  1. UPDATE Proposed Rule 1133.3 – Emission Reductions from Greenwaste Composting Operations December 2, 2010

  2. Existing Air Quality • South Coast Air Basin • Non-attainment for PM2.5 (NH3 precursor) • Extreme non-attainment for Ozone (VOC precursor) • Contaminants contribute to significant adverse health effects

  3. Purpose • Control Measure of the 2007 AQMP • Element to meet the federal PM2.5 (2015) and Ozone (2024) standards • Focus to reduce air emissions while being sensitive to costs • Want to continue the practice of composting • Welcome input

  4. Schedule and Process • Two working group meetings to date • Site visits • Public workshop to be held • Additional working group meetings - TBD • Rule consideration – March 2011

  5. Universe of Sources • Number of facilities = 16 (as of 2009) • Total throughput ≈ 692,000 tons/yr Note: 2007 Survey – 13 facilities and 708,328 tons/yr throughput

  6. Emissions • VOCs: • 1,330 tons/year (3.6 tons/day) • NH3: • 300 tons/year (0.8 tons/day)

  7. Basic Concepts • Stockpile management to prevent inadvertent decomposition • Conduct green waste composting in turned windrows • Cover during active phase with finished material • Air pollution controls required for composting using increased amounts of food waste

  8. Key Input Received • Compliance costs & CEQA • Harmony with Rule 1133.1 (incl. exemptions) • Don’t disadvantage composting vs. other alternatives (e.g., landfills) • Effectiveness of controls & emission factors • Practicality of monitoring parameters • Consideration of static piles • Food waste volume vs. weight percent

  9. Concepts Under Consideration • Amending Rule 1133.1 – Chipping and Grinding for stockpile management • Do we need to monitor T, MC, O2, & C:N Ratio? • Provisions for static piles • SJV proposed rule concepts

  10. Staff Contacts • Jong Hoon Lee, Ph.D. – Rule Development Lead • Phone: (909) 396-3903 • Email: jhlee@aqmd.gov • Tracy Goss, P.E. – Program Supervisor • Phone: (909) 396-3106 • Email: tgoss@aqmd.gov • Jill Whynot – Director, Strategic Initiatives • Phone: (909) 396-3104 • Email: jwhynot@aqmd.gov
