[en] The US Environmental Protection Agency (EPA) and the Washington State Department of Ecology (Ecology) have requested that the US Department of Energy (DOE), through the Environmental Restoration Contractor (ERC), perform removal actions at waste sites within the 100-BC-1 Operable Unit (OU) at the Hanford Site. To accelerate removal actions, the EPA (lead regulatory agency), Ecology (support regulatory agency), and DOE (responsible agency) have chosen an expedited response action (ERA) pathway for these removal actions. These removal actions will be nontime critical, and will follow the applicable sections of 40 CFR 300 Subpart E (EPA 1990), and the Comprehensive Environmental Response, Compensation, and Recovery Act of 1980 (CERCLA). The Resource Conservation and Recovery Act of 1976 and the Washington State Model Toxics Control Act (MTCA) are key sources of applicable or relevant and appropriate requirements (ARAR) for the removal actions. Section 7.0 of this plan details the ARARs. The 100-BC-1 Excavation Demonstration Project Plan provides information and guidance on the strategy planned to carry out the removal actions and meet all the project objectives. This document provides the objectives, site selection, subsystems, and phasing (Sections 2.0 through 5.0) of the project. Section 6.0 ties the previous sections together and details the strategy and data needs required to meet the project objectives while performing the removal actions. This strategy is applicable to all of the sites that will be addressed by this removal action project
