Hazardous Waste

Delisting a Hazardous Waste

The Hazardous Waste Identification Process: Step 4 - Is the waste delisted?Click on a step in the hazardous waste identification process for more information.

The Resource Conservation and Recovery Act (RCRA) provides a process to remove, or “delist,” a waste generated at a facility from the list of hazardous wastes.

The regulations describing the delisting process are found in Title 40 of the Code of Federal Regulations (CFR) in section 260.22.

This delisting process is initiated by the generator (the person who creates the waste), who prepares a petition for delisting the waste.

What is a Hazardous Waste Delisting?

RCRA regulations provide a petition procedure to exclude or "delist" a particular facility's waste from the list of hazardous wastes if the waste does not possess the dangerous properties. While there are two general types of hazardous waste, characteristic and listed, only listed wastes can be delisted. 

  • Characteristic hazardous wastes are designated hazardous because they exhibit dangerous properties such as corrosivity, ignitability, reactivity, or toxicity. Characteristic hazardous wastes cannot be delisted because of these dangerous properties.
  • Listed hazardous wastes are designated hazardous because the processes that generate them have typically produced wastes with dangerous properties like those mentioned above for characteristic wastes. Listed wastes are presumed to possess dangerous properties because of historical knowledge of the waste-generating-process.

How Do I Get a Delisting for My Waste?

This delisting process is initiated by the generator (the person who creates the waste), who prepares a petition for delisting the waste. The petition provides information about the waste, including its chemical composition, to demonstrate the rationale for delisting the waste. The petition is reviewed by the appropriate regulatory agency -- either U.S. EPA or an authorized state hazardous waste regulatory agency -- to determine whether the waste should continue to be listed as hazardous.

To begin this process, the hazardous waste generator must determine to whom they must petition, the U.S. EPA regional office or the state environmental agency. U.S. EPA delegated the authority to delist hazardous waste generated and disposed of in certain states to the state environmental agency. The delisting process is different in each U.S. EPA region and in each state so it is key to contact your regional or state coordinator and discuss the delistings process with him or her first. Below is a listing of regional and state delistings coordinators:
