The “Ban Asbestos in America Act of 2007,” (S.742) was unanimously passed by the U.S. Senate on October 4, 2007 [3]. This Bill bans the importation, manufacture, processing, and distribution of asbestos-containing products that contain more than 1% asbestos by weight [3]. A similar companion Bill, H.R.3339, was also introduced in the U.S. House of Representatives on August 2, 2007, but the House Bill never moved beyond Committee deliberations and the Bill was never presented to the full House for voting [4]. Some members of the House argued that the Senate’s “Ban Asbestos in America Act of 2007” Bill does not go far enough and a revised version of the House Bill was introduced in draft form to the Subcommittee on Environmental and Hazardous Materials on February 15, 2008 [5]. The proposed House draft legislation bans products containing asbestos in any concentration. However, the draft legislation specifies an exemption limit of less than 0.25% asbestos by weight for aggregate products (extracted from stone, sand, or gravel operations) [5]. The passed Senate Bill and House draft legislation use the Toxic Substances Control Act’s (TSCA) definition of asbestos, which includes the asbestiform varieties of chrysotile, crocidolite, amosite, anthophyllite, tremolite, and actinolite. In addition, the definition of asbestos in the Senate Bill and the House draft legislation includes the asbestiform varieties of winchite and richterite, as well as any asbestiform amphibole material.
Whereas the Senate “Ban Asbestos in America Act of 2007” calls for the National Academy of Sciences (NAS), EPA, and other Federal entities to evaluate possible health effects and develop recommendations for identifying, distinguishing, and measuring non-asbestiform minerals and elongate mineral particles, the House draft legislation removes the call for these important health effect and mineral identification studies in an apparent effort to ban asbestos products as quickly as possible. However, the effects of a broader definition for asbestos on the potential cost increases on manufactured products in the United States, as well as the potential economic effects to the raw materials production, mining, aggregate, manufacturing and construction industries, is not sufficiently addressed in these Bills.
Complicating any discussion on asbestos are the many differences of opinion between the various scientific communities, health risk professionals, and regulators. Without an accepted definition for asbestos, improved sampling and analytical methods for distinguishing between asbestos and non-asbestiform elongated mineral particles; and a consensus on the relative health risks of minerals particles based on sound scientific study, the long reaching ramifications and economic impact to U.S. industrial commerce could be significant. Without further clarification of these issues, unfounded product bans and unwarranted public fears could result if this legislation is passed in its current form.
In order to fully understand the implications of the proposed House draft legislation to ban asbestos-containing products in the United States, it is recommended that everyone read and become familiar with the Senate and House versions of the “Ban Asbestos in America Acts”.

It is also recommended that concerned individuals become active in their local professional and scientific societies to stay aware of how this pending legislation will impact themselves and their specific industries. For more information, please visit the following websites:
