Questions from employers in this region
PHL is a major American Airlines 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 PHL 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 PHL.
What FTA testing requirements apply to SEPTA operators in Philadelphia?
49 CFR Part 655 requires FTA-funded transit agencies like SEPTA to maintain anti-drug and alcohol misuse prevention programs for safety-sensitive employees — including vehicle operators, maintenance personnel, controllers, and security officers. SEPTA's bus, rail, and subway operators are subject to pre-employment, random, post-accident, and reasonable-suspicion testing. We coordinate FTA-compliant on-site collections for SEPTA contractor and operator employer programs.
Philadelphia Gas Works is the largest municipal gas utility in the US — what PHMSA requirements apply?
PGW operates PHMSA-regulated natural gas distribution infrastructure throughout Philadelphia. Covered-function 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 PGW employees and contractors at depots and field staging locations throughout the city.
