  We study the effect of sterile neutrino on some low scale processes in the
framework of minimal extended seesaw (MES). MES is the extension of the seesaw
mechanism with the addition of sterile neutrino of intermediate mass. The MES
model in this work is based on $\Delta(96)\times C_{2}\times C_{3}$ flavor
symmetry. The structures of mass matrices in the framework lead to $TM_{1}$
mixing with $\mu \text{-}\tau$ symmetry. The model predicts maximal value of
Dirac CP phase. We carry out our analysis to study the new physics
contributions from the sterile neutrino to different charged lepton flavor
violation (cLFV) processes involving muon and tau leptons as well as
neutrinoless double beta decay (0$\nu\beta\beta$). The model predicts normal
ordering (NO) of neutrino masses and we perform the numerical analysis
considering normal ordering (NO) only. We find that sterile neutrino mass in
GeV range can lead to cLFV processes that are within the reach of current and
planned experiments. The GeV scale sterile neurtrino in our model is consistent
with the current limits on the effective neutrino mass set by $0\nu\beta\beta$
experiments.
