To whom it may concern -- Please see attached, a request for Presidential Exemption for Westlake Chemicals & Vinyls LLC's HON-covered facility at 1600 VCM Plant Road, Westlake, Louisiana 70669, as requested by U.S. EPA of the regulated community. As explained in greater detail in the attached letter, Westlake is seeking a Presidential Exemption under the New Source Performance Standards for the Synthetic Organic Chemical Manufacturing Industry and National Emission Standards for Hazardous Air Pollutants for the Synthetic Organic Chemical Manufacturing Industry and Group I & II Polymers and Resins. See 89 FR 42932; May 16, 2024 (HON rule). As Westlake's evaluation of the requirements under the HON rule progresses and we continue to develop our compliance plans, Westlake may have additional detail or more concrete information related to the technical challenges, time required and costs for coming into compliance with the HON rule. Some of that more detailed information may include confidential business information which Westlake would be willing to provide under the appropriate protections for such competitive and trade secret information. Please contact Paula McCain at pmccain@westlake.com or 337-7084688 should EPA or the President require more detailed information about specific impacts to Westlake's Lake Charles North Facility. Thank you for the timely consideration of this request. Sierra Club FOIA 2025-EPA-04883 ED_018388_00005517-00001 SC_EVERSPLIT0005403
