VI. IMPACT ON AIR QUALITY PLAN

No Impact Impacts RFP Impacts attainment

Discussion: There are no changes to existing VOC l imits in the amendments to Rule 1124. The requirem ents are more

stringent as they align specialty coating categorie s to those in the CTG by adding definition and cate gories 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.
