EPA proposes more stringent smog standard, will impact San Joaquin Valley
The United States Environmental Protection Agency (EPA) today announced that it is recommending a more stringent federal smog (ozone)
standard for ambient air quality. Based upon an analysis of the latest
scientific research on the effects of ozone on human health and the environment,
EPA is proposing to lower the 8-hour standard from its current level of
75 parts per billion (ppb) to somewhere in the range of 65 - 70 ppb.
EPA is also considering lowering the limit to a level as low as 60 ppb.
