Environmental Groups Bring Suit Against EPA to Require Air Monitoring Along So-Cal Freeways

houses1-300x209On Tuesday, the Natural Resources Defense Counsel (NRDC), Physicians for Social Responsibility-Los Angeles and Communities for a Better Environment brought a suit against the Environmental Protection Agency (EPA) for EPA’s approval of the South Coast Air Quality Management District’s (SCAQMD) 2011 Annual Air Quality Monitoring Network Plan on November 1, 2011 (the Air Monitoring Plan). 

The SCAQMD is the air pollution control agency for all of Orange County and the urban portions of Los Angeles, Riverside and San Bernardino Counties.  The Air Monitoring Plan describes the network of ambient air quality monitors within the SCAQMD’s jurisdiction (click here for the final plan).  Federal law requires EPA to review the Air Monitoring Plan annually to identify the need to make any changes to the air monitoring requirements. 

Although the environmental groups’ opening brief is not due until the end of March, according to NRDC’s press release, the focus of the suit will be that EPA violated the Clean Air Act by approving the Air Monitoring Plan even though it does not require air quality monitoring along Southern California freeways.  NRDC contends that such monitoring is necessary to “better inform the local air district about the hazardous levels of particulate air pollution, and to arm them with the information necessary to take action to protect the region’s residents.”  The environmental groups are seeking the installation of air monitors along the region’s highways.
