New York Codes, Rules and Regulations › Title 6 - DEPARTMENT OF ENVIRONMENTAL CONSERVATION › Chapter III - AIR RESOURCES › Subchapter A - PREVENTION AND CONTROL OF AIR CONTAMINATION AND AIR POLLUTION › Part 232 - Dry Cleaning Facilities › Subpart 232-3 - Alternative Solvent Dry Cleaning Equipment › Section 232-3.5 - Operation and maintenance

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