The Department of Ecology proposes to amend Wash. Admin. Code 173-350, which pertains to the handling of recyclable hazardous materials by waste facilities. Proposed changes include new exemptions for organic materials and definitions for take-back centers. The Department is also considering the repeal of 173-345, which sets the minimum standards for transporters of hazardous waste. According to the Department, changes are necessary to promote organic recycling and provide exemptions for compost. http://apps.leg.wa.gov/documents/laws/wsr/2010/12/10-12-051.htm.
