Del. Code tit. 16, § 3156

The Department shall modify and relax its regulations and restrictions relative to the disinterring and reinterring of dead bodies, including the securing of separate disinterment and transfer permits of the bodies in those cases where the bodies are in public or private burying grounds which have been condemned by this State or the United States government for the purposes of public improvement, in order to enable the carrying into effect of complete removals in such cases to the full extent that the same can be accomplished, in the opinion of the Department, by licensed undertakers under its supervision and without jeopardizing the public health.
