Oklahoma Latest to Adopt Aerosols as Universal Waste Final Rule


At large retail facilities, aerosols have accounted for up to 40% of the items managed as hazardous waste which has led the Environmental Protection Agency (EPA) to add aerosol cans to the federal universal waste list. This rule allows generators to manage aerosol products with the less complicated universal waste requirements and as a result, enables retailers to significantly reduce how much hazardous waste they are generating.

Additionally, the following outlines the state-by-state implementation of the Aerosols as Universal Waste Rule, focusing on changes over the past month.
