Hazardous waste service providers

Hazardous waste service providers (or, waste service providers) are companies that dangerous waste generators hire to help them: 

  • Transport waste.
  • Dispose of waste.
  • Designate or identify waste codes.
  • Create hazardous waste manifests.
  • Assist with recordkeeping.

Do you have to hire a waste service provider?

This depends on your generator category:

  • Medium and large quantity generators (MQGs and LQGs)
    Must hire a waste service provider to handle, transport, and dispose of their dangerous waste.
  • Small quantity generators (SQGs)
    Can choose to hire a waste service provider, but it’s not required. SQGs may also choose to transport their own dangerous waste to an appropriate disposal facility themselves.

What waste service providers are available?

The table below lists commonly used permitted and non-permitted waste service providers in Washington. It describes the type of dangerous waste they handle and links to the company’s Enforcement and Compliance History Online (ECHO) record.

Waste service providers must adhere to all state and federal laws that apply to them, but only those operating a permitted dangerous waste facility (also referred to as TSDs, TSDRs, or TSDFs, which stands for some combination of Treatment, Storage, Disposal, or Recycling Facilities) are required to have a dangerous waste permit issued by the Department of Ecology.

Note: We do not endorse any company. This list is not exhaustive. You could also search online to find even more hazardous waste service providers near you. Before you choose a company, be sure to follow our guidance on how to choose a waste service provider.

How do you choose a waste service provider?

Consider balancing cost, liability, and service to find the right provider for your business. If you use a service provider that does not manage your waste properly, you are liable for the consequences, which could result in spendy cleanup costs.

What to research about a waste service provider


Detail your scope of work and costs

Specifically, the unit and cost you want to see. For example, $/gallon or $/pound. Put all your expectations for costs, services, compliance record, and financial assurance into your scope of work. A clear, detailed scope of work can help you get bids that are comparable.
