OSHA’S VOLUNTARY PROTECTION PROGRAM Across our Refining, Midstream and Lubricants assets, 31 facilities have Occupational Safety and Health Administration (OSHA) Voluntary Protection Program (VPP) STAR recognition, meaning about half our U.S. employees work at a VPP site. Six contractor companies at our sites also participate in VPP. The STAR recognition is OSHA's highest workplace honor, and to maintain this status, each site must complete self- evaluations every year and undergo an OSHA site inspection every three to five years. In 2021, our Tacoma Terminal in Washington, and our Coke Handling Terminal and Clifton Ridge Marine Terminal in Louisiana all achieved VPP STAR recertification for another five years. ISO CERTIFICATIONS Our facilities follow Phillips 66 quality management systems, and many are certified to International Organization for Standardization (ISO) measures. Some customers require this certification of our polypropylene products and lubricants, and even though we don't certify all units to ISO, our comprehensive process safety event (PSE) and environmental management systems meet or exceed ISO standards. Our Lubricants business conforms to the ISO 14001:2004 Environmental Management System. Five of our lubricants facilities have certification to ISO 14001 and the ISO 9001:2015/IATF16949:2016 Quality Management System Standard. Lubricants Research and Development is accredited to the ISO/IEC 17025 standard for testing and calibration laboratories. Bayway Refinery's polypropylene business in Linden, New Jersey, is certified to ISO 9001:2015 for the design and manufacturing of pellets. We have numerous practices for containing and mitigating loss. Pellets are piped to an on-site storage silo, creating a closed system. From there, the product is blended and fed into rail cars for transportation to customers. We inspect rail cars for operable and closed caps and valves. Environmental performance includes collecting scrap and vacuuming sumps to recycle pellets, preventing plastic pellets from leaving the property. We are prepared with booms and vacuum trucks should a spill occur. Our Bayway facility management and employees are committed to Operation Clean Sweep and support the goal of zero pellet loss. We have also implemented a rail car return policy intended to eliminate the possibility of pellets entering the environment due to unsealed or improperly sealed rail cars returning from our customers. Wood River Refinery’s odorless mineral spirits and benzene business lines in Roxana, Illinois, conform to ISO 9001:2015 Quality Management System Standards. In the United Kingdom, the Humber Refinery is working to transition to the new ISO 14001 standard and is certified to the 2015 version. 20 PHILLIPS 66 2022 SUSTAINABILITY REPORT Polypropylene unit at Bayway Refinery LINDEN, NJ OUR BUSINESSES: TODAY AND TOMORROW ENVIRONMENT AND SAFETY GOVERNANCE STAKEHOLDER ENGAGEMENT
