The Department of Ecology adopted amendments to Wash. Admin. Code §173-303, Dangerous Waste Regulations. The dangerous waste rules set forth waste management standards for all Washington state dangerous waste generators, transporters, and facilities. Federal rules were incorporated and state-only requirements were updated, including modifying pre-permit application requirements for siting criteria, updating publications on Chemical Test Methods and Biological Testing Methods 80-12, and various clarifications and corrections. http://apps.leg.wa.gov/documents/laws/wsr/2009/14/09-14-105.htm.
