How long must an operator wait after filing a notification with the Utilities Technology Council (UTC) before operating on the 2200-meter or 630-meter band?

Amateur radio operators have secondary access to the 2200-meter and 630-meter bands. These low-frequency and medium-frequency bands are shared with utility companies that use Power Line Carrier (PLC) systems to control and monitor the electrical power grid. Because amateur transmissions could potentially disrupt these critical grid systems, FCC rules require amateurs to notify the Utilities Technology Council (UTC) prior to beginning operations. Once the notification is submitted, the amateur must wait 30 days. If the 30-day period passes and the UTC has not notified the amateur that their station is located within one kilometer of a PLC system using those frequencies, the amateur may legally commence operations. Explicit approval is not required; the rule relies on the expiration of the 30-day objection window.
