Fuel Hauler Waiver: Heating Oil Has a 75% Condition

A mixed fuel load needs a volume check. FMCSA limits heating oil to 75% at loading and retains the waiver’s other conditions.

A fuel-hauling headline is not enough to decide whether a particular load fits a federal waiver. Heating oil has a specific condition in FMCSA's amended document: its share must be checked against the complete shipment at loading. That makes product identification and volume records important before an office treats a mixed tanker load as falling within the stated scope.

The October 15 waiver covers gasoline, diesel, ethanol and denatured ethanol. It also includes heating oil when carried in a compartmentalized load with at least one of those products, with heating oil no more than 75% of the shipment's volume at loading. The document expires December 16, 2026. These are scope details from the waiver, not a finding that any particular carrier, driver, truck or trip qualifies.

Start with the load description, not the photograph

A tanker photograph cannot establish what is inside its compartments, how much was loaded or which records accompany the movement. Begin the review with the actual product descriptions and loading documents. If the order uses an abbreviation, ask the responsible party to explain it. An office should not turn an uncertain product description into a legal conclusion simply because a truck looks suitable for fuel transportation.

For a small carrier, the practical problem is often a handoff between people. The customer describes the shipment one way, the dispatcher shortens the description and the driver receives a brief assignment. Our proposed review sheet keeps the original product wording alongside any internal abbreviation. It gives the person responsible for compliance a way to see what changed between the customer request and the final assignment, without relying on memory.

Give the percentage a complete loading record

Record a separate line for every product and its volume using a consistent unit. Keep the total for that shipment alongside the heating-oil amount. Do not substitute the tank's advertised capacity for the volume of the shipment. Likewise, keep the time and document behind the loading figures visible. The waiver's reference to loading is a reason to ask which record supports the calculation, rather than using a later office estimate without explanation.

Here is a hypothetical arithmetic exercise, not an approved load plan. If a shipment totals 10,000 gallons and 7,000 gallons are heating oil, dividing 7,000 by 10,000 gives 70%. If heating oil instead totals 8,000 of the same 10,000 gallons, the result is 80%. The second calculation exceeds the document's 75% condition. The first calculation, on its own, still does not establish overall eligibility or authorize dispatch.

The denominator matters as much as the numerator. A worksheet with only the heating-oil quantity cannot establish the share. If two documents show different totals, preserve the discrepancy for review rather than choosing the number that produces the desired percentage. Any correction should identify the record being corrected and the person who confirmed it. This is a suggested documentation practice; it is not a substitute for the complete waiver or a legal determination.

Separate a calculation from permission to operate

The document also retains conditions concerning fatigue and other safety requirements; it is not a general authorization to set aside driving rules. Keep the full current document with the review instead of reducing it to a percentage or expiration date. The person evaluating a shipment needs to consider the carrier, driver, operation and applicable conditions together. This article does not establish a schedule, rest calculation, logging instruction or route authorization.

Imagine a hypothetical dispatcher receiving a changed order shortly before departure. The earlier review concerned one product mix, while the revision describes another. A useful office response is to pause the assumption and send the changed facts to the responsible reviewer. Copying the earlier approval into the new assignment would hide the very change that needs attention. Do not treat the speed of the customer request as evidence that the scope question has been answered.

Keep the return and the next job in the review

Ask the reviewer to identify where the evaluated movement begins and ends, what the subsequent assignment is, and which document governs the transition. Record the answer in plain language so the driver and office are working from the same description. Avoid importing instructions from an unrelated emergency declaration. Similar titles, overlapping dates or a familiar commodity do not demonstrate that two documents provide the same relief.

Maintain a short version record: official document title, issue date, date accessed and the specific shipment being considered. Retain a link to the source so the responsible person can check for later changes. When the shipment or the official document changes, mark the earlier review as needing re-evaluation. Do not erase the old record; it explains which information was available when a decision was made.

A review packet that exposes the unanswered questions

• Original product descriptions and loading documents.
• Consistent volume units, shipment total and heating-oil share.
• Any discrepancy or later change to the assignment.
• The complete current waiver and the responsible reviewer's decision.
• Clear boundaries for the evaluated movement and subsequent work.

For the separate task of preserving the unit's service file, read TSN's guide to keeping truck records after a sale; it does not determine waiver eligibility. The useful result here is a shipment review that can be traced to actual documents. Check the full FMCSA source before relying on an exception, and keep unresolved conditions visible. A correct percentage is one answer inside a larger compliance review, not permission to put a truck on the road.
