Section 096-125-5 - Compliance Methods and Monitoring RequirementsA.Carbon Adsorber Systems. The owner/operator of any dry cleaning system using a carbon adsorber to comply with the Control Technology Requirements found in section 3 of this Chapter must establish a program of regular carbon bed desorption and compliance monitoring. 1 Carbon bed desorption shall be conducted 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. The owner/operator shall maintain a record of all carbon bed desorptions which shall include date of desorption and number of loads between desorptions as well as any other evidence demonstrating that the carbon adsorber has been properly installed, operated and maintained. 2 The exhaust of the carbon adsorber shall be measured weekly with a perchloroethylene gas analyzer used in accordance with the manufacturer's instructions. The measurement shall be taken in front of and at a distance of no greater than 3 feet from the dry-cleaning drum opening immediately after the door of the dry cleaning machine is opened and the clothing has been removed. The owner/operator shall maintain a record of all analyzer readings. B.Refrigerated Condenser Systems. The owner/operator of any dry cleaning system using a refrigerated condenser to comply with the Control Technology Requirements found in section 3 of this Chapter must either: 1 measure the temperature on the outlet side of the condenser with a temperature sensor to determine if it is equal to or less than 7.2 [degrees] C (45 [degrees] F) before the end of the cool-down or drying cycle while the gas-vapor stream is flowing through the condenser. The temperature shall be measured at the end of the cool down cycle while the gas is still exhausting using a test port located in the effluent gas stream of the refrigerant condenser or a laser thermometer. This temperature must be recorded weekly, and the temperature sensor shall be used in accordance with the manufacturer's instructions and specifications and shall be designed to measure a temperature of 45°F (7.2°C) to an accuracy of ±2°F (±1.1°C); or2 monitor refrigeration system high pressure and low pressure during the drying phase to determine if they are in the range specified in the manufacturer's operating instructions and record the pressure readings weekly.C.System Inspection of All Unit Types. The owner or operator of a dry cleaner shall determine compliance with the General Maintenance and Performance Standard Requirements subsection (3)(G)(3), on a weekly basis by using a halogenated hydrocarbon detector or perchloroethylene gas analyzer designed to measure 10-500 ppmv of perchloroethylene with an accuracy of ± 5 ppmv that is operated according to manufacturer's instructions. The operator shall place the probe inlet at the surface of each of the following component interfaces where leakage could occur and move it slowly along the interface periphery. 1 Hose and pipe connections, fittings, couplings and valves;2 Machine door gaskets, and seatings;3 Filter head gaskets and seatings;5 Solvent tanks and storage containers;9 Saturated lint from lint basket; 11 All filter housings; and12 All other ancillary equipment; and06- 096 C.M.R. ch. 125, § 5
