Conditionally excluded wastes
The Dangerous Waste Regulations conditionally exclude some dangerous wastes. See excluded categories of waste at WAC 173-303-071. Excluded wastes remain solid wastes, but they are not subject to most of the dangerous waste rules, including counting and annual reporting requirements. Usually, the waste must meet a set of specific conditions in order to qualify for the exclusion.
These wastes may be excluded because:
- They are regulated under other state and federal programs.
- They are recycled in ways that don’t harm human health or the environment.
For example, a household hazardous waste exclusion removes household waste from dangerous waste regulation. Other exclusions include treated wood waste, polychlorinated biphenyls (PCBs), and waste reclaimed and reused in a closed loop system. Many other wastes are excluded in the regulations. The wastes mentioned here are some of the most common ones.
