[EPA-R04-0AR-201O-0289-201018(b); FRLApproval and Promulgation of Implementation Plans

Alabama: Volatile Organic Compounds

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 fonnation. 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.
