NR 440.644(4)(f)2.d.d. The owner or operator of an affected facility may substitute the following procedure as an acceptable alternative to the requirements prescribed under par. (f) 2. a. This alternative procedure is acceptable only in cases where a single VOC is used and is present in the capture system. The average capture efficiency value derived from a minimum of 3 runs shall constitute a test. 1) For each run, ‘‘i”, measure the mass of the material containing a single VOC used. This measurement shall be made using a scale that has both a calibration and a readability to within 1% of the mass used during the fun. This measurement may be made by filling the direct supply reservoir, for example, rollers, pumps, hoses, to a marked level at the start of the run and then refilling to the same mark from a more easily weighed container, for example, a separate supply drum, at the end of the fun. The change in mass of the supply drum would equal the mass of the material used in the run. If only the direct supply reservoir is weighed, the amount of material in or on the related application equipment shall be the same at the start and end of the run. All additions of VOC containing material shall be properly accounted for in determining the mass of material used during that run.
2) For each run, “i”, measure the mass of the material containing a single VOC which is present in the direct supply reservoir and related application equipment at the start of the run, unless the ending weight fraction VOC in the material is greater than or equal to 98.5% of the starting weight fraction VOC in the material, in which case, this measurement is not required. This measurement may be made directly by emptying the direct supply reservoir and related application equipment and then filling them to a marked level from an easily weighed container, for example, a separate supply drum. The change in mass of the supply drum would equal the mass of material in the filled direct supply reservoir and related application equipment. Alternatively, this measurement may be made by weighing the direct supply reservoir and related application equipment at the start of the run and subtracting the mass of the empty direct supply reservoir and related application equipment (tare weight).
3) For each run, “i”, the starting weight fraction VOC in the material shall be determined by Method 24 analysis of a sample taken from the direct supply reservoir at the beginning of the run.
4) For each run, “i”, the ending weight fraction VOC in the material shall be determined by Method 24 analysis of a sample taken from the direct supply reservoir at the end of the run.
5) For each run, “i”, in which the ending weight fraction VOC in the material is greater than or equal to 98.5% of the starting weight fraction VOC in the material, calculate the mass of the single VOC used (Mi) by multiplying the mass of the material used in the run by the starting weight fraction VOC of the material used in the run.
6) For each run, “i”, in which the ending weight fraction VOC in the material is less than 98.5% of the starting weight fraction VOC in the material, calculate the mass of the single VOC used (Mi) as follows:
a) Calculate the mass of VOC present in the direct supply reservoir and related application equipment at the start of the run by multiplying the mass of material in the direct supply reservoir and related application equipment at the start of the run by the starting weight fraction VOC in the material for that run.
b) Calculate the mass of VOC present in the direct supply reservoir and related application equipment at the end of the run by multiplying the mass of material in the direct supply reservoir and related application equipment at the end of the run by the ending weight fraction VOC in the material for that run. The mass of material in the direct supply reservoir and related application equipment at the end of the run shall be calculated by subtracting the mass of material used in the run from the mass of material in the direct supply reservoir and related application equipment at the start of the run.
c) The mass of the single VOC used (Mi) equals the mass of VOC present in the direct supply reservoir and related application equipment at the start of the run minus the mass of VOC present in the direct supply reservoir and related application equipment at the end of the run.
7) If Method 25A is used to determine the concentration of the single VOC in the capture system, then calculate the capture efficiency (FCi) for each run, “i”, as follows: where:
Ci is the average concentration of the single VOC in the capture system during run “i” (parts per million by volume) corrected for background VOC
NR 440.644 NoteNote: See sub. (8) (a) 5.
W is the molecular weight of the single VOC, mg/mg-mole (lb/lb-mole)
V is the volume occupied by one mole of ideal gas at standard conditions (20°C, 760 mm Hg) on a wet basis, 2.405 x 10-5 m3/mg-mole (385.3 ft3/lb-mole)
Qi is the volumetric flow in in the capture system during run “i”, on a wet basis, adjusted to standard conditions , m3 (ft3)
NR 440.644 NoteNote: See sub. (8) (a) 5.
106 is the ppm per unity
Mi is the mass of the single VOC used during run “i”, mg (lb)
8) If Method 25 is used to determine the concentration of the single VOC in the capture system, then calculate the capture efficiency (FCi) for each run, “i”, as follows: where:
Ci is the average concentration of the single VOC in the capture system during run “i” (parts per million, as carbon, by volume) corrected for background VOC
NR 440.644 NoteNote: See sub. (8) (a) 5.
W is the molecular weight of the single VOC, mg/mg-mole (lb/lb-mole)
V is the volume occupied by one mole of ideal gas at standard conditions (20°C, 760 mm Hg) on a wet basis, 2.405 x 10-5 m3/mg-mole (385.3 ft3/lb-mole)
