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.

September 3, 2010 -- Final Regulation Order: Amendments to Tables of MIR Values
On September 2, 2010, California's Office of Administrative Law (OAL) approved rulemaking for "Amendments to the Tables of Maximum Incremental Reactivity (MIR) Values”, and filed this with the Secretary of State. The rulemaking will become effective on October 2, 2010. See the final regulation order.
July 1, 2009 -- Updated MIR Reports
Report: Updated Maximum Incremental Reactivity Scale and Hydrocarbon Bin Reactivities for Regulatory Applications
Spreadsheet File: HCcalc.xls
May 2008, Methyl Formate: Environmental Assessment
A response to VOC exemption petitions, was sent by ARB to California Air Pollution Control Officers.
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, Architectural Coatings Survey Final Reactivity Analysis Report
A report based on ARB's 2005 Architectural Coatings Survey, was released.
The webpage Architectural Coatings Program includes the Final Reactivity Analysis Report based on the 2005 Architectural Coatings Survey.
Ongoing, 2008 Consumer Products Regulatory Work Group Activity
The webpage,2008 Consumer Products Regulatory Work Group Activity, provides information about upcoming regulations in consumer products.
These regulations involve reactivity issues.
September 2007, VOC Reactivity Technology Forum
The forum was held at SCAQMD Headquarters.
