On July 15, the Environmental Protection Agency published a proposed rule revising the primary national ambient air quality standard (NAAQS) for oxides of nitrogen measured as nitrogen dioxide, or NO2. The proposal will establish a new short-term standard within the range of 80 to 100 parts per billion (ppb) NO2, and will require NO2 monitoring along major highways. A final rule will be issued by January 22, 2010.

On June 30, the Environmental Protection Agency granted California the authority to regulate emissions of greenhouse gases from motor vehicles, beginning with the 2009 model year. In overturning a previous decision, EPA has waived federal Clean Air Act pre-emption of more stringent state regulations.
