Damage prevention is considered in Subpart L (Operations) of 49 CFR 192.
A hydrogen damage prevention program is needed for hydrogen transmission and distribution systems to prevent damage to pipelines from excavation activities such as excavation, blasting, boring, tunneling, backfilling, removal of aboveground structures and other earth moving operations.
This topic will be covered in ASME B31.12. ASME B31.8 and ASME B31.8S will be used as models or by reference.
Standards for a hydrogen pipeline damage prevention program need to be established and incorporated by reference into the federal code. Hydrogen pipeline systems need to be incorporated into existing one-call systems.
