AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing approval of revisions to the Alabama State Implementation Plan (SIP), submitted by the Alabama Department of Environmental Management (ADEM) on November 18, 2005. The revisions include modifications to Alabama's Volatile Organic Compounds (VOCs) rules found at Alabama Administrative Code (AAC) Chapter 335-3-1. ADEM is taking an action that was similarly approved by EPA on November 29, 2004 (69 FR 69298). The revision adds several compounds to the list of compounds excluded from the definition of VOC on the basis that they make a negligible contribution to ozone formation. This proposed action is being taken pursuant to section 110 of the Clean Air Act (CAA).
