DOL received nine (9) Internet Accessible SEM Website (IAS) public submittals since the last update on May 12th, 2023. One (1) of the submittals resulted in SEM profile revision.

In addition, DOL updated SEM site profiles using information obtained from case adjudication activities. These updates included adding solvent exposures to the electronic technician and instrument technician families of labor categories at the following six (6) DOE sites: Chupadera Mesa; Nevada Test Site; Oak Ridge National Laboratory (X-10); Pantex Plant; Savannah River Site; and Sandia National Laboratories-Albuquerque.

Since the SEM first became available to the public in March 2010, there have been 26 revisions of the SEM website. Prior to the release of each new version, the DOE reviews the new and revised information to ensure that no classification issues exist.
