Is asbestos always disposed of as Hazardous Waste? - ANSWER-No. Non-friable ACM waste is considered
non-hazardous asbestos waste. Friable ACM waste is considered a non-RCRA hazardous waste in
California.
If a friable material contains 0.5% asbestos by weight, confirmed by point count, does it have to be
disposed of as a non-RCRA hazardous waste? - ANSWER-No. It is not considered an asbestos-containing
material by NESHAP or DTSC so it can be disposed of as general construction waste. Since CalOSHA
regulates any exposure to asbestos CalOSHA regulations will still apply.

tort.

subsection (f)(3) of 8 CCR 1529 reveals that employee exposures, as indicated by statistically reliable
measurements, are below the permissible exposure limit and excursion limit the employer may
discontinue monitoring for those employees whose exposures are represented by such monitoring.
True/False. A contractor can cease personal air sampling for class 1 and 2 work with a negative exposure
assessment? - ANSWER-True
At what level of exposure does CalOSHA regulate exposure to asbestos? - ANSWER-Any level of asbestos
