The revisions submitted November 8, 1995, February 12, 1996, November 20, 1996, and May 15, 1997, deleted volatile methyl siloxanes, parachlorobenzotrifluoride (PCBTF), acetone, perchloroethylene (PERC), HFC 43-10mee, HCFC 225ca and HCFC 225cb from the definition of VOCs. The June 10, 1998 submittal incorporated the deletion of 16 more pollutants from the federal list that were determined to have a negligible contribution to tropospheric ozone formation; the compounds are: HFC-32, HFC-161, HFC-236fa, HFC-245ca, HFC-245ea, HFC-245eb, HFC-245fa, HFC-236ea, HFC-365mfc, HCFC-31, HCFC-123a, HCFC-151a, C4F9OCH3, (CF3)2CFCF2OCH3, C4F9OC2H5, and (CF3)2CFCF2OC2H5 (compound names only are listed here, refer to 62 FR 44901, August 25, 1997 for the chemical name and 62 FR 44903, August 25, 1997 for the complete list of exempted VOCs). A second February 12, 1996 Governor's submittal contained minor wording revisions which were made to UACR R307-6-1 regarding VOC emissions from air strippers and soil venting operations. The revision submitted November 20, 1996 also repealed UACR R307-14-8 which had addressed requirements for perchloroethylene dry cleaning plants located in ozone nonattainment and maintenance areas.

EPA returned the portions of these plans with a letter to the Governor on January 29, 1999. A nonsubstantive change was made in this section as a result of the revision which moves section 4.13.3 D to section 4.13.3.E; this change was also approved by EPA.

On March 22, 2007, the Governor also submitted revisions to associated rules: UAC R307-101-2, R307-110-13, R307-320, R307-325, R307-326, R307-327, R307-328, R307-335, R307-340, R307-341, and R307-342. EPA is approving the maintenance plan, except for the following aspects, which EPA is disapproving: those contingency measures listed in section 6.d of the State's maintenance plan that are voluntary in nature, which consist of: “Alert Day Enhancements,” “Heavy Equipment Emission Control Program,” “Reduce Emissions of VOCs” (to the extent the State would adopt and implement the measure as a voluntary commitment rather than a regulatory measure), “Identification of High-Polluting Vehicles,” and “Other VOC or NOX emissions control measures as appropriate” (to the extent such measures would be voluntary); the contingency measure listed in section 6.d of the State's maintenance plan as “Establish an Offset Ratio for NOX;” the State's proposal in section 5.a.(3)(b)of the maintenance plan to remove from the SIP the VOC RACT approval orders for Hill Air Force Base; the State's proposal in section 5.b.(1) of the maintenance plan to remove from the SIP the NOX RACT limits for the PacifiCorp Gadsby Power Plant; and section 5.g of the maintenance plan, which indicates that the employer-based trip reduction program is included as part of the plan. EPA is approving the revisions to UAC R307-110-13, which incorporates the maintenance plan into Utah's rules, but only to the extent we are approving the 1997 8-hour ozone maintenance plan.

(75) On September 15, 2006, the Governor submitted revisions to the Utah State Implementation Plan (SIP) permitting rules. The September 15, 2006 submittal contains new, amended and renumbered rules in Utah Administrative Code (UAC) Title R-307 that pertain to the issuance of Utah air quality permits. EPA is approving the following rules or parts of rules from the September 15, 2006 submittal: R307-401-1 through 6; R307-401-8; R307-401-9 (except for paragraph (b) and the portions of paragraph (c) that reference paragraph (b)); R307-401-10 through 11; R307-401-13; R307-401-17 through 20; and R307-410-1 through 4. EPA is disapproving the following rules or parts of rules from the September 15, 2006 submittal: R307-401-7; R307-401-9(b) and the portions of 9(c) that reference (9)(b); R307-401-12; and R307-410-5. EPA is limitedly approving and limitedly disapproving R307-410-6 from the September 15, 2006 submittal—this means EPA is approving this rule because it will strengthen the SIP but is simultaneously disapproving it because it does not fully comply with applicable requirements. EPA is not acting on the revisions to UAC R307-101-2 because the revisions have been superseded by later revisions to the rule, which EPA approved at §52.2320(c)(67) (see 73 FR 51222). EPA is not acting on R307-401-14 through 16 because EPA previously acted on such provisions (notice of final rulemaking signed October 19, 2012).
