​Great Lakes Legacy Act

A U. S. sediment cleanup program of the Great Lakes Restoration Initiative
In the 1980s, the United States and Canada created a list of the 43 most environmentally degraded rivers, harbors, and lakes in the Great Lakes region. The Great Lakes Legacy Act (GLLA) is the United States' mechanism for accelerating sediment cleanups in these Areas of Concern (AOCs).

As of 2022, the GLLA program has leveraged approximately $460 million of nonfederal funds matched with about $740 million from EPA to clean up 6.2 million cubic yards of contaminated sediment through 32 different remediation projects. More than 150 acres of upland, shoreline, and underwater habitat have been restored as part of the sediment cleanups, giving ecosystems a boost. 
GLLA projects provide significant  economic, social, and environmental benefits in AOCs. In fact, the Great Lakes Restoration Initiative yields $3.35 in economic activity for every $1 spent through increased property values, tourism, recreation, fishing and more. ​

"You all have a common objective to get the work done right, to get it done quickly, and to get it done cost effectively.
​And with the government contributing a substantial amount for the project, it seems to catalyze the groups to move quickly,
to cooperate, and to act very collaboratively... any time you speed up the process you save money.

- John Morris, Honeywell International, Inc.

"​We could achieve our remediation goals with federal cost-share money that we did not have available in our own state funding…
We can perform more robust cleanups and achieve great things with these partnerships."
