The EPA is promulgating full approval of the Operating Permit Program submitted by the Texas Natural Resource Conservation Commission (TNRCC or Commission) based on the revisions submitted on June 12, 1998, and June 1, 2001, which satisfactorily address the program deficiencies identified in EPA's June 7, 1995, and June 25, 1996, Interim Approval (IA) Rulemakings. See 60 FR 30037 and 61 FR 32693. The TNRCC revised its program to satisfy the conditions for full approval, and EPA proposed full approval in the Federal Register on October 11, 2001 (66 FR 51895). This notice only takes action on issues related to correcting interim approval issues. We will address other issues at a later date as described in sections V.C and V.D of this document.
