EPA has revised their definition of volatile organic compounds (VOCs) for purposes of preparing state implementation plans (SIPs) to attain the national ambient air quality standard for ozone under Title I of the Clean Air Act (Act). This revision adds the compounds propylene carbonate and dimethyl carbonate to the list of compounds which are excluded from the definition of VOC on the basis that these compounds make a negligible contribution to tropospheric ozone formation.

The final rule is effective on February 20, 2009. For more information, contact William L. Johnson at (919) 541-5245.; fax number: 919-541-0824; e-mail address:
