ENVIRONMENTAL, SOCIAL AND GOVERNANCE REPORT • 29 SAFETY COMMUNITY PEOPLE GOVERNANCE ENVIRONMENT Hazardous Waste Management Program We focus on reducing the generation of solid wastes across all of our operations. Reducing at the source, reusing, recycling, and repurposing of materials are key components of our waste reduction program, which also includes regular waste reviews, risk assessments, waste stream prioritization and training . Waste Management Innovation Since 2010, we have increased our waste disposal efficiency by using the Roberoller tankers. This eliminated the need of approximately 5,700 over-the-road truck trips, disposal of 11,400 HDPE liners, and avoided the use of more than 2.2 million gallons of water that would have been used to wash out containers. Spill Prevention Valero is focused on reducing spills from its manufacturing and processing facilities, pipelines and vessels. We protect our people and the environment through operational excellence and technology, always with the goal of zero spills. The environmental scorecard incidents metric of the all- employee bonus is weighted to the intensity of environmental incidents with greater impact for more significant events, including the severity of spills. 2021 Highlights 1.9 MILLION GALLONS OF WASTE REPURPOSED AS FUEL AT THIRD-PARTY FACILITIES, DISPLACING THE EQUIVALENT OF MORE THAN 6,500 TONS OF COAL AND PREVENTING MORE THAN 27,000 TONS OF CO 2 96% OF ALL REFINERY EXEMPTED AND HAZARDOUS WASTES WERE RECYCLED 7 55% OF ALL HAZARDOUS WASTE WAS RECYCLED, INCLUDING 26.5 MILLION POUNDS OF CATALYST 7 Refers to exempted hazardous waste as per regulatory classifications and per footnote EM-RM-150a.1 on page 109.
