where:
P is the asphalt charging rate to blowing still, Mg/hr (ton/hr)
V is the volume of asphalt charged, m3 (ft3)
d is the density of asphalt, kg/m3 (lb/ft3)
K’ is the conversion factor, 1000 kg/Mg (2000 lb/ton)

K1 is 1056.1 kg/m3 for metric units and 64.70 lb/ft3 for English units
K2 is 0.6176 kg/(m3 °C) for metric units and 0.0694 lb/(ft3 °F) for English units
Ti is the temperature at the start of the blow, °C (°F)
NR 440.59(5)(d)(d) The department shall determine compliance with the standards in sub. (3) (a) 3. by using Method 22, modified so that readings are recorded every 15 seconds for a period of consecutive observations during representative conditions, in accordance with s. NR 440.08 (3), totaling 60 minutes. A performance test shall consist of one run. NR 440.59(5)(e)(e) The owner or operator shall use the monitoring device in sub. (4) (a) or (b) to monitor and record continuously the temperature during the particulate matter run and shall report the results to the department with the performance test results. NR 440.59(5)(f)(f) If at a later date the owner or operator believes that the emission limits in sub. (3) (a) and (b) are being met even though one of the conditions in subd. 1. or 2. exists, the owner or operator may submit a written request to the department to repeat the performance test and procedure outlined in par. (c). NR 440.59(5)(f)1.1. The temperature measured in accordance with sub. (4) (a) is exceeding that measured during the performance test. NR 440.59(5)(f)2.2. The temperature measured in accordance with sub. (4) (b) is lower than that measured during the performance test. NR 440.59 NoteNote: Under 40 CFR 60.474 (g), if fuel oil is to be used to fire an afterburner used to control emissions from a blowing still, the owner or operator may petition the administrator in accordance with 40 CFR 60.11 (e), to establish an opacity standard for the blowing still that will be the opacity standard when fuel oil is used to fire the afterburner. To obtain this opacity standard, the owner or operator must request the administrator to determine opacity during an initial, or subsequent, performance test when fuel oil is used to fire the afterburner. Upon receipt of the results of the performance test, the administrator will made a finding concerning compliance with the mass standard for the blowing still. If the administrator finds that the facility was in compliance with the mass standard during the performance test but failed to meet the zero opacity standard, the administrator will establish and promulgate in the Federal Register an opacity standard for the blowing still that will be the opacity standard when fuel oil is used to fire the afterburner. When the afterburner is fired with natural gas, the zero percent opacity remains the applicable opacity standard. NR 440.59 HistoryHistory: Cr. Register, January, 1984, No. 337, eff. 2-1-84; am.
