On September 25, 2013, Central Arizona Project (CAP) learned that the U. S. Environmental Protection Agency (EPA) has accepted the historic Navajo Generating Station (NGS) "Technical Work Group (TWG) BART Proposal" as an option for controlling nitrogen oxide emissions at the power plant. The alternative proposal was submitted by CAP and other stakeholders in July.

"We could not be more pleased at this point in the process," CAP General Manager David Modeer announced at the news. "The decision by EPA to include this alternative as an option to be considered means that they have concluded that our proposal would indeed meet the strict Best Available Retrofit Technology (BART) standard proposed by the EPA in February 2013."

"Now that the EPA has accepted our alternative as a viable emission control method," added CAP Board President Pam Pickard, "we are asking our customers, elected representatives and stakeholders to submit supportive comments so that EPA's ultimate decision will be to use this alternative to set their final BART rule."

EPA will accept public comments on the TWG BART Proposal and their original BART proposal through January 6, 2014. Interested parties can find information on how to submit comments to the EPA on the CAP web site at

The Better than BART alternative was developed by a Technical Work Group (TWG) composed of the Central Arizona Water Conservation District, the Environmental Defense Fund, the Gila River Indian Community, Navajo Nation, the Salt River Project Agricultural Improvement District, the Department of the Interior and Western Resource Advocates.

The Navajo Generating Station provides more than 90 percent of the power used by CAP to pump more than 500 billion gallons of Colorado River water annually to cities, farms, Native American nations and businesses in Arizona.
