SEM Updated the week of November 16, 2017

The Site Exposure Matrices (SEM) website has been updated! This update makes the website current through November 16, 2017. New information is now available for 24 DOE sites including the Mound Plant, DeSoto Avenue Facility, Idaho National Laboratory, Savannah River Site, and the Tonopah Test Range.

DOL received 40 public submittals related to toxic substances and diseases since the last update on May 16, 2017. Those submittals resulted in 11 SEM revisions including updates of the SEM profiles for Area IV of the Santa Susanna Field Laboratory and the Oak Ridge National Laboratory. At the suggestion of a member of the public, DOL started reviews of the labor categories in the Department of Energy’s Comprehensive Epidemiologic Data Resource (CEDR). Since May 16, 2017, reviews of CEDR have been completed for six (6) DOE sites. The SEM profiles of each of those sites were updated with the results, including the Ames Laboratory, Kansas City Plant, and the Feed Materials Production Center.

Information provided by the DOL District Offices was used to update SEM data for six DOE sites including the Los Alamos National Laboratory, Portsmouth Gaseous Diffusion Plant, and the Canoga Avenue Facility. A closure profile was developed and added to SEM for the Mound Plant to provide toxic profiles for workers involved with decommissioning, decontamination, demolition and related activities.

Since the SEM first became available to the public on March 2010, there have been fourteen 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.
