(1) APPLICABILITY.
(a) This section applies to the application
areas, flashoff areas, and ovens of automobile and light-duty truck
manufacturing plants involved in prime, topcoat, and final repair coating of
metallic front end and main body parts at any facility located in the county of
Kenosha, Milwaukee, Ozaukee, Racine, Sheboygan, Washington, or Waukesha if VOC
emissions from the prime, topcoat, and final repair coating and related
cleaning activities at the facility, before consideration of controls, equal or
exceed 3 tons per year on a 12 consecutive month rolling basis.
(b) Subsections (2) to (5) apply to the
coating operations described in par. (a) at any automobile and light-duty truck
manufacturing facility located in the county of Brown, Calumet, Dane, Dodge,
Door, Fond du Lac, Jefferson, Kewaunee, Manitowoc, Outagamie, Rock, Walworth,
and Winnebago if VOC emissions from all coating operations described in par.
(a) at the facility, before consideration of controls, equal or exceed 6.8
kilograms (15 pounds) in any one day.
(c) Subsections (2) to (5) apply to coating
operations as described in par. (a) at any automobile and light-duty truck
manufacturing facility not subject to par. (a) or (b) if total VOC emissions
from the facility, before consideration of controls, equal or exceed 100 tpy.
(d) Subsections (2) to (5) do not
apply to the coating of wheels, trunk interiors, steering columns, or
nonmetallic parts; sealers; nonpriming anti-rust coatings; or processes,
coatings, or inks described in s.
NR 422.03(5) and
(7).
(2) EMISSION LIMITATIONS-ENAMELS. No owner or
operator of an automobile surface coating line which, prior to January 1, 1979,
used an enamel coating system, may cause, allow or permit the emission of any
VOCs in excess of:
(a) After December 31,
1983, 0.14 kilograms per liter of coating (1.2 pounds per gallon), excluding
water, from an electrodeposition prime coat or equivalent coating
line.
(b) After December 31, 1982,
0.34 kilograms per liter of coating (2.8 pounds per gallon), excluding water,
from a spray primer-surfacer coating line.
(d) After December 31, 1985, 0.34 kilograms
per liter of coating (2.8 pounds per gallon), excluding water, from a topcoat
coating line.
(e) After December
31, 1982, 0.58 kilograms per liter of coating (4.8 pounds per gallon),
excluding water, from any final repair coating line.
(3) EMISSION LIMITATIONS-LACQUERS. No owner
or operator of an automobile surface coating line which, prior to January 1,
1979, used a lacquer coating system, may cause, allow or permit the emission of
any VOCs in excess of:
(b) After December 31,
1982, 0.14 kilograms per liter of coating (1.2 pounds per gallon), excluding
water, from an electrodeposition prime coat coating line.
(d) After December 31, 1986, 0.34 kilograms
per liter of coating (2.8 pounds per gallon), excluding water, from a spray
primer-surfacer coating line.
(g)
After December 31, 1986, 0.34 kilograms per liter of coating (2.8 pounds per
gallon), excluding water, from a topcoat coating line.
(i) After December 31, 1986, 0.58 kilograms
per liter of coating (4.8 pounds per gallon), excluding water, from any final
repair coating line.
(4)
EMISSION LIMITATIONS-TRUCKS. No owner or operator of a light-duty truck surface
coating line may cause, allow or permit the emission of any VOCs in excess of:
(b) After December 31, 1982, 0.14 kilograms
per liter of coating (1.2 pounds per gallon), excluding water, from an
electrodeposition prime coat coating line.
(d) After December 31, 1987, 0.34 kilograms
per liter of coating (2.8 pounds per gallon), excluding water, from a spray
primer-surfacer coating line.
(f)
After December 31, 1987, 0.34 kilograms per liter of coating (2.8 pounds per
gallon), excluding water, from a topcoat coating line.
(g) After December 31, 1982, 0.58 kilograms
per liter of coating (4.8 pounds per gallon), excluding water, from any final
repair coating line.
(5)
EMISSION RATE AVERAGING. Each emission limit in this section may be interpreted
as a weighted daily average, if specified in an approved compliance plan. The
emission limits are referenced to waterborne coatings conventionally applied.
Any coating line which achieves an equivalent emission rate per unit area
coated shall be deemed in compliance.
(6) WORK PRACTICES. Beginning on March 1,
2013, the owner or operator of a facility subject to this section shall do all
of the following:
(a) Minimize VOC emissions
from cleaning of storage, mixing and conveying equipment.
(b) Develop and implement a work practice
plan to minimize VOC emissions from cleaning and purging of equipment
associated with all coating operations. The plan shall specify practices and
procedures for the following operations, at a minimum:
1. Vehicle body wiping.
2. Coating line purging.
3. Flushing of coating systems.
4. Cleaning of spray booth grates.
5. Cleaning of spray booth walls.
6. Cleaning of spray booth
equipment.
7. Cleaning of external
spray booth areas.
