Distribution Integrity Management Program
The focus of MidAmerican Energy's Distribution Integrity Management Program is to minimize physical risk to its natural gas distribution pipeline facilities and to protect the public, employees and the environment from natural gas distribution pipeline incidents.
MidAmerican Energy’s program elements include:
- Knowledge – Demonstrate an understanding of its gas distribution system developed from reasonably available information.
- Identify Threats - Consider the following categories of threats to each gas distribution pipeline: Corrosion, natural forces, excavation damage, other outside force damage, material, weld or joint failure, equipment failure, incorrect operation, and other concerns that could threaten the integrity of its pipeline.
- Evaluate and Rank Risk – Evaluate the risks associated with its distribution pipeline, determine the relative importance of each threat, and estimate and rank the risks posed to its pipeline.
- Identify and Implement Measures to Address Risk - Determine and implement measures designed to reduce the risks from failure of its gas distribution pipeline, including effective leak management.
- Measure Performance, Monitor Results and Evaluate Effectiveness - Develop and monitor performance measures from an established baseline to evaluate the effectiveness of its integrity management program.
- Periodic Evaluation and Improvement - Reevaluate threats and risks and consider the relevance of threats in one location to other areas.
- Report Results - Report, on an annual basis, measures to the Department of Transportation and to applicable state pipeline safety authorities as required under 49 CFR § 192.1007 and state regulations.
