Indiana Department of Environmental Management Issues Draft Operating Permit for WSP

Logansport, IN – The Indiana Department of Environmental Management (“IDEM”) today issued for public comment the draft New Source Construction and Part 70 Operating Permit, the air permit that will allow for Waelz Sustainable Products (“WSP”) to complete construction of and operate its zinc recycling facility in Cass County.

“The issuance of our draft air permit is a significant milestone,” stated Michael Englert, General Manager of WSP. “Our air permit application reflects our commitment to meet or exceed Indiana and Federal environmental standards. This is a critical step in our path to begin operations and we look forward to continuing to work with IDEM as it completes its review and approval process.”

The issuance of the operating permit will allow WSP to complete construction of and operate the facility. While ongoing construction of the buildings and their foundations has been allowed under the Clean Air Act, this pending permit will allow the production and process equipment to be installed.

WSP is a joint venture between Indianapolis-based Heritage Environmental Services and Zinc Nacional of Monterrey, Mexico. When completed, the facility will employ 90 full-time staff to produce zinc oxide, a widely-used component in numerous applications, such as sun block, diaper rash cream, cosmetics, sticky notes, dietary supplements, plastics, ceramics, galvanized steel, tires, motor oil and agricultural products like animal feed, and more, and will service the metals sector by providing a sustainable solution for the growing steel industry. The project is expected to generate substantial business tax revenue directed to both Cass County and the State of Indiana, and is slated to be operational in the second quarter of 2021.
