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.”

Colorado reports 90 cases of Cyclospora this year: Here’s what health officials want you to know
As health officials investigate a growing multistate Cyclospora outbreak, Colorado public health leaders say there is no evidence of an increased risk from produce sold in Colorado.
The Colorado Department of Public Health and Environment (CDPHE) has recorded about 90 Cyclospora cases so far this year, according to State Epidemiologist Dr. Rachel Herlihy.
“We typically annually see about 167 cases of this infection in the state,” Herlihy said. “We do typically see more infections due to Cyclospora in the spring and summertime.”
Cyclospora is a parasite that causes an intestinal infection known as cyclosporiasis. Symptoms typically begin about a week after exposure and commonly include watery diarrhea, stomach cramps and nausea.
“It is not pleasant, that’s for sure,” Herlihy said. “But we don’t see high hospitalization rates associated with this particular infection.”
The parasite is most often spread through contaminated food or water. Produce such as leafy greens, herbs and berries has been linked to previous outbreaks.
“This particular parasite can be difficult to wash off of produce,” Herlihy said. “It can stay attached to greens or herbs or berries, even after you wash them.”
The warning comes as federal investigators work to identify the source of a growing outbreak affecting several Midwestern states. While the CDC’s public dashboard currently lists only 1 to 10 Colorado cases, Herlihy said those numbers are outdated because they only include reports through the middle of June.
“The outbreak that is occurring outside of Colorado really appears to have started to increase significantly in late June,” she said. “We certainly expect the CDC numbers to go up because the state health department numbers that are not yet reported on the CDC website are much higher.”
Reba Pousma, who lives in the Denver area, has been suffering from symptoms like the parasite for a week. A doctor she spoke with believes Cyclospora could be the cause of her illness, though her source of exposure has not been confirmed.
“It’s definitely different from regular food poisoning,” Pousma said. “I wouldn’t wish this on my worst enemy.”
She believes her symptoms started after eating a salad last week. She’s still battling stomach cramps, exhaustion and relentless trips to the bathroom.
“I’m on day five now of going to the bathroom over 40 times a day, and nothing has been solid,” she said.
She posted about her experience online, and the video has drawn thousands of comments, many from people who say they’re experiencing similar symptoms.
“There’s a lot of people commenting that they’re experiencing the same symptoms,” Pousma said. “I think some people are worried, and some people are like, ‘Oh my gosh, this is me too. Thankfully, somebody’s talking about it.’”
Unlike the Midwest outbreak, Herlihy said most Colorado cases reported so far this year have been linked to international travel, not food purchased or consumed in Colorado.
When someone tests positive, CDPHE investigators conduct detailed interviews about where they traveled, what they ate, restaurants they visited and grocery stores where they shopped to help identify possible sources of exposure.
Testing for Cyclospora requires a stool sample, typically using a PCR test that detects the parasite’s DNA.
Most people recover without treatment, but Herlihy said symptoms can linger for weeks and may come and go. Antibiotics can shorten the illness, particularly for people at higher risk, including young children, older adults and those with weakened immune systems.
For now, CDPHE says Coloradans don’t need to avoid fresh produce but should continue to follow safe food-handling practices by washing produce under cold water, washing their hands before and after handling food, scrubbing firm fruits and vegetables when possible, and refrigerating cut or cooked produce promptly.
“There is no reason to believe that there’s any increased risk of exposure to Cyclospora from eating produce in Colorado,” Herlihy said. “But it is always a good idea to thoroughly wash produce.”

Body found in western Colorado believed to have been eaten by bear
An investigation is underway after authorities found a body near a picnic area in western Colorado last weekend that appears to have been eaten by a bear.
The Mesa County Sheriff’s Office says the human remains were located on Sunday near the Wild Rose Picnic Area off Lands End Road on the Grand Mesa. Investigators say the remains were scavenged and scattered, and they believe the person was consumed by a bear and other wildlife.
The Mesa County Coroner’s Office is working to identify the person and officially determine their cause of death.
The sheriff’s office is asking anyone who was in the area of the Wild Rose Campground between June 22 and July 5, 2026, and noticed anything suspicious to contact Investigator Jenna Reed at (970) 244-3274.
They added that Colorado Parks and Wildlife believes there is no threat to the community at this time.
The area is home to black bears, and the MCSO shared several guidelines for the community to prevent human-bear conflicts:
- Stay alert and together: Go with others when possible, keep children in sight and close by, and avoid using headphones so you can hear your surroundings.
- Food safety: Double-bag food, pack out all food and trash, and don’t burn scraps and trash in fire rings/grills or leave them behind.
- Pet safety: Keep dogs on a leash at all times or leave them at home; don’t force a bear to defend itself.
- Camping safety: Set up camps away from dense cover or natural food sources and do not cook or store food near/in a tent. Secure food in bear-resistant containers or suspend at least 10 feet above the ground and 10 feet away from any part of the tree.
- Know how to respond: Don’t approach bears; quietly move away. Never run, as it may trigger a chase response. If a bear approaches, stand your ground, wave your arms, and yell until it leaves. Stay with your group, use bear spray, and fight back aggressively if necessary.
- Bear spray: Carry bear spray and know how to use it correctly. It’s not repellent; don’t spray your tent, campsite, or belongings.

United Way of Southern Colorado raises over $400,000 for Aspen Acres Fire victims:
Damage assessments are still ongoing for homes and businesses affected by the Aspen Acres Fire in southern Colorado, but over 200 homes have been confirmed destroyed so far. The United Way of Southern Colorado is working to raise relief funds for those affected and says it’s making progress towards its fundraising goal.
In an update on Wednesday afternoon, Pueblo County Sheriff David Lucero said they’ve assessed approximately 67% of the properties affected in the county. Authorities have confirmed the loss of 192 homes and four commercial structures so far and are working to contact property owners as quickly as possible.
Lucero urged everyone affected by the fire to use the survivor portal for more information on assistance.
Custer County Sheriff Rich Smith says they’ve lost approximately 83 homes so far, almost 2% of the county’s homes. The worst hit area is along the Highway 165 corridor, Smith added. He said that authorities don’t expect any new evacuation areas, but are not yet ready to release the existing evacuation orders.
Smith said a hotline is available during business hours for affected Custer County Residents to ask questions. He urged residents to contact them at (719) 467-0271 and advised they may need to leave a voicemail if the line is busy due to the high number of calls.
A flash flood watch is in effect for areas near the burn scar, which could affect nearby homes.
The President of the United Way of Southern Colorado, Shanna Farmer, said the organization is working to raise wildfire relief funds for those affected. Over the last few days, they have reached just over $417,000 of their $10 million goal.
“It has been incredible, the number of individuals and companies who have come out to support, to provide matches, and to provide innovative ways to raise those funds,” said Farmer. “And so, I encourage anyone who is willing to work with us on a corporate, business, or individual level to please reach out because it is going to take all of us to help rebuild.”
Farmer said that the community not only needs help with their immediate needs but also long-term support. She urged anyone interested in donating to visit their website.
The Pueblo County Sheriff’s Office says anyone who has evacuated needs to contact the Disaster Assistance Center located at 29 Lehigh Ave. in Pueblo. The center is open between 9 a.m and 6 p.m. and provides multiple resources for those forced to evacuate.
Residents must also visit the center to obtain a re-entry pass, which will allow them to return home once evacuation orders have been lifted. A photo ID and proof of residency are required. Visitors can sign up online to reserve a place in line for faster service.
