Asbestos abatement and removal

The assessment process identifies and documents any asbestos containing materials and other regulated materials present in structures or on the property. The assessment is also used to determine what regulated materials must be removed from the structure prior to demolition or relocation of the structure. Abatement is the process of removing asbestos containing materials. MnDOT policy requires that an approved, independent contractor oversee the actions of the contractor performing the asbestos abatement and/or removal of other regulated materials.

 

Who performs the work?

Contractors that perform asbestos abatement, removal of other regulated materials and oversight activities must be selected from the MnDOT certified contractors list, 19.1-19.5 (PDF). Contact the MnDOT Office of Environmental Stewardship Mark Vogel for information on approved contractors. The approved contractors possess required licenses and are aware of MnDOT policies regarding management of asbestos and other regulated materials.

 

 

Building demolition and relocation

Procedures for asbestos abatement and regulated material removal can vary depending on the type of structure, if the structure is being demolished or relocated and if the regulated materials are being disposed of or reused

 

 

Demolitions

Asbestos abatement and other regulated material removal

MnDOT policy requires contractors to follow specific procedures in handling and disposing of asbestos containing materials and other regulated materials in addition to complying with federal and state regulations. These additional requirements are necessary to further ensure full regulatory compliance and to lessen the department’s liability associated with management of regulated materials. MnDOT policy requires that any asbestos containing material with greater than 1% asbestos content must be abated by a Minnesota Department of Health licensed asbestos abatement contractor, regardless of whether the material is friable or non-friable

 

For buildings

All asbestos must be abated and regulated waste/materials removed from the building and the entire property under the direction of the MnDOT Office of Environmental Stewardship personnel prior to demolition of the building.

 

For bridges

All asbestos must be abated and regulated waste/materials removed just prior to demolition of the bridge to the extent practicable. Any asbestos or regulated materials that cannot be removed prior to bridge demolition can be removed during demolition. For asbestos abatement, MnDOT Office of Environmental Stewardship personnel will hire an oversight contractor to oversee the abatement process and the demolition contractor will hire a MnDOT certified asbestos abatement contractor to perform the abatement. The asbestos abatement contractor will provide all paperwork to the oversight contractor for the final report. Processes used for removal of other regulated materials or waste will be determined between the MnDOT Project Engineer and the demolition contractor. Notification requirements differ depending on the quantity and type of ACM present in a structure. Demolition of any structure, even if ACM is not present, still requires notification.

 

 

Relocations

Federal and state regulations are applicable to structure relocations. How to prepare a structure for relocation in accordance with regulations and additional precautionary measures to lessen MnDOT's liability can vary depending on the nature of the materials in the structure. Therefore, the Office of Environmental Stewardship should be contacted for assistance in managing asbestos and regulated materials associated with relocation of a structure. Homes owned by MnDOT  will be sold by MnDOT Right-of-Way personnel working with the Office of Environmental Stewardship.

 

All friable asbestos and all spray-on ceilings with ACM must be removed before a structure is relocated. Some non-friable Category II ACM (examples include Transite shingles and siding) may be left in-place if the material is in good condition and will not be disturbed during relocation of the structure. If both of these conditions cannot be met, the ACM must be removed before relocation of the structure. The Office of Environmental Stewardship should be contacted for assistance in determining what Category II asbestos containing materials should be removed for relocation projects. Similarly, Category I (examples include flexible floor coverings, asbestos tile) are not required to be removed if the material is in good condition and if the material is not expected to become friable during the move.

 

The prospective buyer must be notified if the structure contains asbestos materials or lead-based paint prior to acquisition. The contract used in selling the structure can serve as the notification document, informing the buyer of the presence of any asbestos containing materials or other regulated materials present in the structure. Contact Jane Lee with MnDOT Metro District Land Management for current contract language.

 

 

Report templates

The ACM abatement and removal process of other regulated materials must be documented in a report. The report must be kept in the project file. Reports should be prepared in general accordance with the following templates:
