Under what condition will AFS not issue a CNG Form 1004?

The condition under which AFS will not issue a CNG Form 1004 is when the transport is deemed unsafe for CNG service. This is crucial because safety is the primary concern when dealing with compressed natural gas, which is highly flammable and requires adherence to specific safety regulations and standards. If the transport vehicle does not meet these safety standards, it poses a significant risk to the driver, other road users, and the environment. Therefore, the issuance of a CNG Form 1004 is conditional on ensuring that the vehicle is equipped and maintained in a manner that ensures safe operation.

While the other conditions listed, such as exceeding weight limits, lacking proper driver training, or not meeting environmental standards, are also important considerations, they do not directly address the immediate safety of the transport vehicle itself in the context of CNG service. The primary focus of AFS is to ensure safe handling and transportation of compressed natural gas, which is why the assessment of safety is prioritized.
