NR 465.27(2)(e)2. 2. If you choose to account for the mass of organic HAP contained in waste materials sent or designated for shipment to a hazardous waste TSDF in the calculation of the mass of organic HAP emissions using Equation 1, you shall determine it according to the following procedures:

NR 465.27(2)(e)2.a. a. You may include in the determination of organic HAP in waste materials only the waste materials that are generated by coating operations for which you use Equation 1 in subd. 1. and that will be treated or disposed of by a facility that is regulated as a TSDF under 40 CFR part 262, 264, 265, or 266. The TSDF may be either off-site or on-site. You may not include in the determination the organic HAP contained in wastewater.

NR 465.27(2)(e)2.b. b. Determine either the amount of waste materials sent to a TSDF during the compliance period or the amount collected and stored during the compliance period and designated for future transport to a TSDF. You may not include in your determination any waste materials sent to a TSDF during a compliance period if you have already included them in the amount collected and stored during that compliance period or a previous compliance period.

NR 465.27(2)(e)2.c. c. Determine the total mass of organic HAP contained in the waste materials specified in subd. 2. b.

NR 465.27(2)(e)2.d. d. Document your methodology to determine the amount of waste materials and the total mass of organic HAP they contain, as required in s. NR 465.25 (3) (h).

NR 465.27(2)(e)2.e. e. To the extent that waste manifests include this information, they may be used as part of the documentation of the amount of waste materials and mass of organic HAP contained in them.

NR 465.27(2)(f) (f) Determine the total volume of coating solids used, liters, which is the combined volume of coating solids for all of the coatings used during the compliance period, using the following equation:

  Vst is the total volume of coating solids used during the compliance period, liters

  Volc,i is the total volume of coating, i, used during the compliance period, liters

  Vs,i is the volume fraction of coating solids for coating, i, liters solids per liter coating, determined according to s. NR 465.26 (2) (b)

  m is the number of coatings used during the compliance period
