Fostering the Remediation & Redevelopment of
Manufactured Gas Plant Sites

James R. Dunn


Presentation Title

Successful Completion of Remedial Construction of the Ashland/Northern States Power Company Lakefront Superfund Site With an Eye Towards Redevelopment (with insights on 30 years in the industry)

James R. Dunn, Retired, (Former Hydrogeologist – Remediation & Redevelopment, Wisconsin Department of Natural Resources)


After almost 30 years of investigation, litigation, and remediation, the majority of the on land (phase I) and sediment (phase II) remediations have been successfully completed.  As with many of the complex MGP sites, this project took a team of responsible parties, contractors, and regulators to make it happen, working adaptively throughout the process.  In the end, the standards were met.  This presentation will focus on the Phase II sediment remedial effort and future redevelopment. It will also include insights from a retired Wisconsin Department of Natural Resources hydrogeologist into how.


Mr. Dunn joined the Wisconsin Department of Natural Resources (DNR) in 1989 as a hydrogeologist.  He has over 25 years of experience in the investigation, remediation and redevelopment of manufactured gas plants.  Over the past 25 years he has managed the assessment, investigation, remediation and redevelopment on hundreds of contaminated properties in Wisconsin.  He is currently responsible for and acts as project manager for the State of Wisconsin for the Ashland/Northern Stated Power Company Superfund site in Ashland, Wisconsin.  As Project Manager for the State of Wisconsin, Wisconsin Department of Natural Resources, he coordinates all technical responses to the Environmental Protection Agency (EPA), for the Ashland site.  This includes all State of Wisconsin technical issues.  The State team includes staff from the Waters, Air, Waste, Office of the Great Lakes and Enforcement programs at the DNR as well as the Wisconsin Health Department.  MGP historical background is an area that Mr. Dunn has spent much time on and believes that an understanding of the historical operations of the specific MGP is instrumental in the efficient and effective investigation, remediation and redevelopment of that MGP.
