History of Compost Emissions
• First SCAQMD Source testing in 2001
• Rule 1133 initially focused on biosolids emissions
• Similarly Rule 4566 (SJVAPCD) focused on biosolids and manure
• Now looking at green materials

Other approaches:
• Yolo-Solano AQMD and Sacramento Metropolitan AQMD using a “grandfather” approach:
• SWFP limit * Emission factor = VOC “cap”
• O.K. for existing facilities, unknown for new facilities.

Appropriate focus of 1133.3
• Regulate the process or the source?
• More green material in SCAQMD going to land ap. or ADC.
• ADC may be on the ground for up to 3 weeks prior to spreading.

Current Status of Rule 4566
• Committed group of composters sharing data.
• SJVAPCD committed to creating a rule which balances need for reductions with reality of composting industry.
• SJVAPCD has made a number of significant changes in response to industry comments.
• Existing Rule 2201 bigger concern

Mitigations
• Hired SDSU to study potential mitigation alternatives.
• Focusing on two:
– Irrigation (24% VOC Reduction)
– Compost Cap (53% VOC Reduction)
• Medium vs. Large Facilities
• Next Meeting December 9 (Fresno)

The Primary Concern
• Cost of compliance will affect already marginal economics of composting, sending organics needed for the soil to other, cheaper, less sustainable options.
• We need more facilities, not less, especially in Southern California.

Need to Organize
