The deadline for an Originating Depository Financial Institution (ODFI) to send a refused Notification of Change (NOC) is indeed 15 calendar days. This timeframe is established to ensure that the recipient of the NOC is given adequate time to process the change or address any potential issues.

The reasoning behind the 15-calendar-day timeframe is linked to the National Automated Clearing House Association (NACHA) operating rules, which aim to streamline processes and enhance communication among financial institutions. By having a specific period in which the ODFI must act, it helps maintain efficiency within the Automated Clearing House (ACH) network and ensures that all parties remain informed, reducing the likelihood of errors or disputes.

In contrast, the other options do not align with the established guidelines for handling refused NOCs. It is key for professionals in the industry to be aware of these timelines to facilitate smooth operations and compliance with NACHA regulations.
