Technology company Honeywell is suing Sunoco in federal court to claw back some of the nearly $500 million the former was ordered to pay in cleaning up Onondaga Lake over more than two decades.

The complaint, filed in the U.S. District Court for the Northern District of New York, adds to another lawsuit from Honeywell against ExxonMobil over similar claims that the company was also responsible for polluting the lake and should therefore have to share the cost of cleanup.
