The rule
Does South Dakota license radon professionals?

South Dakota is not on the list of states with radon credentialing programs that EPA's state contacts page publishes. Licensing is done by the state, not by the national programs, and EPA requires states that receive radon grants to give the public a list of only those providers credentialed by the state or by NRPP or NRSB.
Radon411 reads no licensing list for South Dakota; South Dakota's radon program is the place to ask who works there.
