ULO feedstock quality checklist

Compare the consignment ID, vehicle, compartment, container and seal details.

Record the source location, responsible organisation and supporting authorisation where applicable.

Check the transporter, transfer document, collection date, quantity and handover acknowledgement.

Record the oil family, source process and previous cargo or container contents. Treat unknown as unresolved.

Record its version, effective date, jurisdiction and responsible approver in the evidence notes.

Confirm that used oil, hazardous waste, solvent, coolant and other legal categories have not been treated as interchangeable.

Check applicable permits, registrations and route restrictions before movement or receipt.

Acceptance must be route-specific. A rejected load still requires a lawful destination.

Record jurisdiction-specific requirements without copying generic thresholds into the facility profile.

Treat flash point as a screening property, not as identification or quantification of fuel contamination.

Unknown source history or solvent use remains unresolved until the applicable classification and analysis are complete.

Record known mixing, visible phase separation and the basis for any required confirmatory testing.

Apply the current jurisdictional requirements and competent analysis where the source could present PCB risk.

Consider brake fluid, acids, alkalis, pesticides, metalworking fluids and other materials outside the accepted-source list.

Record leaks, structural defects, temperature concerns and any incident response.

Record free water, sludge, sediment, phase separation and unexpected appearance. Odour is an observation, not an acceptance test.

Confirm capacity, tank identity and compatibility with the declared source.

Check secondary containment, connections, unloading controls and the applicable site procedure.

Do not commingle an unidentified, unsampled, unresolved or quarantined load.

Confirm that the selected practice covers the material and container type.

Record mixing or circulation, sample points, free water, sediment and the reason for any composite.

Record containers, labels, seal numbers, storage conditions and retention period.

Record the sampler and every transfer to the receiving laboratory or retained-sample store.

An accreditation certificate alone does not show that the required method is within scope.

Record limitations, invalid samples, substitutions, detection limits and unresolved uncertainty.

Record the receiving tank, treatment, quarantine condition, return or authorised alternative destination.

Record the reviewer, role, date and decision basis below. Do not use a checklist count as approval.

Preserve the original status, retests, overrides, corrections and final physical disposition.
