Dangerous waste basics
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:
- Online (searchable by topic or keyword).
- Email us for a free printed and bound copy.
- Download a PDF.
