The Current Aerosol Can Hazardous Waste Regulation
Aerosol cans, when discarded, are handled as hazardous waste. Entities with these are required to follow all hazardous waste rules regarding them. The number of days you can store these cans ranges from 90 to 270 depending on generator status and transportation. Retail stores who discard aerosol cans must also follow all hazardous waste rules. In some states, generators can recycle the cans for scrap metal by puncturing them and draining the contents into other containers. The can becomes non-hazardous, but the container of leftovers may be considered hazardous waste. Some states don’t allow the puncturing and recycling of cans at all, even under carbon filtration.
The Proposed Aerosol Can Hazardous Waste Regulation
The proposed regulation would make discarded aerosol cans a universal waste. Other EPA universal wastes include batteries, mercury-containing equipment, and hazardous waste mercury lamps. Universal wastes can be stored and collected for up to one year and don’t need a hazardous waste manifest as long as they’re properly packaged and labeled.
As for aerosol can recycling, the proposed rule would encourage generators to collect and send their cans to a centralized hazardous waste handler for recycling. Any company recycling aerosol cans would be subject to special requirements. Only approved commercial devices for safely puncturing cans could be used. These facilities would also be required to have written procedures for operations and maintenance of the machines, how incompatible wastes would be segregated, proper hazardous waste management practices to be followed, and what emergency spill procedures would be followed.
EPA’s intent is to ease the retailer’s burden of managing aerosol can as hazardous waste, ease the generators’ burden of managing aerosol cans as hazardous waste, and to encourage more states and more entities to recycle aerosol cans.
There are still some gaps and unknowns within the regulations such as: What is the exact definition of an aerosol can, that is, would cans that do not aerate (such as shaving gel cans), be included? At what point between full, empty, “RCRA empty”, and used would the cans be eligible for universal waste consideration? Should there be a size limit on the cans; would cylinders be included? Would the equipment that some generators have already invested in to puncture and recycle their own cans be suitable under the new regulation?
