Site Specific Information for Ethylene Oxide (EtO) for: Sasol Chemicals (USA) – Lake Charles Complex, Westlake, La EIS Facility ID 8468011 AI 3271
As EPA pursues its mission to protect public health and the environment, addressing ethylene oxide (EtO) remains a major priority for the Agency. EPA’s National Air Toxics Assessment (NATA), released in August 2018, identified a number of areas across the nation with potentially elevated risk from continuous exposure to EtO in the outdoor air. NATA estimated these risks based on EtO emissions from 2014, which were the most recently available at the time.
NATA is a screening-level analysis that is intended to identify pollutants or areas for closer examination. EPA and the State air agencies are working together to better understand emissions in areas that NATA identified as potentially having elevated risk. State air agency partners are in discussions with individual facilities to identify opportunities for reducing EtO emissions from those facilities. EPA is reviewing its national regulations for industrial facilities that emit EtO. Actual risks today may be lower or higher than NATA estimated due to several factors, including updated or more refined facility emissions information or recent facility changes including the installation of pollution controls.
This page contains links to documents that may be downloaded that describe efforts to understand better the emissions from the specific site identified in the Title of this page. We will update this page as new reports and developed. EPA is providing this information to address, in part, the EPA Office of Inspector General’s Management Alert (dated March 31, 2020) for the site.
