Approval and Promulgation of Air Quality Implementation Plans;
Illinois; Indiana; Chicago and Evansville Nonattainment Areas;
Determination of Attainment of the Fine Particle Standards
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: EPA is determining that the Chicago-Gary-Lake County,
Illinois-Indiana (``Chicago'') and Evansville, Indiana nonattainment
areas have attained the 1997 fine particle (PM2.5) National
Ambient Air Quality Standard (NAAQS). These determinations are based
upon quality-assured and certified ambient air monitoring data that
show that the areas have monitored attainment of the 1997
PM2.5 NAAQS for the 2006 to 2008 monitoring period.
Currently available preliminary data for 2009 are consistent with
continued attainment of the standard. As a result of these
determinations, the requirements for these areas to submit an
attainment demonstration and associated reasonably available control
measures (RACM), a reasonable further progress plan (RFP), contingency
measures, and other State Implementation Plan (SIP) revisions related
to attainment of the standard are suspended for so long as the areas
continue to attain the 1997 PM2.5 NAAQS.
DATES: This final rule is effective on November 27, 2009.

VI. Statutory and Executive Order Reviews
I. What Actions Is EPA Taking?
EPA is determining that the Chicago nonattainment area (including
portions in Illinois and Indiana) and the Evansville, Indiana
nonattainment area have attained the 1997 PM2.5 NAAQS. These
determinations are based upon quality-assured and certified ambient air
monitoring data that show that the areas have monitored attainment of
the 1997 PM2.5 NAAQS for the 2006-2008 monitoring period.
Preliminary data available to date for 2009 are consistent with
continued attainment of the standard.
II. What Did EPA Propose?
EPA proposed that the Chicago area (including portions in Illinois
and Indiana) and the Evansville, Indiana area have attained the 1997
PM2.5 NAAQS. EPA published these proposed determinations on
September 24, 2009, at 74 FR 48690. Further details of EPA's review are
available in the proposed rule.
A. Chicago Area
EPA reviewed the ambient air monitoring data for the Chicago area
in accordance with the provisions of 40 CFR Part 50 Appendix N. All
data considered have been recorded in EPA's Air Quality System (AQS)
database. The review primarily addressed air quality data collected in
the three-year period from 2006 to 2008.
Of sites with data to be compared to the annual standard, the
highest three-year average annual concentration for 2006 to 2008 in the
Chicago area was recorded at the Schiller Park site, site number 17-
031-3103, observing a three-year average annual concentration of 14.6
micrograms per cubic meter ([mu]g/m\3\). As discussed in the proposed
rule, even the sites that are not for comparison to the annual standard
are observing average concentrations below the standard. The highest
98th percentile 24-hour average concentration is recorded at the McCook
site, site number 17-031-1016, recording a three-year average 98th
percentile 24-hour average concentration of 35 [mu]g/m\3\. Thus, all
sites in the area have three-year average annual PM2.5
concentrations below 15.0 [mu]g/m\3\ and three-year average 98th
percentile 24-hour average concentrations far below the 1997 standard
of 65 [mu]g/m\3\.\1\ See 74 FR 48692, including footnote 1.
---------------------------------------------------------------------------
\1\ EPA erroneously reported the annual average for the Burr
Street site, site number 18-089-0026, as 14.9 [mu]g/m\3\; the
correct value is 14.8 [mu]g/m\3\.
---------------------------------------------------------------------------
Further consideration of concentrations at Cicero, site 17-031-
6005, was necessary because data at this site do not meet completeness
requirements, and because the site monitored a violation for the most
recent three years with complete data, i.e. 2005 to 2007. A detailed
review of concentrations at the Cicero site in relation to
concentrations at other similar sites in the Chicago area is provided
in the proposed rule. Based on this review, EPA stated its belief that
the Cicero site, like other sites in the area, is attaining the
PM2.5 standards for the 2006 to 2008 period. 74 FR 48692-
48693.
In addition, the averages of available 2009 data from all monitors
still operating in the Chicago nonattainment area are at or below the
average for corresponding periods in 2006 to 2008, and the 98th
percentile of available 24-hour average concentrations is again more
than 30 [mu]g/m\3\ below the pertinent standard. Therefore, the
available data for 2009 are consistent with the finding, based on 2006
to 2008 data, that the Chicago area is attaining the 1997
PM2.5 standards.
B. Evansville Area
EPA reviewed the ambient air monitoring data for the Evansville
area in accordance with the provisions of 40 CFR Part 50 Appendix N.
All data considered have been recorded in EPA's AQS database. The
review primarily addressed air quality data collected at six monitoring
sites in the three-year period from 2006 to 2008.
The highest annual average PM2.5 concentration in the
Evansville nonattainment area for the 2006-2008 monitoring period was
13.7 [mu]g/m\3\, which occurred both at the Jasper Golf site (site 18-
037-0005, in Dubois County) and at the Evansville/West Mill Road site
(site 18-163-0012, in Vanderburgh County). The Evansville area also has
four additional monitors with data for 2006 to 2008, at which the 2006-
2008 three-year average annual concentrations ranged from 13.4 to 13.6
[mu]g/m\3\. The average 98th percentile 24-hour concentrations ranged
from 28 to 32 [mu]g/m\3\. Thus, the Evansville area is observing
concentrations well below the 1997 standards of 15.0 [mu]g/m\3\ and 65
[mu]g/m\3\, respectively.
The proposed rule notes a completeness criterion that a site record
valid data for at least 75 percent of the scheduled sampling days for
each quarter within the applicable three-year period. See 40 CFR 50
Appendix N 4.1. Three sites in the Evansville area, namely the
Evansville/West Mill Road site in Vanderburgh County and the Jasper
Golf site and the Jasper Sport Complex site in Dubois County, did not
meet this completeness criterion. For these sites, as explained in the
proposal (74 FR 48694), EPA conducted a conservative data substitution
analysis, assessing whether the site would still have observed
attainment under the hypothesis that the monitor on the days of missed
samples might have recorded the highest concentration that the monitor
observed during the applicable quarter during the 2006 to 2008
period.\2\ Both the Jasper Golf site and the Evansville/West Mill Road
site had one or more quarters in 2006 to 2008 that measured less than
75 percent complete data, but in both cases the substitution analysis
indicates that the monitors would have shown attainment even with
conservative assumptions about the missing data.
---------------------------------------------------------------------------
\2\ This conservative substitution test to confirm a passing
design value that is based on incomplete data is explained in the
EPA guidance document ``Guideline On Data Handling Conventions For
The PM NAAQS,'' EPA-454/R-99-008, April 1999, at page 16. (http://www.epa.gov/ttn/oarpg/t1/memoranda/pmfinal.pdf).
---------------------------------------------------------------------------
At the Jasper Sport Complex site (site 18-037-0004, in Dubois
County), the data substitution approach using the highest concentration
that the monitor observed during the applicable quarter during the 2006
to 2008 period did not yield a firm conclusion as to whether the site
is attaining the annual standard. This site began operation in early
2006 (January 29, 2006), and so earlier (e.g. 2005 to 2007) three-year
averages were not available. As EPA explained in its proposal (74 FR
48694), another method available to evaluate these data is to examine
the data at this site in relation to data at other similar sites in the
area, to judge the likelihood that the monitor
[[Page 62245]]
would have shown attainment had it collected complete data. The
available data at this site have always indicated annual average
concentrations below 15.0 [mu]g/m\3\ and 24-hour concentrations below
65 [mu]g/m\3\. The available data at this site are similar to the data
at other nearby sites in the area. Therefore, EPA believes this site,
like the other sites in the Evansville area, is attaining the
standards. In addition, all sites with data from 2005 to 2007 recorded
measurements showing attainment for that period as well. Therefore, EPA
proposed to find that all sites in the Evansville area, including sites
that did not meet the 75 percent completeness requirement, are now
meeting the 1997 NAAQS. See 40 CFR 50 Appendix N 4.1 and 4.2.
In addition, EPA examined data from the first half of 2009. For
each site, the average of available 2009 data is at or below the
average for corresponding periods in 2006 to 2008 and the 98th
percentile of available 24-hour average concentrations is again more
than 30 [micro]g/m\3\ below the pertinent standard. Therefore, EPA
observed that the available data for 2009 are consistent with the
finding, based on 2006 to 2008 data, that the Evansville area is
attaining the 1997 PM2.5 standards.
III. What Comments Did EPA Receive and What Are EPA's Responses?
EPA received a total of four sets of comments in response to these
actions, including comments by Indiana Steel Environmental Group
(ISEG), the Northwest Indiana Forum, Valley Watch, Inc., and one
anonymous commenter. ISEG and the Northwest Indiana Forum supported
EPA's proposed determinations of attainment of the 1997
PM2.5 NAAQS for the Chicago and Evansville areas. In this
section, EPA responds to the adverse comments received in response to
the September 24, 2009, proposed rulemaking. EPA did not receive any
adverse comments specifically directed at its proposed determination of
attainment for the Chicago area.
Comment: Valley Watch requests that EPA accept its ``comments
objecting to EPA's proposal to redesignate the Evansville, IN area to
`attainment' of the 1997 standard for PM2.5.'' Valley Watch
also submitted to this rulemaking the same comments that it submitted
to the Indiana Department of Environmental Management (IDEM) in March
2008, at a State hearing on the State's planned petition for
redesignation of the Evansville area. Many of those comments include
contentions about the health effects of PM2.5, the status of
the Clean Air Interstate Rule (CAIR), and the potential impact of new
power plants that Valley Watch believes will increase emissions of fine
particulate matter precursors. Valley Watch also expressed its concern
that the recent economic downturn is responsible for temporary
decreases in concentrations of PM2.5, and thus the ``low''
levels of particulate matter being measured are not due to permanent
and enforceable emissions limitations.
Response: As EPA stated in its proposal (74 FR 48695), EPA in this
rulemaking is merely determining that the Evansville area is attaining
the 1997 PM2.5 standards, based on the most recent three
years of quality assured air monitoring data. EPA is not redesignating
the area under section 107(d)(3)(E) of the Clean Air Act (CAA). EPA is
not evaluating whether any of the other criteria for redesignation, as
set forth in section 107(d)(3)(E) of the CAA, have been met. The only
issue before EPA in this rulemaking is whether the air quality
monitored in the area meets the 1997 PM2.5 standards.
Therefore, any comments that address other issues pertaining to
redesignation, and that do not address the question of whether, as a
matter of air quality, the area is attaining the 1997 PM2.5
standards, are not relevant to this rulemaking. For example, the causes
of air quality levels--whether they are due to permanent and
enforceable emissions reductions and whether such reductions will be
maintained over time--are not addressed in a determination of
attainment. Nor is there any relevance for this rulemaking of
commenter's assertions regarding the impact of CAIR or other regulatory
regimes or emissions from prospective new power plants. If, in the
future, EPA determines that the area has lapsed out of attainment with
the standards, EPA would take action to withdraw its determination of
attainment. Thus, comments addressing issues other than whether air
quality currently meets the 1997 PM2.5 standards are not
relevant to this determination of attainment.
Comment: Valley Watch contends that there are ``huge gaps'' in the
data for 2006-2007, and that this action should not go forward until
more data are collected. The commenter claims that gaps of 13 percent
and 16 percent occurred in 2006 and 2007, respectively, when
``mysteriously or perhaps fraudulently data seemed to just disappear at
times when fine particle levels were elevating at other regional
monitors.'' Valley Watch submitted these comments to Indiana on March
27, 2008, in response to a State solicitation of comments on a
prospective request for redesignation of the Evansville area; Valley
Watch then attached those comments to its comments on EPA's proposed
clean data determination.
The commenter focuses on data at the Evansville Civic Center
monitor (site number 18-163-0006). The commenter in particular notes
for this site that ``[i]n June, six out of ten measurements are
missing. In August, five out ten measurements are also missing.''
Response: The Evansville Civic Center site has two operating
instruments. The shortfall in data collection noted by the commenter
occurred in 2007 for one of these instruments (``Instrument 1'').
However, many of the days lacking valid data at Instrument 1 had valid
data at Instrument 2. Since both instruments collect equally valid
data, EPA views valid data from Instrument 2 as a suitable substitute
for missing data from Instrument 1, and in fact EPA treats the site as
having valid data for such days.\3\ In particular for June and August
of 2007, EPA finds that seven of the ten scheduled sampling days in
June 2007 and nine of the eleven scheduled sampling days in August 2007
had valid data. Similarly for the full year, using data from Instrument
2 where data are missing from Instrument 1, EPA finds for 2007 for
example that this site has valid data for 92 percent of the days, not
84 percent.
---------------------------------------------------------------------------
\3\ The use of data from a second instrument in place of missing
data from the first instrument is explained in the EPA guidance
document ``Guideline On Data Handling Conventions For The PM
NAAQS,'' EPA-454/R-99-008, April 1999, at page 16. (http://www.epa.gov/ttn/oarpg/t1/memoranda/pmfinal.pdf)
---------------------------------------------------------------------------
The commenter expresses concern that the days it considers to lack
data may disproportionately be days with high concentrations. Indeed,
for the six days in the two months at the site especially in question
(June and August 2007 at the Civic Center site) for which Instrument 2
obtained valid data and Instrument 1 did not, the average concentration
was 20.0 [mu]g/m\3\. The commenter may believe that availability of
more complete data and inclusion of that data in the calculation of
average concentrations at the Civic Center would have yielded a
computed violation. However, in EPA's view, a majority of the days that
the commenter considers to lack data in fact have data, and EPA
included those data in its computation of average concentrations. The
results, as reported in the proposed rulemaking, are well below the
applicable standard. EPA has no reason to believe that the days without
data on average would have had concentrations higher (or lower) than
the average for the applicable quarter, e.g., that the days without
data in the third quarter of 2007
[[Page 62246]]
at this site on average would have had concentrations higher than the
quarterly average of 18.27 [mu]g/m\3\, much less that the data on
average would have been enough higher to yield a three-year average
greater than 15.0 [mu]g/m\3\. Inasmuch as the combined data set from
the two instruments meets the data completeness requirements of 40 CFR
part 50 Appendix N 4.1(b), EPA believes that sufficient data are
available to have adequate confidence in the result, i.e., that the
site is attaining the standards.
EPA computes annual average concentration through a multi-step
process in which it first computes quarterly average concentrations and
then computes each year's average concentration as an average of the
four quarterly average concentrations. This process assures that the
four quarters are equally represented in the computation of the annual
average, so that differences in the data completeness for different
quarters do not influence the computed annual average. EPA agrees that
summer concentrations in Evansville tend to be higher than
concentrations at other times of year, but EPA does not expect a modest
number of missing summer values (e.g., for the Civic Center site in
2007, 3 values in June and 2 values in August) to introduce any
significant potential for bias in the average values for the respective
quarters that are used in computing the annual average.
The proposed rulemaking addressed a number of issues relating to
data completeness. The proposal notes EPA's completeness criterion that
a site have valid data for at least 75 percent of the scheduled samples
in all twelve quarters of the applicable three years, reflecting EPA's
view that this quantity of data provides an adequate representation of
each quarter, i.e., EPA has adequate confidence that a complete data
set would not be expected to show a significantly different average (or
peak) concentration. The proposed rulemaking also addresses three sites
(not including the Civic Center site; instead including the West Mill
Road site in Vanderburgh County (site 18-163-0012) and the Jasper
Sports Complex and Jasper Golf sites (sites 18-037-0004 and 18-037-
0005) in Dubois County) that had quarters with less than 75 percent
data capture, describing the data substitution analyses that EPA
performed to assess whether it is plausible that complete data would
have shown these sites to violate the standards.
The commenter did not comment on any of this discussion in the
proposed rulemaking. Specifically, the commenter did not comment on
EPA's 75 percent completeness criterion, and the commenter did not
comment on the analyses EPA conducted for sites for which that
criterion was unmet. Indeed, by excluding the Civic Center site from
its list of sites not meeting this completeness criterion, EPA made
clear that it viewed the Civic Center as meeting this completeness
criterion, and yet the commenter did not expressly challenge this EPA
view. Furthermore, the commenter made no mention of the Dubois County
sites, to which a majority of the Evansville area data completeness
issues apply. As a result, EPA has no reason to change its views on the
completeness criterion, the application of that criterion to the
Evansville area, the analyses of Evansville air quality data, or the
conclusion that EPA has adequate confidence that the Evansville area is
attaining the 1997 air quality standards. EPA finds there is no
evidence that data have ``fraudulently'' or ``mysteriously''
disappeared, as commenter contends. Valley Watch's comments on the
State's redesignation request were submitted prior to the time that
calendar year data for 2008 were recorded and quality-assured and
certified. After Valley Watch's comments on the redesignation request
were submitted, more data have been acquired and evaluated for purposes
of EPA's determination of attainment. Thus Valley Watch's analysis
contained only a partial and outdated review of the relevant data. EPA
finds no need for an additional ``independent'' analysis that was
requested by the commenter in its comments on redesignation.
Comment: Valley Watch, in its March, 2008 comments on the request
for redesignation that IDEM had proposed, included criticisms of 2004
and 2005 data, and requested that the redesignation be stopped ``until
at least another year of data is collected'' in order to see air
quality trends.
Response: EPA is making its determination of attainment based on
2006-2008 quality-assured data, rather than 2004-2006 data. Although in
fact EPA believes that Evansville attained the standards based on 2004
to 2006 data, air quality for that period are not relevant to EPA's
determination that the area is currently attaining the standards. The
commenter prepared the substance of his analysis of the data in March
2008, and did not update his review to include the more recent data
used by EPA, or EPA's evaluation and conclusions with respect to those
data. It has now been more than a year and a half since Valley Watch
submitted its March 2008 comments, and more than another year of data
has been collected which shows continued attainment of the
PM2.5 standards. Thus commenter's wish for another year of
quality-assured data has been satisfied.
Comment: The commenter includes a series of comments related to
criteria for redesignation that do not bear on the question of whether
or not the area is currently attaining the standard. The commenter
contends that ``Utility executives that Valley Watch has consulted
indicate that throughout 2008 and 2009 electrical generation demand has
reduced nearly 25% in the region.'' The commenter argues that this
decrease in demand would yield a commensurate reduction in the
formation of fine particles and that economic recovery will result in a
rise of electrical production and fine particle levels; thus this
decrease ``cannot be considered as federally enforceable for
redesignation purposes.'' Further, ``[n]umerous, already under
construction, approved or soon to be approved new coal plants will add
to an already fragile `attainment' of the NAAQS for fine particles.''
Response: EPA's determination here is limited to a finding that the
area's air quality currently meets the 1997 PM2.5 standards.
Unlike the case for redesignations, EPA need not evaluate whether the
air quality improvement is due to permanent and enforceable reductions,
and projections as to whether the air quality standards will be
maintained in the future also are not germane to EPA's determination of
attainment here. Moreover, the future impact of new sources and
potential new sources on the area has and will be assessed in the
context of permitting of those sources. For the reasons set forth in
the discussions of EPA's review of the data in this final rulemaking
and in its proposal, EPA does not agree with the commenter's
contentions that currently monitored levels are too close to the 1997
standards for EPA to make determinations of attainment, or that the
data recorded at the monitors are ``skewed low''. In the future, if EPA
determines that the area no longer is attaining the standards, EPA will
take action, after notice-and-comment rulemaking, to withdraw its
determination.
Comment: The commenter states that ``EPA's Clean Air Scientific
Advisory Committee (CASAC), a blue ribbon panel of scientists,
recommended in 2005 and 2006 that the annual NAAQS for fine particles
be set at a level as low as 13 [micro]g/m\3\ and no higher than 14
[micro]g/m\3\.'' In addition, ``[a]s further proof that residents of
this area are forced to breathe unhealthy air, a study conducted by the
Partnership for Healthcare Information through the
[[Page 62247]]
University of Southern Indiana found that `In 1996, Vanderburgh County
had a hospitalization rate of 51.7 per 10,000 versus 32.2 per 10,000 in
Allen County for the 0-3 age group; for the 4-8 year old group,
Vanderburgh County's rate was 35.2 while Allen County's rate was 10.5;
and the 9-13 year group showed 40.2 for Vanderburgh County and 8.3 for
Allen County.' ''
Response: This rulemaking addresses whether air quality in the
Evansville area is meeting the 1997 PM2.5 air quality
standards, based on the most recent quality-assured monitoring data. It
is not relevant to this determination that EPA has subsequently lowered
the 24-hour standard or that the commenter believes EPA should have set
the annual standard lower. Challenges to the PM2.5 standards
have been raised in other proceedings, and are not properly brought
here. Moreover, the historical study of health indicators in
Vanderburgh and Allen Counties, which cites to information collected in
1996, and the question of whether the current air quality standards are
health protective, are not relevant to the only question at issue here,
which is whether the Evansville area is meeting the 1997
PM2.5 standards that are in place.
Based on the reasons previously discussed, EPA continues to believe
that determinations of attainment are warranted for the Chicago
(Illinois and Indiana) and Evansville (Indiana) areas.
Comment: Valley Watch makes numerous allegations reflecting a view
that the Evansville data and the officials responsible for collecting
and reporting these data are not to be trusted. These comments include
allegations that the local agency may have avoided collecting data
particularly on days with high concentrations. The commenter seeks
investigation of a discrepancy between the value reported by the local
agency versus the value reported by the State for July 7, 2007. The
commenter believes that EPA's computation involves rounding of a value
above the standard to a value found to meet the standard; the commenter
finds this a problematic ``bureaucratic spin.'' The commenter contends
that, given the missing data, the commenter finds the values too close
to the standard to be sure that the area is meeting the standard.
Response: The commenter provides no credible evidence to justify
the allegations that are lodged. Most relevantly here, EPA finds no
reason to question the data that the State has certified as accurate,
and EPA has no grounds for believing that the collected data are
unrepresentative of the quarters during which they were collected. EPA
used values reported in the AQS, not the values in either of the
reports cited by the commenter, and, in any case, EPA finds that July
7, 2007 was not a scheduled sampling day and evidently no concentration
measurements were made.\4\ The comments regarding rounding and being
close to the standard are not relevant to data from 2006 to 2008, which
show annual average concentrations at all sites (with or without
rounding as dictated under Appendix N) being more than 1 [mu]g/m\3\
below the standard.
---------------------------------------------------------------------------
\4\ The monitor at issue with regard to July 7, 2007 (at site
number 18-163-0012) was operating on an every third day schedule in
2007. The dates of sampling for this schedule are set by EPA so that
the same days are monitored in all locations, and are posted at
http://www.epa.gov/ttn/amtic/files/ambient/pm25/cal2007.pdf.
---------------------------------------------------------------------------
Comment: An anonymous commenter stated the view that ``cities are
absolutely disgusting,'' and that ``they are getting way out of
control. We need to do whatever it takes to clean them up!''
Response: This comment does not address the actual air quality
levels for the Chicago and Evansville areas or how those levels compare
to the 1997 PM2.5 NAAQS. It is thus not germane to whether
the Chicago and Evansville areas are attaining those standards.
IV. What Is the Effect of These Actions?
On the basis of this review, EPA is determining that the Chicago
area and the Evansville area have attained the 1997 PM2.5
NAAQS based on 2006-2008 data. In addition, monitoring data for 2009
that are available to date in the EPA AQS database, but not yet
certified, indicate that these areas continues to attain the 1997
PM2.5.
Under the provisions of EPA's PM2.5 implementation rule
(see 40 CFR 51.1004(c)), the requirements for Illinois and Indiana to
submit attainment demonstrations and associated RACM, RFPs, contingency
measures, and any other planning SIPs related to attainment of the 1997
PM2.5 NAAQS for the Chicago and Evansville PM2.5
nonattainment areas are suspended for so long as the areas continue to
attain the 1997 PM2.5 NAAQS.
As further discussed below, these determinations will: (1) For the
Chicago and Evansville nonattainment areas, suspend the requirements
for the submittal of attainment demonstrations and associated RACM,
RFPs, contingency measures, and any other planning SIP revisions
related to attainment of the 1997 PM2.5 NAAQS; (2) continue
until such time, if any, that EPA subsequently determines that one of
the areas has violated the 1997 PM2.5 NAAQS; (3) be separate
from, and not influence or otherwise affect, any future designation
determination or requirements for the Chicago and Evansville areas
based on the 2006 PM2.5 NAAQS; and (4) remain in effect
regardless of whether EPA designates these areas as nonattainment areas
for purposes of the 2006 PM2.5 NAAQS. Furthermore, as
described below, any such final determination is not equivalent to the
redesignation of the area to attainment based on the 1997
PM2.5 NAAQS.
If EPA subsequently determines, after notice-and-comment rulemaking
in the Federal Register, that either or both areas have violated the
1997 PM2.5 NAAQS, the basis for the suspension of the
specific requirements, set forth at 40 CFR 51.1004(c), would no longer
exist for the pertinent area(s), and EPA would take action to withdraw
the determination and direct the pertinent area(s) to address the
suspended requirements.
The determinations that the air quality data show attainment of the
1997 PM2.5 NAAQS are not equivalent to the redesignation of
the areas to attainment. These actions do not constitute a
redesignation to attainment under 107(d)(3) of the CAA, because we do
not yet have approved maintenance plans for the areas as required under
175A of the CAA, nor have we determined whether the areas have met the
other requirements for redesignation. The designation status of the
areas will remain nonattainment for the 1997 PM2.5 NAAQS
until such time as EPA determines that the areas meet the CAA
requirements for redesignation to attainment.
These actions are limited to determinations that the Chicago and
Evansville areas have attained the 1997 PM2.5 NAAQS. The
1997 PM2.5 NAAQS became effective on July 18, 1997 (62 FR
36852) and are set forth at 40 CFR 50.7.
The 2006 PM2.5 NAAQS, which became effective on December
18, 2006 (71 FR 61144), are set forth at 40 CFR 50.13. EPA has recently
determined that the Chicago and Evansville areas meet the 2006 24-hour
PM2.5 NAAQS, and has designated the areas as unclassifiable/
attainment for the 2006 24-hour NAAQS. 74 FR 58688, 58726-58729
(November 13, 2009). The status of the 2006 annual NAAQS designations
is described in the 2006 24-hour NAAQS designations notice. 74 FR
58690-58691. However, designations for the 2006 PM2.5 NAAQS
are independent of today's determinations that the Chicago and
Evansville areas are attaining the 1997 PM2.5 NAAQS.
[[Page 62248]]
If the Chicago and Evansville areas continue to attain the 1997
PM2.5 NAAQS, the requirements for Illinois and Indiana to
submit attainment demonstrations and associated RACM, RFP plans,
contingency measures, and any other planning SIPs related to attainment
of the 1997 PM2.5 NAAQS in these areas would remain
suspended.
V. When Are These Actions Effective?
EPA finds that there is good cause for these determinations to
become effective on the date of publication of these actions in the
Federal Register, because a delayed effective date is unnecessary due
to the nature of the actions. The expedited effective date for these
actions is authorized under both 5 U.S.C. 553(d)(1), which provides
that rule actions may become effective less than 30 days after
publication if the rule ``grants or recognizes an exemption or relieves
a restriction,'' and 5 U.S.C. 553(d)(3), which allows an effective date
less than 30 days after publication ``as otherwise provided by the
agency for good cause found and published with the rule.'' As noted
above, these determinations of attainment will result in a suspension
of the requirements for Chicago and Evansville to submit an attainment
demonstration, a RFP, section 172(c)(9) contingency measures, and any
other planning SIPs related to attainment of the 1997 PM2.5
NAAQS for so long as the area continues to attain the PM2.5
NAAQS. The suspension of these requirements is sufficient reason to
allow an expedited effective date of this rule under 5 U.S.C.
553(d)(1). In addition, the suspension of the obligations of Illinois
and Indiana to make submissions for these requirements provides good
cause to make this rule effective on the date of publication of this
action in the Federal Register, pursuant to 5 U.S.C. 553(d)(3). The
purpose of the 30-day waiting period prescribed in 5 U.S.C. 553(d) is
to give affected parties a reasonable time to adjust their behavior and
prepare before the final rule takes effect. Where, as here, the final
rule suspends requirements rather than imposing obligations, affected
parties, such as the Chicago and Evansville areas, do not need time to
adjust and prepare before the rule takes effect.
VI. Statutory and Executive Order Reviews
Under Executive Order 12866 (58 FR 51735, October 4, 1993), this
action is not a ``significant regulatory action'' and therefore is not
subject to review by the Office of Management and Budget. For this
reason, this action is not subject to Executive Order 13211, ``Actions
Concerning Regulations That Significantly Affect Energy Supply,
Distribution, or Use'' (66 FR 28355, May 22, 2001). This action makes a
determination based on air quality data and results in the suspension
of certain Federal requirements. Accordingly, the Administrator
certifies that this rule will not have a significant economic impact on
a substantial number of small entities under the Regulatory Flexibility
Act (5 U.S.C. 601 et seq.). Because this rule makes a determination
based on air quality data, and results in the suspension of certain
Federal requirements, it 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).
This rule also does not have tribal applications because it will
not have a substantial direct effect on one or more Indian tribes, on
the relationship between the Federal Government and Indian tribes, or
on the distribution of power and responsibilities between the Federal
Government and Indian tribes, as specified by Executive Order 13175 (65
FR 67249, November 9, 2000). This action also does not have Federalism
implications because it does 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 (64
FR 43255, August 10, 1999), because it merely makes a determination
based on air quality data and results in the suspension of certain
Federal requirements, and does not alter the relationship or the
distribution of power and responsibilities established in the CAA. This
rule also is not subject to Executive Order 13045 ``Protection of
Children from Environmental Health Risks'' (62 FR 19885, April 23,
1997) because it determines that air quality in the affected area is
meeting Federal standards.
The requirements of 12(d) of the National Technology Transfer and
Advancement Act of 1995 (15 U.S.C. 272 note) do not apply because it
would be inconsistent with applicable law for EPA, when determining the
attainment status of an area, to use voluntary consensus standards in
place of promulgated air quality standards and monitoring procedures to
otherwise satisfy the provisions of the CAA. This rule does not impose
an information collection burden under the provisions of the Paper
Reduction Act of 1995 (44 U.S.C. 3501 et seq.).
Under Executive Order 12898, EPA finds that this rule, pertaining
to the determinations of attainment of the fine particle standard for
the Chicago (Illinois and Indiana) and Evansville (Indiana) areas,
involves determinations of attainment based on air quality data and
will not have disproportionately high and adverse human health or
environmental effects on any communities in the area, including
minority and low-income communities.
In addition, this rule does not have tribal implications as
specified by Executive Order 13175 (65 FR 67249, November 9, 2000),
because there is no federally recognized Indian country located in the
states, 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 these actions and
other required information to the U.S. Senate, the U.S. House of
Representatives, and the Comptroller General of the United States prior
to publication of the rules in the Federal Register. A major rule
cannot take effect until 60 days after it is published in the Federal
Register. These actions are not ``major rules'' as defined by 5 U.S.C.
804(2).
Under section 307(b)(1) of the CAA, petitions for judicial review
of these actions must be filed in the United States Court of Appeals
for the appropriate circuit by January 26, 2010. Filing a petition for
reconsideration by the Administrator of these final rules does not
affect the finality of this action for the purposes of judicial review
nor does it extend the time within which a petition for judicial review
may be filed, and shall not postpone the effectiveness of such rule or
action. These actions may not be challenged later in proceedings to
enforce its requirements. (See section 307(b)(2).)
