    Conditions/Notes
                          MUSIC modelling shall be carried out as follows:
                          A generic node is to be used in MUSIC with a high flow bypass set to the applicable TFR (see
                          table below) for the size of the Atlan Stormsack proposed and with inlet and outlet
                          concentrations as follows:
