Gillette, WY Mobile Drug & Alcohol Testing
Powder River Basin coal mining employers · MSHA surface mine workforce · I-90 freight corridor fleet operators · Natural gas and energy service companies · Same-day dispatch available
Gillette anchors Campbell County in northeastern Wyoming, the heart of the Powder River Basin coal formation that produces more coal than any other region in the United States. Major surface mine operators including Peabody Energy, Arch Resources, and NACCO Industries run massive dragline and shovel operations employing thousands of miners and contractors subject to MSHA safety standards. While MSHA does not federally mandate drug testing for surface mining operations, virtually every Powder River Basin coal operator maintains a rigorous drug-free workplace program as a condition of insurance, contractor qualification, and operational safety management. Natural gas production in Campbell County adds PHMSA pipeline testing exposure. I-90 motor carriers hauling coal, oversize loads, and energy equipment freight through Campbell County represent consistent FMCSA testing demand. Campbell County Memorial Hospital anchors healthcare employer demand. OnSite Employer Testing dispatches mobile collectors to Gillette mine contractor facilities, fleet yards, energy staging areas, and employer sites throughout Campbell County when routing and collector availability allow.
OnSite Employer Testing coordinates mobile drug testing collections at your Gillette-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.
Gillette is the coal capital of the United States - the Powder River Basin's largest coal-producing county seat where surface mine operators, MSHA-regulated employers, and energy service companies generate one of the most safety-driven testing markets in the Mountain West.

Applicable Regulations - Gillette, WY
MSHA regulates surface coal mine safety in Campbell County under 30 CFR Parts 46 and 48 (training) but does not federally mandate drug testing for mining employees. However, virtually all Powder River Basin coal operators maintain drug-free workplace programs that exceed standard non-DOT employer programs, driven by insurance requirements, corporate safety management systems, and operator contractor pre-qualification standards. Natural gas pipeline operators in Campbell County follow 49 CFR Part 199 (PHMSA). Motor carriers on I-90 follow 49 CFR Part 382 (FMCSA) and 49 CFR Part 40. Wyoming has no cannabis law - no state-level accommodation obligations exist for Gillette employers. Program design remains the employer's responsibility.

Questions from employers in this region
We operate a surface coal mine in Campbell County - MSHA does not require drug testing, so what drives our obligation to test?
While MSHA does not federally mandate drug testing for surface mines, Powder River Basin coal operators maintain drug-free workplace programs for several compelling reasons: workers' compensation insurance carrier requirements, mine operator contractor qualification standards (Peabody, Arch, and similar operators require contractors to maintain programs as a condition of site access), corporate safety management systems, and the significant MSHA citation risk when a post-accident investigation reveals impairment and no program was in place. We dispatch to your Campbell County mine facility for any employer-designed program.
We haul oversize mining equipment on I-90 through Gillette with permit loads - what DOT testing applies to our drivers?
CDL drivers operating qualifying CMVs are subject to FMCSA 49 CFR Part 382 regardless of whether the load requires an oversized permit. Permit load status does not create additional DOT testing requirements beyond standard FMCSA obligations. We dispatch to your Gillette terminal or staging area for pre-employment, random, and post-accident collections.
Wyoming has no cannabis law - how does that simplify management of our mining contractor workforce drug policy?
Significantly. No medical card defense, no recreational-use employment protection, no state accommodation requirement. Your written zero-tolerance policy can be enforced immediately and consistently. For safety-intensive surface mining environments where impairment exposure is acute, the combination of Wyoming law and operator-required programs creates a clean enforcement environment. Policy decisions are the employer's responsibility.
