OFFICE OF AIR AND RADIATION
The Honorable Jeff Flake U.S. House of Representatives Washington, D.C. 20515 Dear Congressman Flake: Thank you for your letter of February 24, 2012, to President Obama, co-signed by five of your colleagues, concerning the U.S. Environmental Protection Agency's upcoming action on the Regional Haze Federal Implementation Plan (FTP) for the Navajo Generating Station (NGS). The President has asked that I respond on his behalf. We understand your concerns and appreciate your interest in developing a viable solution. We have met with tribal stakeholders to assess their needs and issues with regard to the FTP. In addition, the EPA met with CAP to discuss the FTP and recently we met with representatives of the Maricopa-Stanfield Irrigation and Drainage District. We look forward to continuing the discussions with all interested parties. We realize the significance of the NGS facility to the Navajo, Hopi, Gila River, and other tribes, as well as many others who depend on the power from NGS for a variety of purposes. Tn a recent letter to Interior Secretary Salazar and Energy Secretary Chu, EPA Administrator Jackson affirmed her commitment to collaborate with those agencies "on creative solutions to protect the environment, human health and natural resources, while honoring tribal communities and advancing our nation's renewable energy future." A copy of her letter is enclosed. The EPA staff has been meeting periodically with representatives from the Departments of Tnterior and Energy to discuss the National Renewable Energy Laboratory report and to better understand the many issues associated with the NGS plant. I assure you we will consider the information in your letter, as well as what we learn in our continued stakeholder meetings, in developing a FTP that fully meets the requirements of the Regional Haze Rule. We expect to propose the FTP this summer; it will be open for public comment for at least 90 days and the EPA will hold several public hearings during this time. We welcome any additional information you may have for our consideration.

Working toward improving visibility in our national parks and wilderness areas, the U.S. Environmental Protection Agency is undertaking rulemaking involving the Navajo Generating Station. Situated on the northwest corner of the Navajo Nation, near Page, Ariz., the power plant and its relationship to the tribes and the Central Arizona Prolect have been part of numerous discussions among the EPA, the Dcpartrneni of the Interior and the Department of Fnergy. In the Clean Air Act, Congress mandated the goal of restoring visibility in our parks and wilderness areas to natural conditions. To achieve this goal. the EPA developed rules to implement the RegionalHaze Program and the Best Available Retrofit Technology requirement to reduce emissions of visibilityimpairing pollutants from certain stationary sources. The Navajo Generating Station is among the nations highest emitters of nitrogen oxides and is near II national parks, including Grand Canyon National Park. The National Renewable Energy Laboratory last month released a study, produced for the Department of the Interior, that describes the complexity of the economic relationships among the tribes, the plant's owners and the Central Arizona Project and examines the impacts of potential air-pollution controls. The study raises several issues that I am interested in discussing with you, including a transition from the current situation to a future that involves renewable energy development and protects the tribes' economic interests. The challenges presented by the power plant offer a unique opportunity for our agencies to collaborate on creative solutions to protect the environment, human health and natural resources, while honoring tribal communities and advancing our nation's renewable energy fl.zture. Although the EPA and the departments of' the Interior and Energy operate with different authorities, we share the federal trust responsibility to tribes and the obligation to engage in meaningful consultation. Please accept my invitation to meet at our earliest convenience to discuss a plan to address these challenges. I suggest we all ask our stafts to identif' concerns and potential solutions in advance of ourmeeting. These solutions could focus on mitigating the impacts on tribes and promoting a transition to

clean energy, as directed by President Obama. If you have any questions or concerns, please do not Lesitate to contact me or your staff may contact Jared Blumenfeld, the EPAs Region 9 Administrator, at (415) 947-8702 or bIumenfe1d.jarcdepa.gov
