  1. Bark Beetle Waste DisposalMethods and Diversion Presented by County of San Bernardino Solid Waste Management Division for the California Integrated Waste Management Board September 17, 2003

  2. Bark Beetle Waste Volume • December 2002 – 100 tons per month • March 2003 – 600 tons per month • April 2003 – 600 tons per week • August 2003 – 600 tons per day • Total Tonnage Received To Date: more than 60,000 • Total Waste Tons Anticipated: 1,500 TPD for five years (includes SCE and Caltrans projects)

  3. Waste Disposal Methods • Initially, treated as trash due to low marketability • Current Methods: • Chipping and Grinding at Heaps Peak Transfer Station • Erosion Control at Landfills • Colmac Energy (biomass facility) • Compost Facilities • Alternative Daily Cover

  4. Chipping and Grinding Operation Heaps Peak Transfer Station Transfer Building Landfill Gas Building Processed Bark Beetle Waste (chipped material) - 300 tons Portion of incoming Bark Beetle Waste (raw material) 1,000 tons of material In-Line Grinder • Permitted for 300 TPD trash; normally averages 150 TPD of trash. • Currently averages 400 TPD of Bark Beetle waste, 150 TPD trash • Currently operating under an emergency waiver.

  5. Waste Disposal Methods(continued) • Air Curtain Destructors • Burns wood waste; 250 TPD capacity • Averages 7 tons per hour each incinerator • Operates 24 hours per day, 6 days per week • Ash byproduct land filled (researching markets for ash and methods to combine dirt with ash for ADC) • In process of purchasing third burner for total site capacity of 450 TPD

  6. Air Curtain Destructor Processing Burnt Flats Wood Waste Processing Facility Air Curtain Destructors

  7. Diversion Methods • Log Sorting and Storage Area • Developed for private companies to store logs, prepare for transport to sawmill • Only one sawmill within economic range • That sawmill dropped the price it would pay for logs July 2003 • Result was fewer logs being diverted to sawmill; volume for County disposal increased by 1,300 tons per week • Private pallet manufacturer on site within 60 days; expected to process 2 million board feet per month, or 300 TPD • Portable milling activities expected to increase due to joint venture program with CDF and economic incentive grant from USFS

  8. Log Storage and Staging Area 15 acres - Lake Arrowhead, CA Mowbray’s Tree Service (SCE Contractor) Evergreen Resource Mgmt (w/portable mill operations) Future Pallet Mill Pallet Masters - LA All American (w/portable mill operations) Paul Bunyan Hawaiian Tree Service (to be relocated to make room for Pallet Mill) Great Scott SCE Job Trailers

  9. Future Diversion Programs • Utilizing inactive Cajon Landfill • Cajon Landfill is near railroad spurs and major freeways • Log Storage and Processing • Chipping for erosion control • Chipping for shipment to Paper Mills (requires specified chip product) • Request for Proposal for Sawmill (3 million board feet per month +), release in October 2003 • Other Log Storage and Division as Necessary • Working cooperatively with RWQCB and LEA for reuse of Cajon for this purpose • SCE Considering Separate Disposal/Diversion Yard and Biomass to Energy Plant possible 2 years out

  10. The Costs • Spent $1 million FY 02 / 03 • Expected $4 million FY 03 / 04 • Expected $6 million each year for next 5 years • Hoping to create more diversion to reduce disposal costs; transportation largest cost factor • Few end uses of pine • Looking for assistance in creating additional diversion programs and/or grants to help off-set existing disposal and diversion programs
