Most construction and household debris is fine to load. California's hazardous waste rules and the local disposal sites set the limits.
CalRecycle, the state's recycling agency, says it's illegal to throw hazardous waste in the garbage. That covers batteries, fluorescent lights, paint and solvents, pesticides, antifreeze, motor oil, and propane tanks. Electronics, treated lumber, and asbestos are on the state's list too, and tires are banned from the trash even though they aren't hazardous.
Locally, the Authority's rate sheet shows that the Jolon Road station runs a free drop-off for Authority residents for antifreeze, batteries, motor oil, and latex paint, up to 5 gallons. Refrigerators cost $15.00 each because the refrigerant has to be removed, and ammonia-based appliances aren't accepted at all.
Concrete, asphalt, and clean fill dirt aren't priced at the King City station. They go to the Authority's landfill in Gonzales instead, with approval first. Liquids and fuel stay out of any standard dumpster.
If you're unsure about an item, ask your account manager before it goes in.
