Gentlemen, please complete your updates by end of April at the latest as we on currently on track to issue the final standard by at least mid-May. Yes the attachment in your note is the latest version that was provided to the HSE Panel. I propose we delete Appendix 3 from this document as we will address benzene exposure and biomonitoring in more specific technical guidelines being developed. Is that agreeable? I propose we eliminate the 2 step approach OEL and document only the TLV value to be consistent with the OS standard. is that agreeable? I will coordinate one final review of the updated document by end of April, early May. -----Original Message----From: De Jong, Geert G SI-SHS Sent: Wednesday, March 29, 2006 11:52 PM To: Ransdell, Jerry D SHLOIL-SHOIL-SHS Cc: Clegg, Patsy M SCC-DCSj22; Keulemans, Rob LW SI-SHS; Niven, Karen SI-SHS; Boogaard, Peter J SI-SHS; Margary, Alison SA SI-SHS; Cagen, Stuart Z SHLOIL-SHOIL-SHS; Clarke-Sturman, Anthony J SIPC-DSXj31; Tsai, Shan P SHLOIL-SHS Subject: Update of the "benzene briefing note" Jerry, With the pending finalisation of the benzene OEL we need to make sure that the background information which has led to the revised OEL is up-to-date.
