  We consider the edge and bulk conductances for 2D quantum Hall systems in
which the Fermi energy falls in a band where bulk states are localized. We show
that the resulting quantities are equal, when appropriately defined. An
appropriate definition of the edge conductance may be obtained through a
suitable time averaging procedure or by including a contribution from states in
the localized band. In a further result on the Harper Hamiltonian, we show that
this contribution is essential. In an appendix we establish quantized plateaus
for the conductance of systems which need not be translation ergodic.
