DOT-COMPLIANT · ON-SITE EMPLOYER DRUG TESTING
Mobile Employer Drug Testing in Longview, Texas
We travel to your fleet yard, rail facility, chemical plant, or energy job site and administer federally compliant DOT and Non-DOT collections on-site. No clinic. No downtime.
Longview anchors the East Texas industrial corridor at the intersection of I-20 and U.S. 259, serving as the region's primary freight, rail, and energy employer hub. Union Pacific and BNSF both operate freight rail facilities in the Longview area, making it one of the few East Texas cities with dual Class I rail service under FRA jurisdiction. Eastman Chemical Company's Longview Operations — one of the largest integrated chemical manufacturing sites in the United States by square footage — employs thousands of workers and contractors at a PHMSA-regulated chemical and polymer manufacturing complex. LyondellBasell, Formulyx, and other chemical manufacturers operate facilities in the broader Longview area. The Gregg County industrial base also includes FMCSA-regulated oilfield service carriers, pipe and supply distribution companies, and intermodal logistics operators. East Texas Regional Airport supports charter and corporate aviation. For employers in a city where chemical manufacturing, dual Class I rail, and oilfield logistics intersect, mobile testing is the operational standard that keeps safety-sensitive workforces compliant without disrupting continuous-process operations.
OnSite Employer Testing coordinates mobile drug testing collections at your Longview chemical facility, rail yard, or fleet terminal. We do not operate a clinic. Review how it works or browse all locations we serve.
Why Longview Employers Need Mobile Testing
Eastman Chemical Longview is a continuous-process manufacturing complex operating around the clock with PHMSA-regulated pipeline and chemical plant employees who cannot be pulled from process control positions for clinic trips. The site's size and continuous operation make mobile collection at the facility — timed to shift changes and scheduled windows — the only model that serves a chemical plant workforce without creating safety gaps in process areas.
Longview's dual Class I rail infrastructure — Union Pacific and BNSF — creates FRA post-accident testing obligations that require immediate response capability. A post-accident event at a Longview rail yard at 0200 cannot wait for a clinic to open at 0800. Mobile collection at the rail facility, available on short notice, is the FRA-compliant response model for a 24-hour rail operation.
Program design and compliance obligations remain your responsibility under applicable law — we coordinate the collections.
Industries We Serve in Longview
Chemical and Polymer Manufacturing — Eastman
Eastman Chemical Company's Longview Operations is one of the largest integrated chemical manufacturing sites in the United States, producing cellulose-based specialty materials, plastics, and chemicals across a massive campus with its own internal pipeline and utility systems. PHMSA 49 CFR Part 199 covers pipeline and chemical plant employees at facilities of this type. Turnaround contractors working at the Eastman campus require Non-DOT pre-access testing as a condition of site entry. We coordinate PHMSA-compliant energy and utilities collections and Non-DOT pre-access testing at chemical manufacturing facilities throughout the Longview area.
Rail — Union Pacific and BNSF
Union Pacific and BNSF both provide freight rail service to the Longview industrial corridor, making Longview one of East Texas's most rail-connected markets. FRA 49 CFR Part 219 requires covered railroad employees at both carriers' Longview operations to participate in random, post-accident, and reasonable suspicion programs. We coordinate FRA-compliant DOT drug testing collections at rail facilities and crew reporting points in Gregg County.
Oilfield Supply and Distribution
The East Texas oilfield — the Longview area sits within the historic East Texas Oil Field region — supports pipe and supply distribution companies, oilfield service carriers, and energy equipment logistics operators running FMCSA-regulated fleets. CDL drivers hauling tubular goods, oilfield chemicals, and production equipment throughout East Texas require pre-employment and random testing programs. We coordinate logistics and transportation collections at pipe yard dispatch areas and carrier terminals in Gregg County.
Construction and Industrial Contractors
Longview's chemical and industrial manufacturing base generates active construction project demand for turnaround maintenance, capital expansion, and infrastructure work at Eastman and other facilities. General contractors and craft trade employers maintain Non-DOT pre-access programs required by industrial host employers. CDL crane and heavy equipment operators require FMCSA programs. We coordinate both program types at contractor yards and staging areas throughout Gregg County.
Warehousing and Cross-Dock Logistics
Longview's I-20 position and dual Class I rail access make it an East Texas warehousing and distribution point for regional industrial and consumer supply chains. Warehousing and distribution employers in the Gregg County industrial park network require CDL driver testing programs. We coordinate collections at distribution facilities and cross-dock operations throughout the Longview area.

Questions from employers in this region
Eastman Chemical Longview has turnaround contractor crews that vary from 50 to 500 workers depending on outage scope. How do you handle variable-volume pre-access testing?
We scale mobile collection visits to match your mobilization schedule. For small crews, a single visit handles the collection. For large-scale turnaround mobilizations, we coordinate multiple collection windows across the mobilization days. Contact us at (219) 315-0345 to discuss volume and timing for your planned outage.
Longview has both Union Pacific and BNSF rail operations. If a post-accident event involves a UP crew at a crossing where BNSF track is also present, which railroad's FRA program applies?
FRA post-accident testing obligations apply to the covered employees of the railroad whose equipment was involved in the accident and who were performing covered service at the time. If both carriers' employees were involved, each carrier is responsible for testing its own covered employees under its own FRA program. Program design and compliance obligations remain your responsibility — we coordinate the collections for the covered employees you direct us to test.
Do you serve East Texas oilfield chemical carriers hauling from Longview-area supply depots to well sites in Panola and Rusk Counties?
Yes. FMCSA-regulated chemical carriers operating from Longview and surrounding counties in East Texas are within our service range. We coordinate pre-employment and random collections at carrier yards and chemical supply facilities in Gregg County.
Can you serve LyondellBasell or Formulyx facilities in the Longview area alongside the Eastman campus?
Yes. We coordinate collections for multiple industrial employer clients in the same area in separate visits or in scheduled corridor visits when logistics allow. Each employer's collection is managed under their own program with their designated employer representative.
