Questions from employers in this region
DTW is Delta's major hub — what FAA testing applies to pilots and crew based there?
14 CFR Part 120 requires FAA anti-drug and alcohol misuse prevention programs for ALL aviation safety-sensitive employees at air carriers operating under 14 CFR Parts 121, 135, and 145. At DTW this includes: pilots and flight crewmembers, flight attendants, aircraft dispatchers, aircraft maintenance and preventive maintenance personnel, ground security coordinators, and fuelers performing safety-sensitive functions. We coordinate FAA-compliant pre-employment, random, post-accident, reasonable suspicion, return-to-duty, and follow-up collections for all airline and aviation employer programs at DTW.
The Big Three automakers all have assembly plants around Detroit — how do you manage CDL testing for their supplier networks?
Ford, GM, and Stellantis each operate multiple assembly plants in the Detroit metro, served by hundreds of Tier-1 and Tier-2 CDL supplier carriers. We maintain separate FMCSA Part 382 programs for each CDL supplier carrier employer — coordinating pre-employment surge testing and random pool management at supplier staging yards and carrier terminals throughout SE Michigan.
Detroit has three Class I railroads — NS, CSX, and CN. Can you serve all three simultaneously?
Yes. We maintain completely separate FRA 49 CFR Part 219 compliant programs for each railroad employer — Norfolk Southern, CSX, and Canadian National — with distinct random pool management, chain-of-custody records, and post-incident response for each carrier's covered-service employees and contractors in the Detroit area.
DTE Energy is headquartered in Detroit — what PHMSA testing applies to their gas distribution workforce?
DTE Energy operates PHMSA-regulated natural gas distribution infrastructure throughout Southeast Michigan. Covered-function pipeline employees — operators, maintenance workers, and emergency responders — are subject to 49 CFR Part 199 anti-drug and alcohol misuse prevention requirements. We coordinate PHMSA-compliant on-site collections for DTE Energy employees and contractors throughout Wayne, Oakland, and Macomb counties.
