## Abstract

EPA is approving severable portions of two revisions to the Texas State Implementation Plan (SIP) submitted by the State of Texas on October 24, 2006, and August 16, 2007. These revisions amend existing sections and create a new section in Title 30 of the Texas Administrative Code (TAC), Chapter 101--General Air Quality Rules, Subchapter H--Emissions Banking and Trading, Division 4--Discrete Emission Credit Banking and Trading, referred to elsewhere in this notice as the Discrete Emission Reduction Credit (DERC) Program. The October 24, 2006, submittal creates a new section for international emission reduction provisions and amends existing sections to prohibit the generation and use of DERCs from shutdown activities and further clarify procedures for using emission protocols. The August 16, 2007, submittal amends two sections of the DERC program to update cross- references to recently recodified 30 TAC Chapter 117 provisions. Additionally, EPA finds that the Texas Commission on Environmental Quality (TCEQ) has satisfied all elements of our September 6, 2006, final conditional approval of the DERC program with the submittal of the October 24, 2006, SIP submittal; and as such, the DERC program conditional approval is converted to a full approval. EPA has determined that these SIP revisions comply with the Clean Air Act and EPA regulations, are consistent with EPA policies, and will improve air quality. This action is being taken under section 110 and parts C and D of the Federal Clean Air Act (the Act or CAA).
