Clean Data Determination; Provo, Utah 2006 Fine Particulate
Matter Standards Nonattainment Area
AGENCY: Environmental Protection Agency.
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is proposing to make
a clean data determination (CDD) for the 2006 24-hour fine particulate
matter (PM2.5) Provo, Utah (UT) nonattainment area (NAA).
The proposed determination is based upon quality-assured, quality-
controlled, and certified ambient air monitoring data for the period
2015-2017, available in the EPA's Air Quality System (AQS) database,
showing the area has monitored attainment of the 2006 24-hour
PM2.5 National Ambient Air Quality Standards (NAAQS). Based
on our proposed determination that the Provo, UT NAA is currently
attaining the 24-hour PM2.5 NAAQS, the EPA is also proposing
to determine that the obligation for Utah to make submissions to meet
certain Clean Air Act (CAA or the Act) requirements related to
attainment of the NAAQS for this area is not applicable for as long as
the area continues to attain the NAAQS.

SUPPLEMENTARY INFORMATION: Throughout this document, wherever ``we'',
``us'' or ``our'' is used, it is intended to refer to the EPA.
I. Background
On October 17, 2006 (71 FR 61144), the EPA revised the level of the
24-hour PM2.5 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\. The EPA retained the form of the
1997 24-hour standard, that is, the 98th percentile of the annual 24-
hour concentrations at each population-oriented monitor within an area,
averaged over 3 years. See 71 FR 61164-5 (October 17, 2006).
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 Provo, UT NAA. 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 5 years from the date the areas were designated
nonattainment.
Subsequently, on January 4, 2013, the U.S. Court of Appeals for the
District of Columbia Circuit held in NRDC v. EPA \1\ that the EPA
should have implemented the 2006 24-hour PM2.5 standard
based on both the general NAA requirements in subpart 1 and the PM-
specific requirements of CAA title I, part D, subpart 4 (``subpart
4''). In response to the Court's decision in NRDC v. EPA, 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.'' 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. After the court's decision and the EPA's June 2,
2014 rule, on December 16, 2014 the Utah Division of Air Quality (UDAQ)
withdrew all prior Provo, UT 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.
---------------------------------------------------------------------------
\1\ 706 F.3d 428 (D.C. Cir. 2013).
---------------------------------------------------------------------------
On August 24, 2016, the EPA finalized the Fine Particulate Matter
National Ambient Air Quality Standards: State Implementation Plan
Requirements (``PM2.5 SIP Requirements Rule''), 81 FR 58010,
which addressed the January 4, 2013, court ruling. The final
PM2.5 SIP Requirements Rule provides the EPA's
interpretation of the requirements applicable to PM2.5 NAAs
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.
The EPA has previously acted on portions of Utah's Moderate area
attainment plan for the Provo, UT NAA. Specifically, we approved
certain area source rules and related reasonably available control
measure (RACM) analyses on February 25, 2016 (81 FR 9343), October 19,
2016 (81 FR 71988) and September 14, 2017 (82 FR 43205). We have not
disapproved any portions of the plan; as a result, the clocks for
sanctions under 179(a) and for a Federal Implementation Plan (FIP)
under 110(c) are not in effect for the Provo, UT NAA.
Finally, on May 10, 2017 (82 FR 21711), the EPA determined that the
Provo, UT NAA failed to attain the 2006 24-hour PM2.5 NAAQS
by the Moderate attainment date of December 31, 2015. With this
determination, the Provo, UT NAA was reclassified as a ``Serious'' area
for the 2006 24-hour PM2.5 NAAQS, with a new attainment date
of December
[[Page 3374]]
31, 2019. This reclassification triggered an obligation for Utah to
submit a new, Serious area attainment plan consisting of several
elements, including a control strategy and demonstration of attainment
by the new attainment date. See 40 CFR 51.1003(b)(1).
II. Clean Data Determination
Over the past two decades, the EPA has consistently applied its
``Clean Data Policy'' interpretation to attainment related provisions
of Part D of the CAA. The EPA codified the Clean Data Policy in the
PM2.5 SIP Requirements Rule (40 CFR 51.1015(a)) for the
implementation of current and future PM2.5 NAAQS. See 81 FR
58010, 58161 (August 24, 2016). For a complete discussion of the Clean
Data Policy's history and the EPA's longstanding interpretation under
the CAA, please refer to the PM2.5 SIP Requirements Rule.
As codified at 40 CFR 51.1015(a) in the PM2.5 SIP
Requirements Rule, upon a determination by the EPA that a Moderate
PM2.5 NAA has attained the PM2.5 NAAQS, the
requirements for the State to submit an attainment demonstration,
provisions demonstrating timely implementation of RACM (including
reasonably available control technology (RACT)), a reasonable further
progress (RFP) plan, quantitative milestones and quantitative milestone
reports, and contingency measures shall be suspended. Additionally,
under 40 CFR 51.1015(b), upon determination by the EPA that a Serious
PM2.5 NAA has attained the PM2.5 NAAQS, the
requirements for the State to submit an attainment demonstration, RFP,
quantitative milestones and quantitative milestone reports, and
contingency measures for the area will be suspended. However, the EPA's
longstanding policy for the best available control measure (BACM)/best
available control technology (BACT) requirement of CAA section
189(b)(1)(B) is that the requirement is independent of attainment.
Thus, a CDD would not suspend the obligation for UDAQ to submit any
applicable outstanding BACM/BACT requirements or other requirements
that are independent of attainment.
By extension, the requirement to submit a motor vehicle emission
budget (MVEB) for the attainment year (both for a Moderate and Serious
NAA) for the purposes of transportation conformity is also suspended. A
MVEB is that portion of the total allowable emissions defined in the
submitted or approved control strategy implementation plan revision or
maintenance plan for a certain date for the purpose of meeting RFP
milestones or demonstrating attainment or maintenance of the NAAQS, for
any criteria pollutant or its precursors, allocated to highway and
transit vehicle use and emissions.\2\ For the purposes of the
transportation conformity regulations, the control strategy
implementation plan revision is the implementation plan which contains
specific strategies for controlling the emissions of and reducing
ambient levels of pollutants in order to satisfy CAA requirements for
demonstrations of RFP and attainment.\3\ Given that MVEBs are required
to support the RFP and attainment demonstration requirements in the
attainment plan, suspension of the RFP and attainment demonstration
requirements through a CDD also suspends the requirement to submit
MVEBs for the attainment and RFP years. The suspension of planning
requirements pursuant to 40 CFR 51.1015 does not preclude the State
from submitting suspended elements of its Moderate and Serious area
attainment plans for the EPA approval for the purposes of strengthening
the State's SIP.
---------------------------------------------------------------------------
\2\ 40 CFR 93.101.
\3\ 40 CFR 93.101.
---------------------------------------------------------------------------
The planning elements under subpart 1 and subpart 4 generally
include RFP, attainment demonstrations, RACM/RACT, NAA contingency
measures, and other state planning requirements related to attaining
the NAAQS.\4\ The suspension of the obligation to submit such
requirements applies regardless of when the plan submissions are due.
The CDD does not suspend CAA requirements that are independent of
helping the area achieve attainment, such as the requirements to submit
an emissions inventory, nonattainment new source review (NNSR), and
BACM/BACT requirements. The determination of attainment is not
equivalent to a redesignation, and the State must still meet the
statutory requirements for redesignation in order to be redesignated to
attainment.
---------------------------------------------------------------------------
\4\ PM2.5 SIP Requirements Rule (81 FR 58010).
---------------------------------------------------------------------------
In accordance with 40 CFR 51.1015(a) and (b), the CDD suspends the
aforementioned SIP obligations until such time as the area is
redesignated to attainment, after which such requirements are
permanently discharged; or the EPA determines that the area has re-
violated the PM2.5 NAAQS, at which time the State shall
submit such attainment plan elements for the Moderate and Serious NAA
plans by a future date to be determined by the EPA and announced
through publication in the Federal Register at the time the EPA
determines the area is violating the PM2.5 NAAQS.
A. Monitoring Network Considerations
Determining whether an area has attained the NAAQS is based on
monitored air quality data; thus, the validity of a determination of
attainment depends in part on whether the monitoring network adequately
measures ambient PM2.5 levels in the NAA. The UDAQ is the
governmental agency with the authority and responsibilities under the
State's laws for collecting ambient air quality data for the Provo, UT
NAA and submitting the data to AQS. UDAQ annually certifies that the
data they submit to AQS are quality assured. UDAQ also submits an
annual monitoring network plan (AMNP) to the EPA. These plans discuss
the status of the air monitoring network, as required under 40 CFR part
58. With respect to PM2.5 monitoring in the Provo, UT NAA,
the EPA found that UDAQ's annual network plans met the applicable
requirements under 40 CFR part 58 for the relevant period, 2015-2017,
with the exception (discussed below) of UDAQ's 2015 network plan.\5\
The UDAQ operated three PM2.5 State and Local Air Monitoring
Station (SLAMS) monitors during the 2015-2017 period within the Provo,
UT PM2.5 NAA: North Provo, Lindon and Spanish Fork.
---------------------------------------------------------------------------
\5\ In letters dated April 20, 2017, and April 10, 2018, UDAQ
completed the data certification process in AQS and certified that
the 2016 and 2017 air quality data are accurate. The 2015 data is
discussed below with the discussion of UDAQ's 2015 network plan.
---------------------------------------------------------------------------
B. Provo, UT Monitoring During 2015
UDAQ submitted the 2015 AMNP and 5-Year Network Assessment in June
2015. UDAQ's submissions were not reviewed and acted on by Region 8
because the Region was conducting a Technical Support Audit (TSA) of
UDAQ's ambient air monitoring program at the time. The TSA was
completed in August 2015 and found major and minor/observation issues
with the monitoring program. The objective of a TSA is to review a
monitoring program's quality assurance (QA) system, in this case the
reporting of valid data to the EPA's AQS database. See 40 CFR part 58,
appendices A through E. A major finding may indicate that invalid data
have been loaded in AQS or that future operations may result in the
collection of invalid data. A minor/observation finding will not
necessarily lead to data loss or invalidation, but warrants
investigation, appropriate follow-up, and audit response. Additional
details pertaining to the major and minor findings can be
[[Page 3375]]
found in the August 2015 TSA, available in the docket.
Due to these monitoring issues, the EPA did not approve UDAQ's 2015
AMNP and a large number of samples from the filter-based Federal
Reference Method (FRM) monitors in the Provo, UT NAA were
invalidated.\6\ The EPA worked with UDAQ to correct the deficiencies
found in the August 2015 TSA and after their review of the
PM2.5 data for 2015, UDAQ removed the invalid samples for
the Provo, UT FRM monitors and left the valid samples in the AQS
database. However, some continuous sampler data from the Provo, UT co-
located Federal Equivalent Method (FEM) monitors were determined to
have sufficient QA to meet NAAQS comparison requirements. Data from
these co-located monitors 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 providing for a
complete 2015 monitoring year. Utah used the methodology found in 40
CFR part 50, appendix N 3.0(d)(2) and 3.0(e) to substitute FEM data for
the days without FRM data.
---------------------------------------------------------------------------
\6\ April 19, 2017 EPA Region 8 Memorandum; Salt Lake and Provo,
Utah PM2.5 2013-2015 24-hour Design Value.
---------------------------------------------------------------------------
The EPA has reviewed the Provo, UT monitoring sites and, using the
criteria found in 40 CFR part 58, appendix A, has determined that the
QA for the continuous FEM monitors is acceptable. We therefore agree
that the data from the FEM monitors can be substituted for the days for
which the FRM monitor data was invalid. The data from the FEM monitor
at the Spanish Fork monitoring site was used to substitute for invalid
FRM data; however, 2015 was still incomplete. Further discussion on the
Spanish Fork monitoring site can be found below.
On November 29, 2016, UDAQ submitted a letter that contained the
Air Monitoring Program (AMP) 430, AMP 450, AMP 256, and AMP 450NC
reports required to certify the 2015 air quality data in Utah. UDAQ
completed the data certification process in AQS and with the November
29, 2016 letter, certified that the 2015 air quality data is accurate.
Additional information related to these monitors can be found in the
November 23, 2016 memoranda found in the docket for this proposed
action. Additional details and evaluation of the 2015-2017 AMNPs can be
found in our notice proposing to issue a CDD for the Logan, UT-ID
Moderate PM2.5 nonattainment area. See 83 FR 33886 (July 18,
2018). The Logan, UT-ID CDD was subsequently finalized on October 19,
2018 (83 FR 52983).
C. Evaluation of Current Attainment
The EPA's evaluation of whether the Provo, UT PM2.5 NAA
has attained the 2006 24-hour PM2.5 NAAQS is based on our
review of all valid monitoring data ``produced by suitable monitors
that are required to be submitted to AQS, or otherwise available to EPA
. . . .'' See Appendix N, 3.0(a). Based on our review, the
PM2.5 monitoring network for the Provo, UT NAA meets the
requirements stated above and is therefore adequate for use in
determining whether the area attained the 2006 24-hour PM2.5
NAAQS.
The EPA reviewed the PM2.5 ambient air monitoring data
from the North Provo (AQS site 49-049-0002), Lindon (AQS site 49-049-
4001), and Spanish Fork (AQS site 49-049-5010) monitoring sites
consistent with the requirements contained in 40 CFR part 50, as
recorded in the EPA AQS database for the Provo, UT NAA. As shown in
Table 1 below, the North Provo monitor in the Provo, UT NAA has
collected complete data since 2011 and is trending downward overall.
The Lindon monitor had incomplete data in 2012; however, all other
years have been complete and the monitor shows a downward trend too.
The Spanish Fork monitor had incomplete data during the first
quarter of 2015 and 2016 and is not eligible for the high value data
substitution test in 40 CFR part 50, appendix N. However, based upon
the analysis detailed in the monitoring memorandum located in the
docket for today's action,\7\ the EPA has preliminarily determined that
the upper end of the probable range for the 2015-2017 design value at
the Spanish Fork monitor (30 [micro]g/m\3\) is well below the NAAQS. As
a result, the EPA has preliminarily concluded that the Provo, UT NAA
continues to meet the 2006 24-hour PM2.5 NAAQS of 35
[micro]g/m\3\ for the period 2015-2017, the most recent 3-year period
of certified data availability. Should there be a subsequent violation
of the 2006 PM2.5 standards in the Provo, UT NAA, the EPA
will withdraw the CDD.

D. Clean Data Determination for the Provo, UT Nonattainment Area
Based on the monitoring data for the period 2015-2017, the EPA is
proposing to determine that the area has clean data for demonstrating
attainment of the 2006 24-hr PM2.5 NAAQS. In accordance with
40 CFR 51.1015, a CDD can be made upon a determination by the EPA that
a Moderate or Serious PM2.5 NAA is attaining the
PM2.5 NAAQS. As provided in 40 CFR 51.1015, so long as this
area continues to meet the standard, finalization of this determination
suspends the requirements for this area to submit an attainment
demonstration, associated RACM/RACT, RFP plan, contingency measures,
and any other planning SIP requirements related to the attainment of
the 2006 PM2.5 NAAQS. For purposes of this NAAQS, the
requirements to submit a projected attainment inventory as part of an
attainment demonstration or RFP as well as a MVEB are also suspended by
this determination.
As discussed in the PM2.5 SIP Requirements Rule, the
nonattainment base emissions inventory required by section 172(c)(3) is
not suspended by this determination because the base
[[Page 3376]]
inventory is a requirement independent of planning for an area's
attainment. See 81 FR 58009 at 58028 and 58127-8 and 80 FR 15340 at
15441-2. Additionally, NNSR requirements are discussed in the
PM2.5 SIP Requirements Rule and required by CAA sections
110(a)(2)(C); 172(c)(5); 173; 189(a); and 189(e), as not being
suspended by a CDD because this requirement is independent of the
area's attainment planning. See 81 FR 58010 at 58107 and 58127.
Furthermore, the BACM/BACT requirements found in CAA section
189(b)(1)(B) are not suspended with a CDD for a Serious NAA due to this
requirement being independent of attainment. See 81 FR 58010 at 58128.
Under the proposed CDD, the planning requirements noted above (for
both Moderate and Serious areas) shall be suspended, until such time as
the area is redesignated to attainment, after which such requirements
are permanently discharged. This proposed action, if finalized, will
not constitute a redesignation to attainment under CAA section
107(d)(3)(E), because the State must have an approved maintenance plan
for the area as required under section 175A of the CAA, and the EPA
must determine that the area has met the other requirements for
redesignation in order to be redesignated to attainment. The
designation status of the area will remain nonattainment for the 2006
PM2.5 NAAQS until such time as the EPA determines that the
area meets the CAA requirements for redesignation to attainment under
CAA section 107(d)(3)(E).
It is possible, although not expected, that the Provo, UT area
could violate the 24-hour PM2.5 NAAQS before a maintenance
plan is adopted, submitted, and approved, and the area is redesignated
to attainment. Under 40 CFR 51.1015(a)(2) and (b)(2), if the EPA
determines that the area has re-violated the 24-hour PM2.5
NAAQS, the EPA will rescind the CDD and the State shall be required to
submit the suspended attainment plan elements. Even so, submission of
the suspended elements may be insufficient to eliminate future
violations. Therefore, the issuance of a SIP call under section
110(k)(5) could be an appropriate response. This SIP call could require
the State to submit, by a reasonable deadline not to exceed 18 months,
a revised plan demonstrating expeditious attainment and complying with
other requirements applicable to the area at the time of this finding.
Under CAA section 172(d), the EPA may reasonably adjust the dates
applicable to these requirements.
III. Proposed Action
The EPA is proposing to make a CDD for the 2006 24-hour
PM2.5 Provo, Utah (UT) NAA based on the area's current
attainment of the standard. Pursuant to 40 CFR 51.1015(a) and (b), the
EPA proposes to determine that the obligation to submit any remaining
attainment-related SIP revisions arising from classification of the
Provo, UT area as a Moderate NAA and subsequent reclassification as a
Serious NAA under subpart 4 of part D (of title I of the Act) for the
2006 24-hour PM2.5 NAAQS is not applicable for so long as
the area continues to attain the 2006 24-hour PM2.5 NAAQS.
However, the CDD does not suspend UDAQ's obligation to submit non-
attainment-related requirements, which includes the base-year emission
inventory, NNSR revisions, and BACM/BACT. This proposed action, if
finalized, would not constitute a redesignation to attainment under CAA
section 107(d)(3).
IV. Statutory and Executive Order Reviews
This action proposes to issue a determination of attainment based
on air quality and to suspend certain federal requirements, and thus,
would not impose additional requirements beyond those imposed by state
law. For this 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 section 12(d) of the
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272
note) because application of those requirements would be inconsistent
with the CAA; and
Does not provide EPA with the discretionary authority to
address, as appropriate, disproportionate human health or environmental
effects, using practicable and legally permissible methods, under
Executive Order 12898 (59 FR 7629, February 16, 1994).
In addition, this proposed action does not 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).
