Questions from employers in this region
What is DOE Order 442.1A and how does it differ from standard DOT drug testing?
DOE Order 442.1A is the Department of Energy's contractor drug-free workplace directive — it requires all DOE contractors and subcontractors to maintain comprehensive drug-free workplace programs including testing, employee assistance, and supervisory training. It is broader than standard DOT testing and applies to the full contractor workforce at DOE sites like Portsmouth, not just safety-sensitive regulated roles. We coordinate collections that meet DOE Order 442.1A and 10 CFR Part 707 documentation requirements.
DOE Portsmouth has strict site security — can you coordinate collector access for D&D contractor testing?
Yes. We coordinate with your DOE contractor security office and program manager (FBP, Centerra, or Amentum) to arrange collector credentialing and site access under DOE Portsmouth security protocols. All collections are documented to DOE Order 442.1A chain-of-custody standards.
Portsmouth is in rural Southern Ohio — is there a clinic nearby, or is on-site the only option?
The nearest major clinic network to the DOE Portsmouth Site in Pike County is 20—40 miles away. For DOE D&D contractor employers and CDL construction employers in Scioto, Pike, and Gallia counties, on-site mobile testing is the only practical solution for maintaining compliant, timely collections.
