232-2.6 Operation and maintenance.
(a) Perc dry cleaning facilities must be maintained and operated to minimize the release of perc to the environment.
(b) Trained operators must operate and maintain all components of the perc dry cleaning system in accordance with the requirements of this Subpart and the conditions specified in the facility's operating permit. For operations not specifically addressed in this Subpart, the components must be operated and maintained in accordance with the manufacturer's recommendations.
(c) Trained operators must complete all functions on the operational and maintenance checklist supplied by the department and note the action taken, the date it was performed and the trained operator's initials on the form. Completed checklists must be maintained on-site for at least five years from the last inspection date recorded.
(d) Trained operators must comply with the following operation and maintenance requirements, as applicable:
(1) Third and fourth generation perc dry cleaning machines.
(i) Refrigerated condensers must be operated and maintained in compliance with section 232-2.4(a)(4) of this Subpart and otherwise in accordance with manufacturer's specifications.
(ii) Carbon adsorbers installed on fourth generation machines must be operated to ensure that exhaust gases are recirculated at the operating temperature designed for the equipment, or specified by the manufacturer, for optimum adsorption.
(iii) Cartridge filters and adsorptive cartridge filters must be handled using one of the following methods prior to disposal:
(a) Drained in the filter housing for no less than 24 hours for cartridge filters and 48 hours for adsorptive cartridge filters. If the filters are then transferred to a separate device to further reduce the volume of perc, this treatment must be done in a system that routes any vapor to a primary closed-loop control system, with no exhaust to the atmosphere. When performing such a transfer, the general exhaust ventilation system must be operating and the filter housing must be closed as soon as possible to minimize vapor leaks.
(b) Dried, stripped, sparged, or otherwise treated, within the sealed filter housing, to reduce the volume of perc contained in the filter.
(iv) All steam and condensing coils must be maintained free of lint and hard lint build-up on interior surfaces.
(v) Button and lint traps must be cleaned on the manufacturer’s suggested intervals and at least once each working day and the lint must be placed in a tightly sealed container. Operations must be performed so that the opening of such traps is done as quickly as possible with the local or general exhaust ventilation system operating to minimize perc emissions.
(2) Ancillary equipment.
(i) Stills and muck cookers must not vent emissions into the facility nor be operated in a manner that exceeds 75 percent of the rated capacity or other alternate value recommended by the manufacturer. Stills and muck cookers must be cooled to 100° F (38° C) or less before being emptied or cleaned.
(ii) Wastewater treatment units treating perc-contaminated waste.
(a) Carbon filtration units - carbon cartridges must be replaced in accordance with manufacturer's specifications.
(b) Evaporators - evaporators treating perc-contaminated wastewater must meet the requirements of section 232-2.7(b) of this Subpart and be operated to ensure that no liquid perc or visible emulsion is allowed to vaporize.
(3) The following equipment must be maintained according to the recommended manufacturer's specifications:
(i) hose and pipe connections, fittings, couplings, and valves;
(ii) door gaskets and seatings;
(iii) filter gaskets and seatings;
(iv) pumps;
(v) water separators;
(vi) stills;
(vii) cartridge filter housings; and
(viii) drying sensors.
(4) Preparedness and prevention.
(i) All perc dry cleaning operations must be equipped with the following:
(a) adequate spill control equipment including sorbent materials, or an alternative method for absorbing spills;
(b) vapor-proof containers for storing spill-contaminated material; and
(c) fire control equipment.
(ii) Sufficient aisle space must be maintained to allow proper inspection of the dry cleaning equipment.
(iii) A reasonable supply of commonly replaced spare parts for repairing perc dry cleaning equipment must be available at the dry cleaning facility.
(5) All parts of the perc dry cleaning system, including solvent containers where perc may be emitted to the atmosphere, must be kept closed at all times except when access is required for proper operation and maintenance.
(6) Perc process tanks must be refilled using a closed-loop delivery system.
