Attainment Date Extensions for the Logan, Utah-Idaho 24-Hour Fine 
Particulate Matter Nonattainment Area

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
grant two, one-year extensions to the Moderate attainment date for the 
2006 24-hour fine particulate matter (PM2.5) Logan, Utah 
(UT)-Idaho (ID) nonattainment area. This action is based on the EPA's 
evaluation of air quality monitoring data and extension requests 
submitted by the State of Utah on May 2, 2017, and the State of Idaho 
on December 15, 2015, February 26, 2016, and April 25, 2017. The EPA is 
proposing to grant a one-year extension of the Moderate attainment date 
from December 31, 2015 to December 31, 2016, and is proposing to grant 
a second one-year extension of the Moderate attainment date from 
December 31, 2016 to December 31, 2017, in accordance with section 
188(d) of the Clean Air Act (CAA).

II. Background

A. Designation and Classification of PM2.5 Nonattainment 
Areas

    On October 17, 2006 (71 FR 61144), the EPA revised the level of the 
24-hour PM2.5 National Ambient Air Quality Standard (NAAQS), 
lowering the primary and secondary standards from the 1997 standard of 
65 micrograms per cubic meter ([micro]g/m\3\) to 35 [micro]g/m\3\. On 
November 13, 2009 (74 FR 58688), the EPA designated a number of areas 
as nonattainment for the 24-hour PM2.5 NAAQS of 35 [micro]g/
m\3\, including the Logan, UT-ID nonattainment area. The EPA originally 
designated these areas under the general provisions of CAA title I, 
part D, subpart 1 (``subpart 1''), under which attainment plans must 
provide for the attainment of a specific NAAQS (in this case, the 2006 
PM2.5 standards) as expeditiously as practicable, but no 
later than five years from the date the areas were designated 
nonattainment.
    Following this designation of nonattainment for PM2.5 
and consistent with EPA guidance, the State of Utah and the State of 
Idaho developed PM2.5 attainment plans intended to meet the 
general requirements of subpart 1. Utah and Idaho each submitted a 
PM2.5 state implementation plan (SIP) for the Logan, UT-ID 
nonattainment area on December 14, 2012. On May 9, 2013, Utah submitted 
a SIP that contained multiple area source rules intended to reduce 
emissions in the PM2.5 nonattainment areas.
    Subsequently, on January 4, 2013, the U.S. Court of Appeals for the 
District of Columbia Circuit held that the EPA should have implemented 
the 2006 24-hour PM2.5 standard based on both the general 
nonattainment area requirements in subpart 1 and the PM-specific 
requirements of CAA title I, part D, subpart 4 (``subpart 4''). Under 
subpart 4, PM nonattainment areas are initially classified as Moderate, 
and Moderate area attainment plans must address the requirements of 
subpart 4 as well as subpart 1. Additionally, CAA subpart 4 establishes 
a different SIP submittal due date and attainment year. For a Moderate 
PM2.5 nonattainment area, the attainment SIP is due no later 
than 18 months after designation and the attainment year is as 
expeditiously as practicable after designation but no later than the 
end of the sixth calendar year after designation. On June 2, 2014 (79 
FR 31566), the EPA finalized the Identification of Nonattainment 
Classification and Deadlines for Submission of State Implementation 
Plan (SIP) Provisions for the 1997 Fine Particulate (PM2.5) 
NAAQS and 2006 PM2.5 NAAQS (``the Classification and 
Deadlines Rule''). This rule classified the areas that were designated 
in 2009 as nonattainment to Moderate, and set the attainment SIP 
submittal due date for those areas at December 31, 2014. This rule did 
not affect the Moderate area attainment date of December 31, 2015.
    After the court's decision, on December 16, 2014, the Utah 
Department of Air Quality (UDAQ) withdrew all prior Logan, UT-ID 
PM2.5 SIP submissions and submitted a new SIP to address 
both the general requirements of subpart 1 and the PM-specific 
requirements of subpart 4 for Moderate areas. Additionally, on December 
24, 2014, the Idaho Department of Environmental Quality (IDEQ) 
submitted a supplement to the 2012 SIP submission (``2014 amendment'') 
that included additional analyses intended to meet CAA subpart 4 
requirements.
    On August 24, 2016, the EPA finalized the Fine Particulate Matter 
National Ambient Air Quality Standards: State Implementation Plan 
Requirements (``PM2.5 Implementation Rule''), 81 FR 58010, 
which addressed the January 4, 2013 court ruling. The final 
implementation rule provides the EPA's interpretation of the 
requirements applicable to PM2.5 nonattainment areas and 
explains how air agencies can meet the statutory SIP requirements that 
apply under subparts 1 and 4 to areas designated nonattainment for any 
PM2.5 NAAQS, such as: General requirements for attainment 
plan due dates and attainment demonstrations; provisions for 
demonstrating reasonable further progress; quantitative milestones; 
contingency measures; nonattainment new source review (NNSR) permitting 
programs; and reasonably available control measures (RACM) (including 
reasonably available control technology (RACT). The statutory 
attainment planning requirements established in subparts 1 and 4 are 
designed to ensure that states implement measures that provide for 
attainment of the PM2.5 NAAQS as expeditiously as 
practicable by requiring states to adopt feasible emissions reduction 
strategies for PM2.5 and its precursors to achieve 
incremental reductions leading to attainment of the PM2.5 
NAAQS in nonattainment areas.

B. CAA Requirements for an Attainment Date Extension

    Under CAA section 188(d), the EPA may grant a state's request to 
extend the attainment date for a Moderate area if: ``(1) the state has 
complied with all requirements and commitments pertaining to the area 
in the applicable implementation plan; and (2) no more than one 
exceedance of the 24-hour [NAAQS] level for PM10 has 
occurred in the area in the year preceding the Extension Year, and the 
annual mean concentration for PM10 in the area for such year 
is less than or equal to the standard level.'' The EPA cannot issue

[[Page 25994]]

more than two, one-year extensions for a single Moderate area.
    The PM2.5 Implementation Rule interprets section 188(d) 
for PM2.5 Moderate areas. Under the regulations, the EPA may 
grant an extension if the agency determines that: (1) The state has 
complied with all requirements and commitments pertaining to the area 
in the applicable implementation plan; and (2) for an area designated 
nonattainment for the 24-hour PM2.5 NAAQS for which the 
state seeks an attainment date extension, the 98th percentile 24-hour 
concentration at each monitor in that area for the calendar year that 
includes the applicable attainment date is less than or equal to the 
level of the applicable 24-hour standard (calculated according to the 
data analysis requirements in 40 CFR part 50, appendix N). 40 CFR 
51.1005(a)(1). The applicable implementation plan is defined as the 
plan submitted to meet Moderate area requirements. Id. Sec.  
51.1005(a)(2). The PM2.5 Implementation Rule explains that, 
to meet the first criterion, a state needs to show that it has 
``submitted the necessary attainment plan for the area for the 
applicable PM2.5 NAAQS and is implementing the control 
measures in the submission.'' 81 FR 58070/3.
    In the absence of an attainment date extension, upon a 
determination of failure to attain by the EPA, the area would be 
reclassified to Serious by operation of law under CAA section 
188(b)(2). If an extension to the attainment date is granted, the EPA 
must determine whether the area attained the PM2.5 NAAQS at 
the end of the extension year. If the requisite three consecutive years 
of air quality data needed to determine attainment are still not 
available after the first extension, the state may apply for a second 
one-year extension of the attainment date if the requirements listed 
above for the first extension remain satisfied. The EPA will also 
consider the state's PM2.5 planning progress for the area in 
the year for which the first extension is granted, and if the area does 
not have the requisite three consecutive years of air quality data 
needed to demonstrate attainment at the end of the second extension, no 
further extensions of the attainment date can be granted. Once a final 
determination of failure to attain is made by the EPA and published in 
the Federal Register, the area will be reclassified as Serious by 
operation of law. See CAA section 188(b)(2).
    As a Moderate PM2.5 nonattainment area, the Logan, UT-ID 
nonattainment area was required by CAA section 188 to attain the 24-
hour PM2.5 NAAQS by December 31, 2015. On December 15, 2015, 
and February 26, 2016, the State of Idaho requested that the EPA use 
the discretion allowed under CAA section 188(d) to grant a one-year 
extension to the Moderate area attainment date for Logan, UT-ID, from 
December 31, 2015 to December 31, 2016. In a proposed action published 
December 16, 2016,\1\ the EPA denied Idaho's request because at the 
time the nonattainment area did not meet the air quality criterion 
under CAA section 188(d). Specifically, the Logan, Utah Federal 
Reference Method (FRM) monitor used for determining compliance with the 
PM2.5 NAAQS did not have complete and valid 2015 data in 
accordance with EPA regulations (81 FR 91088). As a result, the EPA 
could not determine that the data for the Logan monitor met the 98th 
percentile requirement set forth in 40 CFR 51.1005(a)(1).

hour Fine Particulate Matter National Ambient Air Quality Standards, 
81 FR 91088 (Dec. 16, 2016).
---------------------------------------------------------------------------

    Following this proposed action, and as a result of subsequent 
events described below, the State of Idaho submitted a letter on April 
25, 2017, requesting a second one-year Moderate area attainment date 
extension, from December 31, 2016 to December 31, 2017. On May 2, 2017, 
the State of Utah requested two, one-year extensions of the attainment 
date for the Logan, UT-ID nonattainment area, from December 31, 2015 to 
December 31, 2016, and then December 31, 2016 to December 31, 2017. 
Each of the extension requests from Idaho and Utah can be found in the 
Region 8 and Region 10 dockets for the Logan, UT-ID nonattainment area 
proposed extension request actions, EPA-R08-OAR-2017-0216 and EPA-R10-
OAR-2017-0193.

III. Basis for EPA's Proposed Action

A. Compliance With the Applicable SIP

    The PM2.5 Implementation Rule interprets the extension 
provisions found in CAA section 188(d)(1). See 40 CFR 51.1005(a)(1). 
Under the rule, a state must show that it submitted a SIP to meet the 
requirements as listed in 40 CFR 51.1003(a), including the necessary 
control measures, and that RACM/RACT and additional reasonable measures 
for sources in the area have been implemented. To qualify for an 
extension, the state must have adopted the SIP revision through the 
established state process, submitted the plan to the EPA, and begun 
implementing the plan; but the state plan would not need to have been 
approved by the EPA in order for the state to qualify for an extension.
    On December 4, 2012, UDAQ submitted a SIP for the Utah portion of 
the Logan, UT-ID PM2.5 nonattainment area, and was prepared 
to satisfy the requirements of CAA subpart 1, as interpreted by the 
EPA's Clean Air Fine Particle Implementation Rule (72 FR 20586, April 
25, 2007). After the January 4, 2013, D.C. Circuit ruling and 
subsequent EPA Classification and Deadlines Rule, the State of Utah 
withdrew the original SIP submittal and submitted an updated SIP to 
cover CAA subpart 1 and subpart 4 on December 22, 2014. This SIP 
includes: (1) A modeled attainment demonstration (chapter 5 of the SIP 
and chapter 4 of the technical support document (TSD)); (2) an 
emissions inventory (chapter 4 of the SIP and chapter 3 of the TSD); 
(3) RACM for area and on-road mobile sources (chapter 6 of the SIP and 
chapter 5 of the TSD); (4) a RACT review (chapter 6 of the SIP and 
chapter 5 of the TSD); (5) reasonable further progress for direct 
PM2.5, nitrogen oxides (NOX), sulfur dioxide 
(SO2), and volatile organic compounds (VOC) (chapter 8 of 
the SIP); (6) a demonstration that ammonia is not a significant 
precursor to PM2.5 in the area (chapter 4 of the TSD); (7) 
motor vehicle emission budgets (chapter 7 of the SIP); (8) quantitative 
milestones (chapter 8 of the SIP); and (9) contingency measures 
(chapter 9 of the SIP). The EPA intends to take action on the December 
22, 2014 SIP in the near future. The Utah SIP and supporting materials, 
including the TSD, can be found in the docket for this action. The 
Idaho SIP and supporting materials can be found in Region 10's docket, 
EPA-R10-OAR-2015-0067. Additionally, the supporting documentation for 
ID's two one-year extension requests can be found in Region 10's 
docket, EPA-R10-OAR-2017-0193.
    EPA has reviewed Utah's existing SIP and the December 22, 2014, SIP 
submission and determined that the state is implementing the 
requirements and commitments in the submitted SIP. Based on this, the 
EPA proposes to determine that the state meets the criterion found in 
40 CFR 51.1005(a)(1)(i). The control measures that Utah submitted for 
the Logan UT-ID NAA consist of a vehicle inspection and maintenance (I/
M) program and area source rules. The EPA approved the vehicle I/M 
program on September 9, 2015 (80 FR 54237). The program was initiated 
on January 1, 2014, and requires a biennial test for vehicles greater 
than six years old that are of model year 1969 and newer. Half of

[[Page 25995]]

these vehicles were tested for the first time in 2014 and the rest were 
tested in 2015; prior to the attainment date for the area. The EPA has 
also approved or conditionally approved the area source rules submitted 
by the State. 81 FR 9343; 81 FR 71988. Some of the area source rules 
were implemented as early as January 1, 2013, but most carried an 
implementation date of December 1, 2014. All of them were effective and 
fully enforceable by January 1, 2015.
    Similarly, the EPA approved Idaho's woodstove curtailment 
ordinances, burn ban, heating device restrictions, and woodstove 
change-out programs as meeting the RACM/RACT requirements in this area 
(82 FR 729, January 4, 2017). The woodstove curtailment ordinances, 
burn ban, and heating device restrictions were adopted and fully 
implemented in the summer and fall of 2012 in preparation for Idaho's 
December 14, 2012 attainment plan SIP revision. The residential 
woodstove change-out program was conducted in 2011 to 2012, with a 
subsequent round of change-outs in 2013 to 2014. A full description of 
the control measures is included in our December 26, 2013 proposed 
approval (78 FR 78315) and March 25, 2014 final approval (79 FR 16201). 
On April 25, 2017, Idaho committed to supplementing the 2012 attainment 
plan SIP revision, and Idaho's December 24, 2014 amendment to the 
attainment plan SIP revision, to comply with the revised regulatory 
requirements of the 2016 PM2.5 Implementation Rule for 
reasonable further progress, quantitative milestones, and motor vehicle 
emissions budgets. The EPA's proposed conditional approval of these SIP 
elements is addressed under docket number EPA-R10-OAR-2015-0067.
    The EPA proposes that the criterion found in 40 CFR 
51.1005(a)(1)(i) has been met. Utah and Idaho submitted SIPs for the 
Logan, UT-ID Moderate PM2.5 nonattainment area that address 
the CAA requirements for Moderate areas and the states have implemented 
the permanent and enforceable control measures identified above and the 
other requirements of the SIPs.

B. Air Quality Data

    In accordance with 40 CFR part 58, UDAQ and IDEQ both operate 
PM2.5 monitors in the Logan, UT-ID PM2.5 
nonattainment area. The IDEQ monitoring site for 2015 and 2016 was 
located in Franklin, Idaho. In 2015, UDAQ operated two PM2.5 
monitoring sites, at Logan and Smithfield, and in 2016, UDAQ operated 
only the Smithfield monitoring site. In the past, the monitor with the 
highest air quality design value in the nonattainment area has been 
located in Utah.
    As explained in the May 8, 2017 memorandum in the docket, a large 
number of samples from the filter-based FRM monitor at Logan were 
invalid. After review of the PM2.5 data for 2015, UDAQ 
removed the invalid samples for its filter based FRM monitor and left 
the valid samples in the Air Quality System (AQS) database. 
Additionally, some continuous sampler data from a co-located Federal 
Equivalent Methods (FEM) monitor were determined to have sufficient 
quality assurance to meet NAAQS comparison requirements. The Logan site 
had one FEM monitor co-located at the site, and data from this monitor 
were used to fill in some of the missing days in 2015, adding to the 
total number of samples that can be used to determine a 98th percentile 
value for that year and to provide for a complete 2015 monitoring year. 
Utah used the methodology found in 40 CFR part 50, appendix N 3.0(d)(2) 
and 40 CFR part 50, appendix N 3.0(e) to substitute FEM data for the 
days without FRM data.
    The EPA has reviewed this site and, using the criteria found in 40 
CFR part 58, appendix A, has determined that the quality assurance (QA) 
for the continuous FEM monitor is acceptable such that data from the 
FEM monitor can be substituted for the days for which the FRM monitor 
data was invalid. Additional information related to these monitors can 
be found in the November 23, 2016 memoranda found in the docket for 
this proposed action.
    On March 14, 2017, the EPA approved Utah's 2016 Annual Monitoring 
Network Plan (AMNP). As part of the approval, the EPA approved the 
closing of the Logan monitoring station (AQS ID# 49-005-0004) and the 
opening of the Smithfield monitoring station (AQS ID# 49-005-0007). The 
Logan and Smithfield monitoring stations both ran in 2015; however, the 
Smithfield monitoring site data was incomplete for 2015 because the 
station, including the co-located continuous monitor, was not operating 
in January of that year. The Logan monitoring site shut down on 
December 31, 2015, and Smithfield became the only operating monitor in 
the Utah portion of the Logan, UT-ID PM2.5 nonattainment 
area. Additionally, on April 20, 2017, UDAQ submitted a letter that 
contained the AMP 600 and AMP 450NC reports required to certify the 
2016 air quality data in Utah. UDAQ completed the data certification 
process in AQS and with the April 20, 2017 letter, certifies that the 
2016 air quality data is accurate.
    The EPA is using data from calendar year 2015 to determine whether 
the Logan, UT-ID PM2.5 nonattainment area met the air 
quality criteria for granting a one-year extension of the attainment 
date, from December 31, 2015 to December 31, 2016, under CAA section 
188(d). Additionally, the EPA is using calendar year 2016 data to 
determine whether the Logan, UT-ID PM2.5 nonattainment area 
met the air quality criteria for granting an extension of the 
attainment date from December 31, 2016 to December 31, 2017.
    In 2015, the 98th percentile for the Logan, UT-ID PM2.5 
nonattainment area at the Logan (Utah) and Franklin (Idaho) monitoring 
sites were 29.0 [micro]g/m\3\ and 18.8 [micro]g/m\3\, respectively, 
which are both below the 35 [micro]g/m\3\ standard. Thus, the area met 
the requirement to qualify for a one-year attainment date extension 
under CAA section 188(d)(2). See 40 CFR 51.1005(a)(1)(ii). In 2016, the 
98th percentile for the Logan, UT-ID PM2.5 nonattainment 
area at the Smithfield (Utah) and Franklin (Idaho) monitoring sites 
were 34.4 [micro]g/m\3\ and 33.3 [micro]g/m\3\, respectively, which are 
both below the 35 [micro]g/m\3\ standard. Thus, the area met the 
requirements to qualify for a second one-year attainment date extension 
under CAA section 188(d)(2). Based on the information above, the 
criterion in 40 CFR 51.1005(a)(1)(ii) has been met for both one-year 
extensions.

IV. EPA's Proposed Action

    In response to requests from the Governor of Utah on May 2, 2017, 
and from the IDEQ on December 15, 2015, February 26, 2016, and April 
25, 2017, the EPA is proposing to grant two, one-year attainment date 
extensions to the Moderate attainment date for the 2006 24-hour 
PM2.5 NAAQS for the Logan, UT-ID nonattainment area. If 
finalized, this action would extend the Moderate area attainment date 
for the Logan, UT-ID nonattainment area from December 31, 2015 to 
December 31, 2016, and from December 31, 2016 to December 31, 2017. The 
proposed action to extend the Moderate attainment date for this 
nonattainment area is based on both states' compliance with the 
requirements for the applicable SIPs for the area and on the 2015 and 
2016 PM2.5 98th percentile data from the Logan (Utah), 
Smithfield (Utah), and Franklin (Idaho) monitoring sites in the Logan, 
UT-ID nonattainment area. If we finalize this proposal, consistent with 
CAA section 188(d) and 40 CFR 51.1005(a)(1), the nonattainment area 
will remain a Moderate PM2.5 nonattainment area, with a 
Moderate area attainment date of December 31, 2017. Additionally, the 
states will not have to submit the additional planning requirements 
that apply to Serious PM2.5 nonattainment

[[Page 25996]]

areas unless the area fails to attain the standard by the extended 
Moderate area attainment date and the area is reclassified to a Serious 
PM2.5 nonattainment area. Consistent with CAA section 
188(b)(2), the EPA will determine whether the area attained the 
standard within six months following the applicable attainment date.
    This action is not a redesignation to attainment under CAA section 
107(d)(3)(E). Utah and Idaho are not currently attaining the NAAQS and 
have not submitted maintenance plans as required under section 175(A) 
of the CAA or met the other statutory requirements for redesignation to 
attainment. The designation status in 40 CFR part 81 will remain a 
Moderate nonattainment area until such time as Utah and Idaho meet the 
CAA requirements for redesignation to attainment or the area is 
reclassified to Serious.

V. Statutory and Executive Order Reviews

    Additional information about these statutes and Executive Orders 
can be found at http://www2.epa.gov/laws-regulations/laws-and-executive-orders.

A. Executive Order 12866: Regulatory Planning and Review and Executive 
Order 13563: Improving Regulation and Regulatory Review

    This action is not a significant regulatory action and therefore is 
not subject to review by the Office of Management and Budget (OMB). 
This proposed action merely approves a state request as meeting federal 
requirements and imposes no new requirements.

B. Paperwork Reduction Act (PRA)

    This action does not impose any additional information collection 
burden under the provisions of the PRA, 44 U.S.C. 3501 et seq. This 
action merely approves a state request for an attainment date 
extension, and this action does not impose additional requirements 
beyond those imposed by state law.

C. Regulatory Flexibility Act (RFA)

    I certify that this action will not have a significant economic 
impact on a substantial number of small entities under the RFA. This 
action will not impose any requirements on small entities beyond those 
imposed by state law. Approval of a state's request for an attainment 
date extension does not create any new requirements and does not 
directly regulate any entities.

D. Unfunded Mandates Reform Act (UMRA)

    This action does not contain any unfunded mandate as described in 
UMRA, 2 U.S.C. 1531-1538, and does not significantly or uniquely affect 
small governments. This action does not impose additional requirements 
beyond those imposed by state law. Accordingly, no additional costs to 
state, local, or tribal governments, or to the private sector, will 
result from this action.

E. Executive Order 13132: Federalism

    This action does not have federalism implications. It will 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. Pursuant 
to the CAA, this action merely approves a state request for an 
attainment date extension.

F. Executive Order 13175: Coordination With Indian Tribal Governments

    This action does not have tribal implications, as specified in 
Executive Order 13175. No tribal areas are located in the nonattainment 
area that will be receiving an attainment date extension. The CAA and 
the Tribal Authority Rule establish the relationship of the federal 
government and tribes in developing plans to attain the NAAQS, and this 
rule does nothing to modify that relationship. Thus, Executive Order 
13175 does not apply to this action.

G. Executive Order 13045: Protection of Children From Environmental 
Health Risks and Safety Risks

    This action is not subject to Executive Order 13045 because it is 
not economically significant as defined in Executive Order 12866, and 
because the EPA does not believe any environmental health or safety 
risks addressed by this action present a disproportionate risk to 
children. This action merely approves a state request for an attainment 
date extension and it does not impose additional requirements beyond 
those imposed by state law.

H. Executive Order 13211: Actions That Significantly Affect Energy 
Supply, Distribution, or Use

    This action is not subject to Executive Order 13211, because it is 
not a significant regulatory action under Executive Order 12866.

I. National Technology Transfer and Advancement Act (NTTAA)

    This rulemaking does not involve technical standards. This action 
merely approves a state request for an attainment date extension.

J. Executive Order 12898: Federal Actions To Address Environmental 
Justice in Minority Populations and Low-Income Population

    The EPA believes that this action does not have disproportionately 
high and adverse human health or environmental effects on minority 
populations, low-income populations and/or indigenous peoples, as 
specified in Executive Order 12898 (59 FR 7629, February 16, 1994). 
This action approves a state request for an attainment date extension 
based on the state's compliance with requirements and commitments in 
its plan and recent air quality monitoring data that meets requirements 
for an extension.
