Clean Air Practices at Ports – EPA Interactive Map

The U.S. Environmental Protection Agency (EPA) Ports Initiative works in collaboration with the port industry, communities, and all levels of government to improve environmental performance and increase economic prosperity. This effort helps people living and working near ports across the country breathe cleaner air and live better lives. The Ports Initiative recently release an interactive map highlighting clear air practices at some of the largest ports around the United States.

The interactive map can be found at:

The Ports Initiative website also includes information on methods for performing an emissions inventory, a toolkit to assist community and port collaboration efforts, information on funding opportunities, and other technical resources.

2019 Port Performance Data from the U.S. DOT

The U.S. Department of Transportation’s Port Performance Freight Statistics Program: Annual Reports to Congress provide summary statistics and detailed analysis for the Nation’s largest container, tonnage, and dry bulk ports. Results from calendar year 2019 are now available online.
Individual port statistics can be viewed through the “Port Profile” link on the main Port Performance website at:
Historic reports from multiple years are available from the National Transportation Library at
These are great resources for anyone interested in port activity, port performance, maritime topics, or transportation infrastructure in general.

By the numbers: port statistics for some of the largest U.S. ports

As intermodal connectors for domestic and international freight, our nation’s ports serve a critical role in numerous supply chains and the national economy. In recognition of this importance, the Fixing America’s Surface Transportation (FAST) Act (P.L. 114-94; Dec. 4, 2015; 129 Stat. 1312) established a Port Performance Freight Statistics Program within the U.S. Department of Transportation: Bureau of Transportation Statistics. The first annual Port Performance Freight Statistics Program report provides descriptive statistics for a group of ports for year 2016, including the top 25 ports in terms of total tonnage, twenty-foot equivalent units (TEUs), and dry bulk tonnage. The report is available to download at

The 2016 Port Performance report used multiple sources, including public datasets featured on Data.Gov. One foundational dataset used in the report is the total commercial tonnage carried on waterways published by the U.S. Army Corps of Engineers – Waterborne Commerce Statistics Center.

Harvesting Grain Data

Author: Marin Kress, Research Scientist, Engineer Research and Development Center, USACE

This Grain Transportation Report: Rail Deliveries to Port dataset from the USDA provides the total number of rail carloads used in weekly grain shipments traveling to ports in five different regions of the country starting in 1994.  The five regions are Atlantic, East Gulf, Mississippi River, Texas Gulf, and Pacific.  In 2008 the dataset started recording cross border rail shipments in to Mexico.  Included with each record is start-of-week date, end-of-week date, and number week of year (1-52).  For users interested in learning about intermodal freight flows, agricultural exports, and how the marine transportation system supports American farmers this dataset is a great resource.

A glossary of terms used in the file is available from USDA at:
