Regulatory Agency

Washington Department of Ecology (WDOE) Hazardous Waste and Toxics Reduction Program

See national section for basic information and federal regulations.

Comparison: State vs. Federal

Rules. Washington has adopted the federal regulations for universal wastes, with the exception of the provisions relating to pesticides. Consequently, pesticides that are hazardous wastes must be managed under the state's dangerous waste rules. See the state section PESTICIDES for more information.

The state regulations include the federal rules for managing fluorescent lamps as a universal waste with additional and more stringent state provisions concerning definitions, indoor storage, notification, and accumulation quantity limits. Washington's rules for the regulation of mercury-containing equipment (MCE) as a universal waste follow, in most ways, the federal MCE provisions.

Administration and enforcement. The Washington Department of Ecology (WDOE) administers and enforces the universal waste rule in Washington.
