2015-16078. Approval and Promulgation of Implementation Plans; Mississippi; Memphis, TN-AR-MS Emissions Inventory for the 2008 8-Hour Ozone Standard

AGENCY:

Environmental Protection Agency.

ACTION:

Proposed rule.

SUMMARY:

The Environmental Protection Agency (EPA) is proposing to approve the portion of the state implementation plan revision submitted by the State of Mississippi, through the Mississippi Department of Environmental Quality, on January 14, 2015, that addresses the base year emissions inventory requirements for the State's portion of the Memphis, Tennessee-Mississippi-Arkansas (Memphis, TN-AR-MS) 2008 8-hour ozone national ambient air quality standards (NAAQS) nonattainment area. A base year emissions inventory is required for all ozone nonattainment areas. The Memphis 2008 8-hour ozone NAAQS marginal nonattainment area is comprised of Shelby County in Tennessee, Crittenden County in Arkansas, and a portion of DeSoto County in Mississippi. EPA will take action on the emissions inventories for the Tennessee and Arkansas portions of the Area in separate actions. In the Final Rules section of this Federal Register, EPA is approving the State's implementation plan revision as a direct final rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule.

Written comments must be received on or before August 3, 2015.
