Date: Fri, 28 Apr 2017 17:24:25 -0700 Subject: asbestos -- Asbestos Test Method 435 Implementation Guidance Document Finalized From: rneumann@arb.ca.gov The California Air Resources Board (ARB or Board) announces the release of the Implementation Guidance Document for Test Method 435 Field Sampling and Laboratory Practices. This guidance document is intended to be used in conjunction with Test Method 435 (M435) (Cal. Code Regs., tit. 17, § 94147), entitled “Determination of Asbestos Content of Serpentine Aggregate,” to assist laboratories, consultants, local air pollution control districts, and other asbestos stakeholders in the application and performance of M435. Asbestos content measurement using M435 is required by the Asbestos Airborne Toxic Control Measure (ATCM) for Surfacing Applications (Cal. Code Regs., tit. 17, § 39106), and is recognized as an approved test for asbestos content in bulk materials for the Asbestos ATCM for Construction, Grading, Quarrying, and Surface Mining Operations (Cal. Code Regs., tit. 17, § 39105). The M435 Implementation Guidance Document can be found at: http://www.arb.ca.gov/toxics/asbestos/tm435/guidancedocument.pdf This guidance document was written to address reports of variable M435 results from analyses of the same samples by different laboratories. This guidance document consists of clarifications and recommendations developed by ARB staff through years of method testing of M435 procedures and iterative consultation with many asbestos stakeholders. It is expected that using the guidelines in this document during the collection, processing, and analysis of potential asbestos-containing aggregate samples will result in more accurate and repeatable M435 asbestos content measurements. Questions regarding this document can be sent via email to Rebecca Neumann at rebecca.neumann@arb.ca.gov or by mail to: Air Resources Board Monitoring and Laboratory Division P.O. Box 2815, Sacramento, CA 95812 Attention: Rebecca Neumann For additional information on M435, please visit the Test Method 435 homepage at: http://www.arb.ca.gov/toxics/asbestos/tm435/tm435.htm ====================================================================== You are subscribed to the asbestos mailing list.
