SEM Updated the week of January 20, 2020

The Site Exposure Matrices (SEM) website has been updated! This update makes the website current through November 15, 2019. New information is now available for 25 DOE sites including the initial SEM closure profile for Area IV of the Santa Susanna Field Laboratory and profiles of Depleted Uranium Hexafluoride Conversion Facilities at the Paducah and Portsmouth Gaseous Diffusion Plants. Significant additions were also made to the Idaho National Laboratory, Lawrence Livermore National Laboratory, Los Alamos National Laboratory, and the Rocky Flats Plant profiles.

DOL received 19 public submittals related to toxic substances and disease inputs since the last update on May 10, 2019. Two of those submittals resulted in revisions of the SEM profiles for the Y-12 Plant and the Portsmouth GDP. DOL reviews of the labor categories in the Department of Energy’s Comprehensive Epidemiologic Data Resource (CEDR) continued and were completed for the Rocky Flats Plant.

Information provided by the DOL District Offices is also being used to update SEM. Changes were made to the SEM profiles of the following four DOE sites: Brookhaven National Laboratory, Hanford/PNNL, Mound Plant, and the Nevada Test Site.

Since the SEM first became available to the public in March 2010, there have been 18 revisions of the SEM website. Prior to the release of each new version, the US Department of Energy (DOE) reviews the new and revised information to ensure that no classification issues exist. If necessary, changes are made. For this most recent version, no changes were required.
