J U N 2 0 ENVIRONMENTAL LTH Asbestos I/ t Ciassificafoon The Department of Health Services, (DHS) has classified friable, finely divided, and powdered wastes containing grater than one percent (1.0%) asbestos as Transport and hazardous waste. Asbestos includes chrysotile, amosite, crocidolite, tremolite, anthophyllite, and actinolite. A "friable" waste is one which can be reduced to Disposal a powder or dust under hand pressure when dry. ASBESTOS CANCER AND LUNG DISEASE HAZARD AUTHORIZED PERSONNEL ONLY! RESPIRATORS AND PROTECTIVE CLOTHING ARE REQUIRED IN THIS AREA Non -friable, asbestos -containing wastes are considered to be nonhazardous (regardless of their asbestos content), and are not subject to regulation under Title 22, Division 4, Chapter 30 of the California Code of Regulations (CCR). The management of such wastes remains subject to any requirements or restric- tions which may be imposed by other regulatory agencies operating under separate authority. The DHS classification standard is found in Section 66699 of Title 22, CCR. Asbestos is not presently regulated as a hazardous waste under the Resource Conservation and Recovery Act (RCRA), and therefore, is considered to be a "non-RCRA" waste. Testing for asbestos in bulk samples must be done using the polarized light microscopy method described in the Federal Register, Volume 47, Number 103, Appendix A, pages 23376-23389, May 27, 1982 (also published in Title 40, Code of Federal Regulations (40 CFR), Part 763 as "Appendix A to Subpart F - Interim Method of the Determination of Asbestos in Bulk Insulation Samples". Asbestos quantitation is performed by a point -counting procedure or equivalent estimation method. Point -counting provides a determination of the area percent asbestos. Reliable conversion of area percent to percent of dry weight is not feasible unless the specific gravities and relative volumes of the materials are known. Pursuant to Section 25198(a) of the California. Health and Safety Code, testing for any purpose under the Hazardous Waste Control Law must be performed by laboratories which are certified for hazardous waste testing according to the requirements and procedures of Article 33, CCR. The Department certifies laboratories for bulk asbestos testing, but does not certify laboratories for air testing at this time. Current costs for bulk asbestos testing range from $25 to $100 per sample. The average cost is $50 per sample.
