E. 40 C.F.R. § 60 Appendix A-3 Method 4, incorporated in § 35.4(A) of this Part, shall be used to measure the moisture content of stack gas when required.

F. 40 C.F.R. § 60 Appendix A Methods 2, 2A, 2C, 2D, 3, and 4, incorporated in § 35.4(A) of this Part shall be performed, as applicable, at least twice during each test run.

G. VOC and VHAP control systems must be constructed so that volumetric flow rates and VOC and/or total VHAP concentrations, as applicable, can be determined by the test methods specified in §§ 35.12.3(A) through (F) of this Part, as applicable.

H. Capture efficiency shall be measured using measures approved by the EPA.

I. Testing shall be performed while all affected emission points are connected and operating at maximum production rate.

J. The efficiency § 35.12.3(F) of this Part of the control device shall be determined using Equation 7 in § 35.12.3(J) of this Part:

K. Determine the efficiency (N) of the capture system using Equation 8 in § 35.12.3(K) of this Part:

L. If all effected emissions points are surrounded by a permanent enclosure that is demonstrated to be total by procedures acceptable to the Department and the EPA, the control device capture efficiency, N, is equal to 1.
