The Ohio Manufacturers’ Association (OMA) is engaging early as Ohio Environmental Protection Agency (EPA) begins reviewing water-quality rules that could affect permits, compliance obligations and operating flexibility for manufacturers in parts of the state. OMA submitted comments during the agency’s early stakeholder outreach on potential updates to beneficial use designations in the Maumee, Ashtabula and Muskingum drainage basins and asked to stay involved as draft rule language is developed.

Those designations help determine the water-quality standards applied to specific rivers, streams and other surface waters, shaping permit limits and Section 401 water-quality certifications. Ohio EPA said the review could revise classifications for certain waters, add currently undesignated waters to the rules and verify existing designations as part of the agency’s required five-year review.

Because more stringent classifications can directly affect permitting flexibility and costs, early engagement helps ensure the process remains transparent, workable and grounded in practical conditions. 4/7/2026
