A hazardous waste (HW) determination must be made of any waste material generated (40 CFR 262.11). HW must be recycled, treated, stored, or disposed at a proper HW facility. HW cannot be disposed on or in the ground, or in local landfills, septic tanks, or injection wells. Also, regardless of quantity, the generator of HW is ultimately responsible for the waste from "cradle to grave," and can be held liable for improper management of HW even though it may have been sent to a "proper" HW management facility using a licensed transporter. Typical HW include used oil, used oil filters, paint waste, photographic waste, fluorescent lamps, mineral spirits, printing inks, pharmaceuticals, blasting media, lead-acid batteries, and the list goes on.
