What is the significance of an aggregate storage capacity exceeding 240 ft³ in CNG installations?

In CNG installations, an aggregate storage capacity exceeding 240 cubic feet is significant because it dictates certain regulatory compliance requirements for the installation. When the storage capacity exceeds this threshold, the facility must adhere to stricter safety and operational regulations set by governing bodies, such as the Department of Transportation (DOT) and other relevant authorities.

This regulation is designed to ensure that larger installations are managed safely due to the increased potential hazards associated with larger volumes of compressed natural gas. These regulations may include more rigorous safety checks, inspections, and adherence to specific standards that do not apply to smaller operations. Thus, understanding the aggregate storage capacity is crucial for compliance with these regulatory frameworks, ensuring both public safety and the safe operation of CNG facilities.
