(1) APPLICABILITY AND DESIGNATION OF AFFECTED
FACILITY.
(a) The provisions of this section
are applicable to the following affected facilities located at a petroleum dry
cleaning plant with a total manufacturer's rated dryer capacity equal to or
greater than 38 kilograms (84 pounds): Petroleum solvent dry cleaning dryers,
washers, filters, stills and settling tanks.
1. When the affected facility is installed in
an existing plant that is not expanding the manufacturer's rated capacity of
its petroleum solvent dryer(s) the total manufacturer's rated dryer capacity is
the summation of the manufacturer's rated capacity for each existing petroleum
solvent dryer.
2. When the affected
facility is installed in a plant that is expanding the manufacturer's rated
capacity of its petroleum solvent dryers the total manufacturer's rated dryer
capacity is the summation of the manufacturer's rated dryer capacity for each
existing and proposed new petroleum solvent dryer.
3. When the affected facility is installed in
a new plant the total manufacturer's rated dryer capacity is the summation of
the manufacturer's rated dryer capacity for each proposed new petroleum solvent
dryer.
4. The petroleum solvent
dryers considered in the determination of the total manufacturer's rated dryer
capacity are those new and existing dryers in the plant that will be in service
at any time after the proposed new source or modification commences
operation.
(b) Any
facility under par. (a) that commences construction or modification after
December 14, 1982, is subject to the requirements of this section, except that
a dryer installed between December 14, 1982 and September 21, 1984, in a plant
with an annual solvent consumption level of less than 17,791 liters (4,700
gallons), is exempt from the requirements of this section.
(2) DEFINITIONS. As used in this
section, terms not defined in this subsection have the meanings given in s.
NR 440.02.
(a)
"Cartridge filter" means a discrete filter unit containing both filter paper
and activated carbon that traps and removes contaminants from petroleum solvent
together with the piping and ductwork used in the installation of this
device.
(b) "Dryer" means a machine
used to remove petroleum solvent from articles of clothing or other textile or
leather goods, after washing and removing of excess petroleum solvent, together
with the piping and ductwork used in the installation of this device.
(c) "Manufacturer's rated dryer capacity"
means the dryer's rated capacity of articles, in pounds or kilograms of
clothing articles per load, dry basis, that is typically found on each dryer on
the manufacturer's name-plate or in the manufacturer's equipment
specifications.
(d) "Perceptible
leaks" means any petroleum solvent vapor or liquid leaks that are conspicuous
from visual observation or that bubble after application of a soap solution
such as pools or droplets of liquid, open containers or solvent, or solvent
laden waste standing open to the atmosphere.
(e) "Petroleum dry cleaner" means a dry
cleaning facility that uses petroleum solvent in a combination of washers,
dryers, filters, stills and settling tanks.
(f) "Settling tank" means a container that
gravimetrically separates oils, grease and dirt from petroleum solvent together
with the piping and ductwork used in the installation of this device.
(g) "Solvent filter" means a discrete solvent
filter unit containing a porous medium that traps and removes contaminants from
petroleum solvent together with the piping and ductwork used in the
installation of this device.
(h)
"Solvent recovery dryer" means a class of dry cleaning dryers that employs a
condenser to condense and recover solvent vapors evaporated in a closed-loop
stream of heated air together with the piping and ductwork used in the
installation of this device.
(i)
"Still" means a device used to volatilize, separate and recover petroleum
solvent from contaminated solvent together with the piping and ductwork used in
the installation of this device.
(j) "Washer" means a machine which agitates
fabric articles in a petroleum solvent bath and spins the articles to remove
the solvent together with the piping and ductwork used in the installation of
this device.
(3)
STANDARDS FOR VOLATILE ORGANIC COMPOUNDS.
(a)
Each affected petroleum solvent dry cleaning dryer that is installed at a
petroleum dry cleaning plant shall be a solvent recovery dryer. The solvent
recovery dryers shall be properly installed, operated and maintained.
(b) Each affected petroleum solvent filter
that is installed at a petroleum dry cleaning plant shall be a cartridge
filter. Cartridge filters shall be drained in their sealed housings for at
least 8 hours prior to their removal.
(c) Each manufacturer of an affected
petroleum solvent dryer shall include leak inspection and leak repair cycle
information in the operating manual and on a clearly visible label posted on
each affected facility. Such information should state:
To protect against fire hazards, loss of valuable solvents
and emissions of solvent to the atmosphere, periodic inspection of this
equipment for evidence of leaks and prompt repair of any leaks is recommended.
The Wisconsin Department of Natural Resources recommends that the equipment be
inspected every 15 days and all vapor or liquid leaks be repaired within the
subsequent 15 day period.
Note: The administrator may approve the use of equipment of
procedures that have been demonstrated to be equivalent, in terms of reducing
VOC emissions, to those prescribed for compliance in this section, under
40 CFR
60.623.
(5) TEST METHODS AND PROCEDURES. Each owner
or operator of an affected facility subject to the provisions of sub. (3) (a)
shall perform an initial test to verify that the flow rate of recovered solvent
from the solvent recovery dryer at the termination of the recovery cycle is no
greater than 0.05 liters per minute. This test shall be conducted for a
duration of no less than 2 weeks during which no less than 50% of the dryer
loads shall be monitored for their final recovered solvent flow rate. The
suggested point for measuring the flow rate of recovered solvent is the outlet
of the solvent-water separator. Near the end of the recovery cycle the entire
flow of recovered solvent should be diverted to a graduated cylinder. As the
recovered solvent collects in the graduated cylinder the elapsed time is
monitored and recorded in periods of greater than or equal to one minute. At
the same time the volume of solvent in the graduated cylinder is monitored and
recorded to determine the volume of recovered solvent that is collected during
each time period. The recovered solvent flow rate is calculated by dividing the
volume of solvent collected per period by the length of time elapsed during the
period and converting the result with appropriate factors into units of liters
per minute. The recovery cycle and the monitoring procedure should continue
until the flow rate of solvent is less than or equal to 0.05 liter per minute.
The type of articles cleaned and the total length of the cycle should then be
recorded.
(6) RECORDKEEPING
REQUIREMENTS. Each owner or operator of an affected facility subject to the
provisions of this section shall maintain a record of the performance test
required under sub. (5).
