The Ten-Mile Drain Site is located northeast of the City of Detroit and on the western shores of Lake St. Clair in St. Clair Shores, Macomb County, Michigan. The site includes a portion of the Ten Mile drain (TMD), a concrete storm sewer system fifteen feet below ground, and the nearby Lange and Revere Street canals which connect to Lake St. Clair. Polychlorinated biphenyls (PCBs) are known to have migrated from a historical release of PCB-containing oil into the storm sewer system, either from a surface spill or illegal dumping, through the TMD system and then discharged into the canals. The area of concern for this site includes TMD sewer lines in and around the intersection of Bon Brea Street and Harper Avenue in St Clair Shores, Michigan, the Lange and Revere Street canals, and possibly other areas to be determined after further investigation and sampling.

Site Updates

See weekly updates on this summer's work

June 2015

The U.S. Environmental Protection Agency plans to dig up and replace two manhole vaults, along with the underlying stone bedding and backfill materials, where the highest levels of polychlorinated biphenyls (PCB) have been found at the Ten Mile Drain (TMD) site. This work, near the intersection of Bon Brae Street and Harper Avenue, is expected to immediately reduce the volume of contamination and prevent the seepage of PCB contamination into the TMD storm sewer system and the Lange and Revere Street canals.

EPA contractors will start construction at manhole vault 7179 and complete work at this location before moving across the street to J01. During construction at vault 7179 Bon Brae Street will be closed on the west side of Harper. During construction at vault J01 Bon Brae Street will be closed on the east side of Harper, and one north bound lane on Harper will be closed because this vault extends into Harper Avenue.

Workers will control dust during construction, properly treat soil and sludge for disposal at a specially permitted facility, and monitor air quality and noise around the work area.

Workers will temporarily divert water from the TMD system to remove the vaults. Before installing new manholes, they will place a liner on the open surface to separate existing soil from the new clean bedding and backfill material. Once the new manhole vaults are installed, any damage done to the road and sidewalk will be repaired and workers will place two monitoring and recovery wells on the sides of the new vaults for a total of four wells. The wells and wipe samples taken within the vaulted manholes will provide data to support future decisions about a site-wide cleanup.

Earlier site updates

National Priorities List (NPL) Status Update

In September 2010, the Ten-Mile Drain site was placed on the National Priorities List (NPL). The NPL is a roster of the nation's hazardous waste sites eligible for investigation and cleanup under EPA's Superfund program. The transfer of the site to EPA's remedial branch will allow for additional funding and resources.
