# Tenn. Comp. R. & Regs. 1200-03-18-.82 - TEST METHODS AND COMPLIANCE PROCEDURES: ALTERNATIVE COMPLIANCE METHODS FOR SURFACE COATING

(1) The weighted average VOC content, in units of mass of VOC per volume of coating and/or ink, excluding water and/or exempt compounds, as applied, of the coatings and/or inks used on a day on a coating line or operation shall be calculated using the following equation:

where:

VOCw = The weighted average VOC content of the coatings and/or inks, as applied, used on a line or operation in units of kilograms of VOC per liter of coating and/or ink (kg VOC/L) (pounds of VOC per gallon of coating and/or ink [lb VOC/gal]), excluding water and/or exempt compounds;

n = The number of different coatings and/or inks, as applied, each day on a line or operation;

Vi = The volume of each coating or ink, as applied, each day on a line or operation in units of L (gal), excluding water and/or exempt compounds; and

Ci = The VOC content of each coating or ink, as applied, each day on a line or operation in units of kg VOC/L of coating or ink (lb VOC/gal), excluding water and/or exempt compounds; and

VT = The total volume of all coating and/or ink, as applied, each day on a line or operation in units of L (gal), excluding water and/or exempt compounds.

(2) [Reserved]
(3) The overall emission reduction efficiency needed to demonstrate compliance is determined each day as follows:
(a) Obtain the emission limitation from the applicable rule of this chapter.
(b) Calculate the emission limitation on a solids basis according to the following equation:

where:

S = The VOC emission limitation in terms of kg VOC/L of coating or ink solids (lb VOC/gal);

C = The VOC emissions limitation in terms of kg VOC/L of coating or ink (lb/gal), excluding water and/or exempt compounds; and d = The density of VOC for converting emission limitation to a solids basis. The density equals 0.882 kg/L (7.36 lb/gal).

(c) Calculate the required overall emission reduction efficiency of the control system for the day according to the following equation:

where:

E = The required overall emission reduction efficiency of the control system;

VOCa = 1. The maximum VOC content of the coatings and/or inks, as applied, used each day on the subject line or operation, in units of kg VOC/L of solids (lb/gal), as determined by the applicable test methods and procedures specified in this chapter; or 2. The weighted average VOC content, as applied, of the coatings and/or inks used each day on the subject line or operation, in units of kg VOC/L of solids (lb/gal), as determined by the applicable test methods and procedures specified in this chapter and the procedure in Subparagraph (d) of this paragraph; and

S = VOC emission limitation in terms of kg VOC/L of solids (lb VOC/gal).

(d) The weighted average VOC content, as applied, of the coatings and/or inks used on a coating line or operation in units of mass of VOC per unit volume of coating and/or ink solids shall be calculated by the following equation:

where:

VOCws = The weighted average VOC content, as applied, of the coatings and/or inks used on the line or operation in units of mass of VOC per unit volume of coating and/or ink solids;

n = The number of different coatings and/or inks, as applied, used in a day on the line or operation;

Vi = The volume of each coating or ink (i), as applied, used in a day on the line or operation in units of liters (L) (gallons[gal]);

Wvoci = The weight fraction of VOC in each coating or ink (i), as applied, used in a day on the line or operation in units of kg VOC/kg coating or ink (lb/lb);

Di = The density of each coating or ink (i) as applied, used in a day on the line or operation in units of kg/L of coating or ink (lb/gal);

VSi = The volume fraction solids content of each coating or ink (i), as applied, used in a day on the line or operation in units of L solids/L coating or ink (gal/gal).
