Criticality: High Progress: Not Addressed Score: 40 DOT Relevance: ยง192.614
Description of Key Area
Damage prevention is
considered in Subpart L (Operations) of 49 CFR 192.
Discussion of Criticality
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.
Discussion of Progress
This topic will be
covered in ASME B31.12. ASME B31.8 and ASME B31.8S will be used as models or by
reference.
Recommendations
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.
