Community Liaison Services

Mission

To advance PHMSA’s pipeline safety mission by proactively engaging with pipeline stakeholders, providing technical expertise, and leveraging technology, data, and information to reduce pipeline risks and influence change through program and policy development.

Vision

To serve as “trusted” and “credible” stewards of public safety and environmental protection by raising awareness and influencing change to continuously improve pipeline safety.

If you need assistance with any of the following pipeline safety related matters, please contact a PHMSA Community Liaison today:

  • Pipeline safety policy/programs (damage prevention, public awareness, emergency response, PIPA, etc.)
  • Pipeline stakeholder engagement and outreach
  • Pipeline technical services and support (public inquiries, whistleblowers, post incident/accident communications, siting and permit initiatives)
  • Questions about pipeline safety in your community

Community Liaisons are located within each PHMSA region. Contact information for the Community Liaison for your state is noted below.
