42 U.S.C. § 13259 — Secretary’s recommendations to Congress

(a) Recommendations to require availability or acquisition: If the Secretary^* decides, under section 13257(f) of this title, that a fleet requirement program isn't necessary, the Secretary must tell Congress. After that notice, the Secretary has 2 years to prepare and send Congress, by rule, recommendations for requirements or incentives covering: (1) fuel suppliers, so they make replacement fuels available to the public, including building the necessary delivery systems; (2) suppliers of alternative-fuel vehicles, so they make those vehicles available to the public and make sure related services exist; and (3) motor vehicle drivers, so they use replacement fuels — as much as needed to reach the replacement-fuel goals and to keep fuel availability and vehicle availability in step with each other.

(b) Fair and equitable application: In doing this, the Secretary must recommend spreading these requirements proportionately and fairly across all the relevant fuel suppliers and buyers, and vehicle suppliers and buyers.
