Asbestos Abatement, Removal, & Transport
Asbestos Abatement (removal, remediation) is the procedure to control fiber release from asbestos-containing materials in a building or to remove them entirely, including removal, encapsulation, repair, enclosure, encasement, and operations and maintenance programs.
Transporter is the hauling company that picks up properly packaged and labeled hazardous waste from its generators and transports it to designated facilities for treatment, storage, or disposal. Transporters are subject to EPA and DOT hazardous waste regulations.
Asbestos Containing Materials (ACM's)
Asbestos containing materials commonly removed or abated from residential and commercial buildings are;
Vermiculite: a naturally occurring mineral composed of shiny flakes, resembling mica. Expanded vermiculite is a light-weight, fire-resistant, and odorless material and has been used in many commercial and residential products, including insulation for attics and walls. A mine near Libby, Montana, was the source of over 70 percent of all vermiculite sold in the U.S. from 1919 to 1990. There was also a deposit of asbestos at that mine, so the vermiculite from Libby was contaminated with asbestos. Vermiculite from Libby was used in the majority of vermiculite insulation in the U.S. and was often sold under the brand name Zonolite.
Flooring: many types of flooring, including sheet vinyl, vinyl or asphalt floor tiles and any associated paper-like backing, mastic, adhesive or glue, may contain asbestos. In the past, asbestos fibers were added during the production of flooring materials to strengthen the flooring and to increase its durability.
Popcorn Ceiling: also known as an acoustic ceiling with its bright white "cottage cheese" texture, often contained asbestos. Popcorn ceiling was typically a spray-on or paint-on ceiling coating used from the late 1950s into the 1980s in residential and commercial construction. It could be quickly and easily sprayed on in new construction and was also useful in masking ceiling defects in older homes, such as stains, uneven ceilings or poor workmanship.
Siding: Asbestos siding was often used in buildings and homes built around the 1920s to the 1970s, and can still be found in many older homes in the US and Canada. Asbestos siding (also called asbestos cement or transite siding) was typically made by adding asbestos to Portland cement, which was then pressed into siding shingles that came in a wide variety of sizes, profiles, and textures.
Roofing: Roofing materials that contain asbestos have been used in a wide variety of homes and commercial buildings since the early 1900s. Examples of roofing materials that may contain asbestos are; asphalt shingles, composition shingles, tar, roofing felt (tar paper), roof cement, etc.
Drywall: Drywall containing asbestos is a possibility in residential and commercial buildings constructed before the 1980s. Drywall, drywall tape, and the joint compounds that were used with drywall often contained high levels of asbestos. As recently as the early 21st century drywall products containing asbestos were imported into the United States.
Heating Systems: Boilers, furnaces, heating and cooling ducts may contain asbestos (thermal system insulation). Asbestos was commonly used in the manufacture of heating and cooling ducts. The material was used to line the inside and outside of the pipes and duct work in both residential and commercial construction.
Landfills: An asbestos landfill is a waste landfill that has one or more areas designated for the disposal of asbestos containing materials. The operation and maintenance of an asbestos landfill requires compliance with strict guidelines in order to avoid release of asbestos.
Transport & Disposal: Once asbestos has been removed, federal regulations dictate that such waste be disposed of in an approved manner.
