DOE Differing Professional Opinions

Office of Environment, Health, Safety & Security

You are here

DOE has established a variety of work processes for its employees (including DOE Federal, contractor, and subcontractor employees) to raise concerns so that they are assessed and appropriate actions are taken. Employees are to use these processes to resolve issues at the lowest possible level. In rare cases, an employee may decide that despite those efforts, there remains a concern about a technical issue with a potential for a significant impact on environment, safety or health.

If you have a concern involving a technical issue with potential significant impact to environment, safety and health and you have tried unsuccessfully to ensure that it is adequately addressed through lower-level processes, please consider whether you should file a Differing Professional Opinion (DPO) through the DPO process discussed on this page and in DOE O 442.2 Chg 1 (PgChg), Differing Professional Opinions for Technical Issues Involving Environmental, Safety, and Health Technical Concerns. If you decide you should, please read the DPO process in the link below, complete the suggested form and the relevant information, and submit your concern to the appropriate DOE DPO Manager identified below.

Submit your DPO

  • Use the DPO submittal form to file your DPO or
