Fuel Choice and Deregulation Act of 2021
This bill revises requirements governing the use of alternative fuels in vehicles.
Among other things, the bill revises requirements on aftermarket vehicle conversions that enable older vehicles to use alternative fuels. Under current law, the Environmental Protection Agency (EPA) must certify such conversions. This bill removes such certification requirements.
The bill also bans the EPA from prohibiting or controlling biomass fuel.
In addition, the bill revises the Corporate Average Fuel Economy standards for certain vehicles that are able to operate on something other than petroleum-based fuel, such as electric vehicles.
Finally, the bill revises the Reid Vapor Pressure (RVP) requirements to provide for the year-round sale of ethanol-gasoline fuel blends that contain more than 10% denatured anhydrous ethanol. RVP is a metric of gasoline volatility (i.e., how quickly fuel evaporates into the atmosphere). Current law prohibits the sale of gasoline that exceed certain RVP limits during the high ozone season (i.e., the summer months). However, current law provides waivers from this requirement, including a waiver that gives certain ethanol-gasoline fuel blends containing 10% denatured anhydrous ethanol a higher RVP limit under certain conditions. This bill expands the waiver to include ethanol-gasoline fuel blends containing more than 10% of such ethanol, thus allowing year-round sales of such fuel blends.
To provide regulatory relief to alternative fuel producers and 
                   consumers, and for other purposes.

    Be it enacted by the Senate and House of Representatives of the 
United States of America in Congress assembled,

SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Fuel Choice and Deregulation Act of 
2021''.

SEC. 2. ALTERNATIVE FUELS.

    (a) Aftermarket Conversions of Motor Vehicles to Alternative 
Fuel.--Section 203 of the Clean Air Act (42 U.S.C. 7522) is amended by 
adding at the end the following:
    ``(c) Older Vehicles.--
            ``(1) In general.--The aftermarket conversion of a motor 
        vehicle to alternative fuel operation shall not--
                    ``(A) be considered tampering under this section if 
                the aftermarket conversion system manufacturer or the 
                person performing the conversion demonstrates that the 
                development and engineering sophistication of the 
                conversion technology is--
                            ``(i) matched to an appropriate motor 
                        vehicle or group of motor vehicles; and
                            ``(ii) well-designed and installed in 
                        accordance with good engineering judgment so 
                        that the aftermarket conversion system does not 
                        degrade emission performance, as compared to 
                        the performance of the motor vehicle or motor 
                        vehicles before the conversion; or
                    ``(B) require the Administrator to issue a 
                certificate of conformity.
            ``(2) Label.--The person performing a conversion described 
        in paragraph (1) shall affix a label to the motor vehicle 
        stating that--
                    ``(A) the motor vehicle has been equipped with an 
                aftermarket conversion system; and
                    ``(B) the installation of that system occurred 
                after the initial sale of the motor vehicle.
            ``(3) No preclusion of orders.--Nothing in this subsection 
        precludes the Administrator from issuing an order to prohibit 
        the manufacture, sale, distribution, or installation of an 
        aftermarket conversion system if the Administrator has evidence 
        that the installation of the aftermarket conversion system on a 
        motor vehicle degrades emission performance.''.
    (b) Biomass Fuels.--Section 211 of the Clean Air Act (42 U.S.C. 
7545) is amended by adding at the end the following:
    ``(w) Biomass Fuels.--Notwithstanding any other provision of this 
Act, the Administrator may not prohibit or control biomass fuel (as 
defined in section 203 of the Biomass Energy and Alcohol Fuels Act of 
1980 (42 U.S.C. 8802)) under this Act.''.
