Kennewick does not have a year-round curbside yard-waste cart program. WM Northwest collects bagged leaves on the regular garbage day during the first full week of November, December, and January (three weeks total per season). Outside that window, yard waste goes in the garbage cart (within weight limits), self-haul to the WM Kennewick Transfer Station, or backyard composting. Outdoor burning of yard waste is regulated by the Washington Department of Ecology and the Benton Clean Air Agency; burning is generally prohibited inside urban growth areas where alternatives exist.
Kennewick's residential yard-waste program is narrower than the year-round green-cart programs found in western Washington cities. Per WM Northwest's published Kennewick service information, bagged leaves are collected on the regular weekly garbage day during the first full week of November, December, and January only - three weeks total per winter season. Leaves must be tied in standard-size lawn-and-leaf bags and placed alongside the garbage cart (not in it). Branches, grass clippings, and other yard waste outside the three-week leaf window go in the regular garbage cart (subject to the 65-pound weight limit per 32-gallon cart) or to self-haul at the WM Kennewick Transfer Station, or can be composted on-site. Outdoor burning of yard waste is heavily restricted. RCW 70A.200.040 and WAC Chapter 173-425 prohibit residential yard-waste burning inside urban growth areas where the Department of Ecology has determined reasonable alternatives are available - Kennewick lies inside the Tri-Cities Urban Growth Area, so residential yard-debris burning is generally prohibited. The Benton Clean Air Agency administers local burn-permit and burn-ban authority. Outside urban growth area boundaries, burn permits may be required from the Washington Department of Natural Resources under RCW 76.04.660 (forest-protection authority over fire hazards on land within DNR jurisdiction). Even where burning is allowed, the burn cannot include rubber, plastic, asphalt, garbage, dead animals, petroleum products, or paint, and is suspended during burn bans called by the Benton Clean Air Agency or the Tri-Counties Fire Marshal.
Putting yard waste at the curb outside the three-week winter leaf-collection window is not collected; bags left out can be cited under KMC 9.48 property-blight provisions if they accumulate. Illegal outdoor burning of yard waste inside the urban growth area is enforced by the Benton Clean Air Agency under WAC Chapter 173-425 and RCW Chapter 70A.200 (Waste Reduction, Recycling, and Model Litter Control Act), with civil penalties up to $10,000 per day per violation under RCW 70A.15.3160 (Washington Clean Air Act). Forest-jurisdiction burning that creates a fire hazard is enforceable by the Department of Natural Resources under RCW 76.04.660, including summary abatement and cost recovery. Burning prohibited materials (plastic, rubber, garbage) is a separate violation regardless of location.
