Niagara Mohawk and NRG Energy Inc. Sued by New York

LCG, Jan. 11, 2002--New York Attorney General announced a lawsuit against the owners of two coal-fired power plants in the western part of the state, for making improvements while failing to install pollution controls.

Eliot Spitzer, the attorney general, said that during the period from 1982 to 1999, over 50 incidences of violations of the Clean Air Act occurred. In 1999, Niagara Mohawk sold both the Dunkirk and C.R. Huntley power plants to the Minneapolis firm NRG. Prior to the sale, Niagara Mohawk made significant upgrades to the plants.

According to state regulators, federal law would have required that under "new source review" rules that are part of federal law, emissions were required to be under more stringent control.

Niagara Mohawk's contention, expressed by Ken Tompkins, is that the modifications did not represent a significant reconfiguration of the plants, and as such would not have fallen under the rule. The company filed suit against the plants' buyer in July, and looked to the state Supreme Court to enforce what Niagara Mohawk says is a provision in the sales contract that puts responsibility for new emission controls in the care of NRG.

NRG's Craig Mataczynski said that "NiMo has refused to cooperate and the state has chosen to pursue a lengthy litigation, rather than reaching a settlement that would have immediate environmental benefits."
