The 77-20 vote on Thursday sends the bill to the House, where final legislative approval could come as early as next week.

The Senate first approved the measure in January, but the House rejected it last week amid a partisan dispute over gun rights. The gun issue was not raised during Senate debate.

The legislation is a package of nearly 170 separate bills. In Wyoming, it would limit further oil and gas leasing in the Wyoming Range, designate the Snake River headwaters as “wild and scenic” and provide federal compensation to ranchers for wolf-killed livestock.

Wyoming Sens. Mike Enzi and John Barrasso voted for the bill Thursday. Rep. Cynthia Lummis voted against the bill last week in the House and has continued to express concern about the omnibus bill.

Barrasso said he disagreed with the way the 170 bills were bundled together but felt it was important to support the Wyoming measures.

“I am proud that proposals generated by folks in Wyoming have today passed the U.S. Senate,” Barrasso said. “This is the direct result of people working together in their communities.”

The bill would prevent oil and gas drilling on 1.2 million acres of the Wyoming Range, a range on the state’s western flank within Bridger-Teton National Forest. It would protect existing leases but allow conservation groups to buy remaining leases and retire them from possible development. The energy industry, including the Petroleum Association of Wyoming, has opposed the bill.

“This collection of bills does more for hunters and anglers than any legislation in the last 25 years,” Tom Reed, Trout Unlimited field coordinator in Wyoming and Montana, said in a statement. “It protects sportsmen access to public land and some of the finest fish and wildlife habitat in the country.”

The Snake River measure would protect 387 miles of rivers and streams in the headwaters area in and surrounding Jackson Hole under the federal Wild and Scenic Rivers Act.

“For those members of the House who want to help Wyoming business owners, outfitters and our state’s tourism economy while protecting some of the most spectacular places in Wyoming, voting in favor of this bill is the way to do it,” said Tom Patricelli, executive director of Campaign for the Snake Headwaters, in a statement. “It’s time to do the right thing for Wyoming.”

The legislation would confer the government’s highest level of protection on land ranging from California’s Sierra Nevada mountain range and Oregon’s Mount Hood to Rocky Mountain National Park in Colorado and parts of the Jefferson National Forest in Virginia.

Sen. Tom Coburn, R-Okla., held up the bill’s passage last year and again this year, arguing that it was unnecessary and would block energy development on millions of acres of federal land. The bill moved forward this week after Coburn was allowed to submit six amendments for approval. Five were defeated.

A sixth provision, softening a provision to impose criminal penalties for collecting some fossilized rocks on federal land, was included in the final bill.

Because of a parliamentary maneuver adopted in the Senate, the House is expected to take up the bill under a rule that blocks amendments or other motions to derail it. Republicans used the threat of an amendment to allow loaded guns in national parks to defeat the wilderness bill last week.
