BackgroundBackground Water CrossingWater CrossingBackground Background -- Water Crossing Water Crossing Survey of MT Petroleum PipelinesSurvey of MT Petroleum Pipelines

• As a result of the July 2, 2011 crude oil spill into the Yellowstone River, ensure the integrity of petroleum pipelines at major water crossings that affect rivers in Montana.

• Collaborate with State of Montana to compile an inventory of petroleum pipelines at water crossings and determine if they are currently safe.

• Determine adequacy of pipeline operators’ patrolling methods and remedial actions at water crossings for future flooding events

• Enhance PHMSA inspection guidance to ensure operators are • Enhance PHMSA inspection guidance to ensure operators are meeting all aspects of regulations, particularly with respect to protecting their pipelines from water-related damage.


PHMSA’s FocusPHMSA’s Focus

1. Petroleum pipelines (crude oil and refined products)

2. Major river crossings (greater than 100 feet)

3. Located in Montana and rivers flowing into Montana

4. Constructed with open-trench technology

5. Exposed or lack of depth-of-cover

6. River history & characteristics

7. Follow-up on mitigation measures recommended by Operators consultants
