Total Waste Tons Anticipated: 1,500 TPD for five years (includes SCE and Caltrans projects)

Waste Disposal MethodsWaste 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

•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.

Diversion MethodsDiversion 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

Future Diversion ProgramsFuture 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

The CostsThe 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
