Lumber, drywall, plaster, shingles, flooring, cabinets, doors, furniture, and household junk are all standard loads here. The limits come from the county's two sites, which publish what they will and will not take.
The transfer station in town has the tighter list. It turns away asbestos, industrial waste, concrete slabs bigger than 12 inches square, poles longer than four feet, metal pipe or steel that can be recycled, and shingle loads over seven tons. Those loads go to the county landfill instead, which is one reason your account manager asks what the debris is before picking a site.
Tires come out before loading. The county requires tires to arrive at the landfill separately and with approval first, and it charges extra if tires turn up buried in a mixed load. The transfer station does not take bulk tire loads at all.
Electronics and refrigerant appliances have their own route. TVs, computers, and computer accessories go to the landfill weigh-in office, and the transfer station no longer takes appliances that contain refrigerant. Pennsylvania's own guidance is blunt about why: the Department of Environmental Protection tells residents not to put old electronics in the trash because of the lead, cadmium, and mercury inside them.
Liquids, paint, solvents, fuel, used oil, batteries, and pressurized cylinders stay out of any container. The county even has a separate charge for a load that shuts the transfer station down, and excessive paint or liquid is on its list of causes. Ask your account manager about anything unusual first.
