Mazonia-Braidwood State Fish and Wildlife Area - ComEd 

Grundy County

On or about June 25, 2000, Commonwealth Edison Company (Com-Ed) released 4,450 gallons of diesel loil and/or other petroleum material into water in a perimeter ditch at the Braidwood facility in Grundy County. The release resulted in impacts to the soil, surface water, and groundwater, and adversely impacted, or threatened to impact, flora, fauna, and aquatic life. In addition, the oil release traveled to a nearby wetland and cause the deaths of fish, amphibians, reptiles, and migratory birds.

An NRDA was completed by the Illinois Natural Resources Trustees. A settlement was agreed to by all parties. The matter was settled in September of 2002.

Due to the permanent losses of fish, amphibians, reptiles and migratory birds, a moist soil project was proposed and implemented at the nearby Mazonia-Braidwood State Fish and Wildlife Area. This project is providing habitat for all wildlife that were permanently lost and is providing the natural means to replace lost ecological services. A final restoration plan was drafted and all funds have been utilized for the restoration project implementation. Continued monitoring of the restoration project is ongoing to evaluate the wildlife that utilized the moist soil unit. A summary of these findings will be available in the future.
