ENVIRONMENTAL, SOCIAL AND GOVERNANCE REPORT • 31 SAFETY COMMUNITY PEOPLE GOVERNANCE ENVIRONMENT Consideration of Biodiversity Impacts Valero’s growth capital projects can require thorough evaluation of potential biodiversity impacts as part of their planning, approval and implementation phases. When necessary in the pre-construction or planning phase of projects, Valero’s environmental team works closely with the engineering and commercial departments to perform environmental due diligence. The following natural and cultural resource considerations are part of the evaluation process: • Locations of surface waters and wetlands. • Threatened and endangered species habitats. • Previously recorded archaeological sites, historic structures and areas of tribal interest or significance. • Existing developed areas versus undeveloped greenfield sites. • Public lands, including parks, nature preserves and wildlife conservation areas. • Federal Emergency Management Agency floodplains. • Surface water intakes. We perform environmental field studies to verify and delineate natural resources within proposed project areas. For significant greenfield projects where alternative locations are considered, the most viable locations are surveyed. This data further drives project decisions on avoidance of sensitive features and habitats and informs site selection. In the construction phase , for site preparation and other related soil-disturbing activities, we initiate stormwater management controls to reduce impacts to lakes, rivers, streams and other surface waters. These controls consist of a variety of best management practices integrated into our Stormwater Pollution Prevention Plans, which comply with federal, state and local stormwater pollution control requirements, including planning, temporary and permanent sedimentation and erosion control measures, stream- and wetland-crossing procedures, inspections and general good housekeeping practices. During major construction and where warranted , we also provide applicable training on threatened and endangered species awareness and identification, stop-work protocols and reporting. To protect ecosystems from unintended releases of materials, we implement comprehensive pollution prevention and incident response programs. 1 2 3
