Questions from employers in this region
Can you collect at defense contractor facilities with secure perimeters like NASSCO?
We coordinate with your facility security and EH&S team to arrange collector access under your site's badging and escort protocols. All collections meet DOD contractor drug-free workplace requirements and 49 CFR Part 40 chain-of-custody standards.
We operate drayage trucks through Otay Mesa. Do you test near the crossing?
Yes. We provide on-site FMCSA Part 382 collections at drayage yards and staging areas near the Otay Mesa Port of Entry — keeping CDL drivers in compliance without long clinic detours from the crossing.
Does California AB 2188 affect drug testing for defense contractor employees in San Diego?
Federal DOD contractor drug-free workplace requirements and federal DOT regulations preempt California AB 2188 for safety-sensitive and federally-contracted positions. Defense contractor employees in covered roles remain subject to full drug testing panels.
