As an example of the hazards associated with styrene, an
explosion that occurred in the province of Quebec in 1966 resulted
in 11 deaths, 7 injuries and significant property loss.
Of the 52 substances evaluated, 33 substances and classes of
these substances (a total of 41 substances) were found to have the
potential to create environmental emergencies due to their
significant risk to the environment and human life in the case of
accidents, vandalism or terrorist acts.
Facilities that handle these 41 listed
substances at or above regulated quantities are required to develop
environmental emergency (E2) plans, if they are not already in
E2 plans require that individuals and industrial facilities

regulations have plans for and can manage the consequences of an
unintended release of the substance into the environment.
The amendments include an exemption that reduces administrative
burdens for some facilities in the propane gas sector. Facilities
with propane in storage containers are excluded from the E2
