405 CALCULATION FOR DETERMINING PERCENT CONTROL EFFICIENCY AND VOC
MASS EMISSION RATE: The VOC mass emission rate shall be calculated both upstream and downstream of the emissions control device based on the respective VOC mass concentration and volumetric flowrate, pursuant to Section 502.4 and t he following equation: 

# ( ) ( ) ( ) hr C Q M min/ 60 =

Where: M = VOC mass emission rate, in lb/hr. Q = the volumetric flowrate of the exhaust stack, in scfm. C = the VOC mass concentration, in lb/scf, as measured by
EPA Method 25.

The percent control efficiency is calculated as follows:



### %CE = [ (M U 

### – M D 

### ) / M U 

### ] X 100

M U = the upstream VOC mass emission rate, in lb/hr.
M D = the downstream VOC mass emission rate, in lb/hr.

406 CALCULATION FOR DETERMINING OVERALL SYSTEM EFFICIENCY: The overall system efficiency is calculated as follows:
