Underground Hydrant System Purging: Managing Transition Protocols When Introducing SAF into Conventional Fuel Hydrants

Engineering protocol for cleaning, pressure-testing, and flushing multi-user airport hydrant systems prior to sustainable fuel injection.

Executive Summary & Infrastructure Context

Sustainable aviation fuel (SAF) infrastructure, blending systems, and book-and-claim supply chains require rigorous engineering precision and regulatory compliance. This technical brief outlines the core operational standards necessary to deploy green fuel solutions across executive aviation facilities.

Primary Intelligence Question

What are the mandatory operational and engineering steps required to safely transition a multi-user airport hydrant system from conventional fuel to high-blend sustainable aviation fuel (SAF) while ensuring system integrity and compliance with ASTM D7566?

Key Intelligence

The brief specifies that transitioning conventional fuel hydrants to accommodate SAF requires rigorous purging, cleaning, and pressure-testing of underground hydrant systems prior to SAF injection. This process must include dedicated bowser fleets and static dissipator additives to prevent contamination. Additionally, 100% replacement of elastomer seals and modifications to filtration skids are essential to ensure compatibility with high-blend sustainable kerosene, as outlined in the technical framework. Compliance with ASTM D7566 quality testing protocols is explicitly mandated throughout the transition.
