Questions from employers in this region
Tilden Mine is one of North America's largest iron ore operations — what CDL testing applies to mine fleet employees?
CDL operators transporting iron ore, pellets, and mining materials on public roads in commercial motor vehicles over 26,001 lbs are subject to FMCSA Part 382 drug and alcohol testing. Tilden Mine's large CDL haul fleet and incoming supply vehicles require pre-employment, random, and post-accident testing. We coordinate on-site testing at mine staging areas and CDL dispatch locations in Marquette County.
The Upper Peninsula is extremely remote — is there any clinic within practical distance of Marquette mining operations?
For most Upper Peninsula mining and construction employers, the nearest major testing clinic network is either in Marquette itself or over an hour away in the Lower Peninsula. On-site mobile testing is the only practical compliance solution for remote UP employers — we come to your mine site, utility yard, or construction staging area.
