Preemption Determination No. PD-22(R); New Mexico Requirements for the Transportation of Liquefied Petroleum Gas

Administrative determination of preemption by RSPA's Associate Administrator for Hazardous Materials Safety.

Federal hazmat law preempts New Mexico's cargo tank inspection requirement, as applied to vehicles based outside the State, because the requirement causes unnecessary delay in the transportation of hazardous materials. On the other hand, Federal hazmat law does not preempt New Mexico's cargo tank inspection requirement, as applied to vehicles based in the State, because there is no evidence in the record that the requirement causes unnecessary delay in the transportation of hazardous materials by those carriers. Federal hazmat law also preempts New Mexico's employee examination and identification card requirements, as applied to non-domiciled, LP gas carrier personnel, because the HMR specifically provide that State training requirements may not apply to drivers domiciled outside the State. However, Federal hazmat law does not preempt New Mexico's employee examination and identification card requirements, as applied to domiciled, LP-gas carrier personnel, because the HMR specifically provide that State training requirements may apply to drivers domiciled within the State. Finally, Federal hazmat law preempts New Mexico's LP gas transporter license fee requirements applicable to intrastate and interstate motor carriers that move, load, or unload hazardous materials in commerce because the fee paid to obtain the license is neither fair nor used for hazardous material transportation purposes. Federal hazmat law also preempts New Mexico's vehicle inspection fee, employee examination fee, and identification card fee requirements because the record does not support a finding that the fees are used for hazardous materials transportation purposes. Federal hazmat law does not preempt the New Mexico provisions that require the payment of reasonable licensing, vehicle inspection, and employee examination fees and the deposit of those fees into the State general fund.
