DEEP: Small Quantity Generators

Small Quantity Generators (SQGs)

What is an SQG?  An SQG generates more hazardous waste than a Conditionally Exempt Small Quantity Generator (CESQG) and therefore has more hazardous waste requirements to comply with than a CESQG, but fewer requirements than a Large Quantity Generator (LQG).  A generator qualifies as a SQG if it meets all of the following conditions:
  • generates between 100 kilograms (220 pounds) and 1000 kilograms (2200 pounds) of hazardous waste per calendar month; and,

  • never accumulates more than 1000 kilograms (2200 pounds) of hazardous waste at any one time; and,

  • does not generate more than one kilogram (2.2 pounds) of acute hazardous waste per calendar month; and,

  • does not accumulate more than one kilogram (2.2 pounds) of acute hazardous waste at any one time.
For a typical liquid waste, 100 kilograms (220 pounds) equals about half of a 55-gallon drum.  For more dense wastes such as solids and sludges, 100 kilograms can be much less than half a 55-gallon drum.

Note:  Certain wastes (such as Universal Wastes) are not counted towards the quantity limits specified above.  For details on how to properly determine generator status, please see the DEEP fact sheet Determining Hazardous Waste Generator Category or the RCRA Help! Webpage.

Compliance Assistance Tools for SQGs  Listed below are several web pages and guidance documents that are helpful in assisting SQGs to properly manage hazardous wastes and other, related waste materials.
  • Hazardous Waste On-Line Training Course:  This is an Internet-based training course that provides detailed instruction in hazardous waste requirements for small and large quantity generators.

  • Notification of Regulated Waste Activity form  [Exit DEEP website]  Form that an SQG must fill out and submit to DEEP when the begin operating as an SQG.  This form should also be re-submitted to DEEP when certain changes occur, such as the name or ownership of the facility (see the instructions that accompany the form for details).

  • Small Quantity Generator Handbook  Detailed information on how SQGs must manage their hazardous waste, presented in a convenient booklet format.

  • Small Quantity Generator Training Materials To assist SQGs in ensuring that their employees are properly trained to become thoroughly familiar with the applicable hazardous waste requirements relevant to their duties (which would include but not limited to waste handling, marking/labeling, preparing manifests, conducting inspections, emergency coordination and response, etc.). Below are links to the materials used during DEEP-sponsored workshops which took place in federal fiscal year 2010.
