ACTION: Proposed rule. AGENCY: The Environmental Protection Agency (EPA) is proposing to determine that the Saint Louis PM2.5 nonattainment area in Illinois and Missouri has attained the 1997 annual fine particle (PM2.5) National Ambient Air Quality Standard (NAAQS). This proposed determination of attainment is based upon complete, quality assured, quality controlled, and certified ambient air monitoring data, from the 2007–2009 monitoring period, which show that the Saint Louis area has monitored attainment of the 1997 annual PM2.5 NAAQS. EPA also evaluated incomplete data from this period from other monitors in the area, as well as preliminary data available to date for 2010. EPA believes these data support the determination that the area has attained the 1997 annual PM2.5 NAAQS. If this proposed determination is made final, the requirements for this area to submit an attainment demonstration, associated reasonably available control SUMMARY: PO 00000 Frm 00008 Fmt 4702 Sfmt 4702 measures (RACM) to include reasonably available control technology (RACT), a reasonable further progress plan, contingency measures, and other planning State Implementation Plans (SIPs) revisions related to attainment of the 1997 annual PM2.5 NAAQS shall be suspended for so long as the area continues to attain the 1997 annual PM2.5 NAAQS. EPA’s determination that this area has attained the 1997 annual PM2.5 NAAQS is not equivalent to redesignating the area to attainment. This action does not constitute a redesignation to attainment under section 107(d)(3) of the Clean Air Act (CAA) because the States of Missouri and Illinois have not yet submitted, and EPA has not yet approved, a maintenance plan for the area as required under that section and section 175A of the Act, nor has EPA promulgated a determination that the area has met other requirements for redesignation. The designation status of the area will remain nonattainment for the 1997 annual PM2.5 NAAQS until such time as EPA determines that this area meets the CAA requirements for redesignation to attainment.

SUPPLEMENTARY INFORMATION: Throughout this document whenever ‘‘we,’’ ‘‘us,’’ or ‘‘our’’ is used, we mean EPA. This supplementary information section is arranged as follows: I. What action is EPA proposing? II. What is the background of this action? III. What is EPA’s analysis of the relevant air quality data? IV. What are the effects of this action? V. Statutory and Executive Order Reviews I. What action is EPA proposing? The EPA is proposing to determine that the Saint Louis PM2.5 nonattainment area in the States of Missouri and Illinois has attained the 1997 annual PM2.5 NAAQS. The proposed determination is based upon complete, quality assured, quality controlled, and certified ambient air monitoring data from the 2007–2009 monitoring period which show that the Saint Louis area has monitored attainment of the 1997 annual PM2.5 NAAQS. Additional data from area monitors with incomplete data for this period (due for example to monitor closure) and also uncertified data available to date for 2010 support this determination. II. What is the background for this action? On July 18, 1997 (62 FR 36852), EPA established a health-based PM2.5 NAAQS at 15.0 micrograms per cubic meter (μg/m3) based on a 3-year average of annual mean PM2.5 concentrations, and a 24-hour standard of 65 μg/m3 based on a 3-year average of the 98th percentile of 24-hour concentrations. EPA established the standards based on significant evidence and numerous health studies demonstrating that serious health effects are associated with exposures to particulate matter. The process for designating areas following promulgation of a new or revised NAAQS is contained in section 107(d)(1) of the CAA, 42 U.S.C. 7406(d)(1). EPA and State air quality agencies generally initiated the monitoring process for the 1997 PM2.5 NAAQS in 1999, and implemented a full network of air quality monitors by January 2001. On January 5, 2005, in the Federal Register (70 FR 944), EPA published its air quality designations and classifications for the 1997 PM2.5 NAAQS based upon air quality monitoring data from those monitors for calendar years 2001–2003. EPA designated 39 areas as nonattainment for the 1997 annual PM2.5 NAAQS PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 12303 including the bi-state Saint Louis area (see 40 CFR part 81). These designations became effective on April 5, 2005. The Missouri portion of the Saint Louis PM2.5 nonattainment area includes the counties of Franklin, Jefferson, Saint Charles, Saint Louis, and the City of Saint Louis. The Illinois portion of the Saint Louis PM2.5 nonattainment area includes the counties of Madison, Monroe, Randolph (Baldwin Township only) and Saint Clair. See 40 CFR 81.314 (Illinois) and 40 CFR 81.326 (Missouri). In 2006, after thorough review of the 1997 PM standards, EPA retained the 1997 PM2.5 NAAQS at 15.0 μg/m3 based on a 3-year average of annual mean PM2.5 concentrations, and promulgated a 24-hour standard of 35 μg/m3 based on a 3-year average of the 98th percentile of 24-hour concentrations (the 2006 24hour standard). On November 13, 2009, EPA designated the Saint Louis area as attaining the 2006 24-hour standard (74 FR 58688). In that action, EPA also clarified the designations for the NAAQS promulgated in 1997, stating that the Saint Louis area remained designated nonattainment for the 1997 annual PM2.5 standard, but was attainment for the 1997 24-hour standard. Thus today’s action does not address attainment of either the 1997 or the 2006 24-hour standards. In response to legal challenges of the annual standard promulgated in 2006, the U.S. Court of Appeals for the District of Columbia Circuit (D.C. Circuit) remanded this standard to EPA for further consideration. See American Farm Bureau Federation and National Pork Producers Council, et al. v. EPA, 559 F.3d 512 (D.C. Cir. 2009). EPA notes, however, that since the 1997 and 2006 annual standards are essentially identical, attainment of the 1997 annual standard would also indicate attainment of the remanded 2006 annual standard. On April 25, 2007 (72 FR 20664), the EPA promulgated its PM2.5 implementation rule, codified at 40 CFR part 51, subpart Z, in which the EPA provided guidance for state and tribal plans to implement the 1997 annual PM2.5 NAAQS. This rule, at 40 CFR 51.1004(c), establishes certain regulatory consequences of a determination of attainment of the standard. III. What is EPA’s analysis of the relevant air quality data? Today’s rulemaking assesses whether the Saint Louis area is attaining the 1997 annual PM2.5 standard. Under EPA’s regulations at 40 CFR 50.7, the annual primary and secondary PM2.5 standards are met when the annual arithmetic mean concentration, as E:\FR\FM\07MRP1.SGM 07MRP1 12304 Federal Register / Vol. 76, No. 44 / Monday, March 7, 2011 / Proposed Rules determined in accordance with 40 CFR part 50, Appendix N, is less than or equal to 15.0 μg/m3 at all relevant monitoring sites in the area. The EPA has reviewed the ambient air quality monitoring data in the Saint Louis area for PM2.5, consistent with the requirements contained at 40 CFR part 50. EPA’s review focused on data recorded in the EPA Air Quality System (AQS) database for the Saint Louis PM2.5 nonattainment area from 2007 to 2009, and supplementally considered data recorded before and after that period. Table 1 shows the 2007 to 2009 design values (i.e., the 3-year average of annual mean PM2.5 concentrations) for the 1997 annual PM2.5 NAAQs for the Saint Louis PM2.5 nonattainment area monitors with complete data for that period. All data values are expressed in micrograms per meter cubed.

As Table 1 shows, there were eight monitoring sites with complete data for 2007 to 2009. Data are considered to be sufficient for comparison to the NAAQS if three consecutive complete years of data exist. A complete year of air quality data comprises four calendar quarters, with each quarter containing data from at least 75% of the scheduled sampling days. These eight monitoring sites with complete data provide an adequate basis for EPA to determine whether the area has attained the NAAQS. See 40 CFR part 58, Appendix D for network design criteria.

The EPA concludes that the Saint Louis area has attained the 1997 annual PM2.5 NAAQS based on its evaluation of complete quality assured data from the relevant monitoring sites for the 2007– 2009 monitoring period. Incomplete data from additional monitoring sites in the area also support EPA’s determination that area attains the 1997 annual PM2.5 NAAQS. A number of additional monitors have recorded data that are not considered as complete for the three-year 2007–2009 monitoring period. Pertinent data from these sites are shown in Table 2. As 14.1 12.5 12.5 11.4 13.3 12.5 12.8 12.7 shown in this table, although several of these sites shut down recently, the most recent three years of complete data at all of these sites showed the area to be attaining the standard, a conclusion that is supported by the data that are available, though not complete for 2007 to 2009. Table 2 includes sites that started operation only recently; these sites did not have a complete set of data for 2007–2009, but the available data from that period add support to the conclusion that the area is attaining the standard.

Data handling conventions and computations necessary for determining whether areas have met the PM2.5 NAAQS, including requirements for data completeness, are listed in Appendix N of 40 CFR part 50. The use of less than complete data is subject to the approval of the EPA, which may consider factors such as monitoring site closures/moves, monitoring diligence and nearby concentrations in determining whether to use such data as set forth at 40 CFR part 50, Appendix N VerDate Mar<15>2010 13:53 Mar 04, 2011 Jkt 223001 Average value 2007– 2009 Monitor 17–119–0024 29–099–0012 29–099–0019 29–183–1002 29–189–0015 29–189–2003 29–189–3001 29–510–0086 29–510–0087 13.6 12.9 11.1 12.7 12.6 12.1 11.1 13.1 12.8 section 4.1(c).

E:\FR\FM\07MRP1.SGM 07MRP1 Federal Register / Vol. 76, No. 44 / Monday, March 7, 2011 / Proposed Rules The EPA also has considered additional monitoring data for 2010 that have been submitted by the states and are in EPA’s AQS. Data for the entire 2010 calendar year are not yet certified, so EPA cannot consider these data yet as it evaluates the annual average concentrations. Nevertheless, EPA examined 2010 data available to date as an indication of whether the area continues to attain the standard. EPA believes that these data support the determination that the Saint Louis area continues to attain the PM2.5 annual NAAQS. The EPA’s review of these data (monitoring data from the 2007–2009 monitoring period and preliminary 2010 data available to date) supports EPA’s determination that the Saint Louis PM2.5 nonattainment area has met and continues to meet the 1997 annual PM2.5 NAAQS. EPA is soliciting comment on the issues discussed in this document. These comments will be considered before EPA takes final action. WReier-Aviles on DSKGBLS3C1PROD with PROPOSALS IV. What are the effects of this action? If this proposed determination is made final, under the provisions of the PM2.5 Implementation Rule (40 CFR 51.1004(c)) the requirements for the Saint Louis PM2.5 nonattainment area to submit attainment demonstration, RACM (including RACT), a reasonable further progress plan, contingency measures, and other planning SIPs revisions related to attainment of the 1997 annual PM2.5 NAAQS shall be suspended for so long as the area continues to attain the 1997 annual PM2.5 NAAQS. As discussed further, the proposed determination of attainment for the Saint Louis PM2.5 nonattainment area would, if finalized: (1) Suspend the States’ obligation for Missouri and Illinois to submit the requirements listed above; (2) continue such suspension until such time, if any, that EPA subsequently determines that any monitor in the area has violated the 1997 annual PM2.5 NAAQS; and (3) be separate from, and not influence or otherwise affect, any future designation determination or requirements for the Saint Louis PM2.5 nonattainment areas based on the 2006 PM2.5 NAAQS or future PM2.5 NAAQ revision. If this rulemaking is finalized and EPA subsequently determines, after notice-and-comment rulemaking in the Federal Register, that the area has violated the 1997 annual PM2.5 NAAQS, the basis for the suspension of the specific requirements, set forth at 40 CFR section 51.1004(c), would no longer exist, and the States of Missouri and VerDate Mar<15>2010 13:53 Mar 04, 2011 Jkt 223001 12305 Illinois would thereafter have to address the pertinent requirements. This proposed approval is limited to a determination that the air quality data show that the Saint Louis PM2.5 nonattainment area has monitored attainment of the 1997 annual PM2.5 NAAQS; it is not equivalent to the redesignation of the Saint Louis PM2.5 nonattainment area to attainment of the 1997 annual PM2.5 NAAQS. This proposed action, if finalized, would not constitute a redesignation to attainment under section 107(d)(3) of the Clean Air Act (CAA) because the EPA would not have yet approved a maintenance plan for the area as required under CAA section 175A, nor a determination that the Saint Louis PM2.5 nonattainment area has met the other requirements for redesignation under the CAA. The designation status of the Missouri and Illinois portions of the Saint Louis PM2.5 nonattainment area will remain nonattainment for the 1997 annual PM2.5 NAAQS until such time as the EPA takes final rulemaking action to determine that such portions meet the CAA requirements for redesignation to attainment. • 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).

Approval and Promulgation of Air Quality Implementation Plans; 
Illinois; Missouri; Saint Louis Nonattainment Area; Determination of 
Attainment of the Fine Particle Standard

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
determine that the Saint Louis PM2.5 nonattainment area in 
Illinois and Missouri has attained the 1997 annual fine particle 
(PM2.5) National Ambient Air Quality Standard (NAAQS). This 
proposed determination of attainment is based upon complete, quality 
assured, quality controlled, and certified ambient air monitoring data, 
from the 2007-2009 monitoring period, which show that the Saint Louis 
area has monitored attainment of the 1997 annual PM2.5 
NAAQS. EPA also evaluated incomplete data from this period from other 
monitors in the area, as well as preliminary data available to date for 
2010. EPA believes these data support the determination that the area 
has attained the 1997 annual PM2.5 NAAQS. If this proposed 
determination is made final, the requirements for this area to submit 
an attainment demonstration, associated reasonably available control 
measures (RACM) to include reasonably available control technology 
(RACT), a reasonable further progress plan, contingency measures, and 
other planning State Implementation Plans (SIPs) revisions related to 
attainment of the 1997 annual PM2.5 NAAQS shall be suspended 
for so long as the area continues to attain the 1997 annual 
PM2.5 NAAQS.
    EPA's determination that this area has attained the 1997 annual 
PM2.5 NAAQS is not equivalent to redesignating the area to 
attainment. This action does not constitute a redesignation to 
attainment under section 107(d)(3) of the Clean Air Act (CAA) because 
the States of Missouri and Illinois have not yet submitted, and EPA has 
not yet approved, a maintenance plan for the area as required under 
that section and section 175A of the Act, nor has EPA promulgated a 
determination that the area has met other requirements for 
redesignation. The designation status of the area will remain 
nonattainment for the 1997 annual PM2.5 NAAQS until such 
time as EPA determines that this area meets the CAA requirements for 
redesignation to attainment.

SUPPLEMENTARY INFORMATION: Throughout this document whenever ``we,''

section is arranged as follows:

I. What action is EPA proposing?
II. What is the background of this action?
III. What is EPA's analysis of the relevant air quality data?
IV. What are the effects of this action?
V. Statutory and Executive Order Reviews

I. What action is EPA proposing?

    The EPA is proposing to determine that the Saint Louis 
PM2.5 nonattainment area in the States of Missouri and 
Illinois has attained the 1997 annual PM2.5 NAAQS. The 
proposed determination is based upon complete, quality assured, quality 
controlled, and certified ambient air monitoring data from the 2007-
2009 monitoring period which show that the Saint Louis area has 
monitored attainment of the 1997 annual PM2.5 NAAQS. 
Additional data from area monitors with incomplete data for this period 
(due for example to monitor closure) and also uncertified data 
available to date for 2010 support this determination.

II. What is the background for this action?

    On July 18, 1997 (62 FR 36852), EPA established a health-based 
PM2.5 NAAQS at 15.0 micrograms per cubic meter ([mu]g/m\3\) 
based on a 3-year average of annual mean PM2.5 
concentrations, and a 24-hour standard of 65 [mu]g/m\3\ based on a 3-
year average of the 98th percentile of 24-hour concentrations.
    EPA established the standards based on significant evidence and 
numerous health studies demonstrating that serious health effects are 
associated with exposures to particulate matter. The process for 
designating areas following promulgation of a new or revised NAAQS is 
contained in section 107(d)(1) of the CAA, 42 U.S.C. 7406(d)(1). EPA 
and State air quality agencies generally initiated the monitoring 
process for the 1997 PM2.5 NAAQS in 1999, and implemented a 
full network of air quality monitors by January 2001.
    On January 5, 2005, in the Federal Register (70 FR 944), EPA 
published its air quality designations and classifications for the 1997 
PM2.5 NAAQS based upon air quality monitoring data from 
those monitors for calendar years 2001-2003. EPA designated 39 areas as 
nonattainment for the 1997 annual PM2.5 NAAQS including the 
bi-state Saint Louis area (see 40 CFR part 81). These designations 
became effective on April 5, 2005. The Missouri portion of the Saint 
Louis PM2.5 nonattainment area includes the counties of 
Franklin, Jefferson, Saint Charles, Saint Louis, and the City of Saint 
Louis. The Illinois portion of the Saint Louis PM2.5 
nonattainment area includes the counties of Madison, Monroe, Randolph 
(Baldwin Township only) and Saint Clair. See 40 CFR 81.314 (Illinois) 
and 40 CFR 81.326 (Missouri).
    In 2006, after thorough review of the 1997 PM standards, EPA 
retained the 1997 PM2.5 NAAQS at 15.0 [mu]g/m\3\ based on a 
3-year average of annual mean PM2.5 concentrations, and 
promulgated a 24-hour standard of 35 [mu]g/m\3\ based on a 3-year 
average of the 98th percentile of 24-hour concentrations (the 2006 24-
hour standard). On November 13, 2009, EPA designated the Saint Louis 
area as attaining the 2006 24-hour standard (74 FR 58688). In that 
action, EPA also clarified the designations for the NAAQS promulgated 
in 1997, stating that the Saint Louis area remained designated 
nonattainment for the 1997 annual PM2.5 standard, but was 
attainment for the 1997 24-hour standard. Thus today's action does not 
address attainment of either the 1997 or the 2006 24-hour standards.
    In response to legal challenges of the annual standard promulgated 
in 2006, the U.S. Court of Appeals for the District of Columbia Circuit 
(D.C. Circuit) remanded this standard to EPA for further consideration. 
See American Farm Bureau Federation and National Pork Producers 
Council, et al. v. EPA, 559 F.3d 512 (D.C. Cir. 2009). EPA notes, 
however, that since the 1997 and 2006 annual standards are essentially 
identical, attainment of the 1997 annual standard would also indicate 
attainment of the remanded 2006 annual standard.
    On April 25, 2007 (72 FR 20664), the EPA promulgated its 
PM2.5 implementation rule, codified at 40 CFR part 51, 
subpart Z, in which the EPA provided guidance for state and tribal 
plans to implement the 1997 annual PM2.5 NAAQS. This rule, 
at 40 CFR 51.1004(c), establishes certain regulatory consequences of a 
determination of attainment of the standard.

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

    Today's rulemaking assesses whether the Saint Louis area is 
attaining the 1997 annual PM2.5 standard. Under EPA's 
regulations at 40 CFR 50.7, the annual primary and secondary 
PM2.5 standards are met when the annual arithmetic mean 
concentration, as

[[Page 12304]]

determined in accordance with 40 CFR part 50, Appendix N, is less than 
or equal to 15.0 [mu]g/m\3\ at all relevant monitoring sites in the 
area.
    The EPA has reviewed the ambient air quality monitoring data in the 
Saint Louis area for PM2.5, consistent with the requirements 
contained at 40 CFR part 50. EPA's review focused on data recorded in 
the EPA Air Quality System (AQS) database for the Saint Louis 
PM2.5 nonattainment area from 2007 to 2009, and 
supplementally considered data recorded before and after that period.
    Table 1 shows the 2007 to 2009 design values (i.e., the 3-year 
average of annual mean PM2.5 concentrations) for the 1997 
annual PM2.5 NAAQs for the Saint Louis PM2.5 
nonattainment area monitors with complete data for that period. All 
data values are expressed in micrograms per meter cubed.

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

    As Table 1 shows, there were eight monitoring sites with complete 
data for 2007 to 2009. Data are considered to be sufficient for 
comparison to the NAAQS if three consecutive complete years of data 
exist. A complete year of air quality data comprises four calendar 
quarters, with each quarter containing data from at least 75% of the 
scheduled sampling days. These eight monitoring sites with complete 
data provide an adequate basis for EPA to determine whether the area 
has attained the NAAQS. See 40 CFR part 58, Appendix D for network 
design criteria.
    The EPA concludes that the Saint Louis area has attained the 1997 
annual PM2.5 NAAQS based on its evaluation of complete 
quality assured data from the relevant monitoring sites for the 2007-
2009 monitoring period.
    Incomplete data from additional monitoring sites in the area also 
support EPA's determination that area attains the 1997 annual 
PM2.5 NAAQS. A number of additional monitors have recorded 
data that are not considered as complete for the three-year 2007-2009 
monitoring period. Pertinent data from these sites are shown in Table 
2. As shown in this table, although several of these sites shut down 
recently, the most recent three years of complete data at all of these 
sites showed the area to be attaining the standard, a conclusion that 
is supported by the data that are available, though not complete for 
2007 to 2009. Table 2 includes sites that started operation only 
recently; these sites did not have a complete set of data for 2007-
2009, but the available data from that period add support to the 
conclusion that the area is attaining the standard.

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

    Data handling conventions and computations necessary for 
determining whether areas have met the PM2.5 NAAQS, 
including requirements for data completeness, are listed in Appendix N 
of 40 CFR part 50. The use of less than complete data is subject to the 
approval of the EPA, which may consider factors such as monitoring site 
closures/moves, monitoring diligence and nearby concentrations in 
determining whether to use such data as set forth at 40 CFR part 50, 
Appendix N section 4.1(c). The monitors listed in Table 2 do not have 
complete data for the 2007-2009 monitoring period. However, the 
historical certified data recorded at the monitors that were 
discontinued during this period and recent certified data recorded at 
monitors that started operation during the period provide additional 
support for EPA's proposed determination that the Saint Louis area has 
attained the 1997 annual PM2.5 NAAQS. EPA is also approving 
the use of these data for consideration in this determination because 
it finds that Missouri and Illinois have exercised diligence in 
monitoring in the Saint Louis area, and have worked cooperatively with 
EPA in evaluating and seeking approval for monitor closures and moves. 
A discussion of each of the monitors with incomplete data for the 2007-
2009 period is available in a technical support document, which is part 
of the docket of this proposed rulemaking.

[[Page 12305]]

    The EPA also has considered additional monitoring data for 2010 
that have been submitted by the states and are in EPA's AQS. Data for 
the entire 2010 calendar year are not yet certified, so EPA cannot 
consider these data yet as it evaluates the annual average 
concentrations. Nevertheless, EPA examined 2010 data available to date 
as an indication of whether the area continues to attain the standard. 
EPA believes that these data support the determination that the Saint 
Louis area continues to attain the PM2.5 annual NAAQS.
    The EPA's review of these data (monitoring data from the 2007-2009 
monitoring period and preliminary 2010 data available to date) supports 
EPA's determination that the Saint Louis PM2.5 nonattainment 
area has met and continues to meet the 1997 annual PM2.5 
NAAQS. EPA is soliciting comment on the issues discussed in this 
document. These comments will be considered before EPA takes final 
action.

IV. What are the effects of this action?

    If this proposed determination is made final, under the provisions 
of the PM2.5 Implementation Rule (40 CFR 51.1004(c)) the 
requirements for the Saint Louis PM2.5 nonattainment area to 
submit attainment demonstration, RACM (including RACT), a reasonable 
further progress plan, contingency measures, and other planning SIPs 
revisions related to attainment of the 1997 annual PM2.5 
NAAQS shall be suspended for so long as the area continues to attain 
the 1997 annual PM2.5 NAAQS.
    As discussed further, the proposed determination of attainment for 
the Saint Louis PM2.5 nonattainment area would, if 
finalized: (1) Suspend the States' obligation for Missouri and Illinois 
to submit the requirements listed above; (2) continue such suspension 
until such time, if any, that EPA subsequently determines that any 
monitor in the area has violated the 1997 annual PM2.5 
NAAQS; and (3) be separate from, and not influence or otherwise affect, 
any future designation determination or requirements for the Saint 
Louis PM2.5 nonattainment areas based on the 2006 
PM2.5 NAAQS or future PM2.5 NAAQ revision.
    If this rulemaking is finalized and EPA subsequently determines, 
after notice-and-comment rulemaking in the Federal Register, that the 
area has violated the 1997 annual PM2.5 NAAQS, the basis for 
the suspension of the specific requirements, set forth at 40 CFR 
section 51.1004(c), would no longer exist, and the States of Missouri 
and Illinois would thereafter have to address the pertinent 
requirements.
    This proposed approval is limited to a determination that the air 
quality data show that the Saint Louis PM2.5 nonattainment 
area has monitored attainment of the 1997 annual PM2.5 
NAAQS; it is not equivalent to the redesignation of the Saint Louis 
PM2.5 nonattainment area to attainment of the 1997 annual 
PM2.5 NAAQS. This proposed action, if finalized, would not 
constitute a redesignation to attainment under section 107(d)(3) of the 
Clean Air Act (CAA) because the EPA would not have yet approved a 
maintenance plan for the area as required under CAA section 175A, nor a 
determination that the Saint Louis PM2.5 nonattainment area 
has met the other requirements for redesignation under the CAA. The 
designation status of the Missouri and Illinois portions of the Saint 
Louis PM2.5 nonattainment area will remain nonattainment for 
the 1997 annual PM2.5 NAAQS until such time as the EPA takes 
final rulemaking action to determine that such portions meet the CAA 
requirements for redesignation to attainment.

V. Statutory and Executive Order Reviews

    This action proposes to make a determination based on air quality 
data and would, if finalized, result in the suspension of certain 
Federal requirements and would not impose any additional 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 .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 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
