I. What Action is EPA Taking? 

A. Summary of Final Action 

We are taking final action to approve the renumbering of R307 -413-7 to R307 -401-14 

(Used Oil Fuel Burned for Energy Recovery) as submitted by the State ofUtah on September 15, 

2006; changes to the definition of"Boiler" in R307-401-14(1), as submitted by the State of Utah 

on April17, 2008; and conditionally approve R307-401-15 and approve R307-401-16 as 

submitted on September 15, 2006. 

EPA proposed an action for the above SIP revision submittals on June 25,2012, (77 FR 

37859.) We accepted comments from the public on this proposal from June 26, 2012, until July 

25,2012. EPA received no comments during the public comment period. In the proposed rule, 

we described our basis for the actions identified above. The reader should refer to the proposed 

rule, and sections III and IV of this preamble, for additional information regarding this final 

action. 

EPA reviews a SIP revision submission for its compliance with the Act and EPA 

regulations. We evaluated the submitted SIP revisions for Utah's minor NSR regulations based 

upon the regulations and associated record that have been submitted and are currently before 

EPA. In order for EPA to ensure that Utah has regulations that meet the requirements ofthe 

CAA, the State must demonstrate the regulations are as stringent as the Act and the 

3 
implementing regulations discussed in this notice. For example, EPA must have sufficient 

information to make a finding that the new regulations will ensure protection of the NAAQS, and 

noninterference with the Utah SIP control strategies, as required by section 110(1) ofthe Act. 

II. Background 

On September 20, 1999, the State ofUtah submitted a renumbering and recodification of 

its Utah Administrative Code (UAC) rules within the Utah SIP. EPA took final action to 

approve portions ofthis submittal on February 14,2006 (71 FR 7670). In that action EPA 

approved the recodification ofR307-413-7 (Exemption from Notice oflntent Requirements for 

Used Oil Fuel Burned for Energy Recovery, previously found under R307-7-2 and 3). On 

September 15, 2006, the State ofUtah 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 Fuel 

Burned for Energy Recovery). We are taking final action to approve this renumbering in this 

action. 

On April17, 2008, the State of Utah submitted a revision to R307-401-14 which changed 

the definition of "Boiler." We are taking final action 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 

4 
superceded by the September 15, 2006, submittal. EPA is taking final action 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. 

IV. What are the Grounds for this Approval Action 

In this final rulemaking, we are taking final action to approve the renumbering ofR307-

413-7 to R307-401-14 (Used Oil Fuel 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 taking final action to approve changes to the definition of"Boiler" in R307-401-

14(1) as submitted by the State of Utah on April17, 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 

taking final action to approve this definition change in R307-401-14. 

We are taking final action to conditionally approve R307-401-15 and approve R307-401-

16 as submitted on September 15, 2006, in this action. CAA 110(k)(4) states "The administrator 

may approve a plan revision based on a commitment of the State to adopt specific enforceable 

5 
measures by a date certain, but not later than 1 year after the date of approval of the plan 

revision. Any such conditional approval shall be treated as a disapproval if the state fails to 

comply with such commitment". 

We are taking final action to conditionally approve R307-401-15 because R307-401-

l5(3) allows for a "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 on this rulemaking. If, 

however, Utah does not submit such a revision within this timeframe, EPA's conditional 

approval ofR307-401-15(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 are 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 

6 
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 -40 1-15(2), 

R307-401-16(1)) ofthe 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 Final Actions 

Based on the above discussion, EPA finds that the revisions are consistent with all CAA 

requirements. We are taking final action to approve the renumbering ofR307-413-7 to R307-

401-14 (Used Oil Fuel Burned for Energy Recovery) as submitted by the State ofUtah on 

September 15, 2006; changes to the definition of"Boiler" in R307-401-14(1), as submitted by 

the State ofUtah on April17, 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 ofthe 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 

7 
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 (Public Law 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, April23, 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 

8 
.. 

FR 67249, November 9, 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. 

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 ofthe 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 [insert date 60 

days from date of publication of this document in the Federal Register]. 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).)
