If a facility generates hazardous waste in quantities of less than 100 kg (220 pounds or approximately 25 gallons) or is the generator of acutely hazardous waste in quantities of less than 1 kg (2 pounds) in a calendar month, that facility is defined, under Delaware’s Regulations Governing Hazardous Waste, as a conditionally exempt small quantity generator (CESQG).

Disclaimer: The information below is intended to serve as a guide to responsible waste management and does not supersede Delaware’s Regulations Governing Hazardous Waste (7 DE Admin. Code 1302). Regulations specific to Conditionally Exempt Small Quantity Generators can be found in the regulations.
The helpline, 302-739-9403, is available weekdays, from 8:00 a.m. to 4:30 p.m. Your calls, concerns or questions will be handled by a hazardous waste information expert.
To ensure compliance with the Regulations, and maintain conditional exemption, a small quantity generator must:
Identify the hazardous waste generated. Generators are responsible to determine if the waste generated is hazardous. This responsibility may simply be met by using knowledge of the product that becomes a waste or may be as involved as conducting analytical testing to determine that the waste is not contaminated.
Do not accumulate more than 31,000 kg (2,200 pounds or approximately 300 gallons) of hazardous waste or 1 kg (2.2 pounds) of acutely hazardous waste on your property at any given time. Generators who accumulate quantities of hazardous waste in excess of 1,000 kg (2,200 pounds or approximately 300 gallons) or 1 kg (2.2 pounds) of acutely hazardous waste are required to fulfill more stringent requirements of the Delaware Regulations Governing Hazardous Waste.
Maintain documentation demonstrating the hazardous waste has been managed appropriately. Documentation includes bills of lading, receipts, manifests, etc. Documentation of proper hazardous waste management must be maintained for a minimum of three years.
Properly manage and dispose of hazardous wastes. Hazardous wastes must be managed by a treatment, storage, or disposal facility permitted or approved by the State of Delaware to accept the waste.
Conditionally Exempt Small Quantity Generators are not required to notify the State of hazardous wastes they generate. However, DNREC recommends that they complete an EPA Site Identification Form.
