After more than a century of reckless mining that created a toxic legacy of pollution, the Obama administration finally started trying to prevent even more destruction by placing a few areas, including watersheds around the Grand Canyon, off-limits.
Even those modest restrictions are apparently too much for the mining industry and the politicians the industry has bought in Washington, D.C. Utah Republican Congressman Rob Bishop wants to reverse some of the mining bans enacted during the Obama era, says the Center for Biological Diversity, citing a letter from Bishop to Sec. Agriculture Sonny Perdue. Continue reading “Will the GOP roll back Obama-era mining bans?”→
Using a vast sample of data collected in a citizen science project, researchers say they’ve been able to discern how hydropeaking affects aquatic insects that form the base of river food chains. The information could help resource managers develop alternative hydropower practices that aren’t as harmful to ecosystems, according to a new study published in the journal BioScience.
Hydropeaking refers to the practice of increasing river flows at times of peak demand, generally during the day. This study shows how abrupt water level changes affect aquatic insects in every stage of life. The research was done by scientists with the U.S. Geological Survey, Oregon State University, Utah State University and Idaho State University.

As proposed in April 2015, the the plan would have resulted in major real estate sprawl around the village of Tusayan, with up to 2,100 residential units and 3 million square feet of retail space along with hotels, a spa and conference center.
The battle over fossil fuel exploitation on public lands heated up in 2015, as environmental advocates launched an aggressive #keepitintheground campaign aimed at convincing the Obama administration to stop issuing leases and permits for oil and gas drilling. But along with the political and environmental battles, there were also some feel-good stories. Right here in Colorado, for example, two beloved tracts of land administered by the National Park Service celebrated centennials. Read more about those birthdays here.
It was a big year for public lands preservation. With Congress gridlocked on many issues, President Obama took the initiative to set aside hundreds of thousands of acres as national monuments under the Antiquities Act, including Browns Canyon, in Colorado. Read more about the creation of Browns Canyon National Monument in these Summit Voice stories, and learn more about President Obama’s use of the Antiquities Act here.

Common sense tweaks would require more monitoring as well as reclamation
FRISCO — Congress, under fierce lobbying pressure from the mining industry, may not have the political wherewithal to make meaningful changes to mining laws.
But public land agencies could tweak their regulations to reduce the chances of another event like the spill from the Gold King Mine that tainted the Animas and San Juan rivers earlier this month.
A coalition of community and environmental groups hopes to spur those changes at the Department of the Interior and Department of Agriculture with a formal petition under the Administrative Procedures Act. The petition seeks four key changes to mining rules that would go a long way toward averting future toxic spills.
The rules changes would:
Limit the lifetime of a mine permit,
Impose enforceable reclamation deadlines and groundwater monitoring requirements on mines
Require regular monitoring and inspections,
And limit the number of years that a mine can remain inactive.
Fish in the Grand Canyon show levels of mercury and selenium that exceed risk thresholds for wildlife
FRISCO — Pollution runs deep in the Colorado River, according to U.S. Geological Survey scientists who recently documented traces of mercury and selenium contamination in fish living in the Grand Canyon.
