(2m) INDUSTRIAL CLEANING OPERATIONS.
(a)
Solvent and solvent solution requirements. Except as provided
under par. (d), no owner or operator of a facility may cause, allow or permit
the use of a solvent or solvent solution for industrial cleaning operations
unless the VOC content of the solvent or solvent solution is less than or equal
to the applicable VOC content listed in Table 5 for the respective cleaning
operation. For the purposes of this subsection, VOC content shall be defined as
in s.
NR 423.02(11r).
Table 5
VOC Content Limits for Solvents and Solvent Solutions Used in Industrial Cleaning Operations

Cleaning Activity |
VOC Content of Solvent or Solvent Solution in kilograms per liter (pounds per gallon) |
|
1. Product cleaning or surface preparation during manufacturing process |
0.05 (0.42) |
|
2. Repair cleaning or maintenance cleaning |
0.50 (4.2) |
|
3. Cleaning of ink application equipment |
0.50 (4.2) |
(b)
Cleaning devices and methods requirements. Except as provided
under par. (d), the owner or operator of a facility shall comply with the
following requirements associated with the identified cleaning devices or
methods when using solvents or solvent solutions:
1. Physically rub a surface with a porous
applicator such as a rag, paper, sponge, or a cotton swab moistened with
solvent or solvent solution.
2.
Closed containers or hand held spray bottles from which solvents or solvent
solutions are applied without a propellant-induced force.
3. Cleaning equipment which has a solvent or
solvent solution container that is closed during cleaning operations, except
when depositing and removing objects to be cleaned, and is closed during
non-operation with the exception of maintenance and repair to the cleaning
equipment itself.
4. A remote
reservoir cleaner operated in compliance with all of the following
requirements:
a. Solvent vapors are prevented
from escaping from the solvent or solvent solution container by using devices
such as a cover or a valve when the remote reservoir is not being used,
cleaned, or repaired.
b. Flow is
directed in a manner that prevents solvent or solvent solution from splashing
outside of the remote reservoir cleaner.
c. The cleaner is not used for cleaning
porous or absorbent materials, such as cloth, leather, wood, or rope.
d. Only solvent or solvent solution
containers free of all liquid leaks are used. Auxiliary equipment, such as
pumps, pipelines, or flanges, may not have any liquid leaks, visible tears, or
cracks. Any liquid leak, visible tear, or crack detected shall be repaired
within one calendar day, or the leaking section of the remote reservoir cleaner
shall be drained of all solvents or solvent solutions and shut down until it is
replaced or repaired.
5.
A non-atomized flow method where the used solvents or solvent solutions are
collected in a container or a collection system which is closed, except for the
solvent or solvent solution collection openings that may be open when filling
or emptying, or the opening caused by use of a pressure relief valve.
6. A flushing method where the used solvents
or solvent solutions are discharged into a container which is closed, except
for the solvent or solvent solution collection openings that may be open when
filling or emptying, or the opening caused by use of a pressure relief valve.
The discharged solvents or solvent solutions shall be collected into containers
without atomizing into the open air.
(c)
Storage and disposal.
The owner or operator of a facility shall store all solvents or solvent
solutions used in industrial cleaning operations in non-absorbent, non-leaking
containers which shall be kept covered except when filling or emptying. Cloth
and paper moistened with solvents or solvent solutions shall be stored in
covered, non-absorbent, non-leaking containers.
(d)
Control equipment. In
lieu of complying with the requirements in pars. (a) and (b), the owner or
operator of a facility may use a VOC emission control system to control VOC
emissions from the industrial cleaning operations at the facility provided one
of the following requirements is met:
1. The
emission control system has a minimum overall emission reduction efficiency of
85% for VOC emissions, as determined in accordance with s.
NR 439.06(3) (am).
2. The emission control system has a minimum
VOC capture efficiency of 90% and an output of VOC emissions of less than 50
ppm calculated as carbon, not including methane and ethane, with no dilution,
as determined in accordance with s.
NR 439.06(3) (a).
(e)
General prohibitions.
The owner or operator of a facility may not atomize any solvent or solvent
solution unless the resulting VOC emissions are controlled by an air pollution
control system that meets one of the requirements of par. (d).
(f)
Alternative compliance
option. In lieu of complying with the requirements in par. (a), the
owner or operator of a facility may use solvents or solvent solutions for

The information required is:
(a) For each operation that is exempt under
sub. (1m) (c), the daily quantity in fluid ounces of VOC-containing aerosol
product used for industrial cleaning operations.
(b) For each operation that is subject to
sub. (2m), the following information as appropriate:
1. The name and identification of each
cleaning material and the associated solvent cleaning activity.
2. The VOC content of each cleaning material,
in pounds per gallon of material, as employed or the VOC composite partial
