Questions from employers in this region
PHX is a major American and Southwest 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 PHX 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 PHX.
The TSMC and Intel fab construction in Phoenix is enormous — how do you handle CDL testing for mega-construction projects?
TSMC Fab 21 and Intel Fab 52/62 represent some of the largest US construction projects in decades, involving hundreds of CDL and heavy equipment operators from dozens of prime and subcontractor employers. We coordinate separate pre-employment and random testing programs for each contractor employer tier — Hensel Phelps, Whiting-Turner, and their subcontractors — maintaining distinct chain-of-custody records per employer.
Southwest Gas is headquartered in Phoenix — what PHMSA coverage do they have across Arizona?
Southwest Gas Corporation operates one of the largest natural gas distribution systems in the Southwest, covering Arizona, Nevada, and California. Covered-function pipeline employees throughout their Arizona distribution territory are subject to PHMSA 49 CFR Part 199. We coordinate PHMSA-compliant on-site collections for Southwest Gas employees and contractors at facilities throughout the Phoenix metro and across Arizona.
Does Arizona have specific drug testing laws that affect employer programs?
Arizona Revised Statutes § 23-493 et seq. establishes a framework for employer drug testing programs, including employee rights, testing procedures, and confirmed positive result requirements. For DOT-regulated employees, federal requirements preempt Arizona state law. For non-DOT employees, the Arizona statute sets baseline procedural requirements. We coordinate collections that satisfy both federal DOT and Arizona state program requirements.
