On-site DOT-compliant collections at the Port of Duluth-Superior — the largest Great Lakes port by tonnage — Canadian National and BNSF taconite ore dock rail operations, and Twin Ports maritime and warehousing employers.

Questions from employers in this region
Can you test at the Port of Duluth-Superior without disrupting ore dock loading?
Yes. We stage collections at terminal gates, dock offices, and designated on-site locations at Duluth-Superior bulk terminals — minimizing turn time for drayage CDL drivers while meeting FMCSA Part 382 chain-of-custody requirements during taconite, grain, and coal loading seasons.
Our employer has workers in both Duluth, MN and Superior, WI. Do testing requirements differ across the harbor?
Federal DOT regulations (49 CFR Parts 40, 382, 219) apply uniformly on both sides of the harbor for regulated employees. For non-DOT company-policy programs, Minnesota and Wisconsin have different state-level notice and procedural requirements. We coordinate collections on both sides of the Twin Ports and can address multi-state program questions.
How quickly can you reach a CN or BNSF ore dock for an FRA post-incident test in Duluth?
We target on-site arrival within 2 hours for post-accident or reasonable-suspicion collections at CN and BNSF Duluth-area rail facilities. Call (219) 315-0345 immediately for emergency dispatch — FRA post-accident testing has mandatory time windows that cannot be missed.
