The U.S. Environmental Protection Agency (EPA) is conducting a joint review of the existing secondary (welfare-based) National Ambient Air Quality Standards (NAAQS) for nitrogen oxides (NOx) and sulfur oxides (SOx). EPA has decided to jointly assess the scientific information, associated risks, and standards relevant to protecting the public welfare from adverse effects associated with NOx and SOx because NOx, SOx, and their associated transformation products are linked from an atmospheric chemistry perspective, as well as an environmental effects perspective, and because the National Research Council (NRC) has recommended that EPA consider multiple pollutants, as appropriate. This is the first time since the NAAQS were established in 1971 that a joint review of these two pollutants has been conducted.
