It took 50 years but Colorado finally met federal standards to lower carbon monoxide pollution
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.”

2026 Rockies’ good, bad and tradeable at the season’s quarter mark
By almost every measure, the 2026 Rockies are better than the ’25 Rockies. And, by almost every measure, the Rockies have a long way to go to become a contending big-league baseball team.
After getting bludgeoned by Kyle Schwarber and shut down by ace lefty Cristopher Sanchez in a 6-0 loss at Philadelphia on Sunday, the Rockies are 16-25 with one-quarter of the season in the books.
Schwarber hit solo home runs in the first and second innings off right-hander Tomoyuki Sugano, who gave up five runs on seven hits over five innings. Sanchez dominated Colorado for seven innings, giving up six hits, striking out seven, and walking none. He reduced his ERA to 2.11.
It was a step back for Colorado, but a week ago, Paul DePodesta, president of baseball operations, said, “We’re certainly encouraged by a lot of what’s going on, but at the same time, far from satisfied.”
Here’s a look at the state of the Rockies at the quarter pole:
• On pace: The Rockies’ .390 winning percentage has them pointed toward a 63-99 record. That would be a 20-game improvement over their 119-loss season in 2025 and enable them to avoid the infamy of being the first team since the 1961-64 Washington Senators to post four consecutive 100-loss seasons.
• White Sox meter: Chicago’s Southsiders lost a major league record 121 games in 2024. At the quarter pole last year, they were a miserable 12-29, but they eventually finished with a 60-102 record. That was a 19-game improvement.
• Road conditions: Colorado was laughably bad on the road last season, going 18-63, averaging just 2.81 runs per game, and getting outscored by 213 runs. The ’26 Rockies no longer look like automatic roadkill. They are 8-14 away from Coors Field but 6-4 over their last 10 games. They are averaging 3.95 runs per game on the road.
• Rotation in motion: The ’25 Rockies finished with a starters ERA of 6.65, the worst in the majors since ERA became an official statistic in 1913. This season’s starters own a 5.27 ERA, still the worst in the majors, but an improvement. Toss out the innings thrown by “openers” and the starters’ ERA is 5.11.
• Ace in the making? Right-hander Chase Dollander, who has the pure best stuff on the staff, is exponentially better this season than last — 3.35 ERA vs. 6.98 ERA as a rookie. On Friday, he held the Phillies to two runs and three hits in 5 2/3 innings, but walked five in the Rockies’ wild, 9-7, 11-inning victory. Dollander’s command was not sharp, but he didn’t implode as he might have last season.
“Every outing is different, for everybody,” Rockies manager Warren Schaeffer told MLB.com. “Today, for Chase, he had to battle command issues, but his stuff is so good that he was able to stay in it. He competed, and he kept grinding without his best command.”
Trade material: Except for Dollander, Colorado’s four other starters are all veterans in the final year of their contracts. That makes them possible trade candidates at the Aug. 3 deadline, if not before.
However, after a strong start to the season, the starters are beginning to fade. Lefty Kyle Freeland (1-4, 6.00 ERA) has a vesting option worth $17 million for 2027, but he needs to pitch 170 innings to activate that option, and it’s doubtful he will. There is a $9 million team option for right-hander Michael Lorenzen, but considering that he is 2-4 with a 6.92 ERA and a 3.56 batting average against, it’s doubtful the Rockies would pick up his option. But are either Lorenzen or Freeland tradeable?
That leaves lefty Jose Quintana (1-2, 3.90 ERA) and Sugano (3-3, 4.07 ERA) as the most attractive trade pieces. And throw in reliever Antonio Senzatela (2-0, 1.11 ERA), too, because he’s also in the final year of his contract.
Somehow, someway, the Rockies are going to have to restock their pitching cupboard for next season and beyond. It’s a predicament that DePodesta and company will have to solve.
Men of mystery: The hope was that this would be corner outfielder Jordan Beck’s breakout season, and that centerfielder Brenton Doyle and shortstop Ezequiel Tovar would bounce back. It’s early, but it’s not happening.
After going 1 for 3 on Sunday, Beck is hitting .169 with a .490 OPS. Doyle (.196, .529, 33.6% strikeout rate) is showing signs of rebounding, as is Tovar (.197, .277, 28.6%), who had two singles on Sunday. Still, the trio is underperforming. Beck and Doyle are often supplanted in the lineup by Mickey Moniak and newcomers Troy Johnston and Jake McCarthy.

After a 1-for-4 performance on Sunday, Moniak is hitting .303 with a 1.004 OPS and leads the Rockies with 11 home runs. Moniak has had hot streaks before with the Angels, but then faded. However, the Rockies believe he can sustain his success.
He’s arbitration-eligible for one more season, leading to plenty of internet trade speculation. But if the Rockies don’t believe their outfield prospects are ready to carry the load, signing Moniak to a reasonable contract extension makes sense. He’s making $4 million this season.
First addition: Utility infielders Edouard Julien and Willi Castro, and outfielders Johnston and McCarthy have all contributed to Colorado’s improvement. But it’s rookie first baseman TJ Rumfield who looks like part of the Rockies’ foundation for the future.
He’s slashing .272/.337/.429 with five home runs and is tied with Moniak for the team lead with 21 RBIs. Among all qualified rookies, he is tied for first in games played (40), second in hits (40), fifth in RBIs (21), and eighth in batting average. He’s also a terrific fielder.
Rumfield is everything the Rockies hoped Michael Toglia would be.

Colorado man sentenced to over 40 years in prison for murder of ex-girlfriend
A Boulder County man was sentenced to 48 years in prison for murdering his ex-girlfriend and dumping her body in 2024.
The Boulder County Sheriff’s Office said Christine Barron Olivas’s body was discovered in a remote area of unincorporated Boulder County on Sept. 14, 2024. She was last seen leaving the neighborhood with her boyfriend, Carlos Dosal, the week prior.
The coroner’s office determined the cause of her death was strangulation.
In Feb. 2026, Dosal pleaded guilty to second-degree murder as a crime of domestic violence in her death. On Saturday, the judge sentenced him to 48 years in the Colorado Department of Corrections.
