A recent finding by NASA reveals that a small area in the four corners region has the highest methane gas concentration in the United States. As Arizona Public Radio’s Justin Regan reports, the study finds the main culprit is natural gas leaks from coal production.
State officials and utilities are trying to kill a plan by the U.S. Environmental Protection Agency to force owners of three coal-fired power plants to install expensive pollution control equipment to improve visibility.
A coal-fired power plant on the Navajo Nation may be forced to increase water rates to afford required federal pollution controls.
Initially the utility that runs the Navajo Generating Station thought it might have to shut down. But a new Interior Department study says it has another option. The Generating Station could remain open if it raises water rates for agricultural users and tribes by up to 16 percent.
