The operator of a coal-fired power plant on the Navajo Nation is asking the federal government for more time to develop ways to cut pollution.
The U.S. Environmental Protection Agency has proposed that haze-causing nitrogen oxide emissions at the Navajo Generating Station in Page be reduced by 84 percent within 10 years. The EPA says that translates to 28,500 tons a year and improved air quality at places like the Grand Canyon.
The Salt River Project says it has been working with others to come up with alternatives, but they need more time.
The EPA plans to hold a handful of public hearings before the comment period ends on Aug. 5.
An EPA spokesman said Monday that the agency hasn't decided on an extension.
