Abstract
The document summarizes the results of the analysis performed in support for the proposed rule for emission standards and test procedures for natural gas-fueled and liquified petroleum gas-fueled motor vehicles and engines (57 FR 52912) November 5, 1992. The rule also contained procedures by which one can secure an exemption from the Clean Air Act tampering prohibition for an aftermarket conversion (i.e., a vehicle modification which allows the vehicle to operate on a fuel other than the fuel it was designed and certified to operate on). These procedures, based on the current new vehicle certification procedures, were intended to clarify how one can avoid application of the EPA tampering policy on a conversion by providing a method of demonstrating that a vehicle will continue to meet applicable emission standards after the conversion.
