Small Quantity Generator Self-Certification Program (SQG)
Small Quantity Generator Self-Certification and Declaration of Compliance

A small quantity generator (SQG) of hazardous waste is an individual or a company that generates or makes less than 220 pounds (100 kilograms) of hazardous waste in each and every month. The law requires each SQG to review their hazardous waste management procedures, conduct a self-inspection of their facility and certify compliance to NHDES every three years. Given the large number of hazardous waste generators in the state, NHDES has found self-certification and declaration of compliance to be the most effective way to regulate compliance at these facilities.

The self-certification process helps generators to learn which hazardous waste rules apply to them, and encourages generators to comply with those rules. After answering specific questions about how hazardous waste is managed at their facility, the facility owner signs a certification declaration affirming that the answers are correct and complete.

Anyone, individual or company, that generates or makes hazardous waste less than 220 pounds (100 kilograms) in each and every month must certify. State and municipal facilities at the SQG size must self-certify.

NHDES sends self-certification and declaration of compliance forms upon notification that a facility is generating at SQG amounts and on the renewal date for the county in which the facility is located. (See below for details.) In October of each year, NHDES sends self-certification forms to facility owners for them to complete and return by January 1 of the next year.
