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.
Dow will contact residential property owners residing in the initial sampling area (see Eligible Properties) to request permission to sample the soil on their properties.
Dow will analyze soil samples to determine the level of dioxins. Properties that test above 250 ppt will be offered cleanup. Properties that test at or below 250 ppt will not require cleanup.
Upon receiving the soil sampling results, Dow will develop a specific remediation plan for each property, which will be reviewed with the owner. Upon consent of the property owner, Dow will conduct cleanup activities to remove the top 12 inches of soil from the property, replace it with new soil and return the lawn and any plantings to their previous state.
Cleanup activities will be conducted as safely and as quickly as possible, at Dow's expense.
Upon completion of remediation, property owners will receive a confirmation letter from the Michigan Department of Environmental Quality (MDEQ).
