Treatment, storage, and disposal facilities (TSDFs) are also required to make a report of the wastes they’ve received from off-site.

Your facility must complete biennial hazardous waste reports if you generate 2,200 lbs. of hazardous waste in any calendar month. You may have additional state requirements and thresholds to consider as well.

Biennial hazardous waste reporting typically applies to large quantity generators, but state regulations may vary for small quantity generators, conditionally exempt small quantity generators and other state-specific categories of generators.

These reports are sent to your authorized state agency or EPA regional office, depending on where your facility is located and your state rules.
