Houston, Texas, Fire Code Requirements on the Storage, Transportation, and Handling of Hazardous Materials

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

The Houston Fire Code contains express exceptions for flammable and combustible liquids and other hazardous materials when being transported ``in accordance with'' DOT's regulations. For that reason, the following requirements in the Houston Fire Code do not apply, and are not preempted by Federal hazardous material transportation law, when the transportation of flammable and combustible liquids is subject to the requirements in the HMR: (1) permits for the storage, handling, transportation, dispensing, mixing, blending or using hazardous materials, including the definition of ``hazardous materials'' as part of these permit requirements; (2) the design, construction, or operation of tank vehicles used for flammable or combustible liquids; (3) physical bonding during loading of the vehicle; (4) unattended parking of the vehicle; and (5) the service rating of the fire extinguisher required to be carried on the vehicle. RSPA denies the request in AWHMT's May 1997 comments to consider a provision limiting the time for unloading flammable or combustible liquids from rail tank cars after delivery, because that requirement is unrelated to the issues raised in AWHMT's application.
