Material Classes in the Overall Disposed Waste Stream, 1999
Background• Strategic Plan calls for waste characterization
study every 4 years• First statewide study done in 1999• Budget Change Proposal (BCP) for large new
study was developed for 2002-2003 Fiscal Year (FY) but did not go forward
• Contract Concept for smaller statewide study approved Fall 2002 – study is now under way
• Updated BCP for larger study approved for 2003-2004 FY - $990,000 available
Contract Process and Timeline
• February 2004 Board Meeting – Board approved Scope of Work
• Request for Proposals issued March 1, 2004• Proposals received April 16, 2004• Staff evaluated proposals April 20 – 27,
2004• Proposal from Cascadia Consulting Group
received the highest score
Scope of Work
• Approach: target specific generators and sources of waste for study
• 4 areas selected for study– commercial sector generators– MRF residuals– Construction and demolition waste– Commercial self-haul
Overall Design
• Focus on major metropolitan areas
• Coordinate field work for all 4 parts – sampling locations, schedules
• Data collected for 2 seasons
• Field work conducted in 2005, data analysis and study report complete by June 2006
Target 1: Commercial Generators
• Method similar to one used in 1999 study• New approach:
– Target most important generators only– Collect disposal composition and diversion data– Design new generator groups as needed
• Data will update and expand waste characterization web database for use by local governments
Target 2: Materials Recovery Facility (MRF) Residuals
• Quantify and characterize residuals from Materials Recovery Facilities and Solid Waste Processing Facilities (clean and dirty MRFs)
• Develop listing and survey major MRFs• Classify into sampling groups• Field sampling and sorting of residuals for
each group
Target 3: Construction & Demolition Waste
• Develop reliable volume-to-weight conversion factors for detailed C&D material types
• Develop visual characterization method for CIWMB and local government use
• Use new method to characterize C&D waste
• Characterize 5 sources of C&D waste
Target 4: Commercial Self-Haul
• “Other commercial” (non-C&D) self-haul
• “Drop box” containers provided by haulers (non-C&D)
• Characterization of materials
• Identify sources and activities generating the waste
• Survey materials recovered from loads
Staff Recommendation
• Approve the award of the contract for Targeted Waste Characterization Studies to Cascadia Consulting Group, and adopt Resolution # 2004-144.
