- Encourage EV manufacturers to stock and market a wide variety of EVs within the Signatory States;
- Identify, respond to, and collaborate on funding opportunities to support the development of the plan; and
- Support the build-out of direct current (DC) fast charging stations along EV corridors through investments, partnerships, and other mechanisms.
Natural Gas and Hydrogen Tax
Compressed natural gas (CNG) and hydrogen are taxed at a rate of $0.171 per gasoline gallon equivalent (GGE). Liquefied natural gas (LNG) is taxed at a rate of $0.171 per diesel gallon equivalent (DGE). One GGE is equal to 5.660 pounds (lbs.) of CNG or 2.198 lbs. of hydrogen. One DGE is equal to 6.06 lbs. of LNG. The tax rate for natural gas and hydrogen will be annually adjusted by the State Tax Commission (Commission) not to exceed $0.225 per GGE or DGE. The Commission will publish the adjusted fuel tax no later than 60 days prior to the effective date. For more information, see the Utah State Tax Commission Fuel Taxes website. (Reference Utah Code 59-13-102 and 59-13-301)
Compressed Natural Gas (CNG) Vehicle Aftermarket Conversion Requirements
Vehicles converted to operate on CNG must be inspected and certified in accordance with relevant safety standards by a CSA America-certified CNG Fuel System Inspector. The vehicle must also be tested to ensure that it meets emissions standards in the applicable county, or the county with the most lenient emissions standards if the vehicle is registered in a county without its own emissions standards. A person who performs a conversion must certify to the vehicle owner that the conversion does not tamper with, circumvent, or otherwise affect the vehicle's on-board diagnostic system, if applicable. A CSA America-certified CNG Fuel System Inspector must also inspect the vehicle every three years, or every 36,000 miles, and after a collision occurring at a speed greater than five miles per hour.
The Utah Division of Air Quality may develop programs to facilitate coordination between government agencies and the private sector regarding emissions and anti-tampering compliance testing, vehicle safety, and potential improvements in the air quality of the state.
(Reference Utah Code 19-1-406)
Natural Gas Rate and Cost Recovery Authorization
The Utah Public Service Commission (Commission) may allow a gas corporation to set a natural gas vehicle fuel rate that is less than full cost of service if it is reasonable and in the interest of the public. If the Commission approves such a request, the remaining costs may be spread to other customers of the gas corporation.
The Commission may also allow a gas corporation to recover expenditures directly related to the construction, operation, and maintenance of natural gas fueling stations and related facilities through an incremental surcharge to all of its rate classes. The Commission may allow this only if it finds that the expenditures are reasonable, do not exceed $5 million in any calendar year, are in the interest of the public, and will result in an annual incremental increase in revenue greater than 50% of the corporation's annual revenue requirement for the stations and facilities.
The Commission may also allow a gas corporation to establish a natural gas incentive or program to support the use of natural gas, including renewable natural gas, if it is reasonable and in the interest of the public. If the Commission approves such a request, the remaining costs may be spread to other customers of the gas corporation.
