Let $(X,o)$ be a 3-dimensional terminal singularity of type $cD$ or $cE$
defined in $\mathbb{C}^4$ by an equation non-degenerate with respect to its
Newton diagram. We show that there is not more than 1 non-rational divisor $E$
over $(X,o)$ with discrepancy $a(E,X)=1$. We also describe all blowups $\sigma$
of $(X,o)$ such that $E=\Exc(\sigma)$ is non-rational and $a(E,X)=1$.
