Vehicles account for half of Utah's emissions. We can't clean our air without reducing them. Simple as that.

So, hurray for the Environmental Protection Agency's Tier 3 proposals to cut by an incredible 80 percent the nitrogen oxides and volatile organic compounds — the "big contributors to Utah's summer ozone problem and winter smog" — and cut by 70 percent "the fine soot that plagues our valleys during inversions."

And all for a penny a gallon for new lower-sulfur gas and $134 added to the cost of new car. Seems like a no-bainer.

Yet Karma Thompson, of Salt Lake's Tesoro refinery (and a member of the Utah Air Quality Board), and Lee Peacock, president of the Utah Petroleum Association, counsel "caution." That's like listening to a representative of R.J. Reynolds Tobacco Co. urge caution about banning cigarette smoking on airplanes.

Caution? Breathing our air on red-alert days is similar to smoking 5-10 cigarettes a day! Follow the health experts, not the manufacturers of bad air.

Gov. Gary Herbert, show backbone. Speak for the people, who elected you, not the polluters, who paid for your campaign.
