View Full Version : Trailer Mounted Fuel Tank - Regs/Rules??

09-01-2007, 02:05 AM
Building a new trailer for my Bobcat(skidsteer) and I am wanting to mount a auxillary fuel tank on it, about 75 gallons capacity. I read a number of forums and it seems that on one of them, there was a discussion about the Federal and /or State regulations governing the capacity, etc. Figure a lot of you are probably knowledgeable about this, so hoping for some input. Located in Georgia. Any help greatly appreciated.

In Alabama I believe as long as the capacity is under 105 gallons you don't need a hazmat permit. There might be different regulations if you mount the tank to a trailer I believe these are for truck mounted fuel tanks. We use fuel tanks mounted in the bed of our pickups.

Thanks, Adam. Yeah, it makes more sense to mount the tank on the truck, but at this point, a larger truck just isn't in the picture and I just don't have the room on the truck. Most likely there will be different regs for a trailer mounted tank.

I tried to look up something on this on the dot.gov website, but it is about useless as a source for information. :dizzy: Ran out of time but you might be able to find something online. Basically I would think you just need to know the "reportable quanitity" or RQ for diesel fuel. Stay below that amount and you should not need any hazmat placards or license.

I do see guys with 100 gal tanks strapped on their tag trailers from time to time. I considered doing that when I was running a dump truck to pull my machine all the time, but now I've got a pickup with 8' box; plenty of room for a tank in there.

110 gallons in MI. Pretty sure that is nation wide (federal regulations). Ill look in my hazmat book in the morning.

Found this on another forum:
(from http://www.truckstopusa.com/forums/viewtopic.php?t=12046&sid=db6411394f9aa56c8c7991e27c36269a, about three or four posts down.)

It's a quote from some regs somewhere; looks like it is referring to extra fuels carried as reserve fuel or material of trade, which I think is what a transfer tank carries. I'm not an expert but it may be a place to start...

§392.51 Reserve fuel; Materials of trade.

Small amounts of fuel for the operation or maintenance of a commercial motor vehicle (including its auxiliary equipment) may be designated as materials of trade (see 49 CFR 171.8).

(a) The aggregate gross weight of all materials of trade on a motor vehicle may not exceed 200 kg (440 pounds).

(b) Packaging for gasoline must be made of metal or plastic and conform to requirements of 49 CFR Parts 171, 172, 173, and 178 or requirements of the Occupational Safety and Health Administration contained in 29 CFR 1910.106.

(c) For Packing Group II (including gasoline), Packing Group III (including aviation fuel and fuel oil), or ORM-D, the material is limited to 30 kg (66 pounds) or 30 L (8 gallons).

(d) For diesel fuel, the capacity of the package is limited to 450 L (119 gallons).

Hey guys, I really appreciate all of the input.

If I'm reading the rules correctly, then I've got a problem as I need to carry gasoline. All 3 of my machines and both of my trucks, are gas units and the 5 gallon can routine is not only aggravating, it's wasteful. I would like to mount about a 50 -60 gallon tank, w/electric pump, which would cover me for several days. Not to mention the small fact, that a lot of the areas I work, you don't leave a 5 gallon can sitting around w/gas in it, cause it will be gone, in short order. Stopping for gas every morning, also consumes a lot of time and this would allow me to fill up on the site. Somewhere, I read, can't remember where, that a fellow was ticketed by the DOT for having over a certain amount of fuel, or tank size, don't know which. Additionally, I believe he had diesel fuel, which according to the regulations posted above, you can carry more of than gasoline. So ?????:confused:
