ENVIRONMENTAL, SOCIAL AND GOVERNANCE REPORT • 39 SAFETY COMMUNITY PEOPLE GOVERNANCE ENVIRONMENT At Valero, we take innovative approaches and leverage advanced technology to minimize use and eliminate waste. In 2021, we recycled more than 17 times the amount of fresh water we withdrew to support our refinery operations, primarily through the recirculation of water in high- efficiency cooling towers. • Our Three Rivers refinery sends treated wastewater for irrigation use for hay production. • Our Corpus Christi refineries pay into a broad industry fund that provides water- supply security and supports research and plans for the construction of a desalination facility to serve industrial users. • Our Texas City refinery has an option agreement to purchase treated wastewater from the city and is evaluating a project to reuse this water source in the refinery. • Our Welcome ethanol plant was one of the industry’s first operators to achieve “zero discharge” of wastewater by recovering and recycling process water and stormwater. • Process water and stormwater are treated as necessary before discharging or reusing. Our wastewater treatment plants are generally comparable to those operated by most cities.
