Assessment guidelines
Prior to demolition or relocation of a structure, a regulated waste assessment must be performed by a MnDOT approved contractor (PDF) and an assessment report written. The assessment should include the entire parcel and not just the structure, as regulated wastes such as treated wood (used for landscaping) can be present at the project site that are not associated with the structure. The assessment report must adhere to MnDOT report requirements and:
- Identify the presence or absence of regulated wastes; document the structure, the type, location and amount of each waste material found at the structure.
- Be completed by a certified hazardous material manager who is also an asbestos inspector certified with the Minnesota Department of Health.
- Be provided to the MnDOT Project Engineer and the MnDOT Office of Environmental Stewardship.
The following regulated wastes must be addressed in the assessment process (follow the link provided for each waste type for examples of typical products containing the waste):
- Asbesto containing materials (both friable and non-friable)
- Chlorofluorocarbons (CFC’s)
- Lead
- Mercury
- Polychlorinated Biphenyls (PCB’s)
- Treated wood
- Other regulated wastes on the premises such as waste paints, pesticides or solvents or other chemicals identified during the assessment process that may have been abandoned by the previous owner.
- Other solid wastes such as white goods (appliances) and trash.
Contractors retained to perform assessment of structures for asbestos containing materials or other regulated materials must be selected from the approved list of contractors (PDF). Contact Mark Vogel with the Office of Environmental Stewardship for more information on MnDOT approved contractors.
