Where must valve locations be established according to CFR 195?

• A. Each side of a water crossing that is more than 100 feet wide
• B. At every crossing
• C. Only at the beginning of the pipeline
• D. Every 500 feet along the pipeline

Answer: (A)

Establishing valve locations is crucial in pipeline management for safety and environmental protection. According to CFR 195, it specifically mandates that valves must be installed on each side of water crossings that are more than 100 feet wide. This requirement aims to provide a means to quickly shut off the flow of product in the event of a leak or spill, thereby minimizing the potential impact on waterways and protecting the environment.

This regulation is based on the understanding that wider water bodies present a greater risk for potential contamination in the event of a pipeline failure. By ensuring that valves are present at such critical locations, operators can facilitate a faster response to mitigate environmental damage and uphold safety standards.

Other options, while considering valve placement in pipeline construction, do not align with the specific guidelines outlined in CFR 195 concerning water crossings, making them less applicable. Valves at every crossing could be excessive since not all crossings may be of significant risk. Similarly, placing valves only at the beginning of the pipeline or at regular distances like every 500 feet does not address the specific threat posed by wider water bodies, thus underscoring the importance of adhering to the guideline that emphasizes valve placement specifically in relation to water crossings.
