Grace Expansion & Modification Project in Curtis Bay

Grace has submitted an application to the Maryland Department of the Environment (MDE) for a permit to construct new equipment and make modifications at our manufacturing facility in Curtis Bay, Baltimore, Maryland. This permit application concerns projects at two of the site’s production lines: the Industrial Catalyst Operation (ICO) for manufacturing silica support products and the MAGNAPORE® Catalyst Plant (MAG/MGX) for manufacturing a polymerization catalyst. Specifically, Grace plans an expansion of the ICO line and modifications to the MAG/MGX line.

During a July 2025 Informational Meeting, we noted several questions from the community that required more research to answer. Click here to download responses to those questions.
