DOT-COMPLIANT · ON-SITE EMPLOYER DRUG TESTING
Mobile Employer Drug Testing in Beaumont, Texas
We travel to your refinery, petrochemical facility, port terminal, or fleet yard and administer federally compliant DOT and Non-DOT collections on-site. No clinic. No downtime.
Beaumont anchors the Golden Triangle — the Texas petrochemical corridor connecting Beaumont, Port Arthur, and Orange — one of the most refinery-dense regions in the United States. ExxonMobil's Beaumont Refinery is one of the largest crude processing facilities in the country, with a nameplate capacity exceeding 360,000 barrels per day. Total Energies and DuPont operate major chemical manufacturing facilities in the region. The Port of Beaumont is a U.S. Army installation logistics port — the busiest military port in the United States — handling military vehicles, equipment, and supplies under FMCSA, FRA, and federal contractor oversight. Union Pacific and Kansas City Southern (now CPKC) both provide freight rail service to the Beaumont industrial complex under FRA jurisdiction. The concentration of PHMSA-regulated pipeline operators, refinery terminal workers, and FMCSA-regulated carriers in Beaumont creates a multi-modal DOT testing demand that no single clinic can efficiently serve.
OnSite Employer Testing coordinates mobile drug testing collections at your Beaumont refinery, port terminal, or industrial facility. We do not operate a clinic. Review how it works or browse all locations we serve.
Why Beaumont Employers Need Mobile Testing
Beaumont's refinery operations run without interruption. ExxonMobil's Beaumont Refinery, one of the largest in the U.S., operates process units that cannot be left unattended while safety-sensitive employees take clinic trips. PHMSA 49 CFR Part 199 covered employees — pipeline technicians, loading rack operators, and gas plant workers — are precisely the workforce that cannot leave a continuous-process environment for a testing appointment. Mobile collection at the refinery facility removes that conflict entirely.
The Port of Beaumont's military logistics role creates a federal contractor testing dimension that is entirely absent from competing testing pages. Contractors loading military vehicles and equipment at Military Ocean Terminal Beaumont (MOTB) maintain drug-free workplace programs under federal contract requirements alongside FMCSA DOT programs for their CDL-operating stevedores and transport drivers. Mobile testing at the MOTB contractor facility eliminates clinic routing for a workforce that often works under tight ship loading schedules.
Program design and compliance obligations remain your responsibility under applicable law — we coordinate the collections.
Industries We Serve in Beaumont
Refining and Petrochemical
ExxonMobil's Beaumont Refinery and Chemical Plant is one of the largest integrated refining and petrochemical operations in the United States. Total Energies Petrochemicals and DuPont operate significant chemical manufacturing facilities in the Beaumont area. Pipeline technicians, terminal operators, and plant logistics employees at these PHMSA-regulated facilities are covered under 49 CFR Part 199. Turnaround contractors — the rotating craft workforce that maintains refinery equipment — require Non-DOT pre-access testing as a condition of site entry at most Beaumont refinery locations. We coordinate PHMSA-compliant energy and utilities collections and Non-DOT pre-access testing at refinery gates and contractor staging areas throughout the Golden Triangle.
Military Ocean Terminal Beaumont — Port and Federal Logistics
Military Ocean Terminal Beaumont (MOTB) is operated by the U.S. Army and is the busiest military seaport in the United States, activated during major deployments to pre-position equipment for overseas operations. Stevedoring contractors, freight handlers, and CDL-operating logistics contractors working at MOTB are subject to both FMCSA 49 CFR Part 382 (for CDL operators) and Non-DOT drug-free workplace requirements under their federal contracts. We coordinate both DOT drug testing and Non-DOT workplace drug testing for MOTB contractors at their Beaumont facilities.
Rail — Union Pacific and CPKC
Union Pacific and CPKC (formerly Kansas City Southern) both provide freight rail service to Beaumont's refinery and port complex. FRA 49 CFR Part 219 requires covered railroad employees at both carriers' Beaumont operations to participate in random, post-accident, and reasonable suspicion programs. We coordinate FRA-compliant collections at rail yards and crew reporting facilities in Jefferson County.
Trucking and Petrochemical Carrier Fleets
FMCSA-regulated tanker and flatbed carriers hauling petroleum products, chemicals, and industrial materials from Beaumont refineries and chemical plants operate out of terminals throughout Jefferson County. Hazardous materials endorsement requirements and FMCSA Part 382 testing obligations apply to CDL drivers transporting hazardous commodities from these facilities. We coordinate logistics and transportation collections at carrier terminals and fleet yards throughout the Beaumont area.
Construction and Turnaround Workforce
Beaumont's refinery and industrial construction sector employs thousands of craft workers on capital projects and scheduled turnarounds at ExxonMobil and other facilities. Construction contractors working in the Golden Triangle maintain Non-DOT pre-access programs required by refinery host employers, often with short mobilization windows that make clinic routing logistically impossible. We coordinate pre-access and random Non-DOT testing at contractor yards and staging areas throughout Jefferson County.

Questions from employers in this region
ExxonMobil Beaumont runs multiple contractor crews during a turnaround. Can you coordinate same-day testing for 50 or more workers at the contractor staging area?
Yes. High-volume pre-access collections for refinery turnaround mobilizations — 50 or more donors in a single day — are a standard use case. We coordinate collections at the contractor staging area or gate facility with a collection schedule that matches your workforce report time. Contact us at (219) 315-0345 to discuss volume and logistics.
Military Ocean Terminal Beaumont contractors load equipment under tight ship departure schedules. Can you coordinate pre-employment testing at the MOTB contractor facility before a loading contract begins?
Yes. We coordinate pre-employment and pre-access collections at contractor facilities in the Beaumont port area. Testing at the contractor's facility — not a clinic across town — ensures workers are cleared and available before the ship loading window opens.
We haul hazmat from Beaumont refineries. Does the hazardous materials CDL endorsement change the drug testing requirements?
The hazardous materials endorsement requires a TSA security threat assessment and adds regulatory requirements for the endorsement itself, but it does not create a separate or more stringent drug testing program. CDL drivers hauling hazmat in a CMV in interstate commerce are subject to standard FMCSA 49 CFR Part 382 requirements. The HM endorsement renewal process includes a TSA background check that is separate from DOT drug testing. Program design and compliance obligations remain your responsibility — we coordinate the collections.
Do you serve petrochemical employers in Port Arthur and Orange as well as Beaumont?
Yes. Port Arthur and Orange are within our standard Golden Triangle service range. Employers at Total Energies Port Arthur Refinery, the Motiva Port Arthur Refinery, and industrial facilities throughout Jefferson and Orange Counties can be served in the same mobile visit as Beaumont employers when logistics allow.
