What is the maximum distance from the centerline of existing pipeline facilities where soil disturbance is not permitted without an owner's representative?

• A. 10 feet
• B. 25 feet
• C. 50 feet
• D. 100 feet

Answer: (B)

The correct choice indicates that soil disturbance is not permitted within a maximum distance of 25 feet from the centerline of existing pipeline facilities without an owner's representative present. This restriction is in place to protect the integrity of the pipeline infrastructure and ensure safety measures are followed during construction or excavation activities.

The rationale behind the 25-foot limit stems from the potential risks associated with disturbing the soil around pipelines, such as potential damage to the pipeline itself, which could lead to leaks, spills, or other safety hazards. Having an owner's representative on-site allows for proper oversight and assessment of any disturbances, ensuring that the necessary precautions and protocols are adhered to in maintaining the pipeline's safety.

Understanding these distances is crucial for pipeline construction inspectors, as they need to ensure compliance with safety regulations and protect both the workers and the environment during construction activities.
