To amend title 46, United States Code, to make certain improvements to the project selection criteria for grants under the port and intermodal improvement program, and for other purposes.

This bill makes emission mitigation projects that support the use of land-based power sources to supply energy to passenger vessels at berth (i.e., shore power) eligible for grants through the Port Infrastructure Development Program.
