Air and Radiation Docket and Information Center, Environmental Protection Agency, Mail Code: 2822T, 1200 Pennsylvania Ave., NW, Washington, DC, 20460 carbonpollutioninput@epa.gov Docket ID: EPA-HQ-OAR-2013-0495 & RE: EPA-R09-OAR-2013-0009 Dear EPA, My name is __________________, I have lived in Arizona since ___________ and I am concerned about the EPA’s proposed rules regarding carbon regulations in areas surrounding the Navajo Generating Station in northern Arizona, and other coal fired power plants in Arizona. The Clean Air Act gives both EPA and states a role in reducing air pollution from power plants that are already in operation. The law directs EPA to establish guidelines, which states use to design their own programs to reduce emissions. We object to the Carbon regulation proposed for existing coal fired power plant that does not take into account the costs involved in different geographies. AZ has no oil wells to pump CO2 into which makes it unfeasible in the state. AZ has no natural gas supplies and new carbon regulations that force the replacement of coal with Natural Gas plants only work in states that have Natural Gas. AZ has no such option. The States implementation plan is the best solution for long term transition to less carbon, and the 10th Amendment requires the EPA to use the State Plan in these regulations. We are opposed to the stacking of regulations on power plants that force them to close, switch to Natural Gas or join a Carbon CAP and TAX marketplace like the one in California or REGI. Because the EPA's proposed rules are unworkable on several levels at NGS, we urge the EPA to adopt the TWG BART Proposal as the final rule for NGS. We also urge the EPA to give exclusions to the rules that damage tribal and state economies. We have no Gas no Oil no choice in AZ. Sincerely, Taxpayer from AZ
