H.R. 10589 — Consumer Fuel Costs Relief Act

This section sets federal excise tax rates on taxable motor and aviation fuels to zero from the date of enactment through September 30, 2027, and suspends the Leaking Underground Storage Tank Trust Fund financing rate during that period. It requires the Treasury to transfer equivalent amounts from the general fund to the Highway Trust Fund and the Leaking Underground Storage Tank Trust Fund. It directs the Treasury, Federal Trade Commission, and Commodity Futures Trading Commission to ensure producers and sellers pass the full tax reduction on to consumers.
