1. General Requirements 8
9
Federal I/M Program requirements: Utah was previously required by Section 182 and 10
Section 187 of the Clean Air Act (CAA) to implement and maintain an Inspection and 11
Maintenance (I/M) program in Davis, Salt Lake, Utah, and Weber counties that met the 12
minimum requirements of 40 Code of Federal Regulation (CFR) Part 51 Subpart S and 13
was at least as effective as the Environmental Protection Agency’s (EPA's) Basic 14
Performance Standard as specified in 40 CFR 51.352. The Basic Performance Standard 15
requirement is no longer applicable as the relevant nonattainment areas in Davis, Salt 16
Lake, Utah, and Weber counties have been redesignated to attainment / maintenance for 17
the carbon monoxide (CO) National Ambient Air Quality Standards (NAAQS) and the 1-18
hour ozone NAAQS. Parts A, B, C, D, and E of Section X, together with the referenced 19
appendices, continue to demonstrate compliance with the 40 CFR Part 51 provisions for 20
Inspection and Maintenance Program Requirements for Davis, Salt Lake, Utah, and 21
Weber counties and produce mobile source emission reductions that are sufficient to 22
demonstrate continued maintenance of the applicable CO and 1-hour ozone NAAQS. In 23
addition, the Cache, Davis, Salt Lake, Utah, and Weber counties' I/M programs are also 24
utilized as a control measure to attain and maintain EPA's particulate NAAQS (PM2.5 and 25
PM10). 26
27
On-Board Diagnostics (OBD) Checks: By January 1, 2002, OBD checks and OBD-28
related repairs are required as a routine component of Utah I/M programs on model year 29
1996 and newer light-duty vehicles and light-duty trucks equipped with certified on-30
board diagnostic systems. The federal performance standard requires repair of 31
malfunctions or system deterioration identified by or affecting OBD systems. 32
33
Utah I/M program history and general authority: The legal authority for Utah's I/M 34
programs, Utah Code Annotated Section 41-6-163.6 1, was enacted during the First 35
Special Session of the Utah Legislature in 1983. I/M programs were initially 36
implemented by Davis and Salt Lake counties in 1984, Utah County in 1986, and Weber 37
County in 1990. 38
39
In 1990, the Legislature enacted Section 41-6-163.7 2 that requires counties with I/M 40
programs use computerized I/M testing equipment, adopt standardized emission 41
standards, and provide for reciprocity. Those requirements were fully implemented by 42
Davis, Salt Lake, and Utah counties on September 1, 1991, and Weber County on 43

1 Renumbered and recodified in 2005 at Utah Code Annotated 41-6a-1642
2 Renumbered and recodified in 2005 at Utah Code Annotated 41-6a-1643

Section X, Part A, page 2
January 1, 1992. 1
2
Section 41-6-163.6 was again amended by the Legislature in 1992 to include vehicles 3
owned and operated by the federal government, federal employees, and students and 4
employees of colleges and universities. The 1992 revision of 41-6-163.6 also established 5
more stringent restrictions for vehicles that qualify for a farm truck exemption. 6
7
Section 41-6-163.6 requires that, if identified as necessary to attain or maintain any 8
NAAQS, a county must create an I/M program that follows the criteria outlined in 9
Section 41-6-163.6. Once a county enacts regulations or ordinances, amendments to 10
Section 19-2-104 in 1992 authorized the Utah Air Quality Board to formally establish 11
those requirements for county I/M programs after obtaining agreement from the affected 12
counties. Section 41-6-163.6 was also amended to allow the counties to subject 13
individual motor vehicles to inspection and maintenance at times other than the annual 14
inspection. 15
16
Section 41-6-163.6 was amended in 1994 to authorize implementation of I/M programs 17
stricter than minimum federal requirements in counties where it is necessary to attain or 18
maintain ambient air quality standards. Section 41-6-163.6 requires preference be given 19
to a decentralized program to the extent that a decentralized program will attain and 20
maintain ambient air quality standards and meet federal requirements. It also requires 21
affected counties and the Air Quality Board to give preference to the most cost-effective 22
means to achieve and maintain the maximum benefit for air quality standards and to meet 23
federal air quality requirements related to motor vehicles. The Legislature indicated 24
preference for a reasonable phase-out period for replacement of air pollution test 25
equipment made obsolete by an I/M program in accordance with applicable federal 26
requirements and if such a phase-out does not otherwise interfere with attainment of 27
ambient air quality standards. 28
29
House Concurrent Resolution No. 9 of the 1994 General Session of the Legislature 30
(H.C.R. 9) was a concurrent resolution of the Legislature and the Governor expressing 31
opposition to the EPA’s position regarding the implementation of enhanced vehicle 32
inspection. Additionally, H.C.R. 9 urged the EPA to recognize the benefits of other 33
vehicle inspection program options and to work with the state to develop workable plans 34
for attaining ambient air quality standards and protecting public health. 35
36
In 1995, the Legislature amended Section 41-6-163.7 to rescind the requirement for I/M 37
program standardization and reciprocity between counties. While advantageous, 38
standardization and reciprocity between I/M counties is no longer required, and each I/M 39
county is free to develop an I/M program that best meets the respective county’s needs. 40
41
In 2002, the Legislature amended Section 41-6-163.7 to allow for inspection every other 42
year for cars that are six years old or newer on January 1 each year. This provision is 43
applicable to the extent allowed under the current state implementation plan for each 44
area. 45
46

Section X, Part A, page 3
In 2005, the Legislature renumbered Section 41-6-163.6 and re-codified it as Section 41-1
6a-1642. The Legislature also amended Section 41-6a-1642 to allow counties with an 2
I/M program to require college students and employees who park a motor vehicle on 3
college or university campus that is not registered in a county subject to emission 4
inspection, to provide proof of compliance with an emission inspection. 5
6
Section 41 6a-1642 was amended in 2008 to provide an exemption for vintage vehicles, 7
which are defined in Section 41-21-1. Section 41 6a-1642 was again amended in 2009 to 8
provide an exemption for custom vehicles, which are defined in Section 41-6a-1507. 9
10
In 2010, the Legislature enacted Section 41-1a-1223 that allows counties with an I/M 11
program to impose a local emissions compliance fee of up to three dollars. This same bill 12
amended Section 41-6a-1642 to require I/M counties that impose the fee to use revenues 13
generated from the fee to establish and enforce an emission inspection and maintenance 14
program. 15
16
Section 41-6a-1642 was amended in 2011 to require I/M counties’ regulations and 17
ordinances to be compliant with the analyzer design and certification requirements 18
contained in the SIP. 19
20
In 2012, the Legislature amended Section 41-6a-1642 to allow a motor vehicle that is less 21
than two years old as of January 1, of any given year, to be exempt from being required 22
to obtain an emission inspection. This provision is applicable to the extent allowed under 23
the current SIP for each area. This bill went into effect on October 1, 2012. In addition, 24
the Legislature also amended Section 41-1a-205 to allow a safety and emissions 25
inspection issued for a motor vehicle during the previous 11 months may be used to 26
satisfy the safety and emissions inspection requirements 3. The effective date of this bill is 27
January 1, 2013. The Legislature also amended Section 41-1a-1223 to allow the counties 28
to collect a $2.25 fee for those vehicles that are registered for a six-month period under 29
Utah Code Annotated 41-1a-215.5. The effective date of this bill is July 1, 2013. 30
31
Section 41-6a-1642 was amended in 2013 to include the date that notice is required and 32
the date the enactment, change, or repeal will take effect if a county legislative body 33
enacts, changes, or repeals the local emissions compliance fee. Section 41-6a-1642 34
provides that for a county required to implement a new vehicle emissions inspection and 35
maintenance program, but for which no current federally approved state implementation 36
plan exists, a vehicle shall be tested at a frequency determined by the county legislative 37
body, in consultation with the Air Quality Board, that is necessary to comply with federal 38
law or attain or maintain any national ambient air quality standard and establishes 39
procedures and notice requirements for a county legislative body to establish or change 40
the frequency of a vehicle emissions inspection and maintenance program. 41
42
In 2017, the Legislature amended Section 41-6a-1642 to allow a county that imposes a 43

3 Utah Code 41-6a-1642(7) states that “the emissions inspection shall be required within the same time limit applicable to a safety inspection
under Section 41-1a-205.”

Section X, Part A, page 4
local emissions compliance fee to use revenue generated from the fee to promote 1
programs to maintain a national ambient air quality standard. At that time, the Legislature 2
also amended 41-6a-1642 to state that vehicles may not be denied registration based 3
solely on the presence of a defeat device covered in the Volkswagen partial consent 4
decrees or an EPA-approved vehicle modification. 5
6
In 2020, the Legislature amended Section 41-1a-1223 to exempt electric motor vehicles 7
from local emissions compliance fees. Section 41-6a-1642 was amended in 2022 to allow 8
a county to investigate and determine if a vehicle owner has provided a false or an 9
improper address to register a vehicle to avoid an emissions inspection and subsequently 10
allows a county to impose a civil penalty. The Legislature also amended Utah Code in 11
2023 to add a definition for restored modified vehicle. This amendment also requires an 12
emissions inspection as a prerequisite to registration of a restored-modified vehicle and 13
prohibits a county emissions program from refusing to perform an emissions test based 14
solely on the status of a vehicle as a restored-modified vehicle. 15
16
Notification of Programmatic Changes: The legislative body of a county identified in 17
Utah Code 41-6a-1642 (1) shall consult with the Director of the Utah Division of Air 18
Quality prior to their public comment process for any amendments to their I/M 19
regulations or ordinances. Consultation should include a written notice describing the 20
proposed changes to the I/M program. 21
22
2. Applicability 23
24
General Applicability: Utah Code Annotated 41-6a-1642 gives authority to each county 25
to implement and manage an I/M program to attain and maintain any NAAQS. Davis, 26
Salt Lake, Utah, and Weber counties were required under Section 182 and 187 of the 27
CAA to implement an I/M program to attain and maintain the ozone and carbon 28
monoxide NAAQS. All of Utah's ozone and carbon monoxide maintenance areas are 29
located in Davis, Salt Lake, Utah, and Weber counties. In addition, a motor vehicle I/M 30
program is a control measure for attaining the particulate matter NAAQS in Cache, 31
Davis, Salt Lake, Utah, and Weber counties. Utah's SIP for I/M is applicable county-32
wide in Cache, Davis, Salt Lake, Utah, and Weber counties. 33
34
3. General Summary 35
Below is a general summary of Utah’s I/M programs. Part B, C, D, E and F of this 36
section of the SIP provide a more specific summary of I/M programs for Cache, Davis, 37
Salt Lake, Utah, and Weber counties. These parts also incorporate the individual county 38
I/M ordinances/regulations and policies that provide for the enforceability of the 39
respective I/M programs. 40
41
Network Type: All Utah I/M programs are comprised of a decentralized, test-and-repair 42
network. 43

Section X, Part A, page 5
1
I/M program funding requirements: Counties with I/M programs allocate funding as 2
needed to comply with the relevant requirements specified in Utah's SIP, the Utah 3
statutes, county ordinances, regulations and policies, and the federal I/M program 4
regulation. Program budgets include funding for resources necessary to adequately 5
manage the programs and those who conduct covert and overt audits, including: 6
• necessary repairs; 7
• assistance and education for inspectors, station owners, and the public; 8
• management for the analysis and reporting of data; 9
• ensuring program compliance by inspectors, stations, and vehicle owners; and 10
• evaluation and upgrades to the programs. 11
12
Funding mechanisms: Utah's I/M programs are funded through several mechanisms 13
including, but not limited to, a fee which is collected at the time of registration by the 14
Utah Tax Commission Division of Motor Vehicles or the county Assessor's Office. Those 15
monies are remitted to the county where the vehicle is registered. The collection of fees 16
for various permitting activities and the selling inspection certificates to inspection 17
stations are the other mechanisms. A fee schedule can be found in an appendix to each 18
county I/M ordinance or regulation. 19
20
Government fleet: Section 41-6a-1642(1)(b) of the Utah Code requires that all vehicles 21
owned or operated in the I/M counties by federal, state, or local government entities 22
comply with the I/M programs. 23
24
Vehicles owned by students and federal employees: Section 41-6a-1642(5) provides a 25
provision that counties may require universities and colleges located in Utah's I/M areas 26
to require proof of compliance with the I/M program for vehicles which are permitted to 27
park on campus regardless of where the vehicle is registered. Vehicles operated by 28
federal employees and operated on a federal installation located within an I/M program 29
area are also subject to the I/M program regardless of where they are registered. Proof of 30
compliance consists of a current vehicle registration in an I/M program area, an I/M 31
certificate of compliance or waiver, or evidence of exempt vehicle status. 32
33
Rental vehicles: All vehicles available for rent or use in an I/M county are subject to the 34
county I/M program. To the extent practicable, all vehicles principally operated in the 35
county are subject to the I/M program. 36
37
Farm truck exemption: Eligibility for the farm truck exemption from the I/M programs is 38
specified in Section 41-6a-1642(4) and must be verified in writing by county I/M 39
program staff. 40
41
Out-of-state exemption: Vehicles registered in an I/M county but operated out-of-state 42
are eligible for an exemption. The owner must receive a deferment from the county prior 43
to a registration being completed. The owner must explain why the vehicle is unavailable 44

Section X, Part A, page 6
for inspection in Utah. Common situations include Utah citizens that are military 1
personnel stationed outside of the state, students attending institutions of higher education 2
elsewhere, and people serving religious assignments outside the area. If the temporary 3
address of the owner is located within another I/M program area listed on the back of the 4
form, the owner must submit proof of compliance with that I/M program at the time of, 5
and as a condition precedent to, registration or renewal of registration. The vehicle 6
owner must identify their anticipated date of return to the state and is required to have the 7
vehicle inspected within ten days after the vehicle is back in Utah. 8
9
Motorist Compliance Enforcement Mechanism: The I/M programs are registration-10
enforced on a county-wide basis. A certificate of emissions inspection or a waiver or 11
other evidence that the vehicle is exempt from the I/M program requirements must be 12
presented at the time of, and as a condition precedent to, registration or renewal of 13
registration of a motor vehicle as specified in Section 41-6a-1642(1)(a). Owners of 14
vehicles operated without valid license plates or with expired license plates are subject to 15
ticketing by peace officers at any time. Proof of compliance consists of a current vehicle 16
registration in an I/M program area or an I/M certificate of compliance or waiver, or 17
evidence of exempt vehicle status. 18
19
Valid registration required: A certificate of emissions inspection, a waiver, or other 20
evidence that the vehicle is exempt from the I/M program requirements must be 21
presented at the time of, and as a condition precedent to, registration or renewal of 22
registration of a motor vehicle as specified in Section 41-6a-1642 and 41-1a-203(2)(b). 23
The I/M inspection is required within two months prior to the month the registration 24
renewal is due as specified in Section 41-6a-1642(9). Owners of vehicles operated 25
without valid license plates or with expired license plates are subject to ticketing by peace 26
officers at any time. Registration status is also checked on a random basis at roadblocks 27
and in parking lots at various locations around the state. Per Section 41-1a-402, Utah 28
license plates indicate the expiration date of the registration. Per Section 41-1a-1303.5, it 29
is a Class C misdemeanor for a person to drive or move, or for an owner knowingly to 30
permit to be driven or moved, upon any highway any vehicle of a type that is required to 31
be registered in the state that is not registered in the state. Section 41-1a-1315 specifies 32
that it is a third-degree felony to falsify evidence of title and registration. 33
34
Change of ownership: Vehicle owners are not able to avoid the I/M inspection program 35
by changing ownership of the vehicle. Upon change of vehicle ownership, the vehicle 36
must be re-registered by the new owner. The new owner must present an emissions 37
certificate, waiver, or proof of exemption from the I/M program as a condition precedent 38
to registration 4. The new annual registration and I/M inspection dates for the vehicle will 39
be the date of registration. 40
41
Utah Tax Commission, and County Assessors roles: The Utah Tax Commission Motor 42
Vehicle Division and county assessor deny applications for vehicle registration or 43

4 See Utah Code Section 41-6a-1642 (7) and 41-1a-205(2)(b) and (c)

Section X, Part A, page 7
renewal of registration without submittal of a valid certificate of compliance, waiver, or 1
verified evidence of exemption. Altered or hand-written documents are not accepted. All 2
certificate data is collected by county I/M program auditors and subjected to scrutiny for 3
evidence of any improprieties. 4
5
Database quality assurance: The vehicle registration database is maintained, and quality 6
assured by the Utah Division of Motor Vehicle (DMV). Each county I/M inspection 7
database is maintained, and quality assured by the county I/M program staff. The county 8
I/M program has access to the DMV database and utilizes it for quality assurance 9
purposes. All databases are subject to regular auditing, cross-referencing, and analysis. 10
The databases are also evaluated using data obtained during roadblocks and parking lot 11
surveys. Evidence of program effectiveness may trigger additional joint enforcement 12
activities. 13
14
Oversight provisions: The oversight program includes verification of exempt vehicle 15
status through inspection, data accuracy through automatic and redundant data entry for 16
most data elements, an audit trail for program documentation to ensure control and 17
tracking of enforcement documents, identification, and verification of exemption-18
triggering changes in registration data, and regular audits of I/M inspection records, I/M 19
program databases, and the DMV database. 20
21
Enforcement staff quality assurance: County I/M program auditors and DMV clerks 22
involved in vehicle registration are subject to regular performance audits by their 23
supervisors. All enforcement personnel, direct and indirect, involved in the motorist 24
enforcement program are subject to disciplinary action, additional training, and 25
termination for deviation from procedures. Specific provisions are outlined in the DMV 26
procedures manual which is available upon request. The county I/M audit policy 27
documents are provided in their respective part of this section. 28
29
Quality Control: The I/M counties maintain records regarding inspections, equipment 30
maintenance, and the required quality assurance activities. The I/M counties analyze I/M 31
program data and submit annual reports to the EPA and UDAQ upon request. 32
33
Analyzer data collection: Each county’s I/M analyzer data collection system meets the 34
requirements specified under 40 CFR 51.365. 35
36
Data analysis and reporting- Annual: The I/M counties analyze and submit to EPA and 37
UDAQ an annual report for January through December of the previous year, which 38
includes all the data elements listed in 40 CFR Subpart S 51.366 by July of each year. If 39
a report is required earlier than annually, the counties will accommodate the request. 40
41
General enforcement provisions: The county I/M programs are responsible for 42
enforcement action against incompetent or dishonest stations and inspectors. Each county 43
I/M ordinance or regulation includes a penalty schedule. 44
45

Section X, Part A, page 8
General public information: The I/M counties have comprehensive public education and 1
protection programs, including providing the following strategies for: 2
3
• public education on Utah’s air quality problems; 4
• ways that people can reduce emissions; 5
• the requirements of state and federal law; 6
• the role of motor vehicles in the air quality problems; 7
• the need for and benefits of a vehicle emissions inspection program; 8
• ways to operate and maintain a vehicle in a low-emission conditions; 9
• how to find a qualified repair technician; and 10
• the requirements of the I/M program. 11
12
Information is provided via county websites and direct response to inquiries for 13
information, reports, classes, pamphlets, fairs, school presentations, workshops, news 14
releases, posters, signs, and public meetings. Utah Department of Environmental Quality 15
also provides information on its website about ways to operate and maintain a vehicle in 16
a low-emission condition. 17
18
County I/M technical centers: Each I/M county operates an I/M technical center staffed 19
with trained auditors and capable of performing emissions tests. A major function of the 20
I/M technical centers is to serve as a referee station to resolve conflicts between permitted 21
I/M inspectors, stations, and motorists. Auditors actively protect consumers against fraud 22
and abuse by inspectors, mechanics, and others involved in the I/M program. Complaints 23
received are investigated fully. Auditors advise motorists regarding emissions warranty 24
provisions and assist the owners in obtaining warranty covered repairs for eligible 25
vehicles. The I/M technical centers also provide motorists with information regarding the 26
I/M program, general air pollution issues, and emissions-related vehicle repairs. 27
28
Vehicle inspection report: A Vehicle Inspection Report (VIR) will be issued to the 29
motorist after each vehicle inspection. The VIR includes a public awareness statement 30
about vehicle emissions and lists additional ways that the public can reduce air pollution. 31
The test results are detailed on the VIR. Information about vehicle emissions warranties 32
and the benefits of emissions-related repairs are printed for vehicles that failed the test. If 33
the vehicle fails a retest, information about wavier requirements, application procedures, 34
and the address and telephone number of the applicable I/M technical center are printed 35
on the VIR. 36
37
Reciprocity between County I/M programs: Utah I/M programs are conducting the same 38
test procedures and thereby agreed to recognize the validity of a certificate granted by 39
any Utah I/M program. 40

AUTOMOTIVE INSPECTION AND MAINTENANCE (I/M) PROGRAM 4
PART B 5
DAVIS COUNTY 6
1. Applicability 7
Davis County Inspection and Maintenance (I/M) Program Requirements: The Utah Air Quality 8
Board adopted an ozone maintenance plan for Salt Lake and Davis counties on November 5, 9
1993, to address the 1979 1-hour Ozone National Ambient Air Quality Standard (NAAQS). The 10
plan was reorganized and adopted on January 5, 1995. Revisions to the ozone maintenance plan 11
were adopted by the Board on June 5, 1996, and June 7, 1997. The Environmental Protection 12
Agency (EPA) approved the plan on July 17, 1997 (62 FR 38213, July 17, 1997). The ozone 13
maintenance plan required implementation of an improved I/M program no later than January 1, 14
1998. The ozone maintenance plan established a performance standard that was more stringent 15
than the federal Basic I/M Performance Standard. 16
On July 17, 1997, EPA approved the state’s request to redesignate Salt Lake and Davis counties 17
to attainment for the 1979 1-hour ozone standard. As part of that action, EPA approved the 18
state’s 1-hour ozone maintenance plan (62 FR 38213). On July 18, 1997, EPA promulgated an 8-19
hour ozone NAAQS of 0.08 ppm (62 FR 38894). This standard was intended to replace the 1-20
hour ozone standard. On April 30, 2004, EPA designated areas of the United States for the 1997 21
8-hour ozone standard (69 FR 23857). EPA designated all areas in Utah, including Salt Lake 22
County and Davis County, as unclassifiable/attainment for the 1997 8-hour ozone NAAQS (69 23
FR 23940). 24
On April 30, 2004, EPA revoked the 1979 1-hour ozone NAAQS (69 FR23951, 23996; 40 CFR 25
50.9(b). As part of that rulemaking, EPA established certain requirements to prevent backsliding 26
in the areas that were redesignated to “attainment” but subject to a maintenance plan, as is the 27
case for Salt Lake and Davis County. These requirements are codified at 40 CFR 51.905. In the 28
case of Utah, one of these requirements was to submit a maintenance plan for the 1997 8-hour 29
ozone standard. On March 22, 2007, the Governor of Utah submitted a maintenance plan for the 30
1997 8-hour ozone standard for Salt Lake and Davis County, and associated rule revisions, 31
which included an I/M program as a control measure. This plan was approved by EPA on 32
September 26, 2013 (78 FR 59242). 33
On October 26, 2015, the EPA promulgated a revision to the primary NAAQS for ground level 34
ozone (80 FR 65292), lowering the standard to 0.070 ppm for the 4th highest daily 8-hour 35
concentration. Davis County was designated as a “marginal” nonattainment area for the 2015 8-36
hour ozone standard effective August 3, 2018 (83 FR 25776, June 4, 2018). 37

Section X Part B, Page 2

On October 7, 2022, the EPA finalized the reclassification of the Northern Wasatch Front 1
nonattainment area, including Davis County, from marginal to moderate status for the 2015 2
standard. The reclassification to moderate status became effective on November 7, 2022 (87 FR 3
60897). With this redesignation to moderate nonattainment, Davis County is required by 4
Sections 182 and 187 of the CAA to implement and maintain an I/M program in Davis County 5
that met the minimum requirements of 40 CFR Part 51 Subpart S and that was at least as 6
effective as the EPA's Basic Performance Standard as specified in 40 CFR 51.352. Parts A and B 7
of Section X, together with the referenced appendices, demonstrate compliance with the CAA 8
and 40 CFR Part 51 provisions for Basic I/M Performance Program Requirements for Davis 9
County. In addition, the Davis County I/M program is a control measure included in the Salt 10
Lake City 24-hour particulate Serious SIP submitted to EPA on February 15, 2019. 11
2. Summary of Davis County I/M Program 12
13
Below is a summary of Davis County’s I/M program. Section X, Part D Appendix 1 contain the 14
essential documents for Davis County’s I/M program. 15
16
Network Type: Davis County’s I/M program is a decentralized, test-and-repair network. 17
18
Test Convenience: There are approximately 140 permitted I/M stations within Davis 19
County. Specific operating hours are not specified by the county. Some stations that test 20
and/or service only one type of vehicle are permitted. There are also government and 21
private fleet permitted stations that are not open to the public. 22
23
Subject Fleet: All model year 1968 and newer vehicles registered or principally-operated 24
in Davis County, are subject to the I/M program except for exempt vehicles. 25
26
Test Frequency: Vehicles less than two years old as of January 1 on any given year are 27
exempt from an emissions inspection. Vehicles two years old and less than six years old 28
as of January 1 on any given year, are inspected every other year as per Utah Code 41-6a-29
1642(6). All vehicles six years or older as of January 1 on any given year, are inspected 30
annually. 31
32
Station/Inspector Audits: Davis County’s I/M program will regularly audit all permitted 33
I/M inspectors and stations to ensure compliance with county I/M ordinance and policies. 34
Particular attention will be given to identifying and correcting any fraud or incompetence 35
with respect to vehicle emissions inspections. Compliance with recordkeeping, document 36
security, analyzer maintenance, and program security requirements will be scrutinized. 37
Davis County I/M program will have an active covert compliance program to minimize 38
potential fraudulent testing. 39
40

Section X Part B, Page 3

Waivers: Davis County’s I/M program may issue waivers under limited circumstances. 1
The wavier procedure can be found in Davis County’s I/M ordinance provided in 2
Appendix 1. Davis County will take corrective action, as needed, to maintain a maximum 3
waiver rate of 1% of the initially failed vehicles, or the Utah Air Quality Board will 4
revise the SIP and emission reductions claimed based on the actual waiver rate. The 5
conditions for issuing waivers are specified in Davis County’s I/M ordinance and meet 6
the minimum waiver issuance criteria specified in 40 CFR Subparts 51.360. 7
8
Test Equipment: Specifications for Davis County’s emission analyzer and its I/M test 9
procedures, standards, and analyzers are provided in Davis County’s I/M ordinance 10
provided in Appendix 1. Test equipment and procedures were developed according to 11
good engineering practices to ensure test accuracy. Analyzer calibration specifications 12
and emissions test procedures meet the minimum standards established in Appendix A of 13
the EPA's I/M Guidance Program Requirements, 40 CFR Part 51 Subpart S. 14

FROM: David Beatty, Operating Permit Section Manager

DATE: January 23, 2024

SUBJECT: PROPOSE FOR FINAL ADOPTION: Amendment to R307-415. Permits: Operating
Permit Requirements.
______________________________________________________________________________________

The Environmental Protection Agency modified 40 CFR 70, published in the Federal Register / Vol. 88,
No. 139 / Friday, July 21, 2023 / Rules and Regulations, with a rule effective date of August 21, 2023. The
rule change removed Section 40 CFR 70.6(g). Emergency provision.

Subsection R307-415-6(g) was established under 40 CFR 70, and therefore to continue to be in alignment
with the federal rule, the Division of Air Quality (UDAQ) is proposing to remove Subsection R307-415-
6(g) from Rule R307-415.

Additionally, these provisions are included in Section I of each issued Title V permit; however, the
amended rule allows for the individual permits to be changed over time as each permit is modified or
renewed. After this rule amendment becomes effective, UDAQ will remove Subsection 6(g) from each
issued Title V permit going forward.

A public comment period was held from November 15 through December 15, 2023, and no public
comments were received during the comment period.

Recommendation: Staff recommends the Board approve the proposed amendment to R307- 415.

R307-415. Permits: Operating Permit Requirements. 2
R307-415-1. Purpose. 3
Title V of the Clean Air Act (the Act) requires states to develop and implement a comprehensive air 4
quality permitting program. Title V of the Act does not impose new substantive requirements. Title V does 5
require that sources subject to R307-415 pay a fee and obtain a renewable operating permit that clarifies, in a 6
single document, which requirements apply to a source and assures the source's compliance with those 7
requirements. The purpose of R307-415 is to establish the procedures and elements of such a program. 8

(c) Any source, including an area source, subject to a standard or other requirement under Section 19
112 of the Act, Hazardous Air Pollutants, except that a source is not required to obtain a permit solely 20
because it is subject to regulations or requirements under Section 112(r) of the Act, Prevention of Accidental 21
Releases; 22
(d) Any Title IV affected source. 23
(2) Exemptions. 24
(a) All source categories that would be required to obtain an operating permit solely because they 25
are subject to 40 CFR Part 60, Subpart AAA - Standards of Performance for New Residential Wood Heaters, 26
are exempted from the requirement to obtain a permit. 27
(b) All source categories that would be required to obtain an operating permit solely because they 28
are subject to 40 CFR Part 61, Subpart M - National Emission Standard for Hazardous Air Pollutants for 29
Asbestos, Section 61.145, Standard for Demolition and Renovation, are exempted from the requirement to 30
obtain a permit. For Part 70 sources, demolition and renovation activities within the source under 40 CFR 31
61.145 shall be treated as a separate source for the purpose of R307-415. 32
(c) An area source subject to a regulation under Section 111 or 112 of the Act (42 U.S.C. 7411 or 33
7412) promulgated after July 21, 1992 is exempt from the obligation to obtain a Part 70 permit if: 34
(i) the regulation specifically exempts the area source category from the obligation to obtain a Part 35
70 permit, and 36
(ii) the source is not required to obtain a permit under R307-415-4(1) for a reason other than its 37
status as an area source under the Section 111 or 112 regulation containing the exemption. 38
(3) Emissions units and Part 70 sources. 39
(a) For major sources, the director shall include in the permit all applicable requirements for all 40
relevant emissions units in the major source. 41
(b) For any area source subject to the operating permit program under R307-415-4(1), the director 42
shall include in the permit all applicable requirements applicable to emissions units that cause the source to be 43
subject to the operating permit program. 44
(4) Fugitive emissions. Fugitive emissions and fugitive dust from a Part 70 source shall be included 45
in the permit application and the operating permit in the same manner as stack emissions, regardless of 46
whether the source category in question is included in the list of source categories contained in the definition 47
of major source. 48
(5) Control requirements. R307-415 does not establish any new control requirements beyond those 49
established by applicable requirements, but may establish new monitoring, recordkeeping, and reporting 50
requirements. 51
(6) Synthetic minors. An existing source that wishes to avoid designation as a major Part 70 source 52
under R307-415, must obtain federally-enforceable conditions which reduce the potential to emit, as defined 53
in R307-101-2, to less than the level established for a major Part 70 source. Such federally-enforceable 54
Page 5 of 21

conditions may be obtained by applying for and receiving an approval order under R307-401. The approval 1
order shall contain periodic monitoring, recordkeeping, and reporting requirements sufficient to verify 2
continuing compliance with the conditions which would reduce the source's potential to emit. 3
4
R307-415-5a. Permit Applications: Duty to Apply. 5
For each Part 70 source, the owner or operator shall submit a timely and complete permit application. 6
A pre-application conference may be held at the request of a Part 70 source or the director to assist a source in 7
submitting a complete application. 8
(1) Timely application. 9
(a) Except as provided in the transition plan under (3) below, a timely application for a source 10
applying for an operating permit for the first time is one that is submitted within 12 months after the source 11
becomes subject to the permit program. 12
(b) Except as provided in the transition plan under (3) below, any Part 70 source required to meet the 13
requirements under Section 112(g) of the Act, Hazardous Air Pollutant Modifications, or required to receive 14
an approval order to construct a new source or modify an existing source under R307-401, shall file a 15
complete application to obtain an operating permit or permit revision within 12 months after commencing 16
operation of the newly constructed or modified source. Where an existing operating permit would prohibit 17
such construction or change in operation, the source must obtain a permit revision before commencing 18
operation. 19
(c) For purposes of permit renewal, a timely application is one that is submitted by the renewal date 20
established in the permit. The director shall establish a renewal date for each permit that is at least six months 21
and not greater than 18 months prior to the date of permit expiration. A source may submit a permit 22
application early for any reason, including timing of other application requirements. 23
(2) Complete application. 24
(a) To be deemed complete, an application must provide all information sufficient to evaluate the 25
subject source and its application and to determine all applicable requirements pursuant to R307-415-5c. 26
Applications for permit revision need supply such information only if it is related to the proposed change. A 27
responsible official shall certify the submitted information consistent with R307-415-5d. 28
(b) Unless the director notifies the source in writing within 60 days of receipt of the application that 29
an application is not complete, such application shall be deemed to be complete. A completeness 30
determination shall not be required for minor permit modifications. If, while processing an application that 31
has been determined or deemed to be complete, the director determines that additional information is 32
necessary to evaluate or take final action on that application, the director may request such information in 33
writing and set a reasonable deadline for a response. The source's ability to operate without a permit, as set 34
forth in R307-415-7b(2), shall be in effect from the date the application is determined or deemed to be 35
complete until the final permit is issued, provided that the applicant submits any requested additional 36
information by the deadline specified in writing by the director. 37
(3) Transition Plan. A timely application under the transition plan is an application that is submitted 38
according to the following schedule: 39
(a) All Title IV affected sources shall submit an operating permit application as well as an acid rain 40
permit application in accordance with the date required by 40 CFR Part 72 effective April 11, 1995, Subpart 41
C-Acid Rain Permit Applications; 42
(b) All major Part 70 sources operating as of July 10, 1995, except those described in (a) above, and 43
all solid waste incineration units operating as of July 10, 1995, that are required to obtain an operating permit 44
pursuant to 42 U.S.C. Sec. 7429(e) shall submit a permit application by October 10, 1995. 45
(c) Area sources. 46
(i) Except as provided in (c)(ii) and (c)(iii) below, each Part 70 source that is not a major source, a 47
Title IV affected source, or a solid waste incineration unit required to obtain a permit pursuant to section 48
129(e) (42 U.S.C. 7429), is deferred from the obligation to submit an application until 12 months after the 49
Administrator completes a rulemaking to determine how the program should be structured for area sources 50
and the appropriateness of any permanent exemptions in addition to those provided in R307-415-4(2). 51
(ii) General Permits. 52
(A) The director shall develop general permits and application forms for area source categories. 53
(B) After a general permit has been issued for a source category, the director shall establish a due 54
Page 6 of 21

date for permit applications from all area sources in that source category. 1
(C) The director shall provide at least six months notice that the application is due for a source 2
category. 3
(iii) Regulation-specific Requirements. 4
(A) If a regulation promulgated under Section 111 or 112 (42 U.S.C. 7411 or 7412) requires an area 5
source category to submit an application for a Part 70 permit, each area source covered by the requirement 6
must submit an application in accordance with the regulation. 7
(d) Extensions. The owner or operator of any Part 70 source may petition the director for an 8
extension of the application due date for good cause. The due date for major Part 70 sources shall not be 9
extended beyond July 10, 1996. The due date for an area source shall not be extended beyond twelve months 10
after the due date in (c)(i) above. 11
(e) Application shield. If a source submits a timely and complete application under this transition 12
plan, the application shield under R307-415-7b(2) shall apply to the source. If a source submits a timely 13
application and is making sufficient progress toward correcting an application determined to be incomplete, 14
the director may extend the application shield under R307-415-7b(2) to the source when the application is 15
determined complete. The application shield shall not be extended to any major source that has not submitted 16
a complete application by July 10, 1996, or to any area source that has not submitted a complete application 17
within twelve months after the due date in (c)(i) above. 18
(4) Confidential information. Claims of confidentiality on information submitted to EPA may be 19
made pursuant to applicable federal requirements. Claims of confidentiality on information submitted to the 20
Department shall be made and governed according to Section 19-1-306. In the case where a source has 21
submitted information to the Department under a claim of confidentiality that also must be submitted to the 22
EPA, the director shall either submit the information to the EPA under Section 19-1-306, or require the 23
source to submit a copy of such information directly to EPA. 24
(5) Late applications. An application submitted after the deadlines established in R307-415-5a shall 25
be accepted for processing, but shall not be considered a timely application. Submitting an application shall 26
not relieve a source of any enforcement actions resulting from submitting a late application. 27
28
R307-415-5b. Permit Applications: Duty to Supplement or Correct Application. 29
Any applicant who fails to submit any relevant facts or who has submitted incorrect information in a 30
permit application shall, upon becoming aware of such failure or incorrect submittal, promptly submit such 31
supplementary facts or corrected information. In addition, an applicant shall provide additional information 32
as necessary to address any requirements that become applicable to the source after the date it filed a 33
complete application but prior to release of a draft permit. 34
35

Page 10 of 21

70 source, equivalent to that contained in the State Implementation Plan, to be made in the permit issuance, 1
renewal, or significant modification process, and the director elects to use such process, any permit 2
containing such equivalency determination shall contain provisions to ensure that any resulting emissions 3
limit has been demonstrated to be quantifiable, accountable, enforceable, and based on replicable procedures. 4
(2) Permit duration. Except as provided by Section 19-2-109.1(3), the director shall issue permits 5
for a fixed term of five years. 6
(3) Monitoring and related recordkeeping and reporting requirements. 7
(a) Each permit shall contain the following requirements with respect to monitoring: 8

responsible official consistent with R307-415-5d. 43
(ii) Prompt reporting of deviations from permit requirements including those attributable to upset 44
conditions as defined in the permit, the probable cause of such deviations, and any corrective actions or 45
preventive measures taken. The director shall define "prompt" in relation to the degree and type of deviation 46
likely to occur and the applicable requirements. Deviations from permit requirements due to unavoidable 47
breakdowns shall be reported according to the unavoidable breakdown provisions of R307-107. The director 48
may establish more stringent reporting deadlines if required by the applicable requirement. 49
(d) Claims of confidentiality shall be governed by Section 19-1-306. 50

promulgated thereunder. 53
(a) No permit revision shall be required for increases in emissions that are authorized by allowances 54
Page 11 of 21

acquired pursuant to the Acid Rain Program, provided that such increases do not require a permit revision 1
under any other applicable requirement. 2
(b) No limit shall be placed on the number of allowances held by the source. The source may not, 3
however, use allowances as a defense to noncompliance with any other applicable requirement. 4
(c) Any such allowance shall be accounted for according to the procedures established in regulations 5
promulgated under Title IV of the Act. 6
(5) A severability clause to ensure the continued validity of the various permit requirements in the 7
event of a challenge to any portions of the permit. 8
(6) Standard provisions stating the following: 9
(a) The permittee must comply with all conditions of the operating permit. Any permit 10
noncompliance constitutes a violation of the Air Conservation Act and is grounds for any of the following: 11
enforcement action; permit termination; revocation and reissuance; modification; denial of a permit renewal 12
application. 13
(b) Need to halt or reduce activity not a defense. It shall not be a defense for a permittee in an 14
enforcement action that it would have been necessary to halt or reduce the permitted activity in order to 15
maintain compliance with the conditions of this permit. 16
(c) The permit may be modified, revoked, reopened, and reissued, or terminated for cause. The 17
filing of a request by the permittee for a permit modification, revocation and reissuance, or termination, or of 18
a notification of planned changes or anticipated noncompliance does not stay any permit condition, except as 19
provided under R307-415-7f(1) for minor permit modifications. 20
(d) The permit does not convey any property rights of any sort, or any exclusive privilege. 21
(e) The permittee shall furnish to the director, within a reasonable time, any information that the 22
director may request in writing to determine whether cause exists for modifying, revoking and reissuing, or 23
terminating the permit or to determine compliance with the permit. Upon request, the permittee shall also 24
furnish to the director copies of records required to be kept by the permit or, for information claimed to be 25
confidential, the permittee may furnish such records directly to EPA along with a claim of confidentiality. 26
(7) Emission fee. A provision to ensure that a Part 70 source pays fees to the director consistent 27
with R307-415-9. 28
(8) Emissions trading. A provision stating that no permit revision shall be required, under any 29
approved economic incentives, marketable permits, emissions trading and other similar programs or 30
processes for changes that are provided for in the permit. 31
(9) Alternate operating scenarios. Terms and conditions for reasonably anticipated operating 32
scenarios identified by the source in its application as approved by the director. Such terms and conditions: 33
(a) Shall require the source, contemporaneously with making a change from one operating scenario 34
to another, to record in a log at the permitted facility a record of the scenario under which it is operating; 35
(b) Shall extend the permit shield to all terms and conditions under each such operating scenario; 36
and 37
(c) Must ensure that the terms and conditions of each such alternative scenario meet all applicable 38
requirements and the requirements of R307-415. 39
(10) Emissions trading. Terms and conditions, if the permit applicant requests them, for the trading 40
of emissions increases and decreases in the permitted facility, to the extent that the applicable requirements 41
provide for trading such increases and decreases without a case-by-case approval of each emissions trade. 42
Such terms and conditions: 43
(a) Shall include all terms required under R307-415-6a and 6c to determine compliance; 44
(b) Shall extend the permit shield to all terms and conditions that allow such increases and decreases 45
in emissions; and 46
(c) Must meet all applicable requirements and requirements of R307-415. 47
48
R307-415-6b. Permit Content: Federally-Enforceable Requirements. 49
(1) All terms and conditions in an operating permit, including any provisions designed to limit a 50
source's potential to emit, are enforceable by EPA and citizens under the Act. 51
(2) Notwithstanding (1) above, applicable requirements that are not required by the Act or 52
implementing federal regulations shall be included in the permit but shall be specifically designated as being 53
not federally enforceable under the Act and shall be designated as "state requirements." Terms and 54
Page 12 of 21

conditions so designated are not subject to the requirements of R307-415-7a through 7i and R307-415-8 that 1
apply to permit review by EPA and affected states. The director shall determine which conditions are "state 2
requirements" in each operating permit. 3
4
R307-415-6c. Permit Content: Compliance Requirements. 5
All operating permits shall contain all of the following elements with respect to compliance: 6
(1) Consistent with R307-415-6a(3), compliance certification, testing, monitoring, reporting, and 7
recordkeeping requirements sufficient to assure compliance with the terms and conditions of the permit. Any 8
document, including any report, required by an operating permit shall contain a certification by a responsible 9
official that meets the requirements of R307-415-5d; 10
(2) Inspection and entry requirements that require that, upon presentation of credentials and other 11
documents as may be required by law, the permittee shall allow the director or an authorized representative to 12
perform any of the following: 13
(a) Enter upon the permittee's premises where a Part 70 source is located or emissions-related 14
activity is conducted, or where records must be kept under the conditions of the permit; 15
(b) Have access to and copy, at reasonable times, any records that must be kept under the conditions 16
of the permit; 17
(c) Inspect at reasonable times any facilities, equipment (including monitoring and air pollution 18
control equipment), practices, or operations regulated or required under the permit; 19
(d) Sample or monitor at reasonable times substances or parameters for the purpose of assuring 20
compliance with the permit or applicable requirements; 21
(e) Claims of confidentiality on the information obtained during an inspection shall be made 22
pursuant to Section 19-1-306; 23
(3) A schedule of compliance consistent with R307-415-5c(8); 24
(4) Progress reports consistent with an applicable schedule of compliance and R307-415-5c(8) to be 25
submitted semiannually, or at a more frequent period if specified in the applicable requirement or by the 26
director. Such progress reports shall contain all of the following: 27
(a) Dates for achieving the activities, milestones, or compliance required in the schedule of 28
compliance, and dates when such activities, milestones or compliance were achieved; 29
(b) An explanation of why any dates in the schedule of compliance were not or will not be met, and 30
any preventive or corrective measures adopted; 31
(5) Requirements for compliance certification with terms and conditions contained in the permit, 32
including emission limitations, standards, or work practices. Permits shall include all of the following: 33
(a) Annual submission of compliance certification, or more frequently if specified in the applicable 34
requirement or by the director; 35
(b) In accordance with R307-415-6a(3), a means for monitoring the compliance of the source with 36
its emissions limitations, standards, and work practices; 37
(c) A requirement that the compliance certification include all of the following (provided that the 38
identification of applicable information may reference the permit or previous reports, as applicable): 39
(i) The identification of each term or condition of the permit that is the basis of the certification; 40
(ii) The identification of the methods or other means used by the owner or operator for determining 41
the compliance status with each term and condition during the certification period. Such methods and other 42
means shall include, at a minimum, the methods and means required under R307-415-6a(3). If necessary, the 43
owner or operator also shall identify any other material information that must be included in the certification 44
to comply with section 113(c)(2) of the Act, which prohibits knowingly making a false certification or 45
omitting material information; 46
(iii) The status of compliance with the terms and conditions of the permit for the period covered by 47
the certification, including whether compliance during the period was continuous or intermittent. The 48
certification shall be based on the method or means designated in (ii) above. The certification shall identify 49
each deviation and take it into account in the compliance certification. The certification shall also identify as 50
possible exceptions to compliance any periods during which compliance is required and in which an 51
excursion or exceedance as defined under 40 CFR Part 64 occurred; and 52
(iv) Such other facts as the director may require to determine the compliance status of the source; 53
(d) A requirement that all compliance certifications be submitted to the EPA as well as to the 54
Page 13 of 21

director; 1
(e) Such additional requirements as may be specified pursuant to Section 114(a)(3) of the Act, 2
Enhanced Monitoring and Compliance Certification, and Section 504(b) of the Act, Monitoring and Analysis; 3
(6) Such other provisions as the director may require. 4
5
R307-415-6d. Permit Content: General Permits. 6
(1) The director may, after notice and opportunity for public participation provided under R307-415-7
7i, issue a general permit covering numerous similar sources. Any general permit shall comply with all 8
requirements applicable to other operating permits and shall identify criteria by which sources may qualify 9
for the general permit. To sources that qualify, the director shall grant the conditions and terms of the general 10
permit. Notwithstanding the permit shield, the source shall be subject to enforcement action for operation 11
without an operating permit if the source is later determined not to qualify for the conditions and terms of the 12
general permit. General permits shall not be issued for Title IV affected sources under the Acid Rain 13
Program unless otherwise provided in regulations promulgated under Title IV of the Act. 14
(2) Part 70 sources that would qualify for a general permit must apply to the director for coverage 15
under the terms of the general permit or must apply for an operating permit consistent with R307-415-5a 16
through 5e. The director may, in the general permit, provide for applications which deviate from the 17
requirements of R307-415-5a through 5e, provided that such applications meet the requirements of Title V of 18
the Act, and include all information necessary to determine qualification for, and to assure compliance with, 19
the general permit. Without repeating the public participation procedures required under R307-415-7i, the 20
director may grant a source's request for authorization to operate under a general permit, but such a grant to a 21
qualified source shall not be a final permit action until the requirements of R307-415-5a through 5e have 22
been met. 23
24
R307-415-6e. Permit Content: Temporary Sources. 25
The owner or operator of a permitted source may temporarily relocate the source for a period not to 26
exceed that allowed by R307-401-7. A permit modification is required to relocate the source for a period 27
longer than that allowed by R307-401-7. No Title IV affected source may be permitted as a temporary 28
source. Permits for temporary sources shall include all of the following: 29
(1) Conditions that will assure compliance with all applicable requirements at all authorized 30
locations; 31
(2) Requirements that the owner or operator receive approval to relocate under R307-401-7 before 32
operating at the new location; 33
(3) Conditions that assure compliance with all other provisions of R307-415. 34
35
R307-415-6f. Permit Content: Permit Shield. 36
(1) Except as provided in R307-415, the director shall include in each operating permit a permit 37
shield provision stating that compliance with the conditions of the permit shall be deemed compliance with 38
any applicable requirements as of the date of permit issuance, provided that: 39
(a) Such applicable requirements are included and are specifically identified in the permit; or 40
(b) The director, in acting on the permit application or revision, determines in writing that other 41
requirements specifically identified are not applicable to the source, and the permit includes the determination 42
or a concise summary thereof. 43
(2) An operating permit that does not expressly state that a permit shield exists shall be presumed 44
not to provide such a shield. 45
(3) Nothing in this paragraph or in any operating permit shall alter or affect any of the following: 46
(a) The emergency provisions of Section 19-1-202 and Section 19-2-112, and the provisions of 47
Section 303 of the Act, Emergency Orders, including the authority of the Administrator under that Section; 48
(b) The liability of an owner or operator of a source for any violation of applicable requirements 49
under Section 19-2-107(2)(a)(xiii) and Section 19-2-110 prior to or at the time of permit issuance; 50
(c) The applicable requirements of the Acid Rain Program, consistent with Section 408(a) of the 51
Act; 52
(d) The ability of the director to obtain information from a source under Section 19-2-120, and the 53
ability of EPA to obtain information from a source under Section 114 of the Act, Inspection, Monitoring, and 54
Page 14 of 21

Entry. 1

R307-415-7a. Permit Issuance: Action on Application. 3
(1) A permit, permit modification, or renewal may be issued only if all of the following conditions 4
have been met: 5
(a) The director has received a complete application for a permit, permit modification, or permit 6
renewal, except that a complete application need not be received before issuance of a general permit; 7
(b) Except for modifications qualifying for minor permit modification procedures under R307-415-8
7f(1)and (2), the director has complied with the requirements for public participation under R307-415-7i; 9
(c) The director has complied with the requirements for notifying and responding to affected States 10
under R307-415-8(2); 11
(d) The conditions of the permit provide for compliance with all applicable requirements and the 12
requirements of R307-415; 13
(e) EPA has received a copy of the proposed permit and any notices required under R307-415-8(1) 14
and (2), and has not objected to issuance of the permit under R307-415-8(3) within the time period specified 15
therein. 16
(2) Except as provided under the initial transition plan provided for under R307-415-5a(3) or under 17
regulations promulgated under Title IV of the Act for the permitting of Title IV affected sources under the 18
Acid Rain Program, the director shall take final action on each permit application, including a request for 19
permit modification or renewal, within 18 months after receiving a complete application. 20
(3) The director shall promptly provide notice to the applicant of whether the application is 21
complete. Unless the director requests additional information or otherwise notifies the applicant of 22
incompleteness within 60 days of receipt of an application, the application shall be deemed complete. A 23
completeness determination shall not be required for minor permit modifications. 24
(4) The director shall provide a statement that sets forth the legal and factual basis for the draft 25
permit conditions, including references to the applicable statutory or regulatory provisions. The director shall 26
send this statement to EPA and to any other person who requests it. 27
(5) The submittal of a complete application shall not affect the requirement that any source have an 28
approval order under R307-401. 29
30
R307-415-7b. Permit Issuance: Requirement for a Permit. 31
(1) Except as provided in R307-415-7d and R307-415-7f(1)(f)and 7f(2)(e), no Part 70 source may 32
operate after the time that it is required to submit a timely and complete application, except in compliance 33
with a permit issued under these rules. 34
(2) Application shield. If a Part 70 source submits a timely and complete application for permit 35
issuance, including for renewal, the source's failure to have an operating permit is not a violation of R307-415 36
until the director takes final action on the permit application. This protection shall cease to apply if, 37
subsequent to the completeness determination made pursuant to R307-415-7a(3), and as required by R307-38
415-5a(2), the applicant fails to submit by the deadline specified in writing by the director any additional 39
information identified as being needed to process the application. 40
41
R307-415-7c. Permit Renewal and Expiration. 42
(1) Permits being renewed are subject to the same procedural requirements, including those for 43
public participation, affected State and EPA review, that apply to initial permit issuance. 44
(2) Permit expiration terminates the source's right to operate unless a timely and complete renewal 45
application has been submitted consistent with R307-415-7b and R307-415-5a(1)(c). 46
(3) If a timely and complete renewal application is submitted consistent with R307-415-7b and 47
R307-415-5a(1)(c)and the director fails to issue or deny the renewal permit before the end of the term of the 48
previous permit, then all of the terms and conditions of the permit, including the permit shield, shall remain in 49
effect until renewal or denial. 50
51
R307-415-7d. Permit Revision: Changes That Do Not Require a Revision. 52
(1) Operational Flexibility. 53
(a) A Part 70 source may make changes that contravene an express permit term if all of the 54
Page 15 of 21

following conditions have been met: 1
(i) The source has obtained an approval order, or has met the exemption requirements under R307-2
401; 3
(ii) The change would not violate any applicable requirements or contravene any federally 4
enforceable permit terms and conditions for monitoring, including test methods, recordkeeping, reporting, or 5
compliance certification requirements; 6
(iii) The changes are not modifications under any provision of Title I of the Act; and the changes do 7
not exceed the emissions allowable under the permit, whether expressed therein as a rate of emissions or in 8
terms of total emissions. 9
(iv) For each such change, the source shall provide written notice to the director and send a copy of 10
the notice to EPA at least seven days before implementing the proposed change. The seven-day requirement 11
may be waived by the director in the case of an emergency. The written notification shall include a brief 12
description of the change within the permitted facility, the date on which the change will occur, any change in 13
emissions, and any permit term or condition that is no longer applicable as a result of the change. The permit 14
shield shall not apply to these changes. The source, the EPA, and the director shall attach each such notice to 15
their copy of the relevant permit. 16
(b) Emission trading under the State Implementation Plan. Permitted sources may trade increases 17
and decreases in emissions in the permitted facility, where the State Implementation Plan provides for such 18
emissions trades, without requiring a permit revision provided the change is not a modification under any 19
provision of Title I of the Act, the change does not exceed the emissions allowable under the permit, and the 20
source notifies the director and the EPA at least seven days in advance of the trade. This provision is 21
available in those cases where the permit does not already provide for such emissions trading. 22
(i) The written notification required above shall include such information as may be required by the 23
provision in the State Implementation Plan authorizing the emissions trade, including at a minimum, when 24
the proposed change will occur, a description of each such change, any change in emissions, the permit 25
requirements with which the source will comply using the emissions trading provisions of the State 26
Implementation Plan, and the pollutants emitted subject to the emissions trade. The notice shall also refer to 27
the provisions with which the source will comply in the State Implementation Plan and that provide for the 28
emissions trade. 29
(ii) The permit shield shall not extend to any change made under this paragraph. Compliance with 30
the permit requirements that the source will meet using the emissions trade shall be determined according to 31
requirements of the State Implementation Plan authorizing the emissions trade. 32
(c) If a permit applicant requests it, the director shall issue permits that contain terms and conditions, 33
including all terms required under R307-415-6a and 6c to determine compliance, allowing for the trading of 34
emissions increases and decreases in the permitted facility solely for the purpose of complying with a 35
federally-enforceable emissions cap that is established in the permit independent of otherwise applicable 36
requirements. Such changes in emissions shall not be allowed if the change is a modification under any 37
provision of Title I of the Act or the change would exceed the emissions allowable under the permit. The 38
permit applicant shall include in its application proposed replicable procedures and permit terms that ensure 39
the emissions trades are quantifiable and enforceable. The director shall not include in the emissions trading 40
provisions any emissions units for which emissions are not quantifiable or for which there are no replicable 41
procedures to enforce the emissions trades. The permit shall also require compliance with all applicable 42
requirements, and shall require the source to notify the director and the EPA in writing at least seven days 43
before making the emission trade. 44
(i) The written notification shall state when the change will occur and shall describe the changes in 45
emissions that will result and how these increases and decreases in emissions will comply with the terms and 46
conditions of the permit. 47
(ii) The permit shield shall extend to terms and conditions that allow such increases and decreases in 48
emissions. 49
(2) Off-permit changes. A Part 70 source may make changes that are not addressed or prohibited by 50
the permit without a permit revision, unless such changes are subject to any requirements under Title IV of 51
the Act or are modifications under any provision of Title I of the Act. 52
(a) Each such change shall meet all applicable requirements and shall not violate any existing permit 53
term or condition. 54
Page 16 of 21

(b) Sources must provide contemporaneous written notice to the director and EPA of each such 1
change, except for changes that qualify as insignificant under R307-415-5e. Such written notice shall 2
describe each such change, including the date, any change in emissions, pollutants emitted, and any 3
applicable requirements that would apply as a result of the change. 4
(c) The change shall not qualify for the permit shield. 5
(d) The permittee shall keep a record describing changes made at the source that result in emissions 6
of a regulated air pollutant subject to an applicable requirement, but not otherwise regulated under the permit, 7
and the emissions resulting from those changes. 8
(e) The off-permit provisions do not affect the requirement for a source to obtain an approval order 9
under R307-401. 10
11
R307-415-7e. Permit Revision: Administrative Amendments. 12
(1) An "administrative permit amendment" is a permit revision that: 13
(a) Corrects typographical errors; 14
(b) Identifies a change in the name, address, or phone number of any person identified in the permit, 15
or provides a similar minor administrative change at the source; 16
(c) Requires more frequent monitoring or reporting by the permittee; 17
(d) Allows for a change in ownership or operational control of a source where the director 18
determines that no other change in the permit is necessary, provided that a written agreement containing a 19
specific date for transfer of permit responsibility, coverage, and liability between the current and new 20
permittee has been submitted to the director; 21
(e) Incorporates into the operating permit the requirements from an approval order issued under 22
R307-401, provided that the procedures for issuing the approval order were substantially equivalent to the 23
permit issuance or modification procedures of R307-415-7a through 7i and R307-415-8, and compliance 24
requirements are substantially equivalent to those contained in R307-415-6a through 6g; 25
(2) Administrative permit amendments for purposes of the acid rain portion of the permit shall be 26
governed by regulations promulgated under Title IV of the Act. 27
(3) Administrative permit amendment procedures. An administrative permit amendment may be 28
made by the director consistent with the following: 29
(a) The director shall take no more than 60 days from receipt of a request for an administrative 30
permit amendment to take final action on such request, and may incorporate such changes without providing 31
notice to the public or affected States provided that the director designates any such permit revisions as 32
having been made pursuant to this paragraph. The director shall take final action on a request for a change in 33
ownership or operational control of a source under (1)(d) above within 30 days of receipt of a request. 34
(b) The director shall submit a copy of the revised permit to EPA. 35
(c) The source may implement the changes addressed in the request for an administrative 36
amendment immediately upon submittal of the request. 37
(4) The director shall, upon taking final action granting a request for an administrative permit 38
amendment, allow coverage by the permit shield for administrative permit amendments made pursuant to 39
(1)(e) above which meet the relevant requirements of R307-415-6a through 6g, 7 and 8 for significant permit 40
modifications. 41
42
R307-415-7f. Permit Revision: Modification. 43
The permit modification procedures described in R307-415-7f shall not affect the requirement that a 44
source obtain an approval order under R307-401 before constructing or modifying a source of air pollution. 45
A modification not subject to the requirements of R307-401 shall not require an approval order in addition to 46
the permit modification as described in this section. A permit modification is any revision to an operating 47
permit that cannot be accomplished under the program's provisions for administrative permit amendments 48
under R307-415-7e. Any permit modification for purposes of the acid rain portion of the permit shall be 49
governed by regulations promulgated under Title IV of the Act. 50
(1) Minor permit modification procedures. 51
(a) Criteria. Minor permit modification procedures may be used only for those permit modifications 52
that: 53
(i) Do not violate any applicable requirement or require an approval order under R307-401; 54
Page 17 of 21

(ii) Do not involve significant changes to existing monitoring, reporting, or recordkeeping 1
requirements in the permit; 2
(iii) Do not require or change a case-by-case determination of an emission limitation or other 3
standard, or a source-specific determination for temporary sources of ambient impacts, or a visibility or 4
increment analysis; 5
(iv) Do not seek to establish or change a permit term or condition for which there is no 6
corresponding underlying applicable requirement and that the source has assumed to avoid an applicable 7
requirement to which the source would otherwise be subject. Such term or condition would include a 8
federally enforceable emissions cap assumed to avoid classification as a modification under any provision of 9
Title I or an alternative emissions limit approved pursuant to regulations promulgated under Section 112(i)(5) 10
of the Act, Early Reduction; and 11
(v) Are not modifications under any provision of Title I of the Act. 12
(b) Notwithstanding (1)(a)above and (2)(a) below, minor permit modification procedures may be 13
used for permit modifications involving the use of economic incentives, marketable permits, emissions 14
trading, and other similar approaches, to the extent that such minor permit modification procedures are 15
explicitly provided for in the State Implementation Plan or an applicable requirement. 16
(c) Application. An application requesting the use of minor permit modification procedures shall 17
meet the requirements of R307-415-5c and shall include all of the following: 18
(i) A description of the change, the emissions resulting from the change, and any new applicable 19
requirements that will apply if the change occurs; 20
(ii) The source's suggested draft permit; 21
(iii) Certification by a responsible official, consistent with R307-415-5d, that the proposed 22
modification meets the criteria for use of minor permit modification procedures and a request that such 23
procedures be used; 24
(iv) Completed forms for the director to use to notify EPA and affected States as required under 25
R307-415-8. 26
(d) EPA and affected State notification. Within five working days of receipt of a complete permit 27
modification application, the director shall notify EPA and affected States of the requested permit 28
modification. The director promptly shall send any notice required under R307-415-8(2)(b) to EPA. 29
(e) Timetable for issuance. The director may not issue a final permit modification until after EPA's 30
45-day review period or until EPA has notified the director that EPA will not object to issuance of the permit 31
modification, whichever is first. Within 90 days of the director's receipt of an application under minor permit 32
modification procedures or 15 days after the end of EPA's 45-day review period under R307-415-8(3), 33
whichever is later, the director shall: 34
(i) Issue the permit modification as proposed; 35
(ii) Deny the permit modification application; 36
(iii) Determine that the requested modification does not meet the minor permit modification criteria 37
and should be reviewed under the significant modification procedures; or 38
(iv) Revise the draft permit modification and transmit to EPA the new proposed permit modification 39
as required by R307-415-8(1). 40
(f) Source's ability to make change. A Part 70 source may make the change proposed in its minor 41
permit modification application immediately after it files such application if the source has received an 42
approval order under R307-401 or has met the approval order exemption requirements under R307-413-1 43
through 6. After the source makes the change allowed by the preceding sentence, and until the director takes 44
any of the actions specified in (1)(e)(i) through (iii) above, the source must comply with both the applicable 45
requirements governing the change and the proposed permit terms and conditions. During this time period, 46
the source need not comply with the existing permit terms and conditions it seeks to modify. However, if the 47
source fails to comply with its proposed permit terms and conditions during this time period, the existing 48
permit terms and conditions it seeks to modify may be enforced against it. 49
(g) Permit shield. The permit shield under R307-415-6f shall not extend to minor permit 50
modifications. 51
(2) Group processing of minor permit modifications. Consistent with this paragraph, the director 52
may modify the procedure outlined in (1) above to process groups of a source's applications for certain 53
modifications eligible for minor permit modification processing. 54

(a) Criteria. Group processing of modifications may be used only for those permit modifications: 1
(i) That meet the criteria for minor permit modification procedures under (1)(a) above; and 2
(ii) That collectively are below the following threshold level: 10 percent of the emissions allowed 3
by the permit for the emissions unit for which the change is requested, 20 percent of the applicable definition 4
of major source in R307-415-3, or five tons per year, whichever is least. 5
(b) Application. An application requesting the use of group processing procedures shall meet the 6
requirements of R307-415-5c and shall include the following: 7
(i) A description of the change, the emissions resulting from the change, and any new applicable 8
requirements that will apply if the change occurs. 9
(ii) The source's suggested draft permit. 10
(iii) Certification by a responsible official, consistent with R307-415-5d, that the proposed 11
modification meets the criteria for use of group processing procedures and a request that such procedures be 12
used. 13
(iv) A list of the source's other pending applications awaiting group processing, and a determination 14
of whether the requested modification, aggregated with these other applications, equals or exceeds the 15
threshold set under R307-415-7e(2)(a)(ii). 16
(v) Certification, consistent with R307-415-5d, that the source has notified EPA of the proposed 17
modification. Such notification need only contain a brief description of the requested modification. 18
(vi) Completed forms for the director to use to notify EPA and affected States as required under 19
R307-415-8. 20
(c) EPA and affected State notification. On a quarterly basis or within five business days of receipt 21
of an application demonstrating that the aggregate of a source's pending applications equals or exceeds the 22
threshold level set under (2)(a)(ii) above, whichever is earlier, the director shall notify EPA and affected 23
States of the requested permit modifications. The director shall send any notice required under R307-415-24
8(2)(b)to EPA. 25
(d) Timetable for issuance. The provisions of (1)(e) above shall apply to modifications eligible for 26
group processing, except that the director shall take one of the actions specified in (1)(e)(i) through (iv) above 27
within 180 days of receipt of the application or 15 days after the end of EPA's 45-day review period under 28
R307-415-8(3), whichever is later. 29
(e) Source's ability to make change. The provisions of (1)(f) above shall apply to modifications 30
eligible for group processing. 31
(f) Permit shield. The provisions of (1)(g) above shall also apply to modifications eligible for group 32
processing. 33
(3) Significant modification procedures. 34
(a) Criteria. Significant modification procedures shall be used for applications requesting permit 35
modifications that do not qualify as minor permit modifications or as administrative amendments. Every 36
significant change in existing monitoring permit terms or conditions and every relaxation of reporting or 37
recordkeeping permit terms or conditions shall be considered significant. Nothing herein shall be construed 38
to preclude the permittee from making changes consistent with R307-415 that would render existing permit 39
compliance terms and conditions irrelevant. 40
(b) Significant permit modifications shall meet all requirements of R307-415, including those for 41
applications, public participation, review by affected States, and review by EPA, as they apply to permit 42
issuance and permit renewal. The director shall complete review on the majority of significant permit 43
modifications within nine months after receipt of a complete application. 44
45
R307-415-7g. Permit Revision: Reopening for Cause. 46
(1) Each issued permit shall include provisions specifying the conditions under which the permit 47
will be reopened prior to the expiration of the permit. A permit shall be reopened and revised under any of 48
the following circumstances: 49
(a) New applicable requirements become applicable to a major Part 70 source with a remaining 50
permit term of three or more years. Such a reopening shall be completed not later than 18 months after 51
promulgation of the applicable requirement. No such reopening is required if the effective date of the 52
requirement is later than the date on which the permit is due to expire, unless the terms and conditions of the 53
permit have been extended pursuant to R307-415-7c(3). 54
Page 19 of 21

(b) Additional requirements, including excess emissions requirements, become applicable to an Title 1
IV affected source under the Acid Rain Program. Upon approval by EPA, excess emissions offset plans shall 2
be deemed to be incorporated into the permit. 3
(c) The director or EPA determines that the permit contains a material mistake or that inaccurate 4
statements were made in establishing the emissions standards or other terms or conditions of the permit. 5
(d) EPA or the director determines that the permit must be revised or revoked to assure compliance 6
with the applicable requirements. 7
(e) Additional applicable requirements are to become effective before the renewal date of the permit 8
and are in conflict with existing permit conditions. 9
(2) Proceedings to reopen and issue a permit shall follow the same procedures as apply to initial 10
permit issuance and shall affect only those parts of the permit for which cause to reopen exists. Such 11
reopening shall be made as expeditiously as practicable. 12
(3) Reopenings under (1) above shall not be initiated before a notice of such intent is provided to the 13
Part 70 source by the director at least 30 days in advance of the date that the permit is to be reopened, except 14
that the director may provide a shorter time period in the case of an emergency. 15
16
R307-415-7h. Permit Revision: Reopenings for Cause by EPA. 17
The director shall, within 90 days after receipt of notification that EPA finds that cause exists to 18
terminate, modify or revoke and reissue a permit, forward to EPA a proposed determination of termination, 19
modification, or revocation and reissuance, as appropriate. The director may request a 90-day extension if a 20
new or revised permit application is necessary or if the director determines that the permittee must submit 21
additional information. 22
23
R307-415-7i. Public Participation. 24
The director shall provide for public notice, comment and an opportunity for a hearing on initial 25
permit issuance, significant modifications, reopenings for cause, and renewals, including the following 26
procedures: 27
(1) The director shall give notice by publishing a legal notice on the public legal notice website 28
under Subsection 42-1-101(2) and by posting the notice and the draft permit on the Division's website for the 29
duration of the public comment period. The director shall give notice to persons on a mailing list developed 30
by the director, including those who request in writing to be on the list, and by other means if necessary to 31
assure adequate notice to the affected public. 32
(2) The notice shall identify: 33
(a) the Part 70 source; 34
(b) the name and address of the permittee; 35
(c) the name and address of the director; 36
(d) the activity or activities involved in the permit action; 37
(e) the emissions change involved in any permit modification; 38
(f) the name, address, and telephone number of a person from whom interested persons may obtain 39
additional information, including copies of the permit draft, the application, all relevant supporting materials, 40
including any compliance plan or compliance and monitoring certification, and all other materials available to 41
the director that are relevant to the permit decision; 42
(g) a brief description of the comment procedures; and 43
(h) the time and place of any hearing that may be held, including a statement of procedures to 44
request a hearing, unless a hearing has already been scheduled. 45
(3) The director shall provide such notice and opportunity for participation by affected States as is 46
provided for by Section R307-415-8. 47
(4) The director shall provide at least 30 days for public comment and shall give notice of any public 48
hearing at least 30 days in advance of the hearing. 49
(5) The director shall keep a record of the commenters and also of the issues raised during the public 50
participation process, and such records shall be available to the public and to EPA. 51
52
R307-415-8. Permit Review by EPA and Affected States. 53
(1) Transmission of information to EPA. 54
Page 20 of 21

(a) The director shall provide to EPA a copy of each permit application, including any application 1
for permit modification, each proposed permit, and each final operating permit, unless the Administrator has 2
waived this requirement for a category of sources, including any class, type, or size within such category. 3
The applicant may be required by the director to provide a copy of the permit application, including the 4
compliance plan, directly to EPA. Upon agreement with EPA, the director may submit to EPA a permit 5
application summary form and any relevant portion of the permit application and compliance plan, in place of 6
the complete permit application and compliance plan. To the extent practicable, the preceding information 7
shall be provided in computer-readable format compatible with EPA's national database management system. 8
(b) The director shall keep for five years such records and submit to EPA such information as EPA 9
may reasonably require to ascertain whether the Operating Permit Program complies with the requirements of 10
the Act or of 40 CFR Part 70. 11
(2) Review by affected States. 12
(a) The director shall give notice of each draft permit to any affected State on or before the time that 13
the director provides this notice to the public under R307-415-7i, except to the extent R307-415-7f(1) or (2) 14
requires the timing to be different, unless the Administrator has waived this requirement for a category of 15
sources, including any class, type, or size within such category. 16
(b) The director, as part of the submittal of the proposed permit to EPA, or as soon as possible after 17
the submittal for minor permit modification procedures allowed under R307-415-7f(1) or (2), shall notify 18
EPA and any affected State in writing of any refusal by the director to accept all recommendations for the 19
proposed permit that the affected State submitted during the public or affected State review period. The 20
notice shall include the director's reasons for not accepting any such recommendation. The director is not 21
required to accept recommendations that are not based on applicable requirements or the requirements of 22
R307-415. 23
(3) EPA objection. If EPA objects to the issuance of a permit in writing within 45 days of receipt of 24
the proposed permit and all necessary supporting information, then the director shall not issue the permit. If 25
the director fails, within 90 days after the date of an objection by EPA, to revise and submit a proposed 26
permit in response to the objection, EPA may issue or deny the permit in accordance with the requirements of 27
the Federal program promulgated under Title V of the Act. 28
(4) Public petitions to EPA. If EPA does not object in writing under R307-415-8(3), any person 29
may petition EPA under the provisions of 40 CFR 70.8(d) within 60 days after the expiration of EPA's 45-30
day review period to make such objection. If EPA objects to the permit as a result of a petition, the director 31
shall not issue the permit until EPA's objection has been resolved, except that a petition for review does not 32
stay the effectiveness of a permit or its requirements if the permit was issued after the end of the 45-day 33
review period and prior to an EPA objection. If the director has issued a permit prior to receipt of an EPA 34
objection under this paragraph, EPA may modify, terminate, or revoke such permit, consistent with the 35
procedures in 40 CFR 70.7(g) except in unusual circumstances, and the director may thereafter issue only a 36
revised permit that satisfies EPA's objection. In any case, the source will not be in violation of the 37
requirement to have submitted a timely and complete application. 38
(5) Prohibition on default issuance. The director shall not issue an operating permit, including a 39
permit renewal or modification, until affected States and EPA have had an opportunity to review the 40
proposed permit as required under this Section. 41
42
R307-415-9. Fees for Operating Permits. 43
(1) Definitions. The following definition applies only to Subsection R307-415-9: "Allowable 44
emissions" are emissions based on the potential to emit stated by the director in an approval order, the State 45
Implementation Plan or an operating permit. 46
(2) Applicability. As authorized by Section 19-1-201, all Part 70 sources must pay annual fees to 47
support the operating permit program. 48
(3) Calculation of Annual Emission Fee for a Part 70 Source. 49
(a) The emission fee shall be calculated for all chargeable pollutants emitted from a Part 70 source, 50
even if only one unit or one chargeable pollutant triggers the applicability of Rule R307-415 to the source. 51
(i) Fugitive emissions and fugitive dust shall be counted when determining the emission fee for a 52
Part 70 source. 53
(ii) An emission fee shall not be charged for emissions of any amount of a chargeable pollutant if the 54
Page 21 of 21

emissions are already accounted for within the emissions of another chargeable pollutant. 1
(iii) An emission fee shall not be charged for emissions of any one chargeable pollutant from any 2
one Part 70 source in excess of 4,000 tons per year. 3
(iv) Emissions resulting directly from an internal combustion engine for transportation purposes or 4
from a non-road vehicle shall not be counted when calculating chargeable emissions for a Part 70 source. 5
(b) The emission fee portion of the total fee for an existing source prior to the issuance of an 6
operating permit, shall be based on the most recent emission inventory available unless a Part 70 source 7
elected, prior to July 1, 1992, to base the fee for one or more pollutants on allowable emissions established in 8
an approval order or the State Implementation Plan. 9
(c) The emission fee portion of the total fee after the issuance or renewal of an operating permit shall 10
be based on the most recent emission inventory available unless a Part 70 source elects, prior to the issuance 11
or renewal of the permit, to base the fee for one or more chargeable pollutants on allowable emissions for the 12
entire term of the permit. 13
(d) When a new Part 70 source begins operating, it shall pay the emission fee portion of the total fee 14
for that fiscal year, prorated from the date the source begins operating plus any additional Part 70 fees. The 15
emission fee portion of the total fee for a new Part 70 source shall be based on allowable emissions until that 16
source has been in operation for a full calendar year, and has submitted an inventory of actual emissions. If a 17
new Part 70 source is not billed in the first billing cycle of its operation, the emission fee plus any additional 18
fees shall be calculated using the emissions that would have been used had the source been billed at that time. 19
This fee shall be in addition to any subsequent emission fees. 20
(e) When a Part 70 source is no longer subject to Part 70, the emission fee portion of the total fee 21
shall be prorated to the date that the source ceased to be subject to Part 70. If the Part 70 source has already 22
paid an emission fee that is greater than the prorated fee, the balance of the emission fee will be refunded. No 23
other Part 70 fees shall be refunded. 24
(i) If that Part 70 source again becomes subject to the emission fee requirements, it shall pay an 25
emission fee for that fiscal year prorated from the date the source again became subject to the emission fee 26
requirements plus any additional fees typically charged for Part 70 sources for that year. The fee shall be 27
based on the emission inventory during the last full year of operation. The emission fee shall continue to be 28
based on actual emissions reported for the last full calendar year of operation until that source has been in 29
operation for a full calendar year and has submitted an updated inventory of actual emissions. 30
(ii) If a Part 70 source has chosen to base the emission fee on allowable emissions, then the prorated 31
fee shall be calculated using allowable emissions. 32
(f) Modifications. The method for calculating the emission fee for a source shall not be affected by 33
modifications at that source, unless the source demonstrates to the director that another method for 34
calculating chargeable emissions is more representative of operations after the modification has been made. 35
(g) The director may presume that potential emissions of any chargeable pollutant for the source are 36
equivalent to the actual emissions for the source if recent inventory data are not available. 37
(4) Collection of Fees. 38
(a) The Part 70 fees are due on October 1 of each calendar year or 45 days after the source has 39
received notice of the amount of the fee, whichever is later. 40
(b) The director may require any owner or operator of the source who fails to pay the annual fees by 41
the due date to pay interest on the fee and a penalty under Subsection 19-2-109.1(4)(a) or revoke the 42
operating permit under Subsection 19-2-109.1(4)(b). 43
(c) An owner or operator may contest a Part 70 fee assessment, or associated penalty, under 19-2-44
109.1(5). 45
(d) To reinstate the permit revoked under Subsection 19-2-109.1(4)(b), an owner or operator shall 46
pay the outstanding fees, a penalty of not more than 50% of outstanding fees, and interests on the outstanding 47
fees computed at 12% annually. 48
