Superfund Process

Welcome to the Superfund page! This page is designed to provide an overview of the EPA’s Superfund program and what it does, the role of the MPCA in local Superfund processes, as well as map local Superfund sites in order to provide a more accessible view of the environmental issues in the area.


What is it?

Superfund is a US Government program run by the Environmental Protection Agency, funded by the US Government and supplemented by the responsible parties. It was started in 1980 as a response to environmental toxic waste dump emergencies in the 1970’s. It allows the EPA to clean up toxic sites, in addition to alerting responsible parties to take financial responsibility for the cleanup and monitoring of the affected sites.

How does it work?

The Superfund process is extremely complex, and involves a large amount of steps and processes that vary based on the severity and location of the site. For nearly all sites, the process goes as follows:

1. A site is identified, assessed, and then placed on the EPA’s National Priorities List.
2. Responsible parties are identified, notified, and brought into the process.
3. Cleanup plans are discussed, established, and implemented
4. Remediation occurs, site is constantly monitored
5. Measures are put into place to monitor site after acceptable level of cleanup is complete

Who are they?

The MPCA or Minnesota Pollution Control Agency is a Minnesota Government Agency that is tasked with environmental protection of the state. They are responsible for any environmental disasters that occur within the state of Minnesota, which includes administering the Superfund process for any sites located within the state, In addition, they act as an intermediary between communities and larger government organizations, such as the EPA.
