>> The U.S. Army Corps of Engineers is dropping its plan to expand a toxic down on Lake Michigan.

It comes after a years long battle with community members.

Environmentalist on the city's southeast side.

Our own Patty.

What Lee joins us now with more on what this means.

Patty, this has been a years long battle as I just first of all, what is this toxic sludge and what were they planning to do with it?

Right?

So toxic sludge.

That's all the sediment that gathers on the bottom.

>> Of like the Calumet River, the cows channel and the Army Corps has been dredging it to keep that channel navigable for shipping.

I could just normally dump that back into the lake, but because it's contaminated with chemicals, pollutants like arsenic, mercury lead.

It needs to place it in what's called a confined disposal facility.

So that already exists right there on the mouth of the Calumet River.

It's been there for 40 years in the Army Corps, wanted to expand it by 20 more feet high and continue dumping the sludge.

There's some people really hold out, right?

Right.

You had with the Alliance of the Southeast, which is a community organization in the Southeast side neighborhood of Chicago, friends of the Parks and the Environmental Law and Policy Center working the start of legal angle for them objecting to it because that community is already overburdened, they say with with dumps with pollution, with industry, friends of the parks had long been promise that once this site maxed out and it's been there for 40 years, been doing so much work.

Great for that.

You they've wanted to lake complete this lakefront path.

That's part of like the last 4 miles and and to put a park there, that was the promise of Army Corps be like we'll shut it down.

Will give you these 45 acres, remediate the site and it'll be parkland for the community.

So they're like you made the promise.

Now you're going back on its back on its way next.

So the issue now is there the Army Corps has withdrawn its plan.

But if they're still going to drudge, they're still going maintain that shipping channel.

Where's this toxic sludge going to go?

And they said they already explored alternate sites and nobody helps wanted this in their community.

So they're going really have to work with state and local officials to find a place to put this stuff on.

doesn't know exactly.

Well, thank you, my or anyone.
