R.I. Gen. Laws § 23-1-20
Whenever the director determines that there are reasonable grounds to believe that there is a violation of any law administered by him or her or of any rule or regulation adopted pursuant to authority granted to him or her, the director may give notice of the alleged violation to the person responsible for it. The notice shall be in writing, shall set forth the alleged violation, shall provide for a time within which the alleged violation shall be remedied, and shall inform the person to whom it is directed that a written request for a hearing on the alleged violation may be filed with the director within ten (10) days after service of the notice. The notice will be deemed properly served upon a person if a copy of the notice is served upon him or her personally, or sent by registered or certified mail to the last known address of that person, or if that person is served with notice by any other method of service now or later authorized in a civil action under the laws of this state. If no written request for a hearing is made to the director within ten (10) days of the service of notice, the notice shall automatically become a compliance order.
