The spill from Colorado’s Gold King Mine last summer released 3 million gallons of wastewater and polluted two western rivers. A new report by the U.S. House says government workers at the mine knew a spill was possible. Arizona Public Radio’s Ryan Heinsius reports. 

    

In 2015 the EPA issued a Clean Power Plan directing states to limit carbon dioxide emissions from power plants. Under the plan, for example, Arizona will need to cut annual carbon emissions from 40 to 30 million tons by 2030.

The State of Arizona has joined a lawsuit against the U.S. Environmental Protection Agency over the federal Clean Power Plan. It’s among two dozen states fighting the new regulations that limit greenhouse gas emissions from the nation’s power plants. Arizona Public Radio’s Ryan Heinsius reports.

Waste from the Gold King Mine in Southwest Colorado continues to flow nearly two months after millions of gallons of the toxic material were released into local waterways. Now the U.S. Environmental Protection Agency has a new plan to help clean it up, by installing a water treatment system near the mouth of the mine. Arizona Public Radio’s Ryan Heinsius reports.


Earth Notes: The Four Corners’ Methane Problem

Sep 30, 2015

The San Juan River Basin has a rich human history, visible in places like the ancient pueblo ruins of Chaco Canyon. But it is different relict of a much older history, rooted late in the Age of Dinosaurs, that is drawing attention to the basin these days: methane gas.

Navajo Nation President Russell Begaye testified Wednesday before the U.S. Senate Committee on Indian Affairs about the impacts of the Gold King Mine spill on the tribe. As Arizona Public Radio’s Ryan Heinsius reports, he’s concerned about the spill’s environmental and economic impact on Navajo farmers.

President Begaye said the U.S. Environmental Protection Agency waited 48 hours before informing Navajo Nation officials of the incident. He said the agency’s response lacks transparency and creates mistrust.
