Questions from employers in this region
Davis-Monthan has the AMARG 'Boneyard' — what DOD contractor testing applies to that workforce?
AMARG (Aerospace Maintenance and Regeneration Group) contractors at Davis-Monthan — including Amentum, DynCorp, and Northrop Grumman — are subject to DOD contractor drug-free workplace requirements under FAR 52.223-6. We coordinate collections at Davis-Monthan coordinated with installation security access protocols for all active AMARG and 355th Wing contractor employers.
Raytheon Tucson makes Tomahawk and AMRAAM missiles — what security-related testing requirements apply?
Raytheon Missiles & Defense maintains strict DOD contractor drug-free workplace programs for their Tucson manufacturing workforce under FAR 52.223-6 and applicable classified contract requirements. We coordinate with your Raytheon facility security officer to arrange collector credentialing and on-site access for contractor employer program collections.
Freeport-McMoRan copper mines use large haul trucks — do those CDL operators need FMCSA testing?
CDL operators operating commercial motor vehicles over 26,001 lbs on public roads to or from Freeport-McMoRan mining facilities are subject to FMCSA Part 382 drug and alcohol testing requirements. In-pit haul truck operators on private mine property may have different regulatory status — your FMCSA compliance officer determines which employees require DOT testing. We coordinate FMCSA-compliant collections for mine CDL fleet employers.
