Pipeline Safety Workers

Pipeline Safety

There are approximately 18,000 miles of interstate and distribution gas pipelines in Oregon that provide safe, reliable natural gas service every day.

The Pipeline would be equipped with advanced manual and automatic shut-off systems that would be continuously monitored using the latest proven technologies and communications systems

Natural Gas Pipeline Safety Overview

The Project is committed to adopting design features and operating practices that will meet or exceed industry and regulatory safety standards.

Some of the measures include:

  • Remote-controlled shut-off valves that are continuously monitored utilizing the latest proven technologies and communication systems;
  • Ongoing inspections of the pipeline both internally and externally to maintain the integrity of the  pipeline system;
  • Non-destructive examination of all welds during construction to assure the integrity of the system;
  • Use of high strength steels for the construction of the pipeline and compressor station for added safety;
  • Avoiding areas of potential landslides and using best practices to mitigate any potential risks from landslides;
  • Burying the pipeline in compliance with federal regulation; and
  • Assuring close coordination with professional and volunteer firefighters across the length of the pipeline. The pipeline’s permanent right of way will act as a natural fire break.

Pipelines are regulated by the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration, which imposes a broad range of construction and operations standards. These standards must be met before a pipeline can be placed into service.

These construction and operations standards include:

  • When the pipe is fabricated, Project representatives will carefully inspect the pipe at the mill to ensure that quality meets or exceeds both federal and industry-wide standards before it gets shipped to site.
  • The application of protective coatings and other techniques used to help prevent corrosion of the pipeline and facilities.
  • During construction, pipeline representatives will carefully inspect the construction of the pipeline and stations to assure they are constructed to the highest quality.
  • Project representatives will fully inspect the welds linking the joints of the pipeline to assure their integrity.
  • Once the pipeline is in the ground but before it is placed into service, it will be pressure-tested to verify that it can withstand pressure much higher than it will experience during its operation.
  • Shortly after construction, the Project will install a cathodic protection system, which, along with the pipe’s protective coating, is designed to prevent both internal and external corrosion.
  • In accordance with federal law, above ground pipeline markers will be used to alert the public to the presence of one or more pipelines within an easement. These markers, which contain the name of the pipeline operator and emergency contact information, will be located in highly visible locations such as next to road and rail road crossings, at fence lines and at the banks of water crossings.
  • In areas where there is a long distance between crossings, the Project will place intermittent pipeline markers so the public has access to that critical contact information throughout the pipeline’s path.
  • To help protect against third-party damage, the Project will regularly inspect the entire pipeline by foot, motorized vehicle or aerial patrol aircraft to monitor the pipeline routes and adjacent areas for encroachment on the route.
  • Pipelines undergo maintenance inspections to assure the continued integrity of the system. These inspections include annual valve and safety device inspections, as well as scheduled internal pipeline inspections.
  • The pipeline is inspected internally by utilizing a computerized inspection device known as an in-line inspection tool or “ILI” tool. These tools, also called “smart pigs,” are utilized to examine the pipe’s condition both internally and externally so that preemptive maintenance can be performed to maintain the integrity of the pipeline.
  • Oregon-based Jordan Cove Project representatives will meet with local emergency response officials, excavation contractors, landowners and local community leaders to educate them about pipeline operation and emergency response procedures.
  • Safety information regarding our operations is distributed annually to landowners, residents and businesses located near our facilities.
  • The pipeline will be continuously monitored at our Gas Control center.
  • The pipeline will become part of the Oregon 811 and nationwide One-Call system.

Vigilant monitoring, leading-edge technologies and continuous maintenance will all lead to trouble-free operation of the Pacific Connector Gas Pipeline.


Oregon 811

One of the greatest challenges to safe pipeline operations is the accidental damage caused by third parties. Local One-Call centers provide a free service to anyone planning excavation, construction or blasting activities. After a center receives a call, owners and operators of the underground utilities in the area of the planned work are notified to ensure all safety measures and standards are understood and implemented properly.

Project representatives will visit the proposed work site and mark the location of our facilities to reduce the risk of damage. To contact the One-Call center nearest you, dial 811.
