asbestos -- Public Workshop to Discuss Potential Revisions to Test Method 435 Posted: 24 Dec 2007 10:29:49
The California Air Resources Board (ARB) staff invite you to participate in the first workshop to discuss potential revisions to Test Method 435 – Determination of Asbestos Content in Serpentine Aggregate. This test method is referenced by two ARB airborne toxic control measures (for surfacing applications and for construction, grading, quarrying, and surface mining operations) that aim to limit public exposure to naturally-occurring asbestos. You are receiving this notice because you are a subscriber to the Naturally-Occurring Asbestos list serve. You may have been added by ARB staff because your name appeared on past email lists regarding naturally-occurring asbestos. Directions to unsubscribe appear below. The purpose of this first workshop will be to discuss staff’s rationale for modifying the test method as well as to discuss potential areas of Test Method 435 to be revised. Staff’s proposed revisions will only focus on the laboratory sample preparation and analytical portions of the test method. In addition, the two airborne toxic control measures are not being considered for revision. The workshop notice can be found at: http://www.arb.ca.gov/toxics/asbestos/tm435/workshops/wrkshp1.pdf Interested parties can follow activities related to this method modification process at the newly created Test Method 435 homepage: http://www.arb.ca.gov/toxics/asbestos/tm435/tm435.htm You will receive another list serve notice when the workshop agenda is posted on the homepage (approximately one week prior to the workshop). The agenda will include conference calling instructions for those who want to participate but are unable to attend in person. If you have questions about the public workshop or the method modification process, please contact Rebecca Neumann at (916) 324-1145 or via email at firstname.lastname@example.org. Thank you.
