Kem C. Gardner Policy Institute Utah Roadmap

Addressing Policy Making to Improve Air Quality and Impacts of a Changing Climate

At the request of the Utah Legislature, the Kem C. Gardner Policy Institute – with the assistance of a 37-person Technical Advisory Committee – prepared this Utah Roadmap to assist with legislative policy making to improve air quality and address causes and impacts of a changing climate. The Utah Roadmap identifies areas of opportunity to further reduce air emissions and ensure a healthy, productive and prosperous future for all Utahns. On January 6, the Gardner Institute released the Utah Roadmap for public review and will consider feedback as the recommendations are finalized.

The Gardner Institute and Technical Advisory Committee reviewed past Utah-specific work on air quality and changing climate completed by Envision Utah and the 2007 Blue Ribbon Advisory Council. This previous analysis included over 200 policy options. After a six-month expert assessment, we prioritized 55 of these options as those with the greatest impact at the least cost. The Gardner Institute then selected seven strategies – or what we call mileposts – as the first areas of focus.

Utah Foundations Driving Towards a Cleaner Future

Alternative Fuel Vehicles in Utah

Driving Toward a Cleaner Future: Alternative Fuel Vehicles in Utah examines the incentives and disincentives around electric cars, as well as the policy decisions around preparation for a wide proliferation of electric vehicles in the future. It also examines the incentives and requirements around public and private heavy-duty fleet vehicles.


Key Findings of this Report

  • Electric vehicles – or battery electric cars and plug-in hybrids – accounted for less than 2% of the nation’s new vehicle market share in 2018. In Utah, electric’s market share was about 1.6%.
  • Addressing the fears of consumers is a core challenge in alternative fuel vehicle adoption. Less than a quarter of Americans consider purchasing electric cars because of concerns about running out of power, the availability of charging stations and initial vehicle cost.
  • Utah’s relatively small electric vehicle tax credit was not renewed in 2016, yet electric vehicle market share has continued to increase.
  • The top electric-vehicle-adopting states – all in the West – offer significant incentives. However, the 10 states with the highest market share growth in 2018 offer no incentives (though they all had 2017 market share under one percent).
  • There is evidence that the looming threat of expiring tax credits can encourage short-term market uptake of alternative fuel vehicles.
  • Due to state and local investment, as well as the Volkswagen Settlement and private actors, Utah’s electric vehicle charging infrastructure is poised to quickly expand
  • Large fleet vehicles account for one-third to one-half of Utah’s vehicle emissions, even though they account for only 3% of the vehicle miles traveled.
  • Alternative-fuel, heavy-duty fleet vehicles are more expensive than diesel and have large infrastructure costs, but offer large fuel and maintenance savings.
  • To encourage the market’s embrace of alternative fuel vehicles, state and local governments should continue to explore opportunities to encourage private actors to deploy alternative fuel infrastructure for customers, tenants, employees and visitors.
  • Cities and counties have at least two potential roles to play: adopting building codes that are “future-proof” for the growth in alternative fuel vehicles, and retiring older public-service diesel fuel fleets.
  • Utah may get a substantial air quality return on its tax credit investments by continuing to focus incentives on heavy-duty fleet vehicles and renewing them in 2020.
  • To encourage the market’s embrace of alternative fuel vehicles, public and private sector stakeholders should mount public information campaigns to explain the growing availability of alternative fuel infrastructure and address other consumer fears.

2020 DERA School Bus Rebates Program

The Diesel Emissions Reduction Act

The Diesel Emissions Reduction Act (DERA) of 2010 allows the EPA to offer rebates in addition to grants to reduce harmful emissions from older, dirtier diesel vehicles. The rebate program has funded vehicle replacements or retrofits for over 2,000 vehicles. Typically, the rebate application period opens in the fall and projects are completed in less than one year.

2020 DERA School Bus Rebates Closed

School buses travel over four billion miles each year, providing the safest transportation to and from school for more than 25 million American children every day. However, diesel exhaust from these buses has a negative impact on human health, especially for children, who have a faster breathing rate than adults and whose lungs are not yet fully developed.

The 2020 DERA School Bus Rebates will offer over $10 million to public and private fleet owners for the replacement of old diesel school buses with new buses certified to EPA’s cleanest emission standards. Selected applicants that scrap and replace their old diesel buses will receive a rebate of $20,000-$65,000 per bus depending on the fuel type of the replacement bus.

Vehicle Emissions Program

Salt Lake County Health Department


Vehicle Repair Assistance Program (VRAP)

Depending on the age and overall condition of a vehicle failing the emissions test, low-income vehicle owners may qualify for vehicle repair assistance. We require a completed application and supporting documentation.


Before you may register a motor vehicle (either gasoline or diesel-powered) for operation in Salt Lake County, it must pass an emissions test.

  • Vehicles less than six years old are tested every other year.
  • Vehicles more than six years old must be tested every year.
  • Farm-plated vehicles and vehicles of model year 1967 or older are exempt from testing.

Independent testing facilities located throughout Salt Lake County perform the emissions testing. The  Vehicle Emissions Program licenses and regulates the facilities.

A malfunctioning vehicle can emit one hundred times the amount of pollution that it would if it were working properly.

Every day, the program keeps tons of pollutants out of the Salt Lake Valley’s air:

  • 82 tons of carbon monoxide (CO)
  • 4 tons of hydrocarbons (HC)
  • 4 tons of nitrogen oxide (NOx)


Motor vehicles are responsible for more than 70% of the air pollution that affects our health. When a vehicle is operating properly, its emissions levels are very low. However, a malfunctioning vehicle can emit one hundred times the amount of pollution that it would if it were working properly. Properly tuned and well-maintained vehicles also provide better performance and fuel economy for the owner.

If your vehicle fails the emissions test:

  • Use a repair facility and technician who is familiar with your vehicle and its emissions system.
  • Secure a written estimate that includes diagnosis and recommended repairs.
  • If you are not satisfied with the estimate or diagnosis, get a second technician’s opinion or contact the Air Quality Bureau.
  • Check your vehicle owner’s manual for information specific to your vehicle. Many emissions systems are covered by warranties, if still applicable.

You cannot register a failing vehicle in Salt Lake County until it is properly repaired, retested, and passes the test.


In very rare cases, vehicle owners have made repairs toward the major cause of the high emissions and those repairs have failed to reduce the pollution levels to below the standard. In some of those cases, SLCoHD may issue a repair waiver to allow a failing vehicle to be registered for that year.

A vehicle may qualify for a waiver if it has:

  • failed at least two emissions inspections.
  • received emissions-related repairs from a recognized repair facility.
  • fulfills all other waiver requirements.

Waivers are handled on a case-by-case basis and may or may not be granted. A waiver is a last resort. The vehicle must be inspected by a SLCoHD vehicle emissions technician to review all test data and repair information, and to verify the ineffective repairs. Contact the Air Quality Bureau for more information about waivers.


USE ONLY THE FREE ADOBE ACROBAT READER TO COMPLETE AND SUBMIT YOUR APPLICATION OR RECERTIFICATION FORM. Some web browser PDF viewers may not properly submit your application or form.


Note that permits are not transferable; when a change of ownership occurs at a permitted facility, the new owner must apply for a new permit and pay all applicable fees.

Emissions Stations in good standing with SLCoHD may apply to become a Vehicle Repair Assistance Program (VRAP) repair station. For more information, contact the Air Quality Bureau.

Utah’s Road Usage Charge Program

Utah Department of Transportation

Utah roads are maintained using taxes from gasoline sales. As vehicles become more fuel efficient and the number of electric vehicles grows, the Utah Department of Transportation and Division of Motor Vehicles is changing to a per-mile fee as a way for drivers to pay their portion of roadway operations and maintenance.

Utah’s Road Usage Charge Program is voluntary for electric and hybrid vehicle owners. UDOT and DMV have contracted with emovis to operate the program. The choice is yours.

During the 2018 Legislative session, lawmakers instituted an alternative fuel vehicle fee to cover a portion of those vehicles’ contribution to building and maintaining Utah’s transportation system. ​This fee is in addition to the annual vehicle registration fee assessed on all vehicles in the State​. Utah’s Road Usage Charge provides a choice for owners of alternative fuel vehicles to pay by the mile in lieu of paying the alternative fuel vehicle fee.

Frequently Asked Questions on Electric Vehicle Batteries



Electric vehicles contain lithium-ion
batteries (LIBs) that are both large
and expensive, and these LIBs likely
have significant storage capacity
remaining when they no longer meet
the power and energy demands
of a typical vehicle application.
That remaining LIB capacity could
provide a financial opportunity to
many individuals and institutions
along the possible value chain: This
could include vehicle owners (value
recovery), battery repurposers (who
collect, evaluate, and repackage used
LIBs), battery second-life users (grid
operators, businesses, hospitals, etc.),
and, ultimately, battery recyclers
(who recover valuable battery
materials via physical, thermal,
and chemical methods).


Second life refers to a new,
nonautomotive use of an automotive
LIB after its initial use in a vehicle.
Refurbished or remanufactured
batteries are those LIBs that have
come out of service, were evaluated
and repaired if needed, and were
graded as meeting application
specifications and made available
to the original LIB application.

iREV Report

Alternative Fuel Vehicles and Emergency Plans: A Planning Policy Report for Utah

This report was produced through a partnership between the National Association of State Energy Officials (NASEO), the Utah Governor’s Office of Energy Development (OED), and the Utah Clean Cities Coalition (UCCC), and examines how alternative fuel vehicles (AFVs)1 can bolster resilience by diversifying Utah’s vehicle fleet, and be leveraged as an emergency response resource in the event of a disruption to the state’s transportation fuels sector.


In Utah, emergency preparedness efforts are ongoing at the state-level, and include planning, training, exercises, and funding for infrastructure and equipment. Utah’s Emergency Operation Plan (EOP) covers broad challenges facing the energy sector. In order to address the complex issues relating to energy sector emergencies, the state also created the Utah Energy Emergency Plan (EEP). This report includes recommended language that could be included in future updates to the EEP to ensure that alternative fuel vehicles are effectively deployed during a petroleum disruption to improve the response and recovery effort. Future OED publications, supported by the U.S. State Energy Program, could also include OED’s role in creating a resilient emergency response fleet within the state, capable of operating on alternative fuels in the event of a disruption to the petroleum sector.

Utah Clean Cities 2018 Annual Report

The U.S. Department of Energy’s (DOE) Clean Cities program advances the nation’s economic, environmental, and energy security by supporting local actions to reduce petroleum use in transportation. A national network of nearly 100 Clean Cities coalitions brings together stakeholders in the public and private sectors to deploy alternative and renewable fuels, idle-reduction measures, fuel economy improvements, and new transportation technologies, as they emerge.  


Every year, each Clean Cities coalition submits to DOE an annual report of its activities and accomplishments for the previous calendar year. Coalition coordinators, who lead the local coalitions, provide information and data via an online database managed by the National Renewable Energy Laboratory (NREL). The data characterize membership, funding, projects, and activities of the coalitions. The coordinators also submit data on the sales of alternative fuels, deployment of alternative fuel vehicles and hybrid electric vehicles, idle-reduction initiatives, fuel economy activities, and programs to reduce vehicle miles traveled. NREL and DOE analyze the data and translate them into petroleum-use and greenhouse gas reduction impacts for individual coalitions and the program as a whole. This report summarizes those impacts for Utah Clean Cities. To view aggregated data for all local coalitions that participate in the Clean Cities program, visit cleancities.energy.gov/accomplishments.
