Concerned about Air-quality in Oregon, what about field burning?

Wednesday, a 100 acres field burn near Corvallis failed to raise on the winds, creating a gray cloud that alarmed residents and Monroe, Junction City, Elmira, Veneta and as far south as Lorane.
"It didn't get the lift," said John Byers, coordinator of the state smoke management program. "It did not look good, so we did not continue."

33 rural dwellers called the lane regional air pollution authority to complain about the smoke. 26 called the state's field burning complaint line.

This is the third field burning this summer that it prompts a rash of complaints from Lane County residents. On August 27, smoke intruded on Springfield, prompting 275 calls. On August 24, a burn south of Fern Ridge Lake bothered about a dozen callers.

The smoke rises annually when about 200 Willamette Valley grass seed farmers burn the straw off their fields after harvest.

Living in the Willamette Valley, we go through this every year. The smoke just gets trapped.

The farmers claim that they have to do field burning to kill off bugs and disease however, there are alternative proven methods in accomplishing this but they are more expensive.

However, why isn't Kulongoski who is so concerned about changing the automotive environmental standards to California environmental standards concerned about field burning?
