Most job-site and household debris loads fine. The limits come from Nebraska law and from what the City transfer station will accept.
Nebraska bans six categories from every landfill in the state. The state's environment and energy department lists them as yard waste from April through November, waste oil, lead-acid car batteries, household appliances, hazardous waste beyond household quantities, and waste tires. Appliances cover washers, dryers, water heaters, air conditioners, refrigerators, freezers, dishwashers, ranges, stoves and more, and any refrigerant has to come out first.
Hazardous waste, liquids, paint, solvents, fuel and asbestos stay out of every delivered container. The transfer station is firm on asbestos in particular, and it takes none at all.
Norfolk adds a size rule that catches people out. Because loads are reloaded into transfer trailers, the station limits individual pieces to roughly 20 pounds and 8 feet in length for lumber and for iron and steel, and countertops and cabinets have to come in under 8 feet as well. Long framing lumber and full sheets need to be cut down before they go in.
If you have an item you are unsure about, raise it with your account manager before loading.
