Section 570

ASBESTOS CONTROL STANDARDS

570.1

The Board of Directors of the Northwest Clean Air Agency recognize that asbestos is a serious health hazard. Any asbestos fibers released into the air can be inhaled and can cause lung cancer, pleural mesothelioma, peritoneal mesothelioma or asbestosis. The Board has, therefore, determined that any asbestos emitted to the ambient air is air pollution. Because of the seriousness of the health hazard, the Board of Directors has adopted this regulation to control asbestos emissions from asbestos removal projects in order to protect the public health. In addition, the Board has adopted these regulations to coordinate with the EPA asbestos NESHAP, the OSHA asbestos regulation, the Washington Department of Labor and Industries asbestos regulations, the Washington Department of Ecology Dangerous Waste regulation, and the solid waste regulations of Island, Skagit and Whatcom Counties.

7. Muck cookers;

8. Stills;

9. Cartridge filter housings.

c. Conduct vapor leak inspections monthly while the dry cleaning system is running using a halogenated hydrocarbon detector or perchloroethylene gas analyzer that is operated according to the manufacturer’s instructions. The operator shall place the probe in let at the surface of each component interface where leakage could occur and move it slowly along the interface periphery. Any inspection conducted according to this paragraph shall satisfy the requirements to conduct an inspection for perceptible leaks as described in 590.41(a).

d. All perchloroethylene dry cleaning systems shall be in compliance with 590.41(c) by July 28, 2008.

e. All perceptible and/or vapor leaks shall be repaired within 24 hours of detection. If repair parts must be ordered to repair a leak, the parts shall be ordered within 2 working days of detecting the leak, and the repair parts shall be installed within 5 working days after receipt.

590.42

Drain cartridge filters in their housing or other sealed container for at least 24 hours before discarding the cartridges;

590.43

Close the door of each dry cleaning machine except when transferring articles to or from the machine;

590.44

Store all perchloroethylene, and wastes containing perchloroethylene, in a closed container; and

590.45

Operate and maintain the dry cleaning system according to the manufacturer’s specifications and recommendations.

590.46

Keep a copy on-site of the design specifications and operating manuals for all dry cleaning equipment.

590.47

590.5

Requirements for Refrigerated Condensers. It shall be unlawful for any person to cause or allow the operation of any perchloroethylene dry cleaning system using a refrigerated condenser unless all of the following conditions are met:

590.51

The air temperature at the outlet of the refrigerated condenser installed on a dry-to-dry machine must reach 45°F (7°C) or less during the cool down period. Compliance shall be determined by continuously monitoring the outlet temperature during the cool-down period using a permanently installed temperature sensor that is accurate to within 2°F (1°C);

590.52

The difference between the air temperature at the inlet and outlet of a refrigerated condenser installed on a washer must be greater than or equal to 20°F(11°C). Compliance shall be determined by continuously monitoring the inlet and outlet temperatures during the cool-down period using permanently installed temperature sensors that are accurate to within 2°F(1°C);

590.53

The refrigerated condenser shall be operated so that air drawn into the dry cleaning machine does not pass through the refrigerated condenser when the door of the machine is open; and

590.54

The refrigerated condenser shall not vent the air-perchloroethylene gas-vapor stream while the dry cleaning machine drum is rotating.

590.6

Requirements for Carbon Adsorbers. It shall be unlawful for any person to cause or allow the operation of any perchloroethylene dry cleaning system using a carbon adsorber unless all of the following conditions are met:

590.61

The concentration of perchloroethylene at the exhaust of the carbon adsorber shall not exceed 100 ppm while the dry cleaning machine is venting to the carbon adsorber at the end of the last dry cleaning cycle prior to desorption of the carbon adsorber; and

590.62

Compliance shall be determined by weekly measurements of the concentration of perchloroethylene at the outlet of the carbon absorber using a halogenated hydrocarbon detector or perchloroethylene gas analyzer that is accurate to within 25 ppm.

590.7 Recordkeeping.

Each dry cleaning facility shall have an Operation and Maintenance Plan and the following records which shall be kept on-site and available for inspection upon request by the NWCAA.

590.71 A record of dates and results of all monitoring, inspections, and repair of the dry cleaning system.

590.72 If a refrigerated condenser is used on a dry-to-dry machine, a weekly record of the air temperature measured at the outlet of the refrigerated condenser during the cool-down period to verify compliance with Subsection 590.51.

590.73 If a carbon adsorber is used on a dry cleaning system, a weekly record of outlet perchloroethylene concentration to verify compliance with 590.61.

590.74 A record of the volume of perchloroethylene purchased each month including receipts of perchloroethylene purchases and a calculation of the amount of perchloroethylene purchased over the previous 12 months. All receipts of perchloroethylene purchases must be retained for 5 years.

590.8 Prohibitions.

a. It shall be unlawful to operate a multi-machine dry cleaning operation in which washing and drying are performed in different machines (transfer system) after December 31, 1999.

b. After July 27, 2006 it shall be unlawful to install or reconstruct a dry cleaning system in a building with a residence.

c. After December 21, 2020, it shall be unlawful to operate a dry cleaning system that is located in a building with a residence.
