NR 463.25(3)(e)(e) Volatile organic HAP emissions from automated pallet cooling lines or automated shakeout lines. To determine compliance with the VOHAP emissions limit in s. NR 463.23 (1) (a) 10. for automated pallet cooling lines or automated shakeout lines you shall use either the procedures in subds. 1. and 3. or subds. 2. and 3. NR 463.25(3)(e)1.1. To demonstrate compliance by direct measurement of total hydrocarbons, a surrogate for VOHAP, use all of the following procedures: NR 463.25(3)(e)1.a.a. Using the VOC CEMS required in s. NR 463.26 (1) (g), measure and record the concentration of total hydrocarbons, as hexane, for 180 continuous operating minutes. You shall measure emissions at the outlet of the control device, or at the outlet of the emissions source if no control device is present, prior to any releases to the atmosphere. NR 463.25(3)(e)2.2. To demonstrate compliance by establishing a site-specific TOC emissions limit that is correlated to the VOHAP emissions limit, use the following procedures: NR 463.25(3)(e)2.a.a. Determine the VOHAP concentration for each test run according to the test methods in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 484.04 (13), that are specified in this subdivision. 1) Method 1 or 1A to select sampling port locations and the number of traverse points in each stack or duct. Sampling sites shall be located at the outlet of the control device, or at the outlet of the emissions source if no control device is present, prior to any releases to the atmosphere.
2) Method 2, 2A, 2C, 2D, 2F or 2G to determine the volumetric flow rate of the stack gas.
3) Method 3, 3A or 3B to determine the dry molecular weight of the stack gas.
4) Method 4 to determine the moisture content of the stack gas.
5) Method 18 to determine the VOHAP concentration. Alternatively, you may use Method 25 to determine the concentration of TGNMO using hexane as the calibration gas.
NR 463.25(3)(e)2.b.b. Using the CEMS required in s. NR 463.26 (1) (g), measure and record the concentration of total hydrocarbons, as hexane, during each of the Method 18 or Method 25 sampling runs. You shall measure emissions at the outlet of the control device, or at the outlet of the emissions source if no control device is present, prior to any releases to the atmosphere. NR 463.25(3)(e)2.c.c. Calculate the average VOHAP or TGNMO concentration for the source test as the arithmetic average of the concentrations measured for the individual test runs and determine the average concentration of total hydrocarbon, as hexane, as measured by the CEMS during all test runs. where:
CVOHAP,avg is the average concentration of VOHAP for the source test in ppmv as measured by Method 18 in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 484.04 (16), or the average concentration of TGNMO for the source test in ppmv as hexane as measured by Method 25 in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 484.04 (19) CCEM is the average concentration of total hydrocarbons in ppmv as hexane as measured using the CEMS during the source test
NR 463.25(3)(e)3.3. For 2 or more exhaust streams from one or more automated conveyor and pallet cooling lines or automated shakeout lines, compute the flow-weighted average concentration of VOHAP emissions for each combination of exhaust streams using Equation 3: where:
CW is the flow-weighted concentration of VOHAP or VOC, ppmv, as hexane
Ci is the concentration of VOHAP or VOC from exhaust stream i, ppmv, as hexane
n is the number of exhaust streams sampled
Qi is the volumetric flow rate of effluent gas from exhaust stream i in dscfm
NR 463.25(3)(f)(f) Triethylamine emissions. To determine compliance with the emissions limit or standard in s. NR 463.23 (1) (a) 11. for a TEA cold box mold or core making line, you shall use the following test methods and procedures: NR 463.25(3)(f)1.a.a. Method 1 or 1A to select sampling port locations and the number of traverse points in each stack or duct. If you elect to meet the 99% reduction standard, sampling sites shall be located both at the inlet to the control device and at the outlet of the control device prior to any releases to the atmosphere. If you elect to meet the concentration limit, the sampling site shall be located at the outlet of the control device, or at the outlet of the emissions source if no control device is present, prior to any releases to the atmosphere.
