Tetra Tech has assisted clients in clean truck program (CTP) design, development, and implementation by replacing tens of thousands of trucks with clean, energy-efficient models. This program retires old polluting diesel trucks and replaces them with cleaner trucks that meet U.S. Environmental Protection Agency (EPA) 2007 heavy-duty truck emissions standards. The overall program supports sustainable goods movement and achieves greenhouse gas (GHG) emission reduction. 

In collaboration with regional stakeholders, the Port of Los Angeles (POLA) and the Port of Long Beach (POLB) developed the San Pedro Bay Ports Clean Air Action Plan. The plan’s CTP aimed to reduce truck-related air pollution by 80 percent by 2012 and rapidly modernize the drayage fleet without disrupting commerce. In 2008, POLA and POLB (San Pedro Bay Ports) selected Tetra Tech as their concession and grant administrator to implement the CTP.

The CTP used a phased approach to replace approximately 16,000 old drayage trucks that served the ports. To replace the trucks by 2012, the CTP instituted a concession program and provided grants from the POLA, the POLB, and the State of California. Key program elements included:

  • Implementing the POLA and POLB’s Proposition 1B funding program
  • Implementing automatic vehicle locator tracking for program compliance
  • Implementing clean diesel engine compliance and retrofit requirements
  • Developing and implementing a web-based drayage truck registry
  • Developing and implementing grant processing and monitoring
  • Developing concessions and administrating all drayage truck operations seeking access to port terminals
  • Preparing an alternative-fuel drayage fleet plan
  • Conducting public outreach programs targeting key stakeholders
  • Establishing multilingual truck assistance at the terminal access center and on the toll-free helpline 

Implementing the CTP has resulted in the world’s lowest-emissions drayage fleet. As of July 2014, we have met our goal of replacing 16,000 drayage trucks with clean, energy-efficient versions that are serving both ports; all of which meet or exceed the 2007 EPA emission standards. More than 900 are fueled by natural gas, and more than 3,200 are 2010 EPA emission-compliant trucks. We have helped reduced CO2-equivalent emissions by approximately 90,000 metric tons. The POLA and POLB awarded contract extensions to Tetra Tech as a result of our on-time and under-budget performance during the development, implementation, and administration of the CTP.
