Which step in the OEHSA process focuses on establishing the boundaries of the site assessment, where workplaces and AORs are delineated, and similar mission activities are associated to each other?

Which step in the OEHSA process focuses on establishing the boundaries of the site assessment, where workplaces and AORs are delineated, and similar mission activities are associated to each other?

• A. Site Reconnaissance
• B. Conceptual Site Model (CSM)
• C. Site Identification/Sectoring
• D. Reassessment

Answer: (C)

Setting the scope by defining where the assessment will focus and how the site is divided into manageable parts is the step that establishes the boundaries and organizes work. This is Site Identification/Sectoring, where the site’s extent is drawn, workplaces are identified, Areas of Responsibility are assigned, and similar mission activities are grouped together so they can be linked and analyzed coherently across the affected areas. Site Reconnaissance is about on-site data gathering to support understanding of conditions; the Conceptual Site Model combines collected information into a structured representation of sources, pathways, and receptors; and Reassessment is the process of reviewing and updating the assessment as conditions or information change. The boundary-setting and sectoring focus described aligns specifically with Site Identification/Sectoring.
