Yup,
We had a tank car full of old cooking oil that had the steam pipes inside it rot away from age…
Because you don’t cap the inlet or outlet on the steam heating pipes, when our switch crew kicked the car, the pipe inside the tank broke or ruptured.
Over half of the contents of the car poured out in a matter of minutes.
The EPA made us remove the ballast, ties, and in some places over 12 inches of roadbed material, and have it hauled away in dumpsters that were tarped and labeled hazardous waste.
Seems if this stuff gets in a watershed or aquifer, it can cause all kinds of problems, not the least of which is it can kill aquatic plant life.
If it is allowed to stay in a stream or lake, it will “sheet out” and can block the sunlight from reaching the bottom plants…you get pretty big fish kills and big algae beds will form, robbing the oxygen from the water.
And if it is allowed to remain in, say soil, it disrupts the normal organic life, attracts predatory insects, and in some instances, can kill birds that ingest the insects that are feeding on the spilled oil.
Like the DDT problem, where the toxin was in the insects the birds fed on, and then it caused the thinning of the bird egg shells, ingesting the insects that are feeding on the oil introduces the oil into the birds system, and they are not designed to ingest most of the fats in the oil.
It disrupts their digestive process, and they end up starving to death.
