Verification

The objective of the United States Environmental Protection Agency (EPA) and the California Air Resources Board (CARB) Diesel Retrofit Program Verification Process is to introduce verified technologies to the retrofit market as cost effectively as possible, while providing customers with confidence that verified technologies will provide emission reductions as advertised.

This verification process evaluates the emission reduction performance of retrofit technologies including their durability, and identifies engine operating criteria and conditions that must exist for these technologies to achieve those reductions.

Please note that products that are CARB “Verified”, through a reciprocity agreement with the U.S. EPA, are recognized as verified throughout the USA.

Cummins Emission Solutions and Cummins Filtration holds the verification for the Diesel Oxidation Catalyst Closed Crankcase Ventilation System.
