St. John the Baptist Parish
A refinery this size does not sit next to a small town by accident
Three facilities are filed to this town and one of them is enormous. Marathon Petroleum states the refinery here at a capacity of 617,000 barrels per calendar day as of the start of 2026, and describes it as the third-largest refinery in the United States by capacity.
Beside it sit two liquid bulk terminals — one operated by MPLX 0.24 miles from the centroid and one 1.07 miles out — and a petroleum port berth 2.53 miles out. The port district those berths belong to spans 54 miles of the Mississippi River across three parishes.
The tonnage ranking is contested, and the page says so
That district is often described as first in the United States by tonnage, and it is worth being careful with. Regional economic development sources rank it first; other compilations put Houston first and place it second for 2023.
So the ranking is contested and no single figure is adopted here. What is not contested is the scale of the thing next door, and that is what sets the truck work: a refinery of that capacity plus terminals a quarter of a mile away generate continuous tank, freight and contractor traffic rather than seasonal peaks.
It also means the gates are the constraint. Along 54 miles of river district the difference between a good day and a wasted one is usually access, not distance.
Louisiana weight law
The axles under it change the number
Payload is the whole argument on a lane like that, which is where the permits come in.
Louisiana does not write one gross figure and stop. Under La. R.S. § 32:386 a combination that carries a tridem or a quadrum axle may run to 88,000 lb on a state-maintained highway, and the interstate system is carved out of that allowance. The condition is the vehicle’s own configuration rather than its cargo or its route — more axles under the load, more gross on top of it.
The harvest permits sit above that again. Off the interstate the harvest-season permit reaches 86,600 lb under the same section; on the interstate a separate permit under La. R.S. § 32:387 reaches 83,400 lb, for farm and forest products in their natural state along with cotton seed moving from the gin to the mill, raw sugar from the mill to the refinery, and brewer’s grain. Sugarcane runs on its own permit to 100,000 lb, and that one has a hardware condition: the trailer carries an additional single axle, six for the combination, so a five-axle rig does not qualify however it is loaded.
Most states that grant a heavy commodity allowance switch it off at the interstate and leave it there. Louisiana instead writes a second, lower permit that works on the interstate, and 83,400 lb is above the federal figure rather than below it.
La. R.S. § 32:386, § 32:387 and § 32:387.7. Information, not legal advice, and only as current as the date the rule file was last verified.
Louisiana paperwork
We need a title, and the book is named in the rule
Beyond the weight, the paperwork is what decides whether a sale closes this week or next month.
The ordinary case is short: we need a title. If it is lost there is a duplicate, and if the truck is old enough that it never had one there is a route for that too. Neither stops a sale and neither is unusual.
One Louisiana rule is worth knowing before you read anything about a branded title. The total-loss test is written as a percentage of retail value — 75 per cent — and it names the valuation source rather than leaving it open. Most states say “actual cash value” and let an adjuster decide what that is. Naming the handbook makes the threshold something a seller holding the same handbook can check.
Louisiana is a civil-law state and its parishes are not counties with a different name on them. Its lien and title vocabulary does not always map onto the other forty-nine, so a term you were given in another state is worth checking here rather than assuming.
The 75 per cent figure and the named handbook come from a secondary summary of Louisiana total-loss law, not from the section text; the Louisiana rule file records the salvage threshold as not yet extracted from the § itself. Information, not legal advice.
What we buy here
All of that traffic comes to us. Tankers off the Marathon Petroleum refinery and the MPLX terminal racks. Day cabs and road tractors off the Mississippi River district freight. Dump trucks, aggregate haulers and mixers off the turnaround and construction work, plus the box trucks, flatbeds, service bodies and the pickups and work trucks the crews run.
Whichever of those you have, the offer does not change. We buy all of them.
We buy complete trucks. If the engine, transmission, doors, rear ends, drive shafts, wheels or anything under the hood have been removed, we can’t buy it. Small things — a missing bumper — are fine.
Straight answers
The questions we get asked in Garyville
Those are the trucks. These are the things people ask before they call.
- Does it have to run?No. It does have to be complete — if the engine, transmission, doors, rear ends, drive shafts, wheels or anything under the hood have been removed, we can’t buy it. A missing mirror is nothing.
- It is inside the Marathon Petroleum fence. Can you get it?Usually yes, and tell us early. Gate access and escort rules decide what we bring and how long it takes, and knowing in advance saves a wasted trip.
- It hauled petroleum product. Does that matter?Tell us what it carried and whether the tank has been cleaned. It changes what we can do with it, not whether we are interested.
- Will you come out along the river?Yes. We come to you and drive it away, we come to you and tow it, we buy it remotely and arrange the tow, or you drive it to us. St. John the Baptist Parish is a straightforward run for us.
- How far out do you come?All of St. John the Baptist Parish and anywhere along the 54 miles of Mississippi River the port district covers. Distance has never been the problem.
Why people call
Beyond a turnaround ending, the reasons are the ordinary ones. A contract that did not renew when the work finished. A driver who retired. A tanker bought for a Marathon Petroleum project that wrapped up early.
Yards along the river road and out across St. John the Baptist Parish usually have one sitting.
Most of those are not happy reasons and we do not treat them like they are. Somebody wants a straight answer and the truck gone by the end of the week. That is what we are for.
