Steps
Check whether the material hauled (domestic septage/sewage) is classified as a DOT hazardous material under 49 CFR - it generally is not
Note that FMCSA's Cargo Tank Facility Registration program (49 CFR 107 Subpart F, filed via the MOTUS system) targets cargo tank manufacturers, repairers, and testers of DOT-specification (hazmat) tanks, not businesses simply operating a vacuum tank for non-hazmat liquid waste
Confirm the truck's separate FMCSA obligations instead: USDOT number registration, driver qualification (Part 391), vehicle inspection/maintenance (Part 396), and hours of service, which apply based on vehicle weight/interstate operation regardless of hazmat status
If the vehicle is ever also used to haul an actual hazmat commodity, re-check whether cargo tank specification/registration and CDL hazmat endorsement rules apply to that use
Check state-level commercial vehicle/tank inspection requirements too, since these can apply to septage haulers independent of any FMCSA hazmat program
Known gotchas
Don't assume "vacuum truck = hazmat cargo tank facility registration required" - that federal program targets tank manufacture/testing/repair entities, not routine non-hazmat hauling operations
USDOT number and basic safety regulation (driver, vehicle, hours-of-service) obligations can still apply even when hazmat-specific rules don't - these are separate FMCSA tracks
State septage-hauler vehicle rules (leak-proof/fly-tight container requirements, per-vehicle licensing, state agency vehicle inspections) are a distinct, usually more directly applicable, compliance layer than federal hazmat cargo tank rules
