Asset Integrity Ensuring the integrity of our assets is a crucial HSEMS component. Business units develop programs and procedures to ensure proper asset design, fabrication, installation, operation and maintenance to minimize asset integrity risks associated with operations and equipment failure. Asset integrity programs include quality assurance and quality control, defined inspection and maintenance intervals for process equipment, and meeting company standards. These high-tech integrity programs and processes are designed to prevent unintentional product releases and protect everyone at our facilities and surrounding communities. Many of our company's process safety and environmental standards exceed industry requirements, promoting our goal of an incident-free workplace. PIPELINE INTEGRITY Liquids pipelines move crude oil and natural gas liquids to our operating assets and take the natural gas liquids, gasoline, diesel and jet fuel we produce to market. Our approach to pipeline safety is rooted in preventing product releases and staying ahead of maintenance requirements and emergency preparedness. Elements of these programs include exacting design and construction standards, comprehensive pipeline maintenance, 24/7 remote-line monitoring, leak detection, community education programs and strong relationships with emergency response teams across our asset footprint. Starting at the planning stage, we work to ensure a project complies with all applicable regulations and laws, including the Clean Water Act, Endangered Species Act, National Historic Preservation Act and others. We coordinate and engage with many agencies, such as the U.S. Army Corps of Engineers, U.S. Fish and Wildlife Service, and local and state regulators. We take environmental considerations into account during the planning for all pipeline projects and work to identify community needs and wants. We seek existing pipeline corridors where feasible and use advanced construction techniques to minimize the impact on the environment, local communities, wildlife and natural resources. When we build or repair pipelines, we use various state-of-the-art techniques to ensure asset integrity, such as horizontal directional drilling technology, which allows us to bury pipelines deep underneath riverbeds, preventing pipeline exposures. Since 2012, Phillips 66 has spent approximately $130 million to enhance resilience at river crossings. We support response efforts along a pipeline’s planned route, and we regularly donate equipment to emergency response teams. ~$130 million invested to enhance resilience at river crossings since 2012 28 PHILLIPS 66 2022 SUSTAINABILITY REPORT 28 Clemens to Gregory (C2G) Pipeline BRAZORIA, TX PHILLIPS 66 2022 SUSTAINABILITY REPORT OUR BUSINESSES: TODAY AND TOMORROW ENVIRONMENT AND SAFETY GOVERNANCE STAKEHOLDER ENGAGEMENT
