Proposed rule 1133 3 emission reductions from greenwaste composting operations

UPDATE

Proposed Rule 1133.3 – Emission Reductions from Greenwaste Composting Operations

December 2, 2010


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
