Delisting Treatment

US Ecology’s delisting treatment process converts hazardous inorganic wastes into non-hazardous, delisted residuals.  Once your waste is delisted, it is no longer considered RCRA hazardous, eliminating your liabilities as well as minimizing other long-term risks associated with disposal.   

US Ecology is the only commercial treatment company in the U.S. that is USEPA-authorized to delist 15 inorganic hazardous wastes.  Delisting can be used on waste generated from both specific and nonspecific sources. 

Wastes that may be delisted include those designated under the land ban rules with the following codes:

  • K002 – K008
  • K062
  • F006 – F008
  • F011
  • F012
  • F019  

US Ecology is also able to treat 10 characteristic wastes (D002 – D011) to non-hazardous standards.  This treatment is not considered delisting because they are not listed wastes.   

The actual delisting process US Ecology uses is proprietary; however, the process involves conducting a series of reactions using wastes and reagents to neutralize the waste, precipitate the metals and create insoluble metal compounds.  Throughout the process, data integrity is crucial; elaborate and highly redundant detailed testing procedures ensure that all material leaving each US Ecology facility is in strict accordance with the delisting granted by the USEPA.  

Once the treatment residue has passed closely monitored quality control procedures it can be shipped to a non-hazardous landfill for proper disposal.  Documentation is then sent to the EPA showing the laboratory test results and place of disposal.  The generator also receives a certificate demonstrating that the waste has been rendered non-hazardous.  

Benefits of Delisting

Delisting standards are much more aggressive than the standards for normal treatment meaning your waste is more secure.  US Ecology’s insurance and indemnification programs stand behind our delisting ability.  We take responsibility for properly treating the waste and go one step further with indemnification to our customers that we have done our jobs.  This gives our customers long term security that no one else can offer.  

Delisting offers significant economic advantages as well.  Waste that has been delisted can be deposited in non-hazardous landfills – a less expensive, generally more available alternative to hazardous waste landfills.   

This attractive, safe and compliant disposal option is offered at our facilities in Canton, OH, York, PA and Harvey IL.
