Questions from employers in this region
Mosaic handles ammonia and sulfuric acid pipelines — do PHMSA requirements differ for hazmat pipelines?
49 CFR Part 199 PHMSA requirements apply to operators of hazardous liquid and gas pipelines broadly — including Mosaic's ammonia and sulfuric acid pipeline systems at Riverview. Covered function employees operating or maintaining these systems are subject to the same PHMSA anti-drug and alcohol misuse prevention program requirements as natural gas pipeline operators.
Can you coordinate MacDill AFB defense contractor testing with base security restrictions?
Yes. We work with your MacDill contractor program manager and facility security officer to arrange collector credentialing and access under base protocols. All collections meet DOD contractor drug-free workplace requirements.
Does the Florida Drug-Free Workplace Act require a different testing panel than federal DOT?
The Florida Drug-Free Workplace Act specifies testing requirements under Florida law. For DOT-regulated employees, federal 49 CFR Part 40 standards govern and exceed Florida state requirements. For non-DOT employees you want to cover under the Florida DFWP premium discount, we collect using procedures that satisfy the state program requirements.
