The future of the Navajo Generating Station near Page, AZ. remains uncertain. The Interior Department has requested the U.S. Environmental Protection agency to put off a decision on pollution controls for the coal fired plant for at least six months.
A decision by the EPA was expected this summer which likely would have required additional reductions of nitrogen oxide emissions.
An official from the Interior Department says the office needs more time to study the impacts of requiring additional pollution controls.
The Navajo Generating Plant provides power for metropolitan areas including Phoenix. Conservationists say the pollution has far reaching effects on air quality and poses health hazards.
