Fort Collins is now the second Front Range city to continue a legal battle over hydraulic fracturing. The Northern Colorado city was one of three municipalities that had their measures on the practice thrown out in court.

Homeowners and landowners have long expressed concerns about how the fracking process impacts water quality. Colorado regulations require water testing with a half mile of where a well is drilled. The samples are taken before and after the activity.

But what happens if water quality changes over time?

Flaring – the practice of burning natural gas, often when it's produced as a byproduct of oil drilling – has come under scrutiny in recent years. In part this is because new oil plays are resulting in a lot of gas being flared off.

A new map released by the group SkyTruth uses U.S. satellite data to show flaring in the United States You can see flaring between March and August 2014, and zoom in and out to see flaring in specific locations.

A scientist monitoring earthquakes near a Weld County wastewater injection well said the tremors have decreased significantly in both number and intensity.

"Seismicity has been very low," since the well – which had been shut down for 20 days – was reopened, said Anne Sheehan, a geophysics professor at the University of Colorado Boulder.

A judge has ruled that a voter approved moratorium on fracking in Fort Collins violates state law.

The Colorado Oil and Gas Conservation Commission is dropping a lawsuit it filed against the city of Longmont and its oil and gas regulations, it announced Thursday.

At a hastily organized news conference, Gov. John Hickenlooper called on all groups promoting oil and gas ballot issues to drop their proposals. To solve Colorado’s growing conflicts between development and land use, Hickenlooper proposed an 18-person blue ribbon commission composed of residents, local officials, oil and gas industry representatives as well as “respected Coloradans.”

When the city of Longmont's fracking ban was struck down by a Boulder judge, it could have been seen as a setback for those seeking to assert local control over surging oil and gas development along Colorado's populous Front Range.

A longer view of the matter, though, shows that local communities all across the state have exerted control over oil and gas within their boundaries for decades.

The Colorado Oil and Gas Conservation Commission is requiring operators of a Weld County injection well to alter how wastewater is disposed of in that well, saying they believe the well may be linked to recent earthquakes in the area.

About a month ago, the Associated Press broke the news that four in 10 new "high-risk" oil and gas wells on public lands went uninspected from 2009 to 2012.

In Colorado at least, the agency in charge of such inspections says it has been able to improve that record in 2013, following a critical report by the Government Accountability Office [pdf].
