| Summary | This final rule removes undue regulatory burdens by adopting the provisions of U.S. Department of Transportation (DOT) special permit (SP) 14175 to authorize a 10-year requalification period and the ultrasonic examination (UE) testing method for DOT specification 3A and 3AA cylinders in flammable and non-flammable, nonpoisonous gas service. This adoption reflects advances in testing technology and will relieve stakeholders of the burden of performing more frequent cylinder requalification. |
