Business Editors

COLUMBUS, Ind.--(BUSINESS WIRE)--April 16, 2003

Cummins Inc. (NYSE:CUM) today commented on the Environmental Protection Agency's (EPA) notice of proposed rulemaking (NPRM) for non-road diesel emission levels, to take effect beginning in 2008. The proposed rule regulates the exhaust emissions of diesel-powered engines in construction, agricultural and industrial equipment.

Cummins, the leader in emissions reduction technologies, is committed to working toward a cleaner, healthier and safer environment. Since off-road engines were first regulated in 1996, Cummins has reduced oxides of nitrogen (NOx) and particulate matter (PM) by more than 50 percent. In March 2002, Cummins announced its plans to introduce engines beginning in 2005 that will further reduce NOx emissions by an additional 25 percent from unregulated levels. The proposed ruling will reduce emissions from unregulated levels by over 90% when fully phased in by 2014.

"We recognize the challenges of meeting the standards as proposed, and will continue to work closely with the EPA to ensure that the needs of our customers will be met while achieving these standards," said Christine Vujovich, Vice President - Marketing and Environmental Policy. "Cummins is uniquely positioned to apply the right technology for each of the markets we serve," added Vujovich.

Cummins was the first to certify a compliant engine for the strict October 2002 on-highway emissions standards, and now has accumulated over 71 million miles of real-world service hauling freight. These proven engines are being widely accepted as the best technology solution at the new standards. For non-road engines at the 2006 standard, Cummins will use in-cylinder combustion technologies to provide the best customer value in these markets.

The success of these products in providing the best customer value while meeting emission standards is the foundation for achieving the proposed non-road standards. In addition, Fleetguard Emissions Solutions, a Cummins subsidiary, is the leading provider of integrated aftertreatment technologies, further expanding the range of technologies available to Cummins.
