environmentally preferable over Alternative C.

Decision

TVA has decided to implement the preferred alternative identified in the Final EIS, Alternative B—Permanent Modifications of Dam Structures: Combination of Concrete Floodwalls and Earthen Embankments. This alternative was selected over Alternative C—Permanent Modification of Dam Structures: All Concrete Floodwalls because of the reduced long-term impacts and slightly lower construction costs. Alternative B also eliminates the need for gap closure barriers between floodwall segments.
Mitigation Measures

TVA would use appropriate best management practices during all phases of construction and maintenance associated with the proposed action. TVA would also establish the necessary traffic controls such as use of warning signs, flagmen, and lane closures during construction and maintenance activities in order to minimize traffic and safety impacts. In order to minimize impacts to potential habitat for the endangered Indiana bat, TVA would comply with the terms of the Memorandum of Agreement with the U.S. Fish and Wildlife Service. These terms include delaying the removal of suitable roost trees where feasible until after July 31, surveying for the presence of the bats before removing suitable roost trees prior to July 31, and the mitigation payment of $13,986 to the Indiana Bat Conservation Fund.

Dated: July 2, 2013. John J. McCormick, Jr., Senior Vice President, River Operations & Renewables.

**SUPPLEMENTARY INFORMATION :**  The purpose of this teleconference is to assist the FAA in its development of guidelines for the safety of occupants of commercial suborbital and orbital spacecraft. On July 31, 2013, the FAA submitted to COMSTAC a draft document on Established Practices for Human Space Flight Occupant Safety for its review and comment. The document is intended to continue the conversation that we have had with COMSTAC on commercial human space flight occupant safety. The document provides what we believe are occupant safety measures that have historically proven to be worth doing for most human space flight system concepts. We plan to submit to COMSTAC a companion document in mid-September that will provide rationale for each established practice in the draft. In this teleconference the FAA will introduce these two documents, entertain early feedback from COMSTAC members, and discuss a way ahead.

Interested members of the public may submit relevant written statements for COMSTAC members to consider under the advisory process. Statements may concern the issues and agenda items mentioned above or additional issues that may be relevant for the U.S. commercial space transportation industry. Interested parties wishing to submit written statements should contact Paul Eckert, Designated Federal Officer (the person listed in the **FOR**
