattainment area was
designated nonattainment for PM10, the Idaho Department of
Environmental Quality (IDEQ), 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 products IDEQ developed and implemented control measures on
PM10 sources in the Sandpoint PM10 nonattainment
area. The State submitted these control measures to EPA on August 16,
1996, as a moderate PM10 nonattainment SIP revision under
section 189(a) of the Act. The control measures submitted by the State
include a comprehensive residential wood combustion program, controls
on fugitive road dust and emission limitations on industrial sources.
EPA took final action to approve the State's moderate PM10
SIP on June 26, 2002. See 67 FR 43006.
II. EPA's Analysis
A. What does the air quality data show as of the December 31, 1996
attainment date?
The State of Idaho operated a PM10 SLAMS monitoring site
in the Sandpoint PM10 nonattainment area at the Sandpoint
Post Office until October 2001. A new site was established in Sandpoint
in November 2001 at 310 South Division Street. This site continued
operation through March 2009. In March 2009 the site was moved to 1601
Ontario Street in Sandpoint. All three sites meet Federal siting
requirements and are appropriate for monitoring the area's compliance
with the PM10 NAAQS. (See EPA's letters approving Idaho's
annual network review.)
Based on a review of air quality data during the three-year period
ending with the December 31, 1996 attainment date, one 24 hour
PM10 concentration, reported on January 26, 1994, exceeded
the level of the 24 hour NAAQS, but this single exceedance did not
cause a violation of the 24 hour NAAQS for the calendar years 1994-
1996. The expected exceedance rate for the Sandpoint area for 1994-1996
is 0.7 days per year. This is less than the expected exceedance rate of
the 24 hour NAAQS of 1.0 and demonstrates attainment of the 24-hour
PM10. EPA has therefore determined that the Sandpoint
PM10 nonattainment area attained the PM10 NAAQS
by the extended attainment date of December 31, 1996.
B. Does more recent air quality data also show attainment?
Although the attainment date for the Sandpoint PM10
nonattainment area is December 31, 1996, EPA has also reviewed the air
quality data collected at the State monitoring sites in the Sandpoint
area from January 1997 through December 2009. The data continue to show
attainment of the 24 hour PM10 NAAQS during this period. The
monitoring site at the Post Office reported no exceedances of the 24
hour NAAQS from 1997 until it was discontinued in 2001. The new
monitoring site at 310 South Division Street, which began monitoring in
2001, likewise reported no exceedances of the 24 hour NAAQS from 2001
through 2009.
III. Statutory and Executive Order Reviews
This action proposes to make a determination based on air quality
data, and would, if finalized, not result in the imposition of any
additional Federal requirements. For that reason, this proposed action:
Is not a ``significant regulatory action'' subject to
review by the Office of Management and Budget under Executive Order
12866 (58 FR 51735, October 4, 1993);
Does not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
Is certified as not having a significant economic impact
on a substantial number of small entities under the Regulatory
Flexibility Act (5 U.S.C. 601 et seq.);
Does not contain any unfunded mandate or significantly or
uniquely affect small governments, as described in the Unfunded
Mandates Reform Act of 1995 (Pub. L. 104-4);
Does not have Federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
Is not an economically significant regulatory action based
on health or safety risks subject to Executive Order 13045 (62 FR
19885, April 23, 1997); is not a significant regulatory action subject
to Executive Order 13211 (66 FR 28355, May 22, 2001);
Is not subject to requirements of Section 12(d) of the
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272
note) because application of those requirements would be inconsistent
with the CAA; and
Does not provide EPA with the discretionary authority to
address, as appropriate, disproportionate human health or environmental
effects, using practicable and legally permissible methods, under
Executive Order 12898 (59 FR 7629, February 16, 1994).
In addition, this rule does not have tribal implications as
specified by Executive Order 13175 (65 FR 67249, November 9, 2000),
because it does not apply in Indian country located in the State, and
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 August 23, 2010.
[[Page 35305]]
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).)
