Outdoor burning rules in Benton County, WA — also called the burn ban, open burning, or fire restriction ordinance — set when you can burn yard waste, debris, or run a recreational fire.
The Benton Clean Air Agency regulates outdoor burning countywide. Residents inside Urban Growth Areas cannot burn for disposal at all; those outside may burn only on approved burn days. Forecast wind over 20 mph shuts residential burning down.
Outdoor burning in Benton County is controlled by the Benton Clean Air Agency (BCAA), not just the county. Residents inside an Urban Growth Area, including around Kennewick, Richland, West Richland, and Prosser, may not burn yard or land-clearing debris for disposal. Outside the UGA, burning of dry natural vegetation is allowed only on days BCAA declares a burn day, in piles no larger than 4 by 4 by 3 feet. Burning garbage, plastics, treated wood, and construction debris is always illegal. Agricultural burning needs a written BCAA permit; orchard prunings, tumbleweeds, and ditch-line vegetation are exempt. DNR permits govern forest and rangeland burning.
Illegal open burning: Benton Clean Air Agency penalties up to $1,000 per day, and Washington Clean Air Act violations can reach $10,000 per day. DNR wildfire cost recovery applies to escaped fires.
