Frequent Questions

Can generators keep Hazardous Waste Manifests and Biennial Report information off site?

Generators are not required to keep copies of manifests and biennial reports on site. Generators may keep copies at a corporate headquarters. However, the generator must be able to provide to EPA information on, or access to, these records (Monthly Call Center Report Question; April 1984, RCRA Online #12199).

Note: On November 28, 2016, EPA published the Hazardous Waste Generator Improvements Final Rule, which makes several revisions to the hazardous waste generator regulations. These revisions may affect the information provided in this FAQ. The final rule and additional information, including a fact sheet, frequent questions, and a webinar recording and slides, are available at

The Hazardous Waste Generator Improvements Final Rule is effective on May 30, 2017; however, implementation in a particular state depends on the state’s authorization status. A discussion of the effect that this final rule will have on state authorization is available on page 85801 of the rule. Information about how the rule will affect the requirements in this FAQ in a particular state is best obtained from the state hazardous waste program. A list of state hazardous waste programs is available at
