In 1993, the California Air Resources Board (ARB) adopted two regulations that affect dry cleaners in California. Those regulations are codified in Title 17 of the California Code of Regulations (CCR), Sections 93109 and 93110. Section 93109, the Airborne Toxic Control Measure for Emissions of Perchloroethylene (Perc) from Dry Cleaning Operations (Dry Cleaning ATCM), sets forth the equipment, operations and maintenance, record keeping, and reporting requirements for dry cleaning operations. Section 93110, the Environmental Training Program for Perchloroethylene Dry Cleaning Operations (Environmental Training Regulation), sets forth the criteria for ARB to approve persons or organizations to provide the training programs for the ATCM.

The Dry Cleaning ATCM and the Environmental Training Regulation became State law in 1994. As required in Health and Safety Code Section 39666(d), the air pollution control and air quality management districts (air districts) implement and enforce the ATCMs adopted by the Board once they became State law. The air districts also had the option to adopt a regulation that is at least as stringent as an ATCM adopted by the Board. The Dry Cleaning ATCM was amended effective in late 2007. More information regarding the Dry Cleaning ATCM and the amendment is available on the Dry Cleaning Program web page.


The Curriculum for the Environmental Training Program for Perchloroethylene Dry Cleaning Operations was designed to help dry cleaners understand and comply with the Dry Cleaning ATCM and other regulations that affect the dry cleaning industry. Complying with these requirements allows dry cleaners to operate their facilities more efficiently; thereby reducing costs, Perc emissions to the air, and worker exposure to Perc. The course is also intended to provide dry cleaners with information on other regulations from agencies involved with water, worker exposure, emergency response and hazardous waste disposal.


ARB compiles a current list of individuals and organizations certified to conduct the training courses. The Certified Dry Cleaning Instructors list contains the names, email addresses, and phone numbers of certified instructors, as well as the region they cover, and the language (English or Korean) of the courses they conduct. See the Curriculum for more details.

Each facility is required to have one or more trained operators present at all times. According to the regulation it is an employee who has successfully completed the initial environmental training course to become a trained operator. Each trained operator is required to successfully complete the refresher course at least once every three years. If a trained operator leaves a facility, the facility must: (1) notify the air district within 30 days of departure of the trained operator: (2) obtain certification for a replacement trained operator within 3 months, or 1 month after the air district determines the course is reasonably available.
