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
"Update to previous determination that was filed for 37'. Requested height is now 42'"

Check Part 77 and the tower's line of sight before you file
