The Oregon Department of Environmental Quality (DEQ) has introduced the Diesel Emissions Identification Program (DEIP), aiming to provide a voluntary emissions control labeling system for nonroad and on-road construction equipment such as excavators, concrete mixer trucks, and dump trucks. This initiative furnishes labels to distinguish the engine exhaust emissions profile for each piece of equipment at construction sites.

Participation in DEIP enables companies to showcase their adherence to state and local regulations concerning emissions from construction equipment. It also serves as a demonstration of their commitment to supporting the well-being of neighboring communities and vulnerable populations.

Rachel Sakata, the manager of DEQ's Transportation Strategies section, highlights the importance of the program in light of Oregon's growing population and the increasing construction activities aimed at enhancing communities. She emphasizes that DEIP offers an accessible means for construction companies to showcase their efforts in reducing harmful emissions, thereby contributing to improved air quality and public health.

The inception of DEIP stems from the passage of HB 2007 by the Oregon legislature in 2019. This legislation was crafted to address the reduction of diesel emissions within the state and mandated DEQ to develop and implement rules (OAR 340-269-0010, Division 269) for a diesel emissions labeling program.

DEQ encourages owners and operators of construction machinery or vehicles to explore the option of applying for Diesel Emissions Mitigation Grants, which can aid them in complying with state and local diesel exhaust emissions standards.
