Denver (AP) - Several conservation groups are asking to intervene on the state's behalf in a lawsuit challenging Colorado's new oil and gas regulations.
Seven groups filed a motion Wednesday in Denver District Court saying overturning the new rules would endanger the state's air and water quality, hunting and fishing and the economy.
The Colorado Oil and Gas Association, a trade group, filed a lawsuit seeking to throw out the rules. The rules require regulators to give more consideration to the environment, wildlife and public health and safety when approving oil and gas development.
The rules took effect in most places in April after more than 18 months of meetings and deliberations by regulators, oil and gas officials, environmentalists, landowners and others. State and federal officials are negotiating enforcement on federal land.
