232-3.5 Operation and maintenance.
(a) Dry cleaning equipment must be maintained and operated to minimize the release of solvent to the environment.
(b) All components of each dry cleaning system must be operated and maintained in accordance with the requirements of this Subpart and any conditions that may be specified on a facility's operating permit. For operations not specifically addressed, the components must be operated and maintained in accordance with the manufacturer's recommendations.
(c) Dry cleaning equipment must be operated, maintained and monitored to comply with the following requirements, as applicable:
(1) Water cooled condensers must be operated and maintained as specified by the manufacturer.
(2) Refrigerated condensers must be maintained and monitored weekly to ensure the control system operates within the high and low pressure limits specified by the manufacturer.
(3) The exhaust damper of a vented machine must be completely closed when the machine is not vented. If malfunctioning, the damper must be repaired or replaced within five working days of detection.
(4) Prior to disposal, cartridge filters and adsorptive cartridge filters must be handled using one of the following methods specified in subparagraphs (i) or (ii) of this paragraph:
(i) 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 solvent, 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 filter housing must be closed as soon as possible to minimize vapor leaks.
(ii) Dried, stripped, sparged, or otherwise treated, within the sealed filter housing, to reduce the volume of solvent contained in the filter.
(5) All steam and condensing coils must be maintained free of lint and hard lint build-up on interior surfaces.
(6) Stills must not vent emissions into the facility unless they operate under a vacuum (vacuum stills). Vacuum stills may only be vented when a vacuum pump exhausts to maintain a continuous vacuum during distillation. All stills must be operated in a manner not to exceed 75 percent of the rated capacity or other alternate value recommended by the manufacturer. Stills must be cooled to 100° F (38° C) or less before being emptied or cleaned.
(7) 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, and subsequent closing, of such traps is done as quickly as possible to minimize solvent vapor emissions.
(8) All parts of the dry cleaning system, including solvent containers, must be kept closed at all times except when access is required for proper operation and maintenance.
(9) Wastewater treatment units managing solvent-contaminated wastewater must be operated and managed in accordance with Parts 360 through 374 and Part 376 of this Title, as applicable.
(i) Carbon filtration units - carbon cartridges must be replaced according to the schedule specified by the manufacturer.
(ii) Evaporators - evaporators treating solvent-contaminated wastewater must be operated to ensure that no liquid solvent or visible emulsion is allowed to vaporize.
(d) Preparedness and prevention.
(1) All dry cleaning operations must be equipped with the following:
(i) adequate spill control equipment including sorbent materials, or alternative method for absorbing spills;
(ii) vapor-proof containers for storing spill-contaminated material; and
(iii) fire control equipment.
(2) Sufficient aisle space must be maintained to allow for proper inspection of the dry cleaning equipment.
(3) A reasonable supply of commonly replaced spare parts for repairing dry cleaning equipment must be available at the dry cleaning facility.
