Alexander McKenzie-Johnson is Lead Author for a Guidance Document for Management of Landslide Hazards for Pipelines

Alexander McKenzie-Johnson, P.G., L.G., L.E.G (Texas) is the lead author for a guidance document entitled "Guidelines for Management of Landslide Hazards for Pipelines" published for the Interstate Natural Gas Association of America (INGAA) and a group of sponsors on August 21, 2020.

Alexander was also the project manager. His coauthors were Bailey Theriault, Yong-Yi Wang, Dunji Yu, Don West, Ali Ebrahimi, Martin Derby, Anthony Rice, and Alexander Greene.

Alexander McKenzie-Johnson is a Principal Engineering Geologist based in Texas with more than 17 years of professional experience focused on geohazard assessment and management for oil and gas clients.

The INGAA is a trade organization that advocates regulatory and legislative positions of importance to the natural gas pipeline industry in North America. INGAA is comprised of 25 members, representing the vast majority of the interstate natural gas transmission pipeline companies in the U.S. and Canada. INGAA members operate almost 200,000 miles of pipeline.

The interstate natural gas pipeline industry has two principal federal regulators: the Federal Energy Regulatory Commission (FERC) that is responsible for the economic regulation of pipelines, and the U.S. Department of Transportation (DOT) Pipeline and Hazardous Material Safety Administration that oversees the industry's safety efforts.


This guidance document is the result of a Joint Industry Project with sixteen pipeline operators. It provides a summary of recommended and suggested processes and steps that pipeline operators can use to provide a consistent framework for proactively managing landslide hazards that can or may affect their pipeline systems. The management guidelines help operators to identify, characterize, mitigate, and monitor actual and potential landslide hazards as well as provide guidance to perform fitness for service (FFS) assessments of pipelines affected or potentially affected by landslide movement.
