Dangerous waste guidance

Many businesses in Washington generate some type of dangerous waste — waste that’s potentially harmful to peoples' health and the environment. You are required to determine whether the waste your business generates is dangerous. You must also handle your dangerous waste safely and dispose of it properly.

Knowing whether you have dangerous waste, how much you have, and the rules you have to follow is a process. To properly manage your waste, you must:

• Designate your waste - is it dangerous?
• Count your waste — how much do you generate each month?
• Determine your generator category — are you a small, medium, or large quantity generator?
• Use proper containment — keep containers closed and use secondary containment.
• Label dangerous waste properly — use our free labels.
• Dispose, recycle, or treat your dangerous wastes — you are responsible from cradle to grave.
• Complete your Dangerous Waste Annual Report — if you have an active EPA/State ID number.
