**NEW JERSEY DEPARTMENT OF TRANSPORTATION SCHOOL BUS RETROFIT, STATEWIDE** 

**RACM Analysis Control Measure:**  School Bus Retrofit **Description:** Older, higher - emitting buses will be fitted with emissions reducing retrofit technology. **Documentation:**  Environmental Protection Agency, Clean School Bus USA: http://www.epa.gov/cleanschoolbus/index.htm  School Bus Transportation News, K - 12 Enrollment / Transportation Data, 2002 - 03 School Year: http://www.stnonl ine.com/stn/data_statistics/2002 - 03_schoolyear.htm **Methodology :**  All model year 1992 - 2002 buses in the fleet will be equipped with retrofit technology. Retrofitting model year 1992 - 2002 buses is assumed to have the greatest potential to reduce emissions d

ue to existing regulations and fleet age. **Inputs/A ssumptions:**   A Lubrizol Engine Control Systems, Purifilter Diesel Particulate Filter would be used to retrofit the buses. o This filter is a verified EPA retrofit technology and is estimated to reduce VOC emissions by 85% and PM emissions by 90%. o The filter has no affect on NOx emissions.  All model year 1992 - 2002 buses in the fleet will be equipped with retrofit technology.  Retrofitting model year 1992 - 2002 buses is assumed to have the greatest potential to reduce emissions due to existing regulations and fleet age.  58.1% of all school bus VMT can be attributed to model year 1992 - 2002 buses.  Because no estimates could be found on the affect of retrofit technology on SO 2 emissions, a zero benefit was assumed.  MOBILE6.2 was used to generate emission factors and VMT.  The expected useful life of retrofit equipment is 6 years.  School buses operate 180 days per year.  Itcosts an average of $7,500 to retrofit one school bus.  There are 21,228 buses operating in the state of NJ.  58.1% of the operating school buses are assumed to be MY 1992 - 2002. **Results:** Total Affected VMT: Daily Model Years 1992 - 2002 = **76,659** miles/day Annual Model Years 1992 - 2002 = **28,881,989** miles/year**NEW JERSEY DEPARTMENT OF TRANSPORTATION SCHOOL BUS RETROFIT, STATEWIDE**
