Re: Virginia Beach Tragedy-Contractor...

Man, I had the exact same thought tankgenie. I too am from VB (graduated from Kellam in 1970) and was saddened to see this. That was a great place in the 60's (and 70's).

Re: Tank Warranty Voided

I did have a South San Francisco city inspector ask me once if I had compacted the pea gravel before final grade. I was speechless with inspectors at that point. You can't compact pea gravel, but ... you can consolodate it. If you have a chance, take a 5 gallon bucket, use the backhoe to dump pea g...

In my opinion the tech and the site were both culpable.
I would say the tech and the driver of the fuel truck are culpable, but I'm on the fence as to whether the site is. Of course I bet the site is responsible to the authorities.

Re: Your thoughts on culpability

The pipe stub is higher than the top of the tank. Has to be for suction to work. Tank was overfilled. Maybe yes, maybe no. That suction line was open to the atmosphere. A 4" drop and 2" vent creates some pressure in the tank. If there was a pressure/vacuum vent even more (yes, I've seen them on ker...

Re: Your thoughts on culpability

The bottom line is the driver over-filled the tank. The dispensing pump does not exist to contain an overfill. Some other system failed that allowed the release. Either the drop tube shut off failed, or the overfill alarm failed. IDK, .. 1 PSI will equate to about 28" water column, since the specif...

Venting sumps to the canopy. This is not an April fools joke or question is it?
No, but I can understand this question, :lol:

I heard about this about a month ago. Your comment about vapor leaks on the tank is a good one (early post).

Re: Your thoughts on culpability

Why he was unable to get his wrench? How about using a coat hanger, or just reach your arm into it? My thought was a trash bag could have kept the arm dry and allowed grabbing of the wrench. This is of course Monday morning quarterbacking. He left the site with a very good chance of having a disast...

Re: Your thoughts on culpability

….. he is entirely at fault, as even if the tank is overfilled, that check valve must be well below the level of the fill to have shot up from the suction stub. I think he has culpability, but I disagree that the broken check valve needs to be below the level of the fill for a spill to occur. The l...

It sounds feasible. But would this then have to be regulated by the local Air regulators, much as a stage II vapor recovery system is?
That is an excellent question (one I did not think to ask that project manager).
