Michigan DEQ is proposing an amendment to the Cleanup Criteria Rules for 1,4-dioxane. Due to the impending expiration of the Emergency Rule and the anticipated timeline for the comprehensive Part 201 Cleanup Criteria Rule amendment package, the DEQ is moving forward with the 1,4-dioxane rule to preserve the agency’s ability to use the best available scientific information regarding 1,4-dioxane for the residential drinking water pathway at sites throughout the state. The public comment was August 1st – August 22nd with a public hearing for the proposed rule held on August 22, 2017.
