ExxonMobil owns and operates a petroleum refinery in Baytown, Texas that is subject to the U.S. Clean Air Act (CAA) Sections 111 and 112. ExxonMobil collected emissions data from the delayed coking unit (DCU) to generate information to compare to a database from similar units and sources within the U.S. to inform future rulemaking under Sections 111 and 112. Based on U.S. EPA’s guidance for the test procedures, methods, and reporting requirements for creating such databases, a test program was designed that provided a plan to conduct emissions sampling at the DCU. This report presents the results of the test program conducted July 14 through 17, 2011.You may need a PDF reader to view some of the files on this page. See EPA’s About PDF page to learn more.
