From the San Francisco Chronicle:

The state’s largest school bus operator has agreed to renovate more than 2,000 buses in California to run cleaner, settling a lawsuit that accused it of exposing children to diesel exhaust in leaky passenger cabins.

The settlement was announced Wednesday by Laidlaw Transit and three environmental groups that sued the company in 2006. Without admitting any wrongdoing, Laidlaw agreed to spend $4.7 million over five years to retrofit buses that are more than five years old, and $23.6 million more to continue renovating those buses or buy new ones.

The company will also pay $6.6 million to the environmental groups and their lawyers. A San Francisco Superior Court judge is scheduled to consider the settlement next month.
