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
"Sunriver Water LLC is proposing a 3.25 million gallon reinforced concrete water tank to increase the capacity of water at the site. The proposed tank dimensions are as follows: Diam = 137' Height = 45'"
