Guidelines for Environmental Protection Measures at Chemical and Waste Storage Facilities Containment systems should be installed around all liquid chemical or waste storage containers to collect and contain a leak, spill or overfill from the tank, connections, vents or pressure relief devices.

In case the storage of more than one product within a common containment enclosure, whether by initial design or subsequent change in tank service, compatibility should be established to minimize the risk for violent reactions between two or more chemicals.

Containment Capacity

Containments should be sized so as to provide a minimum impoundment volume equal to the greater of:

  • 110% of the volume of the largest tank
  • 100% of the volume of the largest tank plus the greater of 10% of the volume of the largest tank or 10% of the aggregate volume of all remaining tanks.

Construction Requirements

All containment areas should be structurally sound, watertight and able to withstand chemical deterioration and structural stresses from internal and external causes. The secondary containment system should be designed and constructed, coated or lined with a permeability rate to the material stored of 1 x 10-6 cm/sec or less and be chemically compatible with the contents of all tanks within the containment area. The floor of the containment should have a minimum slope of 1.5% towards a sump to ensure that any runoff or spilled material will be contained.
