Most construction, demolition and household debris is acceptable, and Erie County publishes its prohibited list in full, which makes this unusually easy to be precise about.
The county landfill does not accept free liquids of any kind, with a narrow exception for liquids that pass a paint filter test. It does not accept refrigerated appliances, which covers refrigerators, freezers, dehumidifiers and air conditioners. Lead-acid batteries and yard waste are both excluded and both have their own recycling route in the county.
Asbestos waste is prohibited outright, as is contaminated biomedical waste, radioactive waste, and anything that is a listed hazardous waste or shows hazardous characteristics under the federal rules. Cathode-ray tube televisions are named and excluded, so an old set from a basement clearance cannot go in.
Ohio also bars whole tires from landfill statewide, so tires come out of a load and go to a recycling route. And where the acceptability of a material is questionable, the county requires a solid waste disclosure questionnaire to be completed and approved before disposal, which is a step your account manager will handle rather than leaving you to discover it at the gate.
One preparation rule is worth knowing on a demolition job. Wooden railroad ties, guard rail posts, fence posts and telephone poles all have to be cut to no longer than four feet before the landfill will take them. Cutting them on site is free; having a load turned away is not.
