The new code version of EMC3, which can deal with non-uniform cross-field transport coefficient, is benchmarked with analytical problem and a finite difference method. It has been confirmed that for arbitrary spatial change of the transport coefficient the error is suppressed below tolerable level for the purpose of comparison with experiments. The first implementation of the new code in LHD stochastic layer shows existence of significant change of cross-field transport in radial direction. The location of the change corresponds to the boundary between long flux tubes region and the edge surface layers (where long and short flux tubes co-exist, i.e. laminar zone).
