Reactivity Program

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.

November 3, 2009 -- Public Hearing: Amendments to Tables of MIR Values
The ARB will hold an Executive Officer hearing to consider amendments to the Tables of MIR Values, at Cal/EPA's Sierra Conference Room, 1001 I Street, Sacramento. The hearing will start at 9 AM. Staff proposes to revise the table of Maximum Incremental Reactivity (MIR) values for existing reactive organic compounds, and add new compounds with MIR values associated, into section 94700 of title 17, California Code of Regulations (CCR). Staff also proposes to modify MIR values for bins of hydrocarbon solvents, in section 94701 of title 17, CCR.

August 4, 2009 -- Public Workshop on Adoption of New MIR Values
The ARB will hold a workshop to discuss proposed amendments to tables of MIR (reactivity) values for VOCs, at ARB’s Monitoring & Laboratory Division building, 1927 13 Street Sacramento. Workshop and teleconference details are at the following web address: http://www.arb.ca.gov/consprod/regact/tscpwg/tscpwg.htmStaff presentation:

VOC Candidates for current research project
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.
