Cummins Power Generation Announces Tier 4 Final Readiness three years ahead of EPA deadline, Receives EPA Tier 4 Interim Certification Across 680–2,750 kW Generator Set Range

Aug 9, 2012

MINNEAPOLIS — Cummins Power Generation Inc., a division of Cummins Inc. (NYSE: CMI), announced today the company’s entire stationary diesel generator set range from 680–2,750 kW, including the industry leading Mission Critical 2500 kW diesel generator set, has received Environmental Protection Agency (EPA) Tier 4 interim (Tier 4i) certification for the North American market.

“Cummins has been a leader in developing technologies that meet all emission regulations ahead of their implementation dates,” said Tony Satterthwaite, Vice President, Cummins Inc. and President, Power Generation Business. “I am delighted to announce that our Tier 4 interim certified generator sets are Tier 4 Final ready and fully capable of meeting the most exacting EPA requirements three years ahead of schedule. Our customers’ operational flexibility is further enhanced with a clear roadmap to meeting EPA Tier 4 Final requirements in 2015.”

EPA mandates that all non-emergency applications be Tier4i certified. Nonetheless, in certain locations, the local ordinances may require that emergency backup generators also adhere to stricter emissions limits. Because Cummins’ stationary diesel generator sets can be configured to meet requirements beyond Tier 4i if necessary, Cummins generator sets are available to comply with the most stringent emissions regulations.
