Most remodel and cleanout debris can go in. The limits come from Washington's disposal rules and from the Whitman County site that takes your load.
Whitman County has banned several items from its landfills since January 1, 2010. That list covers TVs, computer monitors, computer towers, laptops, and compact fluorescent and tube bulbs. Pull those out before you load.
Hazardous waste, liquids, paint, solvents, fuel, motor oil, and pesticides can't go in a standard dumpster either. Whitman County residents can drop household chemicals at the county's hazardous waste counter at no charge, Monday through Saturday, 8 a.m. to 4 p.m. Electric vehicle batteries aren't accepted there.
Asbestos needs special handling and must be declared ahead of time. Tires are charged by the piece, so mention them when you book.
If you're unsure about anything, check with your account manager before it goes in the container.
