Spill Prevention Control and Countermeasures (SPCC)
Therefore, the reason for secondary containment for fuels accomplished by double wall tanks or containment barriers.
Some areas require tanks that protect against punctures. These tanks have a light-weight concrete between the double wall tanks.
The EPA considers shop-fabricated double-walled tanks that employ overfill and leak detection measures and are constructed to industry standards as meeting the secondary containment requirements in the SPCC rule. This clarification can be found in EPA Memorandum, Subject: Use of Alternative Secondary Containment Measures at Facilities Regulated under the Oil Pollution Prevention Regulation (40 CFR Part 112), OSWER 9360.8-38, S426 BMPs for Spill of Oil and Hazardous Substances.
