## Synthesized answer (unofficial)

UFM 3-460-03 is a Unified Facilities Manual providing non-mandatory, informational guidance on petroleum fuel systems maintenance [UFM 3-460-03 Foreword]. It is "For Information Only (FIO)" and exists to help users understand and apply UFC requirements; only UFC establish enforceable requirements [UFM 3-460-03 Foreword].

The document addresses secondary containment for petroleum fuel systems and components as required by UFC 3-460-01, including earthen berms, containment paving, spill kits, and liners [UFM 3-460-03 2-6.2]. Containment areas must be drained frequently to maintain clean, dry, and accessible conditions, with debris removed from drainage inlet grates after each draining [UFM 3-460-03 2-6.3].

For operation and maintenance requirements, consult the applicable Supply Chain Partner (SCP) as defined in DoD 4140.25-M, Volume 1, Chapter 1, Section C1.3.1.5 [UFM 3-460-03 1-6]. Inspection and maintenance must meet the most stringent of UFC, Military-Specific requirements, and applicable host nation, Federal, state, and local codes [UFM 3-460-03 1-6].
