Instead, Paraquat's a toxic chemical.

That means it's regulated by something called the Toxics Release Inventory, which basically is this publicly available database where a little over 600 different toxic chemicals are tracked just to keep people informed.

So it's not saying how much you're allowed to release, but a community can look up what's around them and what chemicals are being released in the air.

So I was able to see all the releases of Paraquat that have been reported in the last about 10 years.

And this facility in Waynesboro, Mississippi, is way out above the rest and the amounts that it is emitting.

So I'll give you a little bit of comparison.

If you're a farmer and you want to treat an acre of your farm,

you'll use about a pound of paraquat.

Other places that handle paraquat, they have released between like one and five pounds of paraquat into the air in the last five years.

The Waynesboro facility in 2024 released 47,000 pounds of paraquat into the air.

That is a crazy amount of paraquat that is being released into the air as a fugitive emission.

We don't have more information about that, unfortunately.

I reached out to the company, which is called Sipcam Agro, as well as the plant manager, to try to learn a little bit more about why so much of this Paraquat was going into the air.

But all we can see is that these are reported as fugitive emissions, which generally means that it's not a deliberate part of the process that's coming out of a smokestack.

And it's an estimate as well.

So this is probably based on some information they have about the

repackaging process.

But the actual numbers could be higher or lower.

Is it legal, Delaney?

It is legal.
