North Little Rock sits across the Arkansas River from Little Rock, connected by I-40 and I-30 bridges that carry some of the highest freight volumes in the mid-South. Union Pacific's North Little Rock rail yard is a major classification and crew change facility, making it one of the most FRA-regulated employer sites in Arkansas. The Port of Little Rock on the Arkansas River handles barge traffic connecting the city to the McClellan-Kerr Arkansas River Navigation System and the Gulf of Mexico, generating USCG-regulated employer exposure. The I-30 and I-40 interchange in North Little Rock attracts warehousing, distribution, and logistics employers seeking central Arkansas positioning. Arkansas Children's Hospital and Baptist Health's North Little Rock facilities add significant healthcare employer demand. OnSite Employer Testing dispatches mobile collectors to North Little Rock rail facilities, port operations, warehouse docks, and employer sites throughout the Pulaski County north bank corridor.

North Little Rock is the industrial and rail operations counterpart to the state capital - the freight yard, warehouse district, and Arkansas River port city that keeps the Little Rock metro's supply chain moving and generates some of the most consistent DOT and rail testing demand in the state.

Applicable Regulations - North Little Rock, AR
North Little Rock's employer base spans multiple modal regulations. Union Pacific rail employees in covered service follow 49 CFR Part 219 (FRA).

Questions from employers in this region
We are a Union Pacific contractor at the North Little Rock rail yard performing track maintenance - what FRA testing applies to our employees?
If your employees perform covered service under 49 CFR Part 219 - including working on or near live track, operating on-track equipment, or certain maintenance functions - FRA drug and alcohol testing requirements apply. FRA rules differ from FMCSA including mandatory blood collection in certain qualifying accident scenarios and specific on-duty BAC thresholds. We perform on-site collections for FRA-covered programs at your North Little Rock rail facility.
We operate barge tows at the Port of Little Rock on the Arkansas River - what testing applies to our crew?
USCG regulations under 46 CFR Part 16 apply to crewmembers on inspected commercial vessels and certain uninspected commercial towing vessels. Consult your USCG marine inspector on your specific vessel classification and crew coverage. We perform on-site collections for USCG-covered programs at your North Little Rock port facility.
We run a warehouse operation on I-30 in North Little Rock with both CDL drivers and dock workers - can you handle both programs in one dispatch?
Yes. Specify at booking which employees are FMCSA-regulated CDL drivers and which are non-DOT dock staff. Our collector arrives with correct documentation for each program. Provide your dock schedule and shift windows so we can minimize operational disruption.
