i think they just meant "quietly" as in not notifying the Nueces County drainage department that a permit was granted in their area.

That must be it. I can see if they are normally published or announced publicly somewhere, then it makes sense but if it's not done for other permits then it's sounds like they are implying nefariousness.

It was probably unceremoniously posted on a website somewhere. Letter of the law satisfied.

Would Eurofins be able to set up monitoring on Tesla's property?

What other sources would have similar pollutants to a Lithium factory? It seems pretty specific and if there was some other obvious source why wouldn't Tesla point that out?

Obviously, discharging "dark and murky" polluted water is bad. But some of the figures from the lab report don't seem that terrible: * Hexavalent chromium at 0.0104 milligrams per liter, just above the lab’s reporting limit of 0.01 mg/L. Hexavalent chromium is classified as a known human carcinogen by the US National Toxicology Program. It is the substance the Erin Brockovich case was built around. * Arsenic at 0.002…

nah, there is no reason they should be discharging any hexavalent chromium, we have better, less insanely toxic ways of chroming things. trivalent chromium is much less toxic, hexavalent chromium should be banned world-wide. what's more, i'm not finding a reason that tesla would need hexavalent chromium in battery production, which leads me to speculate that this is waste from one of their other car factories where t…

This refinery is situated miles away from any other Tesla factories.

That is well below the noise floor. Like the similarly toxic selenium, arsenic is an essential micronutrient in animal biology. It is possible to be deficient in arsenic, though rare in practice. Natural background levels are far higher in many locales with no adverse effects.

I often see trace quantities of arsenic trotted out by the popular media for scaremongering purposes. Examples like the above are an immediate red flag.

> I'm confused, does Tesla have the right to dump water or not? I would assume that this is exactly what a permit is for?

If you have a permit to dump wastewater into a river, you are not allowed to dump your wastewater wherever in that river's basin on the assumption that it will eventually flow into the river. You are supposed to use a pipeline for wastewater transfer.

So, it's fine as long as it's legal, then? How about when it enters the food chain and starts to accumulate? Will the elements say that "we're under legal limits, and accumulate slowly, so we will act nice and don't poison the organism we're in?" Love that way of thinking.

Arsenic and lead occur naturally through the food chain. If the levels of discharge are not significantly above the normal levels (and they aren't) then it's harmless.

They are still not harmless. They are normal. However if they are at all above natural (that is your input levels) you should treat and remove them. It is not unusual for the output of a sewage treatment plant to be cleaner water than what goes into your drinking water system.

How is that a half truth? If you read the article it’s clear that this discharge is fully permitted and legal. All the substances they portray so shockingly were found at barely detectable levels. I read the whole article and I don’t really understand what is being criticized, if not manufacturing itself. Do people think it’s possible to make a massive battery factory with zero industrial waste water output? Or do th…

Not OP but, half truth is here "remains in complete compliance with all requirements of its state-issued wastewater discharge permit" and yet... "Neither hexavalent chromium nor arsenic appears in Tesla’s TCEQ discharge permit as an allowable pollutant." Both which were found in the waste water. The original test did not test for those, so I guess what the guy was saying was true at a time?

The permit also didn’t list strawberry bubblegum. The levels of these pollutants were found to be similar to background levels. Where do you think arsenic comes from?

If the Texas regulators are asleep at the wheel then be mad at them. Businesses are guided by laws, but there’s no allegation any laws were broken. I’m no Tesla partisan but this just feels like mindless ragebait.

If I am reading this correctly, the Erin Brockovich hexavalent chromium was detected in Hinkley at levels of 1.2 to 20 ppb (ug/L). Contrasted here with 10.4 ppb (ug/L). Sounds notable to me if they are regularly flooding the zone with this.

> So, it's fine as long as it's legal, then? > Love that way of thinking. I mean.. yeah, kinda'? We live in a society made up of laws, that's kind of the premise. So if we don't think something is fine, we can make it illegal (and we often do). It's a pretty good way of thinking methinks, what's your alternative?

>I mean.. yeah, kinda'? We live in a society made up of laws, that's kind of the premise.

It might be news to you, but the laws don't dictate what's fine, and what isn't.

Aside from things like slavery being legal and homosexuality being illegal in the past, I'll note that it's perfectly legal for you to drink bleach, but it wouldn't really be fine for you to do that.

(I hope we can agree that advising people to do something "fine" isn't rude, but telling someone to go drink bleach would be) .

> So if we don't think something is fine, we can make it illegal (and we often do).

So, to boot, "it's fine as long as it's legal" doesn't apply to those things, youthinks.

Also, "we" is a peculiar pronoun that needs a lot of expansion, considering that the "we" negatively affected by "not fine" things isn't the same "we" that benefits from them, and it's the latter "we" that has direct influence on legislation.

Some interesting terms to read up on include "negative externality" and "corruption" (assuming youreads).

>It's a pretty good way of thinking methinks, what's your alternative?

If we turn to historical examples, the French Revolution certainly provides an example for alternative ways to resolve disparities between what's legal and what's fine.

There are plenty of others, but that question wasn't asked in good faith, methinks, and so doesn't deserve a more in-depth answer.

> What [the wastewater discharge permit] did not do, explicitly, was grant Tesla the right to use public or private property for wastewater conveyance. The drainage district that manages the ditch the pipe was discharging into was never notified that the permit existed. I find it kinda worrying that so much of the legal weight of this case doesn't seem to be about the untreated wastewater discharge at all but only ab…

Can a big and rich company be fined for some minor technicality? Maybe! If the cost of the attempt is lower than the amount of the possible fine, why not try and find out? This may sound cynical, but this also one of the driving forces that often keep big companies from breaking rules.
