Current - September 2008

The latest version, Revision 24, of the Protective Action Criteria/ Temporary Emergency Exposure Limits (PAC/TEEL) data set is scheduled to be released this month. It will be provided as on-line database, Excel workbook, and as formatted tables (pdf files). See our PAC/TEEL webpage for links to these products. Revision 24 has been updated to include Final or Interim 60-minute Acute Exposure Guideline Levels (AEGLs) and Emergency Response Planning Guidelines (ERPGs) through June 2008. PAC values, including AEGLs, ERPGs, and Temporary Emergency Exposure Limits (TEELs), are now provided for 3356 chemicals.

A new version of the Chemical Mixture Methodology data set is also scheduled to be released this month. It will incorporate Health Code Numbers (HCNs) for all chemicals in the PAC/TEEL data set through Revision 23 and may even incorporate all the chemicals through Revision 24. Our CMM development team (Rocky Petrocchi, Xiao-Ying Yu, Donna Trott, and Jayne-Anne Bond) has worked tirelessly over the summer to bring the CMM data set up to date by developing HCNs for about a thousand chemicals. A special acknowledgment goes to Donna Trott, our Pacific Northwest National Laboratory graduate intern, who has done an outstanding job developing HCNs. See our CMM webpage for a link to the CMM Excel workbook and documentation products.

We are pleased to report that SCAPA member Dave Freshwater has been awarded the prestigious F. Tom Roberts Memorial Volunteer Award by the rail safety group Operation Lifesaver.

The 2009 annual EMI SIG and SCAPA meetings will be held May 4-9, at the InterContinental Mark Hopkins Hotel. The main, one-day-long SCAPA meeting will be held on Thursday, May 8th. There will also be a busy schedule of SCAPA working group meetings on Monday, May 5th through Wednesday, May 7th.
