SPCC Thresholds — IBC Tote Reference

The EPA's Spill Prevention, Control, and Countermeasure rule (40 CFR Part 112) applies to facilities with aboveground oil storage above 1,320 gallons — or any single container over 660 gallons — where there is a reasonable expectation of discharge reaching navigable waters. All aboveground containers count toward the total, not just IBC totes.

Secondary Containment: The 110% Rule

Every aboveground oil container subject to SPCC must have secondary containment sized for 110% of the largest single container's volume. For a 275-gallon IBC tote, that means at least 303 gallons of containment. For a 330-gallon tote, at least 363 gallons. Most purpose-built IBC spill pallets are rated at 360–400 gallons and comply for single-tote use.

Some states require containment of 110% of the total group volume, not just the largest container. Check your state environmental agency's requirements in addition to federal SPCC rules.
