42 U.S. Code § 7590 - General provisions
If any State adopts enforceable provisions in an implementation plan applicable to a nonattainment area which provides that existing State refueling facilities will be made available to the public for the purchase of clean alternative fuels or that State-operated refueling facilities for such fuels will be constructed and operated by the State and made available to the public at reasonable times, taking into consideration safety, costs, and other relevant factors, in approving such plan under section 7410 of this title and part D, the Administrator may credit a State with the emission reductions for purposes of part D  attributable to such actions.
The Administrator shall have no authority under this part to mandate the production of clean-fuel vehicles except as provided in the California pilot test program or to specify as applicable the models, lines, or types of, or marketing or price practices, policies, or strategies for, vehicles subject to this part. Nothing in this part shall be construed to give the Administrator authority to mandate marketing or pricing practices, policies, or strategies for fuels.
 So in original. Probably should refer to part D of subchapter I.
In subsec. (c), “chapter 301 of title 49” substituted for “the National Motor Vehicle Traffic Safety Act of 1966 [15 U.S.C. 1381 et seq.]”, meaning “the National Traffic and Motor Vehicle Safety Act of 1966 [15 U.S.C. 1381 et seq.]”, on authority of Pub. L. 103–272, § 6(b), July 5, 1994, 108 Stat. 1378, the first section of which enacted subtitles II, III, and V to X of Title 49, Transportation.
