Laws and Regulations
Alternative Fuel Use and Vehicle Acquisition Requirements
State agency fleets with more than 15 vehicles, excluding emergency and law enforcement vehicles, may not purchase or lease a motor vehicle unless the vehicle uses natural gas, propane, ethanol or fuel blends of at least 85% ethanol (E85), methanol or fuel blends of at least 85% methanol (M85), biodiesel or fuel blends of at least 20% biodiesel (B20), or electricity (including plug-in hybrid electric vehicles). Waivers may be granted for fleets if the fleet will operate primarily in areas where neither the state agency or a supplier can reasonably be expected to establish adequate fueling infrastructure for these fuels or the agency is unable to obtain equipment or fueling facilities necessary to operate alternative fuel vehicles at a cost that is no greater than the net costs of using conventional fuels.
Covered state agency fleets must consist of at least 50% of vehicles that are able to operate on alternative fuels and use these fuels at least 80% of the time the vehicles are driven. Covered state agencies may meet these requirements through the purchase of new vehicles or the conversion of existing vehicles. State agencies that purchase passenger vehicles or other ground transportation vehicles for general use must ensure that at least 25% of the vehicles purchased during any state fiscal biennium, other than exempted vehicles, meet or exceed federal Tier II, Bin 3 emissions standards.
(Reference Texas Statutes, Government Code 2158.004-2158.009)
Alternative Fuel Vehicle (AFV) Registration Tracking Program
The Texas Department of Motor Vehicles (Department) collects data on the number of AFVs registered in the state. The Department must submit an annual report to the Texas Legislature detailing the results of each data collection year. For the purpose of this program, AFVs include electric, natural gas, propane, hydrogen fuel cell, ethanol, methanol, and hybrid vehicles.
(Reference Texas Statutes, Transportation Code 502.001 and 502.004)
Authorization of Governmental Alternative Fuel Fleet Grant Program
The Texas Commission on Environmental Quality (TCEQ) must administer a grant program for governmental alternative fuel fleets to provide grants for the purchase or lease of a new vehicle and the purchase, lease, or installation of alternative fueling equipment. Eligible alternative fuels include natural gas, propane, hydrogen, and electricity. State agencies and political subdivisions are eligible to apply for a grant under the program if the entity operates a fleet of more than 15 vehicles. Mass transit and school transportation providers will also be eligible for grants.
TCEQ must establish standardized vehicle grant amounts based on the incremental costs associated with the purchase or lease of different categories of motor vehicle, including the fuel type, vehicle class, and other categories TCEQ considers appropriate. TCEQ will also establish standardized fueling equipment grant amounts.
