AQM retrofitted nearly 400 older model schools buses with Diesel Oxidation Catalysts. These pollution control devices reduce harmful tailpipe emissions, protecting sensitive groups such as children and the elderly. Annually, these devices remove over 5 tons of carbon monoxide, 3 tons of unburned hydrocarbons and 2 tons of particulate matter. Partial funding for this project was provided by the Environmental Protection Agency's 2007 Clean School Bus USA grant. |
