 VOC e mission f actor for w estern h emlock with k iln f iring t emperature ≤ 200° F, as shown in Condition

41 : 0.5253 lb s /mbf

 VOC e missions (tons/ month ) = 1 mbf/ month *0.5253 lb s /mbf*(1 ton s /2

, 000 lbs)

 VOC e missions (tons/ month ) = 2 .3 01 tons/ month

Example 2: Coating Emissions

Methodology:

 VOC e missions (ton s /month) = s olvent usage (gallons)*density (lb s /gal)*% VOC*1 ton/2000 lbs

Sample:

 Assume: 5 gallons of coating used in a month, coating density of 5 lb s /gal lon , coating VOC content is

30%

 VOC e missions (ton s /month) = 5 gallons*5 lb s /gal lon *0. 30 VOC*1 ton/2000 lbs

 VOC e missions (ton s /month) = 0.00375 tons/monthGeneral Permit for Sawmill Facilities Page 16 of 16
