The U.S. Department of Interior decided on Tuesday that the greater sage grouse does not need protection under the Endangered Species Act. The bird spans eleven western states including Colorado, where it lives in pockets along the western slope.  The population is mostly concentrated in the northwest part of the state. Governor John Hickenlooper was one of the many people working to avoid a federal listing for the bird.  He sat down with statehouse reporter Bente Birkeland to talk about the decision and other initiatives.

Interview Highlights

Land near the Colorado-New Mexico border has recently been caving inwards in an area where a 5.3 magnitude earthquake took place in 2011. As KRCC’s Dana Cronin reports, scientists at the United States Geological Survey are pointing to wastewater disposal as a potential trigger.

Higher magnitude earthquakes are a rarity in Colorado, making the 2011 quake of special interest to scientists. Research showed a possible cause as wastewater injection which involves the pumping of large volumes of fluid into the Earth, creating high-pressure conditions.

State energy regulators have dropped their lawsuit against the city of Longmont for adopting stricter oil and gas rules that Colorado officials argued infringed on the state’s rights. Bente Birkeland has more…

Meanwhile, a judge in Fort Collins today ruled that that city's ban on fracking violates state law.

Scientists Study Trinidad-Area Earthquakes

Jan 28, 2014

Scientists with the US Geologic Survey are studying the relationship between earthquakes, gas drilling and the practice of re-injecting waste-water into the ground. They're looking at area around Trinidad in Southern Colorado, where the number of earthquakes has been growing.  Trinidad currently averages about eight magnitude-3 earthquakes a year.

Geophysicist Justin Rubinstein with the USGS, says there appears to be a correlation to the waste water injection process, but  adds it happens at only a handful of the 35,000 injection wells across the country.
