Background:
Methyl tertiary-butyl ether (MTBE) is a chemical compound primarily used as a gasoline
additive. It is one of a group of chemicals commonly known as "oxygenates" because the
chemicals raise the oxygen content of gasoline. At room temperature, MTBE is a volatile,
flammable, and colorless liquid that dissolves rather easily in water.
In 2002 legislation was enacted regulating the use of MTBE in gasoline. The law has two
parts: (1) it bans the intentional addition of MTBE to gasoline, motor fuel, or clean fuel for
use in Washington; and (2) it bans knowingly mixing MTBE in gasoline above 0.6 percent by
volume.
Summary:
The threshold for the ban on knowingly mixing MTBE in gasoline is reduced from 0.6
percent by volume to 0.15 percent by volume of MTBE.
