What is the maximum allowable aggregate capacity for the cross-connection of two oil storage tanks?

The maximum allowable aggregate capacity for the cross-connection of two oil storage tanks is 660 gallons. This specific limit is generally established to prevent potential hazards associated with overfilling and to ensure the safe management of oil products. The 660-gallon threshold is part of regulations aimed at minimizing environmental risks, including spillage and contamination.

Understanding the implications of this limit is crucial for those involved in the management and operation of oil storage facilities. It helps to ensure compliance with environmental standards and safety protocols while also promoting best practices in the storage and handling of flammable materials.

Other options provided represent capacity limits that exceed this regulation. Capacities beyond 660 gallons do not align with safety measures designed to mitigate risks during operation and while connecting storage systems. Thus, adhering to the 660-gallon capacity is essential for maintaining safety and regulatory compliance.
