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
"T-Mobile proposes to install antennas on an existing 308' building that was built in 1959. The new overall height of the building with the antennas and FRP screen will be 315'."
