Miscellaneous Material




Types of asbestos containing materials

Following are the four common types of asbestos containing materials (ACMs):


Friable Asbestos

Materials with greater than 1% asbestos that when dry can be crumbled, pulverized or reduced to a powder under hand pressure.


Category I Non-Friable Asbestos

Typically packing material, gaskets, resilient floor covering and roofing products that contain greater than 1% asbestos and are in good condition.


Category II Non-Friable Asbestos

Any material with greater than 1% asbestos, excluding category I non-friable ACM, that when dry cannot be crumbled, pulverized, or reduced to powder by hand pressure.  Examples include: cementitious asbestos board, Transite ® siding, asbestos putties, asbestos sealants and adhesives.


Vermiculite Containing Asbestos

When vermiculite has been identified during assessment of the structure, the following guidelines will be observed during abatement/oversight:


Disposal Requirements

All asbestos waste shall be disposed of in a MnDOT approved landfill, scroll down to Landfills/Regulated Waste. Demolition debris landfills must not be used to dispose of any asbestos containing materials


Documentation Requirements

Copies of all shipping papers (also known as Asbestos Shipping Manifest) shall be furnished to the MnDOT Project Engineer within 10 days of the waste being shipped off the project site. If the contractor does not provide the shipping papers to the Project Engineer, the Project Engineer shall contact the contractor in an attempt to acquire them. If after 10 days the shipping papers signed by the owner/operator of the disposal site are not provided, the Project Engineer or oversight contractor shall notify the Office of Environmental Stewardship regarding the missing documentation, as they can assist in determining who to contact at the regulatory agencies.


Transportation Requirements

All friable asbestos over 1 pound in quantity must be handled as a hazardous material and transported with an Asbestos Shipping Manifest (furnished by the landfill).


All ACM with asbestos content over 1% must be transported with:


Packaging asbestos:


Vehicle Marking:


All asbestos waste materials shall be transported directly from the project site to the MPCA permitted landfill. Temporary storage of asbestos waste materials shall not be allowed.




Chloroflorocarbons (CFC's)

Regulations associated with CFC equipment can vary depending on whether the equipment is attached to the structure being demolished or not. Therefore, management of CFC equipment also varies.


Examples of Equipment Containing CFC’s

Equipment containing CFC’s includes but is not limited to the following: heat pumps, fire extinguishers, air conditioners, dehumidifiers, walk-in coolers, refrigerators, freezers and vending machines.



Disposal, Recycling and Documentation Requirements


CFC Equipment Attached to the Structure


CFC Equipment Unattached to the Structure


Transportation Requirements

There are no transportation requirements for attached or unattached CFC equipment




Polychloronatedbiphenols (PCB's)

Examples of Equipment Containing PCB’s


Disposal and Recycling Requirements


Documentation Requirements


Transportation Requirements




Examples of Equipment Containing Mercury

Equipment containing mercury includes but is not limited to the following: electrical switches (including silent switches), thermostats, gauges, batteries (may be within smoke detectors and emergency lighting), exit signs security systems, alarm systems, thermometers, barometers manometers, relays, thermocouples and the following types of lighting: fluorescent, mercury vapor, metal halide, high-pressure sodium, neon and HID (high-intensity discharge).


Disposal and Recycling Requirements

Mercury-containing products are regulated. All of these items identified in the structure or on the property must be handled and disposed of properly.


Because many of the items containing mercury are fragile, the following storage and transport procedures must be followed to ensure proper handling:


All mercury-containing items shall be recycled.  All removal and recycling shall be performed by MnDOT Approved List of Waste Contractors (DOCX).


Documentation Requirements


Transportation Requirements




Examples of Lead Sources

Sources of lead include but are not limited to the following: 


Disposal and Recycling Requirements


Lead paint chips must be disposed of as a hazardous waste through the MnDOT Approved List of Waste Contractors (DOCX). Lead bearing plates, lead pipes, and any lead bearing materials other than paint chips shall be recycled by a lead scrap recycler.


Beneficial reuse

Any materials with intact lead based paint (no peeling paint), such as steel beams, may be sold or released for reuse. Ownership transfer of materials with lead-based paint must be documented with a transfer of ownership form (PDF). Copies of the transfer form must be kept in the project file.


Other materials made out of lead, for example bridge bearing plates, may be sold for reuse. Ownership transfer of the materials must be document with the transfer of ownership (PDF) form. Copies of the transfer form must be kept in the project file.


Documentation Requirements

Encapsulated Peeling Lead Paint


Lead Paint Chips


Other Lead Bearing Materials


Transportation Requirements

Leaded Paint Chips


Other Lead Bearing Materials




Treated Wood

Examples of Treated Wood

Sources of treated wood include but are not limited to the following: creosote, pentachlorophenol. CCA (chromated copper arsenate or green treat), ACQ (alkaline copper quat), CA (copper azole), copper naphthanate, disodium octaborate tetrahydrate.


Disposal and Recycling Requirements





Beneficial reuse



Documentation Requirements

Project files must include manifests, scale tickets or transfer of ownership forms to document disposal or reuse of treated wood.


Transportation Requirements

There are no transportation requirements for treated wood materials




Hazardous or Household Hazardous Wastes (HHW)

 Examples of HHW

Examples of HHW include but are not limited to the following: oil, paint, solvent, fertilizer and pesticide that are present on residential properties. Waste materials on commercial properties cannot be managed as HHW..


Disposal, Recycling and Documentation Requirements

HHW can be disposed of by private property owners for no charge through their county HHW waste program. To accomplish this task, MnDOT should provide the home owner with the following information:


It is highly encouraged that MnDOT does everything possible to have private property owners remove and dispose of all household hazardous wastes prior to taking possession. All HHW identified in the assessment/inspection report must be removed from the house prior to demolition.


Any remaining household hazardous waste after the state takes possession must be disposed of using one of the following two methods:


Transportation Requirements


Packaging Requirements

Note: For the following section, the term “container” refers to the vessel holding the hazardous waste, which may be the original product package or other vessel. It does not refer to the U.S. DOT approved shipping container.


Any plastic or metal container with a volume less than 5.3 gallons or any size glass container must be lab packed and meet the following criteria:



All containers with a volume equal to or greater than 5.3 gallons must be transported in a UN 1A2 metal drum or 1H2 plastic drum. If the container holding the hazardous waste is already contained in either a UN 1A2 metal drum or 1H2 plastic drum, the existing container may be used for transport as long as it is structurally sound. If the container is not structurally sound, it must be overpacked in a UN 1A2 metal drum or 1H2 plastic drum.




Solid Wastes

Examples of Solid Waste

Examples of solid waste include but are not limited to the following: “white goods” such as stoves, refrigerators and window air conditioners, furniture and garbage.


Disposal, Recycling and Documentation Requirements
