What is a VDECS?
VDECS is an acronym for Verified Diesel Emission Control Strategy and refers to an emission control device, designed primarily for reducing diesel particulate matter (PM) emissions, which has been verified by the Air Resources Board under the Verification Procedure regulation. The Verification Procedure provides a way to thoroughly evaluate the PM emission reduction capabilities of a variety of diesel emission control strategies as part of a retrofit in-use program. It ensures that emission reductions achieved by a control strategy are real, the device is durable and covered by minimum warranty requirements specified in the Verification Procedure, and that production units in the field are achieving emission reductions which are consistent with their verification. 20.
