NR 469.09 NR 469.09 Test methods.

NR 469.09(1) (1) Except as provided in subs. (6) and (7) for continuous web cleaning machines, each owner or operator of a batch vapor or in-line solvent cleaning machine complying with an idling emission limit standard in s. NR 469.04 (2) (a) 2. or (b) 2. or (3) (a) 2. or (b) 2. shall determine the idling emission rate of the solvent cleaning machine using Method 307 in Appendix A of 40 CFR part 63, incorporated by reference in s. NR 484.04.

NR 469.09(2) (2) Except as provided in sub. (7) for continuous web cleaning machines, each owner or operator of a batch vapor or in-line solvent cleaning machine complying with s. NR 469.08 shall on the first operating day of every month ensure that the solvent cleaning machine system contains only clean liquid solvent as defined in s. NR 469.02 (5). A fill line shall be indicated during the first month the measurements are made. The solvent level within the machine shall be returned to the same fill line each month, immediately prior to calculating monthly emissions as specified in sub. (3). The solvent cleaning machine does not have to be emptied and filled with fresh unused solvent prior to the calculations.

NR 469.09(3) (3) Except as provided in subs. (6) and (7) for continuous web cleaning machines, each owner or operator of a batch vapor or in-line solvent cleaning machine complying with s. NR 469.08 (1) (a) or (b) shall on the first operating day of the month comply with the requirements specified in pars. (a) to (c).

NR 469.09(3)(a) (a) Using the records of all solvent additions and deletions for the previous monthly reporting period required under s. NR 469.08 (1) (a) 1. or (b) 1., determine solvent emissions (Ei or En) using equation 2 for cleaning machines with a solvent/air interface and equation 3 for cleaning machines without a solvent/air interface.

(Equation 2)

(Equation 3)

where:

Ei is the total halogenated HAP solvent emissions from the solvent cleaning machine during the most recent monthly reporting period i, kilograms of solvent per square meter of solvent/air interface area per month (pounds of solvent per square foot of solvent/air interface area per month)

En is the total halogenated HAP solvent emissions from the solvent cleaning machine during the most recent monthly reporting period i, kilograms of solvent per month (pounds of solvent per month)

SAi is the total amount of halogenated HAP liquid solvent added to the solvent cleaning machine during the most recent monthly reporting period i, kilograms of solvent per month (pounds of solvent per month)

LSRi is the total amount of halogenated HAP liquid solvent removed from the solvent cleaning machine during the most recent monthly reporting period i, kilograms of solvent per month (pounds of solvent per month)

SSRi is the total amount of halogenated HAP solvent removed from the solvent cleaning machine in solid waste, obtained as described in par. (b), during the most recent monthly reporting period i, kilograms of solvent per month (pounds of solvent per month)

AREAi is the solvent/air interface area of the solvent cleaning machine, square meters, (square feet)

NR 469.09(3)(b) (b) Determine SSRi using the method specified in subd. 1. or 2.

NR 469.09(3)(b)1. 1. From tests conducted using Method 25D in Appendix A of 40 CFR part 60, incorporated by reference in s. NR 484.04.

NR 469.09(3)(b)2. 2. By engineering calculations included in the compliance report, which is described in s. NR 469.12 (6).

NR 469.09(3)(c) (c) Determine the monthly rolling average, EA, for the 3-month period ending with the most recent reporting period using equation 4 for cleaning machines with a solvent/air interface or equation 5 for cleaning machines without a solvent/air interface.

(Equation 4)

(Equation 5)

where:

EAi is the average halogenated HAP solvent emissions over the preceding 3 monthly reporting periods, kilograms of solvent per square meter of solvent/air interface area per month (pounds of solvent per square foot of solvent/air interface area per month)

EAn is the average halogenated HAP solvent emissions over the preceding 3 monthly reporting periods, kilograms of solvent per month (pounds of solvent per month)
