VI. IMPACT ON AIR QUALITY PLAN

 No Impact Impacts RFP Impacts attainment 

Discussion: Rule 4612 is intended to reduce VOC emissions from motor vehicle and mobile equipment coating operations

by specifying material VOC content limits or emission control requirements. The amendments do not affect the meaning, 

scope, or prohibitions required of this source category and contained in rule language. As such, no emission reductions 

resulted from this action.
