Aurora, Colorado 2021-07-24 08:00:49 –
This summer, gray haze blurring mountain views along Colorado’s front range showed ozone every day. pollution Soaring to dangerous levels (up to 48% higher than federal health limits) and some of the most deadly air in decades.
Average ozone pollution State data reviewed by The Denver Post shows that it has increased over the past two years, interrupting improvements made since 1980.
This year, the average ozone levels at all 16 Colorado Public Health and Environment Department air quality measurement stations along the front range exceeded 72 ppb. health 70ppb limit. In 2019, only five stations showed ozone averages above their limits.
On Tuesday, ozone surged to 104 ppb in Chatfield State Park, southwest of Denver. Other spikes this week reached 103 ppb at Boulder Reservoir and 101 ppb at Golden. Beyond the city, Rocky Mountain National Park’s ozone levels reached 76 ppb on July 12.
The backslide shows that the U.S. Environmental Protection Agency announced the status of Colorado air quality offenders later this yearseriousFrom “” to “severe”.It will bring stricter restrictions industry Colorado officials said the post gas needed to be reblended into a cleaner combustion mix. The EPA estimates that it will add a few cents per gallon to the price of gasoline pumps.
CDPHE officials will issue high-ozone “Action Day” alerts for 19 consecutive days (until midnight on Friday) to warn of unhealthy conditions, urge residents to reduce driving, and fuel after 5 pm Replenish or reap. This helps control ozone. ..
Meanwhile, this week, Colorado leaders Withdrawal Proposal calling on companies with more than 100 workers to reduce vehicle movement after the Colorado Chamber of Commerce opposes. And the July 20 EPA deadline has passed for Colorado to comply with the 2008 federal limit of 75 ppb. Of course, there is also the current 70ppb limit that has been in force since 2015.
Going out is “relatively dangerous”
Ozone is formed when sunlight burns chemical gases (volatile organic compounds and nitrogen oxides). According to state officials, the main source is people burning fossil fuels in the automobile and oil and gas industries.Inhalation Ozone pollution Exacerbate respiratory illness Causes asthma attacks.
Recent University of Washington Research According to a consortium of scientists, at least 365,000 deaths worldwide each year (12,378 in the United States and 814 in Colorado) may be directly attributed to ozone.
Dr. James Crooks of Denver’s National Jewish Health said going out from July to October is “relatively dangerous” due to the increase in ozone over the last two years.
“Whether it’s ozone or wildfire smoke, if you have health concerns, if you’re a vulnerable person, or if you work outside, months each year will be dangerous to you,” he said. Told.
State air quality meteorologist Scott Landes added that ozone levels above 100 ppb are “arguably extreme and unusual.” Smoke from wildfire The western area plays a role.
In 1980, Denver’s ozone spike reached 146 ppb, one of the best recorded in Colorado. According to state analysts, ozone has declined slightly over the course of nearly 40 years, but the warm, hot and dry climate favors spikes.
Is it overkill or is it necessary?
Clean Air Defenders Asked State Leaders Will To meet health standards.
“We are not heading in the direction of cleaner air,” said Robert Ukayley, a lawyer at the Center for Biodiversity. He has been fighting for clean air at air quality control committee hearings for years.
On Wednesday, State Attorney General Phil Weiser withdrew the employee traffic reduction program proposed by the state’s aviation authorities after the Chamber of Commerce officials declared it overkill, unrealistic and unfair.
“How to commute to Colorado,” said Katie Wolff, government secretary general of the Colorado Chamber of Commerce, “should not be a state government concern.”
CDPHE director Jill Hansakar Ryan later posted in a post, state leaders “working hard to reduce ozone pollution and greenhouse gas emissions. The crime that Governor Police has charged us. Is. ” Regulations that require less car travel are “one of the key tools,” she said. “But in this case, it makes sense to use a voluntary approach.”
The withdrawal shocked the health group. “If we can’t even get employers and employees together to expand our options for working clean, it’s hard to imagine we’re going to do anything else we need to clean the air. “Danny Katz, director of the Colorado Public Interest Research Group, said. Bob Junke, the elder of climate change, said: It is also necessary to stop the burning of carbon to prevent global warming. “
If EPA authorities downgrade Colorado’s status, it will be the second reclassification in two years. Remixed gas requirements in nine county regions, including Metro Denver, such as Los Angeles, Chicago, Houston, and New York, will begin one year after the downgrade.
