Approval and Promulgation of Implementation Plans; Louisiana; Revisions to the New Source Review State Implementation Plan; Air Permit Procedure Revisions

The Environmental Protection Agency (EPA) is proposing approval of portions of ten revisions to the Louisiana New Source Review (NSR) State Implementation Plan (SIP) submitted by the Louisiana Department of Environmental Quality (LDEQ). These revisions to the Louisiana SIP provide updates to the minor NSR and nonattainment new source review (NNSR) permit programs in Louisiana contained within the Chapter 5 Permit Procedures and Chapter 6 Regulations on Control of Emissions through the Use of Emission Reduction Credits (ERC) Banking rules as initially submitted on November 15, 1993, and the subsequent rule amendments for Air Permit Procedure revisions submitted through November 3, 2014. The EPA's final action will incorporate these rules into the federally approved SIP. The rules generally enhance the SIP and were evaluated in accordance with CAA guidelines for the EPA action on SIP submittals and general rulemaking authority. This proposed action is consistent with the requirements of section 110 of the CAA.
