The science advisers actually had urged the agency to consider tougher standards:
“[i]f the epidemiological evidence is given additional weight, the conclusion could be drawn that health effects are occurring at levels below the current standard, which would support the tightening of the current standard.” Taking this into account, the Panel further advised that “revisions that result in lowering the standard should be considered” (Brain and Samet, 2010b).We can only hope this is not a precedent for the more crucial ozone decision.
Here is what our friends at the American Lung Association say about this:

EPA’s Decision to Retain Weak Carbon Monoxide Air Quality Standards
Fails to Protect Public Health
Targeted Roadside Monitoring Network to Let Public Know
Where Unhealthy Air Exists in Communities
Statement of Charles D. Connor, President and Chief Executive Officer, American Lung Association
WASHINGTON (August 15, 2011) –The U.S. Environmental Protection Agency (EPA) today reaffirmed the current the national air quality limits for carbon monoxide air pollution, and missed the opportunity to strengthen this standard. This is a disappoint ing step, and a sad 40th anniversary for these weak national standards, set in 1971. In this decision, EPA did not accept the Agency’s own evidence that the 1971 standards cannot protect public health, which is the sole purpose of the air quality standards. Nor did the EPA follow the recommendation by independent expert scientists who advise them, the Clean Air Scientific Advisory Committee, to adopt stronger, more protective standards.
EPA did target the monitoring for this dangerous pollutant, a critical step to let the public know where unhealthy levels of this dangerous pollutant are in their communities. More than 45 million people who attend school, live near, commute, or work on or near transportation routes have their health placed at risk by exposure to carbon monoxide and other traffic pollutants. Lack of adequate monitoring has meant that they cannot adequately know the threats to their health, and has limited research and cleanup.
All areas in the nation currently comply with the 1971 standards. Levels have dropped significantly since the 1970s, thanks to reduced emissions from vehicle exhaust. Yet large, repeated epidemiological studies provide evidence that the public is harmed by carbon monoxide at levels currently found in our nation. EPA noted multiple epidemiological studies that found links between CO exposure well below the existing standards, and harm to public health, including increased risk for hospital admissions for children with asthma and for adults with chronic obstructive pulmonary disease, as well as increased risk to people with cardiovascular disease.
Millions of Americans are unprotected by the current air quality standards for carbon monoxide. Children with asthma and adults with chronic obstructive pulmonary disease (COPD) should be free to work or play outdoors without fear that air pollution will trigger asthma attacks or worsen their ability to breathe and send them to the hospital. People who live near or work on or near busy highways should not risk their lives and their health.
