| Both CNG (compressed natural gas) and LNG (liquefied compressed
natural gas) fuels have been shown to decrease polluting emissions
by as much as 87
percent
over diesel fuel. In 2000, the South Coast Air Quality Management
District (SCAQMD) reinforced this decision by mandating that
all new transit buses be powered by alternative, low-emission fuels.
In December 2000, residents of the neighborhood surrounding the
Omnitrans facility expressed their ongoing
concerns regarding the occasional release of odorized CNG from
the fueling station. A number of community meetings were held
to discuss these concerns, and as a result in April 2002, Omnitrans
has switched to odorless LNG.
LNG is used by the Orange County Transportation
Authority, as well as transit systems in Arizona, Texas and Oregon.
The United Parcel Service uses LNG at its Ontario facility.
