We are committed to reducing freshwater withdrawals at our facilities. Our efforts extend to our Houston Headquarters, where we collect and reuse rainwater. Several of our refineries have developed processes to meet the facility's unique needs. Recycling water is one way we do that. Understanding the local water demand and the potential for water scarcity in the future are key considerations, as we prioritize projects to improve efficiency and decrease our environmental footprint. PONCA CITY REFINERY Our Ponca City Refinery reduces its freshwater usage by reclaiming water and harvesting stormwater. This practice has reduced freshwater needs by 2,500 GPM, or 1.3 billion gallons per year. That's a 32% reduction in our freshwater usage. BORGER REFINERY Our Borger Refinery has several ways to conserve water, including recovering 200 GPM of condensate for use in boilers. This saves 105 million gallons of freshwater each year. LAKE CHARLES REFINERY At our Lake Charles Refinery, we recycled 378 million gallons in 2021. That’s a 17% reduction in our raw water demand.
