II. Background

    On September 20, 1999, the State of Utah submitted a renumbering 
and recodification of its Utah Administrative Code (UAC) rules within 
the Utah SIP. EPA took final action to approve portions of this 
submittal on February 13, 2006 (71 FR 7670). In that action EPA 
approved the recodification of R307-413-7 (Exemption from Notice of 
Intent Requirements for Used Oil Burned for Energy Recovery, previously 
found under R307-7-2 and 3). On September 15, 2006, the State of Utah 
again submitted a renumbering and recodification of its UAC rules 
within the Utah SIP which renumbered R307-413-7 to R307-401-14 (Used 
Oil Burned for Energy Recovery). We are proposing to approve this 
renumbering in this action.
    On April 17, 2008, the State of Utah submitted a revision to R307-
401-14 which changed the definition of ``Boiler.'' We are proposing to 
approve this definition change in this action.
    On October 1, 1990, R307-6 (De minimis Emissions from Air Strippers 
and Soil Venting Projects) was approved into the Utah SIP. On August 
14, 1998, EPA approved revisions to R307-6 (63 FR 43624). On January 8, 
1999, Utah submitted substantive revisions to R307-6, which also 
renumbered R307-6 to R307-413-8 and R307-413-9. EPA did not act on this 
submittal. On September 15, 2006, Utah submitted revisions which moved 
R307-413-8 and R307-413-9 to R307-401-15 (Air Strippers and Soil 
Venting Projects) and R307-401-16 (De minimis Emissions from Soil 
Aeration Projects). Utah's January 8, 1999, submittal is superceded by 
the September 15, 2006, submittal. EPA is proposing to conditionally 
approve R307-401-15 and approve R307-401-16 as submitted on September 
15, 2006, in this action.
    All other portions of the September 15, 2006, submittal not 
addressed in this action will be addressed at a later date.

III. What Authorities Apply to EPA's Proposed Action

    Section 110(l) of the CAA states, ``Each revision to an 
implementation plan submitted by a State under this Act shall be 
adopted by such State after reasonable notice and public hearing. The 
Administrator shall not approve a revision to a plan if the revision 
would interfere with any applicable requirement concerning attainment 
and reasonable further progress (as defined in section 171), or any 
other applicable requirement of this Act.''
    The states' obligation to comply with each of the National Ambient 
Air Quality Standards (NAAQS) is considered as ``any applicable 
requirement(s) concerning attainment.'' A demonstration is necessary to 
show that this revision will not interfere with attainment or 
maintenance of the NAAQS, including those for ozone, particulate 
matter, carbon monoxide, sulfur dioxide, lead, nitrogen oxides or any 
other requirement of the Act.
    The CAA at section 110(a)(2)(C) requires states to include a minor 
New Source Review (NSR) program in their SIP to regulate modifications 
and new construction of stationary sources within the area as necessary 
to assure the NAAQS are achieved. EPA's implementing regulations at 40 
CFR 51.160-164 are intended to ensure that new source growth is 
consistent with maintenance of the NAAQS and 40 CFR 51.160(e) requires 
states to identify types and sizes of facilities which will be subject 
to review under their minor NSR program. For sources identified under 
40 CFR 51.160(e), section 51.160(a) requires that the SIP include 
legally enforceable procedures that enable a state or local agency to 
determine whether construction or modification of a facility, building, 
structure or installation, or combination of these will result in a 
violation of applicable portions of the control strategy; or 
interference with attainment or maintenance of a national standard in 
the state in which the proposed source (or modification) is located or 
in a

[[Page 37861]]

neighboring state. Section 110(i) of the CAA specifically precludes 
states from changing the requirements of the SIP except through SIP 
revisions approved by EPA. SIP revisions will be approved by EPA only 
if they meet all requirements of section 110 of the CAA and the 
implementing regulations at 40 CFR part 51. See CAA section 110(l); 40 
CFR 51.104.
    EPA recognizes that, under the applicable Federal regulations, 
states have broad discretion to determine the scope of their minor NSR 
programs as needed to attain and maintain the NAAQS. The states have 
significant discretion to tailor minor NSR requirements that are 
consistent with the requirements of 40 CFR part 51. States may also 
provide a rationale for why the rules are at least as stringent as the 
40 CFR part 51 requirements where the revisions are different from 
those in 40 CFR part 51. For example, states may exempt from minor new 
source review certain categories of changes based on de minimis or 
administrative necessity grounds in accordance with the criteria set 
out in Alabama Power Co. v. Costle, 636 F.2d 323, 360-361 (D.C. Cir. 
1979). De minimis sources are presumed not to have an impact and their 
emissions would not prevent or interfere with attainment of the NAAQS, 
even within nonattainment areas.
    Since there are no ambient air quality standards for air toxics, 
the area's compliance with any applicable maximum achievable control 
technology (MACT) standards, as well as any Federal mobile source 
control requirements under CAA sections 112 or 202(l) would constitute 
an acceptable demonstration of noninterference for air toxics. A 
revision to the SIP cannot interfere with any federally mandated 
program such as a MACT standard (or related section 112 requirements).

IV. EPA's Analysis and Proposed Action on SIP Revisions

    In this proposed rulemaking, we are proposing to approve the 
renumbering of R307-413-7 to R307-401-14 (Used Oil Burned for Energy 
Recovery) as submitted by the State of Utah on September 15, 2006, 
because this provision had been previously approved into the Utah SIP 
(71 FR 7670) and the revision does not contain substantive changes to 
the rule. We are also clarifying that R307-401-14(3) refers to the 
owner or operator of a boiler as described in R307-401-14(1).
    We are proposing to approve changes to the definition of ``Boiler'' 
in R307-401-14(1) as submitted by the State of Utah on April 17, 2008, 
in this action. The current federally approved definition of ``Boiler'' 
in R307-413-7 references Utah's solid and hazardous waste definition of 
``Boiler'' in R315-1-1 as it was defined in 40 CFR 260.10, as amended 
on July 1, 2002. Utah's current federally approved version of R315-1-1 
incorporates by reference 40 CFR 260.10, as amended on July 1, 2008. 
Since there is no substantive difference between 40 CFR 260.10, as 
amended on July 1, 2002, and 40 CFR 260.10, as amended on July 1, 2008, 
we are proposing to approve this definition change in R307-401-14.
    We are proposing to conditionally approve R307-401-15 and approve 
R307-401-16 as submitted on September 15, 2006, in this action. We are 
proposing to conditionally approve R307-401-15 because R307-401-15(3) 
allows for ``test or monitoring method approved by the executive 
secretary,'' which is director's discretion. Utah submitted a letter to 
EPA on February 24, 2012, committing to revise R307-401-15(3) to remove 
the executive secretary's discretion to approve alternate test or 
monitoring methods (see docket). Utah must submit a SIP revision to 
change or remove this language not later than one year after the date 
of final publication of this rulemaking. If, however, Utah does not 
submit such a revision within this timeframe, EPA's conditional 
approval of R307-401-15(3) will revert to a disapproval.
    R307-401-15 and R307-401-16 allows all air stripper, soil venting 
and soil aeration projects to be exempt from notice of intent and 
approval order requirements if the estimated actual air emissions from 
volatile organic compounds from a given project are less than 5 tons 
per year (R307-401-9(1)(a)) and the level of any one hazardous air 
pollutant (HAP) or combination of HAPs is less than the levels listed 
in R307-410-4(1)(d) (Toxic Screening Levels and Averaging Periods). EPA 
has approved similar de minimis thresholds for criteria pollutants in 
past rulemakings: The State of Idaho's permit to construct regulations, 
which were approved final on January 16, 2003 (68 FR 2217); and the 
State of Montana's exclusion for de minimis changes, which were 
approved final on February 13, 2012 (77 FR 7531). R307-401-15 and R307-
401-16 contain provisions which are smaller in nature and scope than 
the previously approved rulemakings, as they generally only apply to 
the remediation of underground storage tanks. EPA finds the revisions 
would not interfere with any applicable requirement concerning 
attainment of the NAAQS, rate of progress and reasonable further 
progress (as defined in section 171), or any other applicable 
requirement of this Act.
    A review of air stripper, soil venting and soil aeration projects 
from 2008-2010 which were exempted from notice of intent and approval 
order requirements under R307-401-15 and R307-401-16 show negligible 
criteria pollutant emissions (see docket). In addition, data from the 
Utah leaking underground storage tank program shows a significant 
decrease in the number of new cleanups initiated over the last 10 years 
(see docket). These provisions meet the requirements of 40 CFR 51.160 
because they require prior written approval (R307-401-15(2), R307-401-
16(1)) of the State and have testing requirements (R307-401-15(3)) to 
ensure that exempted projects do not exceed the de minimis thresholds 
as described in R307-401-9.

V. Summary of Proposed Actions

    Based on the above discussion, EPA finds that the revisions are 
consistent with all CAA requirements. We are proposing to approve the 
renumbering of R307-413-7 to R307-401-14 (Used Oil Burned for Energy 
Recovery) as submitted by the State of Utah on September 15, 2006; 
changes to the definition of ``Boiler'' in R307-401-14(1), as submitted 
by the State of Utah on April 17, 2008; and conditionally approve R307-
401-15 and approve R307-401-16 as submitted on September 15, 2006.

VI. 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 proposed action merely approves state law as meeting 
Federal requirements and 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

[[Page 37862]]

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 6, 2000), 
because the SIP is not approved to apply in Indian country located in 
the State, and EPA notes that it will not impose substantial direct 
costs on tribal governments or preempt tribal law.
