– Current license issued Oct.1963 – Expires Sept. 2013– Filed NOI/PAD September 22, 2008– Preparing license application 2008 – 2011 – File license application September, 2011– Re-licensing could affect all levels of Operations

• Lake levels• Downstream releases• Water supply yield• Water releases for instream flows and bays & estuaries• Hydroelectric power production• Construction/Permitting within Project Boundary

Re-Licensing the Toledo Bend Project

FERC Relicensing Challenges

• In the early 1960’s, the Clean Water Act, the National Environmental Protection Act, and the National Historic Properties Act had not been enacted.

• Before FERC will issue a new license for Toledo Bend, all those Acts must be complied with.

• It is the responsibility of the licensee’s (SRA-TX and SRA-LA) to prove the project is in compliance.

• Length – 560 miles

• Drainage Area – 9,952 sq. mi.25% in Louisiana75% in Texas

• Boundary reach covered by Sabine River Compact.

• Available water from the boundary reach down is split equally between States.

• Toledo Bend Dam is located 147 miles from top of Sabine Lake.

• Average Inflow into Sabine Lake – 5,982,000 Ac-ft/yr

Future Utilization of Toledo Bend Reservoir

• SRA’s Board of Commissioners has adopted the strategy of developing water sales as an alternative source of revenue in lieu of hydroelectric power generation.

• “Run of the River” for Power Generation– Environmental Flows– Controlled excess capacity releases

Water Supply Proposal

• Out-of-State Sale– Requires Governor’s Consent

Balancing Water Supply/Lake LevelSRA-LA & SRA-TX

• Inter-Basin Transfers– Present Law prohibits SRA-TX from transferring water outside

the Sabine River Basin– Highly probable SRA-TX will be granted a permit to transfer

300,000 acre-feet per year outside the Sabine River Basin of Texas

• SRA-LA will reduce its allocation to 300,000 acre-feet per year

• Proposed Cooperative Agreement– In the event SRA-TX does not receive an Interbasin Transfer

Permit, SRA-LA may enter into agreement with SRA-TX to purchase up to 300,000 acre-feet per year for lake-level mitigation and to balance operational budgets

Water Supply vs. Hydroelectric CONCLUSION

• Extensive Financial and Environmental Analysis have been conducted

• Minimal Environmental Impact and Substantial Economic and Social Benefits

• Consistent with purposes for which Toledo Bend was constructed

• Consistent with the public trust mandate of Article IX, 1 of the Louisiana Constitution
