Whenever a hearing impaired person shall be authorized to be provided a qualified interpreter, the agency or law enforcement agency shall determine whether the qualified interpreter so provided is able to communicate accurately with and translate information to and from the hearing impaired person. If it is determined that the qualified interpreter cannot perform these functions, the agency or law enforcement agency shall obtain the services of another qualified interpreter or shall appoint an intermediary interpreter to assist the qualified interpreter in communicating with the hearing impaired person.
