How often must Class 3 line locations be inspected for locations OTHER THAN Highway and RR crossings?

The frequency of inspections for Class 3 line locations, specifically for areas other than Highway and RR crossings, is established to ensure safety and compliance with regulatory standards. The correct answer specifies that these locations must be inspected at least twice during each calendar year, which amounts to approximately every 7.5 months. This schedule strikes a balance between thorough surveillance and practical resource management, addressing the potential hazards associated with the pipeline's condition and surrounding environment.

This routine inspection frequency allows operators to promptly identify and remedy any issues, ensuring the integrity of the pipeline is maintained and minimizing risks associated with leaks or other malfunctions. It reflects an understanding of the operational environment where Class 3 lines are located, focusing on frequently monitoring areas that may be more susceptible to issues, such as land erosion or unauthorized encroachment.

In terms of inspection intervals set by regulations, this standard aligns with industry practices designed to uphold safety while also accommodating the logistical aspects of pipeline management. The inspection rate provides adequate oversight without causing excessive interruption to regular pipeline operations.
