Headquarters landfill is currently the only operating Municipal Solid Waste Landfill (MSWL) in the County, permitted under WAC 173-351. It was developed by Weyerhaeuser as a Limited Purpose Landfill (LPL), for disposal of industrial timber wastes in 1993. Cowlitz County updated the Solid Waste Management Plan in 2011 to include the facility. Plans to buy the property from Weyerhaeuser began soon after. By November 2013, Headquarters landfill was owned by Cowlitz County and permitted as a MSWL. The landfill accepts municipal solid waste, normal non-hazardous household waste, and some industrial and commercial wastes. Headquarters will eventually comprise a 308-acre footprint with an estimated site capacity of 54.8 million cubic tons of waste.
