State-of-the art environmental technology will enable ExxonMobil’s planned chemical expansion at Baytown to operate within existing Texas permitted emission limits, Steve Pryor, president of ExxonMobil Chemical Company, said in a speech today at the IHS World Petrochemical Conference. “Reducing environmental impact has been an ongoing strategy at Baytown,” Pryor said. Over the past decade, the site has invested over $1.3 billion in environmental upgrades to improve air quality and achieve double-digit improvements in energy efficiency. The plans include a new multi-billion dollar world-scale steam cracker and expansion of premium polyethylene production at ExxonMobil’s Baytown site, already the country’s largest integrated refining-chemical complex, Pryor noted. The facilities will produce premium polymers incorporating company advances that have reduced film thickness by two percent per year for the last 20 years, said Pryor. He pointed out that the unique advantages of premium products, unmatched scale and integration with the company’s refining and natural gas businesses should sustain economic returns over the ups and downs of the business cycle. The Greater Houston area would benefit from $870 million per year in increased economic activity, including an estimated 10,000 jobs at the peak of construction and 3,800 permanent jobs. The Baytown project illustrates the company’s strategy for sustainability, benefiting customers, shareholders, the environment, and society, Pryor concluded. ### Statements relating to future plans, projections, events or conditions are forward-looking statements.
