Not sure if your waste can go to the landfill?

Industrial waste such as contaminated soil can be dangerous and isn’t accepted at the landfill.

We can help. We use the Waste Disposal Authorization (WDA) process to determine if the waste is hazardous or non-hazardous so you can properly dispose in Pierce County.

Examples of wastes that need the WDA process:

  • Contaminated soils.
  • Industrial wastes (ash, slag).
  • Spent sandblast material.
  • Paint-booth filters.
  • Residue from steam-cleaning operations.
  • Grit and soil from carwash catch basins.
  • Certain asbestos waste.

Get a waste disposal authorization.

  • Submit a WDA application, payment and results of analyses performed on waste samples.

2019 fees

  • WDA review fee: $165.
  • Renewals and modifications: $90.

Next steps

We will review the application and let you know within three business days if you can dispose the waste in Pierce County. If accepted, we will issue the Waste Disposal Authorization. Conditions of approval vary.
