!Q) Minnesota Pollution Control Agency ------~ AQ Doc. # 5.03 May 1999 Emission Standards for Dry Cleaning Facilities Facts about The U. S. Environmental Protection Agency (EP A) has set new standards for the control of erchloroeth lene releases from d cleanin facilities. Definitions used: OC means degrees Celsius. CA means carbon 'adsorber. This is a bed of activated carbon into which an air-perchloroethylene gas-vapor stream is routed and which adsorbs the perchloroethylene on the carbon. Carbon adsorbers are often called "sniffers." Colorimetric detector tube means a glass tube (sealed prior to use), containing material impregnated with a chemical that is sensitive to perchloroethylene and is designed to measure the concentration ofperchloroethylene in air. Dry to dry machine means a one-machine dry cleaning operation in which washing and drying are performed in the same machine. Existing means began construction or reconstruction before December 9, 1991 (the date the proposed rule was published in the Federal Register). OF means degrees Fahrenheit Fugitive emissions means emissions that couldn't reasonably be vented through a vent, stack, or similar device. New means began construction or reconstruction on or after December 9, 1991. ppm means parts per million. Process vent controls means devices used to control emissions from a vent, stack, or similar device. RC means refrigerated condenser. This is a system into which an air-perchloroethylene gas-vapor stream is routed and the perchloroethylene is condensed by cooling the gas-vapor stream. Refrigerated condensers are often called "chillers." Transfer machine system means a multiple-machine dry cleaning operation in which washing and drying are performed in different machines. Examples include, but are not limited to: (1) a washer and dryer, (2) a washer and reclaimer, or (3) a dry to dry machine and reclaimer. Perchloroethylene, often referred to as "perc" or "PCE," is suspected of causing cancer in humans. This fact sheet is designed to help you understand these new regulations. . These emission standards are different from hazardous waste regulations. These are based on use of perc, not generation of perc- related drained spent cartridge filters, still bottoms, or filter muck waste. . These emission standards are different from the Minnesota Occupational Safety and Health Administration (OSHA) regulations that set a time-weighted average of 25 ppm of perc as the exposure limit for employees. These requirements do not apply to coin- operated dry cleaning facilities. . Minnesota Pollution Control Agency, 520 Lafayette Rd.
