INTRODUCTION

1.1

Scope

The original release of DOE-STD-1120-98 provided integrated safety management guidance for

enhancing worker, public, and environmental protection during all facility disposition activities.

Volume One of this Standard has been revised to provide a Department of Energy (DOE)

approved methodology for preparing a Documented Safety Analysis (DSA) for decommissioning

of nuclear facilities, as well as environmental restoration activities that involve work not done

within a permanent structure. Methodologies provided in this Standard are intended to be

compliant with Title 10 of the Code of Federal Regulations (CFR) Part 830, Nuclear Safety

Management, Subpart B, Safety Basis Requirements. As described in Appendix A, Table 2 of

this regulation, 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). Derivation of controls

is also necessary for facility decommissioning projects that involve more than "low level

residual fixed radioactivity."

DSAs must be compliant with the general requirement of 10 CFR 830.204, Documented Safety

Analysis, which requires: (1) a facility and work description; (2) a systematic identification of

natural and man-made hazards associated with the facility; (3) a evaluation of normal, abnormal

and accident conditions; (4) a derivation of hazard controls; and (5) a description of safety

management program characteristics, including criticality safety.

HAZWOPER requirements specifically focus on provisions for developing a Safety and Health

(S&H) program and site-specific health and safety plan. HAZWOPER applies to all worker

hazards, including physical hazards posed by deconstruction or environmental restoration work

(e.g., use of heavy equipment, excavations, confined space entry, and hot work). As stated in

DOE-STD-3009-94, Preparation Guide for U.S. Department of Energy Nonreactor Nuclear

Facility Safety Analysis Reports, "it is not the intention of the DSA to cover safety as it relates to

the common industrial hazards that make up a large portion of basic OSHA regulatory

compliance." Therefore, in the context of Subpart B requirements of Part 830, the scope of

HAZWOPER is taken to include those hazards, associated controls, and S&H programs that

must be identified and maintained within a Hazard Category 1, 2, or 3 facility's safety basis.

Existing S&H programs that are in place to meet DOE directives and standards, as implemented

through the Integrated Safety Management (ISM) process, may be acceptable mechanisms for

meeting HAZWOPER S&H program requirements. Where applicable to the safety basis, these

programs should be described in the DSA. However, compliance with ISM mechanisms or this

Standard should not be construed as automatically satisfying all health and safety plan (HASP)

provisions of HAZWOPER.

Volume Two of the Standard is much broader in scope than Volume One and satisfies several

purposes. Integrated safety management expectations are provided in accordance with facility

disposition requirements contained in DOE O 430.1B, Real Property Asset Management. The

collection of appendices in Volume Two also provides additional guidance that supplements

various practices described in Volume One.
