General Electric Co. says it will study a possible expansion of its PCB cleanup of the upper Hudson River after a request by New York state Comptroller Thomas DiNapoli.

GE, which released poly-chlorinated biphenyls into the river decades ago, is preparing for a fourth season of dredging as part of a federal Superfund project. But DiNapoli says Monday that GE could potentially be found liable for contamination outside the Superfund site and filed a shareholder resolution calling on the company to evaluate its risks.
