Remaining Useful Life of Vehicles and Lifetime of CERs

Section 207 Section 207.508  Remaining Useful Life of Vehicles and Lifetime of CERs a)         If emissions from retired vehicles are modeled, the remaining useful life of retired vehicles shall be three years. b)         If emissions from retired vehicles are measured, the remaining useful life of retired vehicles shall be a minimum of two years.  Vehicle scrappage sponsors and managers may demonstrate to the Agency that a remaining useful life of more than two years should apply to CERs generated using a measure/model or a measure/measure method.  To make this demonstration, the vehicle scrappage sponsor or manager shall provide the Agency with sufficient information to substantiate that a greater remaining useful life of retired vehicles is justified. c)         CERs are valid for the same period as the remaining useful life of the retired vehicle as specified in this Section.
