HISTORICAL INDUSTRIAL DUMPING
Carlson was retained to respond to a violation notice issued by the Illinois Environmental Protection Agency (IEPA) relating to open dumping on a 22-acre wooded parcel owned by our Client. This parcel had previously been donated to the DeKalb Park District and was formerly used as a railroad turnaround/maintenance area. The IEPA violation notice addressed asbestos containing building material in a portion of the parcel that was adjacent to a residential neighborhood.
Carlson worked together with the Client’s legal counsel and the IEPA to develop a pragmatic work plan to investigate the area in question. Samples collected across the 22-acre site were tested for both metals and asbestos. After the investigation revealed an area of heavy metals and asbestos containing soils very close to the adjacent homes, Carlson was tasked with developing a remedial approach to address the contamination. Although traditional remediation methods such as excavation and off-site disposal were evaluated, ultimately, alternative remedial strategies had to be developed because potential residential exposure was of the utmost concern.
Carlson designed and obtained Agency approval for a remedial plan that involved the installation of a synthetic and earthen cap, perimeter air monitoring, signage, fencing, vegetation restoration, and long-term inspections. Implementation of the remedial strategy included keeping the nearby residents informed about the status of the project through project status letters and a public meeting/open-house.
