CONNECTING WITH INDIGENOUS PEOPLES Phillips 66 has been working with Indigenous peoples to build meaningful relationships and honor them and their connection to the land in the regions where we do business. As Todd Denton, our Senior Vice President for Health, Safety and Environment, and Projects, said at a company forum during Native American History Month, "Getting diverse Indigenous perspectives is invaluable to us as a company and industry. We want Native American people to know Phillips 66 is engaged with the tribes and Indigenous peoples." We work with tribal representatives when repairs or updates need to be made to pipelines or other assets on or near land that is important to them. For example, in the summer of 2021, Midstream leadership met with members of the Osage Nation to discuss replacing parts of the Cherokee East Pipeline between Ponca City and Glenpool, Oklahoma, which crosses native lands. Planting the Seeds of Cultural Appreciation Outside the Phillips 66 Research Center in Bartlesville, Oklahoma, you'll find three plants intertwined in an example of Native American agricultural tradition — the Three Sisters garden. In spring 2021, members of our Native American Network Employee Resource Group planted this small garden of corn, beans and squash. This method of companion planting is called a Three Sisters garden because the three plants support one another as they grow, deterring pests and increasing total crop output. Group members say these crops are the center of Native American agriculture and cuisine and provide a starting point for talking about inclusion, diversity and cultural awareness.
