Auto Repair Shops generate hazardous waste that must be managed in accordance with Delaware’s Regulations Governing Hazardous Waste. Hazardous waste mismanagement adversely impacts human health and the environment.
Compliance and Permitting Section
302-739-9403
Improper disposal of hazardous waste, such as introduction to the municipal wastewater stream or putting hazardous waste in the municipal trash, is dangerous and against the law. Before discarding any waste, it is your shop’s responsibility to make a proper hazardous waste determination and to manage the waste accordingly.
This information is intended to serve as a guide to responsible waste management for auto repair shops. It is meant for Very Small Quantity Generators (VSQG) of hazardous waste and does not supersede Delaware’s Regulations Governing Hazardous Waste (7 DE Admin. Code 1302).
When handling these hazardous wastes, it is important to follow best practices:
Appropriately label waste containers (e.g., “Hazardous Waste”).
Keep containers closed, except when adding or removing waste.
Where possible, use detergent or water-based cleaners.
Do not mix used oil with hazardous waste.
Do not treat waste on site without a permit (e.g., air dry).
When possible, recycle or reclaim items for re-use.
Store flammable, reactive, and combustible materials in a fireproof container.
Block off or close floor drains to prevent releases.
When working with liquids, use a drain pan to capture spills and drained fluids.
Store waste in well maintained containers, compatible with the waste.
Avoid accumulating more than 1,000 kilograms (≈2,200 pounds) of hazardous waste or 1 kilogram (≈2.2 pounds) of acute hazardous waste.
The lists below identify some, but not all, of the items that should be evaluated prior to disposal.
