What is the minimum clearance required between the sides of a 12 ft diameter tank and the banks of the excavation?

• A. 1 ft
• B. 2 ft
• C. 3 ft
• D. 4 ft

Answer: (B)

The minimum clearance required between the sides of a 12 ft diameter tank and the banks of the excavation is 2 ft. This requirement is important for ensuring safety and stability in the installation of underground storage tanks. Adequate clearance allows for proper installation, maintenance access, and reduces the risk of soil collapse or tank damage during operations or environmental changes. Having a minimum of 2 ft of clearance provides enough space for earth movements and allows for effective drainage, which is crucial in preventing water accumulation that could jeopardize the integrity of the tank. This clearance also facilitates safer retrieval in case of maintenance or emergency removal of the tank, ensuring operators have sufficient room to work around the tank without risking damage. It's essential to adhere to this requirement as part of best practices and regulatory compliance in the construction and operation of UST systems.
