Potential Spill (gallons)
550
Required Containment (gallons)
60.5
Spill Weight (lbs)4,587
Total Inventory (gallons)550
Total w/ Precipitation (gallons)66.6
Dike Area Needed (sq ft)17.8
Absorbent Needed (lbs)550
How to Use This Calculator
- Enter the Container Volume (gallons) and Number of Containers for your storage area inventory.
- Set the Spill Scenario (%) — typically 100% for a single catastrophic release or lower for a partial breach scenario.
- Enter the Specific Gravity of the material (water = 1.0) to calculate the spill weight in pounds.
- Review Potential Spill (gallons) and Spill Weight (lbs) to size response resources including absorbents.
- Check Required Containment (gallons) to confirm your secondary containment system is adequately sized per EPA SPCC.
- Use Absorbent Needed (lbs) to stock the appropriate emergency response supplies at the storage location.
How the result changes with Container Volume (gallons)
| Container Volume (gallons) | Potential Spill (gallons) | Required Containment (gallons) |
|---|---|---|
| 10,001 | 100,010 | 11,001.1 |
| 35,001 | 350,010 | 38,501.1 |
| 65,000 | 650,000 | 71,500 |
| 90,000 | 900,000 | 99,000 |
What each input means
- Container Volume (gallons)
- Volume of each container (e.g., 55 for a drum).
- Number of Containers
- Total containers in the storage area.
- Spill Scenario (%)
- Percentage of largest container that could spill.
- Specific Gravity
- Specific gravity of the material (water = 1.0).
