On February 16, 2012, the Michigan Department of Environmental Quality (MDEQ) announced an agreement with Dow on a proposed plan to resolve the long-standing dioxin issue in the city of Midland.
As part of the proposed resolution, Dow will sample residential properties near the manufacturing site for the presence of dioxins above a site-specific action level. MDEQ is proposing a level of 250 parts per trillion (ppt) for residential soils in the Midland area. This level was developed by MDEQ, in accordance with U.S. Environmental Protection Agency-approved risk assessment procedures, and with input from EPA. Sampling data and bioavailability soil studies conducted in the Midland area were factored into the calculations.
The exact area for remediation will be determined by soil sampling results. The initial area for sampling has been generally defined as the area closest to Dow Michigan Operations site, north to Eastlawn Drive, west to Rodd Street and east to Waldo Avenue. A smaller area to the southeast of the intersection of Washington and Ashman Streets also will be sampled. The footprint of these areas will be refined as the program is implemented and more sampling information becomes available.
