## Abstract

The Environmental Protection Agency (EPA) is approving a revision to the Alabama State Implementation Plan (SIP) submitted by the Alabama Department of Environmental Management (ADEM) on October 26, 2015. The revision modifies the definition of "volatile organic compounds" (VOC). Specifically, the revision adds three compounds to the list of those excluded from the VOC definition on the basis that these compounds make a negligible contribution to tropospheric ozone formation. This action is being taken pursuant to the Clean Air Act (CAA or Act).
