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) More processing = higher cost • 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 6

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

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

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

Preferred use of Green and Wood Waste Municipal Compost Soil Amendment/Vermicompost 10

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
