SUMMARY: This document provides guidance to operators of gas transmission pipelines on the requirement in 49 U.S.C. 60109 that operators begin the baseline integrity assessment of pipeline segments located in high consequence areas no later than June 17, 2004. Trade associations representing natural gas pipeline companies affected by this requirement, have asked for guidance on what actions an operator must take to begin a baseline assessment. This document provides guidance to gas transmission operators on what initial steps RSPA/ OPS expects each operator to take to begin the baseline integrity assessment to meet the intent of the statute.
