The FCC has slapped a $10,000 fine on Mapleton's Classic Hits KXDZ-FM/San Luis Obispo for violating the Commission's rules which requires broadcast stations to maintain a complete public inspection file. The noted violations involve Mapleton's failure to maintain multiple issues/programs list in the in KXDZ's public inspection file. The agency also gave Mapleton 30 days to submit a statement in compliance with the rules.

A FCC agent inspected the station in February, 2010, and the main studio of KXDZ, located in San Luis Obispo, CA. The agent reviewed the content of the station's public inspection file and discovered that required issues/programs lists were missing for the fourth quarter of 2007, the first, second, and third quarters of 2008, and the first and fourth quarters of 2009.

The agent discussed the file's deficiency with the Market Manager for the Mapleton stations, who agreed that the documents were missing from the file and indicated that the period for which the issues/programs lists were missing appeared to coincide with the departure of the station employee who had previously maintained the lists.

In its reply, Mapleton argued that the proposed forfeiture should be cancelled or reduced because Mapleton "is not responsible for maintaining public file material from the period of time prior to the station's current ownership, and because the amount of the proposed forfeiture improperly exceeds the forfeiture amounts imposed in similar circumstances."
