March 28, 2025 U.S. Environmental Protection Agency 1200 Pennsylvania Ave. NW Washington, DC 20460 RE: Presidential Exemption: [National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Synthetic Organic Chemical Manufacturing Industry (SOCMI): Shell Chemical LP, Geismar Plant, Geismar, Louisiana To Whom It May Concern, Shell Chemical LP, Geismar Plant (Shell Geismar) requests an extension (approved via exemption) for the compliance obligations of the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Synthetic Organic Chemical Manufacturing Industry (SOCMI HON) (referred to as the HON Rule)) For the reasons highlighted in this letter, we believe it is necessary and appropriate for the President to grant an extension (approved via exemption) under Clean Air Act (CAA) Section 112(i)(4) for sources regulated by the final rule either on an individual basis or collectively. If done collectively, we request that EPA include our regulated facilities under that collective action. We support the comments submitted separately by the American Chemistry Council (ACC) and the American Fuel & Petrochemical Manufacturers (AFPM) and are offering additional information in support of our request for an exemption under Clean Air Act (CAA) Section 112(i)(4) for sources regulated by the final rule either on an individual basis or collectively. If done collectively, we request that EPA include our regulated facilities under that collective action. Per EPA's guidance, the following information is provided: I.
