42 U.S.C. § 17051 — Renewable fuel dispenser requirements

(a) Market penetration reports. The Secretary, working with the Secretary of Transportation, must figure out and report to Congress each year how many flexible-fuel vehicles are being used, broken down by regions the Secretary sets. (b) Dispenser feasibility study. By December 19, 2009, the Secretary — working with the Department of Transportation — must report to Congress on whether to require motor fuel retailers to install E-85-compatible pumps and related systems in regions where flexible-fuel vehicles make up 15 percent of vehicles. The study must look at: (1) how commercially available E-85 fuel is, and how many competing E-85 wholesale suppliers exist in a region; (2) how much yearly financial help federal, state, and nonprofit sources give for installing E-85-compatible infrastructure; (3) how many retail locations can't fit more than 2 underground storage tank dispensers; and (4) what it costs retailers to install and sell E-85-compatible pumps and systems, and any effect that might have on the price of motor vehicle fuel.
