40 CFR Part 52

[EPA-R08-OAR-2011-0727, FRL-9901-92-Region 8]


Promulgation of State Implementation Plan Revisions; Revision to 
Prevention of Significant Deterioration Program; Infrastructure 
Requirements for the 1997 and 2006 PM[bdi2].[bdi5] National 
Ambient Air Quality Standards; Utah

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: EPA is partially approving and partially disapproving State 
Implementation Plan (SIP) submissions from the State of Utah to 
demonstrate that the SIP meets the infrastructure requirements of the 
Clean Air Act (CAA) for the National Ambient Air Quality Standards 
(NAAQS) promulgated for fine particulate matter (PM2.5) on 
July 18, 1997 and on October 17, 2006. The CAA requires that each 
state, after a new or revised NAAQS is promulgated, review their SIPs 
to ensure that they meet infrastructure requirements. The State of Utah 
provided infrastructure SIP submissions on April 17, 2008 for the 1997 
PM2.5 NAAQS and September 21, 2010 for the 2006 
PM2.5 NAAQS. In addition, EPA is approving portions of SIP 
revisions submitted by the State of Utah on March 14, 2012. This 
submission revises Utah's Prevention of Significant Deterioration (PSD) 
program to incorporate the required elements of the 2008 
PM2.5 New Source Review (NSR) Implementation Rule and the 
2010 PM2.5 Increment Rule.

DATES: This final rule is effective November 25, 2013.

I. Background

    Infrastructure requirements for SIPs are provided in section 
110(a)(1) and (2) of the CAA. Section 110(a)(2) lists the specific 
infrastructure elements that a SIP must contain or satisfy. The 
elements that are the subject of this action are described in detail in 
our notice of proposed rulemaking (NPR) of May 23, 2013 (78 FR 30830).
    In our NPR, we proposed to act on submissions from the State of 
Utah to address infrastructure requirements for the 1997 and 2006 
PM2.5 NAAQS. The NPR proposed approval of the submissions 
with respect to the

[[Page 63884]]

following infrastructure elements for the 1997 and 2006 
PM2.5 NAAQS: CAA Sections 110(a)(2)(A), (B), (C) with 
respect to minor NSR requirements, (E), (F), (G), (H), (J) with respect 
to the requirements of sections 121 and 127 of the Act, (K), (L), and 
(M). The reasons for our approval are provided in detail in the NPR.
    For reasons explained in the NPR, EPA also proposed to approve the 
submissions for infrastructure elements (C) and (J) with respect to PSD 
requirements for the 1997 and 2006 PM2.5 NAAQS. 
Concurrently, EPA proposed to approve revisions to the Utah SIP 
submitted by the State on March 14, 2012 which incorporate the 
requirements of the 2008 PM2.5 NSR Implementation Rule and 
the 2010 PM2.5 Increment Rule; specifically, approval of the 
text of 40 CFR 52.21, paragraphs (b)(14)(i), (ii), and (iii); 
(b)(15)(i) and (ii); (b)(23)(i); (b)(50); and, paragraph (c) as they 
existed on July 1, 2011. EPA is taking no action at this time on 
infrastructure element (D) for the 2006 PM2.5 NAAQS.
    EPA also proposed to correct, under section 110(k)(6) of the CAA, 
an erroneous statement made in a previous action on Utah's 
infrastructure SIP submission for the 1997 ozone NAAQS. As explained in 
more detail in our proposal, in EPA's action on the 1997 ozone 
infrastructure submittal, EPA erroneously stated that the CAA made no 
requirements for state judicial review of PSD permits.

II. Response to Comments

    Comment: Three trade associations opposed our proposed disapproval 
of Utah's infrastructure SIP with respect to element 110(a)(2)(E)(ii). 
The commenters acknowledge that Utah's state law governing the Utah Air 
Quality Board (Board) was amended by Senate Bill 21 in 2011 to remove 
the provision in Utah Code section 19-2-203 requiring members of the 
Board to adequately disclose potential conflicts of interest. However, 
the commenters cite another provision, added in Senate Bill 21 to Utah 
Code section 19-1-201, requiring the Utah Department of Environmental 
Quality (Department) to promulgate rules regarding conflict of interest 
procedures for the Board. The commenters therefore disagree with our 
statement that Utah Code section 19-2-203 does not address disclosure 
of potential conflicts of interest by members of the Board, and our 
statement that the 2008 and 2010 infrastructure submittals no longer 
reflect state law. The commenters cite conflict of interest rules 
promulgated by the Department in Utah Administrative Code (UAC) 
sections R305-9-101 to -106 and note that the Director is a member of 
the Board and is thus subject to these rules. As a result, the 
commenters also take exception to our statement that Utah Code section 
19-2-203 does not address disclosure of conflicts of interest by the 
Director, and state that they have ``no idea'' why EPA did not take the 
rules promulgated in UAC sections R305-9-101 to -106 into account in 
our proposal. The commenters conclude, based on the revisions to Utah 
Code section 19-1-203 and the rules in Utah Administrative Code section 
R305-9, that the infrastructure SIP should be approved for CAA element 
110(a)(2)(E)(ii).
    Response: EPA disagrees with this comment. First, we stated a 
general principle in our proposed action: section 128 must be satisfied 
through federally enforceable provisions that are approved into the 
SIP. See 78 FR at 52842 n.5 (citing 78 FR 32613 (May 31, 2013)). The 
language of section 128 compels this. It mandates that each SIP 
``contain requirements'' meeting the terms of subsections 128(a)(1) and 
(a)(2). In turn, section 110(a)(2)(E)(ii) requires section 128 to be 
satisfied. The commenters do not dispute any of this.
    EPA correctly stated that the infrastructure SIP submittals no 
longer reflect state law. As stated in our proposal, the submittals 
were made on April 17, 2008 and September 21, 2010, for the 1997 
PM2.5 and 2006 PM2.5 NAAQS, respectively. Also 
stated in our proposal, S.B. 21 was enacted in 2011, after the 
submittals were made. In other words, state law changed after the 
submittals were made.
    EPA also correctly stated that revised Utah Code section 19-2-203 
does not address disclosure of potential conflicts of interest. To the 
extent that EPA should have considered the revisions to Utah Code 
section 19-1-201 (which were not referenced in the infrastructure SIP 
submittals nor separately submitted for inclusion in the SIP), a 
general requirement such as that in section 19-1-203 to promulgate 
conflict of interest rules nonetheless does not address how potential 
conflicts of interest will be disclosed. Furthermore, as noted in our 
proposed action, the Utah SIP contains only a reference to Utah Code 
section 19-2-104. See 78 FR at 52842 n.5. Thus, even to the extent that 
a general provision requiring promulgation of conflict of interest 
rules can be said to ``address'' the specific disclosure requirements 
in CAA section 128(a)(2), Utah Code section 19-1-201 cannot be used for 
that purpose, as it is not approved into the SIP.
    We turn to the rules in UAC sections R305-9-101 to -106 cited by 
the commenters. These rules have not been submitted to EPA by the State 
of Utah for inclusion in the SIP. If and when they and any other 
provisions are submitted by the State, EPA will evaluate them for 
compliance with section 128 and act accordingly. Until such provisions 
are approved into the SIP, they cannot be relied on to satisfy the 
requirements of section 128 for purposes of an infrastructure SIP 
submission. Thus, it was not necessary for EPA to assess these 
unsubmitted provisions (which also were not cited in the infrastructure 
SIP submittals) in proposing disapproval of Utah's infrastructure SIP 
submissions for element 110(a)(2)(E)(ii).
    Aside from the requirement that provisions to meet section 128 must 
be approved into the SIP, the commenters do not explain how the new 
rules in UAC sections R305-9-101 to -106 would meet the requirements 
for section 128(a)(2) when, for example, the Director, acting alone and 
not as a member of the Board, approves a permit. As explained in our 
notice--and again undisputed by the commenters--the Board no longer has 
authority to approve permits that the State issues under the Act. By 
their own terms, the disclosure rules promulgated by the Department 
apply only to ``matters before the Board.'' See UAC R305-9-104, -105. 
Because the Board no longer has authority to approve permits, the 
disclosure rules do not apply to permit actions. In those actions, the 
Director acts alone and not as a member of the Board. The rules on 
their face thus do not appear to apply to the Director's decisions on 
permits or to satisfy the requirements of section 128(a)(2) as applied 
to the Director.
    As mentioned above, when the State does submit provisions to meet 
the requirements of section 128, we will act on them. However, the 
comment provides no basis for us to change our proposed disapproval of 
the Utah infrastructure SIPs for element 110(a)(2)(E)(ii) for the 1997 
and 2006 PM2.5 NAAQS.
    Comment: One commenter questioned our approval of Utah's SIP as to 
the October 20, 2010 major source baseline date for the 
PM2.5 increments. The commenter contends that the court 
decision in NRDC v. EPA, 706 F.3d 428 (D.C. Cir. 2013), requires that 
EPA treat PM2.5 in the same manner as PM10 with 
respect to establishing baseline dates. The commenter contends that, 
because the court held that the statutory definition of PM10 
includes PM2.5, EPA must interpret CAA sections 166(f) and

[[Page 63885]]

169(4) as applying the statutory major source baseline date of January 
6, 1975, to the regulation of PM2.5 increments in the same 
manner that it applies to the regulation of PM10.
    Response: EPA does not agree with the commenter's contention, and 
is approving this element of the Utah SIP because it is consistent with 
applicable EPA regulations implementing the CAA. EPA's regulations are 
not altered by the court decision cited by the commenter. As discussed 
in the proposal, the court in NRDC v. EPA addressed whether EPA acted 
appropriately in establishing SIP requirements in the 2007 and 2008 
PM2.5 NAAQS implementation rules via only subpart 1 of Part 
D, title I, of the CAA, which establishes plan requirements for 
nonattainment areas in general, instead of subpart 4 of Part D, which 
establishes additional provisions for particulate matter nonattainment 
areas. The court concluded that because the Act defines the term 
PM10 to include PM2.5, the requirements of 
subpart 4 that pertain to PM10 nonattainment areas also 
apply to PM2.5 nonattainment areas. As subpart 4 pertains 
exclusively to particulate matter nonattainment areas, the court's 
decision does not address the part C PSD program requirements for 
PM2.5, which apply to attainment and unclassifiable areas.
    EPA adopted the PM2.5 increments and the associated 
baseline dates in a 2010 rule that was not before the court in NRDC v. 
EPA. The D.C. Circuit issued a separate decision on January 22, 2013, 
in Sierra Club v. EPA, 705 F.3d 458, that vacated the SILs and SMC for 
PM2.5 that were also promulgated by EPA in the 2010 rule. 
Because no party raised the issue in that case, the January 2013 
decision did not address any of the PM2.5 increment 
provisions (including the baseline dates) adopted in that rule.
    The PM2.5 increments and baseline dates promulgated in 
the 2010 rule thus remain in effect and are unchanged by recent court 
decisions. EPA established the PM2.5 increments as 
additional increments under section 166(a) of the CAA rather than 
substitute increments under section 166(f). See 75 FR 64864, 64871-2 
(Oct. 20, 2010). A complete discussion of how the rule implements the 
requirements of the CAA is contained in the preamble to the 2010 rule. 
An opportunity to raise concerns with EPA's decision to set the 
PM2.5 major source baseline date in 2010 was available 
during the comment period on the 2010 rulemaking and court challenge 
that produced the January 2013 decision. EPA may not rewrite those 
rules in the context of this action, but rather EPA is bound to apply 
them in their present form to the Utah SIP submission.
    The 2010 rule amended EPA's regulations at 40 CFR 51.166, which 
establishes the minimum requirements that a state must meet in order to 
obtain EPA approval of the PSD program elements of a state 
implementation plan. Section 51.166(b) specifies that ``[a]ll state 
plans shall use the following definitions for the purposes of this 
section.'' Within this provision, section 51.166(b)(14)(i) establishes 
separate and distinct major source baseline dates for PM10 
and PM2.5. Furthermore, the definition of minor source 
baseline date in section 51.166(b)(14)(ii) contains separate and 
distinct trigger dates for PM10 and PM2.5. Utah's 
plan is approvable because it uses these definitions and thus meets the 
criteria EPA has established by rule as sufficient to satisfy the 
relevant requirements of title I, Part C of the CAA. The Utah plan 
incorporates by reference the definitions of major source baseline date 
and minor source baseline date in section 40 CFR 52.21(b)(14), which 
are the same as those in section 51.166(b)(14).

III. Final Action

    EPA is approving Utah's April 17, 2008 and March 14, 2012 
submissions with respect to the following CAA section 110(a)(2) 
infrastructure elements for the 1997 and 2006 PM2.5 NAAQS: 
(A), (B), (C) with respect to minor NSR and PSD requirements, 
(D)(i)(II) with respect to PSD requirements, (E)(i), (E)(iii), (F), 
(G), (H), (J), (K), (L), and (M).
    EPA disapproves Utah's submissions with respect to the section 
110(a)(2)(E)(ii) infrastructure element for the 1997 and 2006 
PM2.5 NAAQS.
    We are approving the following portions of the State's March 14, 
2012 submission to address the 2008 PM2.5 NSR Implementation 
Rule and the 2010 PM2.5 Increment Rule; specifically we 
approve the adoption of the text of 40 CFR 52.21, paragraphs 
(b)(14)(i),(ii),(iii); (b)(15)(i),(ii); (b)(23)(i); (b)(50) and 
paragraph (c) as they existed on July 1, 2011.
    EPA is taking no action on infrastructure elements (D)(i)(I), 
interstate transport of pollutants which contribute significantly to 
nonattainment in, or interfere with maintenance by, any other state, 
and (D)(i)(II), with respect to visibility requirements for the 2006 
PM2.5 NAAQS as EPA is acting separately on these elements. 
Finally, EPA is correcting an erroneous statement made in a previous 
action regarding requirements for state judicial review of PSD permits.

IV. Statutory and Executive Order Reviews

    Under the Clean Air Act, the Administrator is required to approve a 
SIP submission that complies with the provisions of the Act and 
applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). 
Thus, in reviewing SIP submissions, EPA's role is to approve state 
choices, provided that they meet the criteria of the Clean Air Act. 
Accordingly, this action merely approves some state law as meeting 
Federal requirements and disapproves other state law as not meeting 
Federal requirements; it does not impose additional requirements beyond 
those imposed by state law. For that reason, this 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 (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 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 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000), 
because the SIP is not approved to apply in Indian country

[[Page 63886]]

located in the state, and EPA notes that it will not impose substantial 
direct costs on tribal governments or preempt tribal law.
    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. EPA will submit a report containing this action and 
other required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the United States prior 
to publication of the rule in the Federal Register. A major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2).
    Under section 307(b)(1) of the Clean Air Act, petitions for 
judicial review of this action must be filed in the United States Court 
of Appeals for the appropriate circuit by December 24, 2013. Filing a 
petition for reconsideration by the Administrator of this final rule 
does not affect the finality of this action for the purposes of 
judicial review nor does it extend the time within which a petition for 
judicial review may be filed, and shall not postpone the effectiveness 
of such rule or action. This action may not be challenged later in 
proceedings to enforce its requirements. (See section 307(b)(2).)

Sec.  52.2346  Significant deterioration of air quality.

* * * * *
    (d) On March 14, 2012 the State of Utah submitted revisions to the 
State Implementation Plan that incorporated the required elements of 
the 2008 PM2.5 NSR Implementation Rule and the 2010 
PM2.5 Increment Rule. The following provisions are approved 
into the State Implementation Plan.
    (1) Major source baseline date means:
    (i) In the case of PM10 and sulfur dioxide, January 6, 
1975;
    (ii) In the case of nitrogen dioxide, February 8, 1988; and
    (iii) In the case of PM2.5, October 20, 2010.
    (2) Minor source baseline date means the earliest date after the 
trigger date on which a major stationary source or a major modification 
subject to 40 CFR 52.21 or to regulations approved pursuant to 40 CFR 
51.166 submits a complete application under the relevant regulations. 
The trigger date is:
    (i) In the case of PM10 and sulfur dioxide, August 7, 
1977;
    (ii) In the case of nitrogen dioxide, February 8, 1988; and
    (iii) In the case of PM2.5, October 20, 2011.
    (3) The baseline date is established for each pollutant for which 
increments or other equivalent measures have been established if:
    (i) The area in which the proposed source or modification would 
construct is designated as attainment or unclassifiable under section 
107(d)(1)(A)(ii) or (iii) of the Act for the pollutant on the date of 
its complete application under 40 CFR 52.21 or under regulations 
approved pursuant to 40 CFR 51.166; and
    (ii) In the case of a major stationary source, the pollutant would 
be emitted in significant amounts, or in the case of a major 
modification, there would be a significant net emissions increase of 
the pollutant.
    (4) Baseline area means any intrastate area (and every part 
thereof) designated as attainment or unclassifiable under section 
107(d)(1)(A)(ii) or (iii) of the Act in which the major source or major 
modification establishing the minor source baseline date would 
construct or would have an air quality impact for the pollutant for 
which the baseline date is established, as follows: equal to or greater 
than 1 [mu]g/m\3\ (annual average) for SO2, NO2, 
or PM10; or equal or greater than 0.3 [mu]g/m\3\ (annual 
average) for PM2.5.
    (5) Area redesignations under section 107(d)(1)(A)(ii) or (iii) of 
the Act cannot intersect or be smaller than the area of impact of any 
major stationary source or major modification which:
    (i) Establishes a minor source baseline date; or
    (ii) Is subject to 40 CFR 52.21 or [Utah Administrative Code (UAC)] 
R307-405 and would be constructed in the same state as the state 
proposing the redesignation.
    (6) Significant means, in reference to a net emissions increase or 
the potential of a source to emit any of the following pollutants, a 
rate of emissions that would equal or exceed any of the following 
rates:
    (i) Carbon monoxide: 100 tons per year (tpy).
    (ii) Nitrogen oxides: 40 tpy.
    (iii) Sulfur dioxide: 40 tpy.
    (iv) Particulate matter: 25 tpy of particulate matter emissions.
    (v) PM10: 15 tpy.
    (vi) PM2.5: 10 tpy of direct PM2.5 emissions; 
40 tpy of sulfur dioxide emissions; 40 tpy of nitrogen oxide emissions 
unless demonstrated not to be a PM2.5 precursor under 40 CFR 
52.21(b)(50).
    (vii) Ozone: 40 tpy of volatile organic compounds or nitrogen 
oxides.
    (viii) Lead: 0.6 tpy.
    (ix) Fluorides: 3 tpy.
    (x) Sulfuric acid mist: 7 tpy.
    (xi) Hydrogen sulfide (H2S): 10 tpy.
    (xii) Total reduced sulfur (including H2S): 10 tpy.
    (xiii) Reduced sulfur compounds (including H2S): 10 tpy.
    (xiv) Municipal waste combustor organics (measured as total tetra-
through octa-chlorinated diebenzo-p-dioxins and dibenzofurans): 3.2 x 
10\M6\ megagrams per year (3.5 x 10\M6\ tons per year).
    (xv) Municipal waste combustor metals (measured as particulate 
matter): 14 megagrams per year (15 tons per year).
    (xvi) Municipal waste combustor acid gases (measured as sulfur 
dioxide and hydrogen chloride): 36 megagrams per year (40 tons per 
year).
    (xvii) Municipal solid waste landfills emissions (measured as 
nonmethane organic compounds): 45 megagrams per year (50 tons per 
year).
    (7) Regulated NSR pollutant, for purposes of this section means the 
following:
    (i) Any pollutant for which a national ambient air quality standard 
has been promulgated and any pollutant identified under 40 CFR 
52.21(b)(50)(i) as a constituent or precursor for such pollutant. 
Precursors identified by the EPA Administrator for purposes of NSR are 
the following:
    (A) Volatile organic compounds and nitrogen oxides are precursors 
to ozone

[[Page 63887]]

in all attainment and unclassifiable areas.
    (B) Sulfur dioxide is a precursor to PM2.5 in all 
attainment and unclassifiable areas.
    (C) Nitrogen oxides are presumed to be precursors to 
PM2.5 in all attainment and unclassifiable areas, unless the 
State demonstrates to the EPA Administrator's satisfaction or EPA 
demonstrates that emissions of nitrogen oxides from sources in a 
specific area are not a significant contributor to that area's ambient 
PM2.5 concentrations.
    (D) Volatile organic compounds are presumed not to be precursors to 
PM2.5 in any attainment or unclassifiable area, unless the 
State demonstrates to the EPA Administrator's satisfaction or EPA 
demonstrates that emissions of volatile organic compounds from sources 
in a specific area are a significant contributor to that area's ambient 
PM2.5 concentrations.
    (ii) Any pollutant that is subject to any standard promulgated 
under section 111 of the Act;
    (iii) Any Class I or II substance subject to a standard promulgated 
under or established by title VI of the Act;
    (iv) Any pollutant that otherwise is subject to regulation under 
the Act.
    (v) Notwithstanding 40 CFR 52.21(b)(50)(i) through (iv), the term 
regulated NSR pollutant shall not include any or all hazardous air 
pollutant either listed in section 112 of the Act, or added to the list 
pursuant to section 112(b)(2) of the Act, and which have not been 
delisted pursuant to section 122(b)(3) of the Act, unless the listed 
hazardous air pollutant is also regulated as a constituent or precursor 
of a general pollutant listed under section 108 of the Act.
    (vi) Participate matter (PM) emissions, PM2.5 emissions 
and PM10 emissions shall include gaseous emissions from a 
source or activity which condense to form particulate matter at ambient 
temperatures. On or after January 1, 2011 (or any earlier date 
established in the upcoming rulemaking codifying test methods), such 
condensable particulate matter shall be accounted for in applicability 
determinations and in establishing emissions limitations for PM, 
PM2.5 and PM10 in PSD permits. Compliance with 
emissions limitations for PM, PM2.5 and PM10 
issued prior to this date shall not be based on condensable particular 
matter unless required by the terms and conditions of the permit or the 
applicable implementation plan. Applicability determinations made prior 
to this date without accounting for condensable particular matter shall 
not be considered in violation of this section unless the applicable 
implementation plan required condensable particular matter to be 
included.
    (8) Ambient air increments. (i) In areas designated as Class I, II, 
or III, increases in pollutant concentration over the baseline 
concentration shall be limited to the following:
