The Kenworth assembly plant in Renton, Wash., was recently honored with a 2011 Gold Award presented by the King County (Wash.) Industrial Waste Program.

The award is for compliance with the plant's industrial wastewater discharge permit. The award recognized the plant for one year of no wastewater violations of any kind covering discharge, permit, ordinance, reporting, self-monitoring, and King County monitoring.

"The Kenworth - Renton plant has a comprehensive environmental stewardship program that produces excellent results," said Daryl Simon, Kenworth - Renton plant manager. "Our dedicated employees work hard to produce high quality Kenworth trucks and also take our environmental initiatives very seriously. The 2011 Gold Award from the King County Industrial Waste Program is recognition of their efforts in the environmental arena."

Kenworth's plants in Renton, Wash., and Chillicothe, Ohio, both hold ISO 14001:2004 certification for effective environmental management systems established to help build Class 8 trucks in an environmentally sustainable manner. Kenworth's medium-duty products are produced at the Paccar manufacturing facility in Ste. Therese, Que., which also holds ISO 14001:2004 status.
