(Celanese) is hereby requesting a Prevention of Significant Deterioration (PSD) permit for greenhouse gases (GHG ) that will be emitted from a new methanol manufacturing unit to be located at its Clear Lake Plant in Pasadena, Texas. 1.2 Background Celanese owns and operates multiple chemical manufacturing units at the Clear Lake Plant located at 9502 Bayport Blvd., Pasadena, Harris County, Texas. An Area Map, Figure 1-1, of the Clear Lake Plant and surrounding area has been included in this application. Methanol is one of the feedstocks imported to the facility. To provide improved reliability of its methanol supply and reduce transportation expenses, Celanese proposes to manufacture methanol onsite with the construction of a new methanol manufacturing unit. The Celanese Clear Lake Plant is an existing major source under the federal PSD program. Therefore, physical changes and changes in the method of operation are potentially subject to PSD permitting requirements. The proposed project triggers PSD review since GHGs are expected to increase by more than 75,000 tons per year (tpy). The permit application has been prepared based upon EPA’s guidance, including the “New Source Review Workshop Manual,” the March 2011 document, “PSD and Title V Permitting Guidance for Greenhouse Gases (EPA- 457/B-11-001) and the memo dated October 15, 2012, “Timely Processing of Prevention of Significant Deterioration Permits When EPA or PSD-Delegated Air Agency Issues the Permit.” 1.3 Project Scope The proposed project will emit GHG emissions, and thus Celanese requests a PSD permit
