Section 096-124-6 - Test Methods

A.For the purpose of determining compliance with Section 3 of this Chapter, the following EPA Reference Methods from Appendix A of 40 CFR Part 60 and Chapter 117 shall be used:

(1) Method 16 or, at the discretion of the owner or operator, Method 16A or, Method 16B as approved by the Department, for the concentration of TRS;

(2) Method 3 for gas analysis; and

(3) When determining compliance with Section 3(J) of this Chapter, the owner or operator of a system subject to this Chapter must use the results of Method 2, Method 16, Method 16A, Method 16B and the black liquor solids feed rate in the following equation to determine the TRS emission rate on an equivalent H₂S basis.

E=(C_TRS) (F) (Q_sd)/BLS

Where: E=mass of TRS emitted per unit of black liquor solids (g/kg) or (lb./ton).

C_TRS= average combined concentrations of TRS (ppm), as determined by Method 16, 16A or 16B during the test period.

F=0.001417 g H₂S/m³ ppm for metric units.

=0.08844 x 10^-6 lb. H₂S/ft³ppm for English units.

Q_sd= dry volumetric stack gas flow rate (dscm/hr or dscf/hr), corrected to standard conditions.

BLS= black liquor solids feed rate (kg/hr or ton/hr).

B. All concentrations of TRS required to be measured by this section from lime kilns, incinerators, or other combustion devices shall be corrected to ten (10)% oxygen by volume and those concentrations from recovery furnaces shall be corrected to eight (8)% oxygen by volume. These corrections shall be made in the manner specified in Section 5(A)(3) of this Chapter.

C. The Department and EPA may approve equivalent test methods.
