IMA-NA Comments on Asbestos Consultation Document

Posted By Mark Ellis, Friday, June 2, 2017

The Industrial Minerals Association – North American (IMA-NA) filed comments on Canada’s Consultation Document on the proposed regulatory approach to prohibit asbestos and products containing asbestos published on April 20, 2017 (Consultation Document).  The comments note with approval risk management decisions implemented by various governments.  The comments go on to address the scope of the Consultation Document and its approach to the generic and non-mineralogical term “asbestos.”  IMA-NA stressed the importance of applying sound science in a clear fashion to ensure that common rock fragments and soil are not mistakenly included in any regulation ultimately adopted.  To avoid this unintended outcome, the comments highlighted the importance of using Chemical Abstract Service Registry Numbers to identify with specificity the “asbestos” minerals to be covered.  The comments close by expressing support for the proposed general exemption in the regulations of naturally occurring traces of asbestos.

Responses to the Consultation Document will help inform regulations anticipated to be proposed by Environment and Climate Change Canada and Health Canada in December 2017.

The comments, without the attachments, are posted below.

NIOSH Workshop on Elongate Mineral Particles

Posted By Mark Ellis, Monday, May 1, 2017

The National Academies of Sciences Committee on Earth Resources will host a workshop on elongate mineral particles (EMPs) on May 15 and 16 in Washington, DC.  The workshop is sponsored by the National Institute for Occupational Safety and Health (NIOSH) and will address terminology and characterization of elongate mineral particles.  Asbestos fibers are a subset of a larger universe of EMPs, which encompass a broad group of respirable mineral particles of certain aspect ratios. Advancing research and communication about EMP properties and their potential health effects is challenging for a number of reasons including the continued use of inconsistent nomenclature and inadequate characterization of EMPs. One industry concern is the potential for mischaracterizing other EMPs as asbestos fibers, absent comparable mineralogy or asbestos-related health effects.  Participation in the Workshop is either in person or via WebEx.  To register for the Workshop, click here.

IMA-NA Comments on EPA Risk Evaluation for “Asbestos”

Posted By Mark Ellis, Thursday, March 16, 2017

IMA-NA filed comments with the U.S. EPA to help establish the scope of risk evaluations under development for ten chemical substances designated for priority risk evaluation under the recently reformed Toxic Substances Control Act, specifically relative to “asbestos.”  EPA asked the public for assistance in identifying information related to conditions of use (i.e., intended, known or reasonably foreseen uses) that would assist the Agency in identifying potential exposure scenarios (pathways, routes and populations).  “Asbestos” is a generic term, referring to certain silicate minerals of a particular chemistry and crystalline growth habit, in contrast to certain common silicate minerals with the same chemical formula but a nonasbestiform growth habit.  IMA-NA stressed adherence to good mineral science and urged EPA to focus of its risk evaluations for “asbestos” on the six regulated forms of commercial asbestos.  Evidence that EPA placed in the record to support the scope of its risk evaluations misstated that certain products contained asbestos, when they in fact contained the nonasbestiform analog.

IMA-NA’s comments are posted below.
