ACTION: Proposed rule. AGENCY: The Environmental Protection Agency (EPA) is proposing to approve a request from the Missouri Department of Natural Resources (MoDNR) to redesignate the Missouri portion of the SUMMARY: VerDate Sep<11>2014 16:42 May 15, 2019 Jkt 247001 St. Louis-St. Charles-Farmington, MO-IL fine particulate matter (PM2.5) unclassifiable area (‘‘St. Louis area’’ or ‘‘area’’) to unclassifiable/attainment for the 2012 annual fine particulate matter (PM2.5) National Ambient Air Quality Standard (NAAQS). The Missouri portion of the St. Louis area comprises of the City of St. Louis and the counties of Franklin, Jefferson, St. Charles, and St. Louis. The EPA now has sufficient data to determine that the St. Louis area is in attainment of the 2012 PM2.5 NAAQS. Therefore, EPA is proposing to approve the state’s December 11, 2018 request, and redesignate the area to unclassifiable/attainment for the 2012 PM2.5 NAAQS based upon valid, quality-assured, and certified ambient air monitoring data showing that the PM2.5 monitors in the area are in compliance with the 2012 PM2.5 NAAQS. The EPA will address the Illinois portion of the St. Louis area in a separate rulemaking action. Comments must be received on or before June 17, 2019. DATES: 22101 I.

The Clean Air Act (CAA) establishes a process for air quality management through the establishment and implementation of the NAAQS. Upon promulgation of a new or revised NAAQS, section 107(d)(1)of the CAA requires EPA to designate areas as attainment, nonattainment, or unclassifiable. On December 14, 2012, the EPA promulgated a revised primary annual PM2.5 NAAQS to provide increased protection of public health and welfare from fine particle pollution (78 FR 3086, January 15, 2013). In that action, the EPA revised the primary annual PM2.5 standard, strengthening it from 15.0 micrograms per cubic meter (mg/m3) to 12.0 (mg/m3), which is attained when the three-year average of the annual arithmetic means does not exceed 12.0 (mg/m3).

E:\FR\FM\16MYP1.SGM 16MYP1 22102 Federal Register / Vol. 84, No. 95 / Thursday, May 16, 2019 / Proposed Rules established the standard 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. On December 18, 2014, the EPA designated the majority of areas across the country as nonattainment, unclassifiable/ attainment, or unclassifiable 1 for the 2012 PM2.5 NAAQS based upon air quality monitoring data from monitors for calendar years 2011–2013. See 80 FR 2206 (January 15, 2015). The EPA initially designated the bistate St. Louis area as unclassifiable based on ambient air quality data from 2011–2013. During that time period, the EPA identified data completeness issues with the ambient PM2.5 monitoring data in the state of Illinois. Although all monitors in Missouri were attaining the standard at the time of the initial designations, the lack of complete monitoring data in Illinois prevented EPA from being able to determine whether violations of the standard were occurring in the Illinois portion of the St.Louis area or whether emission sources in Missouri were contributing to any violations in Illinois. Therefore, the EPA designated the entire St. Louis MOIL area as unclassifiable for the 2012 PM2.5 NAAQS. IV. What are the criteria for redesignating an area from unclassifiable to unclassifiable/ attainment? Section 107(d)(3) of the CAA provides the framework for changing the area designations for any NAAQS pollutants. Section 107(d)(3)(A) provides that the Administrator may notify the Governor of any state that the designation of an area should be revised ‘‘on the basis of air quality data, planning and control considerations, or any other air qualityrelated considerations the Administrator deems appropriate.’’ The CAA further provides in section 107(d)(3)(D) that even if the Administrator has not notified a state Governor that a designation should be revised, the Governor of any state may, on the Governor’s own motion, submit a request to revise the designation of any area, and the Administrator must approve or deny the request. When approving or denying a request to redesignate an area, EPA bases its decision on the air quality data for the area as well as the considerations provided under section 107(d)(3)(A).2 In keeping with section 107(d)(1)(A), areas that are redesignated to unclassifiable/ attainment must meet the requirements for attainment areas and thus must meet the relevant NAAQS. In addition, the area must not contribute to ambient air quality in a nearby area that does not meet the NAAQS. The relevant monitoring data must be collected and quality-assured in accordance with 40 CFR part 58 and recorded in the EPA Air Quality System (AQS) database. The designated monitors generally should have remained at the same location for the duration of the monitoring period upon which the redesignation request is based.3 V. What is the EPA’s rationale for proposing to redesignate the area? To redesignate the area from unclassifiable to unclassifiable/ attainment for the 2012 primary annual PM2.5 NAAQS, the three-year average of the annual arimethic means does not exceed 12.0 (mg/m3) at all monitoring sites in the area over the full three-year period, as determined in accordance with 40 CFR 50.18 and appendix N of part 50. The EPA reviewed PM2.5 monitoring data from the monitors in the St. Louis area for the 2012 PM2.5 NAAQS for the three-year period from 2015–2017. As summarized in table 1, the design values for the monitors in the area for the 2015–2017 are below the 2012 PM2.5 NAAQS. These data have been quality-assured, certified, and recorded in AQS by Missouri and Illinois, and the monitoring location has not changed during the monitoring period.

VI. Proposed Action The EPA is proposing to approve the MoDNR’s December 11, 2018, request to redesignate the Missouri’s portion of the St. Louis area from unclassifiable to 1 For the initial PM area designations in 2014 (for the 2012 annual PM2.5 NAAQS), EPA used a designation category of ‘‘unclassifiable/attainment’’ for areas that had monitors showing attainment of the standard and were not contributing to nearby violations and for areas that did not have monitors but for which EPA had reason to believe were likely attaining the standard and not contributing to nearby violations. EPA used the category ‘‘unclassifiable’’ for areas in which EPA could not determine, based upon available information, whether or not the NAAQS was being met and/or EPA had not determined the area to be contributing to nearby violations. EPA reserves the ‘‘attainment’’ category for when EPA redesignates a nonattainment area that has attained the relevant NAAQS and has an approved maintenance plan. 2 While CAA section 107(d)(3)(E) also lists specific requirements for redesignations, those requirements only apply to redesignations of nonattainment areas to attainment and therefore are not applicable in the context of a redesignation of an area from unclassifiable to unclassifiable/ attainment. 3 See ‘‘Procedures for Processing Requests to Redesignate Areas to Attainment’’, Memorandum from John Calcagni, Director, Air Quality Management Division, September 4, 1992 (the ‘‘Calcagni Memorandum’’).

If finalized, approval of the redesignation request would change the legal designation, found at 40 CFR part 81, of the City of St. Louis and the counties of Franklin, Jefferson, St. Charles, and St. Louis from unclassifiable to unclassifiable/attainment for the 2012 primary annual PM2.5 NAAQS. VII. Statutory and Executive Order Reviews Under the CAA, a redesignation of an area to unclassifiable/attainment is an action that affects the status of a geographical area and does not impose any additional regulatory requirements on sources beyond those imposed by state law. A redesignation to unclassifiable/attainment does not create any new requirements. Accordingly, this action merely proposes to redesignate an area to unclassifiable/attainment and does not impose 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 Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011); • Is not an Executive Order 13771 (82 FR 9339, February 2, 2017) regulatory action because SIP approvals are exempted under Executive Order 12866. • 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 the National Technology Transfer and Advancement Act (NTTA) because this rulemaking does not involve technical standards; 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). This proposed action is not approved to apply on any Indian reservation land or in any other area where EPA or an Indian tribe has demonstrated that a tribe has jurisdiction. In those areas of Indian country, the proposed rule does not have tribal implications and will not impose substantial direct costs on tribal governments or preempt tribal law as specified by Executive Order 13175 (65 FR 67249, November 9, 2000).

Approval of Missouri Air Quality Implementation Plans; 
Redesignation of the Missouri Portion of the St. Louis-St. Charles-
Farmington, MO-IL 2012 PM2.5 Unclassifiable Area

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve a request from the Missouri Department of Natural Resources 
(MoDNR) to redesignate the Missouri portion of the St. Louis-St. 
Charles-Farmington, MO-IL fine particulate matter (PM2.5) 
unclassifiable area (``St. Louis area'' or ``area'') to unclassifiable/
attainment for the 2012 annual fine particulate matter 
(PM2.5) National Ambient Air Quality Standard (NAAQS). The 
Missouri portion of the St. Louis area comprises of the City of St. 
Louis and the counties of Franklin, Jefferson, St. Charles, and St. 
Louis. The EPA now has sufficient data to determine that the St. Louis 
area is in attainment of the 2012 PM2.5 NAAQS. Therefore, 
EPA is proposing to approve the state's December 11, 2018 request, and 
redesignate the area to unclassifiable/attainment for the 2012 
PM2.5 NAAQS based upon valid, quality-assured, and certified 
ambient air monitoring data showing that the PM2.5 monitors 
in the area are in compliance with the 2012 PM2.5 NAAQS. The 
EPA will address the Illinois portion of the St. Louis area in a 
separate rulemaking action.

II. What is being addressed in this document?

    The EPA is proposing to approve MoDNR's request to change the 
designation of the Missouri portion of the St. Louis area from 
unclassifiable to unclassifiable/attainment for the 2012 
PM2.5 NAAQS, based on quality-assured and certified 
monitoring data for 2015-2017, and proposing to approve that the 
Missouri portion of the St. Louis area has met the requirements for 
redesignation under section 107(d)(3)(E) of the CAA.

III. Background Information

    The Clean Air Act (CAA) establishes a process for air quality 
management through the establishment and implementation of the NAAQS. 
Upon promulgation of a new or revised NAAQS, section 107(d)(1)of the 
CAA requires EPA to designate areas as attainment, nonattainment, or 
unclassifiable. On December 14, 2012, the EPA promulgated a revised 
primary annual PM2.5 NAAQS to provide increased protection 
of public health and welfare from fine particle pollution (78 FR 3086, 
January 15, 2013). In that action, the EPA revised the primary annual 
PM2.5 standard, strengthening it from 15.0 micrograms per 
cubic meter ([mu]g/m\3\) to 12.0 ([mu]g/m\3\), which is attained when 
the three-year average of the annual arithmetic means does not exceed 
12.0 ([mu]g/m\3\). The EPA

[[Page 22102]]

established the standard 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. On 
December 18, 2014, the EPA designated the majority of areas across the 
country as nonattainment, unclassifiable/attainment, or unclassifiable 
\1\ for the 2012 PM2.5 NAAQS based upon air quality 
monitoring data from monitors for calendar years 2011-2013. See 80 FR 
2206 (January 15, 2015).
---------------------------------------------------------------------------

    \1\ For the initial PM area designations in 2014 (for the 2012 
annual PM2.5 NAAQS), EPA used a designation category of 
``unclassifiable/attainment'' for areas that had monitors showing 
attainment of the standard and were not contributing to nearby 
violations and for areas that did not have monitors but for which 
EPA had reason to believe were likely attaining the standard and not 
contributing to nearby violations. EPA used the category 
``unclassifiable'' for areas in which EPA could not determine, based 
upon available information, whether or not the NAAQS was being met 
and/or EPA had not determined the area to be contributing to nearby 
violations. EPA reserves the ``attainment'' category for when EPA 
redesignates a nonattainment area that has attained the relevant 
NAAQS and has an approved maintenance plan.
---------------------------------------------------------------------------

    The EPA initially designated the bi-state St. Louis area as 
unclassifiable based on ambient air quality data from 2011-2013. During 
that time period, the EPA identified data completeness issues with the 
ambient PM2.5 monitoring data in the state of Illinois. 
Although all monitors in Missouri were attaining the standard at the 
time of the initial designations, the lack of complete monitoring data 
in Illinois prevented EPA from being able to determine whether 
violations of the standard were occurring in the Illinois portion of 
the St.Louis area or whether emission sources in Missouri were 
contributing to any violations in Illinois. Therefore, the EPA 
designated the entire St. Louis MO-IL area as unclassifiable for the 
2012 PM2.5 NAAQS.

IV. What are the criteria for redesignating an area from unclassifiable 
to unclassifiable/attainment?

    Section 107(d)(3) of the CAA provides the framework for changing 
the area designations for any NAAQS pollutants. Section 107(d)(3)(A) 
provides that the Administrator may notify the Governor of any state 
that the designation of an area should be revised ``on the basis of air 
quality data, planning and control considerations, or any other air 
quality-related considerations the Administrator deems appropriate.'' 
The CAA further provides in section 107(d)(3)(D) that even if the 
Administrator has not notified a state Governor that a designation 
should be revised, the Governor of any state may, on the Governor's own 
motion, submit a request to revise the designation of any area, and the 
Administrator must approve or deny the request.
    When approving or denying a request to redesignate an area, EPA 
bases its decision on the air quality data for the area as well as the 
considerations provided under section 107(d)(3)(A).\2\ In keeping with 
section 107(d)(1)(A), areas that are redesignated to unclassifiable/
attainment must meet the requirements for attainment areas and thus 
must meet the relevant NAAQS. In addition, the area must not contribute 
to ambient air quality in a nearby area that does not meet the NAAQS. 
The relevant monitoring data must be collected and quality-assured in 
accordance with 40 CFR part 58 and recorded in the EPA Air Quality 
System (AQS) database. The designated monitors generally should have 
remained at the same location for the duration of the monitoring period 
upon which the redesignation request is based.\3\
---------------------------------------------------------------------------

    \2\ While CAA section 107(d)(3)(E) also lists specific 
requirements for redesignations, those requirements only apply to 
redesignations of nonattainment areas to attainment and therefore 
are not applicable in the context of a redesignation of an area from 
unclassifiable to unclassifiable/attainment.
    \3\ See ``Procedures for Processing Requests to Redesignate 
Areas to Attainment'', Memorandum from John Calcagni, Director, Air 
Quality Management Division, September 4, 1992 (the ``Calcagni 
Memorandum'').
---------------------------------------------------------------------------

V. What is the EPA's rationale for proposing to redesignate the area?

    To redesignate the area from unclassifiable to unclassifiable/
attainment for the 2012 primary annual PM2.5 NAAQS, the 
three-year average of the annual arimethic means does not exceed 12.0 
([mu]g/m\3\) at all monitoring sites in the area over the full three-
year period, as determined in accordance with 40 CFR 50.18 and appendix 
N of part 50. The EPA reviewed PM2.5 monitoring data from 
the monitors in the St. Louis area for the 2012 PM2.5 NAAQS 
for the three-year period from 2015-2017. As summarized in table 1, the 
design values for the monitors in the area for the 2015-2017 are below 
the 2012 PM2.5 NAAQS. These data have been quality-assured, 
certified, and recorded in AQS by Missouri and Illinois, and the 
monitoring location has not changed during the monitoring period.

    The EPA is proposing to redesignate the Missouri portion of the St. 
Louis area from unclassifiable to unclassifiable/attainment because the 
three-year design value meets the 2012 primary annual PM2.5 
NAAQS.

VI. Proposed Action

    The EPA is proposing to approve the MoDNR's December 11, 2018, 
request to redesignate the Missouri's portion of the St. Louis area 
from unclassifiable to

[[Page 22103]]

unclassifiable/attainment for the 2012 primary annual PM2.5 
NAAQS. If finalized, approval of the redesignation request would change 
the legal designation, found at 40 CFR part 81, of the City of St. 
Louis and the counties of Franklin, Jefferson, St. Charles, and St. 
Louis from unclassifiable to unclassifiable/attainment for the 2012 
primary annual PM2.5 NAAQS.

VII. Statutory and Executive Order Reviews

    Under the CAA, a redesignation of an area to unclassifiable/
attainment is an action that affects the status of a geographical area 
and does not impose any additional regulatory requirements on sources 
beyond those imposed by state law. A redesignation to unclassifiable/
attainment does not create any new requirements. Accordingly, this 
action merely proposes to redesignate an area to unclassifiable/
attainment and does not impose 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 Orders 12866 (58 
FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
     Is not an Executive Order 13771 (82 FR 9339, February 2, 
2017) regulatory action because SIP approvals are exempted under 
Executive Order 12866.
     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 the National Technology 
Transfer and Advancement Act (NTTA) because this rulemaking does not 
involve technical standards; 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).
    This proposed action is not approved to apply on any Indian 
reservation land or in any other area where EPA or an Indian tribe has 
demonstrated that a tribe has jurisdiction. In those areas of Indian 
country, the proposed rule does not have tribal implications and will 
not impose substantial direct costs on tribal governments or preempt 
tribal law as specified by Executive Order 13175 (65 FR 67249, November 
9, 2000).
