Reactivity Program

This page last reviewed July 14, 2008


Welcome to the Air Resources Board's (ARB) reactivity home page.

Ground-level ozone is formed from a reaction involving sunlight and volatile organic compounds (VOCs). However, VOCs differ in their propensity to yield ozone. Reactivity-based VOC control regulations may be more cost-effective than traditional mass-based rules in many applications.

Through these links, we present a one-stop source for reactivity-related information and events.

Below, we present recent information regarding reactivity news and events.


May 2008 (update)
"Development of the SAPRC-07 Chemical Mechanism and Updated Ozone Reactivity Scales", a report by Dr. Bill Carter for the ARB, was finalized in September 2007. It updates the previous SAPRC-99 mechanism.
In May 2008, Dr. Carter made available a revised version of this report at http://www.cert.ucr.edu/~carter/SAPRC. This includes a new Appendix E which lists the changes made to report.

May 2008
"Methyl Formate: Environmental Assessment", a response to VOC exemption petitions, was sent by ARB to California Air Pollution Control Officers.

March 2008
"Environmental Impact Assessment of Selected Halogenated Chemicals", an ARB staff report, was finalized.
Announcement of 2007 Draft Report
Report Appendices
Public Comments
Response to Public Comments

February 2008
"Reactivity Estimates for Selected Consumer Product Compounds", a report by Dr. Bill Carter for the ARB, was finalized. This report describes the reactivities of over 40 consumer product VOCs, including several amines.

February 2008
The ""Final Reactivity Analysis Report", based on ARB's 2005 Architectural Coatings Survey, was released.

February 2008
The webpage,"Architectural Coatings Program" ,includes the Final Reactivity Analysis Report based on the 2005 Architectural Coatings Survey.

Ongoing
The webpage,"2008 Consumer Products Regulatory Work Group Activity", provides information about upcoming regulations in consumer products. These regulations involve reactivity issues.

September 2007
