PURPOSE: This rule restricts the emissions of perchloroethylene from dry cleaning installations.

1. (1) Application. This rule shall apply throughout St. Louis City and Jefferson, St. Charles, Franklin and St. Louis Counties.
2. (2) Definitions of certain terms specified in this rule may be found in 10 CSR 10-6.020.

3. (3) General. No owner or operator shall cause or allow the operation of any perchloroethylene dry cleaning installation unless the facility meets the following requirements:

   1. (A) The entire dryer exhaust shall be vented through—

      1. 1. A carbon adsorber so that the maxi-

mum solvent concentration in the vent from the adsorber shall not exceed one hundred parts per million by volume (100 ppmv) before dilution; or

1. 2. An equally effective control device as

approved by the director;

1. (B) There shall be no liquid leakage from the system; and

2. (C) Filter and Distillation Wastes.

   1. 1. The residue from all diatomaceous

earth filters shall be cooked or treated so that wastes shall not contain more than twentyfive kilograms (25 kg) (55 lbs.) of solvent per one hundred kilograms (100 kg) (220 lbs.) of wet waste material.

1. 2. The residue from all solvent still shall

not contain more than sixty kilograms (60 kg) (132 lbs.) of solvent per one hundred kilograms (100 kg) (220 lbs.) of wet waste material.

1. 3. Filtration cartridges shall be drained

in the filter housing for twenty-four (24) hours or in other sealed container before being discarded. The drained cartridges should be dried in the dryer tumbler after draining if at all possible.

1. (4) Exceptions. Subsection (3)(A) of this rule shall not be applicable to installations which clean forty thousand pounds (40,000 lbs.) of clothing or less per year, coin-operated installations, installations where a control device cannot be accommodated because of inadequate space or installations where no or insufficient steam capacity is available to desorb adsorbers. The director may exclude other installations from the provisions of subsection (3)(A) of this rule if it is demonstrated that other hardships or economics justify an exclusion.

2. (5) Compliance Schedules.

   1. (A) The owner or operator of a perchloroethylene dry cleaning installation subject to subsection (3)(A) of this rule must meet the applicable increments of progress in the following schedule:

      1. 1. Award contracts, issue purchase

orders or otherwise order the emission control system and process equipment, before April 1, 1981;

1. 2. Complete installation of the emission

control and process equipment before March 1, 1982;

1. 3. Achieve final compliance, determined

in accordance with section (5), before April 1, 1982; and

1. 4. In the event that equipment cannot be

delivered prior to February 1, 1982, and the owner or operator placed the order prior to April 1, 1981, the final compliance date shall be sixty (60) days following delivery of the equipment.

1. (B) The owner or operator of a perchloroethylene dry cleaning installation subject to this rule must comply with the opera- 10 CSR 10-5

tional and maintenance provisions of subsections (3)(B) and (C) by April 1, 1981.

1. (6) Compliance Methods.

   1. (A) Compliance with paragraph (3)(C)3. of this rule shall be determined by means of visual inspection.

   2. (B) Compliance with subsection (3)(A) of this rule shall be determined by—

      2. 2. The testing method referenced in 10

CSR 10-6.030(14)(A).

1. (C) Compliance with subsection (3)(B) of this rule shall be determined by means of a visual inspection of the following components: hose connections, unions, couplings and valves; machine door gaskets and seatings; filter and head gasket and seatings; pumps; basetanks and storage containers; water separations; filter sludge recovery distillation units; diverter valves; saturated lint from lint basket; and cartridge filters.
2. (D) Compliance with paragraphs (3)(C)1. and 2. of this rule shall be determined by the testing method referenced in 10 CSR 10- 6.040(8).

1. (7) Recordkeeping.

   1. (A) The owner or operator shall keep daily records of visual inspections, waste material disposal and testing results of paragraph (6)(B)2. and subsection (6)(D).
