CHEYENNE - U.S. Rep. Cynthia Lummis of Wyoming on Wednesday voted against a federal proposal that included limits on further oil and gas leasing in the Wyoming Range and protection of the Snake River headwaters.

The House of Representatives on Wednesday defeated the "Omnibus Public Lands Management Act of 2009."

The bill would have set aside more than 2 million acres in nine states as protected wilderness. The Senate passed the measure in January.

In Wyoming, the bill would have prevented oil and gas drilling on 1.2 million acres within Bridger-Teton National Forest. It would have protected existing leases, but allowed remaining leases to be purchased by conservation groups so they could be retired.

Sen. John Barrasso of Wyoming introduced the Wyoming Range Legacy Act of 2007, taking up the cause from former Sen. Craig Thomas of Wyoming, who died that year.

Lummis said the omnibus bill would have cost Wyoming taxpayers and restricted millions of acres of federal lands. She said she would support the Wyoming Range bill with revisions to base boundary lines on topography and with temporary, instead of permanent, drilling restrictions.

"Folks in Wyoming need to understand this was not an up or down vote on the Wyoming Range Legacy Act or the Snake River Wild and Scenic bill," Lummis said in a release.
