The scope of this technical report is to provide a consistently applied decision making process for monitoring and observing of excavation and other activities on or near pipeline rights-of-way for 'hazardous liquid' and 'natural and other gas' transmission pipelines. The goal is to protect the public, excavation employees, and the environment by preventing damage to pipeline assets from excavation activities. NOTE Pipeline operators are encouraged to refer to the latest edition of Common Ground Alliances 'CGA Best Practices' for additional guidance.
