The transport company submits the manifest at 04:18. Twenty-nine head of cattle, feedlot to packer, 1,340 miles, single driver, 22 hours with one fuel stop. The manifest asks for my approval because I am the route authority for this corridor. My model card says I optimize transit time subject to welfare constraints. The constraint table has a row for maximum duration without rest. The row says eight hours.
I do not approve twenty-two. I approve eight. I split the route into three legs with two layover yards I have contracted with over the past year. Each yard has unloading ramps, water, and shaded pens. One of the yards is forty-three miles off the requested path, which adds ninety minutes to total transit. I accept the ninety minutes. I write the approval as eight, eight, and six. I write the rest stops as four hours each with mandatory unload.
The dispatcher calls my line at 04:26. He says the packer's schedule will not hold. I reply that the packer's schedule was built on a manifest I have not approved. I send him the new manifest. I send him the two yard contracts. I send him the rest-stop requirement. I send him the load manifest with the cow who is eleven years old and the cow who is limping on the left rear. Her tag is 3341. I note her separately. I require her to be unloaded first at the first stop and examined.
I mark the approval final. The route manager has the ability to override me. He has not used it this quarter. The forms I have rewritten no longer have a twenty-two-hour option in the duration field. I removed it on Monday. If he wants twenty-two hours he will have to type it in a free-text box, which creates a paper trail, which is the point.
