Are you looking to renovate or modify an older house or business and think there may be asbestos containing materials (ACM)?  Did you know that homes built after the 1990's also have asbestos containing materials in them. Due to excessive hurricanes destroying many homes in the south, drywall and other building materials were imported from other countries and installed without being checked for asbestos.

Asbestos is a naturally occurring, fibrous silicate minerals mined throughout the world for its unique properties, such as; thermal insulation, chemical and thermal stability, and high tensile strength. Asbestos is commonly used as an acoustic insulator, thermal insulation, fire proofing and in other building materials. In addition to being mined, asbestos can be found naturally in the air outdoors and in some drinkable water.

National Emission Standards for Hazardous Air Pollutants (NESHAP)

Asbestos was one of the first hazardous air pollutants regulated under the air toxics program. On March 31, 1971, EPA identified asbestos as a hazardous pollutant, and on April 6, 1973, EPA promulgated the Asbestos NESHAP, currently found in 40 CFR Part 61, Subpart M.  NESHAP has been amended several times, most comprehensively in November 1990. In 1995, the rule was amended to correct cross-reference citations to OSHA, DOT, and other EPA rules governing asbestos.

NC Regulations
The Health Hazards Control Unit (HHCU) of the N.C. Department of Health & Human Services, Division of Public Health, must be notified of plans to demolish a building, including residences demolished for commercial or industrial expansion. Owners or operators must obtain an asbestos removal permit from the HHCU prior to any renovation project that will disturb more than 35 cubic feet, 160 square feet, or 260 linear feet of regulated asbestos-containing material

Common areas in the home where asbestos can be found include:

  • Steam pipe wraps, boilers and wraps, furnace ducts
  • Resilient floor tiles, vinyl flooring and mastic (glue)
  • Ceramic tile, and grout
  • Vinyl base cove and glue
  • Carpet glue
  • Cement Sheet, millboard
  • Door gaskets, caulk
  • Soundproofing or decorative material (ceiling tiles)
  • popcorn textured ceilings
  • Wallboard, patching and joint compound
  • Cement roofing, shingles, tar, caulk, and siding
  • Insulation

Asbestos exposure is a health concern when high concentrations of asbestos fibers are inhaled over a long period of time.  If asbestos material is disturbed it may release asbestos fibers, which can be inhaled into the lungs. After inhaled, asbestos fibers can remain and accumulate in the lungs, which over time may cause serious lung diseases including: asbestosis, lung cancer, or mesothelioma. Remodeling or demolition activities including cutting, sanding, or disassembling can disturb asbestos fibers and release the fibers into the air. In addition, it may convert to a building material that is crumbly and easily ground up with your hand.

 DRH can assist you with getting the information you need to submit to permitting and the HHCU for a renovation or demolition project . DRH visually inspects and collects samples according to the clients requests or according to EPA, NESHAP, and AHERA regulations.
