  • Maintain counterparty relationships with pipeline operators, marketers, and utility account representatives (SoCal Gas, PG&E) relevant to MPC’s West Coast physical supply portfolio; ensure sufficient supply optionality to protect against demand variability and market disruptions. 

  • Ensure all transactions comply with internal risk policies, LOA frameworks, and governance requirements; document and report physical positions accurately through established risk management processes.
