Denver, CO
Clock is ticking to clean the Front Range’s dirty air by 2027. The region’s off to a bad start this summer.
Colorado has three years to lower ground-level ozone pollution to meet federal standards, and this summer’s hazy skies — caused by oil and gas drilling, heavy vehicle traffic and wildfire smoke — are putting the state in a hole as it’s already logged more dirty air days than in all of 2023.
“Our state has taken a lot of steps to improve air quality, but you can see it in the skies, you can see it in the air, that we still have work to do,” said Kirsten Schatz, clean air advocate for the Colorado Public Interest Research Group.
Two months into the 2024 summer ozone season, the Front Range already has recorded more high ozone days than the entire summer of 2023. As of Monday, which is the most recent data available, ozone levels had exceeded federal air quality standards on 28 days. At the same point in 2023, there had been 27 high-ozone days.
The summer ozone season runs from June 1 to Aug. 31. However, the region encompassing metro Denver and the northern Front Range this year recorded its first high ozone day in May, and in some years ozone pollution exceeds federal standards into mid-September.
The region is failing to meet two air quality standards set by the Environmental Protection Agency.
The first benchmark is to lower average ozone pollution to a 2008 standard of 75 parts per billion. The northern Front Range is in what’s called “severe non-attainment” for that number, meaning motorists must use a more expensive blend of gasoline during the summer and more businesses must apply for federal permits that regulate how much pollution they spill into the air.
The second benchmark requires the region to lower its average ozone pollution to a 2015 standard of 70 parts per billion, considered the most acceptable level of air pollution for human health. In July, the EPA downgraded the northern Front Range to be in serious violation of that standard as the region’s ozone level now sits at 81 parts per billion. The state must now submit to the EPA a new plan for lowering emissions.
Colorado needs to meet both EPA benchmarks by 2027, or it will be downgraded again and face more federal regulation.
Of the 28 days the state has recorded high ozone pollution levels, 17 exceeded the 2008 standard of 70 parts per billion, according to data compiled by the Regional Air Quality Council, an organization that advises the state on how to reduce air pollution.
That’s bad news for the region after state air regulators predicted Colorado would be able to meet that standard by the 2027 deadline. The EPA calculates average ozone pollution levels on a three-year average, so this summer’s bad numbers will drag down the final grade.
“It’s not a good first year to have,” said Mike Silverstein, the air quality council’s executive director.
Smoke from wildfires near and far
Ground-level ozone pollution forms on hot summer days when volatile organic compounds and nitrogen oxides react in the sunlight. Those compounds and gases are released by oil and gas wells and refineries, automobiles on the road, fumes from paint and other industrial chemicals, and gas-powered lawn and garden equipment.
It forms a smog that can cause the skies to become brown or hazy, and it is harmful to people, especially those with lung and heart disease, the elderly and children. Ground-level ozone is different than the ozone in the atmosphere that protects Earth from the sun’s powerful rays.
Wildfire smoke blowing from Canada and the Pacific Northwest did not help Colorado’s pollution levels in July, and then multiple fires erupted along the Front Range over the past week, creating homegrown pollution from fine particulate matter such as smoke, soot and ash. Ultimately, though, the heavy smoke days could be wiped from the calculations from 2024, but that decision will be made at a later date.
Still, June also saw multiple high ozone days, and air quality experts say much of the pollution originates at home in Colorado and cannot be blamed on outside influences.
The out-of-state wildfire smoke sent ozone levels skyrocketing the week of July 21 to 27, Silverstein said, but it’s not the reason the numbers are high. The week prior saw ozone levels above federal standards, too, and wildfire smoke had not drifted into the region.
“Pull the wildfires out and we would probably still have had high ozone,” he said.
Jeremy Nichols, senior advocate for the Center for Biological Diversity, also warned that wildfires should not be used as an excuse for the region’s air pollution.
“While the wildfires are out of our control, there is a whole bunch of air pollution we can control,” he said. “I don’t want to let that cover up the ugliness that existed here in the first place.”
Nichols blames oil and gas drilling for the region’s smog. The state is not doing enough to regulate the industry, he said.
“We actually need to recognize we are at a point where oil and gas needs to stop drilling on high ozone days,” Nichols said. “Just like we’re told to stay home on high ozone days, business as usual needs to stop. I don’t think we’ve clamped down on them and in many respects they are getting a free pass to pollute.”
Legislation that would have prevented drilling on high ozone days failed during the 2024 session.
However, the air quality council has approved two measures to reduce emissions in the oil fields and is preparing to send those to the Colorado Department of Public Health and Environment for approval.
One proposal would require drilling companies to eliminate emissions from pneumatic actuating devices, equipment driven by pressurized gas to open and close valves in pipelines, Silverstein said. Oil companies already are required to make 50% of those devices emission-free, and the federal government also is requiring them to be 100% emission-free by 2035. But Colorado’s proposal would accelerate the timeline, he said.
The second proposal would tell companies to stop performing blowdowns, which is when workers vent fumes from pipelines before beginning maintenance to clear explosive gases, when an ozone alert is issued, Silverstein said.
“There are thousands of these very small events, but these small events add up to significant activity,” he said.
Gabby Richmond, a spokeswoman for the Colorado Oil and Gas Association, said the industry supports the new regulations. She said operators also were electrifying operations where possible and voluntarily delaying operational activities on high ozone days.
“Our industry values clean air, and we are committed to pioneering innovative solutions that protect our environment and make Colorado a great place to live,” Richmond said in a statement. “As a part of this commitment, we have significantly reduced ozone-causing emissions by over 50% through technology, regulatory initiatives and voluntary measures — all in the spirit of being good neighbors in the communities where we live and work.”
“Knock down emissions where we can”
Meanwhile, people who live in metro Denver and the northern Front Range are asked to do their part, too.
When the state health department issues an ozone action alert — which is a forecast for high pollution levels — people are asked to limit driving as much as possible. They also are asked to avoid using gas-powered lawn and garden equipment until later in the day when the sun starts dropping behind the mountains and temperatures fall.
It would be easy to blame Colorado’s ozone pollution on its geography, global climate change that is raising temperatures, and pollution blowing from other countries and states, Silverstein said. But Colorado has a responsibility to do its part.
“We have 4 million people and a big oil and gas field and lots of industrial activity and all of the things related to human activity all in one concentrated location with a great mountain backdrop, but it comes with a bit of a price,” he said. “So it’s up to us to find the strategies to knock down emissions where we can.”

Victor Marx wins GOP primary for Colorado governor, defeating veteran lawmaker after unorthodox campaign
Victor Marx, a first-time candidate and nonprofit leader with a controversial personal history that’s drawn intense scrutiny, has edged out his more establishment opponent and will be Colorado Republicans’ gubernatorial nominee in November.
The Associated Press called the race for Marx late Thursday afternoon, nearly nine days after polls closed. He led the runner-up, state Sen. Barb Kirkmeyer, 39.9% to 39.4%, with 99% of ballots counted, according to the AP.
Marx had taken his first narrow lead over Kirkmeyer the day after the June 30 primary, and though the race remained close, he never lost the advantage. While outstanding deficient and overseas ballots helped delay a final call on the race, those votes only served to expand Marx’s margin. He led by 2,524 votes at 5:30 p.m. Thursday, out of about 522,000 ballots cast.
State Rep. Scott Bottoms was a distant third, with 20.8% of the vote.
A veteran lawmaker and former Weld County commissioner, Kirkmeyer had jumped to an early advantage on the strength of early ballot returns. But as votes returned on Election Day began to filter in, her lead thinned and collapsed. Within 48 hours of polls closing, and with few ballots left to count in Kirkmeyer’s Front Range strongholds, her path to retake the lead had all but vanished.
Marx will next face Democratic Attorney General Phil Weiser in November. No Republican has been elected to the governor’s office in more than 20 years. Four months out, Weiser appears to be heavily favored to continue Democrats’ electoral dominance.
In an email to supporters after the race was called, Marx said he was humbled to be the nominee and that the victory was “the starting line.”
“My team and I have put together this special message that I want every Coloradan to hear — Republicans, independents, unaffiliated voters, and Democrats who are open to a better way,” he said. “Because what we’re building now is bigger than a primary victory.”
In a video, he appealed to Coloradans who are frustrated with the status quo and don’t think things can change — citing his victory as proof they can.
“Now Phil Weiser, he’s a smart fella — but he represents the current system, because he is part of it,” Marx said. “And that current system has made Colorado more expensive, less safe and harder for regular families to trust government.”
In a separate statement, Kirkmeyer said she was proud of the race that she had run and the “clear vision” she had laid out for the Republican Party here.
“While we came up short in what appears to be the closest Republican gubernatorial primary in Colorado history, I’m grateful for every voter who placed their trust in us,” she wrote.
Echoing the pledge she’d made before Election Day, she pointedly did not endorse Marx. She said only that she hoped voters “choose the path that is best for Colorado” in November.
Kirkmeyer also threw a final jab at Marx, who declined in late May to tell 9News how many people he’d killed as an adult.
Kirkmeyer wrote that, “for the record, I still haven’t killed anyone.”
First-time candidate shrugged off questions
Marx’s primary win is a remarkable result for the embattled Colorado GOP and for Marx, a former Marine, martial arts instructor and nonprofit leader whose extensive and much-scrutinized personal history had drawn national headlines. It’s also attracted sharp criticism from other Republicans.
In his video, Marx appealed to Republican primary voters, saying there was room in his campaign for those who supported his opponents.
Marx had entered the fray last fall with no political profile and no experience as a political candidate. But by the time voters began receiving ballots last month, he’d ridden an atypical — if thoroughly modern — campaign to fundraising dominance and front-runner status.
Kirkmeyer’s support largely flowed from northern Front Range counties, nudging her ahead initially. But Marx picked up bigger margins among Election Day voters — meaning those more conservative voters skeptical of mail-in balloting.
He also won ruby-red El Paso County while racking up smaller wins in rural counties and grabbing enough in the Front Range to edge Kirkmeyer.
Map: Where did the votes come from in the Colorado primary races for governor?
In a pitch reminiscent of President Donald Trump, the arch-dealmaker, Marx has cast himself as a solutions-focused negotiator disinterested in partisan squabbles. In 2003, he founded All Things Possible Ministries, a Christian nonprofit that has provided stuffed animals and trauma support to people. It has also done work in conflict areas in Syria and Iraq, where Marx primarily worked away from the front lines as a funder and facilitator.
By 2024, the nonprofit’s annual revenue had surpassed $7.5 million, and Marx has said the group — from which he has resigned — now primarily works to help law enforcement.
Despite his outsider status, Marx was considered the likely winner in the weeks before Election Day. His narrow victory, then, came as something of a surprise, and, on election night, he speculated that Bottoms — a conservative pastor from Colorado Springs — had pulled votes from him. In El Paso County, Bottoms earned more than 20,000 votes, or 24% of the county’s Republican total.
Though Marx out-raised and out-spent both Kirkmeyer and Bottoms, it was Kirkmeyer who had been perceived as the expected nominee when she entered the race last year. Marx had never run for office before, and the stories he’s told about his life — that he’d killed a man at age 7, been involved in “high-risk humanitarian” operations across the globe and could free people from demonic possession — drew intense scrutiny and national punchlines.
But he repeatedly shrugged off questions about his background and said he stood by all that he had said and written.
Through his personality-heavy, direct-to-voter campaign, he encouraged Colorado Republicans to shrug it off, too. He spent heavily on direct mailers, which provided a boost to both his fundraising and name recognition.
Marx eschewed policy discussions and skipped nearly every debate. When he did participate in one, he spent part of the event leaning on the lectern, with his dog at his feet. Rather than deliver a closing statement, he prayed.

Campaigning his own way
Though he leaned into his outsider status, the aw-shucks appeal belied a careful campaign shaped by Marx’s emergence from a political environment forged by Trump: He skipped one debate after a moderator pressed him about his background, and he held a rally instead; his campaign later highlighted how many more people attended the rally than the debate.
His media operation was led by a former Turning Points USA staffer, and his campaign touted its social media posts’ views at Marx’s watch party last week. He was comfortable as a podcast guest, regularly released videos of himself and repeatedly assured voters that he was no politician.
Though Marx had little backing — or trust — from institutional Republican forces, the PAC that supported his campaign was established by a former senior official from Gov. Bill Owens’ administration. Marx also was endorsed by U.S. Rep. Lauren Boebert, the most nationally visible Colorado Republican.
His approach proved to be enough for Colorado Republicans to back him. But his next task will be far harder.
In November, he will face a surging Weiser, who last week dismantled U.S. Sen. Michael Bennet on his way to the Democratic nomination. Weiser proved an adept fundraiser and campaigner with statewide appeal, and he will look to lead a restless Democratic base that elected progressive candidates up and down the ballot.
In a statement Thursday, Weiser said Marx’s “views and style are far out of step with Coloradans, and his nomination for governor is a threat to our state’s values and our future.”
Republicans’ last statewide win was in a University of Colorado at-large regent’s race in 2016. The state GOP has had four elected party chairs since the last Republican gubernatorial bid in 2022, which ended with a culture war-focused Heidi Ganahl — who had won that at-large regent seat — losing by nearly 20 percentage points to Gov. Jared Polis.
Simultaneously, Marx may also have to contend with an independent candidacy from Greg Lopez, a former Republican congressman and gubernatorial candidate who is gathering signatures to make the fall ballot.

Santa Fe Drive in Denver closed this weekend for pedestrian bridge construction
If you use Santa Fe Drive as a part of your daily commute, you will notice full closures this weekend on a popular section, from Florida Avenue to Evans Avenue, for the installation of a pedestrian bridge.
Once the 370-foot pedestrian bridge is completed, it will connect the east and west portions of Denver’s Overland neighborhood. This bridge will be used by pedestrians and bicyclists.
The Denver Department of Transportation and Infrastructure says this closure is needed to keep the traveling public safe. Large cranes will be used to set the two spans in place. Each one weighs about 215,000 pounds and is 180 feet long.
Once the bridge is completed in 2027, it will create a safer connection for pedestrians and bicyclists. It will link neighborhoods to trails, transit, parks, and local businesses without requiring residents to cross heavy traffic.
“Our neighborhood is quartered by transportation routes, so having a safe pedestrian bridge that can take people from one side to the other is an amazing development that neighbors have been asking for for years,” Jenn Greiving, President, Overland Park Neighborhood Association, said.
The Santa Fe Drive closure will begin at midnight on Saturday, July 11, and end on Monday, July 13, at 5 a.m. There will be detours in place. This includes:
- Southbound Santa Fe Drive Detour: Traffic will be routed to Platte River Drive to reenter southbound Santa Fe Drive at the West Evans Avenue on-ramp.
- Northbound Santa Fe Drive Detour: Access to northbound Santa Fe Drive will be at Mississippi Avenue via South Broadway Street.
- On-Ramp Closure: The West Evans Avenue on-ramp to northbound Santa Fe Drive will close at noon on Friday, July 10, to prepare for the full weekend closure and will remain closed until 5 a.m. on Monday, July 13. Traffic will be detoured to South Broadway Street to re-enter northbound Santa Fe Drive via Mississippi Avenue.
- Off-Ramp Closure: The southbound Santa Fe Drive off-ramp to West Evans Avenue will close for the full weekend period and remain closed until Friday, Sept. 11, while crews build new sidewalks and perform other concrete work at the southwest corner of the project. Detours will be posted to West Florida Avenue, West Dartmouth Avenue or West Hampden Avenue to bypass the ramp closure
During this closure, DOTI will reopen the underpass on Iowa Avenue. This is a new ADA accessible pathway that will be available between Santa Fe Drive and Acoma Street.

Denver officers cited for separate incidents, 1 fired
DENVER (KDVR) — Two officers, one now formerly of the Denver Police Department, face multiple charges relating to separate incidents in the past two months.
According to a release, now-former Denver Police Officer Gabriel Lucero was issued a citation for third-degree assault, official misconduct and false reporting, while Officer Javon Leach was cited for reckless driving and eluding.
The incident involving Lucero reportedly occurred on May 22 just before 1 a.m. in the 500 block of 16th Street. According to a release, Lucero was involved in an assault at a business, as he allegedly assaulted a person and walked away as others continued to assault the victim.
Security guards and an off-duty officer escorted him and the group out; however, Lucero reportedly identified himself as a Denver police officer and attempted to re-enter by using his police badge.
Lucero reportedly provided a false name without any other information, and further investigation verified Lucero as the person involved. Lucero was hired in 2025 and, due to his current probationary status, was fired as of Wednesday.
The incident involving Leach occurred around 1:41 a.m. on June 21, when Leach was reportedly pulling out of a parking lot on Larimer Street, attempting to drive against traffic.
Leach reportedly refused commands to stop as he left the area. Officials said he was found just seven minutes later, traveling at high speeds northbound on Park Avenue West.
He reportedly fled a traffic stop and continued to drive away, and officials deemed Leach to be the suspect following an investigation. He was placed in an off-line assignment while the case progresses, as they are considered misdemeanors.
“The Denver Police Department’s administrative review of Leach’s incident will begin once the criminal case is adjudicated, and that process includes the Denver Department of Safety and the Office of the Independent Monitor, a civilian oversight agency,” the release said.
