S = C / [1 - (C/7.36 lb/gal)]
Where:
S = The volatile organic compound emission limitation in terms of pound of volatile organic compound per gallon of coating solids.
C = The volatile organic compound emission limitation in terms of pound of volatile organic compound per gallon of coating, (excluding water) as applied.
E = [(VOCa - S)/VOCa] x 100
Where:
E = The required overall emission reduction efficiency of the control system for the day.
VOCa = The maximum VOC content of the coatings, as applied, used each day on the subject coating line, in units of lb VOC/gal coating solids, as determined by the applicable test methods and procedures specified in subdivision (h) of this subrule.
S = The volatile organic compound emission limitation in terms of pound of volatile organic compound per gallon of coating solids.
