Transmission Pipeline


The Transmission Integrity Management Program is MidAmerican Energy's program for minimizing physical risk to its natural gas transmission pipeline facilities. The program helps ensure that risks associated with natural gas transmission pipeline integrity are effectively managed and that the public, MidAmerican Energy's employees and the environment are better protected from natural gas transmission pipeline incidents. The processes and procedures set forth in this program apply to natural gas transmission pipelines located within high consequence areas where a natural gas pipeline incident could have significant impact on people, business or the environment.

The program was mandated by the U.S. Department of Transportation Pipeline and Hazardous Materials Safety Administration and is part of federally mandated rules designed to improve the safety of natural gas transmission systems. It consists of five elements:
  • Integrity Management Plan – Processes and procedures followed to ensure compliance with the Gas Integrity Management Rule. The plan establishes procedures for identifying high consequence areas; gathering, reviewing and integrating data; performing risk and integrity assessments; applying appropriate preventative, mitigation and remediation measures; and assigning reassessment intervals to continually evaluate the integrity of covered segments.
  • Performance Plan – Processes and procedures used to measure the effectiveness of the program by MidAmerican Energy.
  • Communications Plan – Processes and procedures for communicating Performance Plan results.
  • Management of Change Plan – Identifies and considers the risk impact of technical, physical, procedural and organizational changes to the natural gas transmission pipeline systems.
  • Quality Management Plan – Processes and procedures established to ensure the requirements of the program are being met, documented and continually improved.
MidAmerican Energy is committed to protecting the public, its employees and the environment; improving the performance of its natural gas transmission 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.
