§ 12-08 Operation and Maintenance Requirements.
RCNY § 12-08
(a)Dry cleaning facilities must be maintained and operated to minimize the release of perc to the environment.
(b)The operator must operate and maintain all components of the dry cleaning system in accordance with the requirements of this Rule and the conditions specified in a facility's operating permit. For operations not specifically addressed, the components must be operated and maintained in accordance with the manufacturer's recommendations. The facility operator must retain, on-site, a copy of the design specifications and the operating manuals for each dry cleaning system and each emission control device located at the dry cleaning facility.
(c)Each operation and maintenance function and the date performed must be recorded on a checklist supplied by the New York State Department of Environmental Conservation. Completed checklists must be maintained on-site for at least five years from the date of the checklist.
(d)Operators must comply with the following operation and maintenance requirements, as applicable: (1) Fourth generation machines.
(i)Refrigerated condensers must be operated in accordance with manufacturer's specifications.
(ii)Integral refrigerated condensers must be operated to ensure that exhaust gases are recirculated until the air-vapor stream temperature is 45°F or less at the outlet. The difference between the temperature of the air-perc gas vapor stream entering and exiting the refrigerated condenser must be greater than or equal to 20°F (11.1°C). The temperature differential must be determined at least weekly with a thermometer with a temperature range of from 32°F (0°C) to 120°F (48.9°C) to an accuracy of ±2°F (1.1°C) (see 15 RCNY § 12-07).
(iii)Vapor adsorbers used with a primary control system or secondary control system must be operated to ensure that exhaust gases are recirculated at the temperature specified for optimum adsorption.
(iv)Cartridge filters and adsorptive cartridge filters must be handled using one of the following methods: (A) Drained in the filter housing, before disposal, 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. 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 steam and condensing coils must be maintained to be free of lint and hard lint build-up on interior surfaces.
(vi)For dry cleaning equipment equipped with a door fan the operator must use a portable velometer or equivalent measurement instrument to verify that the required 100 fpm inward air velocity is maintained through the effective door opening when the loading door is open. The inward air velocity must be checked on a weekly basis.
(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.
(2)Third Generation Machines.
(3)Second Generation Machines.
(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.
(6)The owner or operator of a dry cleaning system must maintain the following equipment as recommended by 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) muck cookers; (vii) stills; (viii) exhaust dampers; (ix) diverter valves; (x) cartridge filter housings; (xi) drying sensors; (7) Preparedness and prevention.
(8)All parts of the 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.
