Re: Return of Submitted Rules That Implement Titles IV and V ofthe Clean Air Act (CAA) 

Dear Ms. Treadaway, 

On November 15, 1993, November 10, 1994; May 5, 2006, December 21,2011, and November 

3, 2014, Louisiana submitted proposed revisions to the Louisiana State Implementation Plan 

(SIP). These revisions were adopted under Louisiana Administrative Code (LAC) 33:III Chapter 

5 - Permit Procedures to implement Titles IV and V of the CAA. 

We are returning the Title IV rule submittals because the Region does not have the authority to 

act upon those submittals as submitted. The EPA is also returning the Title V rules. We cannot 

act upon the Title V rules as part of a SIP revision under Title I unless they are necessary to 

implement the requirements the CAA Title I. The Enclosure lists the individual SIP revisions we 

identified as implementing the requirements ofTitles IV and V. 

If you believe the proposed Title V revisions are necessary to fulfill CAA Title I NSR SIP 

requirements, please provide us with your rationale no later than 30 days following the date of 

this letter. Such rationale must include a demonstration of how the rules are needed to ensure 

new and modified sources do not violate the control strategy and do not interfere with attainment 

and maintenance of the national ambient air quality standards. See 40 CFR 51.160(a). Also, if 

you desire that we take some other action with the Title V rules such as consideration of Title V 

submittals as program updates, please provide us with your request. 

We appreciate the opportunity to work with you and if you have any questions, please call Ms. 

Stephanie Kordzi of my staff at (214) 665-7520.
