We explore an alternative strategy to determine the neutrino mass hierarchy by making use of possible future neutrino facilities at Fermilab. Here, we use CPT-conjugate neutrino channels, exploiting a nuµ beam from the NuMI beamline and a [overline nu ]e beam from a beta-beam experimental setup. Both experiments are performed at approximately the same <E>/L. We present different possible accelerator scenarios for the beta-beam neutrino setup and fluxes. This CPT-conjugate neutrino channel scenario can extract the neutrino mass hierarchy down to sin22theta13[approximate]0.02.
