For transfer lines between 2 and 4 inches in diameter, how much containment is required?

The requirement for spill containment for transfer lines between 2 and 4 inches in diameter is established by regulations concerning oil transfer operations. According to these regulations, a minimum of 1 barrel of secondary containment is necessary to ensure that any potential leaks or spills from these lines can be effectively managed. This containment capacity is important to mitigate environmental impacts and ensure compliance with safety standards during oil transfer activities.

In the context of spill response and environmental protection, having at least 1 barrel of containment capacity allows for the management of potential spills that could occur during transfer operations, thereby providing adequate time and resources to address any incident before it escalates into a more significant environmental hazard. It demonstrates a proactive approach to preventing and controlling oil spills.

The guidance establishes clear parameters for operators to follow, ensuring that they maintain the necessary infrastructure and equipment for spill containment, particularly for transfer lines that fall within this specified diameter range.
