### 26891 Federal Register / Vol. 75, No. 92 / Thursday, May 13, 2010 / Proposed Rules

Section 106, describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the Agency’s authority.

We are issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701,

‘‘ General requirements. ’’ Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.

**Approval and Promulgation of Implementation Plans; Texas; Excess**  **Emissions During Startup, Shutdown, Maintenance, and Malfunction**  **Activities**

**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Proposed rule.

**SUMMARY :**  The EPA is proposing to partially approve and partially disapprove a revision to the Texas State Implementation Plan (SIP) submitted by the Texas Commission on Environmental Quality (TCEQ) in a letter dated January 23, 2006 (the January 23, 2006 SIP submittal). This SIP submittal concerns revisions to 30 Texas Administrative Code (TAC) Chapter 101, General Air Quality Rules, Subchapter A General Rules; and Subchapter F Emissions Events and Scheduled Maintenance, Startup, and Shutdown Activities. This action proposes approval of those portions of the rule that are consistent with the Clean Air Act (the Act), and disapproval of those portions of the rule that are inconsistent with the Act. We are proposing disapproval of provisions that provide for an affirmative defense against civil penalties for excess emissions during planned maintenance, startup, or shutdown activities. A disapproval of these provisions means that an affirmative defense is not available in the federally approved SIP for violations due to excess emissions during planned maintenance, startup, or shutdown activities. This action is in accordance with section 110 of the Act.

**DATES :**  Comments must be received on or before June 14, 2010.
