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) 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
