A demolition project that contains any amount of asbestos-containing materials, regardless of quantity, must comply with Wisconsin Administrative Code NR 447 and federal asbestos NESHAP regulations. Residential structures and apartments with four or fewer units are included if the demolition is part of a Wisconsin Department of Transportation road project, commercial or industrial development, or urban renewal project. However, a single, isolated residential unit with four or fewer units is exempt, unless it is part of a larger project involving multiple structures or nonresidential buildings. Demolitions planned simultaneously or within the same schedule are considered part of a larger project. For a renovation or asbestos abatement project to fall under DNR asbestos regulations, it must involve at least 260 linear feet of pipe insulation, 160 square feet (or 5,580 total square feet) of asphalt roofing removed with a roofing saw, or 35 cubic feet of asbestos-containing material from facility components.

The quantity of regulated asbestos containing materials to be removed must be at least:

• 260 linear feet of pipe insulation;
• 160 square feet, or 5,580 square feet of total area, of asphalt roofing removed with a roofing saw; or
• 35 cubic feet off of facility components (this measurement should only be used if there is no way to determine the amount as it existed on a facility component pipe, ceiling, floor, etc.)

Our administration team has the experience and attention to detail to process asbestos abatement project related paperwork and notices within required time periods and exact to regulation.
