The Environmental Planning Group (EPG) takes an active role to insure that highway projects do not expose construction workers or the general public to hazardous materials, whether it is during or after construction.
Studies are conducted to identify hazardous materials and asbestos involvement, such as the leaking underground storage tanks. These studies vary in depth of investigation depending on nature of project, types of land uses, and the amount of ground disturbance.
The most basic study to determine prescence of hazardous materials
is called a Preliminary Initial Site Assessment (PISA),
which is used on all roadway projects. Should hazardous materials
become identified, such studies escalate into Phase I,
Phase II, and Phase III assessments.
These more intense studies often result in mitigation that could
include remediation, before construction begins.
