This Act is water infrastructure legislation that deals with ports, levees, and environmental protections, among other water infrastructure issues. New water infrastructure legislation has not been passed since 2007, and the House and Senate, in this bill, have agreed to legislation that is earmark-free. The original Senate version of the bill is here; it’s since been amended, and now the House and Senate have matching legislation. Notably, the bill de-authorizes $18 billion worth of projects that were greenlighted in the 2007 bill but never implemented.
The House Committee on Transportation & Infrastructure offers a print overview and a ~2 ½ minute video explaining the bill here. The video is narrated by Senator Chuck Schumer (D-NY). (No mention of whether or not he is also illustrating.)
