par. (a) or
(b).
NR 469.08(1)(a)
(a) If the cleaning machine has a solvent/air interface, the owner or operator shall comply with both of the following requirements:

1. Maintain a log of solvent additions and deletions for each solvent cleaning machine.
NR 469.08(1)(a)2.
2. Ensure that the emissions from each solvent cleaning machine are equal to or less than the applicable emission limit presented in Table 6 as determined using the procedures in
s. NR 469.09 (2) and
(3).
NR 469.08(1)(b)
(b) If the cleaning machine is a batch vapor cleaning machine and does not have a solvent/air interface, the owner or operator shall comply with all of the following requirements:
NR 469.08(1)(b)1.
1. Maintain a log of solvent additions and deletions for each solvent cleaning machine.
NR 469.08(1)(b)2.

b. For cleaning machines with a cleaning capacity, as reported in
s. NR 469.12 (4) (c), that is greater than 2.95 cubic meters (104 cubic feet), the emission limit shall be determined using equation 1.

469.077, each owner or operator of a continuous web cleaning machine may demonstrate an overall cleaning system control efficiency of 70% or greater using the procedures in
s. NR 469.09 (7). This demonstration may be made for either a single cleaning machine or for a solvent cleaning system that contains one or more cleaning machines and ancillary equipment, such as storage tanks and distillation units. If the demonstration is made for a cleaning system, the facility shall identify any modifications required to the procedures in
s. NR 469.09 (7) and they shall be approved by the department.
