Comparison: State vs. Federal
• Rules. Washington follows the federal requirements for emergency planning and response and requires that all emergencies be reported to both state and local authorities. To review emergency reporting requirements, refer to the national section EMERGENCY PLANNING AND RESPONSE.
Large quantity hazardous waste generators are required to prepare an emergency preparedness plan, and in addition, they are required to have an emergency response coordinator. Small quantity generators are not required to have an emergency preparedness plan but need to designate an emergency response coordinator. For additional information on generator responsibilities, see the national section GENERATORS. For information on the preparation of a hazardous waste site contingency plan, see the state section CONTINGENCY PLAN.
