Federal Motor Vehicle Safety Standards; Fuel System Integrity of Compressed Natural Gas Vehicles; Compressed Natural Gas Fuel Container Integrity

Resumo

This document amends Standard No. 303, Fuel System Integrity of Compressed Natural Gas Vehicles, and Standard No. 304, Compressed Natural Gas Fuel Container Integrity. It allows any appropriate fuel to be used for the bonfire test for compressed natural gas (CNG) containers and adds new labeling requirements for CNG vehicles and containers. This document also announces and explains the agency's decision to terminate rulemaking about additional performance requirements for CNG containers that the agency had proposed. Rulemaking may be resumed once revisions to the current voluntary industry standard for CNG containers are completed.
