If we reduce the volume of the largest container to 10,000 litres the total volume becomes 50,000 litres with the largest container housing 10,000 litres.Using the 110% rule the bund would need a capacity of 11,000 litres,using the 25% rule the bund would need a capacity of 12,500 litres therefore the higher volume of 12,500 litres is necessary.Buy and Sell Used Industrial and Lab EquipmentWhether its a site closure,a facility reorganization,or simply excess items,EquipNet manages the sales process while you maximize cash value recovered.Chapter 4 Secondary Containment and ImpracticabilityDec 16,2013·SPCC GUIDANCE FOR REGIONAL INSPECTORS 4-1 December 16,2013 Chapter 4 Secondary Containment and Impracticability 4.1 Introduction The purpose of the SPCC rule is to prevent discharges of oil into navigable waters of the United States
