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
"The requested change is to bring to the current lighting circular 70/7460-1M Obstruction Marking and Lighting a med-dual system - Chapters 4 8(M- Dual) &15"
