Whatever you call it, the development of this unprecedented rule probably will go on the rest of the summer. The first public discussion about this rule took place more than two years ago.

This time around, both Fresno meetings will be on June 10 -- one from noon to 4 p.m. and one from 5 p.m. to 8 p.m. They are planned in the Fresno County Plaza Ballroom, 2220 Fresno St.

Truckers are saying the rule will put many small operators out of business. On the other hand, diesel trucks are the No. 1 source of nitrogen oxides, or NOx, one of two key ozone gases.

The issue boils down to health, money and timing. Slow down the cleanup, and more truckers will stay in business, industry officials say. Speed it up, and fewer people will be exposed to lung disease, heart problems and early death, environmentalists say.

It is a balancing act that the California Air Resource must perfect with the help of the public. Mark your calendars.
