9.0. SITE CONTROL
The site control program at hazardous waste sites is used to control the activities and movement
of people and equipment in order to minimize the potential for worker exposure to hazardous
substances. The provisions of 29 CFR 1910.120(d) require that an appropriate site control
program be developed prior to the implementation of cleanup operations.
The site control program should be established during the planning stages of a hazardous waste
operation. It should be modified as new information becomes available. The appropriate
sequence for implementing site control measures should be determined on a site-specific basis.
It may be necessary to implement several measures concurrently. Care should be taken to ensure
and that procedures are implemented. For the purpose of this chapter, a Radiological Area will
generally equate to an Exclusion Zone, a Radiological Buffer Area will generally equate to a
Contamination Reduction Zone, and a Controlled Area will generally equate to a Support Zone.
This equivalency is identified in Table 9-1.

The overall objective of the site control component of the HASP is to specify procedures to
minimize employee exposure and protect the public from hazardous substances and to prevent
unauthorized access to the site.
Procedures to meet the objectives of the site control program should include the following:
Coordination with site management in the establishment of site boundaries,
Development of a map of the hazardous sites which represents a central source of
information about the site,
Establishment of work zones to prevent unauthorized personnel from entering controlled
