Questions from employers in this region
Pennsylvania state agencies contract with hundreds of vendors in Harrisburg — do those contractors need drug testing?
Pennsylvania state contractors are subject to the Pennsylvania Drug and Alcohol Abuse Control Act and applicable federal requirements for any federally-funded contracts. CDL-operating contractor employees are subject to FMCSA Part 382 regardless of state agency work. We coordinate both DOT-regulated CDL testing and Non-DOT company-policy collections for state agency contractor employers.
PENNDOT projects are everywhere in Central PA — can you reach active I-81 and I-76 construction sites?
Yes. We come to your active PENNDOT project site trailer or staging area anywhere along I-81, I-76, I-83, or US-15 in Central Pennsylvania, conducting on-site CDL and equipment operator collections without pulling workers off the project.
UGI and PPL both operate gas distribution in the Harrisburg area — can you serve both utilities' contractor programs?
Yes. We maintain separate PHMSA Part 199 compliant programs for UGI Utilities and PPL Gas contractor employers, with distinct chain-of-custody records for each utility's covered-function pipeline workforce throughout South-Central Pennsylvania.
