Airborne Toxics Control Measures

For more information about the District’s Air Toxics program, see Air Toxics Overview

The California Air Resources Board (ARB) has promulgated Airborne Toxic Control Measures (ATCMs) for several source categories. Each ATCM is codified under Titles 13 or 17 of the California Code of Regulations and is available on the ARB website

When the state adopts an ATCM, the District can either implement the state ATCM or adopt a local rule consistent with the ATCM. The following table shows the rules the District has adopted for corresponding ATCMs.





Storage and Transfer of Gasoline Benzene Airborne Toxic Control Measure For Retail Service Stations


Control of Hexavalent Chromium in Cooling Towers Chromate Treated Cooling Towers


Control of Dioxins from Medical Waste Incinerators Dioxins Airborne Toxic Control Measure – Medical Waste Incinerators


Control of Ethylene Oxide Emissions Ethylene Oxide Airborne Toxic Control Measure for Sterilizers And Aerators

The District has elected to implement several state ATCMs directly without adopting a rule. The majority of the state ATCMs and federal NESHAPs (sometimes referred to as Maximum Achievable Control Technology or MACT) are not adopted as a District rule. For more information on ATCMs and MACTs, see this file atcm-mact.pdf or contact the Engineering Division at 961-8800 or [email protected].
