The Department of Health and Human Services, specifically the Centers for Disease Control and Prevention (CDC), is seeking qualified contractors to assist with dose reconstruction and related activities under the Energy Employees Occupational Illness Compensation Act (EEOICPA). The primary objectives include conducting approximately 3,120 dose reconstructions annually, evaluating Special Exposure Cohort (SEC) petitions, and providing technical and program management support, all while adhering to strict privacy and security standards. This opportunity is critical for fulfilling NIOSH's obligations in supporting claims and ensuring accurate assessments of occupational exposure. Interested parties are encouraged to submit their capability statements and feedback on the draft Performance Work Statement (PWS) by contacting H. Dale Bish at uwo8@cdc.gov or Taylor Wellman at xur0@cdc.gov, as the government is currently in the sources sought phase and not yet soliciting proposals.
