When are permits required for fueling and aircraft-refueling vehicles?

If you operate aircraft‑refueling vehicles you must get an operational permit (the code points you to the permit chapter in **§2001.3**) and follow the dispensing, transfer and storage rules in Chapter 20 and Chapter 57 per **§2003.5**; Chapter 57 adds explicit permit and site/plan requirements for on‑demand/mobile fueling.

What the code requires — plain English (controlling §)

  • You must obtain an operational permit to operate aircraft-refueling vehicles; the code directs permit questions to the general permit rules (see §2001.3).
  • All dispensing, transferring, and storage of flammable and combustible liquids at aviation facilities must follow Chapter 20 and Chapter 57 (so permitting and operational controls in those chapters apply) per §2003.5.

The single most important rule: if you will operate aircraft‑refueling vehicles you need an operational permit (see §2001.3) and must follow the dispensing/transfer rules in Chapter 20 and Chapter 57 (see §2003.5).

Requirements in detail

Permit trigger — aircraft-refueling vehicles

  • The specific trigger is concise: permits to operate aircraft‑refueling vehicles are governed by the general permit provisions (the code points you to the permit chapter). See §2001.3.
  • Because §2003.5 requires dispensing/transfer/storage to be done “in accordance with this chapter and Chapter 57,” many operational details and additional permitting requirements for mobile/on‑demand fueling appear in Chapter 57 (examples below).

What “in accordance with this chapter and Chapter 57” means for permitting/operation

  • Chapter 20 (Aviation) contains operational requirements for aircraft fueling equipment, personnel, bonding, emergency shutoff, spill procedures and training (for example, §§2006.3–2006.13 and related).
  • Chapter 57 contains the mobile/on‑demand fueling rules and explicitly requires operational permits for mobile fueling operations of motor vehicles (e.g., §5707.1.1).

Decision-relevant dimensions (quick reference table)

Activity / trigger Permit required? Key operational constraint(s) to check Code reference
Operate an aircraft‑refueling vehicle Yes — see general permit provisions via §2001.3 Must follow Chapter 20 operational rules (bonding, attendance, shutoff, etc.) §2001.3 ; see Chapter 20 (e.g., §§2006.*)
Dispensing/transfer/storage at aviation facility N/A as separate phrase — must comply with chapter rules; may require permits under Chapter 57/105.5 Chapter 20 + Chapter 57 controls (bonding, spill plan, emergency procedures) §2003.5
On‑demand mobile fueling of motor vehicles (non‑aircraft) Yes — operational permit required Must submit safety/response plan; operate only at approved locations (§5707.1.1) §5707.1.1
Hydrogen on‑demand mobile fueling Yes — permit & approval required Special hydrogen limits, emergency plan, approved locations (§5809.1.1) §5809.1.1
Site/location separations for mobile fueling Permittees must comply with separation rules in Chapter 57 Typical required separations: 25 ft, 15 ft, 10 ft (see relevant sections below) See §5707.4.1 and §5706.5.4.5

(Always review the permit chapter referenced by §2001.3 and the specific Chapter 57 sections that apply to the kind of mobile/on‑demand fueling you plan to do.)

Exceptions & special cases

  • The code text in §2001.3 is brief and directs you to the permit rules; local fire authorities implement permit details (see §105.5 as referenced by §2001.3).
  • Chapter 20 includes operational exceptions (for example, aircraft‑fueling vehicles may be located under turbine‑engine aircraft wings during underwing fueling — see the specific exception in the Chapter 20 fueling rules). These operational exceptions do not eliminate the need for permits where §2001.3 applies.
  • Mobile/on‑demand fueling has tailored separation and location exceptions. For example, a storm‑drain distance requirement may be waived if an approved cover or equivalent is in place; review the applicable Chapter 57 exceptions when planning operations.

Common mistakes

  • Assuming that because fueling occurs at an airport it is automatically exempt from permits — §2001.3 still directs permitting for aircraft‑refueling vehicles to the permit rules. Obtain permits rather than relying on assumptions.
  • Confusing aircraft‑refueling vehicle rules with on‑demand mobile fueling for motor vehicles — Chapter 20 governs aircraft fueling operations, while Chapter 57 contains separate mobile/on‑demand fueling permit and site rules (both may apply depending on the activity). Check both §2003.5 and the Chapter 57 sections.
  • Overlooking required supporting documents for permits — Chapter 57 requires an approved written safety and emergency response plan and training/records for mobile fueling permits. Missing those is a common reason for permit denial.
  • Neglecting required operational controls listed in Chapter 20 (bonding, attended operations, emergency shutoff testing, spill notification). Even with a permit, failure to comply with these is a violation.

Worked example — concrete scenario

Scenario: A fixed‑base operator (FBO) will operate two aircraft‑refueling vehicles to service piston and turbine aircraft at an airport. The FBO also wants to run a separate mobile fueling service that will top off staff cars in the employee lot.

  1. Aircraft‑refueling vehicles: Because the activity is operation of aircraft‑refueling vehicles, an operational permit is required as directed by §2001.3. The FBO must apply under the permit provisions referenced by §2001.3 and comply with Chapter 20 operational requirements (bonding, attendance, emergency shutoffs, spill procedures).

  2. Mobile fueling of staff cars: This is an on‑demand mobile fueling activity for motor vehicles. Chapter 57 requires an operational permit for on‑demand mobile fueling (§5707.1.1). The FBO must submit a written safety and emergency response plan and follow separation rules. For example, the point of connection for mobile fueling must not be within 25 feet of buildings/lot lines (see §5707.4.1) and mobile fueling vehicles shall not park within 10 feet of buildings/lot lines while fueling. The FBO must also ensure fueling does not occur on public streets or inside buildings.

Practical numbers to check before the permit application:

  • Maintain at least 25 ft from buildings/lot lines for the point of connection when conducting mobile fueling (Chapter 57 rule).
  • Ensure aircraft‑refueling vehicle operations comply with the 10 ft minimum clearance from aircraft vent openings and maintain bonding and attendance per Chapter 20 fueling requirements.

Related provisions (use these sections when you prepare the application or operations)

  • §2001.3 — Permits: directing permit needs for aircraft‑refueling vehicles.
  • §2003.5 — Dispensing/transfer/storage must follow Chapter 20 and Chapter 57.
  • §2006.5.1 – §2006.6 (Chapter 20 fueling operations) — Positioning, bonding, attendance and emergency shutoff rules for aircraft fueling.
  • §5707.1.1 — On‑demand mobile fueling operations: operational permit required; location and plan requirements.
  • §5707.4.1 and §5706.5.4.5 — Separation and location limits for mobile fueling operations (25 ft, 15 ft, 10 ft guidance depending on the operation).
  • §5809.1.1 — Hydrogen mobile fueling: explicit permit & approval requirement and special hydrogen limits.

(When in doubt, start with §2001.3 and §2003.5 and then pull the specific Chapter 20 or Chapter 57 sections applicable to your exact fueling scenario.)

Frequently asked questions

Do I always need a permit to fuel aircraft at an airport?

Yes — §2001.3 directs that permits to operate aircraft‑refueling vehicles are handled under the permit provisions (see the permit chapter referenced by §2001.3). You must also comply with Chapter 20 operational rules.

If I only top off company cars on airport property, is that covered by the aircraft‑refueling vehicle permit?

Not necessarily — topping off motor vehicles is an on‑demand mobile fueling activity governed by Chapter 57. Chapter 57 requires an operational permit for mobile fueling (see §5707.1.1). Check both Chapter 20 and Chapter 57 for overlap.

What documents are commonly required with a mobile fueling permit?

Chapter 57 requires an approved written safety and emergency response plan, training records, and, where required, a detailed site plan showing buildings, drains, and how spills will be contained. See §5707.3 and related subsections.

Where can I find the specific permit application rules referenced by §2001.3?

§2001.3 points to the general permit chapter (Section 105.5) for permit application procedures and the local fire code official enforces them. Review Section 105.5 and consult the local fire code official for application requirements.

Are there special rules for hydrogen mobile fueling?

Yes — hydrogen mobile fueling has a separate permit and approval requirement in §5809.1.1, and it imposes special limitations and documentation requirements specific to hydrogen.
