Stillwater is the home of Oklahoma State University and the county seat of Payne County, positioned in the geographic heart of the SCOOP (South Central Oklahoma Oil Province) and STACK (Sooner Trend Anadarko Basin Canadian Kingfisher) oil plays that have driven significant oilfield activity in the surrounding region. Oilfield service companies, drilling supply firms, and water haulers use Stillwater as a staging and supply base for nearby field operations. US-177 runs north to Ponca City and south toward Shawnee, while SH-51 connects Stillwater west to I-35 and east toward Tulsa. Agriculture and grain processing remains significant in Payne County, and OSU's research and facilities contractor workforce adds non-DOT employer testing demand. Stillwater's construction sector has grown with university expansion and residential development. OnSite Employer Testing dispatches mobile collectors to Stillwater oilfield staging areas, grain facilities, fleet yards, and employer sites throughout Payne County.

Questions from employers in this region
We haul produced water for SCOOP/STACK oil operations out of Stillwater with CDL tanker drivers - what testing applies?
CDL tanker drivers operating qualifying CMVs are subject to FMCSA 49 CFR Part 382. Water haulers and oilfield support truckers are among the most common users of DOT mobile testing services in the Oklahoma play areas. We dispatch to your Stillwater yard or oilfield staging area for random, pre-employment, and post-accident collections.
We operate pipeline gathering systems for SCOOP production in Payne County - does PHMSA testing apply to us?
PHMSA testing under 49 CFR Part 199 applies to operators of regulated pipeline facilities. Gathering line classification depends on the line's operating pressure, location, and commodity transported. Some gathering lines are regulated under 49 CFR Part 192 or Part 195; others may be exempt. Consult your PHMSA compliance officer on whether your specific gathering system triggers Part 199 testing obligations.
Our oilfield service company has employees who use Oklahoma OMMA cards - how do we handle positive THC results?
Under 63 O.S. Section 425, Oklahoma employers may enforce drug-free workplace policies and act on positive cannabis results regardless of OMMA card status. Most oil and gas operators also require their contractors to enforce drug-free policies as a condition of field access. For DOT-regulated drivers, there is no OMMA exception under federal law. Policy enforcement decisions are the employer's responsibility.
