What this outcome means

The FAA studied the proposal and concluded it would not be a hazard to air navigation. A no-hazard determination is not permanent — it carries an expiration date, and if the structure is not built by then the case has to be re-filed.

The proposal, in the filer's words

"Existing 584ft OAGL Building constructed 2/5/2000. Filing to add frequency deployments. No other changes proposed. Per prior FAA ASN M&L = Red Lights. Per FCC ASR M&L = FAA Chapters 4 5 13."
