DOT-COMPLIANT · ON-SITE EMPLOYER DRUG TESTING

Port of Portland USCG · PDX Airport FAA · BNSF/UP FRA · TriMet FTA · Oregon Marijuana Law Does NOT Cover DOT Workers
Portland sits at the confluence of the Columbia and Willamette Rivers — anchoring Oregon's most complex multi-modal DOT employer environment. The Port of Portland operates major marine terminals on the Columbia River handling grain, automobiles, and containers. Portland International Airport (PDX) is Alaska Airlines' second-largest hub and a major cargo facility for FedEx, UPS, and Amazon Air. BNSF and Union Pacific both maintain critical Portland operations — the city is a major rail gateway between the Pacific Coast and the Midwest. TriMet's light rail, bus, and commuter operations add FTA obligations. Intel's Hillsboro campus (the largest private employer in Oregon) anchors the Silicon Forest. Oregon's Measure 91 legalized recreational cannabis in 2014 — but 49 CFR Part 40 governs every DOT safety-sensitive employee regardless of state law. OnSite Employer Testing dispatches certified collectors throughout the Portland metro — port terminals, airport ramp areas, rail yards, and transit operations.
OnSite Employer Testing coordinates mobile drug testing collections at your Portland-area facility, yard, terminal, or job site. We do not operate a clinic. Review how it works or browse all locations we serve across the region.

Questions from employers in this region
Oregon legalized marijuana years ago — does that affect our PDX crew or TriMet operators?
No. Oregon Measure 91 has zero effect on federal DOT testing under 49 CFR Part 40. Marijuana positives are still disqualifying violations for Alaska Airlines mechanics (FAA), TriMet operators (FTA), BNSF engineers (FRA), and CDL drivers (FMCSA) regardless of Oregon state law.
Can you serve PDX airport ramp and cargo operations — including Amazon Air and FedEx?
Yes. We enroll PDX safety-sensitive aviation employees into FAA 14 CFR Part 120 compliant random pools and coordinate unannounced collections for all PDX carriers including cargo operators.
Do you serve TriMet under FTA 49 CFR Part 655?
Yes. FTA-compliant collections for TriMet MAX, bus, and WES safety-sensitive employees are available throughout the Portland metro.
Do you cover both BNSF and Union Pacific Portland yards?
Yes. FRA 49 CFR Part 219 post-accident, reasonable suspicion, and random collections are available for both BNSF Brooklyn Yard and UP Albina Yard crews.
