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

The amendment of Rule 4570 will result in emission reductions from CAFs and utilization of new science on 

emissions. The regulatory threshold has been lowered to include medium dairies and poultry CAFs. Many of the 

tables have been revised and enhanced to specify mandated measures in high emission source categories such 

as feed, silage and housing, while still maintaining flexibility to accommodate the variability of individual operators 

and facilities. Control requirement tables have been strengthened and streamlined, requiring more mandatory 

measures that are feasible. Mitigation measures from all categories of CAFs, which were determined not to be as 

effective as other measures, or either not technologically feasible or cost effective, were removed from rule 

language.

Pollutant(s) Regulated by the Rule (Check): ROG (NOx) SO2 

 (CO) PM TAC (name):

Baseline Inventory in the SIP for the Control Measure: 55 tons/day in 2012, 67 tons/day in 2023 (summer season)

Emissions Reduction Commitment in the SIP for the Control Measure: 6.7 tons/day in 2012, 22.9 tons/day in 2023 

(summer season) 

Revised Baseline Inventory (if any): 122.4 tons/day in 2012, 154 tons/day in 2023 

Revised Emission Reduction Estimate (if developed): 25.2 tons/day in 2012, 31.8 tons/day in 2023 

Note that the district’s input to the Rule Evaluation Form will not be used as input to the ARB’s emission forecasting and 

planning.

VI. IMPACT ON AIR QUALITY PLAN

 No Impact Impacts RFP Impacts attainment 

Discussion: While no single rule will achieve attainment for the Valley, the adoption of Rule 4570 satisfies control 

measure commitments in the 2007 Ozone Plan, adopted on April 30, 2007, and will achieve even more reductions than 

committed to in the SIP.
