Ill. Due to the significant amount ofplanning time and capital expenditure currently ongoing at Shell Geismar to assess, define, select technologies, select vendors, procure long lead item equipment, execute construction, and commission new equipment and practices to meet SOCMI HON requirements, Shell LP requests a two-year extension. Since EPA has publicly stated an intent to reconsider the provisions of SOCMI HON, should such reconsideration result in changes to the regulatory requirements, an additional extension may be required. Shell Chemical LP appreciates consideration of this request. Should any additional information be needed in support of this request, please contact me at kevin.poche@shell.com Sincerely, Kevin J.
