  We analyze the prospects of a feasible, Brookhaven National Laboratory based,
very long baseline (BVLB) neutrino oscillation experiment consisting of a
conventional horn produced low energy wide band beam and a detector of 500 kT
fiducial mass with modest requirements on event recognition and resolution.
Such an experiment is intended primarily to determine CP violating effects in
the neutrino sector for 3-generation mixing. We analyze the sensitivity of such
an experiment. We conclude that this experiment will allow determination of the
CP phase $\delta_{CP}$ and the currently unknown mixing parameter
$\theta_{13}$, if $\sin ^2 2 \theta_{13} \geq 0.01$, a value $\sim 15$ times
lower than the present experimental upper limit. In addition to $\theta_{13}$
and $\delta_{CP}$, the experiment has great potential for precise measurements
of most other parameters in the neutrino mixing matrix including $\Delta
m^2_{32}$, $\sin^2 2\theta_{23}$, $\Delta m^2_{21}\times \sin 2 \theta_{12}$,
and the mass ordering of neutrinos through the observation of the matter effect
in the $\nu_\mu \to \nu_e$ appearance channel.
