At the request of Savannah River Nuclear Solutions (SRNS) management, a review team composed of experts in atmospheric transport modeling for environmental radiation dose assessment convened at the Savannah River Site (SRS) on August 29 - 30, 2011. Several issues were presented at the meeting for discussion. This is a short summary that is organized in accordance with the primary issues discussed, which is not necessarily a chronological record. Issues include: SRS Meteorological Data and its Use in MACCS2; Deposition Velocities for Particles; Deposition Velocities for Tritium; MACCS2 Dispersion Coefficients; Use of Low Surface Roughness in Open Areas; Adequacy of Meteorological Tower and Instrumentation; Displacement Height; and Validity of MACCS2 Calculations at Close-in Distances. A longer report will be issued at a later date that expands upon these topics and recommendations.
