(b) If the debtor's arguments appear to have merit, the NRC may extend the interest waiver period as described in §15.37(j) pending a final determination of the existence or amount of the debt.

(c) The NRC may investigate the facts involved in the dispute and, if it considers it necessary, arrange for a conference at which the debtor may present evidence and any arguments in support of the debtor's position.
