On-Site Employer Drug Testing in Butte, Montana
Montana Resources Continental Mine - MSHA Part 100 Compliance - Berkeley Pit Superfund Contractors - BNSF Silver Bow Junction - I-15/I-90 Interchange - Silver Bow County Construction
Butte-Silver Bow is Montana's mining heritage city and still an active extraction economy. Montana Resources operates the Continental Mine -- one of the largest open-pit copper mines in North America -- where MSHA 30 CFR Part 100 regulations govern mine operator safety obligations and support robust drug and alcohol testing programs for miners and contractors. The Berkeley Pit Superfund site generates ongoing environmental remediation contractor activity governed by EPA requirements and OSHA standards that support drug testing as a worksite safety condition. The I-15/I-90 interchange in Butte is a major commercial trucking nexus, with FMCSA CDL testing obligations for motor carriers. BNSF's Silver Bow Junction serves the mine and regional freight. Our collectors reach mine portals, Superfund contractor staging areas, and trucking operations directly.
OnSite Employer Testing coordinates mobile drug testing collections at your Butte-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.

MSHA Drug Testing and Montana Employer Rights in Butte
While MSHA 30 CFR Part 100 does not mandate a specific drug testing program the way DOT Part 40 does, mine operators and contractors are expected to implement and enforce drug and alcohol policies as part of their required safety programs under the Mine Act. A positive result for a miner in a safety-critical role at the Continental Mine or a Berkeley Pit remediation contractor creates serious liability exposure if no testing program existed. OSHA's general duty clause further supports testing for safety-sensitive contractor roles on Superfund sites. Montana Code Ann. Section 16-12-108 protects Silver Bow County employers' rights to test and take adverse action regardless of cannabis legalization.

Questions from employers in this region
Does MSHA require drug testing for miners at the Continental Mine?
MSHA 30 CFR Part 100 does not prescribe a mandatory drug testing program identical to DOT Part 40, but mine operators are required to maintain safety programs under the Federal Mine Safety and Health Act, and drug and alcohol policies are a recognized component. More practically, a mine operator or contractor that fails to test and then suffers a drug-related accident faces significant MSHA citation exposure and civil liability. We provide on-site collection at the Continental Mine contractor staging area or portal to keep your program current and documented.
We are a Superfund remediation contractor at Berkeley Pit. Should we have a drug testing program?
Yes, strongly recommended. EPA contractor requirements for Superfund sites typically include OSHA compliance and hazardous materials handling protocols that are reinforced by drug and alcohol testing programs. OSHA's general duty clause can be cited for failure to maintain a safe workplace if drug impairment contributes to an incident at a hazardous site. We provide on-site collections so your remediation crew stays on the Butte worksite -- no lost production time for clinic trips.
Our Butte trucking company uses the I-15/I-90 interchange. What FMCSA testing do we need?
CDL drivers in interstate commerce require a complete DOT FMCSA program: pre-employment, random (50% drug/10% alcohol annually), post-accident, reasonable suspicion, and return-to-duty testing under 49 CFR Part 40. We collect on-site at your Silver Bow County terminal or dispatch yard and provide full chain-of-custody documentation and MRO coordination.
