Across
the country, more than 15,000 facilities report to the U.S. Environmental
Protection Agency that they use large amounts of extremely hazardous
chemicals. The law requires these facilities to disclose potential
chemical accidents, from the most-likely emergencies to a worst-case
scenario. Despite reporting large vulnerability zones and populations
at risk, few chemical-using plants have announced measurable
goals or timelines to reduce the size of the area at
risk from a potential worst-case chemical fire or spill. Below are
basic questions for companies and a hazard reduction hierarchy of
approaches for reducing the size of a company's vulnerability zone.
Hierarchy of Approaches
to Reduce Vulnerability Zones
[1]
Inherent Safety reduces or eliminates the possibility
of a chemical fire or spill, as the first resort. What you don't
have can't leak. For example, will the company substitute safer
chemicals? Cut dangerous storage and shipping? Use less hazardous
conditions (e.g., neutral pressures or temperatures)? Involve workers
in systems of safety analyses? Develop new micro-processing to eliminate
large-scale inventories? Establish a written policy for new
construction?
Example:
Ohio Citizen Action and the local community pressed American Electric
Power (Cheshire, Ohio) to select a urea-based pollution control
system rather than large-scale storage of ammonia that would have
endangered the surrounding community.
[2]
Add-on Controls reduce the likelihood of a chemical fire
or spill. Unlike inherent safety, which may improve efficiency,
add-on controls always cost money. For example, will the company
install secondary containment buildings? Use leak detectors and
automatic shutoffs? Add remote emergency shutdown capabilities?
Improve site security?
Example:
The Safer Neighborhoods Campaign persuaded Cincinnati Specialties
(of Cincinnati, Ohio) to build an enclosure to contain any accidental
releases of chlorine.
[3]
Emergency Planning mitigates the consequences of a chemical
fire or spill where add-on controls may fail. For example, has the
company established alert and warning systems? Prepared an emergency
plan? Maintained response equipment? Sponsored hazardous materials
training? Planned employee evacuation routes?
Example:
Many companies work with Local Emergency Planning Committees.
[4]
Buffer Zones keep unavoidably hazardous industries away from
places where people work, study, live, and play. For example, will
the company buy out neighbors? Support land use planning? Move to
a safer area?
Example:
Louisiana companies bought out homeowners in Morrisonville and Reville
Town, La.
