Rivian EV factory. GROWMARK agricultural logistics. I-55 / I-74 freight corridor. Collections at your facility.
Bloomington-Normal sits at the intersection of I-55 and I-74 — two major freight arteries connecting Chicago to St. Louis and Indianapolis. Rivian Automotive operates a 3.3-million-square-foot electric vehicle manufacturing facility in Normal with approximately 7,700 employees. GROWMARK, an agricultural cooperative serving nearly 400,000 customers across North America with agronomy, energy, logistics, and grain hauling operations, is headquartered here. The I-55 / I-74 corridor generates consistent demand from FMCSA-regulated carriers, construction contractors, and manufacturing employers throughout McLean County.
OnSite Employer Testing coordinates mobile and on-site drug and alcohol testing for Bloomington-Normal employers — Rivian production contractors, GROWMARK fleet drivers, and logistics carriers serving the central Illinois freight corridors. We travel to your facility. See how it works and all locations.
Rivian Normal — EV Manufacturing Contractor Testing
Rivian's Normal assembly plant is one of the largest EV manufacturing facilities in North America. With 7,700 employees and ongoing production expansion, the facility supports a large contractor and subcontractor ecosystem — trades workers, maintenance contractors, logistics personnel, and CDL drivers delivering components or hauling finished vehicles.
Manufacturing contractors accessing Rivian's facility are commonly required by their contract agreements to maintain a drug-free workplace program including pre-employment screening for all employees with facility access. CDL drivers delivering to or from the plant are FMCSA-regulated and require full DOT random programs. We serve both populations — plant-access contractors needing Non-DOT pre-employment screening and the carrier ecosystem needing ongoing DOT compliance.
GROWMARK — Agricultural Cooperative Fleet Testing
GROWMARK operates one of the largest agricultural logistics networks in North America from its Bloomington headquarters. The cooperative's FS-brand member network hauls grain, agricultural chemicals, fertilizer, and fuel across Illinois and beyond — fleets that include hazmat-rated CDL vehicles subject to FMCSA and PHMSA testing requirements.
GROWMARK's member co-operatives and affiliated carriers require pre-employment and random DOT testing for drivers hauling regulated commodities. We coordinate mobile collections at cooperative facilities, grain elevators, and terminal locations across central Illinois.

Questions from employers in this region
We are a contractor working inside the Rivian plant in Normal. Do we need drug testing?
Many contractors accessing Rivian's facility are required by their contract agreements to maintain a drug-free workplace program including pre-employment screening for all employees with facility access. We provide pre-employment Non-DOT drug testing with fast turnaround — typically 24–48 hours for a negative result — and coordinate directly with your HR team for new hire onboarding.
GROWMARK grain haulers — are they DOT-regulated even for local runs?
Yes. FMCSA regulations apply to all CDL drivers operating commercial motor vehicles in interstate commerce regardless of distance. For PHMSA-regulated hazmat loads (fertilizer, agricultural chemicals, fuel), additional testing requirements apply. We ensure your drivers are enrolled in the correct program for their commodity and vehicle class.
We have both FMCSA drivers and Non-DOT warehouse workers at the same facility. Can you run both programs in one visit?
Yes. We coordinate DOT-regulated and Non-DOT collections in a single visit — different forms, different lab routing paths, one dispatch. DOT and Non-DOT groups must be clearly separated in the order.
