Owners of Regulated School Buses Required to Install CCVS before July 6, 2010
Owners of regulated school buses are required to have closed crankcase ventilation systems (CCVS) installed on regulated school buses by July 6, 2010. As of September 2009, approximately 2,300 CCVS have been installed on regulated school buses in New Jersey, ensuring a safer and cleaner ride for students.

Please note, before any installation can occur, the owner must submit a cost estimate spreadsheet to the Department for approval. If you have not done so, please complete and send your electronic Inventory/Cost estimates to the Department as soon as possible by using the Department's online portal.

NJ School Bus Emissions Study
The NJDEP has completed the NJ School Bus Emissions Study to determine if tailpipe retrofit devices further reduce levels of diesel fine particles in school bus cabins. The study concluded that tailpipe retrofit devices do not significantly reduce in-cabin particulate levels. Therefore, the Department will not require tailpipe retrofit devices on regulated school buses.

NJDEP also concluded that equipping school buses with closed crankcase ventilation systems, and ensuring that all school buses meet New Jersey Motor Vehicle Commission’s school bus inspection requirements, will substantially reduce the levels of fine particles inside school buses.

School Bus Volunteer Retrofit Program
The DEP accepted 9 school bus owners to participate in the School Bus Volunteer Retrofit Program. The participants accepted into the program operate within or near an urban complex. No additional fleets will be accepted into this program at this time. Those participants accepted into the program have voluntarily retrofitted almost 200 school buses with Best Available Retrofit Technology (BART) in addition to the required closed crankcase ventilation system (CCVS). The BART are particulate filters that are the most effective at reducing fine particle emissions from diesel exhaust.
