Dangerous waste basics

Businesses that generate any amount of dangerous waste are responsible for this waste from cradle to grave. In Washington state, the Dangerous Waste Regulations determine what dangerous waste is, and how businesses should properly handle and dispose of it.

For most businesses, the process will involve these basic steps:

Designation (determine if your waste is dangerous)
Determine your generator category (small, medium, or large)
Proper containment and labeling
Recordkeeping
Waste disposal or recycling
Reporting and possible fees

This page offers some introductory videos, publications, and posters to help you better understand the basics of dangerous waste management.

What is dangerous waste?

Washington state uses the term "dangerous waste" rather than the federal law's term of "hazardous waste." This is because Washington state's Dangerous Waste Regulations are more protective than federal laws. The definition of "dangerous waste" is more expansive than "hazardous waste."

What are the Dangerous Waste Regulations?

The regulations are based on the federal Resource Conservation and Recovery Act (RCRA), but are more protective. You may find the regulations in the following formats:

How to designate your waste

How to manage dangerous waste containers

Dangerous waste containers must be kept closed except when adding or removing waste. Open containers are one of the most common violations our inspectors find.
