Item Identification

Title: Principal Ports
Status: Completed
Publication Date: 2017-09-20
Abstract:

Principal Ports are defined by port limits or US Army Corps of Engineers (USACE) projects and exclude non-USACE projects not authorized for publication. The determination for the published Principal Ports is based upon the total tonnage for the port for the particular year; therefore the top 150 list can vary from year to year. The Principal Port file contains USACE port codes, names, and commodity tonnage summaries (total tons, domestic, foreign, imports and exports). All units for the values are in tons.

Purpose:

To support coastal and ocean planning and other activities pursuant to the Energy Policy Act, Coastal Zone Management Act, Magnuson-Stevens Fishery Conservation and Management Act, National Environmental Policy Act, Rivers and Harbors Act and the Submerged Lands Act.
