Distribution Pipeline Safety

MidAmerican Energy is committed to protecting the public, its employees and the environment; improving the performance of its natural gas distribution pipeline system; reducing its risk profile; and ensuring compliance with all applicable state and federal integrity management regulations.

Executive management has approved the processes and procedures within this program and has mandated adherence to them. Employees at all levels of the organization are responsible for leading and engaging in tasks to meet the program goals and objectives.

Natural gas is transported from delivery points on interstate and intrastate transmisison pipelines to most homes and businesses through small-diameter distribution lines.

Natural gas safety tips for homes and businesses served from our distribution system, such as knowing what to do in the event of a leak or emergency, is available on our natural gas safety page.

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.
