Inspection, Monitoring & Record-keeping

Required by all drycleaners using perc

All drycleaners who use perc, regardless of the amount or type of machinery, must follow these rules for operations, inspections, monitoring and record-keeping.

Operation

• All drycleaning equipment must be operated and maintained according to manufacturer's instructions.
• Operation and maintenance manuals for all drycleaning equipment must be kept on hand in the plant
• Cartridge filters must be drained in their housing or in sealed containers for at least 24 hours.
• Machine doors must be kept shut when clothing is not being transferred.
• All perc and wastes containing perc must be kept in covered containers with no leaks.

Inspections

Institute a leak detection and repair program to inspect all drycleaning equipment for leaks that are obvious from sight, smell or touch. The inspection program should be conducted weekly except for plants that are not required to have emission control equipment; those plants must conduct the inspections every other week.

Inspections should include the following: Hose and pipe connections, fittings, couplings and valves; door gaskets and seatings; filter gaskets and seatings; pumps, solvent tanks and containers; water separators, muck cookers; stills, exhaust dampers, diverter valves; cartridge filter housings.

Leaks must be repaired within 24 hours after they are found. If parts are needed for repairs, they must be ordered within two working days of discovering the leak and installed within five working days after receiving them.

Monitoring

• Where add-on refrigeration units are in use, weekly measurements of the inlet and outlet stream using temperature sensors must be taken. The difference between the vapor stream from the washer and the vapor stream exiting the refrigerated condenser must be greater than or equal to 20 degrees F. The outlet temperature from the dry-to-dry machine, dryer or reclaimer must be equal to or less than 45 degrees F.
• Where add-on carbon vapor adsorbers are in use, measurements must be made weekly of the exhaust stack using a colorimetric detector tube. The exhaust from the carbon adsorber can not exceed 100 parts per million. The carbon adsorber test is not required for existing machines until September 22, 1996. However, if the compliance report is submitted earlier, the testing must start immediately.

Recordkeeping

• A log of the amount of perc purchased must be kept. Add together all perc purchases for each of the previous 12 months for all the drycleaning machines in the plant. As each new calendar month begins, add the new perc purchases for the past month and subtract the perc purchases in the oldest of the 12 months. This total represents the yearly perc purchases for purposes of compliance reporting. Keep a month-by-month record of perc purchases, even for months in which no purchases were made.
• A log of the weekly or biweekly inspections must be kept along with records of any repairs made to correct leaks.
• A log of the results of temperature testing for add-on refrigeration units or the colorimetric detector tube measurements for add-on carbon adsorber units must be kept when those tests are required.
