14 Areas Don't Meet Air Quality Standard For Fine Particulates, EPA Says in Proposal

摘要

The Environmental Protection Agency has identified 14 areas in six states as not meeting the 2012 national ambient air quality standard for fine particu-late matter and intends to designate those areas as non-attainment areas, according to the agency's website. The EPA posted a list of areas that don't meet the annual fine particulate matter standard of 12 micrograms per cubic meter, based on monitoring data from 2011-2013. Those areas include Cleveland, the Los Angeles-South Coast Air Basin and the San Joaquin Valley. The agency in January 2013 tightened the annual, health-based national ambient air quality standard for fine particles, which had been set at 15 micrograms per cubic meter, a move that was projected to result in annual health benefits of as much as $9.1 billion (78 Fed.
