Frequent Questions

What are the recordkeeping and notification requirements for conditionally exempt small quantity generators (CESQGs)?

Although CESQGs are not subject to recordkeeping, including notification, biennial reporting, and manifest requirements, they are still subject to limited generator waste management standards.  40 CFR §261.5 sets forth the special requirements for hazardous waste generated by the conditionally exempt small quantity generators.

However, some states may require recordkeeping or collect data on CESQGs through inspections, you should contact your state environmental agency for guidance on CESQG recordkeeping requirements.

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.
