          - 40 CFR Part 52
          - [EPA-R04-OAR-2010-0289-201018(b); FRL-9203-8]

# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Proposed rule.

# SUMMARY:

EPA is proposing to approve a revision to the Alabama State Implementation Plan (SIP) submitted by the Alabama Department of Environmental Management (ADEM) on March 3, 2010. The proposed revision would modify the definition of “volatile organic compounds” (VOCs) found at Alabama Administrative Code section 335-3-1-.02(gggg). Specifically, the revision would add two compounds (propylene carbonate and dimethyl carbonate) to the list of those excluded from the VOC definition on the basis that these compounds make a negligible contribution to tropospheric ozone formation. ADEM is seeking to update its SIP to be consistent with the federal rule finalized by EPA on January 21, 2009, which excludes these compounds from the regulatory definition of VOC. This action is being taken pursuant to Section 110 of the Clean Air Act.
