Site Description
EU002 is in Saginaw Township, Saginaw County, Michigan, and is contaminated with dioxins and furans from Dow Chemical Company's Midland Plant.

EU002 is located along West Michigan Avenue and is generally located approximately 7 miles to the west and 1 mile to the south of the intersection of Interstate 75 and State Route 46 in Saginaw, Saginaw County, Michigan.  EU002 is approximately 3,000-foot long by 500-foot wide area along the northeast bank of the Tittabawassee River, 3 miles upstream of the confluence of the Tittabawassee and Shiawassee Rivers.  EU002 includes a 5-acre public park named West Michigan Park (WMP); a condominium complex located directly adjacent to and west of WMP; several residential properties directly adjacent to and east of WMP.  Site activities will be concentrated to the areas of WMP; two elevated contamination areas near single condominiums and four elevated contamination areas near single-family residents (ECAs); and a moderate-use zone (MUZ) in several areas located on the wooded portion of the residential properties.  EU002 is located approximately 15 miles down river from the Midland Plant.

Planned Removal Actions
Removal of remaining gravel drive and parking lot and paving will be conducted after completion of excavation/backfilling of the park.  After the vegetation has been re-established, re-installation of park equipment will begin and the park will be re-opened to the public.

Next Steps
Continue barrier control plan implementation of ECAs 1-5.  Additionally, evaluation of property usage of the moderate use zone (MUZ) will begin.

Key Issues
Dust and turbidity monitoring will continue at the site until excavation and fill activities have been completed at the site. Only one exceedence from dust monitoring was recorded however, it was documented to be unrelated to activities associated with the site.

A Post Removal Site Control plan will be finalized for EU002 to conduct sampling and monitor the integrity of the cleanup after flood events.  Schedule and completion date are subject to weather conditions.
