Notwithstanding another provision of this chapter, when a suspension is based on an occurrence which endangers the safety of a person or appears likely to prove physically harmful to the service delivery system of the LEC, the telephone company need give no written notice before suspension if the LEC honestly and reasonably believes the grounds do exist. At the time of suspension, the LEC shall mail a notice of suspension to the customer's billing address.
