In 2020 the U.S. government through the Environmental Protection Agency (EPA) committed $300 million in The United States Mexico Canada Agreement (USMCA) trade agreement to identify infrastructure solutions to mitigate the transboundary pollution.

In time the projects have been narrowed down to three, which were presented during the last virtual public information meeting on Aug. 6.
