The controls on which ACA mass was granted are kept under regular internal review so that they stay effective, current and true to actual practice; review is how the operator confirms that policies, procedures and instructions are followed and still reflect the business. Reviews run periodically and continuously, including quarterly oversight and a fuller annual assessment, find non-conformances, weaknesses and emerging risks, and ensure prompt corrective action so problems do not recur; review also consolidates mass outcomes into formal reporting, including structured compliance statements, and keeps the system responsive to changes in operations, vehicles or regulatory expectations. Six things are looked for: the operator watches mass data, such as weighbridge records, onboard scale readings or loading plan variances, to confirm that mass controls are applied consistently in daily work; review can detect patterns, such as a vehicle type repeatedly nearing its limit, that call for changed loading instructions or equipment calibration; where limits are exceeded, corrective action goes after the underlying cause, such as wrong density assumptions or faulty weighing gear, rather than simply blaming the loader; reviews happen at intervals suited to the risk and scale of the operation, and routine operational reconciliations may serve as that oversight; the operator can show that changes made after a review, such as a revised loading plan, have kept mass compliance on track; and significant changes to mass procedures are documented and communicated so the system stays relevant as vehicle configurations or freight types change.
