Community Advisory Panel

Year established: 1992

The Sweeny Refinery Community Advisory Panel (CAP) serves as a forum in which the needs of the community and the refinery’s role in the community are shared in a balanced and positive manner. CAP meetings provide an opportunity to discuss plant operations, community concerns or issues, and the current business climate. CAP members are a diverse group, including civic/academic leaders, government officials, business leaders and owners, retirees, and company management. Phillips 66 representatives on the CAP include the refinery manager, environmental, safety and security, emergency response and community relations personnel. Dedicated to generating open and honest communication between the community and the refinery, the CAP plays a vital role.

The Sweeny Refinery Community Advisory Panel is comprised of approximately 20 citizen members and 25 company members, with an average meeting attendance of 30.

Meetings are conducted quarterly, with facilities and lunch provided by the company.
