Current through June 24, 2024
(1) APPLICABILITY.
(a) The provisions of this section apply to
				the owner or operator of each dry cleaning facility that uses
				perchloroethylene.
(b) Each dry
				cleaning system that commences construction or reconstruction on or after
				December 9, 1991, shall be in compliance with the provisions of this section
				beginning on July 1, 1995 or immediately upon startup, whichever is later,
				except for dry cleaning systems constructed or reconstructed before September
				22, 1993, which shall comply with sub. (3) (b) beginning on September 23, 1996,
				and shall comply with other provisions of this section by July 1,
				1995.
(c) Each dry cleaning system
				that commenced construction or reconstruction before December 9, 1991, shall
				comply with subs. (3) (c), (d), (i), (j), (k), (L) and (m), (4) (d) and (5)
				(b), (d) 1. to 4. and (e) beginning on July 1, 1995, and shall comply with
				other provisions of this section by September 23, 1996.
(d) Each existing dry-to-dry machine and its
				ancillary equipment located in a dry cleaning facility that includes only
				dry-to-dry machines and each existing transfer machine system and its ancillary
				equipment, as well as each existing dry-to-dry machine and its ancillary
				equipment, located in a dry cleaning facility that includes both transfer
				machine systems and dry-to-dry machines is exempt from subs. (3), (4) and (5),
				except subs. (3) (c), (d), (i), (j), (k), (L) and (m), (4) (d) and (5) (b), (d)
				1. to 4. and (e), if the total perchloroethylene consumption of the dry
				cleaning facility is less than 530 liters (140 gallons) per year. Consumption
				is determined according to sub. (4) (d).
(e) Each existing transfer machine system and
				its ancillary equipment located in a dry cleaning facility that includes only
				transfer machine systems is exempt from subs. (3), (4) and (5), except subs.
				(3) (c), (d), (i), (j), (k), (L), and (m), (4) (d) and (5) (b), (d) 1. to 4.
				and (e), if the perchloroethylene consumption of the dry cleaning facility is
				less than 760 liters (200 gallons) per year. Consumption is determined
				according to sub. (4) (d).
(f) If
				the total yearly perchloroethylene consumption of a dry cleaning facility
				determined according to sub. (4) (d) is initially less than the amounts
				specified in par. (d) or (e), but later exceeds those amounts, the existing dry
				cleaning systems in the dry cleaning facility must comply with subs. (3), (4)
				and (5) by 180 calendar days from the date that the facility determines it has
				exceeded the amounts specified, or by September 23, 1996, whichever is
				later.
(g) A dry cleaning facility
				is a major source if the facility emits or has the potential to emit more than
				9.1 megagrams per year (10 tons per year) of perchloroethylene to the
				atmosphere. In lieu of measuring or determining a facility's potential to emit
				perchloroethylene emissions, a dry cleaning facility is a major source in
				either of the following cases:
1. If it
				includes only dry-to-dry machines and has a total yearly perchloroethylene
				consumption greater than 8,000 liters (2,100 gallons) as determined according
				to sub. (4) (d).
2. If it includes
				only transfer machine systems or both dry-to-dry machines and transfer machine
				systems and has a total yearly perchloroethylene consumption greater than 6,800
				liters (1,800 gallons) as determined according to sub. (4) (d).
(h) A dry cleaning facility is an
				area source if it does not meet the conditions of par. (g).
(i) If the total yearly perchloroethylene
				consumption of a dry cleaning facility determined according to sub. (4) (d) is
				initially less than the amounts specified in par. (g), but then exceeds those
				amounts, the dry cleaning facility becomes a major source and all dry cleaning
				systems located at that dry cleaning facility must comply with the appropriate
				requirements for major sources under subs. (3), (4) and (5) by 180 calendar
				days from the date that the facility determines it has exceeded the amount
				specified, or by September 23, 1996, whichever is later.
(j) All coin-operated dry cleaning machines
				are exempt from the requirements of this section.
