Current through Register Vol. 46, No. 28, July 10, 2024
(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.
