Excavation Monitoring and Observation

API RP 1166

Excavation damage is a major cause of pipeline incidents and personal injuries. The American Petroleum Institute has recently released the first edition of Publication 1166, Excavation Monitoring and Observation, designed to protect the public, excavation employees, and the environment by preventing damage to pipelines from excavation activities, and to provide a consistently applied decision-making process for monitoring and observing excavation and other activities on or near pipeline rights-of-way.

To order Publication 1166, go to and search for the keyword “excavation.” The cost for non-API members is $85. For information, contact Andrea Johnson at (202) 682-8107 or
