   1. (1)Send a written request to the decision-maker, asking that he or she take the action originally asked of him or her;
   2. (2)Identify the statute, regulation, or other source of law that you believe requires the decision-maker to take the action being requested;
   3. (3)Describe the interest adversely affected by the decision-maker's inaction, including a description of the loss, impairment or impediment of such interest caused by the inaction; and
   4. (4)State that, unless the decision-maker either takes action on the written request within 15 days of receipt of your request, or establishes a date by which a decision will be made, you will appeal the decision-maker's inaction in accordance with this subpart.
3. (c)You must include a copy of your original request to the decision-maker, or other documentation establishing the date and nature of the original request.
