Richard Vincent of Associated General Contractors of Kentucky and Daniel Runha of Caterpillar, Inc. stand in front of the newly installed replacement engine on this grader. Coordination throughout the project was significant in contributing to the positive impact of the Kentucky Clean Diesel Project.

In addition to replacing engines and installing after-treatment equipment on vehicles, the Kentucky Clean Construction Project emphasized the value of reducing idling. Here are two of the 100 banners displayed at construction sites throughout Kentucky as a part of this successful project.

The large number of construction companies in Kentucky promoting idle reduction is evidence that it is a good business practice. Turning off the engine whenever possible saves the company money by reducing fuel use and results in reduced emissions for workers at the site as well as the surrounding community.
