7th Circuit Court of Appeals
United States of America and State of New York, et al. v. Cinergy Corp., et al.
No. 1:99-CV-1693
U.S. District Court, Southern District of Indiana, Indianapolis Division, Judge Larry J. McKinney.
Civil. Reverses District Court ruling in the government’s favor regarding modifications involving sulphur dioxide emissions because Cinergy met the standard that was authorized by a state plan the Environmental Protection Agency approved. Finds the District Court should not have admitted evidence by the EPA’s expert witnesses. Rules that without expert testimony to support an estimate of actual emissions caused by the modifications, the government cannot prevail with respect to the charge of nitrogen oxide pollution. Dismisses cross-appeal.
