NewOn January 22, 2010, EPA strengthened the health-based National Ambient Air Quality Standard for nitrogen dioxide (NO2). The new standard will protect public health, including the health of sensitive populations – people with asthma, children and the elderly. EPA is setting a new 1-hour NO2 standard at the level of 100 parts per billion (ppb). This level defines the maximum allowable concentration anywhere in an area. In addition to establishing an averaging time and level, EPA also is setting a new “form” for the standard. The form is the air quality statistic used to determine if an area meets the standard. The form for the 1-hour NO2 standard is the 3-year average of the 98th percentile of the annual distribution of daily maximum 1-hour average concentrations. EPA also is retaining, with no change, the current annual average NO2 standard of 53 ppb, which Utah has never exceeded. Below is where Utah stands with the new NO2 Standard.

NewOn November 13, 2009 EPA published, in the Federal Register, its final area designations for the 2006 PM2.5 National Ambient Air Quality Standards. EPA had already announced its intentions concerning these areas on October 8.  Most significantly, the new FR notice includes an effective date (December 14, 2009) for the area designations. Many significant deadlines concerning the administration of the 2006 PM2.5 health standards will be measured from this effective date. Learn more about this action and its significance at the following locations:
