SPCC plans require you to know the exact capacity of every oil storage container on site. If your facility stores more than 1,320 gallons of oil in aboveground containers, you need a written SPCC plan. This calculator handles the math for horizontal cylinders, vertical cylinders, and rectangular tanks, including partial fill levels.
EPA requires an SPCC plan when a facility stores more than 1,320 gallons of oil in aboveground containers (or 42,000 gallons underground). Add your tanks below to see if your facility hits the threshold. You can calculate volumes above and click "Add to SPCC Aggregate" or enter values directly.
