Documented Safety Analysis for Environment Restoration

DOE-STD-1120-2005/Vol. 1

4.0

DOCUMENTED SAFETY ANALYSIS FOR ENVIRONMENTAL

RESTORATION

Environmental restoration activities that are not performed within permanent structures are

subject to the requirements of 10 CFR 830, Subpart B1. It is anticipated that many of these

activities, especially non-intrusive environmental restoration, may not present significant nuclear

or chemical risks to workers or members of the public. Chapter 4 of this Standard is applicable

to the small subset of environmental restoration projects that require a DSA, based on the results

of a final hazard categorization performed in accordance DOE-STD-1027-92.

As described in 10 CFR 830, Appendix A, Table 2, contractors may prepare a DSA by using the

method described in DOE-STD-1120-98, or successor document, and the provisions of 29 CFR

1910.120 or 29 CFR 1926.65, Hazardous Waste Operations and Emergency Response

(HAZWOPER). DSAs must also be compliant with the general requirement of 10 CFR

830.204, Documented Safety Analysis, which require (1) facility and work description; (2)

systematic identification of natural and man-made hazards associated with the facility; (3)

evaluation of normal, abnormal and accident conditions; (4) derivation of hazard controls; and

(5) description of safety management program characteristics, including criticality safety.

As explained in Section 1.1 of this Standard, the DSA isn't expected to address the full scope of

standard industrial hazards and controls typically covered by HAZWOPER. An acceptable DSA

format and content that meets the requirements of 10 CFR 830.204 and the provisions described

in 10 CFR 830, Subpart B, Appendix A, Table 2 is described according to the sections below.

An overview of the DSA format is show in Figure 3. While these topics may be described in a

HAZWOPER health and safety plan, it is recommended that information be presented in a

separately prepared DSA, providing a clearer distinction of facility safety basis information that

is subject the Unreviewed Safety Question process.

4.1

Restoration Project and Site Description

Background information on the environmental restoration site and planned restoration-related

activities should be presented to the extent necessary to facilitate an understanding of the hazard

analysis. It is important that this section of the DSA be consistent with the scope of planned

activities as agreed upon with federal and authorized State environmental regulators.

4.1.1

Site Location

The location of the facility and its relationship to nearby structures is important data for

understanding potential on-site or off-site impacts from environmental restoration operations.

Nearby facilities, structures and buildings in which there may be persons or equipment that could

be affected by events occurring during the environmental restoration project, and their physical

relationship to the facility being decommissioned, should be listed. The locations of potentially

affected members of the public near the site should also be given. Transportation routes for

1. These activities are also subject to regulation under the Resource Conservation and Recovery Act and/or the

Comprehensive Environmental Response, Compensation, and Liability Act, as well as requirements specified in

federal facility agreements and agreements with authorized States.
