Laredo Independent School District’s Clean School Bus Initiative

April 2005

The Texas State Energy Conservation, in partnership with the Laredo Independent School District, was awarded $555,000 to implement the EPA's Clean School Bus Program by retrofitting 73 school bus engines for cleaner diesel engines. The district will also purchase 5 large passenger clean diesel buses by the 2006 school year.

The Laredo Independent School District's Clean School Bus initiative seeks to reduce children's exposure to harmful emissions from diesel buses. The project will implement several clean fuel technologies that meet the 2004 federal emissions standards. The district will implement a program that will cover the 2-year period of the grant to retrofit and upgrade the bus fleet to the cleaner burning Texas Low Emission Diesel diesel fuel. This will help the Laredo area remain in attainment of air pollution standards.

During the first year, a vendor will reflash (install particulate matter traps) to the electronic control modules and install the retrofits in 50 buses; the remaining 23 buses will be retrofitted during the second year. The Laredo Independent School District Transportation Department will track mileage and fuel consumption and keep maintenance and logs for each retrofitted bus.
