- Yavapai-Apache Nation's Comments to Advanced Notice of Proposed Rulemaking - Assessment of Anticipated Visibility Improvements at Surrounding Class I Areas and Cost Effectiveness of Best Available Retrofit Technology for the Four Comers Power Plant and Navajo Generating Station

Dear Ms. Yoshii:

As the Chairman ofthe Yavapai-Apache Nation ofArizona (Nation), please accept these comments on behalf of the Nation with regard to the U.S. Environmental Protection Agency's (EPA) Advanced Notice of Proposed Rulemaking (ANPR) on the Assessment of Anticipated Visibility Improvements at Surrounding Class I Areas and Cost Effectiveness ofBest Available Retrofit Technology (BART) for the Four Comers Power Plant and Navajo Generating Station (NGS) - Docket No. EPA-R09-0AR-2009-0598.
The Yavapai-Apache Nation is deeply concerned about the potential effects of this rulemaking on the Nation's ability to use its Central Arizona Project (CAP) water for tribal homeland purposes on the Yavapai-Apache Reservation (Reservation), and to achieve a final Indian water rights settlement for the Nation in the near future.
The Nation has a contract with the Secretary ofInterior dated December 11, 1980, for the delivery of 1,200 acre-feet of CAP water to the Yavapai-Apache Reservation located in northcentral Arizona near the towns ofCamp Verde and Clarkdale. Presently, the Nation is engaged in the development ofthe infrastructure necessary to deliver its 1,200 acre-feet ofCAP water to the Reservation.

As you know, the CAP requires power to operate the pumps and a canal system to deliver the CAP water from the Colorado River throughout Arizona. This power is supplied by the Navajo Generating Station by virtue ofthe United States' 24% ownership stake in the NGS for this very purpose. The pumping energy charges for CAP are already expensive, at $49 per acre foot for 2012 delivery rates, plus the additional operation, maintenance and replacement ("OM&R") charge which is set at $73 per acre foot for 2012 delivery rates, making for a total delivery charge of $122 per acre foot for 2012. These rates continue to increase from year to year. As such, the Nation is concerned that requiring an expensive retrofit oftechnology for the NGS will result in a substantial increase in the cost to the Nation for delivery ofits CAP water. Furthermore, the Nation is concerned that ifthe retrofit is mandated, the NGS owners will decide to shut the NGS down, which would require finding an alternative energy source likely to cost a whole lot more than the current operating cost ofthe NGS. In the Arizona Water Rights Settlement Act of 2004 (AWSA), Congress established a portion of the Lower Colorado River Basin Development Fund (LCBDF), pursuant to the Colorado River Basin Project Act of 1968, as a funding supply for future Indian water rights settlements in Arizona, as well as for defraying the OM&R charges for Indian CAP water. Revenues from the NGS, which contribute to the LCBDF, are vital to the Nation to help defray the annual OM&R charges for the Nation's 1,200 acre-feet ofCAP water, as well as helping to defray the costs of the Nation's water rights settlement. Reductions in NGS revenues to the LCBDF would jeopardize these goals for the LCBDF which were established by Congress in the AWSA.

While the Nation generally supports federal efforts to reduce pollution at the NGS, these efforts must be undertaken in consultation with, and with due consideration given to affected tribal governments such as the Nation. 

### See Executive Order 13175, 

### Consultation and Coordination with Tribal Governments dated November 6, 2000 ("Executive Order 13175"), as further effectuated in 

### EPA Region 9 

### Approach to Consultation with Tribal Governments Regarding Non-Enforcement Related Matters ("Region 9 Consultation").

The Nation requests that EPA engage in meaningful consultation with the Nation, as the actions contemplated by the ANPR could have a significant impact upon the Nation and its ability to achieve a water rights settlement and to provide its Tribal Members with adequate and affordable water for the future.
