Containers or container liners (glass or plastic bottles, cardboard boxes, etc.) which have held non-acute* hazardous materials are not regulated as hazardous wastes if all removable wastes have been emptied. For a container to be considered empty, the following conditions must be met.
A container holding non-acute* hazardous waste is empty when all wastes have been removed using practices commonly employed industry-wide to remove wastes from containers or liners, such as pouring, pumping, and aspirating, AND when draining...
If a container cannot meet the specifications listed above, it must be disposed of a chemical waste.
*Empty containers which held P-listed wastes are considered "acute" wastes. Fill out a chemical pickup form for disposal of empty containers of these chemicals. The P-list can be found at the following link: http://www.epa.gov/osw/inforesources/data/br91/na_apb-p.pdf
Empty containers that held non-acute (see above) materials may be disposed of as non-hazardous waste, i.e., using the same method as would be used for disposing of clean glass, plastic, cardboard, etc. containers.
For empty glass bottles, please place the bottles in a rigid cardboard box that is taped shut and marked for disposal to ensure the safety of the housekeeping staff in case the bottles break.
