For large quantity generators, what is the maximum storage time allowed for hazardous waste without a permit?

For large quantity generators (LQGs) of hazardous waste, the regulations stipulate that they can accumulate hazardous waste on-site without a permit for a maximum of 90 days. This period is specifically designed to ensure that waste is managed effectively while balancing the need to facilitate operational flexibility for businesses generating hazardous waste. Beyond this time frame, LQGs are required to either treat, store, or dispose of the waste properly or obtain the necessary permits for longer-term storage.

The 90-day limit is important because it encourages timely waste management practices and helps minimize the potential environmental impact that could arise from holding hazardous waste for extended periods. This provision is carved out under the Resource Conservation and Recovery Act (RCRA), which outlines the framework for managing hazardous waste in the United States.

Understanding this regulation is crucial for those managing hazardous waste to ensure compliance and to promote safety in waste handling and management activities.
