Cleaner Air for Kids

By  | 

School districts around the state are taking steps to make older model school buses safer for your children to ride on.

Pollution control devices, which replace the existing muffler, are being fitted on close to 400 school buses in some 200 districts. Just last year, Okemos Public Schools fitted 70 buses with the pollution control device. This year marks the second year they have applied for and received the federal grant which pays for the kits.

The device is a diesel oxidation catalyst, and it's supposed to decrease carbon monoxide and other pollutants by as much as half. The device uses a chemical process to break down pollutants in the exhaust into less harmful components.
