Test methods

Test methods. (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 . (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. (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) . (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 (E i or E n ) using equation 2 for cleaning machines with a solvent/air interface and equation 3 for cleaning machines without a solvent/air interface. (b) Determine SSR i using the method specified in subd. 1. or 2. 1. From tests conducted using Method 25D in Appendix A of 40 CFR part 60 , incorporated by reference in s. NR 484.04 . 2. By engineering calculations included in the compliance report, which is described in s. NR 469.12 (6) . (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. (4) Each owner or operator of a batch vapor or in-line solvent cleaning machine using dwell to comply with ss. NR 469.04 to 469.07 shall determine the appropriate dwell time for each part or parts basket using the procedure specified in pars. (a) and (b) . (a) Determine the amount of time for the part or parts basket to cease dripping once placed in the vapor zone. The part or parts basket used for this determination shall be at room temperature before being placed in the vapor zone. (b) The proper dwell time for parts to remain in the freeboard area above the vapor zone is no less than 35% of the time determined in par. (a) . (5) An owner or operator of a source shall determine the source’s potential to emit from all solvent cleaning machines, using the procedures described in pars. (a) to (c) . (a) Determine the potential to emit for each individual solvent cleaning machine using equation 6. (b) Solvent cleaning machines that do not have a solvent/air interface shall calculate a solvent/air interface area using equation 7. (c) Sum the PTE i for all solvent cleaning machines to obtain the total potential to emit for solvent cleaning machines at the facility. (6) Each owner or operator of a continuous web cleaning machine using a squeegee system to comply with s. NR 469.073 (3) shall determine the maximum product throughput using the method in this subsection. The maximum product throughput for each squeegee type used at a facility shall be determined prior to December 2, 1999, the compliance date for these units. (a) Conduct daily visual inspections of the continuous web part. This monitoring shall be conducted at the point where the continuous web part exits the squeegee system. It is not necessary for the squeegees to be new at the time monitoring is begun if the following 2 conditions are met: 1. The continuous web part leaving the squeegee system has no visible solvent film. 2. The amount of continuous web that has been processed through the squeegees since the last replacement is known. (b) Continue daily monitoring until a visible solvent film is noted on the continuous web part. (c) Determine the length of continuous web product that has been cleaned using the squeegee since it was installed. (d) The maximum product throughput for the purposes of this chapter is equal to the time it takes to clean 95% of the length of product determined in par. (c) . This time period, in days, may vary depending on the amount of continuous web product cleaned each day. (7) Each owner or operator of a continuous web cleaning machine demonstrating compliance with the alternative standard of s. NR 469.08 (4) shall, on the first day of every month, ensure that the solvent cleaning machine contains only clean liquid solvent. A fill-line shall be indicated during the first month the measurements are made. The solvent level with the machine shall be returned to the same fill-line each month, immediately prior to calculating overall cleaning system control efficiency emissions as specified in sub. (8) . The solvent cleaning machine does not need to be emptied and filled with fresh unused solvent prior to the calculation. (8) Each owner or operator of a continuous web cleaning machine complying with s. NR 469.08 (4) shall, on the first operating day of the month, determine the overall cleaning system control efficiency (E o ) for the previous month using equation 8 and the records of all solvent additions, solvent deletions and solvent recovered from the carbon adsorption system for the previous monthly reporting period required under s. NR 469.11 (5) .
