Storing IBC totes at a commercial facility in Missouri involves regulatory considerations that vary based on what's inside them, how many you have, and where they're located. Here's a practical overview of the regulations that most commonly apply to IBC storage in the St. Louis area.
EPA/SPCC Regulations (Spill Prevention)
If your facility stores more than 1,320 gallons of oil or petroleum products in aboveground containers (that's roughly 5 full IBCs), you may be subject to SPCC (Spill Prevention, Control, and Countermeasure) planning requirements under 40 CFR 112.
Key requirements: - Written SPCC plan certified by a Professional Engineer - Secondary containment (containment pallets or bermed areas) capable of holding 110% of the largest container's volume - Regular inspections documented in writing - Employee training on spill response
Does this apply to you? If you're storing water, food products, or non-petroleum materials, SPCC likely doesn't apply. But if you have oils, fuels, lubricants, or petroleum-based chemicals in IBCs, count your total volume.
Fire Code (IFC/NFPA)
The International Fire Code and NFPA standards regulate storage of flammable and combustible liquids:
IBC-specific provisions: - Maximum storage height for flammable liquids in IBCs: typically 2 levels - Aisle spacing between IBC storage rows: minimum 4 feet - Fire protection (sprinklers) requirements depend on quantity and material class - Outdoor storage setbacks from buildings: minimum 20 feet for flammable liquids
Indoor storage limits vary by building classification: - Control areas in non-sprinklered buildings: limited to specific maximum aggregate volumes - Sprinklered buildings: higher limits with proper rack protection
Contact your local fire marshal's office for specific limits applicable to your facility.
Missouri DNR (Department of Natural Resources)
The Missouri DNR regulates: - Hazardous waste storage (if your IBC contents qualify as hazardous waste under RCRA) - Wastewater discharge (if cleaning IBCs generates wastewater) - Air quality (if IBC contents are volatile and venting occurs)
Practical note: Most IBC users handling common commercial products (soaps, foods, agricultural products) won't trigger DNR involvement. Facilities handling listed hazardous chemicals should consult directly with DNR for specific requirements.
Secondary Containment Requirements
Regardless of specific regulations, secondary containment is strongly recommended for any IBC holding materials other than clean water:
Options: - Purpose-built IBC containment pallets (110% capacity) - Concrete-bermed containment areas - Double-wall secondary containment systems - Portable containment berms for temporary storage
Best Practices for Compliant Storage
1. Label everything. Each IBC should display contents, hazard information, and date of receipt. 2. Segregate incompatible materials. Don't store acids next to bases, or oxidizers next to flammables. 3. Maintain aisle access. Emergency responders and your own workers need clear pathways. 4. Document inspections. Weekly visual checks of all IBCs with written records. 5. Have spill materials available. Absorbent pads, booms, or granular absorbent near IBC storage. 6. Train employees. Everyone who works near IBCs should know spill response basics.
