Air Plan Approval; Mississippi; Revision of Excess Emissions Provisions
The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the Mississippi Department of Environmental Quality (MDEQ) on November 17, 2016, on behalf of the State of Mississippi. The revision was submitted in response to EPA's SIP call published on June 12, 2015, concerning excess emissions during startup, shutdown, and malfunction (SSM) events. The submittal requests the revision of provisions identified in the 2015 SIP call for the Mississippi SIP. EPA is proposing approval of the SIP revision and proposing to determine that such SIP revision corrects the deficiencies identified in the June 12, 2015, SIP call.
