State fails to meet EPA standard set to protect public health; ozone problems to worsen with global warming
By Bob Berwyn
The modest steps taken by Colorado to try and improve air quality along the Front Range aren’t enough, according to the EPA. This week, the federal agency said the state has failed to meet air quality standards set to protect public health.
As a result, watchdog groups say the agency has fallen short, and the Center for Biological Diversity says it will sue the EPA because 17 states and the District of Columbia have failed to reduce ozone pollution, which poses serious threats to public health, wildlife and ecosystems. Essentially, environmental activists say the EPA has failed to meet standards set under the Clean Air Act. Continue reading “Environment: EPA faces ozone lawsuit”→
Across the U.S., ozone levels were higher on smoky days than on smoke-free days
Wildfire smoke on its own can trigger health warnings for direct exposure, and new research from Colorado State University suggests that there may be a more widespread impact after they linked smoke with elevated levels of ozone.
Environmentalists say new rule is to weak; industry asks Congress to step into the fray
The EPA’s new smog-fighting ozone standard is likely headed down the same path as the agency’s other recent initiatives to improve the environment.
Like the recently updated wetlands rule and the Clean Power Plan, the new ozone limit was immediately criticized from all sides. Environmental advocates said the agency ignored its own experts when it set the new limit at 70 parts per billion. Industry claims the new rule will cut profits and cost jobs.

Scientists say more monitoring will be crucial for regulators
FRISCO — Proposed new standards for harmful ozone pollution could present a big challenge for air quality managers at the state and local level. More monitoring is needed to help tell apart local sources from ozone that’s generated elsewhere, Boulder-based scientists wrote last week in Science.
