  1. Conversion Technologies • Why CTs? • Some Facts: • 48% Diversion Rate • 170 Composters 8.1 M Tons/yr • 3.2 M tons ADC use in 2002 25 million tons of organics still being landfilled!!!!

  2. Conversion Technologies • 40117. “Gasification” means a technology that uses a noncombustion thermal process to convert solid waste to a clean burning fuel for the purpose of generating electricity, and that, at minimum, meets all of the following criteria: • (a) The technology does not use air or oxygen in the conversion process, except ambient air to maintain temperature control. • (b) The technology produces no discharges of air contaminants or emissions, including greenhouse gases, as defined in subdivision (g) of Section 42801.1 of the Health and Safety Code. • (c) The technology produces no discharges to surface or groundwaters of the state. • (d) The technology produces no hazardous waste. • (e) To the maximum extent feasible, the technology removes all recyclable materials and marketable green waste compostable materials from the solid waste stream prior to the conversion process and the owner or operator of the facility certifies that those materials will be recycled or composted. • (f) The facility where the technology is used is in compliance with all applicable laws, regulations, and ordinances. • (g) The facility certifies to the board that any local agency sending solid waste to the facility is in compliance with this division and has reduced, recycled, or composted solid waste to the maximum extent feasible, and the board makes a finding that the local agency has diverted at least 30 percent of all solid waste through source reduction, recycling, and composting.

  3. Conversion Technologies • Proposed Definition (regulations): • Noncombustion thermal, chemical, or biological processes of solid waste, including organics and plastics • Organic materials: • Paper & yard trimmings • Wood wastes & agricultural wastes • To extent feasible, all recyclable materials and marketable green waste compostables are removed • Owner/operator certifies that materials will be recycled or composted

  4. UC Tech. Evaluation • Develop specific and discreet definitions/descriptions for each CT evaluated • Evaluation of technical performance, feedstocks, emissions, residues • ID cleanest, least polluting CT

  5. CT Studies • Lifecycle/Market Impact Analysis • Description of lifecycle environmental/public health impacts of CTs • Compare to other solid waste management methods • Describe and evaluate impacts of CTs on recycling and composting markets

  6. Study Timeline • UC Tech. Evaluation Report • Draft to staff this week • UC Peer Review ASAP • Public Workshop April 14 in Sacramento • LCA/MIA Report • Draft to staff in early March • OEHHA/DTSC Review in early March • Peer Review in early March • Public Workshop April 15 in Sacramento

  7. Proposed Regulations • Establish permit tiers • Similar to current Transfer/Processing regs • Limited Volume (<15 T/Day) = Notification • Medium Volume (≥15 T/Day) = Registration • Large Volume (≥100 T/Day) = Full Permit

  8. Proposed Regulations • CTs must comply with SMS • CTs that pass 3-part test not subject to regulation • Registration and Full Permit Tiers require monthly inspections by EA • Must comply with all other local and state permits

  9. Proposed Regulations • Defines distillation, hydrolysis, and pyrolysis, • Above terms in definition of “Transformation” but not defined individually • Official Public Notice – March 2004
