Middleton airport adopts public FAQ after vendor briefing on 100-octane unleaded aviation fuel

The Middleton Airport Commission on April 4 adopted a public FAQ explaining how the airport plans to respond as 100‑octane unleaded aviation fuel (100UL) becomes available. The commission heard a technical and commercial briefing from Taylor Hall of the fuel blender (referred to in the packet as “Gammy”), who described G100 UL as FAA‑approved for piston‑engine aircraft and explained logistical options for delivering small quantities to regional airports.

Hall told commissioners the product has passed bench and field testing and that distributors are preparing to supply larger commercial quantities. He described transitional approaches — split loads shared among airports, rented ISO containers with pumping systems, or temporary 1,000‑gallon truck deliveries — and said supplemental type certificates (STCs) to allow use in specific aircraft are being offered and can be issued and documented electronically at events or on‑site.

Commissioners and staff focused the FAQ’s final wording on two public concerns: the FAA’s timeline and when the fuel will be available to Middleton through regional distributors. Commissioners removed technical aviation jargon and agreed to language that explains the FAA has scheduled a transition to 100‑octane unleaded aviation fuel by about 2030 and that local availability depends on distributor capacity and competitive pricing. The commission also agreed to emphasize safety: Hall said blending strategies already in use preserve aircraft safety during transition blends and that the company would provide test results and data on engine performance.

The FAQ adoption followed brief discussion of local on‑site storage: staff confirmed the airport already maintains a 10,000‑gallon tank that could be converted when commercial supply and price are appropriate; the commission removed a proposed reference to using the airport’s 1,000‑gallon truck as a planned transitional solution because of cost and logistic concerns. Commissioners asked the city to publish the FAQ on the airport page of the city website and to continue working with vendors and regional partners to monitor distribution and pricing.

The commission’s adoption was a motion approved by voice vote. The meeting packet and the vendor briefing indicate the airport will continue regularly scheduled outreach and will invite the vendor to provide further updates as new information and distributor commitments become available.
