Phase II Drilling Investigation, Response Action Plan, and Regulatory Assistance: SP 6221-107 - TH 61 Corridor

Brief description: The goal of this project is to identify, characterize, and properly manage contaminated materials located in the project corridor from pre letting through construction completion. Contaminated materials include, but are not limited to, soil, groundwater, and soil vapor. The information collected during the investigations will be incorporated by MnDOT into project design plans and specifications, and other pre letting activities. Specifically, the goals of the project are to:

1. Conduct Phase II Drilling Investigations of soil, groundwater and soil vapor throughout the project area.
2. Obtain liability protections for property acquisitions from the Minnesota Pollution Control Agency (MPCA) and/or Minnesota Department of Agriculture (MDA) as needed.
3. Engage stakeholders and regulators in discussions regarding findings from the Phase II investigations, the handling of contaminated materials in the project area, and other questions that arise in regard to the project.
4. Write Special Provisions and a Response Action Plan/Construction Contingency Plan for contaminated materials handling and submit to the appropriate agency.
