When an organization sets out to select risk management alternatives, it is actually trying
to control or even eliminate the potential hazard/s that may heighten the risk/s at the
project site. Risk can be defined as anything which may act as a contaminant or potential
source of harm and injury to humans, natural resources, and natural ecosystems within the
When the site being considered has been retired for some time, remedial actions may be
considered as a risk management alternative. The remedial actions may start from
non-implementation and culminate with total removal of contaminants found within the
project site. There may be one remedial action considered for implementation, or a
combination of different types of remedial actions – depending on the level of
contamination of the retired site. One factor which may determine how extensive remedial
actions should be is the projected future use for the project site. Another key
consideration is the existing regulatory requirements that apply to the project site.
Tiered Risk-Based Corrective Action
With this approach, project planners are able to:
– assess the conditions under which the project site may be reused.
– look into related health and safety hazards.
– create a risk management standard which is founded on the level of acceptable risk.
Usually, the tiered approach will culminate in the establishment of land use restrictions
for the project site. In addition, long-term site monitoring could also be implemented to
determine if the level of acceptable risk is attained in the end.
Land Use and Zoning Regulations
Zoning regulations are employed by public agencies to assess and permit future use for the
land in question. If permitted, the zoning restrictions concerning the project site may be
amended so that reuse can be initiated.
