Five Colorado cities hit a benchmark for reducing carbon monoxide in the air and now Colorado will ask the Environmental Protection Agency to release it from federal oversight for monitoring those emissions.

It would be the first time in nearly 50 years that Colorado would not be under federal oversight for carbon monoxide emissions that largely were caused by heavy rush hour traffic and cars made without catalytic converters. On Thursday, the Colorado Air Quality Control Commission voted to remove federal oversight and repeal monitoring requirements. The Environmental Protection Agency must approve the plan.

“Colorado experienced high levels of carbon monoxide pollution in the 1970s and 1980s, and this milestone shows how far we’ve come in protecting and improving air quality for all Coloradans,” commission chairman Patrick Cummins said.

In the 1970s, Colorado Springs, Denver, Greeley, Longmont and Fort Collins were plagued by high carbon monoxide emissions, mostly from automobile exhaust. Throughout the decade, the region exceeded federal standards for carbon monoxide more than 100 times with most of those violations happening during daily rush hours.

Those cities were placed under Environmental Protection Agency oversight to reduce carbon monoxide, an odorless, tasteless gas that can cause headaches, dizziness, nausea and chest pain, and can exacerbate pre-existing conditions such as heart diseases.

Colorado was able to reduce carbon monoxide in the air as more automakers installed catalytic converters in cars and trucks and by using gasoline that burned cleaner. The state also started requiring auto emissions inspections.

In 1999, the state hit the federal standard for carbon monoxide emissions but it was required to stay in compliance for 20 years. It is now 80% lower than the federal standard and has stayed that way, allowing the federal oversight to be relaxed.

But that doesn’t mean the Denver Metro area and northern Front Range are in the clear. Nor will it stop finding ways to reduce carbon monoxide pollution, which also is created by oil and gas production.

The region is still considered in severe violation of National Ambient Air Quality standards for ground-level ozone pollution and measures continue to be in place to reduce nitrogen oxides and volatile organic compounds—the two ingredients that form smog on hot summer days.

Still, commissioners found the success in reducing carbon monoxide encouraging.

“Hopefully, it will inspire us to tackle the outstanding challenges that we have,” Commissioner Elise Jones said. “We can see that it is possible to achieve them.”

Colorado star and Heisman Trophy favorite Travis Hunter says he will enter the NFL Draft

Colorado star and Heisman Trophy favorite Travis Hunter says he will enter the NFL Draft


Colorado Buffaloes two-way star Travis Hunter said Thursday he plans to declare for the 2025 NFL Draft.

“That’s definitely for sure,” Hunter, 21, told reporters when asked if he intended to declare.

A favorite to win the Heisman Trophy, Hunter plays both cornerback and receiver for the Buffaloes. He is projected by many to be selected first overall next April.

When asked about playing both offense and defense as a professional, Hunter acknowledged the rarity of doing both, saying, “It’s never been done.”

He added: “I understand that it will be a high risk, [teams] don’t want their top pick to go down too early and I know they’re going to want me to be in a couple packages. But I believe I can do it. Nobody has stopped me from doing it thus far.”

More Sports from NBC News

In 10 games for Colorado this season, Hunter has 74 receptions for 911 yards and nine touchdowns — all career bests. Defensively, Hunter has three interceptions, eight passes defended and 23 tackles.

Hunter was a highly recruited player coming out of high school. A consensus five-star prospect, he originally committed to Florida State before flipping his commitment to Jackson State — becoming the first five-star recruit to commit to an HBCU.

Hunter played for one season at Jackson State under head coach Deion Sanders, then transferred to Colorado before the 2023 season when Sanders took the head coaching job there.

Last season, Hunter averaged close to 115 plays per game, participating in offense, defense and special teams.

Sanders’s son Shedeur, who plays quarterback for Colorado, is projected to be among the first signal-callers selected in next year’s draft. Another player who could be a Heisman finalist, Sanders said Thursday that Hunter is the more deserving of the two to win the award.

“If it’s between me and him, I would want him to get it,” Shedeur Sanders said. “He does a lot of amazing things and things that haven’t been done before. I’m not a selfish guy. I know what he’s capable of, so I would rather him win.”

Soaring Past the Flyers

The Avalanche beat the Flyers 3-2 at Wells Fargo Center on Monday. Cale Makar posted his 10th-career multi-goal game and Casey Mittlestadt added a goal. Additionally, Mikko Rantanen recorded two assists and Justus Annunen made 24 saves. Following a scoreless first period, Makar opened the scoring with a wrist shot from the slot at 8:30 of the second period after receiving Nathan MacKinnon’s set-up feed. Makar thought he had his second of the game at 10:44 of the middle frame, but the goal was taken off the board due to a successful Flyers challenge for goaltender interference. However, Makar would eventually double Colorado’s lead on the power play with his eighth tally of the season at 15:08 of the middle frame with a shot from the point that deflected off a Flyers player on its way in. The Burgundy and Blue took a 3-0 lead at 8:34 of the third period when Mittelstadt dispatched the rebound created by Rantanen’s shot into the net for his seventh goal of the season. The Flyers answered with goals from Owen Tippett at 11:48 and Tyson Foerster at 13:32 to cut their deficit to one, but the Avs held on to secure their 10th victory of the season.

Utah opened the scoring with a goal by Jack McBain at 3:05 of the first period but the Capitals responded with tallies from Dylan Strome at 7:46, Nic Dowd at 7:56, and Ovechkin at 11:05. Ovechkin extended Washington’s lead to three with a goal at 5:38 of the second period before Nick Bjugstad scored for Utah at 11:44 to make it 4-2 in favor of Washington entering the third period. Ovechkin did leave the game midway through the third period with a lower-body injury and has been placed on injured reserve and ruled week-to-week. The Caps added two more goals in the third period from Brandon Duhaime at 7:30 and Aliaksei Protas at 9:56 to win 6-2.

Residents rally to save Colorado Springs library on brink of closure

Residents rally to save Colorado Springs library on brink of closure


COLORADO SPRINGS, Colo. (KKTV) – Hundreds of Colorado Springs residents showed up at the Pikes Peak Library District Board of Trustees meeting Wednesday night in a last-ditch effort to save the Rockrimmon Library.

The library is set to close December 1. This comes after the board voted to not renew the library’s lease due to financial issues.

In a statement posted on their website on November 8, the board called the decision to close Rockrimmon a difficult one.

“A library provides access to resources and materials to everyone in the community, so considering a closure goes against the grain of our hopes for PPLD. However, our District provides access to nearly 700,000 people across El Paso County. We must make decisions that sustain the entire District.”

More than 250 community members showed up to Wednesday’s board meeting to show their support for keeping the Rockrimmon location open with another 119 tuning in virtually.

Former Rockrimmon Library manager Steve Abbott said he was glad to see the turnout.

“It shows that the community will not give up and they are going to fight to keep this library open,” he said.

For most of the almost five-hour meeting, 43 speakers took turns pleading with board members to postpone the library’s closure, extend the lease another year, and reconsider their decision to close the library in the first place.

One of those who spoke before the board, Abbott said closing the library will leave a massive gap for the 30,000 people who live in the area.

“It leaves a big library desert in the Rockrimmon area,” he said. “For a child to use a library now, they’ll have to go over I-25, under I-25, over Academy, under Academy to get to a library, and it’s six miles away from where Rockrimmon was.”

Speaker and Rockrimmon resident Jennifer Walker said closing the library would also deprive the area of a much-needed community center.

“There is no YMCA, there’s nothing else,” she said. “This is where we meet other moms when we’re desperate to talk to another human being that’s not a toddler, this is where we go to work when we need a quiet space, this is where the elderly come to use the computer or to check out books.”

The fate of the Rockrimmon Library was not on the board’s agenda and those who left the meeting tell 11 News the meeting ended with no resolution.

Walker said residents are still exploring their legal options.
