Columbia Gas Transmission, LLC v. Ohio Valley Coal Co., 2019 BL 99544 (Ohio Ct. App. Mar. 21, 2019)
Columbia Gas Transmission, LLC (“Columbia”) operated a high-pressure gas pipeline. A portion of pipeline crossed land for which Ohio Valley Coal Company (“OVC”) and Consolidated Land Company (“Consolidated”) held interest rights in the underlying coal. Columbia undertook measures to protect its pipeline from subsidence damage that OVC’s subterranean coal mining was certain to cause. An Ohio appellate court held that OVC and Consolidated were liable to Columbia for those preventative measures.
