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:

VOMw |
= |

/ 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). |
