AWT Ohio nurse tanks 2007–2011: FMCSA/PHMSA want voluntary thickness and pressure tests. We do not haul anhydrous as a product line

What the notice actually said

A farm co-op tendered a tank and called it freight. FMCSA and PHMSA issued a safety advisory on nurse tanks built January 1, 2007 through December 31, 2011 by American Welding and Tank in Fremont, Ohio.

August 23, 2023: a 2009 tank on a farm lot failed catastrophically and “rocketed” more than 100 feet. Follow-up tests showed cracking at head-to-shell joints. 2012 tanks passed in the cited set — do not assume every year is equal; follow the notice.

Prior research and a previous enforcement on 2009–2010 AWT tanks is the backstory. The 2023 rocket event is why the date band widened in the advisory. Periodic inspection is often exempted for this agricultural hardware — which is why the agencies still want visual, thickness, and pressure tests.

This is agricultural anhydrous hardware, not a 53-foot dry van. Read 49 CFR 173.315(m) and the advisory, not our reefer page.

We include this note because shippers mash “FMCSA advisory” into every commodity. A nurse tank is not dry van, not reefer, not flatbed, not conestoga.

What it changes on Monday

PRIDEUSA does not bid nurse-tank anhydrous as a service. Dry van, flatbed, reefer, conestoga. If a farm co-op tenders this, we pass and point at PHMSA and FMCSA.

Freight in a 53-foot box: Get a Quote. Equipment: dry van. This advisory is not our trailer spec.

Do not send this tank to MC# 875229 and call it a commodity we haul. We will say no early rather than after the appointment is on the board.

Confirm current PHMSA text if you own tanks in that year band. We are not your tank inspector.

What we will — and will not — do

We will not haul anhydrous nurse tanks as a product line. We will not treat this advisory as an ELD story or a dry-van spec.

We will pass a farm-tank tender and point at the agencies. That is what we will do. What we will not do is improvise hazmat we do not run.

Freight that fits a 53-foot box: +1 (847) 702-8181. Human on the desk. The tank stays with PHMSA.

Short glossary

The jargon, in the order it showed up — no extra theory.

Nurse tank: An agricultural anhydrous ammonia tank on running gear, often exempt from some periodic tests — which is why the advisory exists.
PHMSA: Pipeline and Hazardous Materials Safety Administration — co-issuer.

FAQ

Do you haul anhydrous?

Not as a product line. Dry van, flatbed, reefer, conestoga — not nurse tanks.

Is this ELD?

No. It is a tank-integrity advisory from FMCSA and PHMSA. Different folder on the desk.

2007–2011 only?

That is the band in the advisory. 2012 units in the cited tests passed; confirm current PHMSA text before you assume a year.

Why is it on a freight blog?

So nobody tenders a farm tank to MC# 875229 and calls it dry van. The mash-up is the reason the page exists.
