Class 3 line locations for Highway and RR crossings must be inspected how often?

For Class 3 line locations, which are pipelines that operate under higher pressures and can pose significant risks, special attention is required at highway and railroad crossings due to the increased potential for accidents and the proximity to populated areas. The correct frequency for inspections is designed to ensure safety and compliance with regulatory standards.

The chosen answer indicates that inspections must occur every 4.5 months, with a minimum of four inspections per calendar year. This frequency allows for sufficient monitoring of the pipeline integrity and any changes or threats that may arise due to environmental factors or increased traffic, thus proactively addressing potential risks.

Inspecting these locations frequently helps ensure that any issues, such as erosion, subsidence, or other hazards that could affect pipeline integrity, are identified and addressed promptly. Regular inspections are critical in maintaining safety standards and reducing the likelihood of pipeline incidents in sensitive areas.
