When an absorber is the final unit in a system to demonstrate compliance with sub. (3) except sub. (3) (a) 2., the specific gravity, or alternative parameter that is a measure of the degree of absorbing liquid saturation, if approved by the department, and average temperature, measured at least every 15 minutes and averaged over the performance test period, of the absorbing liquid, both measured while the vent stream is normally routed and constituted. NR 440.647(7)(a)7.7. When a condenser is the final unit in a system to demonstrate compliance with sub. (3) except sub.

(3) (c) 1. b. 2) or 2. b. 2) or of the ethylene glycol concentration in the cooling water in the cooling tower, if subject to sub. (3) (c) 2. b. 3) or c. 3). NR 440.647(7)(a)9.9. When a carbon adsorber is the final unit in a system to demonstrate compliance with sub. (3) except sub. (3) (a) 2., the concentration level or reading indicated by the organics monitoring device at the outlet of the adsorber, measured at least every 15 minutes and averaged over the performance test period while the vent stream is normally routed and constituted.

(1) (d) and (e) or with the individual stream exemptions in sub. (1) (g), each process operation variable, for example, pressure, temperature, type of catalyst, that may result in an increase in the uncontrolled emission rate, if sub. (1) (d) or (e) is applicable or in an increase in the uncontrolled annual emissions or the VOC weight percent, as appropriate, if sub. (1) (g) is applicable, should such operating variable be changed. NR 440.647(7)(a)11.11. When an owner or operator uses a control device to comply with sub. (3) (a) 1. a. 4) alone: all periods when the control device is not operating. NR 440.647(7)(b)1.1. Each owner or operator subject to the provisions of this section shall submit with the initial performance test or, if complying with sub. (3) (a) 1. a. 4) as a separate report, an engineering report describing in detail the vent system used to vent each affected vent stream to a control device. This report shall include all valves and vent pipes that could vent the stream to the atmosphere, thereby bypassing the control device and identify which valves are car-sealed opened and which valves are car-sealed closed. NR 440.647(7)(b)2.2.
