What is the maximum capacity of LPG and CNG containers that requires a permit for storage?

The correct answer is based on the regulations regarding the maximum allowable quantities of LPG (Liquefied Petroleum Gas) and CNG (Compressed Natural Gas) that can be stored without a permit. In many jurisdictions, a permit is required when the quantity stored exceeds a certain threshold.

In this context, 8.7 SCF (Standard Cubic Feet) represents a typical limit for both LPG and CNG that triggers the necessity for a storage permit. This threshold is important to maintain safety and compliance with local and national regulations. Exceeding this limit means that additional safety measures and oversight are necessary to protect public safety and to ensure proper handling and storage of these flammable materials.

The other capacities listed are too low to require a permit, as they fall significantly below the thresholds established by regulation. Understanding these specific limits is crucial for any operations that involve the storage of these gases.
