Broomfield officials have certified results on a recount of Question 300, formally ending the recount process on the measure that will impose a 5-year moratorium on fracking.

The margin was slim, just 20 votes confirmed passage of the measure. One group opposed to Question 300 says the issue is “far from finished.”

“There is much more that Broomfield citizens deserve to know about this election,” said BJ Nikkel, advisor to the opposition group Broomfield Balanced Energy Coalition.

In a release, Nikkel said her group is evaluating the option of an election challenge. Earlier this week, the group filed a lawsuit against election officials taking issue with the way the election was conducted.

“We are carefully evaluating the option of filing an election challenge, and again demand that the city turn over election information that is vital to assessing the true extent of the improprieties that have occurred,” Nikkel said.

Question 300 goes into effect immediately, according to officials. Broomfield joins Boulder, Longmont, Lafayette and Fort Collins in imposing restrictions on hydraulic fracturing.

The Colorado Oil and Gas Association is currently pursuing litigation against the measures in Longmont, Lafayette and Fort Collins.
