GEDDES (AP) -- A project to clean up a heavily polluted lake in Central New York is set to begin.

Honeywell International officials tell the Syracuse Post-Standard they're continuing to prepare the shoreline of Onondaga Lake in Geddes as part of the cleanup. 

Part of the lake bottom will be dredged and part of it capped to keep mercury and other chemicals from contaminating fish.

Dredging should begin this spring or summer and work is expected to last until 2016.

Honeywell succeeded Allied Chemical, which released mercury and other chemicals into the lake. Honeywell has agreed to spend $550 million and Onondaga County is spending $600 million.

From 1946 until 1970, Allied dumped about 165,000 pounds of mercury into the lake. It is on the federal Superfund list of toxic waste sites.
