What type of unit is required to be registered with AFS?

The transport container unit is required to be registered with AFS because it is essential for the safe and legal transportation of compressed natural gas (CNG). These units must meet specific safety standards and regulations to ensure that CNG is handled properly during transit, minimizing the risk of leaks or accidents. Registration with AFS (the appropriate regulatory body) ensures compliance with state laws and industry standards, thus promoting operational safety and environmental protection.

While fuel storage units, maintenance units, and testing units play critical roles in the overall ecosystem of CNG handling and usage, they do not necessarily require registration with AFS in the same way that transport container units do. The focus on transport container units underscores the importance of proper oversight in the transportation process, which is a vital component of the CNG supply chain.
