I. GENERAL INFORMATION

District: San Joaquin Valley Unified Air Pollution Control District

Rule No(s): 4566 Date adopted/Amended/Rescinded: Adopted August 18,2011.

Rule Title(s): Rule 4566 (Organic Material Compost ing Operations)

Date Submitted to ARB: September 13, 2011

If an Amended Rule, Date Last Amended (or Adopted): N/A

Narrative Summary of New Rule or Rule Changes: New Rule Amended Rule

Consistent with the 2007 Ozone Plan commitments, Ru le 4566 would establish VOC limits, including opera tional and administrative requirements, for composting ope rations, specifically the process of composting and /or stockpiling of organic materials subject to this ru le. The requirements are based on best available s cience and information collected through collaborative efforts of the composting community. The rule would requi re operators to reduce VOC emissions through feasible and cost-e ffective mitigation measures based on the organic m aterial receiving throughput category for the composting op eration. The rule would provide an extended compli ance schedule for facilities subject to more stringent c omposting requirements, such as the finished compos t cover or engineered control systems, to minimize the rule im pacts to those facilities. The emissions reduction percentage

that the District would achieve from this rule is s ignificantly higher than the 2007 Ozone Plan estima tes for this

source category.

Baseline Inventory in the SIP for the Control Measu re: 57 tons VOC per day in 2012

Emissions Reduction Commitment in the SIP for the C ontrol Measure: 9 tons VOC per day by 2012 (or 16% reduction)

Revised Baseline Inventory (if any): 13.9 tons per day

Revised Emission Reduction Estimate (if developed): 3.5 tons per day by 2012 (or 25% reduction) and 4 .2 tons per day by full implementation in 2016 (or 30% reduction)

Note that the district’s input to the Rule Evaluati on Form will not be used as input to the ARB’s emis sion forecasting and planning.

VI. IMPACT ON AIR QUALITY PLAN

No Impact Impacts RFP Impacts attainment

Discussion: The adoption of Rule 4566 is part of a control measure in the District's 2007 Ozone Plan. This measure, in conjunction with the other control measures in this plan, would help the District attain the federal 8 -hour ozone standard. Rule 4566 is expected to help achieve significant e missions reduction by reducing 30% of VOC emissions from the
estimated baseline, which is more than the reductio ns originally estimated in the 2007 Ozone Plan for this source category.
