A. Carbon Adsorbers

1 All exhaust from the washer, dryer, filter purification system, holding "tanks" and attendant piping and valves must be routed through the carbon adsorber. The carbon adsorber shall be operated at an air flow capacity at least equal to the unrestricted total exhaust gas flow rate of the dry cleaning machines.

2 Any dry cleaner which uses a carbon adsorber to comply with this Chapter must regenerate the carbon bed in accordance with the manufacturer's recommendations, except that the carbon bed shall be regenerated no less than either weekly, or after twenty five (25) loads, whichever period is greater.

a The 100 ppmv emission limit from the carbon adsorber must be met regardless of the regeneration requirements of this Section

b The carbon adsorber must not be bypassed to the atmosphere during regeneration.

B. Refrigerated Condenser System

1 A refrigerated condenser system must be installed on a dry-to-dry machine and reclaimer, provided that the dryer/condenser system is closed to the atmosphere except when articles are being loaded or unloaded at which time a door fan is activated that draws air into the dryer.

2 The condenser shall be monitored in accordance with subsection 5(B). The temperature at the dryer/condenser outlet must be less than or equal to 45°F. This condenser shall be monitored in accordance with section 5(B).
