Presentation Transcript
existing air quality
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
purpose
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
schedule and process
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
universe of sources
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

emissions
Emissions
  • VOCs:
    • 1,330 tons/year (3.6 tons/day)
  • NH3:
    • 300 tons/year (0.8 tons/day)
basic concepts
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
key input received
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
concepts under consideration
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
