Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is proposing to approve a portion of a revision to the Louisiana State Implementation Plan (SIP) submitted by the State of Louisiana through the Louisiana Department of Environmental Quality (LDEQ) on February 10, 2017, that addresses regional haze requirements for the first planning period. LDEQ submitted this SIP revision to address deficiencies identified by the EPA in a previous action. The EPA is proposing to approve the majority of the SIP revision, which addresses the CAA requirement that certain categories of existing major stationary sources built between 1962 and 1977 procure and install the Best Available Retrofit Technology (BART), while deferring action on LDEQ's BART determination for a single facility. Specifically, the EPA is proposing to approve most of LDEQ's BART evaluations and conclusions for Louisiana's BART-eligible electric generating unit (EGU) sources and to approve LDEQ's sulfur-dioxide (SO<INF>2</INF>) and particulate-matter (PM) emission limits for those sources that are subject to BART. The EPA is also proposing to approve Louisiana's reliance on the Cross-State Air Pollution Rule (CSAPR) trading program for ozone-season nitrogen oxides (NO<INF>X</INF>) as a permissible alternative to source-specific NO<INF>X</INF> BART emission limits. This action is being taken under sections 110 and 169A of the CAA.
