U.S. EPA has completed excavation and site restoration. A total of 10,479 tons of contaminated soil were excavated for off-site disposal, 4,500 gallons of oil were recovered, and 467,050 gallons of contaminated water were treated.
On-site frac tanks that were used for water treatment and free product collection, and heavy equipment used during phases of operation have been decontaminated and demobilized from site. Two trailers remain on site and will be demobilized November 17.
All waste water, waste-water treatment media, and contaminated soil have been sampled and removed for off-site disposal.
A Geoprobe investigation was completed of the excavated area to confirm that heavily contaminated soil had been removed. The survey led to additional tree removal to facilitate removal of overburden from the south rim of the excavation and further excavation of an area to the south of the original proposed area of contaminate soil where subsurface dark, black, contaminated gravel were found.
Michigan Department of Environmental Quality (MDEQ) conducted additional soil borings, which showed heavily contaminated source material had been removed. On November 6th, U.S. EPA med with MDEQ and transfered the site back to state control.
MDEQ has set aside funds for backfilling and plan to begin this year.
