VI. IMPACT ON AIR QUALITY PLAN 

 No Impact Impacts RFP Impacts attainment 

Discussion: There are no changes to existing VOC limits in the amendments to Rule 1124. The requirements are more 

stringent as they align specialty coating categories to those in the CTG by adding definition and categories previously not 

covered. There is no potential that the amendments to Rule 1124 will cause the release of additional air contaminants or 

create any environmental impacts.
