The Division of Child Protective Services may examine the circumstances and system relating to the placement of any dependent child in any home and may inspect and investigate the particular home to which such dependent child is to be or has been assigned, and, whenever satisfied that a child has been placed by any person, institution, agency, association, corporation or organization in an improper home, it may order its transfer to a proper one or its removal from the State, and, if the order is not obeyed within 30 days, it shall itself take charge of the child, returning it to the person, agency, institution, association, corporation or organization responsible or otherwise providing for it. Any such person, agency, institution, association, corporation or organization failing to remove such child after such notice shall at once pay the State such sum as the State may have expended in the care, maintenance or transportation of such child.
