Dangerous wastes are materials that require special care when being recycled or disposed of to protect public health and the environment. Businesses in Washington are responsible for managing their own dangerous waste and are subject to rules from the Washington State Department of Ecology and local government. The regulations vary depending on how much dangerous waste is generated. To help you understand the regulations that apply to your business, the Department of Ecology has created a Guide to Dangerous Waste by Generator Category.
Small quantity generators (SQG) may be exempt from Ecology’s regulations and have several local options for dangerous waste recycling and disposal. To determine if you have SQG designation, follow the Department of Ecology’s waste generator categorization process. If you are designated an SQG, Clark County Pollution Prevention Assistance program can provide hands-on pollution prevention advice and regulatory assistance.

Tips for storage, recycling, and disposal
Avoid stockpiling dangerous waste: Stockpiling dangerous waste can have serious consequences, such as spills and chemical reactions. Additionally, accumulating over 2,200 pounds of dangerous waste at any time will turn your business into a medium or large quantity generator, making your business subject to the full extent of the state regulations.
Inspect and store containers safely: Only use storage containers that are compatible with the waste inside. Label all storage containers and follow storage requirements, such as temperature and secondary containments. To avoid accidental mixing or spills while storing or transporting, inspect the containers regularly for leaks, cracks, or corrosion.
Empty containers may be considered dangerous waste: Containers that once held a hazardous substance may need disposal as a dangerous waste. Be prepared to leave the containers at the disposal location.
Universal waste, product stewardship, and private recyclers
Small businesses have recycling options for specific dangerous wastes through product stewardship laws, universal waste rules, and private recyclers. Recycling these items is often more cost effective than disposing of them as dangerous waste. See below for recycling options for specific materials and products. Always call ahead as these options are subject to change without notice, and additional rules or restrictions may apply. Fees apply unless otherwise stated.
