VOCB = (Wo)/(Wn)
Where:
VOCB = VOC content in lb VOC/lb of solids as applied or kg VOC/kg of solids as applied
Wo = Weight percent of VOC (Wv-Ww-Wex)
Wv = Weight percent of total volatiles (100%-weight percent solids)
Ww = Weight percent of water
Wex = Weight percent of exempt solvents
Wn = Weight percent of solids of the as applied ink, coating or adhesive
Where:
VOCw=The daily weighted average VOC content, as applied, of all inks, coatings and adhesives combined used on a single flexible packaging printing press, in lb VOC/gal of coating solids
n=The number of different inks, coatings and adhesives used each day on the single flexible packaging printing press
Vi=The volume of solids for each ink, coating and adhesive, as applied, used each day on the single flexible packaging printing press, in gallons
Ci=The VOC content of each ink, coating and adhesive, as applied, used each day on the single flexible packaging printing press, in lb VOC/gal coating solids
Vt=The total volume of solids for all inks, coatings and adhesives combined, as applied, used each day on the single flexible packaging printing press, in gallons

1 First installation date is the first date of operation for a source or a control device. This date does not change if the source or control device is moved to a new location or if the control device is later used to control a new source.
* March 14, 1995, is the date of the proposed 1996 NESHAP for the printing and publishing industry.
** January 1, 2015, is the compliance date of the flexible packaging printing press regulation.
