Section 211.1670  Daily-Weighted Average VOM Content

 

"Daily-weighted average VOM content" means the average VOM content of two or more coatings as applied on a coating line during any day, taking into account the fraction of total coating volume that each coating represents, as calculated with the following equation:

 

 

 

[

n

 

]

 

VOMw

=

Σ

Vi   Ci

/ VT

 

 

i=1

 

 

 

where:

 

VOMw

=

The average VOM content of two or more coatings as applied each day on a coating line in units of kg VOM/l (lbs VOM/gal) of coating (minus water and any compounds which are specifically exempted from the definition of VOM),

 

n

=

The number of different coatings as applied each day on a coating line,

 

Vi

=

The volume of each coating (minus water and any compounds which are specifically exempted from the definition of VOM) as applied each day on a coating line in units of 1 (gal).

 

Ci

=

The VOM content of each coating as applied each day on a coating line in units of kg VOM/1 (lbs VOM/gal) of coating (minus water and any compounds which are specifically exempted from the definition of VOM), and

 

VT

=

The total volume of all coatings (minus water and any compounds which are specifically exempted from the definition of VOM ) as applied each day on a coating line in units of 1 (gal).
