Site Control

DOE-EM-STD-5503-94

9.0. SITE CONTROL

9.1. BACKGROUND

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

that the posting requirements of the DOE Radiological Control Manual are properly addressed

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

zones,
