BULK GAS TANK SYSTEM (NORTH LAYOUT)
San Luis Obispo CA 93401, CA · near San Luis County Rgnl (0.4 mi)
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
"New bulk gas tank system consisting of two portable hydrogen tank trailers one vertical argon tank with two vertical vaporizers and two vertical nitrogen tanks each with one vertical vaporizer. All equipment will be installed on a concrete pad. The new system will replace an existing bulk gas tank system that is being removed by the former supplier. Two alternative layouts are being submitted for this project to support ongoing design coordination. Each FAA Form 7460 1 represents a mutually exclusive layout option based on certified survey data. Only one layout will ultimately be constructed and the final configuration will not exceed the heights or locations identified in the submitted notices. Separate 7460 1 forms will be submitted for the cranes to be utilized during construction. The FAA will be notified via FAA Form 7460 2 for the selected layout prior to and during construction in accordance with 14 CFR Part 77 requirements."

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.
