The Authority will provide checker-foreman to check cargo discharged from a vessel and, at the discretion of Terminal Management, the Authority will also provide checker-foreman to supervise the release of cargo loaded, during both straight time and overtime hours. The charge for each checker-foreman will be based on the current labor rates in Rule 34-630, subject to a one (1) hour minimum. The charge will be billed to the Ocean Carrier or its agent unless otherwise approved by the Authority. The Authority reserves the right to provide as many checker-foreman as deemed necessary to protect its interest.
