rocedural measures proposed for its facility and the SRP acceptance criteria and evaluate how the proposed alternatives to the SRP acceptance criteria provide acceptable methods of compliance with the NRC regulations. 2.4.13-4 Revision 3 - March 2007 Appropriate sections of the following Regulatory Guide are used by the staff for the identified acceptance criteria: Regulatory Guide 1.113 as it relates to selection of surface water models. The staff uses best current practices to analyze groundwater transport of radioactive liquid effluents. 1. Alternate Conceptual Models: Alternate conceptual models of hydrology in the vicinity of the site are reviewed. The description of these alternate conceptual models should be sufficient to bound the hydrogeological conditions at the site that define the transport of radioactive liquid effluent in ground and surface water environments. 2. Pathways: The bounding set of plausible surface and subsurface pathways from the points of release are reviewed. The description of these pathways should provide sufficient information including data to ensure that the bounding set of plausible pathways that may result in the worst-case contamination are adequately identified. Estimates of physical parameters necessary to calculate the transport of liquid effluent from the points of release to the site of existing or known and likely future users should be described. 3. Characteristics that Affect Transport: Radionuclide transport characteristics of the groundwater environment with respect to existing and known and likely future users should be described. Estimates and bases for coefficients of dispersion, adsorption, groundwater velocities, travel times, gradients, permeabilities, porosities and potentiometric map or piezometric levels between the site and existing or known and likely future surface and groundwater users should be described and should be consistent with site characteristics and conform to the stipulation of 10 CFR
