We study impurity scattering in the normal and $$d$$-wave superconducting states of line nodal semimetals and show that, due to additional scattering phase space available for impurities on the surface, the quasiparticle interference pattern acquires an extended character instead of a discrete collection of delta function peaks. Moreover, using the $$T$$-matrix formalism, we demonstrate that the conventional behavior of a scalar impurity in a $$d$$-wave superconductor breaks down on the surface of a line nodal semimetal in the quasi-flat-band limit.
