King County residents can safely and conveniently dispose of old car batteries, oil, paint thinner and other household hazardous items at no cost when the Wastemobile comes to Carnation, 10 a.m. to 5 p.m. daily Aug. 19 to 21. The Wastemobile will be at Tolt MacDonald Park, on the 3600 block of Tolt Avenue, each day.

Drop off such hazardous waste items as pesticides, oil-based paints, oil, antifreeze, car lamps, fluorescent bulbs and tubes and other items without a charge. The service is pre-paid through garbage and sewer utility fees.

Created in 1989, the Wastemobile was the first traveling hazardous waste disposal program in the nation. It is operated by the Local Hazardous Waste Management Program and goes throughout the county from the spring through fall.
