Asbestos Floor Tile and Roofing Materials

Waste Management logo





There have been many questions from contractors and other individuals regarding the proper handling and disposal of asbestos-containing vinyl floor covering and asphalt roofing materials. The South Dakota Department of Environment and Natural Resources (DENR) has adopted the revised National Emission Standard for Hazardous Air Pollutants (NESHAP) by reference. These federal regulations are found in 40 CFR 61, Subpart M .  Under these rules, resilient floor coverings and asphalt roofing materials are defined as Category I nonfriable materials. The term "friable" means that a material can be easily crushed or reduced to powder thereby releasing asbestos fibers into the air. Nonfriable materials, such as floor tile and asphalt roofing, are not easily crumbled and are less likely to release fibers unless mishandled.


According to the current regulations, Category I nonfriable materials are not required to be handled or disposed of as regulated asbestos materials as long as they remain nonfriable during removal and handling. Also, nonfriable materials are not required to be handled by certified asbestos workers as long as they remain nonfriable.


In order to be considered nonfriable, they must not be in poor condition or made friable by sanding, cutting, grinding or abrading. The EPA has determined that the use of power tools such as pneumatic chippers or power saws will cause these materials to become friable. If they are in poor condition or are made friable during handling then they are considered regulated if more than 160 square feet of materials are disturbed. The EPA has also determined that if a rotating blade roof cutter or similar equipment is used on asbestos-containing asphalt roofing materials, the removal of 5,580 square feet or greater will create 160 square feet of regulated asbestos material, thereby making the project subject to all of the requirements of the NESHAP rules.


Any Category I materials which are not in poor condition and are not made friable during handling can be disposed of as normal waste, but may be subject to local landfill requirements. Any friable materials exceeding 160 square feet must be handled and disposed of according to all NESHAP requirements. It should be noted that OSHA has additional regulations which may apply to any asbestos projects and the EPA has additional rules regarding asbestos in schools. The OSHA regional office number is (720) 264-6550. You may also view the OSHA regional office homepage.  As stated above, every landfill has the final approval of what types of materials they will accept and how they will accept them, so it is a good practice to check with the landfill operator prior to disposal of any asbestos-containing material.
