Dry Cleaning Operations

​​​​​Commercial cleaning of garments is primarily done by dry cleaning methods that use a non-aqueous solvent.  Two cleaning solvents have dominated the dry cleaning industry -- perchloroethylene and hydrocarbon solvent.  However, several alternative cleaning processes and solvents have emerged that include, but not limited to: high flash point petroleum solvent, carbon dioxide (CO2), volatile methyl siloxane (D5), propylene glycol ether, n-propyl bromide, and water-based cleaning system such as professional wet cleaning.

Perchloroethylene (perc) is the most widely used cleaning solvent in commercial dry cleaning because of its physical and chemical properties.  In 1991, however, the California Air Resources Board (CARB) identified perc as a toxic air contaminant (TAC) associated with environmental and human health risks.  In the same year, the U.S. Environmental Protection Agency (U.S. EPA) added perc in the Section 112 Hazardous Air Pollutants (HAP) list.  Then in 1996, the U.S. EPA removed perchloroethylene from the definition of volatile organic compound (VOC), thus classifying perc as an exempt compound.  Notwithstanding its status as an exempt solvent, perc dry cleaning facilities are still regulated because of their potential adverse health effects.

In December of 2007, CARB amended the Dry Cleaning ATCM​ to:

  • Prohibit the installation of new Perc dry cleaning machines beginning on January 1, 2008

  • Eliminate the use of existing Perc machines at co-residential facilities (facilities that share a wall with, or are located in the same building, as a residence) by July 1, 2010

  • Require that converted machines, and machines that are 15 years or older, be removed from service by July 1, 2010.

  • Require that all Perc machines be removed from service once they become 15 years old (as a result, all remaining Perc machines must be removed from service by January 1, 2023); and


Who Needs a Permit?

  •  Any new or existing dry cleaning operation that uses perchloroethylene, stoddard, or any other cleaner containing VOCs or toxic air contaminants.
  • Any dry cleaning operation that will emit toxic air pollutants or VOCs at levels greater than or equal to 2 pounds in any 24 hour period.
  • Each dry cleaning machine will be permitted individually (one permit per machine).
  • Examples of  exempt cleaning agents (do not require a permit): Carbon Dioxide (CO2), volatile methyl siloxane (D5), and water-based cleaning systems.


Permit Fees 

All permit fees are based on District Rule 301.

When applying for a permit through Online Services, the appropriate Permit Fee schedule will be automatically determined based upon the selection of the General Equipment Description. If you wish to see what the fees are for new equipment prior to applying, please use Schedule 9 in the Permit Fee Schedule to determine the initial application fee. A permit is required for each individual​ dry cleaning machine and therefore a separate fee will be assessed for each unit.
