On-Site Employer Drug Testing in Glendive, Montana
Bakken Formation Eastern Montana Extension - BNSF Yellowstone Subdivision - US-16/I-94 Williston Corridor - Dawson County Oilfield Services - Sidney/Richland County Spillover - Eastern Montana Agriculture
Glendive sits at the center of Montana's Bakken oil country, where Dawson County and neighboring Richland and Roosevelt counties share the eastern extension of the Williston Basin formation that drives North Dakota's oil patch economy. Pipeline operators, oilfield services contractors, and crude-by-rail operators in the Glendive area face PHMSA 49 CFR Parts 199 and 382 testing obligations for hazardous liquid pipeline personnel and hazmat transportation employees. BNSF's Yellowstone Subdivision carries substantial crude-by-rail traffic through Glendive, with FRA 49 CFR Part 219 obligations for train and engine crews and maintenance-of-way workers. The I-94/US-16 corridor connects Glendive to both the Williston Basin hub and the Billings refinery complex, with FMCSA CDL testing required for commercial freight and tanker operators. Our collectors reach remote oilfield contractor sites, rail facilities, and agricultural operations in Dawson County without requiring workers to travel to Billings or Williston.
OnSite Employer Testing coordinates mobile drug testing collections at your Glendive-area facility, yard, terminal, or job site. We do not operate a clinic. Review how it works, browse Montana locations, or see all locations we serve.

Bakken PHMSA and Eastern Montana Cannabis Law
Eastern Montana oilfield operators and pipeline companies face PHMSA 49 CFR Part 199 (gas/hazardous liquid pipelines) and Part 382 (commercial motor vehicle operators) obligations. Montana Code Ann. Section 16-12-108 gives Dawson County employers full authority to test for cannabis and enforce zero-tolerance policies. In the Bakken context, where oilfield safety incidents carry significant federal scrutiny, a documented drug and alcohol testing program is a practical necessity beyond regulatory compliance.

Questions from employers in this region
We are a small oilfield services contractor in Dawson County. Do we need a drug testing program?
If any of your employees operate commercial motor vehicles (CDL), you need a FMCSA-compliant drug and alcohol program. If any perform pipeline operations under PHMSA jurisdiction, Part 199 applies. Beyond regulatory mandates, oilfield services contractors working for major operators are increasingly required by contract to maintain testing programs as a condition of site access. We provide flexible on-site programs sized for small contractors -- call (219) 315-0345 for a quote.
Can you reach remote Dawson County oilfield sites for collections?
Yes. We dispatch collectors to remote eastern Montana oilfield sites. For pre-employment and routine random collections, we coordinate a visit schedule. For post-accident and reasonable suspicion, call (219) 315-0345 immediately and we will mobilize. DOT post-accident alcohol testing windows are time-critical -- do not wait.
How does cannabis testing work for Glendive oilfield employers?
Montana Code Ann. Section 16-12-108 allows you to include cannabis in your testing panel and take adverse action on positive results under a written drug-free workplace policy. Standard 5-panel and 10-panel screens include THC metabolites. For federally regulated pipeline and trucking roles, DOT Part 40 governs and cannabis is tested regardless of state law.
