Questions from employers in this region
ORNL is the largest US DOE science and energy lab — what does DOE Order 442.1A require for contractors?
DOE Order 442.1A requires all DOE contractors and subcontractors — including UT-Battelle at ORNL and BWX Technologies at Y-12 — to maintain comprehensive drug-free workplace programs covering their entire workforce under 10 CFR Part 707. This is broader than standard DOT testing and applies to all contractor employees, not just safety-sensitive roles. We coordinate DOE-compliant collections for ORNL and Y-12 contractor employers.
TVA operates both nuclear plants and gas transmission systems — which regulations apply?
TVA nuclear plant operations are subject to NRC 10 CFR Part 26 Fitness for Duty requirements for access authorization holders — a broader panel and more rigorous program than standard DOT testing. TVA's gas transmission pipeline operations are subject to PHMSA 49 CFR Part 199 for covered-function pipeline employees. We coordinate collections meeting both NRC Part 26 and PHMSA Part 199 requirements for TVA contractor employer programs.
Y-12 handles nuclear weapons components — does that create special drug testing requirements beyond standard DOE?
Y-12 National Security Complex handles sensitive nuclear weapons components under NNSA (National Nuclear Security Administration) jurisdiction. NNSA contractor employees are subject to DOE Order 442.1A and potentially additional NNSA security requirements beyond standard DOE program standards. We coordinate with your BWX Technologies or subcontractor program manager to ensure collections meet all applicable Y-12 site requirements.
