Spill Containment Berms: How to Calculate the Correct Capacity

Secondary containment requirements are regulated by Spill Prevention Control and Countermeasures (SPCC) rules. SPCC applies to facilities with a total aboveground oil storage capacity of greater than 1,320 U.S. gallons or 42,000 U.S. gallons of buried storage capacity. When making a site capacity assessment, include every container of 55 U.S. gallons or more.

All types of hydrocarbon-based oils are subject to SPCC regulations. This includes petroleum, fuel oil, sludge, oil refuse, fats, animal and vegetable oils, synthetic and mineral oils. Industries covered by SPCC include on and offshore drilling platforms, oil derricks and oil rigs, oil refineries, railroad car and truck oil tankers and their loading areas, oil pipelines and some waste treatment facilities. However, SPCC excludes transportation related facilities.

The regulations specify that secondary containment must have the capacity to capture the full contents of the largest vessel in the containment area, plus a freeboard volume to account for any precipitation during a spill. Freeboard of approximately 10 percent is usually adequate.

Spill Containment Berms: How to Calculate Volume

Calculating a spill containment berm size for your application is simple. Just follow these 6 steps:

  1. List the containers that will be in the secondary containment area.
  2. Determine the volume of the largest single container in the list - then add 10 percent freeboard volume.
  3. Convert the gallon volume into cubic feet units. (cubic feet = gallons / 7.48)
  4. Use the berm wall height to convert your volume measurement into an area required. (area = volume / height)
  5. Calculate a length and breadth that fits into the available workspace.
  6. Select a standard berm that meets your calculated needs.
  7. Spill Containment Berms: Customized Solutions

    Sometimes, spill containment berms just don’t fit into the required secondary containment areas, due to oddly shaped rooms or applications. Justrite offers customized berm solutions to fit your exact specifications. Custom berms range from small berms for hard-to-reach spill control, to extremely large spill berms for military applications.
