(a) Specific equipment standards and emission control specifications:
(1) Vapor barriers. Vapor barriers must, at a minimum, enclose the dry cleaning equipment. Vapor barriers can be constructed of polyvinyl chloride, PVC sheet 22 mil thick (0.022 in.), sheet metal, metal foil face composite board, or other equivalent materials that are impermeable to perc vapors. Vapor barriers must be constructed so that all joints and seams are sealed except for inlet makeup air and exhaust openings and entry doors. Entry doors may only be open when a person is entering or exiting the room enclosure.
(2) General exhaust ventilation system. Dry cleaning facilities which are co-located must be equipped with a vapor barrier and with a general exhaust ventilation system that is completely separate from the ventilation system(s) serving other areas of the building. The general exhaust ventilation system must be located near the dry cleaning machinery or connected to a separate room enclosure with a vapor barrier exhausting emissions to the outer air. The system shall be designed and operated to maintain a negative pressure in the room enclosure whenever the dry cleaning machine(s) is operating. This dry cleaning general exhaust ventilation system must be operated at all times when the dry cleaning machine(s) is in operation, and during maintenance operations and must be capable of at least one air change per five minutes.
(3) Door fan/local exhaust ventilation systems.
(i) All first, second and third generation dry cleaning equipment must be equipped with a door fan/local exhaust ventilation system. This system must include a mechanical exhaust fan that is activated when the loading door is open, drawing air from the machine drum causing fresh air to be drawn in through the loading door. A minimum inward air velocity of 100 fpm, must be maintained through the effective door opening area of the loading door of the machine.
(ii) Door fan/local exhaust ventilation systems must not recirculate vapors into the workroom and must be properly vented to the outer air.
(iii) Door fan/local exhaust ventilation emissions must be controlled to a design emission standard of five ppm perc with an in-use maximum compliance standard of 20 ppm.
(4) Process Ventilation Emissions – Interim Standards.
(i) Process ventilation emission points on first and second generation machines that exhaust during the aeration cycle and when the machine door is open must be vented to the outer air above the roof and more than 25 feet from all openings in nearby occupancies.
(ii) Process ventilation emissions from existing first and second generation vented machines having emission controls as part of the original equipment or retrofitted to comply with the 100 ppm perc emission standard effective May 10, 1981 under the repealed version of Title 6, Part 232 of Codes, Rules, and Regulations of the State of New York must continue to meet this standard until such time as retrofitting, replacement, or shutdown is required under this section.
(iii) Process ventilation emissions from existing second generation machines that are retrofitted with control equipment to comply with interim standards established under (b)(3) or (b)(6) in this section must be designed to achieve a perc concentration of five ppm or less in the exhaust and achieve an in-use compliance standard of less than 20 ppm perc in the exhaust.
(iv) The exhaust damper of a vented first or second generation machine must be completely closed when the machine is not being vented, and must not leak vapors into the workroom or the outer air.
(5) Primary emission control systems. Refrigerated condensers or equivalent closed-loop vapor recovery systems must meet the following requirements:
(i) Refrigerated condensers must be capable of achieving an outlet vapor temperature downstream of any by-pass of the condenser less than or equal to 45°F (7.2°C) during the final cool down cycle, and achieve a concentration of 8600 ppm or less perc in the drum upon completion of the drying cycle.
(ii) Refrigerated condensers must have a graduated thermometer, thermocouple or equivalent instrument with a minimum range from 0°F (-18°C) to 150°F (66°C), that measures the temperature of the outlet vapor stream downstream of any by-pass of the condenser, and is easily visible to the operator.
(iii) New third and fourth generation equipment with refrigerated condenser control systems must be equipped with a drying sensor/controller that extends the drying time at least four minutes beyond the point that the solvent recovery rate is less than 40 ml/min or solvent vapor concentration in the drum is less than 8600 ppm perc.
(iv) The refrigerated condenser must be operated with a diverter valve.
(v) Equivalent closed-loop vapor recovery systems or other control device must use a technology that has been demonstrated, pursuant to the requirements of 15 RCNY § 12-17, to achieve at least 90 percent by weight emission reduction based upon the amount of perc entering and leaving the control device.
(6) A secondary control system must:
(i) be designed to function with a primary control system complying with all requirements for third generation equipment.
(ii) be capable of reducing the perc concentration in the drum from 8600 ppm or greater to 300 ppm.

(7) Spill containment. All new third and fourth generation, or used, reinstalled dry cleaning equipment must be equipped with a spill containment system capable of containing 125 percent of the capacity of the largest dry cleaning perc tank or vessel associated with the dry cleaning machine.
(b) To determine which standards will apply to a particular dry cleaning facility, first determine whether the facility is new or existing. Then determine whether the facility is a stand-alone or is co-located. If co-located, determine whether it is in a commercial or residential building.

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. In performing such a transfer the filter housing must be closed as soon as possible to minimize vapor leaks. The general exhaust ventilation system must be operated during this activity.
(B) Dried, stripped, sparged, or otherwise treated, within the sealed filter housing, to reduce the volume of perc contained in the filter.
(v) All water-cooled condensers must include temperature gauges installed in the inlet and outlet water lines of the condensing coil on the dryer. The temperature difference must be maintained according to manufacturer's specifications.
(vi) Azeotropic control devices must be maintained and operated in accordance with manufacturer's instructions and specifications.
(vii) Test carbon absorber exhaust vents daily using colorimetric detector tubes or portable gas detectors. These absorbers shall be stripped periodically and maintained so that the perc concentration in the exhaust air does not exceed 20 ppm.
(4) First generation machines. An existing facility with a transfer machine operating a full-sized carbon adsorber or azeotropic control device, and cartridge filters must meet the applicable requirements of paragraph (d)(3) of this section.
(5) Ancillary Equipment.
(i) All filter muck must be treated in a still or muck cooker, which routes perc-contaminated vapors to a condenser or other control device and recycles condenser vapors into the machine. Still or muck cooker emissions must not be vented into the facility. Any still or muck cooker must not be operated in a manner that exceeds 75 percent of its capacity or other alternate value recommended by the manufacturer. Any still or muck cooker must be cooled to 100°F (38°C) or less before being emptied or cleaned.
(ii) Button and lint traps must be cleaned each working day and the lint must be placed in a tightly sealed container. Whenever possible such operations must be performed so that the opening of such traps is done quickly with the local or general exhaust ventilation system operating to minimize perc emissions.
(iii) Perc-contaminated wastewater treatment units.
(A) Carbon filtration units – carbon cartridges must be replaced according to a schedule as specified by the manufacturer to assure an effluent quality that does not exceed 20 ppb perc.
(B) Evaporators – perc contaminated wastewater evaporators must be operated to ensure that no liquid perc or visible emulsion is allowed to vaporize.
(iv) Dip tanks and drying cabinets must be exhausted to maintain an inward air flow, and be maintained under negative pressure, to ensure that fugitive emissions will be no greater than 50 ppm. Vented emissions from dip tanks and drying cabinets must not exceed 20 ppm.
