Excavation Technologies, Inc. v. Columbia Gas Co. of PA
2009 Pa. LEXIS 2794 (Pa., December 29, 2009)

The Pennsylvania Supreme Court held that a utility company’s failure to properly mark the location of its lines under the Pennsylvania One-Call Act did not render it liable to an excavation contractor who struck the lines and suffered purely economic losses. It rejected the argument that the utility should be liable under § 552(3) of the Restatement (Second) of Torts because of its public duty to mark the lines.
