This analysis calculates the offsite radiological consequence of the bounding unplanned excavation/drilling of 200 Area soils accident. The US. Department of Energy (DOE) standard DOE-STD-3009-94, ''Preparation Guide for U.S. Department of Energy Nonreactor Nuclear Facility Documented Safety Analyses'', requires the formal quantification of a limited subset of accidents representing a complete set of bounding conditions. The results of these analyses are then evaluated to determine if they challenge the DOE-STD-3009-94 Appendix A, ''Evaluation Guideline,'' of 25 rem total effective dose equivalent to identify and evaluate safety-class structures, systems, and components. This document supports the development of the unplanned excavation/drilling of 200 Area soils accident in the tank farm documented safety analysis. Consequently, it: (1) Provides a comprehensive review of potential unplanned excavation scenarios (i.e., backhoe, buried pressurized line ruptures, drilling, Guzzler vacuum) to determine the representative activity that would bound unmitigated, unplanned, or inadvertent excavations of 200 Area soils. (2) Evaluates radiological isotope inventories of all current Tank Farm Contractor (TFC) liquid waste disposal sites [i.e., cribs, ditches, and ponds (including French drains)], and isotope inventories of unplanned release sites (UPR) and plume columns. (3) Establishes the radiological consequences to the maximum offsite individual (MOI) from an unplanned/inadvertent 200 Area soil disturbance based on bounding site development and representative accident determination.
