DOT-COMPLIANT · ON-SITE EMPLOYER DRUG TESTING
On-Site Employer Drug Testing in Great Falls, Montana
Malmstrom Air Force Base - BNSF Hi-Line Division - Great Falls International Airport - Cascade County Construction - I-15 Corridor Carriers - Agricultural Services
Great Falls is home to Malmstrom Air Force Base, the Air Force Global Strike Command installation responsible for over 150 Minuteman III ICBM launch facilities across central Montana. Defense contractors and subcontractors performing work on or near Malmstrom must comply with DoD contractor drug testing requirements under 10 U.S.C. Section 2701 and Executive Order 12564, which mandate testing for safety-sensitive and security-clearance positions. BNSF's Hi-Line rail corridor runs through Cascade County, triggering FRA 49 CFR Part 219 obligations for maintenance-of-way and operations crews. Great Falls International Airport handles both military and commercial traffic, with FAA 14 CFR Part 120 covering ground safety-sensitive personnel. The I-15 corridor through Cascade County is a primary north-south commercial trucking route connecting Canada to Salt Lake City. Our collectors reach Malmstrom contractor staging areas, rail facilities, trucking terminals, and construction sites directly.
OnSite Employer Testing coordinates mobile drug testing collections at your Great Falls-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.

DoD Contractor Testing and Montana Employer Rights in Great Falls
Defense contractors at Malmstrom AFB face one of the most demanding drug testing frameworks outside of nuclear power -- Executive Order 12564 (Drug-Free Federal Workplace) and DoD Instruction 1010.09 require testing of employees with access to classified information, sensitive military equipment, or nuclear weapons systems. A THC-positive result for a Malmstrom contractor can trigger immediate revocation of base access and security clearance regardless of Montana's recreational cannabis law. Montana Code Ann. Section 16-12-108 protects employer rights statewide, but for Malmstrom contractors, federal preemption makes that point moot -- federal contractor obligations are absolute. Non-defense employers in Cascade County retain full discretion under state law to maintain zero-tolerance policies covering all controlled substances including cannabis.

Questions from employers in this region
Our company has a contract at Malmstrom AFB. Do we need a separate drug testing program from our civilian commercial program?
Yes, in most cases. DoD contracts for work involving classified access, security-clearance positions, or safety-sensitive roles at military installations require a drug testing program that complies with Executive Order 12564, DoD Instruction 1010.09, and any additional requirements in your specific contract. This is separate from and more stringent than a standard non-DOT commercial program. We provide on-site collections for contractor personnel at Malmstrom staging areas and can document results for contract compliance purposes. Consult your contracting officer for the specific testing requirements in your statement of work.
We are a grain elevator operator in Cascade County with CDL drivers. What DOT testing does that require?
CDL drivers operating commercial motor vehicles in interstate commerce are covered by DOT FMCSA 49 CFR Part 40 regardless of industry. Grain elevator employers must maintain a written drug and alcohol testing program, conduct pre-employment, random (50% annual drug, 10% annual alcohol), post-accident, reasonable suspicion, and return-to-duty testing for all CDL-covered drivers. We come to your Cascade County facility and collect on-site so drivers do not lose field time traveling to a clinic.
Can we test Great Falls employees for cannabis under Montana's recreational marijuana law?
Yes. Montana Code Ann. Section 16-12-108 preserves employer rights to maintain drug-free workplace policies and test for cannabis. A positive THC result is fully actionable under a properly written policy -- you may decline to hire, suspend, or terminate based on a confirmed positive regardless of off-duty recreational use. We recommend ensuring your policy is in writing and communicated to employees before testing begins.
