For how long can a generator accumulate hazardous waste onsite without a permit?

A generator can accumulate hazardous waste onsite without a permit for a maximum of 90 days. This time frame is established under regulations set by the Environmental Protection Agency (EPA) and relevant state guidelines to ensure that hazardous waste is managed in a safe and environmentally sound manner.

This 90-day accumulation period allows generators to store hazardous waste temporarily while ensuring that it is properly treated, recycled, or disposed of within that time. After the 90 days, the generator would be required to follow stricter regulations for the management of hazardous waste, which typically involves obtaining a permit or having the waste removed to a proper disposal facility. Understanding this time limit is crucial for compliance and for minimizing risks associated with hazardous waste storage.

The other time frames mentioned do not align with the regulations set forth for hazardous waste accumulation, which is why they are not considered correct answers.
