HS&EA Area P2 ASBESTOS COMMENTS FILE: ASBESTOS *9(0 rtf u-t dlist*-r / L. /*t Enclosed is a copy of the cover letter froir- ORC's recent submission to OSHA concerning the Notice of Proposed Rulemaking (NPR) for asbestos. Basically, ORC is recommending a dual exposure limit: Permissable Ambient Concentration (PAC) of 0.5 fibers/cc - engineering would be required to control ambient concentrations to this level. Permissabie Exposure Limit (PEL) of 0.2 fibers/cc - employee exposure greater than 0.2 fiber/cc but less than 0.5 fiber/cc would require the use or c negative pressure respirator with a high efficiency filter, capable of pi-oviding a minimum fit factor of 5 and capable of being qualitatively or quantitatively fit tested. (over3 the PAL exceeds 0.5 fibers/cc and where engineering, administrative or work practice controls are not feasible, CRC recommends the use of positive pressure supplied air or self-contained breathing apparatus. If you would like a copy of the full text of ORC's comments and recommenda tions (about 4C pages), let me know. / 7'/J-rr VC-ti: jtm: At r-a fitment Q g C 's /- --. / CaT / Richard G.
