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

"City Light and Power CLP will construct a microgrid to provide backup power to important emergency services for Joint Base Lewis McChord The project consists of three 15MW LNG fueled generators 3 large Battery Energy Storage Systems BESS one Power Distribution Center PDC and some other minor controls CLP will use a 270T mobile crane to lift the major pieces of equipment off the flatbed delivery vehicles and set them on their respective pads on the project site The heaviest pieces of equipment will be the three BESS each weighing approximately 80000 lbs No piece of equipment is taller than 10 feet in height The mobile crane will operate in a 100 diameter of the lat long provided and its height and operating diameter are provided as worst case scenario for planning and permitting purposes"

Screening a structure of your own?

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

LOS Analyzer screens a proposed structure against FAA Part 77 surfaces and the control tower's sightline to the runway, terrain-aware, in minutes. It is a preliminary screening — not an FAA determination and not a substitute for a licensed engineering review.
