Navajo Generating Station

BETTER THAN BART

CAP and other NGS stakeholders developed an alternative "Better than BART" plan for NGS. This plan includes two alternatives that both achieve even greater emission reductions than the EPA's proposed rule. Read more



Background

Central Arizona Project (CAP) delivers and manages the single largest source of renewable water supplies in the State of Arizona from the Colorado River.  Simultaneously, CAP is the largest single end-user of power in the state. The Navajo Generating Station (NGS), located near Lake Powell on the Navajo Reservation, provides more than 90% of the power CAP needs to deliver water.

 

On February 5, 2013, the US Environmental Protection Agency (EPA) issued a proposed Best Available Retrofit Technology (BART) rule for NGS to reduce emissions of nitrogen oxides (NOx) from the plant. The result of the BART rule could cost more than 1.1 billion to install new technology and equipment at the plant. CAP's portion of these costs would be borne by its customers throughout Maricopa, Pima and Pinal counties. 

 

CAP, along with the Gila River Indian Community, the Navajo Nation, SRP, the Environmental Defense Fund, the U.S. Department of the Interior and Western Resources Advocates, created a Technical Work Group to develop an alternative "Better than BART" plan for NGS. Better than BART includes two alternatives that both achieve even greater NOx emission reductions than the EPA's proposed rule.

 

Navajo Generating Station – Kayenta Mine Complex Project Environmental Impact Statement

On behalf of the Department of the Interior, the Bureau of Reclamation (Reclamation) is the lead Federal agency, and the Office of Surface Mining Reclamation and Enforcement (OSMRE) and the Bureau of Indian Affairs (BIA), are key cooperating agencies, for the preparation of an environmental impact statement (EIS).


The purpose of the EIS is to evaluate the potential environmental impacts of extending the operation of the Navajo Generating Station (NGS), located on lands leased from the Navajo Nation, near Page, AZ. The EIS also will evaluate potential environmental impacts from continued production of coal at the Kayenta Mine, about 80 miles southeast of the NGS, near Kayenta, AZ. Kayenta Mine is located on lands leased from both the Navajo Nation and Hopi Tribe. Currently Kayenta Mine is the sole source of coal from NGS, and the NGS is Kayenta Mine’s only customer. Both the NGS and the Kayenta Mine would continue production for an additional 25 years, from 2020 through 2044.
