Natural gas fueling stations are exempt from the requirement to file Air Pollutant Emission Notices, as they have a negligible impact on air quality. (Reference Colorado Air Quality Control Commission Regulations Number 3, Part A, Section II.D.1.hhh)

Laws and Regulations

Regional Electric Vehicle (REV) West Plan

Colorado joined Arizona, Idaho, Montana, Nevada, New Mexico, Utah, and Wyoming (Signatory States) in signing the REV West memorandum of understanding (MOU) to create an Intermountain West Electric Vehicle (EV) Corridor that will make it possible to seamlessly drive an EV across the Signatory States' major transportation corridors. Signatory States are committed to:

  • Create best practices and procedures that will enhance EV adoption by: promoting EV consumer acceptance and awareness by addressing range anxiety, coordinating on EV charging station locations, and leveraging economies of scale;
  • Create minimum standards for EV charging stations, including standards for administration, interoperability, operations, and management;
  • Identify and develop opportunities to incorporate EV charging stations into planning and development processes such as building codes, metering policies, and renewable energy generation projects;
  • Encourage EV manufacturers to stock and market a wide variety of EVs within the Signatory States; and
  • Identify, respond to, and collaborate on funding opportunities to support the development of the Plan.
The Signatory States have formed a Coordination Group composed of senior leadership from each state which will meet on a quarterly basis and report on the above actions. A final report will be completed by April 1, 2018.

Support for Autonomous Vehicle Testing and Operation

Colorado state agencies must support the testing and operation of autonomous vehicles. Autonomous vehicle usage is authorized if the driving system complies with state and federal laws, or if approved by the Colorado State Patrol and the Colorado Department of Transportation. Autonomous vehicles are motor vehicles equipped with technology that allows vehicle automation to perform one or more driving functions without the direct control of the driver. (Reference Senate Bill 17-213, 2017)

State Agency Petroleum Reduction and Reporting Requirements

Colorado state agencies and departments must reduce petroleum-based fuel consumption on a per vehicle basis and across the fleet. For non-exempt vehicles, the minimum annual reduction is 4% per vehicle, and at least 20% by Fiscal Year (FY) 2020 compared to a FY 2015 baseline. The exempt vehicle requirement is a minimum annual reduction of 2% per vehicle, and at least 10% by FY 2020. State agencies and departments must also achieve a total reduction in petroleum-based fuel consumption by 15% (or 7.5% for exempt vehicles) by FY 2020. The Colorado Department of Personnel and Administration may consider certain vehicles to be exempt based on agency requests; agencies must request vehicle exemptions prior to establishing the FY 2015 baseline.

State agencies must use EnergyCAP to track progress towards these goals. All state executive agencies and departments will provide the Colorado Greening Government Coordinating Council (Council) with any information not captured in EnergyCAP that is needed to complete calculations and reporting.

(Reference Executive Order D 2015-013, 2015)

Inter-Agency Fleet Improvement Coordination

The Colorado Energy Office, Department of Transportation (CDOT), Department of Public Health and Environment, and Department of Personnel and Administration (DPA) will establish a State Fleet Sub-Council (Sub-Council) to help develop, implement, and improve programs, plans, and policies that save money, reduce emissions, promote domestic fuel use, and conserve natural resources. The Sub-Council will:

  • Develop standard procedures and formulas for modeling and monitoring potential alternative fuel vehicles (AFVs) and fuel reduction efforts that link acquisition and operations budgets;
  • Create an idle reduction policy for state agencies;
  • Create a process that allows fleet coordinators to replace vehicles with AFVs before standard retirement age if the replacement is cost-effective;
  • Identify and evaluate other fuel-saving practices and develop procedures for their implementation; and
  • Evaluate alternative financing options for state fleet vehicles including leasing, energy performance contracting, and other options that may reduce costs.

In addition, DPA and CDOT will establish policies and procedures to promote the cost-effective use of non-petroleum fuel vehicles and other fleet efficiency improvements. The policies must strive for the use of non-petroleum based fuels at least 90% of the time when cost-effective.

(Reference Executive Order D 2015-013, 2015)

Fleet Purchase and Pricing Agreement Requirements

The Colorado state fleet and the Colorado Department of Transportation (CDOT) must purchase natural gas vehicles (NGVs) where natural gas fueling is available or planned, whenever possible. Where NGVs are not viable options, other alternative fuel vehicles (AFVs) such as plug-in electric, hybrid electric, and propane vehicles, must be considered. All new vehicles purchased must be either alternatively fueled or exceed federal Corporate Average Fuel Economy standards.

In addition, CDOT and the Colorado Department of Personnel and Administration (DPA) must include AFVs in state pricing agreements; AFVs include compressed natural gas, hybrid electric, plug-in electric, and propane vehicles. CDOT and DPA must also determine opportunities to expand state pricing into alternative fuel and fuel-efficient heavy-duty equipment, as well as into idle reduction technologies and telematics.

(Reference Executive Order D 2015-013, 2015)

Workplace Charging Evaluation

Colorado state agencies and departments must evaluate opportunities to improve commuting options for employees, including the installation of workplace charging for plug-in electric vehicles. Agencies and departments may coordinate with the Colorado Energy Office as needed for technical support. (Reference Executive Order D 2015-013, 2015)

Electric Vehicle Supply Equipment (EVSE) Multi-Unit Dwelling Installations and Access

A tenant may install Level 1 or Level 2 EVSE at their own expense on or in leased premises. The landlord may seek a fee or reimbursement for the actual cost of electricity as well as the cost of installation or upgrades to existing equipment. In addition, the tenant may request that the EVSE be accessible by other tenants, in which case the EVSE must be in compliance with all applicable requirements, and the landlord may seek a fee to reserve a specific parking space. The landlord may also require the tenant to comply with safety, system registration, and aesthetic requirements or provisions.

Common interest communities must also provide residents with an opportunity to charge plug-in electric vehicles and may not create restrictions around EVSE. Common interest communities are encouraged to allow EVSE and to apply for grants from the Electric Vehicle Grant Fund or otherwise fund the installation of EVSE on common property as an amenity for residents and guests.

(Reference Colorado Revised Statutes 38-12-601 and 38-33.3-106.8)

Alternative Fuel Tax

PEV owners must pay an annual fee of $50, in addition to other registration fees, for a PEV decal. The decal will authorize PEV owners to use public electric vehicle supply equipment (EVSE) in Colorado. Fees contribute to the Highway Users Tax Fund and the Electric Vehicle Grant Fund, which provides grants for EVSE. (Reference Colorado Revised Statutes 42-3-306)

Alternative Fuel Resale and Generation Regulations

A corporation or individual that resells alternative fuel supplied by a public utility for use in an alternative fuel vehicle (AFV) is not subject to regulation as a public utility. Additionally, a corporation or individual that owns, controls, operates, or manages a facility that generates electricity exclusively for use in AFV charging or fueling facilities is not subject to regulation as a public utility provided that the electricity is generated on the property where the charging or fueling facilities are located and the electricity is generated from a renewable resource. For the purposes of this definition, alternative fuel is defined as propane, liquefied natural gas, compressed natural gas, or electricity. (Reference Colorado Revised Statutes 40-1-103.3)

Vehicle Fleet Maintenance and Fuel Cost-Savings Contracts

Government fleets may finance the lease or purchase cost of alternative fuel vehicles and alternative fueling infrastructure through energy performance contracts where vehicle operational and fuel cost savings pay for the capital investment. Energy performance contracts must show that the annual cost savings associated with the fueling and maintenance of vehicles with higher efficiency ratings or alternative fueling methods is equal to or higher than the annual contract payments. (Reference Colorado Revised Statutes 24-30-2001 through 24-30-2003 and 29-12.5-101 through 29-12.5-104)

Alternative Fuel Vehicle (AFV) Registration

Upon registering a motor vehicle with the Colorado Department of Revenue Division of Motor Vehicles, the vehicle owner must report the type of alternative fuel used to operate the vehicle and whether the vehicle is dedicated to one alternative fuel or uses more than one fuel. The Department of Revenue provides forms for the purpose of registering motor vehicles and must include space for the following fuel types: gasoline, diesel, propane, electricity, natural gas, methanol/M85, ethanol/E85, biodiesel, and other. For more information, see the Colorado Department of Revenue Division of Motor Vehicles page. (Reference Colorado Revised Statutes 42-3-113)

Low-Speed Electric Vehicle (EV) Access to Roadways

A low-speed EV is a self-propelled vehicle using electricity as its primary propulsion method, has at least three wheels in contact with the ground, does not use handlebars to steer, displays a vehicle identification number, and meets manufacturer requirements as defined in Title 49 of the Code of Federal Regulations section 565. A low-speed EV may be operated on a roadway with a speed limit of up to 40 miles per hour (mph) as long as the roadway's lane is at least 11 feet wide, the roadway provides two or more lanes in either direction, and the Colorado Department of Transportation has determined that operation of a low-speed EV on the roadway poses no substantial safety risk. Otherwise, a low-speed EV may only be operated on a roadway with a speed limit of 35 mph or less. Regardless, a low-speed EV may directly cross any roadway with a speed limit greater than 35 mph. Low-speed EVs may not be sold or offered for sale unless they comply with state vehicle safety requirements.

A Class-B low-speed EV is defined as a low-speed EV that is capable of traveling at greater than 25 mph but less than 45 mph. A Class-B low-speed EV may be operated only on a roadway with a speed limit of 45 mph or less, but may directly cross a roadway with a speed limit greater than 45 mph. The Colorado Department of Revenue may not register or issue a title for a Class-B low-speed EV until after the U.S. Department of Transportation has adopted a federal motor vehicle safety standard for low-speed EVs that authorizes operation at greater than 25 mph but less than 45 mph. Neither a low-speed EV nor a Class-B low-speed EV may be operated on a limited-access highway.

Renewable and Alternative Fuel Storage Tank Regulations

The Colorado Department of Labor and Employment, Division of Oil and Public Safety, enforces rules concerning the placement of underground and aboveground storage tanks that contain alternative and renewable fuel. For the purpose of these regulations, an alternative fuel is a motor fuel that combines petroleum-based fuel products with renewable fuels; a renewable fuel is a motor vehicle fuel produced from plant or animal products or wastes. (Reference 7 Code of Colorado Regulations 1101-14 and Colorado Revised Statutes 8-20.5-202 and 8-20.5-302)

State Agency Alternative Fuel Use and Vehicle Acquisition Requirement

The Colorado Department of Personnel and Administration (DPA) requires all state-owned diesel vehicles and equipment to be fueled with a fuel blend of 20% biodiesel (B20), subject to the availability of the fuel and so long as the price differential is not greater than $0.10 more per gallon as compared to conventional diesel. Biodiesel is defined as fuel composed of mono-alkyl esters of long chain fatty acids derived from plant or animal matter that meets ASTM specifications and is produced in Colorado.

Additionally, DPA has adopted a policy to increase the use of alternative fuels and establish objectives to increase its use for each succeeding year. DPA must purchase motor vehicles that operate on compressed natural gas (CNG), plug-in hybrid electric vehicles, or vehicles that operate on other alternative fuels, subject to the availability of vehicles and adequate fueling infrastructure and assuming the incremental base or life cycle cost of the vehicle is not more than 10% over the cost of a comparable dedicated conventional vehicle. DPA has adopted a policy to allow some vehicles to be exempt from this requirement if available alternative fuel vehicles (AFVs) do not meet application requirements.

On or before November 1 of each year, DPA must submit a report to the general assembly outlining vehicle purchases, including alternative fuel and conventional vehicles; alternative fueling infrastructure availability in the state; AFV purchase exemptions; administrative policies in place to facilitate the purchase of AFVs; suggested changes to facilitate the gradual conversion of the motor vehicle fleet to AFVs; and a plan for the necessary infrastructure development.

(Reference Executive Order D 2015-013, 2015, and Colorado Revised Statutes 24-30-1104)

Alternative Fuel Definition

Alternative fuel is defined as compressed natural gas, propane, ethanol, or any mixture containing 85% or more ethanol (E85) with gasoline or other fuels, electricity, or any other fuels, which may include clean diesel and reformulated gasoline, so long as the Colorado Air Quality Control Commission determines that these other fuels result in comparable reductions in carbon monoxide emissions and brown cloud pollutants. Alternative fuel does not include any fuel product that contains or is treated with methyl tertiary butyl ether (MTBE). (Reference Colorado Revised Statutes 25-7-106.8)

Gasoline and Diesel Gallon Equivalent Definition

Motor fuels, including alternative fuels, may be sold by gasoline gallon equivalent (GGE) or diesel gallon equivalent (DGE) as long as the dispenser used for the sale of motor fuel in GGEs or DGEs clearly displays the applicable conversion factor and other required information. (Reference Colorado Revised Statutes 8-20-232.5)
