Terminal Operators and Fleet Owners Best Practices

Terminal operators and managers are the key to a seamless flow of cargo that drives a successful port. Equipment owners and operators have many ways to reduce diesel emissions while maintaining or growing a healthy bottom line.

Establish anti-idling policies

Turning off engines when not in use is the smartest and easiest way to reduce air pollution and save money. Not only does unnecessary idling waste fuel, but it causes wear and tear on the engine which requires more maintenance. EPA's SmartWay program maintains a list of verified idling reduction technologies.

Expand off-peak operations hours to avoid congestion

By extending terminal gate hours beyond the regular schedule or offering incentives for off-peak operations, truck queuing, idling, and traffic congestion are shortened. Not only does this increase flow and efficiency, but reduces the impacts of diesel exhaust during ozone hours.

Retrofit with verified technologies, use cleaner fuels and operate more efficiently

Install emission reduction devices, replace engines or equipment, use cleaner fuels, and implement operational efficiencies which have been tested and verified. These technologies are cost-effective and yield substantial emission reductions. See EPA’s Clean Diesel Technology pages to learn more about available options. Visit EPA's Clean Diesel National Grants for information on grants.
