Regional Transportation and Climate Initiative (TCI)
Connecticut, Delaware, District of Columbia (D.C.), Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, and Virginia signed a Declaration of Intent to create the TCI, a regional initiative to improve transportation, develop a clean energy economy, and reduce carbon emissions and air pollutants from the transportation sector. The signatory states and D.C. agree to explore and develop policies and programs that result in greater energy efficiency of regional transportation systems and reduce emissions. Additionally, states support the deployment of clean vehicles and fueling infrastructure, such as electric vehicle supply equipment, to maximize the economic opportunities and emissions reductions. For more information, see the TCI website.
Medium- and Heavy-Duty Zero Emission Vehicle (ZEV) Deployment Support
California, Colorado, Connecticut, District of Columbia, Hawaii, Maine, Maryland, Massachusetts, New Jersey, New York, North Carolina, Oregon, Pennsylvania, Rhode Island, Vermont, and Washington (signatory states) signed a memorandum of understanding (MOU) to support the deployment of medium- and heavy-duty ZEVs through involvement in a Multi-State ZEV Task Force (Task Force).
By January 2021, the Task Force will develop a multi-state action plan to support electrification of medium- and heavy-duty vehicles. The Task Force will consider actions to accomplish the goals of the MOU, including limiting all new medium- and heavy-duty vehicles sales in the signatory states to ZEVs by 2050. The signatory states will also seek to accelerate the deployment of medium- and heavy-duty ZEVs to benefit disadvantaged communities and explore opportunities to coordinate and partner with key stakeholders.
For more information, see the Multi-State Medium- and Heavy-Duty Zero Emission Vehicle MOU.
Zero Emission Vehicle (ZEV) Deployment Support
Maryland joined California, Connecticut, Maine, Massachusetts, New Jersey, New York, Oregon, Rhode Island, and Vermont in signing a memorandum of understanding (MOU) to support the deployment of ZEVs through involvement in a ZEV Program Implementation Task Force (Task Force). In May 2014, the Task Force published a ZEV Action Plan (Plan) identifying 11 priority actions to accomplish the goals of the MOU, including deploying at least 3.3 million ZEVs and adequate fueling infrastructure within the signatory states by 2025. The Plan also includes a research agenda to inform future actions. On an annual basis, each state must report on the number of registered ZEVs, the number of public electric vehicle supply equipment (EVSE) and hydrogen fueling stations, and available information regarding workplace fueling for ZEVs.
In June 2018, the Task Force published a new ZEV Action Plan for 2018-2021. Building on the 2014 Action Plan, the 2018 Action Plan makes recommendations for states and other key partners in five priority areas:
- Raising consumer awareness and interest in electric vehicle technology;
- Building out a reliable and convenient residential, workplace and public charging/fueling infrastructure network;
- Continuing and improving access to consumer purchase and non-financial incentives;
- Expanding public and private sector fleet adoption; and
- Supporting dealership efforts to increase ZEV sales.
For more information, see the Multi-State ZEV Task Force website.
Alternative Fuel Use Requirement
At least 50% of state vehicles using petroleum diesel fuel must use a minimum blend of 5% biodiesel (B5) or other biofuel approved by the U.S. Environmental Protection Agency as a fuel or fuel additive. This requirement does not apply to any state vehicles for which the use of biodiesel or other biofuel will void the manufacturer's warranty for that vehicle. Biodiesel fuel is defined as a fuel composed of mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats that is designated B100 or a blend of biodiesel that meets the requirements of ASTM specification D6751. Additionally, bi-fuel and flexible fuel vehicles capable of operating on either alternative fuel or conventional fuel must use alternative fuel when it is available. (Reference Maryland Statutes, State Finance and Procurement Code 14-408, and Policies and Procedures for Vehicle Fleet Management)
Alternative Fuel Vehicle (AFV) Access to Tunnels
An AFV powered by propane or natural gas may only use the Baltimore Harbor Tunnel and the Fort McHenry Tunnel if the vehicle has a dedicated alternate fuel system installed by the manufacturer of the vehicle or a fuel system that has been properly converted to an alternate fuel system, conforms to applicable federal regulations and industry standards, has a fuel capacity that does not exceed 150 pounds, and displays all proper markings and symbols. (Reference Code of Maryland Regulations 11.07.01.03)
Idle Reduction Requirement
A motor vehicle engine may not operate for more than five consecutive minutes when the vehicle is not in motion, with the following exceptions: 1) when traffic conditions or mechanical difficulties do not allow the vehicle to operate; 2) when it is necessary to operate heating, cooling or auxiliary equipment installed on the vehicle; 3) to bring vehicle to manufacturer's recommended operating temperature; or 4) if idling is necessary to accomplish the intended use of the vehicle. (Reference Maryland Statutes, Transportation Code 22-402)
Zero Emission Vehicle (ZEV) Sales Requirements and Low Emission Vehicle (LEV) Standards
Maryland has adopted the California motor vehicle emissions standards and compliance requirements specified in Title 13 of the California Code of Regulations. Manufacturers must meet the greenhouse gas emissions standard and the ZEV production and sales requirements. The Maryland Department of Environment may adopt regulations to exempt certain vehicles from the program, including motor vehicles sold for registration outside of Maryland and motor vehicles that would be exempt from the LEV program established under California law. For more information, see the Maryland Clean Cars Program website. (Reference Maryland Statutes, Environment Code 2-1101 through 2-1106)
Aftermarket Alternative Fuel Vehicle (AFV) Conversion Requirements
Conventional original equipment manufacturer vehicles altered to operate on propane, natural gas, methane, ethanol, or electricity are classified as aftermarket AFV conversions. All vehicle conversions for vehicles certified only to California Air Resources Board (CARB) standards must meet current applicable CARB standards for aftermarket conversions. However, U.S. Environmental Protection Agency (EPA) certified conversion kits may be used on EPA 50-state certified vehicles and vehicles with dual-certification that are 14,000 pounds or less. (Reference Code of Maryland Regulations 26.11.34)
Low-Speed Vehicle Access to Roadways
A low-speed vehicle is defined as a four-wheeled electric vehicle that has a maximum speed capability of 20 miles per hour (mph) to 25 mph. A low-speed vehicle must be registered with the Maryland Motor Vehicle Administration and comply with federal safety standards contained in Title 49 of the Code of Federal Regulations, section 571.500. The State Highway Administration or any local authority may prohibit the use of low-speed vehicles on any controlled access highway in its jurisdiction. Low-speed vehicles are only permitted on highways with a speed limit of up to 30 mph, but may, except in certain situations, cross highways for which the maximum speed limit exceeds 45 mph if the intersection is controlled by a traffic light or a four-way stop sign. (Reference Maryland Statutes, Transportation Code 11-130.1, 21-313, 21-1125, and 22-101)
Limited Speed Vehicle Access to Roadways
A limited speed vehicle is defined as a vehicle that is capable of achieving a maximum speed of at least 25 miles per hour (mph) but no more than 55 mph. Limited speed vehicles may only operate on highways on which the maximum speed of the vehicle exceeds the posted speed limit by at least 5 mph. Limited speed vehicles may not be sold without the required limited speed emblems. Additionally, limited speed vehicle purchasers must be informed in writing, of the limitations of vehicle use on highways. (Reference Maryland Statutes, Transportation Code 15-313, 21-804, and 21-805.1)
