Benefits of Barging
As a normal course of our business, Tidewater handles grain, refined petroleum products, wood and wood products, both liquid and dry fertilizers, and freight of all kinds loaded into containers. We also provide a variety of harbor services, including ship assists. However, as depicted in the accompanying photos, Tidewater also has boats, personnel, and specialty barges that are capable of accommodating a wide range of transportation needs over the full length of the Columbia-Snake River System. |

How Barging Compares with Rail and Truck
This chart summarizes how barging compares to the rail and truck modes of transportation in terms of fuel efficiency, the number of units of production required to move an equivalent amount of freight, and the resulting impact each mode has on the environment.

| (1) | These are the miles one ton of cargo can be transported on one gallon of fuel. |
| (2) | One barge can transport 3500 tons of cargo. That is equivalent to 120,000 bushels of wheat or 1 million gallons of fuel. |
| (3) | One tow, consisting of a boat and four barges is 650 feet in length whereas 480 trucks spaced evenly with 150 feet between trucks is 20 miles in length. |
| (4) | Eastman Data Emissions Comparison: This is the ratio of emissions for trucks and rail as compared to a four-barge tow on a ton-mile basis. So, for example, trucks emit 74.4 times the Carbon Monoxide of a four-barge tow on a ton-mile basis. |
