Process Section -- CAI Block Descriptor -- Define/Negotiate CAU Boundaries with NDEP A CAU flow and contaminant transport model utilizing Tritium and radionuclides with half-lives greater than Tritium (12.32 years) as the source term will be used to estimate a contaminant boundary for each CAU. The boundary will be composed of a perimeter boundary and a lower hydrostratigraphic unit boundary. The accepted contaminant boundary and other considerations will form the basis for a negotiated compliance boundary. |
