The 1-710 freeway plays a crucial role as a com-
ponent of the regional, statewide, and national
movement of goods and people. The 1-710 freeway
extends from the ports in the south (Port of Los
Angeles and the Port of Long Beach), northward to
East Los Angeles connecting major Southern Cali-
fornia distribution centers and railways (Figure 1).
The 1-710 freeway passes through 15 cities and un-
incorporated areas with a population of over 1 mil-
lion residents - about 70% of which are minority
and disproportionately low income populations. The
area is dense with truck traffic, industrial facilities,
residences, schools, daycares, and senior centers.
The U.S EPA is working with state and local govern-
ments as well as local nonprofit organizations to
identify and address the concerns of the communi-
ties affected by the corridor (see http://
www.epa.gov/region9/ei/enforcement.htmn.
What are the Environmental Issues?
As a result of population growth, increased volumes
of goods, and an aging infrastructure, the corridor
is experiencing high volumes of traffic, which brings
with it safety and environmental concerns. Here are
some facts:
• The Ports of Long Beach and Los Angeles are
the entry point of 40% of all imports to the U.S.
and 20% of diesel particulate emissions in
Southern California.
• Approximately 2,000 premature deaths are
associated with diesel emissions in the South
Coast Air Basin.
• The region has persistently exceeded national
air quality standards for carbon monoxide,1-
hour and 8-hour ozone, and particulate matter
2.5 and 10.
Figure 1
• The American Lung Association's "State of the
Air 2009" Report identifies Los Angeles as the
most polluted city in the nation by its levels of
ozone and particulate pollution.
• In 2009, 78 facilities within the I-710 corridor
reported a total of 1.7 million pounds of toxic
chemical release under the Toxics Release Inven-
tory Program.
• The largest sources of air toxics in the South Coast
is mobile sources (cars, trucks, construction
equipment, trains), which is not reflected in the
TRI.

Total Releases 2009
The primary releases in the I-710 corridor are air
emissions (836,215 pounds) and off-site releases
(823,520 pounds). Off-site releases include trans-
fers to other facilities for disposal, treatment and
recycling.

Refineries are the largest category in the South
Coast. South Coast has various air toxics regula-
tory programs, includingthe Toxic Hotspot program,
which the refineries have to comply with. EPA
is working on the residual risk standards for refin-
eries.
The largest release from refineries is ammonia,
which is half of the total refinery emissions. Am-
monia is a respiratory irritant. It is regulated by the
state/local agencies.
South Coast has a long history of implementing the
most stringent control measures available. However,
the air quality continues to be poor, partly due to a
combination of adverse meteorology and topogra-
phy.
