6. NRRWF’s Operational Considerations: 1) Grind to finer sizes & deliver to compost sites (if they will take it), or… 2) Grind the material for use as Alternative Daily Cover (ADC) ADC (instead of soil) Processed wood grindings in ADC can be used to cover buried garbage (but related organics laws may change) ADC is subject to State Board of Equalization fees ($1.40/ton) ADC does not perform as well as soil to cover garbage ADC is bulkier than soil More processing = higher cost 6

7. ADC used at NRRWF Chipped wood waste (ADC) transported and stored on landfill cell at a cost of $24/ton Height nearly 6 feet tall, area about the size of two football fields 7

8. ADC used at Landfill Working Face “Flagging” = protruding garbage Need to use a lot of passes to reduce flagging and improve compaction 8

9. Impacts of ADC on NRRWF Operations Costly to produce (on-site grinding) Costly to transport to fill areas Bulkier than cover soil to bury garbage Occupies air space (valued at $42.11/ton) Existing NRRWF financial model does not support current strategy for processed wood waste State law may eventually prohibit burial of organics (i.e. ADC) in landfills 9

10. Preferred use of Green and Wood Waste Municipal CompostSoil Amendment/Vermicompost 10

11. Options Considered Discontinue accepting green and wood waste at NRRWF o Direct customers to other facilities (i.e. compost sites) o Composting is a more beneficial use Increase minimum fee from $12/ton to $66.11/ton to process wood grindings and transport them to active fill areas o Cost of processing and grinding = $24/ton o Cost of disposal = $42.11/ton o Total cost = $66.11/ton 11
