Project W-3 14, (97-D-402) Tank Farm Restoration and Safe Operations is a multi-year, multi- phase project established to upgrade selected 200 East and West Area Tank Farms to support the long-term mission of waste storage, retrieval, and transfer for vitrification. Key drivers for these upgrades include the planned timetable for transfer of waste to the privatized vitrification facility, regulatory compliance requirements (i.e., Washington State and Federal Regulations), and the Tri-Party Agreement (TPA). The previous baseline scope for Project W-3 14 was established based upon tank farm system assessments performed five to six years ago and was reflected in the previous baseline cost estimate, the Accelerated Replanning Estimate, completed in July 1997. The Accelerated Replanning Estimate splits the project into hvo phases: Phase 1 provides upgrades necessary to assure reliable waste retrieval and transfer to the anticipated vitrification plant. Phase 2 provides upgrades to selected primary and annulus tank farm ventilation systems that are required for compliant waste transfer, as well as other compliance-based upgrades to existing River Protection Project (WP) facilities and systems. The Accelerated Replanning Estimate provided the basis for Baseline Change Request TWR 97-066, which identified Phases 1 and 2 as $95 million and $206.5 million, respectively.
