The Advisory Health Board shall make and may amend or repeal regulations governing disposal, transportation, interment and disinterment of dead bodies and fetal remains, in order to protect the public health and promote the integrity and efficacy of death and fetal death registration. However, the Advisory Health Board shall not, pursuant to the authority contained in this or any other act, promulgate any regulation which would require that the top of the outer case containing a casket be buried a distance of more than two feet from the natural surface of the ground.
