The Office of Pipeline Safety recently issued the following advisory bulletin for gas distribution pipeline facilities in the path of Hurricane Katrina. The full advisory bulletin, with introductory information, is available on OPS’s website.
To: Owners and operators of natural gas distribution pipeline facilities.
Subject: Potential for damage to natural gas distribution pipeline facilities caused by the passage of Hurricane Katrina.
Advisory: All operators of natural gas distribution pipeline facilities in the states of Louisiana, Mississippi, Alabama, and Florida are warned that pipeline safety problems may have been caused by the passage of Hurricane Katrina on August 29, 2005. Likely problems include but are not limited to damage of above ground equipment due to flooding and flying debris, damage to buried pipelines from soil movement, and water leaking into low pressure pipelines.
Pipeline operators are urged to take the following actions to ensure personal and environmental safety and the integrity of natural gas distribution pipeline facilities located in areas impacted by Hurricane Katrina:
- Conduct additional leak surveys and inspection of above ground equipment as necessary to detect any damage which may have occurred.
- For distribution systems or portions of systems that have been shut down, check for damage to piping, valves, emergency shutdown systems, risers and meter sets prior to restoring system operation and relighting customers.
- Check for water that may have leaked into low pressure systems.
- Identify and correct any conditions on the pipeline as required by the Federal pipeline safety regulations.
