VI. IMPACT ON AIR QUALITY PLAN

 No Impact Impacts RFP Impacts attainment 

Discussion: There is no reduction in current emissions baseline resulting from the amendments to Rule 4603 since 

sources in the San Joaquin Valley Air Basin are already using coatings that comply with the new VOC limits. There is no 

reduction in current emissions baseline resulting from the amendments to Rule 4684 sources are using materials that 

meet the standards. These rule amendments, however, are necessary to satisfy federal RACT and CTG requirements.
