What Port Authorities Can Do
One of the major issues port authorities are facing today is promoting economic development while protecting environmental quality. Public ports play an integral role in working with private industry to develop and finance marine terminals and facilities, as well as to manage the port. Whether an "operating port" or a "landlord port," public port authorities are key as sponsors of federal navigation projects that benefit all maritime interests.
Establish anti-idling policies
By establishing an anti-idling policy for trucks, locomotives and cargo handling equipment, diesel emissions can be effectively reduced. 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 idle 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 or require installation of 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 Technologies and Verification pages to learn more about available options. Visit EPA’s Grants & Funding pages for information on grants.
Develop an Environmental Management System
Ports across the globe are adopting Environmental Management Systems (EMS) as a way to plan for continuous improvement in environmental performance. For more information, see An Environmental Management System (EMS) Primer for Ports: Advancing Port Sustainability (PDF) (50 pp, 1.4MB, April 2007, About PDF).
Develop an emissions inventory
An emissions inventory is necessary for port authorities to understand and quantify the air quality impacts of current port operations. Ports are major contributors of NOx, PM, SOx, and air toxics. Emissions inventories help to assess the impacts of port expansion or increased activity and provide a baseline for developing emission mitigation strategies and track performance over time.
A number of port authorities have already performed emissions inventories and are taking advantage of emission reduction opportunities. For more information on emissions inventories, see the Current Methodologies in Preparing Mobile Source Port-Related Emission Inventories (116 pp, 300MB, April 2009, About PDF) report.
Develop educational programs on air pollution and emissions reductions for terminal operators and fleet owners
One barrier to implementing cost-effective emissions reduction strategies is lack of knowledge on the part of terminal operators and fleet owners about various options. Guidance and education on air quality, air pollutants, technologies and ways to implement emissions reduction strategies not only increase awareness but also increase the opportunities reduce emissions. EPA has useful publications on these topics.
Substitute electric power for diesel power
Using electric shore side power at berth or "cold ironing," rather than running auxiliary diesel engines is effective for ports and vessels that have long hoteling times, multiple annual vessel calls, and high auxiliary power needs, such as cruise ships.
Substitute rail or barge for trucking
Using rail or barge instead trucking increases the volume flow and efficiency of cargo in and out of the port. Rail and barge offer less congestion than trucks and reduces diesel exhaust from unnecessary idling.
Contact state environmental agencies for additional funding opportunities
California’s Carl Moyer Program and Texas’ TERP Program offer grants for activities that reduce diesel emissions. Check to see if your state or local government might offer financial assistance for clean diesel projects. Visit EPA’s Other Funding Sources for additional information.
