cleaning requirem ents by replace the vapor pressure limits with the ultra

- low ROC content limit of 25 grams per liter

. The revision to Rule 74.13 will

instead lower the partial ROC vapor pressure limit requirement for spray gun cleaning from 45 to 5 mm Hg.

II. EFFECT ON EMISSIONS

Complete this section ONLY for rules that, when implemented, will result in quantifiable changes in emission. Attach referen ce(s) for emission factor(s) and other

infor mation. Attach calculation sheet showing how the emissions information provided below was determined. See staff report Appen dix A for emission calculations.

Net Effect on Emissions: ( ) Increase ( X ) Decrease ( ) N/A No impact on emissions. See attache d staff report for emission reduction

calculations. The net effect of the three rules is to reduce ROC emissions by 9 tons per year.

II. EFFECT ON EMISSIONS
