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

Amendments to Rule 4307 require that tree nut pasteurizers be fired on natural gas as a NOx control. This 

strategy is similar to the requirements imposed on vegetable dehydrators in District Rule 4309, a rule that has 

been approved by EPA into the California State Implementation Plan (SIP). During natural gas curtailments, units 

would either not be used or would have to meet the requirements of Section 4.6. Section 4.6 outlines limitations 

for a unit that fires on alternative fuels during natural gas curtailments. Since the pasteurizer is already operating, 

the requirement took effect on the date of rule adoption; therefore, no commencement date was needed for this 

provision. 

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

VI. IMPACT ON AIR QUALITY PLAN 

 No Impact Impacts RFP Impacts attainment 

Discussion: This rule project is not a control measure in any attainment plan and is not expected to reduce or increase 

emissions from the single existing tree nut pasteurizer. For these reasons, the District has concluded that attainment of 

any ambient air quality standard will not be affected by this rule project. The amendments will not affect the District’s 2007 

Ozone Plan or the District's 2008 PM2.5 Plan because no emission limits have been changed, nor are the amendments 

expected to affect emissions from this source category.
