Do we need to data log each school districts entire fleet prior to commencing the filter installations?
The Clean Buses for Kids Program prefers that all buses that are going to be retrofitted with diesel particulate filters (DPFs) that require a minimum exhaust temperature be data logged. However, we understand that it is time and resource intensive to data log each one. Therefore, it is acceptable to data log a representative sample of buses that includes, at a minimum, the “worst case” buses prior to beginning the filter installations. You should work with the school district to determine an appropriate sample of buses based on the buses’ regular routes and engine configurations. More information on data logging can be found in the “Tips for Installation” section of the Technology Overview (PDF 224K) and the data logging requirements of the Payment Documentation (PDF 98K).
