Top area polluters tracked

What's the biggest polluter category?
By far, it's cars, trucks, trains and aerosol cans -- not factories, power plants and other stationary sources.
Collectively, the little emitters, such as residential fireplaces, vehicles, farms and household products, create vast pools of pollution. Power plants and factories are known for their nitrogen oxides emissions, yet they produce less than half the nitrogen oxides that come from cars, trucks, trains, mobile farm equipment and other moving sources in the valley.
Emissions are way down from 1999 among stationary sources. Why?
Because the rules are getting tighter and tighter, said Brenda Turner, spokeswoman for the San Joaquin Valley Air Pollution Control District, which regulates stationary sources of pollution. "So many of our large facilities (are) close to the amount of reductions that are even possible," she said.
Big stationary facilities have been through several generations of pollution-cutting technology in an attempt to meet new rules, said Roger Christy, a spokesman and air-quality expert for Chevron USA. The rules continue to touch every kind of oil-field engine, he said.
Cutting pollution "is getting tougher to do,"
