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
"Filing for correction of height from 195' to 197'. Tower is currently 197'. We request no marking/lighting requirements."
