The $5 billion transportation plan Ohio Gov. Bob Taft proposed Tuesday is far-reaching, ambitious and sorely needed. It also depends on pennies - pennies that the state now sends to Washington, never to see again.

The unfair nature of the gasoline tax that penalizes Ohio for selling pollution-reducing ethanol fuel at the pump. Right now 2.5 cents of every 13.2 cents in tax on each gallon of ethanol sold is siphoned off to the federal government. Putting that money into Ohio's Highway Trust Fund would generate about $60 million a year for the state.

We have beaten this drum before, and we intend to keep it up until the message gets through. Ohio uses about 45 percent ethanol in corn-based gasohol, which is taxed at a lower rate than pure gasoline. That means less tax money from every fill up comes back to this state than in states where dirtier formulations of gas are prevalent.

It is illogical to penalize the state for using cleaner, renewable resources to fuel its cars.

Fortunately, it is beginning to look like Washington is hearing Ohio's complaint. A Senate energy bill passed last week would double ethanol use and return the 2.5 cents to the state. U.S. Rep. Rob Portman, R-Terrace Park, has introduced a similar bill in the House.

Portman stood at Taft's side Tuesday, emphasizing the need for the legislation if Ohio's transportation needs are to be met.

The governor's 10-year plan would deal with several major highway and bridge problems affecting Greater Cincinnati. In particular, it would help pay for the replacement of the Brent Spence Bridge across the Ohio River. Interstates 75 and 71 come together and cross the river on that outdated and overcrowded span. It is one of the most crucial highway links in the entire country.

"Transportation is the lifeblood of Ohio," Taft said. "The majority of these funds are in place, yet the entire program is dependent on us receiving more of our gas tax back."

Congress should act on Portman's bill quickly. Ohio needs every penny it can get.
