Asbestos Contractor Licensing
Asbestos-related work requires MDH licensing
A contractor must be licensed by the Minnesota Department of Health (MDH) to perform asbestos-related work (ARW). ARW includes the work area preparation, enclosure, removal, encapsulation or maintenance of asbestos-containing material (ACM) during a project in a facility or building that equals or is greater than these amounts:
- 260 linear feet of friable ACM on pipes, (10 linear feet on pipes in residences),
- 160 square feet of friable ACM on other facility components, (6 square feet in residences) or,
- 35 cubic feet of friable ACM on or off facility components (1 cubic foot in residences).
Two other types of projects are regulated by MDH:
- Series of small projects that equals or is greater than these quantities in a calendar year; or
- Maintenance activities that equal or are greater than these quantities in a calendar year; these maintenance activities are for maintaining the equipment or building component the asbestos is located on, not maintaining the asbestos itself.
ARW also includes indoor air monitoring and clearance air sampling. Companies performing either of these activities must be licensed as an asbestos contractor if they are performing any air sampling on a regulated project.

Changes in company information
MDH should be informed of any company information changes, especially address, telephone number, fax number and e-mail address. This is important so the company can be made aware of any current information as it is released by MDH.
