Willamette Valley Field Burning

The Oregon Department of Agriculture regulates the burning of certain grass seed fields in limited areas of the Willamette Valley each summer.
 
The Oregon Department of Agriculture regulates the burning of up to 15,000 acres of certain grass seed fields in limited areas of the Willamette Valley each summer. Another 2,000 acres of field burning can be authorized by DEQ as emergency burning, but only as a remedy to address major disease outbreaks or insect infestations. Other restrictions apply to general field burning if it’s conducted near any school, hospital, airport, or under a power transmission line. Except for emergency field burning, all general field burning is regulated by ODA.
 
Under state law, ODA operates the smoke management program for Willamette Valley field burning, while DEQ's role is limited to oversight of this program.
