Current through August 26, 2024
(1) WORK PRACTICE
IMPLEMENTATION PLAN. The owner or operator of an affected source shall prepare
and maintain a written work practice implementation plan that defines
environmentally desirable work practices for each wood furniture manufacturing
operation and addresses each of the work practice standards in subs. (2) to
(12). The plan shall be developed no more than 60 days after the applicable
compliance date in s.
NR 465.055. The
written work practice implementation plan shall be available for inspection by
the department upon request. If the department determines that the work
practice implementation plan does not adequately address each of the topics
specified in subs. (2) to (12), or that the plan does not include sufficient
mechanisms for ensuring that the work practice standards are being implemented,
the department may require that the owner or operator of the affected source
modify the plan. Revisions or modifications to the plan do not require a
revision of a permit issued under ch. NR 407.
(2) OPERATOR TRAINING COURSE. The owner or
operator of an affected source shall train all personnel, including contract
personnel, who are involved in finishing, gluing, cleaning or washoff
operations, use of manufacturing equipment or implementation of the
requirements of this subchapter. Personnel hired on or after the compliance
date of the standard shall be trained upon hiring. Personnel hired before the
compliance date shall be trained within 6 months of the compliance date of the
standard. All personnel shall be given refresher training annually. The owner
or operator of an affected source shall maintain a copy of the training program
with the work practice implementation plan. The training program shall include,
at a minimum, all of the following:
(a) A
list of all current personnel by name and job description that are required to
be trained.
(b) An outline of the
subjects to be covered in the initial and refresher training for each position
or group of personnel.
(c) Lesson
plans for courses to be given at the initial and the annual refresher training
that include, at a minimum, appropriate application techniques, appropriate
cleaning and washoff procedures, appropriate equipment setup and adjustment to
minimize finishing material usage and overspray and appropriate management of
cleanup wastes.
(d) A description
of the methods to be used to demonstrate and document that personnel have
successfully completed the initial and refresher training.
(3) INSPECTION AND MAINTENANCE PLAN. The
owner or operator of an affected source shall prepare and maintain, with the
work practice implementation plan, a written leak inspection and maintenance
plan for all pumps, valves, flanges and other equipment used to transfer or
apply coatings, adhesives or organic HAP solvents that specifies all of the
following:
(a) An inspection schedule which
specifies a minimum visual inspection frequency of once per month.
(b) Methods for documenting the date and
results of each inspection and any repairs that were made.
(c) The timeframe between identifying the
leak and making the repair, which adheres, at a minimum, to the following
schedule:
1. A first attempt at repair shall
be made no later than 5 calendar days after the leak is detected.
2. Final repairs shall be made within 15
calendar days after the leak is detected, unless the leaking equipment is to be
replaced by a new purchase, in which case repairs shall be completed within 3
months.
(4)
CLEANING AND WASHOFF SOLVENT ACCOUNTING SYSTEM. The owner or operator of an
affected source shall develop an organic HAP solvent accounting form to record
all of the following:
(a) The quantity and
type of organic HAP solvent used each month for washoff and cleaning
operations.
(b) The number of
pieces washed off, and the reason for the washoff.
(c) The quantity of spent organic HAP solvent
generated from each washoff and cleaning operation each month, and whether it
is reused onsite in a process other than cleaning or washoff or disposed of
outside of the facility boundaries.
(5) CHEMICAL COMPOSITION OF CLEANING AND
WASHOFF SOLVENTS. The owner or operator of an affected source may not use
solvents for cleaning or washoff operations that contain any of the pollutants
listed in Table 3 in this subchapter in concentrations that require inclusion
on an MSDS in accordance with the occupational safety and health administration
hazard communication standard in 29 CFR part 1910 Subpart Z, incorporated by
reference in s.
NR 484.03(1).
(6) SPRAY BOOTH CLEANING. The owner or
operator of an affected source may not use compounds containing more than 8.0 %
by weight of VOC for cleaning spray booth components other than conveyors,
continuous coaters and their enclosures, or metal or plastic filters. If the
spray booth coating or other protective material used to cover the booth is
being replaced, the owner or operator may not use more than 1.0 gallon of
organic HAP solvent per booth to prepare the surface of the booth prior to
applying the booth coating.
(7)
STORAGE REQUIREMENTS. The owner or operator of an affected source shall store
finishing, gluing, cleaning and washoff materials in closed
containers.
(8) APPLICATION
EQUIPMENT REQUIREMENTS. The owner or operator of an affected source may use
conventional air spray guns to apply finishing materials only under any of the
following circumstances:
(a) To apply
finishing materials that have a VOC content no greater than 1.0 kg VOC/kg
solids (1.0 lb VOC/lb solids), as applied.
(b) For touchup and repair under any of the
following conditions:
1. The touchup and
repair occurs after completion of the finishing operation.
2. The touchup and repair occurs after the
application of stain and before the application of any other type of finishing
material, and the materials used for touchup and repair are applied from a
container that has a volume of no more than 2.0 gallons.
(c) When the spray gun is aimed and triggered
automatically.
(d) When emissions
from the finishing application station are directed to a control
device.
(e) When the cumulative
total usage of finishing materials applied with conventional air spray guns is
no more than 5.0 % of the total gallons of finishing material used during that
semiannual period.
(f) When the
conventional air gun is used to apply stain on a part for which it is
technically or economically infeasible to use any other spray application
technology. The owner or operator of an affected source shall demonstrate
technical or economic infeasibility by submitting to the department a
videotape, a technical report or other documentation that supports the affected
source's claim of technical or economic infeasibility. The owner or operator
shall use one or both of the following criteria to support a claim that no
other spray application technology is technically or economically feasible:
1. The production speed is too high or the
part shape is too complex for one operator to coat the part and the application
station is not large enough to accommodate an additional operator.
2. The excessively large vertical spray area
of the part makes it difficult to avoid sagging or runs in the stain.
(9) LINE CLEANING. The
owner or operator of an affected source shall pump or drain all organic HAP
solvent used for line cleaning into a container which shall be kept covered
except when actively adding solvent to or removing solvent from the
container.
(10) GUN CLEANING. The
owner or operator of an affected source shall collect all organic HAP solvent
used to clean spray guns into a container which shall be kept covered except
when actively adding solvent to or removing solvent from the
container.
(11) WASHOFF OPERATIONS.
The owner or operator of an affected source shall control emissions from
washoff operations by doing both of the following:
(a) Equipping any tank used for washoff
operations with a cover and keeping the cover closed whenever the tank is not
being used.
(b) Minimizing dripping
by tilting or rotating the part to drain as much solvent as possible.
(12) FORMULATION ASSESSMENT PLAN
FOR FINISHING OPERATIONS.
(a) The owner or
operator of an affected source shall prepare and maintain with the work
practice implementation plan a formulation assessment plan that does all of the
following:
1. Identifies VHAP from the list
presented in Table 4 in this subchapter that are being used in finishing
operations by the affected source.
2. Establishes a baseline level of usage by
the affected source for each VHAP identified in subd. 1. The baseline usage
level shall be the highest annual usage from 1994, 1995 or 1996, for each VHAP
identified in subd. 1., or from another year approved by the department if
annual usage data for those years is not available or if the affected source
was not in operation during those years. For formaldehyde, the baseline level
of usage shall be based on the amount of free formaldehyde present in the
finishing material when it is applied. For styrene, the baseline level of usage
shall be an estimate of unreacted styrene, which shall be calculated by
multiplying the amount of styrene monomer in the finishing material, when it is
applied, by a factor of 0.16. For sources using a control device to reduce
emissions, an adjusted usage may be calculated based on the overall control
efficiency of the control system.
3. Tracks the annual usage of each VHAP
identified in subd. 1. that is present in amounts that require inclusion on an
MSDS in accordance with the occupational safety and health administration
hazard communication standard in 29 CFR part 1910 Subpart Z, incorporated by
reference in s.
NR 484.03(1).
(b) If, after November 1998, the annual usage
of the VHAP identified under par. (a) 1. exceeds the baseline level established
under par. (a) 2., the owner or operator of the affected source shall provide a
written notification to the department that describes the amount of the
increase and explains the reasons for exceedance of the baseline level. Any of
the following explanations relieve the owner or operator from further action,
unless the affected source is not in compliance with any state regulations or
requirements for that VHAP:
1. The exceedance
is no more than 15.0 % above the baseline level.
2. Usage of the VHAP is below the de minimis
level presented in Table 4 in this subchapter for that VHAP. For sources using
a control device to reduce emissions, an adjusted usage based on the overall
control efficiency of the control system may be calculated and used to
demonstrate that the source does not exceed the de minimis level in Table 4 in
this subchapter.
3. The affected
source is in compliance with ch. NR 400 to 499 for the VHAP.
4. The source of the pollutant is a finishing
material with a VOC content of no more than 1.0 kg VOC/kg solids (1.0 lb VOC/lb
solids), as applied.
(c)
If none of the explanations in par. (b) are the reason for the increase, the
owner or operator shall confer with the department to discuss the reason for
the increase and whether there are practical and reasonable technology-based
solutions for reducing the usage. The evaluation of whether a technology is
reasonable and practical shall be based on cost, quality and marketability of
the product, whether the technology is being used successfully by other wood
furniture manufacturing operations, or other criteria mutually agreed upon by
the department and owner or operator. If there are no practical and reasonable
solutions, the owner or operator need take no further action. If there are
solutions, the owner or operator shall develop a plan to reduce usage of the
pollutant to the extent feasible. The plan shall address the approach to be
used to reduce emissions, a timetable for implementing the plan and a schedule
for submitting notification of progress.
(d) If, after November 1998, the owner or
operator of an affected source uses a VHAP of potential concern listed in Table
5 in this subchapter for which a baseline level has not been previously
established, the baseline level shall be established as the de minimis level
provided in Table 5 in this subchapter for that chemical. The owner or operator
shall track the annual usage of each VHAP of potential concern identified in
this paragraph that is present in amounts that require inclusion on an MSDS in
accordance with the occupational safety and health administration hazard
communication standard in 29 CFR part 1910 Subpart Z, incorporated by reference
in s.
NR 484.03(1). If usage of the VHAP of
potential concern exceeds the de minimis level listed in Table 5 in this
subchapter for that chemical, the owner or operator shall provide an
explanation to the department that documents the reason for exceedance of the
de minimis level. If the explanation is not one of those listed in par. (b),
the owner or operator shall follow the procedures in par.
(c).
