Senate Passes "Ban Asbestos in America Act"

Nearly 7 years ago, the late Senator Paul Wellstone (D-MN) and Senator Patty Murray (D-WA) began a legislative effort to ban asbestos-containing products. Yesterday, the "Ban Asbestos in America Act" passed the Senate with a bi-partisan voice vote.

On introducing the measure, the bill's author, Senator Murray, said:

"When I heard about Americans and people who were dying from absestos, I thought to myself, my gosh, I thought asbestos was banned many years ago. How can this be? Well, the fact is asbestos has never been banned [in the U.S.], today 2,500 metric tons of asbestos are being imported every year. It is in products such as hair dryers, ceiling tiles, it is in brake pads, and over 3,000 other products Americans are using and being exposed to every day."

The bill, which must still be approved by the House, would amend the Toxic Substances Control Act (15 USC 2641 et seq) with definitions of asbestos which include

"Any material formerly classified as tremolite, including winchite asbestos; and richterite asbestos; and any asbestiform amphibole mineral."

On introducing the measure, the bill's author, Senator Murray, said...

Under the bill:

  • EPA would be required to issue regulations "prohibiting persons from importing, manufacturing, processing, or distributing in commerce abstestos-containing materials" (1 year for a proposed rule and 1 more year for a final rule)
  • CDC to establish a "mechanism by which to obtain, coordinate and provide data and specimens" from cancer registeries, the National Mesothelioma Virtual Registry and Tissue Bank, and other asbestos-related disease entities
  • NIOSH to prepare a report (within 12 months) on the "current state of science" on health effects related to non-asbestiform minerals and elongated mineral particles, methods for measuring and analyzing such materials, and recommendations for future research; and
  • NIOSH to prepare reports on "mode of action and health effects" of non-asbestiform minerals and elongated mineral particles, and sampling and analytical methods for measuring these materials.

Provisions of the Bill...

The bill contains a number of other provisions, including possible exemptions from the ban if EPA determines that

"...the exemption would not result in an unreasonable risk of injury to health or the environment, and the person has made a good faith effort to develop, but has been unable to develop, a substance (substitute)..."

or if the use of asbestos-containing materials is sought by the Defense Department or NASA.

Senator Murray offered kind words of appreciation to Senator Isakson (R-GA) who was the lead Republican sponsor of the bill.

"I began with Senator Paul Wellstone, 6 years ago to try and pass this legislation. Of course, I lost my friend Senator Wellstone in an airplane crash. I thought to myself: Wow, how am I ever going to get this out of the Senate without his passion?"

"Well, I was fortunate because I found another partner who was just as passionate, Senator Isakson from Georgia, who took up this banner with me, who has worked this bill through every way possible, because he too looked into the eyes of those families who were losing loved ones, members of their families today, because asbestos was exposing them to deadly diseases... I could not have done it without him."

Senator Isakson said:

"Banning asbestos is simply the right thing to do. This bill provides the framework for how this country must go about achieving this goal. I plan to work with my colleagues on both sides of the aisle to see it to the President's desk."

Senator Isakson said...

One of the issues that is not addressed head-on in the bill, but is the subject of further study, is how to deal with the long, thin mineral fibers that are not currently defined by OSHA as "asbestos." As Senator Isakson noted:

"One difficult issue to resolve involved the treatment of nonasbestiform minerals. These so-called 'cleavage fragments' that appear naturally and more abundantly than asbestos, are in land and dirt and are mined all across Georgia and in significant areas across the Nation. They are similar to asbestos in chemical make-up, but differ significantly in structure and many other respects. ...Our bill makes no presumption as to the health effects of nonasbestiform minerals but rather enlists the Nation's best scientists to study...to both differentiate these minerals according to the asbestos-related health risks, and distinguish between these minerals as they are identified in the natural, mixed dust environment. Asbestos, the path of its deadly health effects, the identification and differentiation of asbestos from other minerals especially in the natural mixed dust environment, are all complex areas of science and it is time for the Federal Government to pool its expertise scattered among a half-dozen agencies, to better understand the risks and how to properly identify the fibers of risk."

We may never have all the scientific evidence we need...

Ah, yes. That's the kicker. No disrespect to Senator Isakson, but I sense he's been listening to representatives of the mining industry.

We may never have all the scientific evidence we need to determine the precise level of excess risk from exposure to each different type of long, thin mineral fiber. Workers at construction sites, quarries or other mining operations can be exposed to all sorts of mixed respirable mineral fibers, and even the best epidemiologists in the world would be hard-pressed to collect enough data on these exposures and long-term health effects to make a reliable risk estimate.

Instead of suggesting that we can"study" our way out of this scientific uncertainty issue, let's assume (for public health's sake) that breathing long, thin, durable, respirable mineral fibers is not good for a workers' lungs. Employers should be required to put measures in place (like water sprays and enclosed cabs with HEPA filtered-ventilation systems) so dust exposure does not occur.

I'm all for scientific research on difficult toxicological and epidemiological issues, but not if it is used as an excuse to delay protections for workers' health and safety. I'll have my ears tuned and my eyes open for recommendations that MSHA's long-awaited asbestos rule should be delayed pending the results of the studies required in the "Ban Asbestos in America Act."

*Note: "Asbestos" in not a scientific term, but rather a commercial and regulatory term for chrysotile, amosite, crocidolite, tremolite-asbestos, anthophyllite-asbestos, and actinolite-asbestos. When health scientists, geologists and other expert federal officials began to investigate the serious health problems among residents of Libby, Montana, the contaminant-culprit which had polluted the entire town was not necessarily one of these "six regulated fibers," but instead were other long, thin, durable respirable mineral fibers (e.g., winchite, richterite) which caused equally-debilitating and deadly disease.
