ARB rescinds outdated southern California ozone plan
State calls on U.S. EPA to review, approve more protective

SACRAMENTO: The California Air Resources Board is calling on the
U.S. Environmental Protection Agency to approve its plans to meet
the eight hour ozone standard for both Southern and Central
California and is revoking its plan to attain the one-hour ozone
standard in Southern California.

ARB staff decided to pull the outdated 2003 one-hour ozone
standard plan back since there is already a one hour State
Implementation Plan, or "SIP," in place for Southern California
that the U.S. EPA approved in 2001. This SIP has helped reduce
smog-forming emissions in Southern California at unprecedented
rates: Although ozone concentrations in the South Coast were
more than twice the standard during the mid-1990s, today more
than 60 percent of the area's population live and work in areas
that meet the standard. These areas include nearly all of Orange
County and the coastal region of Los Angeles County.

ARB will not rescind its one hour ozone SIP for the Central
Valley since there is no other plan in place for reducing the
region's smog-forming emissions.

"At this point, the current SIP is no more than a paperwork
exercise. We have the framework in place to reduce South Coast
ozone emissions already and have passed the halfway mark in
terms of being where we need to be by 2010," said ARB Chairman
Mary Nichols. "We now need the U.S. EPA to act on our eight-hour
ozone standard plans."

The U.S. EPA set a new eight-hour ozone standard in 1997 that
largely supersedes the previous one-hour standard since it is
more stringent and protective. The eight-hour standard protects
the public against chronic health effects from day-long episodes
to unhealthy ozone concentrations as compared to one-hour

ARB submitted eight-hour ozone SIPs for both the Central Valley
and Southern California to the U.S. EPA in November. These SIPs
include measures that will reduce thousands of deaths and
illnesses associated with smog exposure. The U.S. EPA never
acted on the 15-year-old plan that ARB is rescinding today.

The Air Resources Board is a department of the California
Environmental Protection Agency. ARB's mission is to promote and
protect public health, welfare, and ecological resources through
effective reduction of air pollutants while recognizing and
considering effects on the economy. The ARB oversees all air
pollution control efforts in California to attain and maintain
health based air quality standards.
