April 28, 2008: Increase in Code Orange and Code Red Air Quality Days
Expected Throughout Region
The Environmental
Protection Agency’s (EPA) National Air Quality Awareness Week kicks off today with the news
that an increase in the number of Code Orange and Code Red air quality days is expected in the
metropolitan Washington-Baltimore region this ozone season. The expected increase is the result of
EPA’s recent changes in the national air quality standard for
ground-level ozone which can cause respiratory problems and other health effects. The new
standard lowers the Code Orange and above range on the Air Quality Index (AQI), EPA’s
color-coded tool for communicating daily air quality, in order to better protect public health. The
change in the AQI is attributed to new research that finds there are greater health risks when
exposed to lower levels of ground-level ozone than previously thought.
According to Clean Air Partners, a regional partnership committed to improving air quality and protecting public health throughout the metropolitan Washington-Baltimore region, the number of Code Orange days (days that surpass the national standard level for safe or healthy air quality) will likely double this season. This increase will require residents to take action more frequently in order to reduce air pollution and protect the health of area residents.
“Although we have seen an improvement in the air quality throughout our region, EPA’s new standard demonstrates that ground-level ozone at lower levels is harmful to our residents’ health, especially sensitive groups,” said Joan Rohlfs, Chief of Air Quality Planning for the Metropolitan Washington Council of Governments and Program Manager for Clean Air Partners. “With the expected increase in Code Orange and Red days, residents will be called upon to do their part to help improve air quality and stay healthy. We view this tightening of standards as an opportunity for the region to further improve the air that we breathe.”
More than 7 million people in the metropolitan Washington-Baltimore region live in areas that exceed EPA’s standards for ground-level ozone and particle pollution. Sensitive groups, made up of 1.5 million area residents, are people with lung disease (asthma, emphysema, and chronic bronchitis), children, older adults, and people who are active outdoors and who may experience adverse health effects when air pollution levels are elevated for a prolonged period of time. EPA and Clean Air Partners recommend that during a Code Orange or above day, sensitive groups should limit their outdoor activity level and everyone should follow actions to reduce air pollution. Recommended actions include driving less by postponing errands, teleworking, carpooling or taking public transit, refueling after dark, and postponing mowing, all of which will impact air quality, improve health and reduce greenhouse gas emissions that impact climate change.

Despite the
new standard, the air quality in the metropolitan Washington-Baltimore region has improved over the
past decade. This is due in part to federal, state and local government regulations and pollution
control programs, continuous public education and outreach on air quality, as well as increased
voluntary efforts taken by participants and members of the Clean Air Partners program. There is also
evidence that overall public awareness of air quality has increased. Today, more than 60 percent of
the public is familiar with the AQI compared to only 45 percent in 1996. Since launching in May of
2007, there have been over 4 million visits to the Clean Air Partners website which supplies
information about regional air quality. Additionally, more than 1,200 individuals have registered to
receive Clean Air Partners’ AirAlerts, daily air quality forecasts and real time health
notifications, which provide timely air quality information, helping residents to protect their
health.
EPA estimates that the new standards will yield health benefits valued between $2 billion and $19 billion. Those benefits include preventing cases of bronchitis, aggravated asthma, hospital and emergency room visits, nonfatal heart attacks and premature death, among others.
