Mack Trucks Lehigh Valley Operations

The entire line of Mack class 8 trucks is assembled in the 1.3 million square foot Lehigh Valley Operations (LVO) assembly plant. The manufacturing location is certified to the internationally recognized ISO 9001 standard for quality and ISO 14001 standard for environmental management systems. 

The LVO facility is also a model for energy efficiency improvements. In 2013, the plant became the first site to earn the U.S. Department of Energy’s Superior Energy Performance® (SEP™) Platinum certification in the Mature Energy Pathway.

The SEP program certifies industrial facilities that implement an energy management system that meets the ISO 50001 global energy management system standard, in addition to achieving improved energy performance as verified by an independent third party auditor.
