Portage Creek Cleanup. Curb cut at Crosstown Parkway. July 2012
Excavation in Axtell Creek as part of the Portage Creek Area removal action.
June 7: The first scoop of dirt is dredged from the banks of the Kalamazoo River in the time-critical removal action announced earlier in 2007.
Staff of EPA and Arcadis [contractor for the responsible parties] examine the silt curtains in the Plainwell impoundment of the Kalamazoo River Superfund site.
Craig Thomas and Sam Borries, green vests, EPA On-scene Coordinators, talk with contractors about the start of dredging at the Plainwell impoundment.
Silt curtains stretched along the first work area of the Plainwell impoundment in the Kalamazoo River.
Debris of all sizes will be removed from the Plainwell Impoundment cleanup site.
Contractors created a pebble-coated road for access to the river front. The large wooden blocks in front are joined together to create a mat. The mat is placed under heavy dredging equipment to help keep it from bogging down in the soft soil.
River traffic has been cutoff in the 1-1/2 mile stretch of the Plainwell Impoundment. The river will be patrolled to keep out trespassers for safety reasons. The patrol boats also are used for water sampling as needed.
The farthest downriver placement of silt curtain as of June 2007. The black silt curtain, which is attached to the tubular floats, will help keep contaminated sediment contained while dredging takes place.
All persons entering a potentially contaminated area of the Plainwell Impoundment cleanup must wear protective head, eye and footwear. When exiting a contaminated area, they must scrub and rinse their boots to prevent contamination of clean areas surrounding the site.
A truck dumps its load of sediment at the staging area. The soil is left for several days to drain. Water is collected and cleaned. The cleaned water can be returned to the river. Soil exceeding 50 parts per million or higher of PCB will be disposed of at a licensed landfill at Belleville, MI. Soil with less than 50 ppm of PCBs will taken to a landfill at Convis Tonwship, near Marshall, MI, not far from Battle Creek.
