Pipeline Safety Program

The PSC pipeline safety engineers inspect Wisconsin’s 11 natural gas utilities for compliance with state and federal pipeline safety codes. To ensure compliance with these codes, the pipeline safety engineers:

  • Visit the main office of each utility, and review all procedures required by the safety code, such as:

    • Operating and Maintenance Plan
    • Emergency Plan
    • Construction Procedures
    • Operator Qualification Program
    • Integrity Management Plans
    • Public Awareness Plan
    • Damage Prevention Plan
    • Alcohol and Drug Testing Plan

  • Review each utility's construction plan and carry out scheduled and no-notice on-site inspections of the construction.

  • Review each utility's violations from the prior year to determine if they have been satisfactorily corrected. Also, review the operating history of the utility including but not limited to leakage history, incidents and compliance.

  • Inspect gate stations and district regulators to ensure they are adequate in terms of overpressure protection and capacity.

  • Complete field checks of cathodic protection, emergency valves, bridge piping, and line markers.

  • Inspect Master Meter operators on a 3 year cycle, or as needed.

  • Inspect all jurisdictional liquid natural gas (LNG) facilities
