Members of Colorado's Oil and Gas Association are voicing concern over some new regulations in Colorado, that could limit their operations.

From Greeley to Denver, and even Grand Junction, their message was the same.

"Please don't rule us out." That's the clear message hundreds of people across the state are pleading for Governor Ritter and his administration to hear.

Oil and gas industry leaders, employees and contractors gathered to voice their concerns over the rewrite of rules that govern the natural gas and oil industry.

"If these regulations come out like this, this could cripple this industry here in Las Animas county," says Jay Still, Pioneer Resource.

The long list of new regulations includes shutting down operations during winter months to save the wildlife population.

In order to avoid that, Still says his company, Pioneer Resource, has spent three million dollars over the past three years, looking for ways to keep their operations from impacting wildlife.

Landowner Tracy Dahl showed up to protest against this rally.

"To say 'don't rule us out' is absurd. I mean, these companies are here to stay, and the rules and regulations are just meant to produce some more protections for the environment and people."

The Department of Natural Resources will develop and present the rules to the Conservation Commission at the end of the month.
