For a transmission main, how close must the main be to the dig extent to require a Watch and Protect?

For a transmission main, a Watch and Protect is required when the excavation extends within 100 feet of the main. This practice is implemented to ensure safety and to mitigate the risk of damage to the gas lines during excavation activities. When digging near transmission mains, the close proximity increases the likelihood of causing a disturbance or rupture, hence necessitating increased monitoring and protective measures.

The specified distance of 100 feet is established in industry guidelines to maintain a safe working environment while making sure that any potential hazards can be identified and addressed promptly. Consequently, having a Watch and Protect in place enhances operational safety and compliance with regulations during construction or excavation work near such critical infrastructure.
